TANDBERG Television iPlex OverviewTANDBERG Television’s iPlex is the industry’s first networking device with advanced content manipulation techniques that enable efficient bandwidth-saving delivery of the highest quality video and audio, regardless of the content’s point of origin or format. iPlex is a carrier class, modular, reliable, and expandable chassis-based hardware-networking platform.
iPlex is designed for the efficient delivery of Internet data (IP), video (MPEG-2 and MPEG-4 AVC), and streaming (IP) video/audio across any broadband net-work or IP backbone, such as DSL or fiber. iPlex is content-aware, and enables the connection of different transmission media at different rates. It can multiplex, de-multiplex, format and inject IP data in-band into MPEG-2 transport streams, retrieve IP content from MPEG-2 transport streams, and transmit IP and MPEG-2 data with full Quality of Service (QoS).
iPlex can function as a content switching, routing, video rate changing and multi-plexing device in the core of the network, connecting multiple streams of data and MPEG traffic, and intelligently routing the traffic to its appropriate destination. The final client can be a PC with appropriate client application, a digital set-top box, or a residential gateway capable of accepting video/data streams and provid-ing video outputs to standard television sets.
The following are features of the TANDBERG Television iPlex:
• 1 RU unit
• 8 PMC slots, which support all of the current PMCs
• Front panel with LCD and six keys
• Built-in ports (10/100 Ethernet, two GE on SFPs for data transfer, console serial port)
• Routing of IP traffic
• Video encoding
• Delivery of MPEG-2 and MPEG-4 AVC over IP networks
• Configuration via Web GUI, CLI, or SNMP interfaces
• High reliability with all components redundant
• NEBS level 3 compliant and certified
NEBS compliant (NetworkEquipment Building Systems
compliant) Adhering to standardsfrom Telcordia for equipment
used in telco central offices(COs). Most equipment must beNEBS certified before it can beintegrated into carrier facilities.NEBS specifications deal withpower management, electricalshielding, disaster preparation
and hardware interfaces.

Real-TimeMPEG-2 EncoderPlus (RTME Plus)
This RTME Plus encoder offers more audio encoding options. It supports four channels (two stereo pairs) of audio for encoding into either MPEG-1 Layer II or Dolby Digital AC-3 audio. The audio source can come from any of the following input interfaces: unbalanced, balanced, AES or embedded Serial Digital Interface (SDI). The encoder supports analog and digital video sources. For an analog video signal, S-Video or composite video inputs are available for configuration. Alter-nately, the encoder can receive digital video input through the SDI.
Real-TimeMPEG-4 AVC
Encoder
The MPEG-4 AVC Encoder uses the same front end as the Encoder Plus. It sup-ports H.264/MPEG-4 AVC video and four channel (two stereo pairs) of audio for encoding using the H.264/MPEG-4 AVC for video and AAC/MPEG-1 Layer 2 codec for audio. The audio source can come from any of the following input inter-faces: unbalanced, balanced, AES or embedded Serial Digital Interface (SDI).
Real-TimeMPEG-4 AVC
UltracompressionEncoders
The Real-Time MPEG-4 AVC Ultracompression Encoder submodule uses two daughter cards: one for Standard Definition video and another for High Definition uncompressed digital video. Accordingly, the MPEG-4 AVC Ultracompression encoder offers two factory-installed input interface options:
• MPEG-4 AVC Ultracompression HD Encoder with HD-SDI Interface: this interface onlysupports digital uncompressed video. It can be configured to accept either HD-SDI or SD-SDI inputs.

• MPEG-4 AVC Ultracompression SD Encoder with SD Interface: this interface only supportsstandard definition video signals, both analog Composite, S-Video, and digital (SD-SDI), inthe exact same arrangement as the MPEG-2 Encoder Plus and the H.264 MPEG-4 AVCEncoder.
These encoders use dual slots, see the illustrations. Both encoders compress the input video to MPEG-4 Part 10 (H.264). Both interfaces support embedded audio in the digital interface, as well as analog balanced or unbalanced audio. They also support digital AES audio.
The encoders support between four and six audio stereo pairs, depending on the selected audio compression scheme. The first two audio pairs can be analog-bal-anced or unbalanced signals, connected through the 37-pin micro-D connector. When using AES signals, the 37-pin micro-D connector allows for up to four ste-reo pairs, plus an optional clock sync output.
The remaining channels are only available as embedded audio in the HD or SD Encoders.
HD Encoder The HD encoder provides one BNC for uncompressed digital video input, with support for both HD-SDI and SD-SDI interfaces, as well as the audio interface (see the illustration). The upper part of the front view is a blank-face panel.
NOTEThe clock for the AES audio inputs MUST be synchronized with thevideo frame rate.
NOTEThe audio cables used in the MPEG-2 Encoder Plus and in the MPEG-4 AVC Encoder are compatible with this module.
30
iPlex Web Interface User Guide
SD Encoder The SD encoder option provides two BNCs for uncompressed analog or digital video input. These two BNCs can be configured in software to be two composite inputs, one S-Video input, or one SDI input. The SD encoder also includes the audio interface, which is identical to that of the HD encoder.
NOTEAny analog video input to the card must be time-base stable and any inputs coming directly from any kind of VTR (such as ½” con-sumer VCRs) may show as very unstable inputs without the use of a time-base corrector/frame synchronizer.

UltracompressionSingle-slotEncoders
The single-slot Ultracompression encoders are a denser version of the dual-slot module, with improved functionality. The advantages for a single-slot encoder are:
• Fits in a single slot, so 8 of them can be fitted in one iPlex chassis.
• Improved video quality compared to the dual-slot encoder.
• Up to 8 stereo audio pairs can be encoded by each card, regardless of encoding mode.
HD Single-slotEncoder
The Single-slot HD encoder provides one BNC for uncompressed digital video input, with support for both HD-SDI and SD-SDI interfaces, as well as the audio interface. The interface details are the same as those of the dual-slot version.
32
iPlex Web Interface User Guide
SD Single-slotEncoder
The Single-slot SD encoder option provides two BNCs for uncompressed analog or digital video input. These two BNCs can be configured in software to be two composite inputs, one S-Video input, or one SDI input. The SD encoder also includes the audio interface, which is identical to that of the HD encoder.
DSP 4PAC (MediaProcessor)Submodule
The DSP 4PAC, or Media Processor, submodule is a high performance, program-mable platform for the video headend platform. Software is licensable from TANDBERG Television to give the Media Processor a wide range of functionality, including MPEG-2 to MPEG-4 AVC Transcoding. The DSP 4PAC (Media Pro-cessor) Submodule uses four DSPs to give it the performance needed to meet these applications’ demands.
As multi-function devices, 4PACs or Media Processors can do transcoding or tran-srating. When they do transcoding, the 4 DSPs work cooperatively, and provide ONE channel of transcoding, or, one transcoder input and one transcoder output ports. When configured to do transrating, they can provide multiple transrator input and output ports. The number of ports they provide depends on the config-uration of the Media (DSP 4PAC) Processor:
• If configured for High, it is one service per DSP, and a 4PAC will provide 4 transrator input /output ports.
33
iPlex Web Interface User Guide
• If configured for Medium, it is two services per DSP, and a 4PAC will provide 8 transratorinput / output ports.
• If configured for Low, it is three services per DSP, and a 4PAC will provide 12 transrator input/ output ports.
DSP 6PACTransratingSubmodule
The DSP 6PAC Transrating Submodules are plug-in modules that provide the per stream video processing capability needed for rate shaping and rate reduction. Each DSP submodule provides transrating capability for up to six individual video programs.
MPEG-4 AVCUltracompression
Transcoder
The MPEG-4 AVC Ultracompression Transcoder provides real-time transcoding from MPEG-2 to H.264. H.264 Video provides a better quality as well as 40-60 % lower bitrates compared to MPEG-2. The transcoder also provides full live video compression up to HD. This is a dual-slot transcoder.
The MPEG-4 AVC Ultracompression Transcoder accepts both SD and HD Video Format inputs. It provides six Audio channels and Dual Mono Split with a repli-cated channel. The Codec transitions between the two channels seamlessly (except possibly for a signal level discontinuity) and without a restart.
Video stream is always transcoded. Audio streams in the input program can be selected for pass-through or transcoding. For transcoding, either two stereo pairs or one 5.1 channel is supported.
The output of AVC Ultracompression Transcoder contains two programs:
MEDIAPROCESSOR
MP 1
MP 2
MP 3
MP 4
34
iPlex Web Interface User Guide
• The first program contains the main video and all the transcoded audio streams and passedthrough streams. The program number for the first program is the same as the programnumber of the input source.
• The second program contains the PIP video. The PIP program number is one plus the mainprogram number. The PMT PID for PIP is dynamically generated to be a unique one.
The PIP video PID is by default 0x201. If this PID already exists in the input pro-gram, a unique PID is generated for the PIP video stream.
Unique PID values are also dynamically generated for any audio channels that are replicated and transcoded.
The transcoder has a scan conversion capability, which controls the picture resiz-ing, see page 382.
An AVC Ultracompression Transcoder card’s profile and its front on a daughter card are shown as follows.

ASIPlusSubmodule
The ASI Plus submodule provides bidirectional ASI ports and scrambling capabil-ity. The submodule contains four physical connectors; each pair of connectors can be independently configured as two ASI inputs or one ASI output, replicated over the two connectors. The ASI inputs can be used to receive content from profes-sional satellite or cable receivers, video servers, table generators, or any other device with ASI outputs. The ASI outputs can be used to drive multiplexers, satel-lite or cable modulators, or any other device requiring an ASI signal.
This submodule also provides DVB Common Scrambling functionality, which is independent of the physical ASI ports. Connection to Subscriber Management System is done through the chassis Gigabit Ethernet ports.
The ASIPlus submodule is distinguished by its label (ASI Plus) and by BNC con-nectors (red PMS 032).

iPlex Web Interface User Guide
DVB Transport StreamA Digital Video Broadcasting (DVB) Transport Stream includes video, audio, or data, Service Information (SI), and Conditional Access System (CAS) informa-tion. The Conditional Access System contains the entitlement for specific pro-grams and customer service information. This information has two forms: Entitlement Management Messages (EMMs); that is, who can receive programs and what programs they can receive; and Entitlement Control Messages (ECMs); that is, how to unscramble the program information.
Data InjectionThe purpose of data injection is to format and inject data into an MPEG-2 Trans-port Stream. Data needs to be formatted into transport packets in order to be injected.
Ports and PacketizersPorts are the means by which data is input to an iPlex. If data is not in transport format, a packetizer is used to convert the data to a transport format.
Input Port PacketizersMPEG-2 Transport Stream (M2T) Packetizer
■ Input: Data that is already in MPEG-2 TS packet format, but the continuitycounter may need fixing.
■ Operation: Delimits the packets and passes them to the multiplexer.
Data Piping Packetizer
■ Input: Byte stream or UDP datagram.■ Operation: Copies the input data into the payload of MPEG-2 TS packet
format.MPEG-2 Section Packetizers
■ Input: Data is in sections.■ Operation: Divides the sections into MPEG-2 TS packet format.
ECM (Entitlement ControlMessage) Private conditional
access information that carriesthe control word in a secure
manner along with privateentitlement information.
EMM (Entitlement ManagementMessage) Private conditional
access information that specifiesthe authorization levels of
subscribers or groups ofsubscribers for services or
events.
40
iPlex Web Interface User Guide
SME Network Interface PacketizersIP Traffic Packetizers
■ Input: IP payload.■ Operation: Adds an MPE header to create a section then divides the sections
into MPEG-2 TS packet format.
MPEG-2 Transport Stream PacketsThe MPEG-2 Transport Stream packet is 188 bytes long, with 4 bytes of header.
The main fields in the header are as follows:
• sync byte—always 0x47, which allows delimitation;
• a packet identifier (PID) differentiates between multiple streams;
• continuity counter counts from 0 to 15 on consecutive packets of the same PID.
MPEG SectionsSections are blocks of data of up to 4096 bytes in size. They are divided into Trans-port Stream packets for transmission. MPEG-2 PSI and DVB SI tables are always in sections.
The private data area can be up to 4093 bytes, with 3 bytes of header.
41
iPlex Web Interface User Guide
Packetizing SectionsSections become the payload of MPEG-2 Transport Stream (TS) packets; how-ever, they can be larger or smaller than the TS packets themselves. Section packing improves the efficiency of the stream.
MPEG Transport Over Packet NetworksThe iPlex supports transmission and reception of MPEG Transport Streams over traditional packet networks. In general terms, a number of 188-byte MPEG Trans-port Packets combine to form the payload of a network PDU. The diagram below illustrates the Network Encapsulation Process. The Protocol Header and Protocol Trailer are specific to the network protocol used.
iPlex Supported ProtocolsThe iPlex supports the following protocol combinations:
MPEG Over UDP/IP
PDU (Protocol Data Unit) Thetechnical name for a frame of
data transmitted over a data link(layer II) in a communications
network.
42
iPlex Web Interface User Guide
• Over Gigabit Ethernet
• Over ATM
■ Using RFC-2684 LLC Encapsulation for routed non-NLPID protocols(Classical IP)
■ Using RFC-2684 LLC Encapsulation for bridged protocols (Bridged Ethernet)
MPEG Over RTP/UDP/IP
Using RFC 2250 (MPEG2 over RTP) and RFC 1889 (RTP):
• Over Gigabit Ethernet
• Over ATM
■ Using RFC-2684 LLC Encapsulation for routed non-NLPID protocols(Classical IP)
■ Using RFC-2684 LLC Encapsulation for bridged protocols (Bridged Ethernet)
MPEG Over AAL-5 Native ATM.
MPEG EncapsulationThe following two figures illustrate MPEG packet formats over Gigabit Ethernets: The first diagram shows MPEG over UDP/IP over Gigabit Ethernet encapsula-tion, while the second shows RTP encapsulation over Gigabit Ethernet. Note that the only difference between these two is the addition of the RTP header in the Protocol Header section.
The next diagram illustrates MPEG over UDP/IP over ATM, with Classical IP encapsulation (RFC 2684 LLC encapsulation of routed protocols). The AAL-5 payload contains the IP packet plus a RFC 2684 header and a trailer. The whole AAL-5 PDU is then submitted to the ATM layer for further segmentation into ATM cells. The other RFC 2684 ATM encapsulations are similar the changes would show the presence of an RTP header after the UDP header for RTP, and the
43
iPlex Web Interface User Guide
presence of an Ethernet MAC header before the IP header for bridged Ethernet encapsulation.
The last diagram shows the MPEG over Native ATM encapsulation. It is very sim-ilar to the previous diagram; the difference is the removal of the UDP/IP and RFC 2684 layers (this is why this mode is called “native” ATM, as it does not have any additional protocols). This mode has an empty protocol header and is more band-width-efficient than the other ATM modes. However, the presence of UDP/IP headers in the other modes allows for support of multiple Single-Program Trans-port Streams over a single ATM Virtual Circuit; this is not possible in native mode.
NOTEFor further information see Port Configuration and Statistics, sec-tions on ATMIn, page 305, and ATMOut configuration, page 326. Also see, ATM Forum, “Audiovisual Multimedia Services: Video on Demand Specification 1.1,” March 1997.

IPv6 SupportSupport for IPv6 is available only for the Gigabit Ethernet ports.
VLANsA VLAN configured with IPv6 addressing will not accept IPv4 traffic; similarly, an IPv4 VLAN will not process any IPv6 packet.
UDPOut/RTPOutIPv6 addressing is available as an option only for the UDPOut and RTPOut ports with multicast destination address. IPv6 packets can only be routed to tagged or untagged IPv6 VLAN port. Support of an IPv6 datagram is restricted to transmis-sion out of the system; any IPv6 datagram received by the system is not processed and is dropped.

User activity logging enables system administrators to track any changes made to the system. This is especially important for broadcast facilities, where an operator mistake can take channels off-air. With this feature, an audit trail is created and the system administrator can pinpoint who made what changes at what time.
InformationLogged
The iPlex will log the following information:
• The time the change happened.
• The username of the person executing the change, or the word STARTUP if it is aconfiguration being applied from boot (startup-config).
• The origin of the change request (IP address of the originating machine for SNMP or Web, orconsole name for CLI).
• The interface used (for example, web, CLI or SNMP).
• The type of operation (ADD, MODIFY, REMOVE or INFO). Operations are classified asfollows:■ ADD operation creates a new object. Example: adding a VLAN or a logical port.■ MODIFY operation changes an existing parameter. Example: change a port's
destination IP address or TTL.■ REMOVE operation deletes an object. Example: removing a VLAN or a logical
port.■ INFO operations track pages visited using the Web interface.
• The affected port, or the word SCM if the operation pertains to a system parameter.
• The actual operation performed, and any parameters of this operation (for example, if an IPaddress is changed, the new address is logged).
All the user activity logs include the word USER-LOG to facilitate filtering of this information in the system logs.
Examples of Logs The following are examples of logs:
• User Bob creates a new UDPOut port using the web, from host 192.168.4.112:Nov 4 18:15:50 iplex ctrlLayer[7551]: USER-LOG:192.168.4.112 : bob : WEB : ADD : UDPOut1/0 : Create UDPOut :Associated: ATM1/4, Status: OK
• User Tina modifies the input stream type of the ASIIn1/1 port using the SNMP v2 protocol:Nov 4 18:28:34 iplex ctrlLayer[7553]: USER-LOG :192.168.4.112 : N/A : SNMP : MODIFY : ASIIn1/1 : Input StreamType : Input Stream Type: DVB (0x1), Status: OK
■ Note that no user name is actually logged because SNMPv2 does not have thenotion of user authentication. If you need that, use SNMPv3.
NOTEThere is no logging of the operation of reading a variable or param-eter through CLI or SNMP.

To enable user activity logging, see Configuring SCM Logging on page 144. The logs will be available in the iPlex and will also be written to an external syslog server if so configured.
Viewing UserLogs
To view the user activity logs in the iPlex, see Log on page 161.
Changing PasswordsChanging a user’s password is the same thing as editing a user’s information. See Edit a User’s Information on page 55.
WARNINGDue to the limited space for logs in the iPlex, the potentially large number of messages that can be generated by this feature, and the fact that logs do not persist across reboots, TANDBERG Television strongly recommends that an external syslog server be used if log persistence is important. See SCM General Configuration on page 137.
NOTEOnly root users can enable this feature. Users in the adminis-trator or operator groups will not be able to see the User Log-ging screens.
NOTE1. TANDBERG Television recommends that you change each user’s password on a regular basis.2. Only root users can exercise this feature. Users in the admin-istrator or operator groups will not be able to see the Adminis-tration screens.

Changing the Session TimeoutThe iPlex is set to timeout 30 minutes after no activity. To change this timeout time, perform the following procedure:
1 Click Maintenance.
2 Click User Information (see User Interface on page 159) and enter the newsession timeout time.
Backing up the System Configuration FileThe iPlex uses the information in the startup configuration file whenever there is a reboot. This startup configuration then becomes the running configuration until you change the file. As you configure your system, TANDBERG Television rec-ommends that you periodically back up your running configuration file. You can do this in one of two ways:
• Copying your running configuration file to your startup configuration file. When your systemreboots, it will use the latest startup file (see Copy Running on page 123).
• Copying your running configuration file to a selected (Flash) destination. The system willreboot using your current startup file, but you can then apply the saved file to become yourrunning configuration file (see Apply Config on page 121).
To back up your running configuration file, perform the following procedure:
1 Click Configuration and then Config File.
2 Click Copy Startup (see Copy Startup on page 122) or Copy Running andfollow the instructions.
Looking up the Status of Optional LicensesSome features require optional licenses to function. To find out which features have installed licenses, see License Statistics on page 90.
NOTEOnly root users can exercise this feature. Users in the adminis-trator or operator groups will not be able to see the Administra-tion screens.

Looking up the Software VersionTo find out which version of the software is running on the unit, see Software Sta-tistics on page 84.
Upgrading the SoftwareWhenever software is upgraded, each element of the system must be rebooted; thus, the procedure for upgrading the software depends on whether the iPlex is configured for non-redundant or redundant operation. Redundant systems must be upgraded in a fashion that does not disrupt service as the various system ele-ments are rebooted.
The following upgrade cases are possible:
• Non-redundant systems
• Redundant SCMs with non-redundant MCMs. Redundant MCMs with non-redundant SCMs.Fully-redundant systems.
NOTES1. Upgrading the software preserves the existing configuration files. However, the system must be rebooted for the new software to take effect. The latest startup configuration file will be used for the reboot. See Backing up the System Configuration File on page 58 for guidance on backing up your configuration files.2. Service will be disrupted whenever you reboot a system that is not fully redundant. To boot more quickly to minimize the downtime, consider using a startup configuration file that has no saved defaults (see Copy Startup on page 122).
59
iPlex Web Interface User Guide
Non-redundantSystems
The following diagram shows the conceptual software upgrade procedure for non-redundant systems:
The steps to upgrade are:
1 Load the new software to the appropriate boot source. Click Maintenance,then Software Upgrade. See Software on page 158.
2 Select the boot source for the new software. See SCM Software Configurationon page 139 to specify the new boot source.
3 Reboot the system. Click Configuration, then SCM, then Reboot. See Rebooton page 139. In this situation, rebooting the SCM reboots also all of the othersystem components and they get whatever software the SCM has. The entireiPlex will be operating with the new software after the rebooting is finished.
4 Do this final step only if necessary. To return to the previous software, use theprocedure described in step 3 above after resetting the boot source in step 2to the previous software. The entire iPlex will be operating with the previoussoftware after the rebooting is finished.
NOTEIf you are currently booting out of Flash 1, for example, it is
recommended that you load the new software into Flash 2. Then ifyou have any issues with the new software, you can return to youroriginal configuration by rebooting out of Flash 1 while you resolvethe issues. This procedure presumes that you will “double-buffer”the boot source each time you perform a software upgrade.
NOTEService will be disrupted when you reboot the system.

ConfigurationFiles
The Startup Config File is used when the system reboots and then becomes the Running Config File. As you configure the iPlex, you edit the running config file.
You can back up the running config file to Flash memory (see Copy Running on page 123) and give it a new name. You can replace the current startup config file (see Copy Startup on page 122) so that the currently running config file will be used for the next reboot. See Backing up the System Configuration File on page 58 for an overview of configuration file backup.
You can remove a backed-up config file (see Remove Config on page 124) or replace the current running config file with a backed-up config file (see Apply Con-fig on page 121).
You can download a config file from the Internet (FTP site) to Flash memory (see Download Config on page 124) or upload a config file to the Internet (see Upload Config on page 124).
The Flash memory available for storing configuration, data, and log files is 11 MBytes.
Data Files Data files are used with FileIn ports (see FileIn Port Configuration and Statistics on page 307). Before configuring the FileIn ports, you must first download the data files (see Download Data File on page 127) from the Internet (FTP sites) and store them in Flash memory. You can also remove data files from memory (see Remove Data File on page 128).
The Flash memory available for storing configuration, data, and log files is 11 MBytes.
Log Files Each iPlex subsystem has log files that users can view (see Log File on page 161) and clear (see Clear Log on page 161). You can also upload (see Upload Log on page 161) log files to an FTP server. In addition to system logging, user activity can be logged. See User Activity Logging on page 55 for an overview of user activ-ity logging.
The memory available for storing log files is as follows:
• Each SCM has 979 KBytes available for storing log files. This memory is rotated internally sothat it never runs out of space (i.e., only the most latest logs are stored and the oldest logs aredeleted).
NOTEAs you configure your system, TANDBERG Television recommends that you periodically back up your running configuration file.
63
iPlex Web Interface User Guide
The Flash memory available for storing configuration, data, and log files is 11 MBytes.
Software Files You upgrade the iPlex software by connecting each SCM in the system to a boot software source (see SCM Software Configuration on page 139) and then rebooting the unit (see Reboot on page 139). See Upgrading the Software on page 59 for the strategies on how to reboot the units to minimize or eliminate service disruptions for partially or fully redundant systems.
You can download the software files from the Internet (FTP site) and store them in Flash memory (see Software on page 158) or upload software files from Flash memory to the Internet.
• If the software file is too big to fit in the Flash 1 or Flash 2 partition, you must store it in theFlash 1+2 partition.
• You can copy a software file from the Flash 1 partition to the Flash 2 partition (or in oppositedirection).
The memory available for storing software files is as follows:
• Flash 1 partition: 13 MBytes
• Flash 2 partition: same as Flash 1 partition
• Flash 1+2 partition: 26 MBytes
WARNINGDue to the limited space for logs in the iPlex, the potentially large number of messages that can be generated by this feature, and the fact that logs do not persist across reboots, TANDBERG Television strongly recommends that an external syslog server be used if log persistence is important. See SCM General Configuration on page 137.
NOTETANDBERG Television recommends you keep a copy of the current software somewhere before doing a software upgrade in case you need to return to the current release for any reason.

port. If a loss of sync occurs, an SCM flip will occur. For example, if you enable the Loss of GE1 Sync alarm and then pull the cable from the GE 1 port, an SCM flip will occur. If the Loss of GE2 Sync alarm is not enabled and you pull the cable from the GE2 port, there will not be an SCM flip.
SynchronizingFiles
Selecting the Sync Files button in the Redundancy Configuration page (see above) results in the synchronization of file systems between the primary SCM and the backup SCM. Then the files contained in the flash directory, the pcmcia/data directory, and the config directory transfer from the primary SCM to the hot-standby SCM. The exception to this is the Startup Config file in the config directory. The Startup Config File transfers automatically to the backup SCM at initialization.
Configuring Media RoutingMedia routing tools enable you to designate Program Routes, Add Programs, Stream Routes, and Remove Selected items. If you are using the previous Media Routing interface, see Former Media Routing Configuration on page 459.
Basics of MediaRouting
The iPlex provides two types of media routing: program routing and stream rout-ing.
A Transport Stream, containing unique packet identifiers (PIDs), received by the iPlex, may contain a few elementary streams multiplexed together. The iPlex soft-ware analyzes the content and allows you to reorganize the stream elements into new programs, which it can then route to multiple output ports.
The Transport Stream content elements are as follows.
Transport Stream: One or more programs, each of which contains one or more elementary streams and other streams, such as data, multiplexed together. The Stream information contains all the PID information in the Transport Stream along with DVB table information.
Program: A number given to a service that is used to reference one or more ele-ments. The Program information is as follows: MPEG program number, DVB name, DVB original network ID, and DVB service type. That is, the program iden-tifier number, the name of the program, the original network number assigned to it, and the service type; for example, Digital Television Service and Data Broadcast Service.
Element: An entity, such as video or audio data, which is put together with other elements to make up a program. The Element information contains the PIDs associated with the program and element type. There is a direct correlation between the Program and Element information that comes from Program Specific Information (PSI) described in the MPEG specification.
NOTEThe Sync Files button is only available if you have redundant SCMs.
103
iPlex Web Interface User Guide
To have a better understanding of these definitions, see Programs, Elements and Streams List Statistics on page 406.
Program Routing vs.Stream Routing
The simpler of the two is stream routing. It is used to route individual PIDs from inputs to outputs, optionally remapping the PID value. This means that the iPlex will take all packets of PID X of the specified input and transmit them of the spec-ified output, changing the PID to Y. No changes are made to any output tables.
Program routing relies on the input PSI tables. Program routing means that the iPlex takes all the elements from Program X in the specified input and routes them to the specified output as Program Y, resolving any conflicts. In this mode, the iPlex parses the PMT for the input, identifies all of the program elements, routes these program elements, and copies any PAT, PMT, and SDT entries (including any descriptors) from the input to the output. The output tables are modified accordingly.
The iPlex will also automatically resolve any PID conflicts. For example, if the routed program has an element on PID 0x200, but PID 0x200 is already in use in the output, the iPlex will automatically remap the incoming PID 0x200 to a free PID and adjust the tables accordingly. As well, if the input program changes (for example, a new PID with an additional audio channel is added), the iPlex will auto-matically adjust by routing any new elements, resolving any PID conflicts, and adjusting the tables.
Setup MediaRouting
The Media Routing page opens with the selection from three groups shown below.
The set of selection items in each group depends on the configuration of your iPlex system. The following illustration is an example of Group 1.
104
iPlex Web Interface User Guide
The first step is to select 2 or 3 groups of ports to work on. For example, you can select AVCXcdr in group 1 and UDPOut in group 2 to route content between the transcoders and the UDPOutput ports. Another example can be UDPIn in group 1, AVCXcdr in group 2 and UDPOut in group 3 to route some contents between the UDPInput ports and the UDPOutput ports using the transcoders.
Next to the port type, you can specify the number of ports you want to create. For example, if UDPIn is selected in group 1, AVCXcdr in group 2, and UDPOut is selected in group 3, then x number of UDPInput ports and x number of UDPOutput ports will be created, where x is the number of AVC transcoder ports selected in group 2.
When ports are needed to be created, you can also specify basic parameters, such as port number, IP address, or VLAN ID. You can also use an offset for each of those parameters. For example, if you set IP to 224.1.1.1 and offset to 1, and 4 UDPIn ports need to be created, UDPIn1/0 will have 224.1.1.1 as an IP, UDPIn1/1 will have 224.1.1.2 and so on. See selection example in the illustration that follows.
Media RoutingPanels
When you press the NEXT button, you see the page with five panels. The upper three panels represent the port sections. The upper left-most panel shows the ele-ments for an input port; the middle panel shows the elements for a processing (or internal) port, transrating or transcoding. The upper right-most panel shows the elements of an output port. See illustration that follows.

Configuration FileiPlex configuration files are user-readable ASCII files. The text of a configuration file is equivalent to the CLI commands that would be entered to create the config-uration. Configuration files can be edited any time using a standard text editor.
The Config File menu item displays the following links: Apply Config, Copy Star-tup, Copy Running, Remove Config, Upload Config, Download Config, Edit Con-fig, and Push Config.
Apply Config The Apply Configuration File page allows you to select a configuration file and use it for your system or some parts of it. You can also Replace the file.
The page contains the following parts:
• File Name: list of configuration files to select from
• Sections: The Sections in the configuration file can contain any combination of one, two orall four sections as follows:■ System■ Blade)■ Media Routing■ Replace
The section Blade contains the configuration for a media blade.
When you select a Configuration File from the File Name list, the control layer will parse this file and display the list of sections this file contains. The parsing allows you to verify what is inside the configuration file before you decide which sections you want to apply. Selecting the sections from the configuration file pro-vides significant flexibility for configuring your system.
After you made your selections and clicked Apply, the web interface displays Applying configuration file ... page, which represents a list of steps of the cho-sen configuration being applied to your system along with their states.
121

Example below shows a progress report.
When the operation is complete, you can click the View Report link and see the Apply Config Report page.
The Replace option is enabled by default. The following example explains its functionality: a config A file is active, and you need to apply a config B file. If Replace option is on, config A will be replaced by config B. The replac-ing and this is performed in a “smart” way: all elements common between con-fig A and config B will be left unchanged. The rest of the file will be modified. If the Replace option is off, config B will be added to config A: each element in config B not present in config A will be added and the rest will be left unchanged.
Copy Startup Copy Startup copies the running configuration file to startup configuration val-ues; a message will display saying if it was successful or not. This is generally applied when you want to make sure that this is the configuration that comes up

when the system reboots. The two default files are running-config and startup-config.
Copy Running Copy Running copies the running configuration data to a file in a selected desti-nation (Flash) and allows you to name the file.
You can set a full or partial configuration using the options in the Sections list (see Copy Configuration File page below), and then copy it to a file.
The Sections list provides flexibility in setting configuration as follows:
• System: SCM configuration
NOTEAfter you change your system and are confident everything is work-ing correctly, TANDBERG Television recommends that you copy the configuration file at that point to the startup file in order to have a known starting point should the system ever have to reboot.
TIP When you save theconfiguration file to the startup file
without saving the defaults, youwill boot about 25 percent faster.
If you ever need the factorydefaults again, just recopy the
running configuration file with thedefaults enabled.
NOTEBefore making any changes to your system, TANDBERG Television recommends that you save the current state of your system by copy-ing the currently running configuration file to a backup file (you choose the name of the file) in order to be able to go back to the cur-rent configuration should you ever need to do so.

ConfiguringStatic ARP
To improve chassis reliability when transmitting high volumes of unicast traffic, you may wish to use static ARP.
When transmitting unicast traffic, the iPlex needs to know the destination MAC address of the device that should receive the traffic. This will be the MAC address of the end device if it is in the same subnet as the gigabit port, or the MAC address of the next-hop gateway. The MAC address information resides in the ARP table, which relates IP addresses with their corresponding MAC addresses. If this infor-mation is not known, the outgoing traffic may flood the SCM processor. This may be an issue in the following scenario:
By default, ARP entries age out in 300 seconds. If the destination device (or next-hop gateway) goes down, then in 300 seconds that information will be removed from the ARP table and the iPlex may stop functioning.
These issues can be corrected with Static ARP entries in the table. Static ARP entries do not age out, and are entered manually. This ensures that the iPlex has the necessary information to forward unicast traffic.
The disadvantage of using Static ARP is that if the destination device or gateway is replaced, the iPlex needs to be manually reconfigured for the appropriate MAC address.
Entering Static ARPValues
To enter static ARP values:
1 Select Configuration > IP Routing > Network Routing.
2 In the Network Routing screen, in the Static ARP section, enter the target IPaddress (end node or next hop gateway) and the corresponding MAC address.
3 Click Add, then click Apply.
4 To delete entries, select the check box for that entry and click Delete, thenclick Apply.
NOTEThe iPlex does not support entering ATM routes for adapters in bridged mode.

Configuring aVLAN
The VLAN Configuration page allows you to configure VLANs. After entering values, click Add to create a new VLAN or Delete check boxes and Delete button to remove entries. After completing the configuration, click Apply.
RIP (Routing InformationProtocol) A simple routing
protocol that is part of the TCP/IPprotocol suite. It determines a
route based on the smallest hopcount between source and
destination.
NOTES1. IPv6 and IPv4 do not coexist in the same VLAN, and they have tobe created in separate VLANs. See IPv6 Support on page 45.2. If you need to change the settings of a VLAN, you must delete that VLAN and create a new setup using the same VLAN ID.
VLAN (Virtual LAN) A logicalsubgroup within a local area
network that is created viasoftware rather than manually
moving cables in the wiringcloset. It combines user stations
and network devices into a singleunit regardless of the physical
LAN segment they are attachedto and allows traffic to flow more
efficiently within populations ofmutual interest.
VLAN Tagged Packets VLANtags used to define multiple LANsin the same physical segment. A
tagged packet has an extraheader added between the layer
2 and the layer 3 headers (thetag) that indicates to which VLANit belongs. Typically only switchesand routers handle tags, not end-
hosts.

• Bridge Priority: This is the two-byte MSB of the bridge identifier. It controls which device inthe network will become the root bridge. The lower the value, the higher the priority of thedevice.
Understanding theSpanning Tree
Protocol
The Spanning Tree Protocol is used by layer-2 bridges to remove loops from the network topology. This is necessary because otherwise the packets would go for-ever around the loop, causing the network to stop functioning due to excessive traffic. The protocol identifies a subset of the network topology that has the fol-lowing properties:
• It spans all nodes in the network (“spanning”).
• There is only one path between any pair of nodes in the network (that is, the topology is a“tree”).
Links that do not belong to the spanning tree are not used for communication, but are held in reserve (that is, the bridge ports are “blocking”). If one of the links in the tree is broken or lost, the Spanning Tree Protocol will automatically recover from this situation by enabling one of these links (that is, it will be placed in “for-warding” state). To build the spanning tree, one of the nodes (bridges) is elected to be the root of the tree (the “root bridge”). Each bridge in the network has an 8-byte identifier.
Priorities are inversely proportional to the numerical value of the identifier. The bridge with the lowest identifier is the root bridge. The two most significant bytes of the identifier are user-defined priority values. The remaining six bytes are the bridge's MAC address.
The iPlex implements the Spanning Tree Protocol in its two Gigabit Ethernet ports. By using this feature, you can daisy-chain a number of units and then con-nect the last unit back to the first (thus forming a ring). The protocol will ensure that one of the links in the ring is held in reserve. If any one link is lost, the ring is patched by turning on the reserve link. Other more complex applications are also possible. The iPlex Spanning Tree Protocol implementation will interoperate with any standard third-party device with similar support.
The iPlex Spanning Tree Protocol support is limited to a single VLAN, which is user-selectable. If you are planning to use this feature and you have defined multi-ple VLANs in your iPlex, please make sure that the physical topology of all the VLANs is the same (at least, as far as the iPlex is concerned). If one of the GE ports is placed in “blocking” state, it will be blocking for all defined VLANs.
NOTEOnly VLANs with both Gigabit Ethernet ports present will be listed because you need more than one for the protocol to be useful.

SCM SoftwareConfiguration
In the SCM Software Configuration page you can decide where the chassis boots from; that is, where the software image resides.
NOTEIf you enter an invalid DNS server IP address, the iPlex will take a long time to respond to Telnet or SSH connections as it does a reverse DNS lookup on the incoming connection. Similarly, the response will be significantly slowed if the DNS server is present but you connect from an IP address that is not registered with it. TAND-BERG Television recommends leaving this field empty unless you must have name resolution (for example, to specify Syslog, NTP, or other addresses as host names).
WARNINGDue to the limited space for logs in the iPlex, the potentially large number of messages that can be generated by this feature, and the fact that logs do not persist across reboots, TANDBERG Television strongly recommends that an external syslog server be used if log persistence is important.

• Guards against broadcast storms.• Allows iPlexes to connect to a primary and backup switch without allowing loopback unicast
traffic.
The basic diagram
Shown below is a basic system diagram.
The basic system works as follows:
• Input A is only directed at one switch at a time.• The GE Ports on the iPlexes output the same Multicast data to different Cisco Switches.• The configuration is currently managed by nCompass.• To avoid the loopback problems, Unicast Forwarding on the GE ports of the iPlexes are
turned off. Devices on the same VLAN but connected on different GE Ports only receiveunicast traffic from a source connected on the same GE Port.
• This configuration supports redundancy (if Input A can be switched between the Primary andSecondary Cisco Switches).

Notification Log There is no user interface to view current entries in the notification log MIB since the notification log is only maintained for use by the management station. The notification log MIB holds a maximum of 250 entries and a minimum of 10 entries. You have to control this parameter using SNMP. Refer to the Network Man-agement & Monitoring Reference Guide for more information.
SecurityConfiguration
The Security Configuration screen shown below allows you to add access to net-works and to enable or disable network contol interfaces.
NOTEThe ability to disable Warning and Info log messages from being sent to the external syslog servers (i.e., the local6 facility) reduces the amount of system messages when external conditions change (e.g, loss of input or table updates). This traffic-reduction feature is beneficial when an Element Management System (EMS) is being used to manage a large number of iPlex systems.
146
iPlex Web Interface User Guide
The security feature consists of the following capabilities:
• Network access list: You can provide a list of networks to the Mediaplex, and the controlport will only respond (via any of the network access methods) to these networks. It willcompletely ignore any packets (including ping) from any other network. By default, the list hasone entry (0.0.0.0/0), which means access is accepted from anywhere. You can enter a list ofup to 10 networks in the format base_network/mask to restrict access.
• Selective disabling of network control interfaces: You can selectively turn on or off thefollowing accesses from the list of allowed networks: Telnet, SSH, HTTP, HTTPS, SNMP, andControl.
• In-band control from GE ports: You can enable or disable the control of the iPlex from theGE ports.
.
Network Access List Network: The IP address of the network that is allowed access.
Netmask: The network mask to be used to determine the network that is allowed access.
Network ControlInterfaces
Enable Telnet: Telnet access will be allowed if enabled.
Enable SSH: SSH access will be allowed if enabled.
Enable HTTP: HTTP access will be allowed if enabled.
Enable HTTPS: HTTPS access will be allowed if enabled.
Enable SNMP: SNMP access will be allowed if enabled.
Enable GE Ports Control: Control from the GE ports will be allowed if enabled.
CASConfiguration
CAS Configuration screen follows. Currently not implemented.
NOTEEnabling In-band Control is a security risk if consumers in general have access to the GE port. The access control passwords still apply, but enabling this reduces the security of the unit. This setting is recommended only for units engaged in backhaul communication over isolated networks. It allows you to control an iPlex through its GE port(s).

Support
The nCompass Configuration screen is accessed as follows: Configuration->SCM->nCompass. The nCompass support includes the following features:
• A status display, nCC, in the GUI top bar.
• A configuration screen for the nCompass interface.
The screenshot that follows shows both features.
The status display is a virtual LED, which indicates in color the following states of nCompass control:
• Grey: this iPlex is not under nCompass control.
• Red: this iPlex is under nCompass control but it currently is unable to communicate with thenCompass server.
• Green: this iPlex is under nCompass control and is active.
• Blue: this iPlex is under nCompass control and is inactive.
Enable Redundancy: Select or deselect the check box and click the Apply but-ton.
This screen has two functions. Use the check box and the Activate/Deactivate button according to the following:
• If an iPlex has been under nCompass control in the past, it will “remember” that fact and willdisable some functions that can interfere with nCompass operation (such as saving theconfiguration file to startup). If the iPlex is no longer managed by the nCompass server, youneed to access this screen and click on the “Deactivate” button.
• If an iPlex is under nCompass device control but is not part of an N:1 redundancy group,uncheck the Enable Redundancy box. This will speed up the operation.

IP Address: Type IP address of ATMInterface.
Subnet Mask: Type subnet mask of ATMInterface.
Forward Received Multicasts: Deselect to disable forwarding. By default, this is selected and forwarding is enabled.
Framing Mode: Select from SONET or SDH frame mode.
ATM Adapter ModeMode Flag: Select from Bridge mode or Router mode.
Default VPI: VPI value for the PVC to be used by default for unicast traffic if no other routes are present.

transmission system for high-speed digital traffic. Employed by
telephone companies andcommon carriers, SONET speeds
range from 51 megabits tomultiple gigabits per second.
NOTEIf you receive a multicast over ATM, by default the multicast packetsare forwarded to the backplane, in addition to being delivered to theUDPIn port you create. If you have many UDPIn over ATM ports, theprocess of receiving, processing the transport stream, sending itout, and sending another copy of the original packets may overloadthe MCM. However, you can turn off the forwarding of receivedmulticasts into the backplane. This needs to be done globally for theinterface (that is, the entire ATMInterface).If you turn this off, the MCM will be able to sustain the traffic for lotsof UDPIn ports and you can readdress them at will. It defaults toenabled because this was the default behavior prior to this feature.This control is the Forward Received Multicasts checkbox, found in the interface configuration screen.

DisciplinesThe iPlex is capable of offering different QoS (Quality of Service) levels to SME-injected traffic. The different QoS levels are “disciplines” applied on a route-by-route basis. iPlex offers the following QoS disciplines.
■ Expedited Forwarding (EF): This discipline is designed for traffic thatrequires guaranteed bandwidth and low-latency. Packets in this traffic class areinjected as soon as possible with a minimum delay. The discipline has oneparameter, a guaranteed bandwidth level. If the volume of traffic exceeds theconfigured bandwidth, the excess traffic is immediately discarded. Because ofthe low-latency requirement for this discipline, section packing is not used. Itis recommended that no more than 10% of a link’s bandwidth be committed toEF disciplines.
■ Assured Forwarding (AF): This discipline is designed for traffic that requiresguaranteed bandwidth, can have occasional bursts, and can tolerate somelatency. The AF discipline has two parameters, a minimum (guaranteed)bandwidth, and a maximum bandwidth. Traffic under the minimum bandwidthis always carried; traffic in between minimum and maximum is carried if thereis available capacity, and traffic over the maximum is immediately discarded.AF traffic may be section-packed depending on the state of the queues.
■ Best Effort (BE): Best-Effort traffic has no guarantees and is carried in abandwidth available basis, after all the compliant AF and EF traffic is injected.BE traffic may starve for bandwidth and suffer arbitrarily large delays. BEtraffic is section-packed as needed.
The SME port allows you to apply specific disciplines to the route. This applies rules to the delivery method of IP traffic. Once you configure SME, the MPE route will display a drop-down menu listing your available options.
NOTEThe user can have up to 64 disciplines per discipline class. When multiple routes are added to the same discipline they share the bandwidth. For example, create an EF class discipline set at 2 Mb/s, and add three routes pointing to this discipline, then the 2 Mb/s limit applies to the aggregate of these three routes. If each route requires 2 Mb/s then you need to create three disciplines set at 2 Mb/s and point each individual route to each discipline.

Overview of Connecting Inputs to OutputsThe iPlex can receive an MPEG/DVB Transport Stream from an input and has various choices for routing the Transport Stream to an output:
• As a program stream containing all table information needed by the program.
• As an element stream containing the table information needed by the element stream.
• As a PID
Stream TypesThe table below shows the type of stream that the iPlex can route via input and output ports. [L] indicates a logical port and [P] a physical port. The SMD logical port is dependent on the physical ASIIn port; likewise, the SME logical port is dependent on the physical ASIOut. A Transport Stream (TS) via TCPIn, UDPIn, and FileIn can receive Data and Section packetization.
The user can send any Transport Stream input via any Transport Stream output. The shaded cells in the table show that ASIIn can decapsulate IP Traffic via SMD; and ASIOut can encapsulate IP traffic via SME. In addition, the shaded cells for native ATMIn and ATMOut logical ports have an association with the physical ATM submodule.
Streams Types Via Input Ports
Stream Types Via Output Ports
IP Traffic The traffic that the iPlexcan encapsulate as MPE
packets. The iPlex can receive IPdata either from a Gigabit
Ethernet interface or from anATMInterface.
SMD (TANDBERG TelevisionMPE Decapsulation) MPEGTransport Stream received
through ASIIn.
SME (TANDBERG TelevisionMPE Encapsulation) Transport
Stream sent out as IP over DVBthrough ASIOut.

Overview of Logical Ports StructureYou can create or delete logical ports. To create a logical port click Configuration > New Port. The details of the port creation vary dynamically according to the port type. The general steps in creating a port are as follows:
1 First, select the Port Type:■ UDPIn/Out ports receive/send data as the payload of UDP packets. You can
receive or send these packets over the Gigabit Ethernet ports over the ASIIn/Out (SMD/SME network interfaces) ports using IP over MPEG Transportpackets (employing Multi-Protocol Encapsulation) or over ATM, using one ofthe IP over ATM encapsulations.
■ Backhaul ports are UDPOut ports that have no association to a specific input,and can receive content from any input in the system.
■ RTPIn/Out ports are similar to their UDP counterparts, but they employ theRTP protocol over UDP; the RTP payload receives/sends the data. RTP issupported over Gigabit Ethernet and over ATM, using one of the IP overATM encapsulations.
■ ATMIn/Out ports receive/send data as AAL-5 PDUs. These are available onlyon ATMInterfaces.
■ FileIn ports spool the contents of a typically small file residing on the iPlex’sinternal Flash through a previous data file download.
■ TCPIn ports receive the data over a TCP connection, coming either from theGigabit Ethernet port or from TCP/IP over ATM.
2 You must configure additional parameters depending on the type of port.However, one parameter is always present; that is, the port location (shown inthe user interface as Input Blade or Output Blade). Ports always have anassociation with an MCM.
PacketizersPacketizers convert the data received from an input port to a flow of transport packets suitable for further processing by the iPlex. There are three types of pack-etizers:
• Data Pipe: This packetizer complies with ETSI EN 301 192 section 4. Essentially, thereceived data becomes the payload of the transport packets. You can optionally configure thispacketizer with a timeout; after the timeout, a partially-filled transport packet will contain anadaptation field to complete the payload.
• Section: This packetizer expects private section as defined by ISO/IEC 13818-1. It performssome section syntax checking.
• M2T: This packetizer is a “pass-through” for data that is already in MPEG-2 Transport packetformat. Additionally, it checks sync bytes for correctness.

Output Stream ConfigurationAll output ports provide the same configuration options in regards to the stream type. The two output types are MPEG and DVB. MPEG streams only have PAT and PMT; for DVB streams, you can add NIT, SDT and TDT. You can also enable or disable the CAT.
iPlex InterfaceNaming
Convention
There are two port types in iPlex: physical and logical. The discovery of physical ports occurs as part of initial submodule discovery. Logical ports are created by user.
The naming convention for physical ports (submodules) is as follows: Port-TypeSlotNumber/UnitNumber.
The naming convention for logical ports is: PortTypeSlotNumber/Num-berUsed.
UnitNumber andNumberUsed
In physical ports, the unit number starts with 0. Each submodule slot on an MCM contains two unit numbers with a range from 0 to 15. In logical ports, the user assigns the number and has no range.
MCM Example You may, for instance, have one ASI input, an Encoder, an ATM, and ASI output. Since each ASI submodule has two ports, you have two available inter-faces; however, encoders and ATM submodules have only one interface per submodule. The names for this blade would be as follows: ASIIn1/0 and ASIIn1/1, ENC1/2, ATM1/4, ASIOut1/6 and ASIOut1/7.
The ASI input port creates a SMD (TANDBERG Television MPE Decapsula-tion) interface. The SMD interface associated with ASIIn1/0 will be smd1/0 and the ASIIn1/1 will be smd1/1. The ASI output creates a SME (TAND-BERG Television MPE Encapsulation) interface. The SME interface attached to ASIOut1/6 will be sme1/6 and the ASIOut1/7 will be sme1/7.
Additionally, the user can create UDP logical output port with unit number 0, and receive the name UDPOut1/0. Logical ports include: UDPIn/Out, RTPIn/Out, FileIn, and TCPIn.
SCM Example Each SCM blade has two Gigabit Ethernet interfaces: GE1 and GE2.

Screen Navigation ButtonsAt the top of many of the Configuration and Statistics screens there are buttons (links) like the ones displayed below.
Active (in effect) buttons are blue and inactive buttons are grey. The buttons are:
171
iPlex Web Interface User Guide
Mode: Placing the cursor on this button takes you to the Statistics page of this port if you are viewing the Configuration of it and vice versa.
Redundancy: Placing the cursor on this button takes you to the Redundancy chassis screen if redundancy is enabled or takes you to the Primary chassis if you are viewing the Redundancy page.
Navigation: Provides navigation (Next and Previous) through the list of ports or interfaces. See more details in the “Navigating through Ports/Interfaces” below.
Go: Placing the cursor on this button takes you to the:
• Advanced version of the current screen• Media Routes screen.• Media Routing screen.
For the Encoders, the Go button navigates to the Advanced and Media Routes screens and to the Audio screen with further navigation to Channel 1 through Channel 6 or 8 (for single-slot encoders). For AVC Encoders the button also nav-igates to the PIP page.
Navigatingthrough Ports/
Interfaces
You can easily circulate through ports or interfaces. The navigation through ports/interfaces varies depending on an entry point: the navigation follows the port/interface type from where the user arrives to the port/interface page.
For example, the following ports are in service:
• ASIIn1/0
• ASIIn1/1
• ASIIn1/2
• ASIIn1/3
NOTEThe buttons will be displayed on the screens that use navigation. The buttons may differ depending on the screen navigation needs as shown in the example above.
172

• ASIOut3/1
• ASIOut3/2
If you select Ports ->ASIIn ports ->ASIIn1/0, the Previous (<--) button points to ASIIn1/3, and the Next (-->) button points to ASIIn1/1.
If you select Ports ->Physical ports ->ASIIn1/0, the Previous button points to ASIOut3/2, and the Next button points to ASIIn1/1.
Backing Up the Configuration File
NOTEBefore making any changes to your system, TANDBERG Televisionrecommends that you save the current state of your system bycopying the currently running configuration file to a backup file (youchoose the name of the file) in order to be able to go back to thecurrent configuration should you ever need to do so. See CopyRunning on page 123 for the procedure on how to do this.After you change your system and are confident everything isworking correctly, TANDBERG Television recommends that youcopy the configuration file at that point to the startup file in order tohave a known starting point should the system ever have to reboot.See Copy Startup on page 122 for the procedure on how to do this.

Physical Input Ports: ASIInThe physical input ports are submodules installed on the iPlex. iPlex has two: the ASIIn and the Encoders. These ports are automatically created when the submodules are installed on the iPlex.
ASIIn configuration is explained in the following section. Encoder configuration is explained in the Encoder sections, Physical Input Ports: Encoders.
Configuring ASIInThe ASIIn Configuration page enables you to configure ASI input interfaces. Since this is a physical device, it is automatically created by the system for the ASI input submodules present in your chassis. To set it up, select Configuration from the menu. In the menu, you can find the ASIIn configuration page under either Ports or the MCM.
After completing the configuration, click Apply.
For information on using the buttons at the top of the screen, see Screen Naviga-tion Buttons on page 171.
Interface ASIIn I/O Description: Enter an arbitrary description string (a label) for this port. This has no influence on iPlex operation.
Channel Active: ASI input ports have two physical inputs, Input A and Input B. Use this control to select which one is active.
Enable Traffic Shaping: Check the box to enable or disable traffic shaping.
NOTEThe physical Network ATM port configuration and statistics can be found in Chapter 3, Using the Web Interface.
GI (General Instruments) refers toDigiCipher II (DCII): a proprietary
MPEG-2 based distributionsystem developed originally by
General Instruments prior to thecompletion of the DVB standard.Used by most cable channels in
North America, it has a majorpresence in cable head-ends and
is widely used in satellite turn-around applications via “Head-
end In The Sky” (HITS) systems.

iPlex Web Interface User Guide
.
Traffic ShapingBy default, the iPlex processes the transport packets from ASI inputs in batches. In some situations, this can cause excessive burstiness if the content from this ASI port is routed to a network output. This problem can be solved by enabling traffic shaping for the ASI input. The screenshot that follows shows the location of this control. This feature is recommended for the following situations:
• A low bit rate ASI Input (typically with a single program in it) routed to a network output port.
• An ASI Input that is fully routed (all programs) to a network output port.
This feature is not necessary in the following situations:
• When content from the ASI Input is routed to an ASI Output.
• When content from the ASI Input is routed to an ATMOutput (either ATMOut or UDPOutover ATM) and ATM traffic shaping is enabled.
• When there are multiple programs in the ASI Input, and each program is routed to anindividual network output port.
Transport Stream Enable Table Forwarding: Select the check box to enable table forwarding. By default, the iPlex detects, processes and forwards to the output any (P)SI table changes coming from the input. If this behavior is not desirable, clear the check box to disable it.
Input Stream Type: Select from the following: MPEG, DVB, ATSC, or GI. Your selection must match the actual incoming stream. This control selects the type of parsing that is performed on the input stream. The retrieved information is found in the Statistics screen for the port.
Enable SDT Parsing: Select for SDT parsing. This will give you channel names if the SDT is present.
Enable NIT Parsing: Select for NIT parsing. This will give you tuning informa-tion for the network if the NIT is present.
Enable CAT Parsing: Select for CAT parsing. This will give you the EMM PID and CA System ID if the CAT is present.
NOTEEnabling this feature will cause increased CPU utilization in the MCM and may result in an overall reduction of system capacity.
NOTESelecting DVB for Input Stream Type gives you two additional check boxes to enable SDT and NIT parsing.

Interface ENC Description: Enter an arbitrary description string (a label). This has no influence on iPlex operation.
Encoder Started: Select check box to enable encoder operation.
Video Format: Select type of video format: PAL, NTSC, or NTSC without pedes-tal.
. Video Resolution: Select video resolution in NTSC and PAL from the following: 720x480(NTSC):576(PAL), 704x480(NTSC):576(PAL), 640x480(NTSC):576(PAL), 544x480(NTSC):576(PAL), 480x480(NTSC):576(PAL), 352x480(NTSC):576(PAL), 528x480(NTSC):576(PAL).
Encoding Method: Select encoding method as VBR, CBR (ES), or CBR (TS).
Variable Bit Rate (VBR): The Transport Stream (TS) will have a Variable Bit Rate (VBR). The bit rate of the TS will never exceed the maximum bit rate selected and it will fall to lower rates whenever possible, consistent with the selected video and audio quality settings and the complexity of the audio and video streams being encoded.Recommendation: This setting is recommended for higher bandwidth access networks (for example, FTTH) where busting to high rates is tolerable and desir-able for maximum video and audio quality but constant padding to the maximum rate would be unacceptably wasteful..
Constant Bit Rate:
• Constant Bit Rate – Elementary Streams (CBR-ES): The video Elementary Stream (ES)will have a Constant Bit Rate (CBR). The Transport Stream, of which the video ES is onecomponent, will be somewhat VBR when audio and other overhead is added.Recommendation: This setting is recommended for lower bandwidth access networks (forexample,. DSL). This setting seeks to constrain the Transport Stream bit rate to a tight range,while simultaneously minimizing network overhead.
• Constant Bit Rate – Transport Stream (CBR-TS): The Transport Stream (TS) will have aConstant Bit Rate (CBR).Recommendation: This setting is recommended for network operators who want tosimultaneously transmit the live stream and record it for later playback on a video server (asmost video servers require CBR Transport streams). The rate control is designed to maintain aconstant Transport Stream bit rate across the network including servers. CBR-TS does not useNull-packet padding to achieve the bit rate, because most video servers will discard the Null-packets.
TIP NTSC without pedestal is avariant of NTSC used primarily in
Japan. For U.S. sources, selectNSTC.
NOTEIf VBR is selected, a VBR Bit Rate section appears with the average bit rate and a peak bit rate parameters. If CBR is selected, it is only necessary to specify a bit rate.

Encoder AdvancedSettings
This section provides more detailed explanation of the Encoder Advanced param-eters.
GOP SizeThis parameter specifies the number of frames (pictures) in a GOP (Group of Pic-tures). A typical GOP structure starts with an I-frame and ends with a B-frame with a frame sequence like IBBPBBPBBPBBPBB. A bigger GOP size in slow
NOTEPrograms only have one PCR. Thus, an additional PCR will not be referenced in the PMT.

motion pictures may give better quality at lower bit rates. This value increments by three with a range of 6 to 30 frames; the default is 15.
Analog Decoder Preprocessing ControlThese parameters provide complete control over video processing for input analog video using composite and Y/C input channels.
Luminance Filter Control
This is the sharpness control and allows you to select the correct luminance filter characteristics. The encoder supports a variety of filters to provide the most flexi-bility to get the best image sharpness at different frequency ranges. There are three basic types of filters:
• Luminance Peaking Filter: These filters allow the resolution enhancements peaking at 4.1MHz. You can choose from the following gain levels: 8.0/6.8/5.1/4.1/3.0/2.3/1.6 dB.
• Plain Response: Select this option disable any luminance gain/reduction.
• Low Pass Filter: The low pass filters can reduce the luminance for the range of frequencies.Five filters reduce luminance with maximum reduction at 4.1 MHz. The supported reductionlevels are 2.0/3.0/4.0/8.0/14.0 dB.
Chrominance Gain ControlYou can control the gain on the color component of analog CVBS or Y/C video. The range is 0-63 (0.5 dB to 7.5 dB) on logarithmic scale where 36 represents the gain of 1.125 dB and 63 represents 7.5 dB gain. Zero (0) is the default and sets the analog decoder chip to automatically control the gain.
Brightness ControlThe range of 0-255 represents dark to complete brightness. The resolution of brightness changes with respect to the full luminance range. The default is ITU-601/656 recommended value of 128.
Contrast ControlThis parameter controls the luminance contrast gain for input analog video. The value multiplied by the luminance value provides contrast adjustment. Contrast is the luminance gain. The provided range is 0-127 where:
• 0 represents no-luminance gain.
• 63 represents gain of 1.0 dB.
• 67 default- ITU-601/656 recommended value of 1.063 dB.
• 127 represents maximum gain of 1.984 dB.
Y/C: A shorthand term used forluminance (Y) and chrominance
(C). Also used to describe S-Video, which implies the
separation of the luminance andchrominance parts of a video.
CVBS (Composite VideoBlanking Sync): This video signal
has the color, luminance andsynchronization information all
combined into one.
dB: Decibel, a logarithmic unitused to describe a ratio.
195
iPlex Web Interface User Guide
Chrominance Saturation
Chrominance saturation ranges from 0 to 1.984 dB with default at 1 (ITU-601/656). The saturation is the Chrominance (U) and Chrominance (V) gain. You can use this value to add a gain adjustment to the U and V components of the input video signal. Both U and V components adjust by the same amounts.
Chrominance HueChrominance Hue ranges from 0-360 and internally maps to -180 to +178.6 with the default set to 0. The hue adjustment involves the addition of a number, in two’s complement format, to the demodulating sub-carrier phase.
Scaler Prefilter Controls
These parameters provide complete control over the processing required for downscale of video input. You can adjust the settings for both analog video input and digital video input (SDI).
The prescaling function inside the encoder consists of an FIR (Finite Impulse Response) anti-alias filter stage and an integer prescaler, which creates an adaptive prescale dependent low-pass filter to balance sharpness and aliasing effects. The FIR prefilter stage implements different low-pass characteristics to reduce alias for downscale in the range of 1 to 1 ½.
Prefilter Luminance ControlThis parameter controls the low-pass FIR filter characteristics for luminance com-ponent for anti-aliasing purposes. There are four different characteristics to choose from:
• Bypass: To completely bypass the FIR filter.
• Low: For a smooth response over the spectrum. This filter provides 12 dB reduction at 4.75MHz.
• Medium: This filter provides 12 dB reduction at 3.5 MHz.
• High: This filter provides 12 dB reduction at 2.75 MHz.
Prefilter Chrominance ControlThis parameter controls the low-pass FIR filter characteristics for the chrominance component for anti-aliasing purposes. There are four different characteristics to choose from:
• Bypass: To completely bypass the FIR filter.
• Low: For a smooth response over the spectrum. This filter provides 12 dB reduction at 2.25MHz.
• Medium: This filter provides 12 dB reduction at 1.5 MHz.
• High: This filter provides 12 dB reduction at 1.25 MHz.
Chrominance (U): A colordifference signal constructed bysubtracting the blue from the Y
(luminance).
Chrominance (V): A colordifference signal constructed by
subtracting the red from the Y(luminance).
SDI (Serial Digital Interface):Used to transport digital
component video.

Prescaler Brightness GainThis parameter controls luminance brightness of input digital video or analog video before scaling. The range of 0-255 represents dark to complete brightness. The resolution of brightness changes with respect to the full luminance range. The default is the ITU-601/656 recommended value of 128.
Prescaler Contrast GainThis parameter controls the luminance contrast gain factor for input digital video or analog video before scaling. The value you specify here, divided by 64 gives the multiplier gain factor for the output contrast. The provided range is 0-127.
Prescaler Saturation GainThis parameter controls the chrominance saturation gain factor for input of digital video or analog video before scaling. The value you specify here, divided by 64 gives the multiplier gain factor for the output saturation value. The provided range is 0-127.
Noise ReductionFilters
There is a built-in noise reduction engine, just before the compression step, used for analog as well as digital video inputs. These noise reduction filters can greatly improve the efficiency of compression as they can utilize the bandwidth for higher quality rather than encoding undesired noise.
Spatial Linear FilterThis filter can be either in static or dynamic mode. You can set the filter into static mode to directly control the filter level. As well, you can set the filter to one dimensional or bi-directional for both the luma and chroma components sepa-rately.
Spatial filter analyzes the surrounding picture content and can remove impulse (or speckle noise) within content.
Spatial Median FilterThis filter selects a median value of the luma and chroma separately to replace the original value. The search window can be horizontal, vertical, both horizontal and vertical, or diagonal. You can set values to both luma and chroma separately.
FilterThis filter can also be static or dynamic. You can set this to static mode to control the filter level directly. The temporal noise filters exploit the temporal redundancy of progressive video frames and the image is effectively averaged across multiple frames such that the noise is averaged out. Temporal filtering can be especially effective for pictures, which have little motion.

Spatial Filter Auto ModeThe default setting for spatial linear filter is dynamic (automatic). To control the filter level statically, you should deselect this box.
Spatial Filter LevelOnce you change the spatial filter mode to static (non-automatic) this field will H.264appear, and you should set the filter level between 0-15.
Temporal Filter Auto ModeThe default setting for temporal filter is dynamic (automatic). To control the filter level statically, you should deselect this box.
Temporal Filter LevelOnce, you change the temporal filter mode to static (non-automatic), this field will appear, and you should set the filter level between 0-31.
Median Filter TypeThis parameter controls the spatial median filter settings. You can select one of the following options:
• Disabled: Spatial median filter disabled.
• Horizontal: Search window is horizontal.
• Vertical: Search window is vertical.
• Horizontal and Vertical: Search window is both horizontal and vertical.
• Diagonal: Search window is diagonal.
High and LowThreshold Settings
The values set for the high and low fields listed below work in conjunction with each other. For example, a high setting of 150 enables 150-255 and a low setting of 100 enables 0-100 therefore the values 100-150 are filtered out.
Luminance High ThresholdThis controls the threshold above which median filter enables luminance. This will range between 0-255 with default to 0.
Luminance Low ThresholdThis controls the threshold below which median filter enables luminance. This will range between 0-255 with default to 255.
Chrominance High ThresholdThis controls the threshold above which median filter enables chrominance. This will range between 0-255 with default to 0.

Enable Safe Area Blanking: Select to enable. The safe area blanking function is performed on the uncompressed video data before it enters the encoder. When enabled, the safe area blanking causes all video samples outside of the safe action area to be forced to black level.
Enable Half Frame Rate: Check the box to enable or disable half frame rate.
Video Preprocessing The spatial filter employs a non-linear filtering technique and conditions the video signal before it is encoded. This allows the video encoder to more effi-ciently code the overall picture by selectively reducing the entropy of the video signal before encoding it.
Enable Spatial Filter: Check the box to enable or disable the spatial filter. The spatial filter is turned on by default for your use in the following circumstances:
• The video encoder is being used in low bit rate applications.
• The incoming video signal is especially noisy.
This type of filter is not only useful for its noise reduction properties, but also for its ability to improve the compression quality in generalized content while mini-mizing the impact on subjective quality. This improvement is especially true in comparison with conventional spatial filtering techniques (such as median, Gauss-ian).
A side effect of the filter is that it will remove some of the detail in the picture. This loss of detail will appear as a flattening or softening in certain areas of the image. So using the filter is a trade-off between loss of image detail, improved compression efficiency, noise reduction properties, and improved quality and com-pression ratio for noisy input signals.
Because the noise has created a lot of unnecessary entropy information in the video for the encoder to handle, the optimal solution is: in addition to noise reduc-tion, the detail loss due to noise filtering by the spatial filter will be no worse than the loss of picture detail due to the inherent distortion of the encoder so that the effect of using the spatial filter on system performance will be negligible.
Spatial FilterParameters
Strength: Set the spatial filter strength; range: 1 - 128; default: 6. When tuning the filter, use the following procedure:
Leave the passes value at 3 (see below). Do not change that value unless directed by TANDBERG Television.
The strength value controls the trade-off between improved compression effi-ciency and loss of detail in the image. The higher the strength value, the more fil-tering is achieved with a corresponding loss of detail. The best value will be found empirically and subjectively by adjusting the filter and then looking at the result. TANDBERG Television recommends that you start at around 4 and slowly increase the value until you achieve the desired quality. In most cases, the best value will be somewhere between 4 and 12; but overall, this conclusion depends on the video resolution and target bit rate.
Passes: Set the spatial filter number of passes; range: 1 - 3 (default: 3; leave at default unless directed by TANDBERG Television).

iPlex Web Interface User Guide
Luminance Filter: Select the value for the luminance filter. The luminance response may either be rolled-off or boosted in four steps from -1dB through -5dB and from +1dB through +5dB as measured near the high end of the fre-quency range. By default, a flat frequency response is provided. This filter may be used alone or in conjunction with other preprocessing filters.The luminance enhancement function provides a linear filtering process that permits an adjustment to the luminance frequency response. It is performed on the uncompressed video samples prior to encoding. Reduction of high fre-quency components generally improves encoding efficiency but at the expense of some loss in image detail. The boost settings may be used to restore high frequency components lost in analog video interfaces or during transmission.
Analog VideoPreprocessing
Types of analog video signals:
• Y/C: A shorthand term used for luminance (Y) and chrominance (C). Also used to describeS-Video, which implies the separation of the luminance and chrominance parts of a video.
• CVBS (Composite Video Blanking Sync): This video signal has the color, luminance andsynchronization information all combined into one.

MPEG-4 AVC Ultracompression HD Encoder (AVCEnc HD) General Configura-tion and Statistics
Overview MPEG-4 AVC Ultracompression Encoder is capable to compress video more effectively than other encoders and to provide more flexibility for application to a wider variety of network environments. This is a dual-slot encoder.
The MPEG-4 AVC Ultracompression encoder offers two factory-installed input interface options:
• HD-SDI Interface: this interface only supports digital uncompressed video. It can beconfigured to accept either HD-SDI or SD-SDI inputs. See more, HD Encoder on page30.
• SD Interface: this interface only supports standard definition video signals, both analog(composite and s-video) and digital (SD-SDI). See more, SD Encoder on page 31.
Both interfaces support embedded audio in the digital interface, as well as analog balanced or unbalanced audio. They also support digital AES audio.
AVCEnc is a logical name of the MPEG-4 AVC Ultracompression Encoder, HD or SD.
AVCEnc HDGeneral
Configuration
The MPEG-4 AVC Ultracompression Encoder General Configuration page enables you to configure the AVC Encoder interfaces. Select Configuration from the menu. You can find a list of these encoders under either Ports or the appropri-ate MCM blade.

The parameter fields are as follows.
Description: Enter a description or label for this encoder, 0 to 79 characters (optional).
Video Source: Select from the drop-down list an HD input: Off, HD-SDI, Color Bars, Black, or SD-SDI.
HD-SDI VideoSource
HD Input Format: This parameter shows up as HD Input Format if Video Source selected is Off, HD-SDI, Color Bars, or Black. Select from the drop-down list a video input format: the 1080i number of lines over 25 or 29.97 FrameRates correspond to the HD (high definition).
OP Video Loss: Output Video Loss options depend whether the cable is con-nected or not. Select from the drop-down list the type of an output video loss: Freeze Frame (the last frame is repeated), Black, or Bars (color bars).
Clarus Noise Reduction: This feature is available if it is provided under the license. Select from the drop-down list: Off (if you choose not to use this feature), or Adaptive 1 through Adaptive 4, or Fixed 1 through Fixed 3.
Clarus Deblocking: Check the box to enable or disable Clarus deblocking filter.
215
iPlex Web Interface User Guide
Clarus Input Deblocking Filter
This is an input deblocking filter that operates on previously encoded data. It automatically detects macroblocks and attempts to clean up the edges.
Resolution 1080: Select from the drop-down list a value of the video resolutions for the 1080i input video (HD): 960, 1280, 1440 04 1920 by 1080 HD resolution.
Mode: Select from a drop-down list a bit rate mode for the video encoder: a Stan-dard (Max 3.0 s), Low Delay (Max 1.5 s), Mega Low Delay (0.75 s), or Seamless Variable Delay.
Mega Low Delay mode
This delay mode uses an even shorter delay and smaller decoder buffer size thaneither the Standard or Low Delay modes, which helps shorten channel changetime, but at the expense of reducing video quality. In this mode, the only GOPstructure supported is IP (no B frames), and there are no hierarchical B frames.
Seamless Variable Delay mode
Unlike the other fixed delay modes (such as Standard, Low Delay, Mega LowDelay), seamless variable delay (SVD) mode provides flexibility in choosing delaysand decoder buffer size. The decoder buffer size is calculated as minimum bitrate xdelay (each of which are user parameters), up to 15 Mb for HD or 10 Mb for SD.
Also, in SVD mode, the video bitrate can be changed on the fly without requiringan encoder restart.
Finally, SVD mode is necessary to enable VBR (Variable Bit Rate) operation.
Video Bit Rate (bps): Enter the bit rate per second at ES (Elementary Stream) level; the range is 250 000 bps - 20 000 000 bps. For HD video source, the bit rate range is 1 000 000 to 20 000 000 bps.
VBR Operation
In VBR mode, the encoded video bitrate can vary over time between theminimum bitrate and maximum bitrate, depending on the complexity of thesource material. The target quality parameter affects the video quality as well asthe average VBR bitrate. The higher the number, the higher the average VBR rate.If VBR is available, the following four parameters appear:
VBR Mode: Click a radio button to turn OFF the VBR Mode (returning to default CBR) or turn it On (No Stuffing).
Seamless Delay (sec): Enter the value for seamless variable delay (0.5 - 4.0 sec-onds); float format: xx.xxxx.
Minimum Seamless Bit Rate (bps): If VBR mode is selected, this is the mini-mum bitrate; the range is 250 000 bps - 20 000 000 bps.
Target Quality (%): Appears only if VBR mode is selected and affects the aver-age bitrate. Enter the value; the range is 30% - 100%.
NOTEVBR is a licensed feature.

The Codec transitions between the two channels above seamlessly (except possibly for a signal level discontinuity) and without a restart.
Dual Mono SplitSome legacy systems use the “Dual Mono” mode available in AES and some audio encoders to implement support for multiple languages. A Dual Mono signal is just like a stereo signal, but instead of having a left and right channel, it has two inde-pendent mono channels (typically different languages). A receiver must play out only one of them, as selected by the user.
In modern systems, it is usual to run different languages in separate PIDs. In fact, some of the newer audio CODECs do not support this mode. The encoder has the ability to read the Dual Mono signaling on an incoming AES (or SDI embed-ded) audio signal and split the dual-mono feed into two independent feeds. To accomplish this, feed the audio source simultaneously to two audio encoders (for example, Audio 1 and Audio 2) by selecting the same audio source. Then, check the Enable Dual Mono Split box to activate this feature in both audio encoders. Finally, select the Replicated Channel as Channel 1 for one encoder, and Chan-nel 2 for the other.
If configured as above, the system will operate as follows: if the incoming signal is Stereo, it will be simply replicated into the two audio channels (that is, they will have identical content). If the incoming signal switches to Dual Mono, each encoder will take only one channel, as configured. The encoded bitstream will still be stereo in each PID, but the left and right channels will be the same.
Audio Digital Gain Ch1: Enter the value within the range -12dB to 12dB; the default is 0dB.

Both the Interface AVCEnc x/x and Encoder Service Information sections are the same as such sections for the AVCEnc HD (see page 230) with the Betty Removal support instead of Enable CC corresponding to the SD Input Format of 480i/29.97. In addition, the SD mode also provides Aspect Ratio parameter.
Betty Removal: Check the box to enable Betty filtering. The filter should be enabled in cases where Betty data services are present and should otherwise be left disabled.
Betty TV supports a proprietary method of transmitting data services within the active video area. In such a system, digital data is encoded near the borders of the video frame in areas that are normally not visible on an overscanned television monitor. If present, the data services information may adversely affect the video compression performance of the encoder. In order to alleviate this problem, the encoder supports an optional Betty Removal filter, which is specifically designed to blank the portions of the image carrying the encoded data.
Aspect Ratio: Click a radio button to select 4:3 or 16:9 Aspect Ratio. The aspect ratio of an image is its width divided by its height. Two common videographic aspect ratios are 4:3, universal for standard-definition video formats, and 16:9, uni-versal to high-definition television and European digital television.

MPEG-4 AVC Ultracompression (Single Slot) Encoder General Configuration and Statistics
Overview In addition to the dual-slot MPEG-4 AVC Ultracompression Encoder, there is a single-slot MPEG-4 AVC Ultracompression Encoder which fits in a single PMC slot. The advantages for the single-slot encoder are:
• Fits in a single slot, so 8 of them can be fitted in one iPlex chassis.
• Improved video quality compared to the dual-slot encoder.
• Up to 8 audio channels can be encoded by each card.
The MPEG-4 AVC Ultracompression encoder offers two factory-installed input interface options:
• HD-SDI Interface: this interface only supports digital uncompressed video. It can beconfigured to accept either HD-SDI or SD-SDI inputs. See more, HD Encoder on page30.
• SD Interface: this interface only supports standard definition video signals, both analog(composite and s-video) and digital (SD-SDI). See more, SD Encoder on page 31.
Both interfaces support embedded audio in the digital interface, as well as analog balanced or unbalanced audio. They also support digital AES audio.
AVCEnc is a logical name of the MPEG-4 AVC Ultracompression Encoder, HD or SD. In the following sections, this single-slot encoder is referred to briefly as AVCEnc Single HD or AVCEnc Single SD.

iPlex Web Interface User Guide
Logical Input PortsMost logical input port configurations seen in this chapter use Gigabit Ethernet interfaces. However, when using Network Interface an additional port parameter displays: the ATM Port Association. For most examples, the M2T packetizer is used as the data type, which allows the user to select the input stream type as DVB or MPEG. Network input ports (UDPIn, TCPIn, and RTPIn) receive their data from IP packets. Generally, IP packets can have unicast or multicast destination addresses. For proper operation of the input port, you must exercise care to ensure the deliv-ery of IP packets. In the case of unicast packets, this may impose additional requirements in the data source and in the network infrastructure surrounding the iPlex. The following paragraphs describe the special considerations for the cases of IP packets delivery.
Unicast traffic delivered over ATM: Send packets to the IP address assigned to the ATMInterface, in the appropriate PVC.
Multicast traffic delivered over ATM: No special requirements. iPlex will join the specified group and will respond to IGMP group memberships requests. You must specify the appropriate PVC.
Unicast traffic delivered over Gigabit Ethernet: This is the most restrictive case. Each MCM has an internal backplane IP address, and unicast packets should go to this address. Moreover, the underlying network connected to the iPlex needs to route these packets properly. More specifically, follow these steps:
1 Configure the data source to send the traffic to the internal backplane IPaddress of the blade where the user created the port. This address is in theport statistics page.
NOTES1. Most Classical IP over ATM implementations do not supportmulticast (although the iPlex does), so this may not work in RouterMode.2. As the chassis receives multicast packets over ATM, by default those packets are forwarded to the backplane, in addition to being delivered to the UDPIn port that is listening to them. This is done to have these packets available for further routing, as required. How-ever, if many such ports are created, the process of receiving, pro-cessing the transport stream, sending it out, and sending another copy of the original packets may overload the MCM. In these cases, you have the option of turning off the forwarding of received multi-casts into the backplane, thus leaving more processing power avail-able for additional ports. This is done globally for the interface (that is, the entire ATMInterface). This control is the Forward Received Multicasts checkbox, found in the interface configuration screen. See Interface ATM on page 151 for a description of this control.
290
iPlex Web Interface User Guide
2 Deliver the actual packets to one of the iPlex Gigabit Ethernet ports. Youshould configure this port as part of a VLAN.
3 Configure the IP address of one of the Gigabit Ethernet VLANs as the next-hop gateway for the blade IP address, either in the data source or in the routerconnected to that VLAN.
Blade IP addresses default to the 172.17.1.0/24 range, which is one of theprivate ranges defined in RFC 1918. If that conflicts with your network, youcan reconfigure the backplane address.
Multicast traffic delivered over Gigabit Ethernet: One of the parameters in the port creation is the VLAN (only for UDPIn and RTPIn; TCPIn does not support multicast). The network infrastructure must deliver the multicast packets to any ports in the selected VLAN. The iPlex will respond to IGMP queries for the address.
Unicast traffic delivered over ASI: For UDPIn ports over ASI (that is, ports receiving UDP packets carried over MPEG), you must send the packets to the IP address of the SMD interface associated with it. Also, the packet’s destination MAC address must match the interface’s MAC address, and you must configure the SMD interface to listen on the appropriate PID.
Multicast traffic delivered over ASI: Similar to the previous case, but without the need of matching the destination address. You must configure the SMD inter-face to listen on the appropriate PID.
Other logical input ports include FileIn (files present in the iPlex and spooled) and ATMIn (data received over Native ATM on AAL-5 PDUs).

IP Address: Shows the target IP address to which you should direct the stream.
NOTE ON TCPIn PORTS OVER ATMThe TCPIn port supports operation over ATM. Since the TCP protocol itself does not support multicast operation, the TCPIn port over ATM will use whatever PVC is configured for unicast traffic for that particular physi-cal port. The exact details of this operation are a function of the mode set for the ATM adapter (routed or bridged), as follows:—If the ATM adapter is in bridged mode, all TCP traffic will use the default PVC. Since the iPlex does not support the concept of a next-hop gateway in bridged mode, in practice this limits TCPIn external endpoints (i.e., data sources) to the subnet defined for the ATM adapter.—If the ATM adapter is in routed mode, the TCP traffic will use the ATM routing table. Packets will use whatever PVCs are defined to reach the destination subnetwork, or the default PVC if there is no specific route.

ConfiguringExternal Data
Sources toConnect to the
iPlex
External data sources that provide TCP data must be configured to connect to the internal backplane address of the blade where the port has been created. This is the field displayed in the “IP Address” field of the TCPIn statistics page.
IP Tunneling forTCPIn Port
The iPlex accepts incoming TCP connections to a specified port. Once the con-nection is established, the iPlex expects that the TCP bitstream will contain Layer-3 IP packets. These packets are then converted to MPEG transport packets using the Multiprotocol Encapsulation defined in ETSI EN 301 192. If the iPlex does not recognize IP packets in the bitstream, the connection is forcefully dropped.
To create a TCPIn port with the IP Tunneling packetizer:
1 In the Configuration menu, click New Port.
2 Select TCPIn as the port.
3 Enter the port number.
4 Select the input blade.
5 In the data type list, click IP Tunneling.
6 Click Create.
NOTEThe data source or the network infrastructure must contain a route for this IP address, with the desired SCM gigabit port as the next hop gateway. Please see the “Logical Input Ports” section found on page 290.
NOTEThere are no standards for tunneling IP packets over a TCP connec-tion. To use this feature, you must have an application that has been designed for it: either a custom application that you have written or TANDBERG Television’s zBand Server.

The following additional statistics for IP Tunneling are available:
• IP Packets Generated: Shows the number of IP packets generated and forwarded.
• IP Packets Discarded: Shows the number of IP packets that are discarded because they areinvalid (wrong IP header checksum, or wrong IP version - only IPv4 is supported).
• Bytes Dropped: Number of bytes dropped before finding a valid IP Datagram.
NOTETCP connections are forcefully dropped if no IP packets are found; these statistics will display the number of bytes read from the con-nection and then discarded.

Routing TCPInData to One or
More OutputPorts
Once the selected port is receiving data, the resulting transport packets must be routed to one (or more, if you wish) output ports. TCPIn data with the IP Tunnel-ing Packetizer is typically routed to an ASI Output port, but there are no restric-tions - you can route it to any output port. Since there are no tables associated with this input, you will need to use a stream route.
NOTEIt is your responsibility to ensure that the output port has enough bandwidth to accommodate the stream.For example, if you are routing a TCPIn port to an ASI Output, where the available bandwidth is only 2 Mb/s, turn on TCP flow con-trol in the port and set up a maximum of 2 Mb/s, thus ensuring that all the packets are injected. If you try to inject more packets than available bandwidth, transport packets will be dropped in the output port, even though TCP ensures that they are properly delivered to the input port.
NOTEIt is recommended that, if at all possible, the TCPIn port be located in the same blade as the intended output, to optimize backplane routing.

RTP Link Reliability Link Reliability: Select None, Retransmission, or FEC from the drop-down box. Packets transmitted over an IP network may drop in transit for a variety of reasons. The RTPIn/Out ports have provisions to try to recover from these packet losses. The provisions are as follows:
• None: No recovery provided.
• Retransmission: If the receiving port detects packet loss, it will request a retransmission. Ifthe sender still has the original packet it will re-send. RTCP Negative Acknowledgementmessages defined in the H.261 RTP profile, RFC 2032, request retransmission.
• FEC: The sender transmits additional packets used to reconstruct the lost data. The protocolused is the RTP Generic Profile for Forward Error Correction, RFC 2733.
Received Buffer Size Received Buffer Size: Enter the received buffer size, in packets. This buffer is used for resequencing packets if they arrive out of order. Also, if you select Link Reliability as “Retransmission”, this buffer is used to hold the data until the retransmitted packet is received. In that case, you should set this buffer to an amount of packets at least equal to the round-trip delay of your network.

Logical Output PortsLogical output ports always have an association. If the intention of this port is to output over Gigabit Ethernet, its logical association is with an input port (UDPIn, Backhaul, RTPIn, ASIIn, ATMIn, or Encoder). This logical association gives a “limit” to the iPlex as to which input port will provide the data for routing so that the iPlex can optimize its internal routing. If the intention of this port is to output over ATM, then its logical association is with the particular ATM submodule it will use—these ports have no input restrictions. ATMOut ports are an exception in the sense that they always have an association with an ATM submodule. For the remainder of this section, the examples use ports with a Gigabit Ethernet output and an ASIIn association.
CBR PaddingLogical output ports have the capability of padding the output bitstream in all net-working outputs (UDPOut, RTPOut, ATMOut and Backhaul) to make it a CBR (constant bit rate) stream. When enabled, this feature causes the output port to add NULL packets to the outgoing transport stream to make it CBR.
A CBR stream can support interoperability with legacy devices that are incapable of VBR (variable bit rate) operations. PCRs (Program Clock References) are also re-stamped to match the outgoing rate.
Configuring CBRPadding
To configure the CBR padding function, do the following in the Transport Stream section of a logical Port Configuration page (shown below).
NOTE If a logical output port (for example, UDPOut) is associated with a logical input port (for example, UDPIn), the logical input port cannot be deleted until the associated logical output port(s) is (are) deleted. For example, if you create UDPIn1/0 and then create UDPOut1/0 and UDPOut1/1, both associated with UDPIn1/0 and then attempt to delete UDPIn1/0, this operation will fail (regardless of whether or not there are routes between these ports).
NOTEThis feature requires the presence of at least one PCR flow in the stream routed to the output port.
309
iPlex Web Interface User Guide
Enable CBR Padding: Check this box to enable the function. If the function is enabled, a new field appears where you can configure the desired stream rate.
CBR Padding Bit Rate (bps): Enter the desired overall rate in bits per second.
CBR PaddingStatistics
Once CBR Padding is enabled, the statistics page for the port contains additional information about the status of the PCR padding function activity (see below). This information is useful in solving problems related to CBR padding.
Transport StreamEnable CBR Padding: Indicates with Yes or No whether the CBR Padding function is enabled or disabled.
CBR Padding Bit Rate (bps): If CBR Padding is enabled, this field is present and shows the configured target bit rate.
CBR Padding StatisticsThis section is present if CBR padding is enabled. The fields are event counts, and their meanings are as follows.
NOTE When configuring this feature:• MPORTANT: Make sure that the overall bit rate must be higher than the peak rate
of the stream coming out of the port.This function is not capable of reducing the bit rate of a bitstream to be compatible with a given padding level. If you need such a reduction, you need to have a transrater installed in your system. The CBR pad-ding function can smooth instantaneous peaks, but you run the risk of loosing buffer model compliance (and PCR interval compliance). If the incoming rate is higher than the configured padding rate for an extended period of time, there will be data loss.
• The padding function depends on PCRs to operate. If the bitstream does notcontain PCRs, it cannot be CBR-padded.
At the network level, the resulting packet stream will be CBR within 100 millisecond windows.

iPlex Web Interface User Guide
Invalid PCR Instances: In normal operation, this count is expected to stay at zero. A non-zero count here indicates a potential problem with the stream source. On satellite feeds, this may indicate noise or corruption in the feed. It is uncom-mon to see a count of invalid PCRs.
PCR Discontinuity Instances: In normal operation, this count is expected to stay at zero. A non-zero count may be a symptom of a misconfigured upstream source, or a satellite feed that is going in and out of lock.
PCR Timeout Instances: This count indicates the number of times a PCR disap-peared from the stream. This may be a normal event: for example, if an encoder is reconfigured, it will stop streaming for a short period of time and cause this count to increment. Another situation is when a service is active only during certain times of the day: this count will increment every time the service disappears. If this count is non-zero and that is unexpected, the upstream sources must be checked.
Input Rate Too High Instances: This count must always be zero. If it is non-zero, it indicates that the stream in the port exceeded the configured CBR padding rate. This must be addressed by either reducing the bit rate of the sources, or by increasing the value in the CBR Padding Bit Rate field.
Buffer Allocation Failures: This count must be always zero. If it is ever non-zero, please contact TANDBERG Television Customer Support.
Null Packets Inserted: This count must always increment. It records the number of null packets added to the output to reach the desired rate.
PCR Packets Inserted: This count may or may not increment. The output port may insert “extra” PCR packets to maintain DVB PCR interval compliance after re-stamping. It is not an error to have a non-zero count here. See NOTE that fol-lows.
CBR PaddingOperation
The CBR padding is performed as follows:
1 NULL packets are added at the right places in the bitstream to make it CBR.
2 PCRs are corrected to reflect the fact that the bitstream is CBR.
This function can also insert extra PCR packets to maintain the DVB compliance, that is, to insure the 40 millisecond maximum PCR interval.
NOTEThere will be a problem in the output every time this counterincreases.
NOTE If you have PCRs in a separate PID and this count is incrementing, you will see a higher bit rate in the PCR PID than the input rate. Again, this is normal and no action is required.

DVB-S2 SupportDVB-S2 (Digital Video Broadcasting - Satellite - 2nd Generation) allows trans-mission of one or more MPEG-2 audio/video streams modulation with constant or adaptive encoding. DVB-S2 is an enhanced specification replacing the DVB-S standard which is used for satellite broadcasting used by mobile units for sending external footage back to television stations.
ASIPlus CardThe iPlex supports DVB-S2 by the ASIPlus card via CCM (Constant Coding and Modulation) and ACM (Adaptive Coding and Modulation) modes, which opti-mize the transmission parameters for various users.
For CCM functionality, the ASIPlus card needs to have non-zero bitrate present in the license field. This can be confirmed by viewing the ASIPlus control port statistics. The maximum allowed bitrate per ASIPlus card is 135 MBits/sec. This enables the user to select CCM mode from the ASIPlus control port configura-tion page.
Once the CCM mode is selected, the iPlex creates 2 ASIOut ports for that ASIPlus card and the licensed bitrate is applicable per each ASIOut port. For example, if the ASIPlus card is licensed for 100 MBit/sec, then each ASIOut port will have the capability to handle up to 100MBit/sec.
For ACM functionality, the ACM license flag needs to be selected. If selected, then the allowed bitrate for CCM becomes the maximum allowed symbol rate per ASIOut port. So, in the above example if ACM is licensed for the ASIPlus card, then the maximum allowed symbol rate per ASIOut port will be 100 MSymbol/sec.
Once ACM or CCM mode is selected, 2 ASIOut ports are created, and their corre-sponding SME network interface ports are also created. For example, if an ASIPlus card is present in slot 2, then an ASIPlus1/2 control port is created at boot time, and once ACM or CCM mode is selected, iPlex will create ASOut1/4 and ASIOut1/5 ports as well as network interface ports SME1/4 and SME1/5.
Selecting ACM or CCM ModeThe following screenshot shows the ASIPlus port configuration where you can select an ACM or CCM mode to support DVB-S2.
NOTEMedia routing feature is not available for these created ports.

The mode includes these choices: DVB-CA IP, ASIOutACM, ASIOutCCM, and Inline DVB CA.

Input Ports and PacketizersThe iPlex will accept data that is to be injected using the following protocols:
• IP Forwarding: these are raw IP packets received by the iPlex to be forwarded over the DVB-Sor DVB-S2 link.
• UDP/IP: the data to be injected is delivered to the iPlex as the payload of UDP datagrams.
• TCP/IP: the data to be injected is delivered to the iPlex using the TCP/IP protocol.
For ACM or CCM functionality, these three ports will be created as attached ports to one of the network interface SME ports.
You can create one of the input ports, IPFwdIn, UDPIn, or TCPIn, select from the Create Network Port page.
Creating InputPorts
IPFwd, UDP, and TCP are created differently. For IPFwdIn, you need to select the Input Blade and the Interface, one of the SME’s.
To create a UDPIn or TCPIn, click the Network Interface radio button, and an Interface parameter appears. Select an SME, then select a Data Type.

SupportedPacketizers
The following packetizers are supported:
• Data Pipe: Takes bits and places them in the payload of transport packets, as per ETSI EN301 192 section 4. This packetizer allows global control of the PUSI bit – that is, the PUSI bitwill be either set on all transport packets or not depending on the configuration control.
• Section: Takes sections and maps them into transport packets.
• M2T (Transport): Takes transport packets and injects them as they are.
• IP Tunneling MPE (MPE): Takes IP packets as the input and packetizes them according toETSI EN 301 192 section 7. This packetizer supports the “IP Copy” option for thedestination MAC address, whereby the 6-byte MAC address is formed by pre-pending the 4-byte IP address with two bytes, whose values are configurable per port.
The following table shows the supported packetizers for each type of port.

Mode: Select from a drop-down list a bit rate mode for the video encoder: Stan-dard (max 3.0 s), Low Delay (max 1.5 s) delay, Mega Low Delay (max 0.75 s), or Seamless Variable Delay.
Mega Low Delay mode
This delay mode uses an even shorter delay and smaller decoder buffer size thaneither the Standard or Low Delay modes, which helps shorten channel changetime, but at the expense of reducing video quality. In this mode, the only GOPstructure supported is IP (no B frames), and there are no hierarchical B frames.
Seamless Variable Delay mode
Unlike the other fixed delay modes (such as Standard, Low Delay, Mega LowDelay), seamless variable delay (SVD) mode provides flexibility in choosing delaysand decoder buffer size. The decoder buffer size is calculated as minimum bitrate xdelay (each of which are user parameters), up to 15 Mb for HD or 10 Mb for SD.
Also, in SVD mode, the video bitrate can be changed on the fly without requiringan encoder restart.
Finally, SVD mode is necessary to enable VBR (Variable Bit Rate) operation.
(Standalone) VBR Operation

Invoke the MPEG-4 AVC Ultracompression Transcoder Output Port Configura-tion screen by clicking on Ports under Configuration on the left side Main menu; Summary Port List window opens. Click AVCXcdrOut; list of AVCXcdrOut Port Names appears; click on the Port Name, which you want to configure.
PMT Manipulationand PID Assignment
The AVCXcdrOut port accepts single program transport stream as input. The streams in the program are identified from the entries in the Program Map Table (PMT), which is the transcoder audio source selected in the MPEG-4 AVC Ultra-compression Transcoder Input Audio Channel 1 (or 2-6) Configuration screen, see page 369. Video stream is always transcoded. Audio streams in the input program can be selected for pass-through or transcoding from the above screen. For transcoding, either two stereo pairs or one 5.1 Audio channel is sup-ported.
In the default configuration, all streams in the program, except the video stream, are passed through. If more than one video stream is found in the program, the first video entry in the PMT or the video stream carrying PCR (Program Clock Reference) is selected for transcoding. Other video streams are dropped.
Tables are always passed through. Since video is always transcoded to H264, the stream type of video element is set to H264 in the tables before it is output. If any
380
iPlex Web Interface User Guide
of the audio streams are transcoded, the stream types of corresponding entries in the tables are updated to reflect the new codec type.
The output of MPEG-4 AVC Ultracompression Transcoder contains two pro-grams:
• The first program contains the main video and all the transcoded audio streams and passedthrough streams. The program number for the first program is the same as the programnumber of the input source.
• The second program contains the PIP video. The PIP program number is one plus the mainprogram number. The PMT PID for PIP is dynamically generated to be a unique one.
The PIP video PID is by default 0x201. If this PID already exists in the input pro-gram, a unique PID is generated for the PIP video stream.
Unique PID values are also dynamically generated for any audio channels that are replicated and transcoded. The parameter sets differ depending on the selected Output Stream Type, MPEG or DVB.

Scan Conversion: Select from the drop-down list: Center CutOut, Letter/Pillar Box, or the default, Use AFD (Active Format Descriptor).
381
iPlex Web Interface User Guide
Output AFD: By default, the box is checked, that is, AFD is output (Yes). Uncheck the box if output AFD is not desired (No).
Scan Conversion The above two GUI parameters control the scan conversion process. Whenever a stream with 4:3 aspect ratio (SD) is transcoded to 16:9 output aspect ratio (HD), or vice versa, whenever 16:9 is transcoded to 4:3, the transcoder needs to make a decision on how to format the input picture onto a different-sized output. The right decision will depend on what the “active area” is within the input coded frame. For example, if we are transcoding from 16:9 to 4:3:
• If the active area occupies the full 16:9 coded frame, the 16:9 frame will be letter-boxed ontothe 4:3 output (that is, black bands are added to the top and bottom).
Input Output
• If the active area is 4:3 content centered within the 16:9 frame (that is, with black bands on thesides), the sides will be cropped and the 4:3 center-cut picture will be fit onto the 4:3 output.
Input Output
AFD is a 4-bit value carried in the user data of an MPEG-2 stream (or the SEI data of a H.264 stream) that signals the active area within the coded frame. The transcoder will look at the input AFD information (if present) and the input aspect ratio to determine how to resize the picture for the new output aspect ratio, as well as to output new AFD information.
If AFD information is absent or disappears on input, the transcoder will assume that the active area is the same as the aspect ratio of the coded frame, per specifica-tion: it will assume a default AFD value of 1000b as the coded frame.
The Scan Conversion parameter controls the picture resizing. If set to Output AFD (default), it will perform the scan conversion based on input AFD, as described above. The other two options override this behavior. If set to Letter-box/Pillarbox, it will ignore input AFD and will always perform letterboxing (16:9 -> 4:3) or pillarboxing (4:3 -> 16:9). If set to Center Cutout, it will ignore input AFD and will always perform center cutout (cropping) of the input picture.
The Output AFD parameter controls whether or not the transcoder will output AFD to describe the output active area, regardless of any scan conversion being
NOTEThe Scan Conversion parameter only applies when transcodingfrom 16:9 -> 4:3 or 4:3 -> 16:9.

performed. This parameter applies in all cases (16:9 -> 4:3, 4:3 -> 16:9, 4:3 -> 4:3, and 16:9 -> 16:9).
If transcoding from 4:3 -> 4:3 or 16:9 -> 16:9, no scan conversion is performed, as the output picture is the same size as the input picture. However, it will output valid AFD information, subject to override by the Output AFD parameter. If input AFD is present, it will be copied to the output AFD. If input AFD is absent or disappears, it will output 1000b - “as the coded frame”.

MPEG-4 AVC Ultracompression (Single Slot) Transcoder Input Port Configuration and StatisticsTo set up the MPEG 4 AVC Ultracompression (Single Slot) Transcoder Input, you must configure the variables present on its General configuration page. Depending on your needs, you may need to configure variables found in the Advanced page.
By default, the transcoder will simply pass-through the audio streams present in the input program unmodified. If you wish to transcode the audio as well, the set-tings for that are found in the Audio Channel 1 through Audio Channel 8 screens. Please note that it is not possible to simultaneously pass-through and transcode the same audio channel, but it is possible to replicate a transcoded audio channel. Finally, if your transcoder is licensed for PIP, you can configure that in the PIP Configuration screen.
Each MPEG-4 AVC Ultracompression (Single Slot) Transcoder port is located on an MPEG-4 AVC Ultracompression (Single Slot) Transcoder submodule installed in a slot on an MCM blade. There are slots for eight such submodules per unit. The advantages for the single-slot transcoder are:
• Fits in a single slot, so 8 of them can be fitted in one iPlex
• Improved video quality compared to the dual-slot encoder
• Up to 8 audio channels can be transcoded by each card
The AVCXcdrIn is a logical name of the MPEG-4 AVC Ultracompression Input Transcoder port. In the following sections, this single-slot transcoder is referred to briefly as AVCXcdrIn Single.

Configuration > MCM > ASIIn > ASIIn1/6In the ASIIn Configuration page:
1 Type a description of the interface and select the active channel (the ASIInsubmodule has two physical inputs, A and B—input A is located at the top ofthat submodule).
2 Enable Table Forwarding.
3 The stream type must match the incoming stream (GI, MPEG, DVB orATSC). For this example, we will assume a DVB feed. For DVB feeds, youhave the option of parsing the SDT, NIT, and CAT—more information aboutthe stream displays (for example, program names from the SDT).
4 After completing the configuration, click Apply.
STEP 3:Checking ASIIn
Statistics
Statistics > MCM > ASIIn > ASIIN1/6If the Programs List is empty, there is no feed. Check by clicking Stream. If there are no statistics then there is no signal. Check the port: Statistics > Ports >ASIIn. The port should say “In Sync.” If the port says “No Signal,” there is a problem with the connection or the feed upstream.
STEP 4: Creatingthe UDPOut Port
Configuration > New PortThe first item on the Configuration menu tree allows you to create a new logical network port.
ASI (Asynchronous SerialInterface) One of DVB’s physical
interfaces used for transmittingMPEG-2 Transport Streams.

Scenario 2: Routing a Custom Program from ASIIn to UDPOutThe second configuration might have a non-compliant stream from the encoder that lacks tables, or you may just want to change SDT information, the program number or the PID value.
The iPlex can compensate for the non-compliant stream as long as the operator knows which kind of stream is in each PID. Given this information, the iPlex can generate the tables and add them to the stream. Additionally, the iPlex can modify existing values within the stream, such as a program number.
In this example, we will assume an encoder connected to ASIIn1/6 with MPEG-2 video on PID 0x20, MPEG-2 audio on PID 0x21, and PCRs in the video PID.
Physical SetupMCM: ASIIn cable to ASIIn port from an external Encoder or a demodulator.
SCM: Fiber cable connected to Gigabit Ethernet [GE1] to the network switch, router or another iPlex.
Steps1 Create a UDPOut port, see page 419.
2 Configure Media Routing—to create tables and route the stream, see page 109and page 112.■ Program Creation.■ Add Elements.■ Route the Stream.

Configuration Questions and AnswersThe following section covers some of the configuration issues you may encounter while setting up the iPlex.
Topic 1: UDPOut Settings
Question Why are some UDPOut ports restricted to transmitting content from only one input port?
Answer There are three kinds of UDPOut ports:
1 Ports that transmit over the Gigabit Ethernet (GE) interface(s)
2 Ports that transmit over the ATM interface(s)
3 Ports that transmit over the SME interface(s)
Gigabit Ethernet Ports can only transmit programs from a single input, defined at the time of the port’s creation. This is done to optimize chassis resources. Ports that transmit over ATM or SME have no such limitations. If you need to create a network port over Gigabit Ethernet to transmit a multi-program transport stream with elements from multiple inputs, you can use a backhaul port, which does not have the same limitation as the UDPOut port
Question What is the meaning of the IP address entered in the UDPOut port.
Answer The IP address you enter in the UDPOut port is the IP destination address of the stream—that is the address you send the streams to. This can be a unicast address or a multicast address.
Question What is the relationship between output ports and input ports/blades?
Answer Input and output streams have associated “ports.” The ports may be either physi-cal ports; that is, ASI Input or Output ports, or logical ports that you create, such as UDP or RTP ports. Ports exist in the chassis blades. For physical ports, the blade is where the port is physically present; for logical ports, you must choose the blade based on the following criteria:
■ If you want to create an UDPOut port that streams over ATM, then you have tocreate it on the blade that has the relevant ATM submodule. The same appliesfor an UDPIn port that receives from ATM.
■ If you want to create an UDPOut port that streams out on Gigabit Ethernet,then you must create it in the blade that has the content that you want to route.
■ If you want to create an UDPIn port that receives from Gigabit Ethernet, youcan create it in any arbitrary blade, although TANDBERG Televisionrecommends that you create it on the blade where you will route most of theoutputs.

Question Can the UDPIn port accept streams from multiple resources?
Answer No. Each UDPIn port can only accept a single stream (single or multiple pro-grams). If you want to support multiple programs, just create multiple UDPIn ports.
Question How is channel selection made on input streams from server?
Answer What characterizes each UDPIn is a UDP port number and possibly by a multicast IP address, if you are using multicast. You need to configure the UDPIn ports to match what the server is doing. For example, if your server has two streams out, one on 225.1.1.1, port 2001, and another on 225.1.1.2, port 2002, you create the two UDPIn ports with these parameters, and you have a one-to-one “connection” between the ports and the content.
Topic 2: iPlex IP Settings
Question Can iPlex work as a switch between VLAN ports?
Answer Yes. The iPlex has full VLAN capability on the GE ports. The way it works is as follows: you can group an arbitrary subset of the GE ports into a VLAN. Then you assign an IP address to this VLAN. Logically, it works like this:
You must go to the Configuration/IP Routing/VLAN menu, create a new VLAN, select which physical GE ports will be in this VLAN, and assign it an IP address/port. The iPlex will respond to that address on any of the selected ports, and will provide a traditional transparent bridge for unicast traffic. iPlex will not forward
427
iPlex Web Interface User Guide
multicast traffic between VLAN ports. The only exception is Spanning Tree BPDUs, which are automatically forwarded.
Question Do the control ports and GE ports need to be on different networks?
Answer Yes, they do. This means that you cannot have a streaming client in the same machine that you are using for control, unless that machine has multiple Ethernets to the different LANs.
NOTEIn the UDPOut configuration window, you can select into whichVLAN that particular traffic will egress. If the VLAN has multiplemembers and the UDPOut has a multicast destination IP address,by default, the packets will egress on all ports, but you can changethat in the Configuration/IP Routing/Multicast window.

Network Redundancy Diagram
The TANDBERG Television (1+1) Redun-dancy SolutionThe TANDBERG Television iPlex product line offers (1:1) redundancy without the need for an external management system. This ensures maximum reliability with a fast switchover time in case of failure and avoids the need to use expensive video or ASI switchers. This model also allows for in-service software upgrades (that is, the ability to perform software upgrades with no down time).
A diagram of the iPlex Redundancy System is shown below.

Input Redundancy OptionsTo ensure fast switchover, both the primary and hot-standby components process the data in parallel. This requires that both the hot standby and the primary com-ponents have simultaneous access to the video and ASI input signals. The means by which this simultaneous access is done is left to the discretion of the customers (i.e., it is a trade-off between reliability and cost).
The following alternatives are available:
• Many receivers (video or ASI) have multiple outputs. These multiple outputs can be cableddirectly to primary/hot-standby pairs. A configuration such as this has a single point of failure(the receiver).
• If the receiver does not have multiple outputs, an appropriate Distribution Amplifier (D/A)can be used. Distribution Amplifiers are typically very reliable.
431
iPlex Web Interface User Guide
• Customers desiring maximum redundancy will use separate receivers for the primary/hot-standby pair.
Output Redundancy Options for IPTVEach iPlex has two Gigabit Ethernet ports for output. These ports use the indus-try-standard “Small Form-factor Pluggable” (SFP) transceivers, available as 1000BaseT copper, multimode fiber, or single-mode fiber. The configuration of these ports is up to the customer; the streams can be replicated on them, or split between them in any way.
In a redundant system, both ports are connected to the network, but only the pri-mary unit will be actually transmitting. The hot-standby unit will be “forming” the packets internally, but will not transmit to avoid duplication. If a redundancy switch happens (either automatically or manually), the unit transitioning from hot-standby to primary will start transmitting, and the unit transitioning from primary to hot-standby will stop transmitting. As with the control port, the primary/hot-standby gigabit data ports share one single IP address.
NOTE The iPlex has the capability of switching the redundancy on loss of input signal if so configured.
432
iPlex Web Interface User Guide
Customers have a few alternatives on how to connect the primary/hot-standby units to the distribution network. As with the input ports, these alternatives repre-sent a trade-off between cost and reliability, as follows:
• For customers seeking the lowest-cost solution, both outputs can be connected to the sameswitch or router. This choice again leads to a single point of failure (that particular switch orrouter). The backup iPlex turns off the gigabit link to make the operation simpler for therouter or switch.
• For customers seeking the maximum reliability option, each iPlex output can be connected toan independent switch.

iPlex Unit PairingThe iPlex does not need any special hardware to support redundancy. For iPlex, the redundancy is all software with the use of Ethernet and GE ports available on SCMs and MCMs subsystems. The front panel LCD is also used for displaying state of units in a redundant system.
The iPlex units are grouped into primary/hot-standby pairs. The two units in the pair are required to have the same configuration (that is, the same submodules in the same locations and the same licenses).
Redundancy Port on iPlexEach iPlex has a dedicated Ethernet 10/100 copper port for redundancy control. Pairs of redundant units are connected through this interface. Customers have a choice of just using a crossover or normal cable for this connection (to reduce the number of components; the system auto-detects MDI-MDIX), or using a switch interconnecting multiple units (to allow for flexibility when selecting the pairs). This “redundancy control network” is used by the paired units to exchange config-uration and state information, and to keep their settings synchronized.
Control Port on iPlexThe iPlex has another 10/100 copper Ethernet port for control. Web GUI, CLI and/or SNMP transactions happen through this port. Each iPlex has its own indi-vidual IP address for the control port. A redundant pair also has a common IP address, which is always used by whatever unit is currently the primary. This way, the management system (or the operator) does not need to know which individual unit is the primary (online) to be able to configure it. Configuration actions done to the primary unit are automatically reflected to the backup.
This port is also the first backup for the redundancy port. When communication over the redundancy port fails, all the traffic to the other unit happens on this port until the redundancy port up back to life.

Operational Aspects of Redundancy
Configuration Changes and RedundancyConfiguration changes made to a primary unit automatically change configuration of the associated hot-standby unit, as well.
Operating Method Using External Redun-dancy SwitchesThis section explains how you can use external redundancy switches in conjunc-tion with the iPlex platform. The external redundancy switches switch between redundant ASI Outputs. You can use any hardware switch that provides at least one of the modes of operations described in the following sections.
Automatic Mode When you configure an external switch in automatic mode, it does not need oper-ator intervention for switching to the redundant output in the event of failure of the output from the primary blade. The switch is capable of detecting the alarm on the primary chain and able to switch to the output of the hot-standby unit auto-matically. The iPlex supports this mode and handles the transition seamlessly with-out user intervention in the event of failures.
When you decide to use this operation mode, you must set the iPlex redundancy Mode to “Automatic.”
Manual Mode When you configure an external switch in manual mode, it does require manual intervention for switching to the redundant output in the event of failure of the output from the primary unit. In this mode, the external redundancy switches are capable of detecting and sounding the alarm on the primary chain but they will not switch to the backup output until you manually activate the switch. The iPlex sup-ports this mode in the same way as automatic, and handles the transition to the backup blade internally. However, remember that you still need to switch to output of the standby unit on the external switch.
When you decide to use the manual operation mode, you must set the iPlex Redundancy Mode to “Manual.”
NOTEIt is very important that you save all configuration changes to the startup config file, as changes are not automatically saved. See Copy Startup on page 122 and Copy Running on page 123 on how to save the running-config to the startup.
442
iPlex Web Interface User Guide
AlarmsThe iPlex supports three configurable alarms: Loss of Encoder Sync, Loss of ASI Input, and Loss of ATM Link.
When you enable Loss of Encoder Sync alarm, a primary unit reboots if its encoder submodule detects loss of input. Rebooting the primary unit results in a redundancy flip; the primary unit’s associated hot-standby unit becomes the pri-mary. In a similar fashion, when you enable the Loss of ASI Input alarm, a primary unit reboots if its ASI input submodule detects a loss of input. When you enable the Loss of ATM Link alarm, a primary unit reboots if its ATMInput submodule detects loss of link.
Sync FilesSelecting the Sync Files button results in the synchronization of file systems between the primary SCM and the backup SCM. Then the files contained in the flash directory, the pcmcia/data directory, and the config directory transfer from the primary SCM to the hot-standby SCM. The exception to this is the star-
443

tup-config file in the config directory. The startup-config file transfers automati-cally to the backup SCM at initialization.
NOTEThe Sync Files button is only available if you have redundant iPlexes.

Packet FormatsThis appendix describes the method that the TANDBERG Television data input devices use to partition framed or unframed data into MPEG-2 packets. This description is directed to developers who are responsible for a DVB decoder that must reconstruct an original packet at the receiving end.
The table below provides references to the packet formats available through the iPlex.
MPEG Section Packet FormatMPEG-2 private_sections and all derivatives of the MPEG-2 private_section including MPEG-2 Program Specific Information (PSI) sections and DSMCC_sections ( all sections) may be provided as input to the iPlex by selecting the MPEG-2 Section packetizer. MPEG-2 PSI sections include the PAT (program_association_section), the CAT (CA_sections) and PMT (TS_program_map_section).
The private_section format allows data to be transmitted with the minimum of structure while enabling a decoder to parse the stream. The sections may be used in two ways:
■ Set the ‘section_syntax_ indicator’ to ‘1’, to signal the whole structure (“long”section format). This format is common to all MPEG-2 private_sectionsincluding PSI tables.
■ Set the field to ‘0’ when only the fields ‘table_id’ through ‘section _length’ arepresent (“short” section format).

■ A 32-bit CRC-32 Checksum field. The checksum value is calculated over theentire datagram section. If the section syntax indicator is one then this is aCRC_32. If the indicator is zero, then the field is a checksum. A checksumvalue of zero indicates the checksum was not calculated. A true zero checksumis set to 0xFFFFFFFF.
The MAC AddressField
The MAC address field contains the destination MAC address. The MAC address is stored in the format required by the MPE specification. The MAC_address_6 field contains the lowest byte of the MAC address, and the MAC_address_1 field contains the most significant byte of the MAC address. If the least significant bit of MAC_address_1 is “1”, it indicates a multicast MAC address. (Everything is dis-cussed in terms of bytes in memory not on the wire. Internet standard bit order. Thus, 01:XX:XX:XX:XX:XX is a multicast address.)
TANDBERG Television allows the user to enter the MAC address from the user interface in case no other method exists to obtain the destination MAC address. Note the following information concerning the MAC address field:
You must input the destination MAC address for a directed IP address. Any MAC address, including the MAC broadcast address (FF:FF:FF:FF:FF:FF), a multicast MAC address, or a directed MAC address may be input. (TANDBERG Television does not recommend the MAC broadcast address.)
For a class D, multicast IP address (224.0.0.0 to 239.255.255.255), either input the value or use the multicast address conversion proposed in RFC 1112. The IP address to MAC address mapping occurs as follows:48-bit MAC Address 00000001 00000000 01011110 0XXXXXXXX XXXXXXXX XXXXXXXXClass D IP Address 1110YYYY YXXXXXXXX XXXXXXXX XXXXXXXX
The RFC maps the lower 23 bits of the class D, IP address (X) to the Ethernet MAC address. With the next five bits of the IP address (Y) unused in forming the MAC address, multiple IP addresses can map to the same MAC address. The upper 25 bits of the MAC address are set to 01:00:5E:XX:XX:XX an address owned by the Internet Assigned Numbers Authority for multicast host group mapping.
Broadcast IP address can map in the same manner as directed IP addresses. Do not forward limited broadcast IP addresses (255.255.255.255).
450
iPlex Web Interface User Guide
IP Datagram Data Each IP datagram stores in one MPE datagram section. Thus, each MPEG trans-port packet containing the Payload Unit Start Indicator (PUSI) bit set indicates the beginning of a new section and a new IP datagram. (See the diagram.) Datagrams are limited to one per section, resulting in a limit of one datagram construction per datagram_section.
LLC_SNAPHeader
The eight byte IP LLC_SNAP header appears as: 0xAA 0xAA 0x03 0x00 0x00 0x00 0x08 0x00.

Data Source data (payload only). The maximum number of bytes is 184 per packet.
If the data piping timeout is not enabled, the packetizer will wait until it collects 184 bytes from the data source before issuing a transport packet.
If the timeout is enabled, the packetizer may issue a partially-filled transport packet, if the source does not provide 184 bytes within the timeout period. In this case, the remaining bytes will be presented as an adaptation field filled with 0xFF as padding.

Video Traffic Shaping
Appendix B
453
iPlex Web Interface User Guide
Video Traffic ShapingThis appendix discusses the basic application, issues, and underlying techniques used by video traffic shapers. The examples given here mainly apply to com-pressed audio-visual programs carried via the MPEG-2 transport protocol.
What is Traffic Shaping?
Traffic shaping is the general term given to a broad range of techniques that enforce prioritization policies on the transmission of data over a network link. Conceptually, data traffic shaping is the real-time modification or shaping of the dynamic bit rate profile of data traffic. The implementation of traffic shaping involves determining the sequence of departure times of incoming packets to match the specified egress rate profile. In almost all cases of interest, the desired profile is a lower average bit rate than the input; this gives rise to methods for alter-ing the rate profile using packet buffering. By buffering incoming packets and streaming them out after applying an appropri-ate scheduling algorithm, it is possible to match a variety of rate shapes that are independent of the input arrival pattern. In particular, when the long-term average bit rate of the input and desired profiles are sufficiently close, the combination of buffering and scheduling allows successful traffic shaping with reliable data trans-fer. However, if the discrepancy between the input and desired profiles is too high, practical networking devices with finite buffers resort to packet dropping. The delay of offending packets in the shaping buffers causes an increased average delay with higher variance. The state of variances in the delay experienced by different packets is called “jitter.” This is the result of forwarding compliant packets with lower delay than offending packets.
Why Use Video Traffic Shaping?Video traffic shaping is necessary because of the high cost involved in transmitting the high bit rates typically required for transmitting video programs. To under-stand the economics of compression better, refer to the key concept of the digital video that requires a large quantity of bits every second to adequately represent the video content. TV viewers prefer—and would pay more—to have more channel selections, but physical broadcast television transmission channels have limited capacity. Thus providers of broadcast television services have a direct economic incentive to provide the maximum number of TV channels on their existing trans-mission facilities. This directly translates into a never-ending demand for greater video compression. Of course, TV viewers want TV programs to look good as well! Therefore, there is a clear trade-off between the number of video programs available on a transmission channel and the perceptual quality of those programs. This trade-off is the classic problem addressed by video traffic shaping.
In general, video traffic shaping is necessary whenever real-time video traffic—uncompressed or pre-compressed—must be transmitted over physical channels. The four following scenarios require video shaping:
Traffic Policers enforce trafficpolicies using an instantaneous
approach, by immediately discardingdata packets which violate the policy,
while forwarding compliant packets.
Traffic Shapers enforce trafficpolicies using a longer term
approach, by smoothing incomingpackets using packet buffers, anddiscarding packets only when the
input violates the policy overprolonged intervals.
Thus traffic shapers result in lowerdata loss, while traffic policers exhibitlower average delay and jitter due to
absence of buffering.

• Maximizing the number of video traffic flows—and hence revenues—sent over a givenchannel at a given quality.
• Forwarding video traffic from a higher capacity network into a lower capacity network whileminimizing the impact on quality. The economic case here is the revenue obtainable fromvideo delivery services to destinations that are not serviced by expensive high-capacitynetworks.
• Shaping the rate profile from a variable rate profile into a smooth constant bit rate; preferablywith no quality degradation. This makes video delivery possible over networks that are simplerand cheaper to engineer than those supporting variable rate traffic.
• Lowering the bandwidth allocated to video on existing transmission channels, if the freedbandwidth can be used for more lucrative forms of content, such as enterprise data delivery.
Classes of RequirementsThe iPlex implements single stream video traffic shaping.
Single StreamMPEG-2 Traffic
Shaping
Given:• An uncompressed or MPEG-2 SPTS compressed input stream, and
• A traffic descriptor specificationShape the stream such that:• The output bitstream complies with the MPEG-2 SPTS syntax and buffer models.
• The traffic profile of the stream satisfies the given traffic specification.
• The perceptual distortion between the decompressed output and corresponding input isminimized.
Video TrafficDescriptors
Typical examples of traffic descriptors include CBR and VBR descriptors.
CBR Output Traffic DescriptorAttributes:
• Constant output bit rate
• Maximum output buffering delay
SPTS (Single Program TransportStreams) contain transport
packets corresponding to each ofthe elementary streams
comprising the program, as wellas packets carrying the required
PSI table sections, all multiplexedtogether according to the rules
specified in the MPEG-2 Systemsspecification.
CBR (Constant Bit Rate) Astream with constant short term
bit rate. The bit rate of thesestreams may only vary within a
very narrow range.
455
iPlex Web Interface User Guide
VBR Output Traffic Descriptor
The VBR output traffic descriptor has the following attributes:
• Long-term average bit rate
• Short-term average peak rate
• Maximum output buffering delay
Alternate VBR descriptors exist with the following attributes:
• Minimum short-term bit rate
• Maximum short-term bit rate
• Maximum output buffering delay
VBR (Variable Bit Rate) A streamwith varying short-term and longterm bit rates. The bit rate of thestream can vary randomly within
a well-defined range.

Finding MAC Addresses
Appendix C
457
iPlex Web Interface User Guide
Finding the MAC Address of a Network DeviceThe procedure to find the MAC address of a network device (that is installed in the network and active) is to ping it and look it up in the dynamic ARP table of the device from which you performed the test. The format of these commands are:
Windows:ping IP_Addressarp -a
Unix:ping -c 1 IP_Addressarp -a -n
In both cases, the arp command will dump a list of all known entries in the host being used for the test. You then must identify the one that corresponds to the desired IP address.
This procedure can also be performed in the SCM shell. An example is provided below where the MAC address corresponding to IP Address 192.168.200.2 is determined. The commands to be typed at the prompt are shown in blue, the iPlex responses are in black, and the resulting MAC address is in red.

Configuring Media RoutingThe Media Routing Configuration page contains several display frames for con-figuration purposes. Routing tools allow you to designate Program Routes, Add Programs, Stream Routes, and Remove Selected items.
Display Frames The top-left frame on the page displays the Output or Input List. There are two options to view the information below, either as Programs or Streams. Clicking the Streams radio button will give you a display of PIDs present in the Transport Stream. The top-right frame, Media Routing, will display the choices available. Beneath the Media Routing frame, you will see Routing Tools and Media Routing Information. When you want to create a program route, you must first select the desired output in the Output/Input List (top-left). The Media Routing frame will display your options (top-right). For example, “You can add a program route, cre-ate a new program or add a stream route.”
Navigating MediaRouting
When inside Media Routing, do not use the browser’s navigation tools. Instead, use the Back button that appears in the top-right frame, when required. To return to the original port values, just click the name of the port in the dark blue rectangle under Output/Input List.

Color plays an important role in understanding text within Media Routing:
Red means “inactive” (you must click Apply to activate).
Blue means “active” (for programs, stream routes, and user created programs).
Green is an active element within a program.
Yellow is a ghost program (created route with no program on the input).
Basics of MediaRouting
A Transport Stream, containing unique packet identifiers (PIDs), received by the iPlex via ASIIn (two per submodule), may contain many elementary streams multi-plexed together. The iPlex software analyzes the content and allows you to reorga-nize the stream elements into new programs, which it can then route to multiple output ports. To understand this complex process, the following definitions of the Transport Stream content will help you configure the iPlex’s routing features.
Transport Stream: One or more programs, each of which contains one or more elementary streams and other streams, such as data, multiplexed together.
Program: A number given to a service that is used to reference one or more ele-ments.
Element: An entity, such as video or audio data, which is put together with other elements to make up a program.
To have a better understanding of these definitions, look at the Statistics page for ASIIn, which displays information that the iPlex gathers from the Transport Stream. Program information is as follows: MPEG program number, DVB name, DVB original network ID, and DVB service type. That is, the program identifier number, the name of the program, the original network number assigned to it, and the service type; for example, Digital Television Service and Data Broadcast Ser-vice. If you click the Element radio button, it will display the PIDs associated with the program and element type. Clicking Stream will display all the PID informa-tion in the Transport Stream along with DVB table information. Stream statistics gives you a detailed view of the Transport Stream.
There is a direct correlation between the Program and Element information that comes from Program Specific Information (PSI) as described in the MPEG speci-fication. Stream statistics gives PID information also contained in the Element sta-tistics and other data existing in the Transport Stream.
The method for routing media is to start by creating a program route using pro-grams already existing in the Transport Stream, or creating new programs for rout-ing. However, first you need to select an output device, and if required, add element streams to the new program. PIDs must be unique and are associated with a specific element. More than one program can share the same element. If there are PID conflicts, you can configure the iPlex to fix them automatically.
Program Routingvs. Stream
Routing
The iPlex provides two types of media routing: program routing and stream rout-ing.
The simpler of the two is stream routing. It is used to route individual PIDs from inputs to outputs, optionally remapping the PID value. This means that the iPlex will take all packets of PID X on the specified input and transmit them on the
461
iPlex Web Interface User Guide
specified output, changing the PID to Y. No changes are made to any output tables.
Program routing is more intelligent, but relies on the input PSI tables. Program routing means that the iPlex takes all the elements from Program X in the speci-fied input and routes them to the specified output as Program Y, resolving any conflicts. In this mode, the iPlex parses the PMT for the input, identifies all of the program elements, routes these program elements, and copies any PAT, PMT, and SDT entries (including any descriptors) from the input to the output. The output tables are modified accordingly.
The iPlex will also automatically resolve any PID conflicts. For example, if the routed program has an element on PID 0x200, but PID 0x200 is already in use in the output, the iPlex will automatically remap the incoming PID 0x200 to a free PID and adjust the tables accordingly. As well, if the input program changes (for example, a new PID with an additional audio channel is added), the iPlex will auto-matically adjust by routing any new elements, resolving any PID conflicts, and adjusting the tables.
When to Use StreamRouting
Use stream routing when you want to be in full control of the output PID alloca-tion.
When to UseProgram Routing
Use program routing to have the iPlex manage output PID allocation.
How to set upMedia Routing
The following operations are described in this section:
• Adding a Program Route
• Adding a Program
• Creating a Program
• Adding an Element
• Creating an Element
• Adding a Video Element
• Adding an Audio Element
• Adding a Data Element
• Adding a Stream Route
The section also lists DVB Standard PID Numbers.
Adding a ProgramRoute
If you want to add a program route on a UDPOut port, for example, select the UDPOut port from the drop-down list. If you are already at the port, return to the starting point by clicking the port name in the dark blue bar. This will display the Program Route button in Routing Tools.
Click the Program Route button. Then in the Input List select an input port; for example, ASIIn. This will display all available programs by number along with ele-ments contained in the program. By clicking a program number, you can view pro-

gram information. However, to route a program, or programs, you must select the applicable check boxes, and click the Route Selected button. If the program does not have a check box, it means that the program has already been routed.
.
A form containing all the programs you selected will display. This form allows you to optionally change the program number and PMT PID. On a given output port, the program numbers must be unique. If you want the iPlex to automatically resolve program number conflicts, select the check box on the Program Auto Fix column.
The iPlex will only change the program in case of conflicts; otherwise, it will default to the original program number. Multiple programs are allowed to use the same PMT PID. However, if the selected PMT PID is already in use in the output, the route will fail. You can select the check box under the PMT Auto Fix to have the iPlex automatically resolve PMT PID conflicts. Finally, note that the iPlex will always automatically fix any program element PID conflicts. Click on the Route button to complete the process.
NOTEIf the Apply button is visible, it means that your previous configura-tion has not been applied.
463
iPlex Web Interface User Guide
The Program Routes Output screen displays. There is one line for each route. If the line is green, the route succeeds. If the line is red, there is a problem with the route—either a program number conflict or a PMT PID conflict.
Click OK to acknowledge. In the next screen, click Apply to establish the routes that are OK (marked in green).
.
For the failed routes, you will have to start the process again and fix the problems. Selecting the Program Auto Fix and PMT Auto Fix check boxes guarantees that the route will succeed.
Adding a Program You can add custom programs to output ports. First, you have to select the output port and click Add Program, fill out the form, and click the Create button. The new port appears in the port list in red. At this point, you can click the Apply but-ton to commit the changes and create the program, or Revert to cancel. Clicking Apply will change the entry to blue. Notice that this entry also has (User) next to the program number, meaning that you created it.

ASIIn
Configuration > MCM > ASIIn > ASIIn1/6In the ASIIn Configuration page type a description of the interface and select the active channel (the ASIIn submodule has two physical inputs, A and B—input A is located at the top of that submodule). The stream type must match the incoming stream (GI, MPEG, DVB or ATSC). For this example, we will assume a DVB feed. For DVB feeds, you have the option of parsing the SDT, NIT, and CAT—more information about the stream displays (for example, program names from the SDT). After completing the configuration, click Apply.
STEP 3:Checking ASIIn

Scenario 2: Routing a Custom Program from ASIIn to UDPOutThe second configuration might have a non-compliant stream from the encoder that lacks tables, or you may just want to change SDT information, the program number or the PID value. The iPlex can compensate for the non-compliant stream as long as the operator knows which kind of stream is in each PID. Given this information, the iPlex can generate the tables and add them to the stream. Addi-tionally, the iPlex can modify existing values within the stream, such as a program number.
In this example, we will assume an encoder connected to ASIIn1/6 with MPEG-2 video on PID 0x20, MPEG-2 audio on PID 0x21, and PCRs in the video PID.

Scenario 6: Audio-only EncodingFrom the Encoder Input Selection dropdown list, if you select Internal Test Pat-tern, the encoder will produce color bars regardless of whether the input is con-nected. This enables you to run the encoder without a video input.
Some set-top boxes require PCRs in audio-only streams. The encoder PCR PID is configurable. You can put the PCR in one of the two available audio streams. The iPlex allows you to configure a second PCR flow in the encoder, so you can put PCRs in the second audio PID as well. To configure the PCRs, click the Advanced button at the top of the Encoder Plus General Configuration screen.
The procedure to configure audio-only encoding is as follows.
1 From the menu, click Configuration > MCMx > ENC > ENCx/x, wherethe ENCx/x is the specific MPEG Encoder Plus that you want to work with.
2 In the Encoder Plus General Configuration screen, for Encoder InputSelect, click the dropdown list and select Internal Test Pattern.
3 If you require PCRs in both audio streams, click Advanced. Near the bottomof the screen you will find the PCR configuration parameters.
a. Configure the Encoder PCR PID to match the first audio channel PID.
b. Click to select Enable Additional PCR.
NOTEEven though the internal test pattern is selected, the encoder will still show loss of video sync because there is no external video sig-nal. We recommend that you set the encoder to full-D1 resolution (720x480 for NTSC; 720x576 for PAL). If you use a lower resolution, the test pattern will be distorted.
507
iPlex Web Interface User Guide
c. Once you enable the additional PCR, you will have a new field to choose itsPID. Set it to the second audio channel PID. Click Apply.
4 Stream-route the two audio PIDs the desired output. See Scenario 4:Transrating Stream Routes from ASIIn to UDPOut on page 494 for theprocedures for stream routes. Use the steps of the procedures relevant to theports you will be using, even if not transrating.
5 Create user-defined custom programs in the desired output describing the audio-only streams. See Scenario 5: Defining a Program without Setting the PID to Transrate on page 502 for procedures on configuring user-defined custom programs.

A■ AES/EBU (Audio Engineering Society/European Broadcasting Union) is the
name of a digital audio transfer standard. The AES and EBU developed thespecifications for the standard. The AES/EBU digital interface is usuallyimplemented using 3-PIN XLR connectors, the same type connector used in aprofessional microphone. One cable carries both left- and right-channel audiodata to the receiving device. AES/EBU is an alternative to the S/PDIFstandard.
■ AF (Assured Forwarding) is a class of service for applications that require abetter reliability than Best Effort service.
■ ATSC addressable sections (Advanced Television Systems Committeeaddressable sections) Represents Multiprotocol Encapsulation standard (seeMPE).
■ ASI (Asynchronous Serial Interface) One of DVB’s physical interfaces used fortransmitting MPEG-2 Transport Streams.
■ ASIPlus (Asynchronous Serial Interface Plus) A DVB CAS physical interfacethat adds two input and one output port to an ASI board.
■ AT command set A series of machine instructions used to activate features onan intelligent modem. Developed by Hayes Microcomputer Products andofficially known as the Hayes Standard AT Command Set, it is used entirely orpartially by most every modem manufacturer. AT is a mnemonic code forATtention, which is the prefix that initiates each command to the modem.
■ ATM (Asynchronous Transfer Mode) A network technology for both local andwide area networks (LANs and WANs) that supports real-time voice and videoas well as data. The topology uses switches that establish a logical circuit fromend to end, which guarantees quality of service (QoS).
■ AVC (Advanced Video Coding) A digital video codec standard notedfor achieving very high data compression.
B■ Bandwidth The transmission capacity of a communications network expressed
in bits per second.
510
iPlex Web Interface User Guide
■ BE (Best Effort) is a class of service with no reserved resources.■ Bit Rate The transmission speed of binary coded data.■ BNC bayonet connector A commonly used plug and socket for audio, video
and networking applications. BNCs connect two-wire coaxial cable (signal andground) using a bayonet mount. After the plug is inserted, the bayonetmechanism causes the pins to be pinched into the locking groove when theplug is turned.
■ Broadcast: To transmit to everybody on a network or network segment.■ Byte stream: A contiguous group of untyped data. The iPlex can packetize byte
streams by grouping them into MPEG-2 Transport Stream packets.
C■ CA (Conditional Access) Conditional access system used in iPlex to handle
multiple connections to ECMGs.■ CAS (Conditional Access System) Conditional access system to control
subscriber access to broadcast services and events.■ CAT (Conditional Access Table) A table providing information on the
Conditional Access System used in the multiplex. This information is privateand dependent on the CAS, but includes the location of the EMM stream,when applicable.
■ Canonical name The actual name of a resource. For example, a canonical nameof a server is its true name rather than an alias.
■ CBR (Constant Bit Rate) A stream with constant short term bit rate. The bitrate of these streams may only vary within a very narrow range.
■ CBR-ES (Constant Bit Rate - Elementary Streams) The video ElementaryStream (ES) will have a Constant Bit Rate (CBR). The Transport Stream, ofwhich the video ES is one component, will be somewhat VBR when audio andother overhead is added.Recommendation: This setting is recommended for lower bandwidth accessnetworks (e.g. DSL). This setting seeks to constrain the Transport Stream bitrate to a tight range, while simultaneously minimizing network overhead.
■ CBR-TS (Constant Bit Rate – Transport Stream) The Transport Stream (TS)will have a Constant Bit Rate (CBR).Recommendation: This setting is recommended for network operators whowant to simultaneously transmit the live stream and record it for later playbackon a video server (as most video servers require CBR Transport streams). Therate control is designed to maintain a constant Transport Stream bit rate acrossthe network including servers. CBR-TS does not use Null-packet padding toachieve the bit rate, because most video servers will discard the Null-packets.
■ Checksum A value used to ensure data is stored or transmitted without error. Itis created by calculating the binary values in a block of data using somealgorithm and storing the results with the data. When the data is retrieved frommemory or received at the other end of a network, a new checksum iscomputed and matched against the existing checksum. A non-match indicatesan error.

H■ Header In communications, the first part of the message, which contains
controlling data, such as originating and destination stations, message type andpriority level.
■ Host In network architecture, a client station (user’s machine) is considered tobe a host, because it is a source of information to the network in contrast to adevice such as a router or switch that directs traffic. However, in remotecontrol software a host is a virtual client.
■ HP code rate (High Priority code rate) A high priority bit stream. Twodifferent code rates applied to two different levels of the modulation have theaim of achieving hierarchy. Transmission then starts with the code rate for theHP level of the modulation and ends with the one for the LP level.
I■ IP (Internet Protocol) The network layer protocol in the TCP/IP
communications protocol suite (the “IP” in TCP/IP). IP contains a networkaddress and allows messages to be routed to a different network or subnet.
■ IP Address (Internet Protocol Address) The layer-3 address of a computerattached to a TCP/IP network.

■ MPEG (Moving Pictures Experts Group) Pronounced “em-peg.” Afamily of standards used for coding and decoding audio-visual information in adigital compressed format. An international standard for generic coding(compression) of digital video and/or audio information. There are threeflavors of this standard—MPEG-1, MPEG-2 and MPEG-4. —MPEG-1 was the first standard (ISO/IEC 11172; 1993), and is targetedtowards video CDs and VHS quality, typically at bit rates of about 1.5 Mb/s. Ithas since been superseded by MPEG-2, which is currently the most prevalentstandard (ISO/IEC 13818; 1996). —MPEG-2 is directed towards entertainment and broadcast quality video fortelevision and DVD applications, typically at bit rates ranging from 2 – 8 Mb/s. An MPEG-2 system provides a method for combining (multiplexing) severaltypes of multimedia information into one stream that can be (either):Transmitted on a single communication channel, or stored in one file of adigital storage medium (DSM). —MPEG-4 is a recent standard (ISO/IEC 14496; 2000) which is moreambitious in scope, targeting a wide variety of applications ranging from low-bit rate wireless and Internet streaming video to very high quality DVD video.However, the standard is in continuous flux, and its compression efficiency forentertainment and broadcast quality video has not yet demonstrated significantimprovement over MPEG-2.

Q■ QAM (Quadrature Amplitude Modulation) A cable networks’ modulation
technique that generates four bits out of one baud. For example, a 600-baudline (600 shifts in the signal per second) can effectively transmit 2,400 bpsusing this method. Both phase and amplitude are shaped with each baud,resulting in four possible patterns.
■ QPSK (Quadrature Phase Shift Keying) A phase modulation scheme used insatellite data transmission. Bits are encoded in sequential carrier phasetransitions.
■ QoS (Quality Of Service) The ability to define a level of performance in a datacommunications system. For example, ATM networks specify modes of servicethat ensure optimum performance for traffic such as real-time voice and video.
R■ RFC (Request For Comments) A document that describes the specifications for

■ SSH (Secure SHell) A protocol that runs over TCP to cryptographically securelogin sessions.
■ SSL (Secure Sockets Layer) The leading security protocol on the Internet.When an SSL session is started, the server sends its public key to the browser,which the browser uses to send a randomly generated secret key back to theserver in order to have a secret key exchange for that session.
■ Submodule A PCI-based mezzanine card. Small and compact (74mm x 149mm)and providing 32 or 64-bit data paths, submodules enable a large variety of PCIproducts to be retrofitted to other bus environments.
■ Subnet Mask The Subnet Mask is used to divide the IP address space intoranges of addresses called “subnets”. IP hosts in a subnet assume that theyhave a direct connection (for example, connected to the same Ethernet hub)and talk directly to each other. The subnet mask divides the IP address intoparts: a network number and a host number. Hosts whose network number isthe same are in the same subnet. The subnet mask is a 32-bit field where “1”bits indicate what part of the IP address is a network number. Subnet masksare typically expressed in the same quad dotted notation as IP addresses.
T■ TCP/IP The Transmission Control Protocol (TCP) on top of the Internet
Protocol (IP). Enables communication between different types of computersand computer networks. The Internet Protocol is a connectionless protocolthat provides packet routing. TCP, which is connection-oriented, providesreliable communication.

■ TDT (Time and Date Table) A DVB SI table that gives information relating tothe present time and date. This information is given a separate table due to thefrequent updating of this information.
■ Teletext A popular European broadcasting service that transmits text to a TVset that has a teletext decoder. It uses the vertical blanking interval of the TVsignal (black line between frames when vertical hold is not adjusted) totransmit about a hundred frames.
■ TFTP (Trivial File Transfer Protocol) A version of the FTP protocol that hasno directory or password capability.
■ TOS (Type Of Service) A field in an IP packet (IP datagram) that is used forquality of service (QoS). The TOS field is 8 bits, broken into five subfields.
■ TOT (Time Offset Table) A DVB SI table that contains time zone and timeoffset information in relation to the TDT.
■ Transport Stream: (TS) One or more programs, each of which contains one ormore elementary streams and other streams (such as data) multiplexedtogether. An MPEG-2 transport stream is a standardized system layer ofMPEG-2 that combines video, audio and data in a packetized stream.
■ Traps SNMP traps are unsolicited events sent by the SNMP Agent to themanager stations in their list of trap destinations.
■ TTL (Time To Live) This value decrements each time the IP frame moves through arouter. When the number reaches the value of zero, the stream is discarded.
U■ UBR (Unspecified Bit Rate) An asynchronous transfer mode (ATM) level of
service that does not guarantee available bandwidth. It is very efficient, but notused for critical data.
■ UDP (User Datagram Protocol) A connectionless transport-level protocol usedin the suite of IP-based protocols.- Enables sending of data from one computer to an application running inanother computer. - Like TCP (Transmission Control Protocol), UDP is used with IP (theInternet Protocol).- Unlike TCP, UDP is connectionless and does not guarantee reliablecommunication; the application must deal with lost or out-of-order packets.
■ UDPIn The UDPIn port receives data for injection into the payload of UDPpackets. UDP is a connectionless, unreliable protocol with no flow control;packet loss between the data source and the iPlex is not corrected.

or server to server.■ Universal Time This time is simply the number of hours, minutes, and seconds
which have elapsed since midnight (when the sun is at a Longitude of 180°) inthe Greenwich time zone. Since the Earth's rotation is irregular on the 0.1-slevel, a local approximation to universal time not corrected for polar motion is
521
iPlex Web Interface User Guide
often used. This is called UT0, and also referred to as Greenwich Mean Time(GMT). In UT0, 24 universal hours are defined to be a mean solar day.
■ User interface The combination of windows, menus, keypad commands andhelp messages that provides a way for a user to interact with a program.
V■ VBI (Vertical Blanking Interval) A part of a television transmission signal that
is blanked or left clear of viewable content to allow time for the TV¦s electrongun to move from the bottom to the top of the screen as it scans images. Theblank area is now being used to broadcast closed caption and HTML-formatted information.
■ VBR (Variable Bit Rate) A stream with varying short-term and long term bitrates. The bit rate of the stream can vary randomly within a well-defined range. Application: The Transport Stream (TS) will have a Variable Bit Rate (VBR).The bit rate of the TS will never exceed the maximum bit rate selected and itwill fall to lower rates whenever possible, consistent with the selected videoand audio quality settings and the complexity of the audio and video streamsbeing encoded. Recommendation: This setting is recommended for higher bandwidth accessnetworks (e.g. FTTH) where busting to high rates is tolerable and desirable formaximum video and audio quality but constant padding to the maximum ratewould be unacceptably wasteful.
■ VCI (Virtual Channel Identifier) A unique numerical tag as defined by a 16 bitfield in the ATM cell header that identifies a virtual channel, over which thecell is to travel.
■ VLAN (Virtual LAN) A logical subgroup within a local area network that iscreated via software rather than manually moving cables in the wiring closet. Itcombines user stations and network devices into a single unit regardless of thephysical LAN segment they are attached to and allows traffic to flow moreefficiently within populations of mutual interest.
■ VLAN Tagged Packets VLAN tags used to define multiple LANs in the samephysical segment. A tagged packet has an extra header added between the layer2 and the layer 3 headers (the tag) that indicates to which VLAN it belongs.Typically only switches and routers handle tags, not end-hosts.
■ VPI (Virtual Path Identifier) An eight bit field in the ATM cell header whichindicates the virtual path over which the cell should be routed.
■ -VPS (Video Programme System) A system implemented primarily in VCRs tosignal program start/stop. This is used mostly in Europe.
