LinuxGNU GENERAL PUBLIC LICENSEVersion 2, June 1991Copyright (C) 1989, 1991 Free Software Foundation, Inc.59 Temple Place, Suite 330, Boston, MA 02111-1307 USAEveryone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge forthis service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbidanyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributes of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow.GNU GENERAL PUBLIC LICENSETERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The “Program”, below, refers to any such program or work, and a “work based on the Program” means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term “modification”.) Each licensee is addressed as “you”. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)

DM Network CherryPicker 4.1 User Guide i

These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as aspecial exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalentaccess to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License.However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein.You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or amongcountries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and “any later version”, you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.

NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITEDTO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY OU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Introduction

DM N

What is a DM Network CherryPicker?

The Terayon DM Network CherryPicker® is an MPEG-2 digital stream management system that extends the next generation of broadband service solutions to your network. Based on field-proven Terayon CherryPicker technology, the DM Network CherryPicker delivers up to four times the stream processing capabilities of earlier CherryPicker models in a more compact, one rack unit chassis.

The DM Network CherryPicker aggregates source feeds from satellite, local content encoders, ad servers and video servers and dynamically routes selected programs over DHEI, DVB-ASI, ATM, Fast Ethernet and Gigabit Ethernet networks. Proprietary ASICs rate shape MPEG-2 transport streams with unparalleled picture quality allowing you to squeeze up to four HD streams into one 256 QAM channel.

The CP Controller, required in previous CherryPicker models, is now integrated into the single chassis design. The slim, one rack unit chassis holds five user-selected input/output modules. This flexible architecture gives you the ability to select modules that optimize your system’s capacity today and make easy upgrades in the future.

Program redundancy, introduced with the DM Network CherryPicker Software v4.0 release, provides the ability to groom a backup service in case of primary service loss. You can also specify that the service automatically be switched back to the primary program when the primary input reappears.

The master control management console, also introduced with the DM Network CherryPicker Software v4.0 release, allows for a collection of DM Network CherryPickers to be connected via Gigabit Ethernet and controlled in a single graphical user interface (GUI). Grooming and alarm monitoring of multiple units can all be accomplished within a single interface. Cross-DM grooming allows you

etwork CherryPicker 4.1 User Guide 1-1

to groom input programs from one DM over a Gigabit Ethernet network to the output of another DM.

The DM Network CherryPicker is fully interoperable with all DVB and MPEG-2 compliant equipment from leading providers to the cable industry, including existing CherryPicker products. It can be seamlessly integrated via its SNMP management capabilities and is fully compliant with ANSI/SCTE 35 2001 and ANSI/SCTE 30 2001 DPI standards for cueing and splicing.

What Does a DM Network CherryPicker Do?

Functioning completely within the digital domain, the DM Network CherryPicker receives digital program multiplexes and outputs digital program multiplexes without any conversion to analog.

The primary features of DM Network CherryPicker are:

• grooming• local program insertion• content aggregation for Gigabit Ethernet distribution• data injection• video on demand (VOD) and near video on demand (NVOD)

Grooming

Grooming is selecting specific programs from an incoming transport feed and bundling them into a new bouquets of programs for distribution. This is referred to as cherrypicking.

With the DM Network CherryPicker Software 4.1, you can select specific programs from input multiplexes and groom them to four customized output multiplexes. In the

1-2 DM Network CherryPicker 4.1 User Guide

example below, programs are being cherrypicked from three incoming multiplexes and being groomed into a single output multiplex.

Figure 1-1 Service Grooming

In this example, the operator has selected two services from the movie provider, three services from the news provider and three services from the music provider.

These eight services are multiplexed using the DM Network CherryPicker to create a bouquet of programs designed to best meet the needs of this operator’s specific market.

Types of Grooming

Four types of grooming are available using the DM Network CherryPicker Software 4.1.

Program Number Service Provider1, 3 HBO

1, 2, 3 CNN

1, 7, 14 MusicChoice

NOTE

DM Network CherryPicker Software 4.1 refers to the identifying number for a stream as the Program number. Throughout this User Guide, the terms Program number, Service number and MPEG number are used interchangeably.

DM Network CherryPicker 4.1 User Guide 1-3

Static Grooming

Static grooming allows you to select specific programs from the incoming transport stream and bundle them into a new bouquet of programs for distribution. This bouquet is distributed until you make a grooming change. You set it and forget it.

Dynamic Grooming

Dynamic grooming allows you to change the programming package your subscribers receive depending on the time of day or day of week. This is time-based grooming.

Custom Grooming

Custom grooming allows you to groom elementary streams out of the incoming transport stream. One popular application of custom grooming is to select a secondary audio stream to be distributed as the primary audio stream. Subscribers are able to watch shows in their primary language without needing SAP-enabled televisions. Custom grooming allows you to customize your service package to the demographics of your area.

Cross-DM Grooming

Cross-DM grooming refers to grooming programs between members of a master control management console group of DMs. Cross-DM grooming allows you to groom input programs from one DM to the output of another DM.

Local Program Insertion

Local program insertion allows you to splice digital program feeds of local content, such as news and weather without converting to analog.

Figure 1-2 Digital Feeds Distributed without Conversion to Analog

Content Aggregation for Gigabit Ethernet Distribution

Adding Gigabit Ethernet functionality to your DM allows you to aggregate and distribute large amounts of content economically to local distribution points closer to the

node. With a centralized acquisition point, you reduce both operating expenses and the complexity of the overall network.

The DM architecture helps you conserve scarce rack space, and save money by consolidating advanced digital video management functions at a central aggregation point and distributing more traditional digital video processing (grooming, rateshaping, ad insertion, data insertion, etc.) to a few DMs placed at smaller hub locations. This distributed architecture allows you to get video services into the network at the earliest possible point without the need to deploy large and expensive solutions at every hub site.

The DM with Gigabit Ethernet is a highly-scalable solution for operators looking to meet existing and future market requirements - more streams processed, served over more outputs, in a smaller box, at a lower cost per stream.

Data Injection

The DM Network CherryPicker can be used to embed data into the output stream. Data injection can be used to send anything from billing codes to PSIP to interactive/enhanced TV content out to set-top boxes in the field.

In order to make interactive features available to the subscriber, transport streams may contain packets of data called triggers. Currently, the trigger resides as a user-definable field contained in the header of the MPEG-2 transport stream. The trigger is inserted by the video content provider and is transmitted to the subscriber’s set-top box. This causes an icon or other flag to appear on the viewer’s screen inviting an interaction.

Should the viewer accept the offer to interact, the resulting request containing the subscriber’s unique identity information is then sent upstream back to the cable provider. When the information is received at the headend the transaction begins.

The DM Network CherryPicker Software 4.1 gives you the ability to insert local triggers into the data stream. It also gives the ability to detect triggers present in incoming feeds and make a decision either to block them or to pass them through.

Video on Demand/Near Video on Demand

DM Network CherryPickers can be used to distribute programming to subscribers immediately upon the viewer’s request. Content can be stored on local servers and distributed to subscribers using far less bandwidth than would otherwise be necessary.

Near Video on Demand (NVOD) also delivers movies and other programs at the request of the subscriber. Unlike interactive VOD, NVOD only allows viewers to choose pre-scheduled start times. Because each NVOD program requires the use of several channels running a copy of the same program simultaneously, the need for more available channels can dramatically increase.


Because the DM Network CherryPicker Software 4.1 gives you the ability to splice signals from different feed sources, you now have the flexibility to integrate operator-provided content, such as VOD and NVOD, into your digital offering.

Where Does the DM Network CherryPicker Fit into a Headend?

The DM Network CherryPicker acts as a hub between the incoming and outgoing services.

Figure 1-3 Video Service Hub

DM Network CherryPickers work with digital content from a wide range of sources. Digital streams come in from network television broadcasters, local broadcasters, video servers, Internet data providers, video on demand servers and ad servers.

The DM Network CherryPicker accepts digital feeds in several formats:

• standard definition digital programming• local digital programming • HD programming• data• Internet• ad server content• VOD & NVOD content• PSIP generators

Motorola Headend

Without a DM Network CherryPicker installed, a standard Motorola/General Instruments headend configuration is laid out as shown in the diagram below:

Figure 1-4 Motorola Headend without DM Network CherryPicker

The Integrated Receiver Transcoder (IRT) receives the L-band signal, demodulates, decrypts, re-encrypts and modulates up to 12 video programs. The C6U upconverts the IF signal into RF using a 6MHz channel. The RF signal is sent to the subscribers’ set-top boxes. Only one input feed goes into the output.

Figure 1-5 Motorola Headend with DM Network CherryPicker

With a DM Network CherryPicker installed, multiple IRTs receive the L-band signal, demodulate and decrypt. The DM Network CherryPicker then grooms multiple programs and may remultiplex programs before sending the new output program to a downstream IRT for encryption and modulation. The C6U, as before, upconverts the IF signal into RF using a single 6MHz channel. The RF signal is sent to the subscribers’ set-top boxes. Multiple input feeds go into the output.


Scientific-Atlanta Headend

Without a DM Network CherryPicker installed, a standard Scientific-Atlanta headend configuration is laid out as shown in the diagram below:

Figure 1-6 Scientific-Atlanta Headend without DM Network CherryPicker

A Multiple Decode Receiver (MDR) or IRT receives, demodulates and decrypts the L-band signal. The QAM re-encrypts and upconverts the signal into RF using a 6 MHz channel. The RF signal is sent to the subscribers’ set-top boxes. Only one input feed goes to the output.

Figure 1-7 Scientific-Atlanta Headend with DM Network CherryPicker

Several MDRs or IRTs receive the L-band signal, demodulate and decrypt it. The DM Network CherryPicker then grooms multiple programs and may remultiplex programs before sending the new output program downstream to the QAM modulator. The QAM re-encrypts and converts the signal into RF using a single 6 MHz channel. The RF signal is sent to the subscribers’ set-top boxes. Multiple input feeds go to the output.

Optimizing Bandwidth Utilization

Before we begin to discuss the tools that the DM Network CherryPicker Software 4.1 gives you to optimize your bandwidth, let’s review a few basic digital video concepts.


Digital Concepts

Digital data is information stored as ones and zeros. Digital video is the chrominance, luminance and temporal information that creates a moving picture stored digitally, as ones and zeros. If we were to digitize video without compressing the information, it would take roughly five cable channels to show just one program. Since this is far from practical, a standardized way of compressing video and audio was devised by the Moving Pictures Expert Group (MPEG). MPEG standards come in a variety of flavors defined for specific uses. MPEG-2 was developed specifically for broadcast quality transmission.

If you look at two adjacent frames of film, most of the information in the first frame is repeated in the second frame. Rather than record all of the information in both frames, MPEG encoders record the first frame as a reference frame and then only record the new information from the second frame.

Figure 1-8 Video Frame Compression

The first frame is encoded as a reference picture, called an I-frame. The second frame is encoded by storing only the new information. In the second frame, the background is unchanged, only the position of the plane is new. Since the rest of the information can be inferred from the reference frame, the encoder does not waste space storing redundant information. This means, however, that the second frame cannot be recreated at the decoder without information from the reference frame.

MPEG-2 streams are compressed, or encoded, as separate video and audio streams, called elementary streams. Streams are encoded at bit rates determined by the encoder. The higher the bit rate, the more information is stored. The more information that is stored, generally speaking, the better the video quality will be at the decoder.

Constant Bit Rate Streams

Constant bit rate streams are encoded at a set bit rate regardless of the amount of information that needs to be stored. If there is not enough video information to fill the allotted bandwidth, the encoder simply fills the rest of the stream with null packets. If there is too much information for the given bit rate, quality is compromised.

* Each picture can be compressed independently.* Adjacent pictures tend to be very similar.* Some pictures are encoded as reference pictures.* Other are encoded as differences relative to the reference.


Variable Bit Rate Streams

Variable bit rate streams take into account that some content is simple to encode, requiring only a low bit rate, and other content requires a high bit rate to capture enough of the relevant information. The encoder adjusts the bit rate to match the complexity of the content within a set bit rate range. Variable bit rate streams do not use null packets to fill the stream to a constant bit rate.

Multiplexed Streams

Once the audio and video elementary streams have been encoded, they are multiplexed together to create a Single Program Transport Stream (SPTS), otherwise known as a digital service. When multiple services are multiplexed together, the result is a Multiple Program Transport Stream (MPTS), commonly referred to as a transport stream.

Figure 1-9 Components of a Transport Stream

Several factors impact the number and quality of services that can be carried on a given channel:

• available bandwidth• desired picture quality• CBR vs. VBR sources

Available Bandwidth

Your first consideration is your available output bandwidth. In the United States and Japan, channel bandwidth is generally 6 MHz per channel. In Europe, channel bandwidth is generally 8MHz per channel.

Channel Bandwidth Bandwidth over 6 MHz

US & Japan 6 MHz 64 QAM (26.94 Mbps)

256 QAM (38.77 Mbps)

Europe 8 MHz 64 QAM (38.77 Mbps)

The figure below shows available bandwidth for Motorola and Scientific-Atlanta headends. Motorola offers two different modulators, one that provides 64 QAM and another that provides 64 or 256 QAM. The Scientific-Atlanta QAM modulator can be programmed to either 64 or 256 QAM.

Picture Quality

With video compression, it is possible to squeeze an almost limitless number of streams into a given bandwidth channel. The trade-off, however, between the number of streams delivered and picture quality is steep. The amount you can compress a stream without degrading the video quality depends on a number of factors.

Complexity of Video Content

One consideration when working with bit rates is the difficulty of the content. The more items that are on the screen and the more those items are moving, the more difficult it is for the image to be encoded. The more information that the encoder needs to capture, the higher the bit rate required to keep the video quality high. Sporting events, for example, have many players on the field and many details moving quickly in the background. Sporting events, therefore, typically require a higher bit rate. Programs with relatively slow moving, simple content such as situation comedies can often be encoded at far lower bit rates without significantly effecting the quality of the image.

Quality of Previous Encoding

The original source of the content, as well as the amount of compression prior to transmission, also effects the amount the bit rate can be reduced. Content that originated in the digital domain often has fewer artifacts from conversion and can be more easily compressed, whereas content that has gone through several conversions prior to transmission may degrade more quickly. If the content has already been highly compressed prior to transmission, there will be less compression that can be done without significantly effecting the picture quality.

Number of Non-Video Elements

Non-video elements such as audio and data streams are never recoded by the DM Network CherryPicker. Adding non-video services to the multiplex does, however, reduce the bandwidth available for video content. The more data that travels along with a video stream in a given channel, the more the video needs to be compressed.

Modulator Bandwidth over 6 MHzMotorola IRT 64 QAM (26.94 Mbps)

MPS 64 QAM (26.94 Mbps)256 QAM (38.77 Mbps)

Scientific-Atlanta QAM 64 QAM (26.94 Mbps)256 QAM (38.77 Mbps)


Constant Bit Rate Sources

Constant bit rate streams are encoded at a static bit rate regardless of video complexity. The stream shown above consumes 6 Mbps bandwidth.

Figure 1-10 Multiplexing CBR Streams

If you multiplex several CBR streams together using an Add/Drop multiplexer, the resulting stream will likely be inefficient since the stream will likely be padded with null packets.

Variable Bit Rate Sources

In variable bit rate streams, the bit rate is assigned according to the scene complexity.

Figure 1-11 Multiplexing VBR Streams

VBR streams are more efficient, especially when multiple VBR streams are multiplexed together. The DM Network CherryPicker accepts VBR streams at bit rates from 0 to 20 Mbps.

Rate shaping is the process of changing or altering the bit rate of the service to a lower bit rate in order to squeeze more programs and/or services into the available bandwidth.

Figure 1-12 DM Network CherryPicker Rate Shaping

8 Mbps 4 Mbps



The DM Network CherryPicker can rate shape video to a lower bit rate using five different schemes:

• CBR to CBR• CBR to VBR• VBR to VBR• CherryPruning• Statistical Multiplexing Priorities

High CBR to Lower CBR Conversion

Constant bit rate streams are often encoded by service providers at predefined bit rates that may be higher than necessary for good video quality. Once the service provider’s encoder captures the video content, it will then stuff the stream with null packets to keep the bit rate constant.

When these constant bit rate streams arrive at your headend, you can use the DM Network CherryPicker to strip the null packets from these streams, saving bandwidth without compromising video quality. You can choose to strip some of the null packets and reduce the bit rate to a lower constant bit rate, or you can strip all of the null packets and reduce the bit rate to a lower variable bit rate.

CBR to VBR Conversion

With the DM Network CherryPicker, you can convert constant bit rate input to variable bit rate output in order to optimize channel bandwidth.

Figure 1-13 CBR to VBR Conversion

As shown in Figure 1-13, the CBR feed is compressed slightly at the point where the combined bit rate of the feeds exceed the available 27 Mbps in order to give bandwidth to higher priority feeds.

If the CBR stream contains null packets, the DM Network CherryPicker removes the null packets to reduce the bit rate without effecting the video quality. If the CBR stream


does not contain null packets, the stream is recoded at a slightly lower bit rate until bandwidth is available. The stream that was originally CBR, is now VBR.

High VBR to Lower VBR Conversion

Variable bit rate streams can also be re-encoded to a lower bit rate using the DM Network CherryPicker Software 4.1.

When the combined bit rates of the streams in a multiplex total more than the available bandwidth, the DM Network CherryPicker re-encodes the video portions of those streams.

Figure 1-14 Sample Compression of Three VBR Streams

In the figure above, if the available multiplex bandwidth is exceeded by 3%, then given that each of the three streams has been assigned an equal priority, each program stream is compressed by approximately 1%.

CherryPruning

CherryPruning is a special case of rate shaping where the bit rate ceiling of a particular service is limited. CherryPruning is very useful in xDSL or fixed bandwidth environments.


CherryPruning takes peaks that exceed the designated bit rate and smoothly rate- shapes them. Rather than simply truncating the peak, the DM Network CherryPicker recodes the stream slightly before and after the peak.

Figure 1-15 Compression of Bandwidth in CherryPruning

The figure above shows two points where the stream bit rate exceeds the 3 Mbps ceiling. The peaks are smoothed, or CherryPruned.

Setting Stream Priorities

The DM Network CherryPicker Software 4.1 allows you to prioritize compression by individual program so that only the programs you select are affected. By setting priorities, you are telling the DM Network CherryPicker which streams can be re-encoded and which should be left alone.

You can set priority levels for each service. Services assigned a lower priority (1-5) are recoded before services assigned a higher priority (6-10). Services assigned Do Not Recode priority (11) will not be recoded.

Setting priorities is useful for controlling high bit rate streams that are crowding the output multiplex. By reducing the priority of an input stream, you give DM Network CherryPicker Software 4.1 the ability to reduce the bit rate of a high bit rate stream only at times when it becomes necessary. This preserves the quality of the stream more efficiently than reducing the bit rate of the entire stream by setting a maximum bit rate.

Configuration Files

DM N

This chapter covers:

• the Configuration file- editing the Configuration file- configuring MPEG tables- configuring DVB SI tables- configuring user-specific tables- configuring PSIP tables- configuring other parameters- grooming from the Configuration file- loading example Configuration files- applying Configuration files- saving Configuration files to a different directory- exporting Configuration files

• the cp-controller.properties file- modifying the cp-controller. properties file- grooming to Black or PostBlack files- turning debugging on and off- turning analysis on and off


Configuration Files

The Configuration file defines basic system parameters such as common program clock reference, output table type and program map table.

This is most valuable when you install multiple headends. Rather than going through the same steps to setup several systems, you can create one Configuration file and apply it to all of the systems.

In most circumstances, you edit the Configuration file once during the initial system setup, after you make modifications to the cp-controller.properties file. However, if you do make changes to a Configuration file and apply the new file to a single output multiplex, the changes do not affect the other output multiplexes.

The Configuration file that is currently in use is always stored in the /data/Config directory.

MPEG Terms and Concepts

Before opening a Configuration file, it is important that you are familiar with some basic MPEG terms and concepts.

PAT, PMT and PESs

Figure 4-1 shows how the PAT, the PMT and the PESs are related and the different numerical identities for the same programs:

• PAT links the Program # (MPEG number) to the PMT number.• PMT links the stream type (audio, video, data) to the PES.

Term DescriptionTransport Stream A transport stream consists of one or more programs that are

uniquely identified and configured for distribution to subscriber set-top boxes.

MPEG Service Number

The MPEG Service Number (also known as Service or Program Number) is originally assigned by the broadcaster and uniquely identifies the program service.

Program Clock Reference (PCR)

The Program Clock Reference (PCR) parameter sets the PCR PID and interval. You can specify inserting the PCR either in the multiplex as a separate PID, or embedded in the video/audio stream. To configure the PCR, see “Program Clock Reference (PCR)” on page 4-6.

Packet Identification (PID) Number

Packet Identification (PID) numbers uniquely identify each elementary stream in an MPEG multiplex. There are several Configuration files that configure each DM Network CherryPicker and the programs are identified in each table by their unique PID.


• PES table links the elementary streams to a PID.

Figure 4-1 Relationship Between the PAT, PMTs and PESs (Motorola)

Program Association Table (PAT)

The PAT lists all services that belong to a transport stream.

Figure 4-2 Program Association Table Example

• PAT Packet ID (PID) is always 0.• Program # column lists the MPEG Service numbers.• PMT PID column lists the unique number that identifies the PMT.

Program Map Table (PMT)

Each program has one Program Map Table (PMT) that defines which elementary streams comprise the program. There is one PMT per service, but there may be more than one PMT per PID.

The MPEG specification allows these numbers to vary. Motorola systems use different elementary stream types than other systems. Use the following values to indicate elementary stream type:

Editing the Configuration File

The following sections describe the CherryPicker Configuration file and how to change the parameters defined within it.

To edit a Configuration file:

1. Open the Configuration file using the DM Network CherryPicker Desktop File Editor window.

2. Find the line that sets the parameter and make necessary edits.

3. Save the new file.

4. Apply the edited Configuration file, refer to “Loading Example Configuration Files” on page 4-15.

Configuration File Conventions

The following conventions apply to reading and editing Configuration files:

• Configuration files are text files• # at the start of a line indicates the line is a comment, not a setting - remove the #

from the line to make the line active• quotation marks (" ") surrounding names are required• carriage returns in the middle of a line are not allowed;

do not press the Enter key when editing a line• all numbers are decimal numbers• all tables in HEX are converted to ASCII, in lower case characters• all intervals are in milliseconds

Configuring MPEG Tables

Output Table Type

The Output Table Type identifies the type of output program expected for the QAM type and set-top box.

Program Association Table (PAT)

The PAT command contains three parameters that may be adjusted: interval, transport stream id and NIT PID.

Command ExampleOutput Table Type Type <table type> Type 1

Type Description0 DigiCipherII

1 Basic MPEG-2 systems (PAT and PMT only)

2 DVB (SI table output)

PAT 100 9 16 EXTRA_PROGRAM 22 869


Program Clock Reference (PCR)

The Program Clock Reference (PCR) parameter sets the PCR PID and interval.

Specify the PCR to be inserted in the multiplex as a separate PID or to be embedded in the video/audio elementary stream depending on the requirements of your system’s set-top boxes.

Input PID Passing

The PASS parameter enables you to pass PIDs through the DM Network CherryPicker without changing the bit rate.

Add one line per PID to the Configuration file, using the form:

Command ExamplePCR PCR <pid> <interval>

(If PID is -1, video or first audio PID is used.)(PCR insertion interval can be 16-500ms.)

PCR -1 90

Command ExampleInput PID PASS <inputLine> <inputpid> <outputLine>

<outputpid> [<tableID> <tableIDExtension>] PASS B1 4094 A1 4094 197 -1

PSIP Example: PASS C2 8187 D3 8187 197 -1

Parameter Parameter DescriptioninputLineinputpidoutputLineoutputpid

Optional:tableIDtableIDExtension

Physical input line (upper case).Input PID or NIT PID.Physical output line.Output PID (does not have to match inputpid if input is program).

Table ID for PASS element.TableIDExtension (usually program number).

NOTE

The output PID must match the NIT PID specified in the PAT command if it is an NIT table being passed to enable Motorola encryption.


Program Map Table (PMT)

The PMT defines each elementary stream of each program.

The stream section (streamType, streamID, reserveVideoRecoders can be repeated as needed for multiple video or other stream support.

Add one line per program to the Configuration file, using the form:For non-video stream

NOTE

If you specify tableID and tableIDExtension, the PID with that table ID and table extension are passed. If you do not specify tableID and tableIDExtension parameters, all packets with specified PID are passed.

If you need to send the complete PID from an incoming stream, do not specify tableID and tableIDExtension parameters.

NOTE

If the NIT PID and the table ID are incorrect, the wrong PID will pass through the DM Network CherryPicker unencrypted.

Command ExamplePMT <PMT> <program_number> [POOL <"name">]

PMT PID PID of program map table for specified output program.

program_info_length Program descriptor length.

program_descriptors Number of bytes of data to inject in PMT. For Motorola, refers to CA descriptors. If if programInfoLength length is 0, parameter is omitted.

stream_type Indicates stream is video, audio, or data.

stream_info_length Stream descriptor length.

elementary_PID PID of stream.

reserve_video_recoder(if stream type is video)

NoRec Do not reserve a recoder.


PMT Repetition Rate

The PMT Repetition Rate specifies the interval between PMT insertions.

Configuring DVB Service Information (SI) Tables

DVB SI tables provide information about the programs that comprise the transport multiplex. SI tables allow the programs to have names, allow service delivery information to be provided and electronic program guide information to be transmitted.

Network Information Time (NIT)

The NIT provides synchronization timing for DVB requirements or for encrypted MPEG program streams so that the individual inputs are properly synchronized for output.

Service Description Table (SDT)

In DVB headends, SDT lists the names and other parameters such as language codes, running status and country availability of the services within the transport stream. There is a different SDT sub-table for each transport stream.

SDRec Reserve an SD recoder.

HDRec Reserve an HD recoder.

Time and Date Table (TDT)

In DVB headends, TDT transmits the actual UTC-time coded as Modified Julian Date (MJD), for synchronizing the internal clock of an IRD.

The example DVB Configuration file does not include TDT, but does include the TDT rate.

Configuring User-Specific Tables

In some headends, the following tables do not need to be inserted because they are inserted by third party equipment. For other headends, however, you may need to configure the following table:

Conditional Access Table (CAT)

The CAT controls the scrambling of a service. It contains a pointer to provider-specific conditional access information.

Configuring PSIP Tables

ATSC PSIP tables include System Time Table (STT), Master Guide Table (MGT), Cable Virtual Channel (CVCT), Terrestrial Virtual Channel Table (TVCT), Rating Region Table (RRT), Event Information Table (EIT) and Extended Text Table (ETT).

DM Network CherryPicker Software 4.1 generates STT, MGT, RRT and CVCT based on information provided by the user and by the groomed programs. Whenever an output multiplex is configured as an ATSC multiplex, the PSIP tables (except for ETTs and EITs) are inserted into the multiplex regardless of whether they are present at the groomed input. The EITs and ETTs are inserted only if specified. By default, four EIT instances are inserted for each groomed program. DM Network CherryPicker Software 4.1 preserves the general input PSIP information, but may modify the numerical value in order to make the output table compliant with PSIP standards. For example, it may be necessary to change the major and minor channel numbers.

One EIT consists of several instances. Each instance contains all events for a particular program for a 3-hour interval. An event is a collection of elementary streams with a common time base, an associated start time, and an associated end time (the equivalent

Table Command ExampleCAT CAT <interval> <table>

(CAT insertion interval can be 16-10000ms, typically 9000.)

CAT 9000 01802300001f0...


of a complete television program). DM Network CherryPicker Software 4.1 modifies and passes the input EIT and ETT to the output.

One ETT also consists of several instances. Each instance contains one Extended Text Message (ETM) which refers to either an individual program (channel ETT) or to an individual event (event ETT). For example, assume that a transport stream has 10 programs and each program has six events in a 3-hr. interval. This transport stream may contain up to 10 instances of the EIT (for this time interval), plus 10 instances of the channel ETT, plus 10x6 = 60 instances of the event ETT. The PSIP standard specifies that the EITs/ETTs may be defined for up to 128 3-hr. intervals (16 days), which may result in quite a few instances. DM Network CherryPicker Software 4.1 supports up to eight EITs/ETTs (24 hours).

Table Intervals

To set intervals at which tables are sent:

NOTE

When the output is configured as ATSC, only the STT is inserted. The MGT and CVCT are not inserted until a program is groomed. The RRT is inserted only if it is defined in the Configuration file. The ETT is inserted only if it is present at the input.

NOTE

PSIP support is enabled via license keys on a per output multiplex basis. See “Enabling Features with License Keys” on page 3-7 for more information.

Table Command ExampleMGT MGTRATE <rate>

(MGT insertion interval can be 16-150ms, typically 135.)

IMPORTANT

If input feeds are specified in the Configuration file, it is very important to connect the correct feeds to the inputs specified. Since the inputs are pre-labeled in the Configuration file, connecting an input which has MPEG numbers other than those expected may cause confusion.


Creating Output Programs

Output programs are defined in the Configuration file. In the example below, each line represents an output program. There are four output programs associated with this output mux. To add additional output programs, add more lines using the same syntax.

PMT 1 1000 0 2 1001 0 SDRec 4 1002 0 4 1003 0 192 1004 0PMT 2 1005 0 2 1006 0 SDRec 4 1007 0 4 1008 0 192 1009 0PMT 3 1010 0 2 1011 0 SDRec 4 1012 0 4 1013 0 192 1014 0

PMT 4 1015 0 2 1016 0 SDRec 4 1017 0 4 1018 0 192 1019 0

Assigning Black and PostBlack Files to Specific Output Programs

Use the following command to define the name of a black file or post black file to be used in a specific output program. This command defines the name of a file to be used in a specific output program. This command, if present, overrides the file name given in BlackFile for this particular output program:

IMPORTANT

If you plan to name programs and groom via the Configuration file, be sure that the naming commands appear before the grooming commands. The Groom command must be below the PMT command section in the Configuration file.

NOTE

The maximum number of programs is 94.

Modifying Subtitle Parameters

If the video stream contains subtitle information, the subtitle information is groomed along with the rest of the stream.

Grooming from the Configuration File

Adding groom commands to the Configuration file can speed up grooming at system start up, because you do not have to manually groom all the channels via the DM Network CherryPicker Desktop software.

You can set up groom commands by ID or by name:

Grooming to Black

When Groom to Black is selected in the Grooming window, a black video file is played from the DM Network CherryPicker until another groom command is sent. Which file is played can be auto-detected per stream or defined globally.

Auto-detect Frame Size

If you leave the black file set to the default file "black", the video size of the last groomed output stream is automatically detected and a black file of the same video size is played.

Define a Specific File for Black

You can define a specific video file stored in the /usr/cp/video directory to use as the file played when Groom to Black is selected.

Use the following command in the cp-controller.properties file to define a black file:

Grooming to PostBlack

When a Splice_Request message is received from an Ad Server where the PostBlack field is non-zero, a black video file and a muted audio file (together known as PostBlack) are played at the end of the insertion.

NOTE

In PAL territories, use the default file name "black" (rather than black.pal) to allow automatic detection.

Command Parameter Parameter DescriptionBlackFile=<file_name> file_name Name of the black video file.

NOTE

If you specify the black file to use in the cp-controller.properties file, the file is specified for the entire device and is not stream dependent.


Auto-detect Frame Size

If you leave the postblack file set to the default file "postblack", the video size of the groomed stream is automatically detected and a postblack file of the same video size is played.

Define a Specific File for PostBlack

You can define a specific video file stored in the /usr/cp/video directory to use as the file played when Groom to PostBlack is selected.

Use the following command in the cp-controller.properties file to define a postblack file:

Enabling Debugging

The debugging function allows you to help Terayon Technical Support gather data to troubleshoot difficult problems. By default the debugging function is disabled. Enabling debugging is a temporary action that should be executed only at the request of Terayon Technical Support.

The debug software writes two files to the \usr\cp\Debug directory:

- FarmerError

- FarmerOut

NOTE

In PAL territories, use the default file name "postblack" (rather than postblack.pal) to allow automatic detection.

Command Parameter Parameter DescriptionPostBlackFile=<file_name> file_name Name of the post black video file.

NOTE

If you specify the postblack file to use in the cp-controller.properties file, the file is specified for the entire device and is not stream dependent.

Command Parameter Parameter DescriptionDebug=<value> value 0=debugging off

2=debugging on4=debugging on


Regardless of whether debugging is enabled or not, the software automatically writes additional files to the host that may help with troubleshooting.

- gui.out contains any GUI debugging messages.- gui.err contains any JAVA exception or error messages from running the GUI.

The GUI diagnostics files each have a size limit of no more than 1 MB. The software writes messages alternatively to filename.v1, then (once the file is full), to filename.v2. When the second file is full, the software goes back to writing to filename.v1. Only one file, either .v1 or .v2 exists at any one time.

If you are running Windows 2000, these files are stored in the C:\Documents and Settings\username directory.

If you are running Windows NT. these files are stored in the C:\winnt\profiles\username directory.

Turning Analysis On and Off

Analysis is a valuable tool to help you optimize the performance of your DM Network CherryPicker. When the analysis screens are not in use, however, it can be turned off to release system resources to other tasks.

NOTE

You can reduce the number of error messages the debug function issues by locating the line RepeatErrorSquash=Off and editing it to On. With this function on, only one of the same error messages is generated per hour.

Configuration Tree

The Configuration tree is a hierarchal list that gives you access to the hardware configuration and stream elements passing through your system.

To access the Configuration tree:


Figure 5-1 Configuration Tree


Controller

The Controller is generally the highest level of the Configuration tree. If you are controlling multiple DMs from a single GUI using Master Control™, the DM will be the highest level.

Configuring the Controller

Configuring the Controller consists of entering the IP address of the NTP Server, if applicable.

To configure the Controller:


2. Select the Controller from the configuration tree. The Controller information displays on the right side of the screen.

Figure 5-2 Controller Properties

ID Displays Controller ID. Default is the hardware serial number.

Name Displays Controller name. Default is the hardware serial number. To modify the name, refer to “Devices” on page 5-6.

Mode Displays mode. Only mode available in this software release is Independent.


3. Make any required changes and click Apply.

Sites

A Site identifies a headend location where a DM Network CherryPicker is installed, or a region that a particular DM Network CherryPicker services. In Independent mode, a Controller can only have one Site which is automatically created.

IP Address Displays the IP address of the DM Network CherryPicker. The IP address must be set at the time of installation via the hardware front panel display. Refer to the "DM Network CherryPicker Hardware Installation and Front Panel Guide" for instructions.

NTP Server Address Enter the IP address of the Network Time Protocol Server as appropriate.

Software Version Displays the software version currently running.

MAC Address Displays the MAC Address.

Model Displays the DM Network CherryPicker hardware model.

Connect If you are using Master Control™ and one of the member DMs goes down, click the Connect button to reestablish the connection.

Create Site Click to create additional Sites. Refer to “Sites” on page 5-4

Reboot Reboots the DM Network CherryPicker hardware taking services down on all outputs during the reboot process. When the device stops, it looses grooming and other configuration settings. When it restarts, the device regains the configuration settings that existed prior to stopping the device. Required for software updates and troubleshooting. Reboot process takes 1-2 minutes.

Restart Restarts the DM Network CherryPicker software without rebooting the hardware. When the device stops, it looses grooming and other configuration settings. When it restarts, the device regains the configuration settings that existed prior to stopping the device. The restart operation takes about 15 to 20 seconds. This option is useful for applying changes to the cp-controller.properties file.

IMPORTANT

The DM Network CherryPicker outputs no data on any port during reboot.

Remove Not applicable for Independent mode. Reserved for Master/Slave mode which is not supported in this software release.


3. If you have changed the name of the Device, click Apply to make the change.

Input Feeds

The DM Network CherryPicker automatically senses input connections and displays them in alphabetical order of their slot ID. Because each Input Feed represents a physical input, you cannot manually create an Input Feed.

- Each input is automatically sensed and labelled [Active] or [Not Responding].- Stream PID is displayed next to the stream name.- One physical line corresponds to one MPEG signal (logical) input. - DM Network CherryPicker Software 4.1 supports 17 signal inputs (17 input MPEG trans-

port streams).

Replace Not applicable for Independent mode. Reserved for Master/Slave mode which is not supported in this software release.

Reboot Reboots the DM Network CherryPicker hardware taking services down on all outputs during the reboot process. When the device stops, it looses grooming and other configuration settings. When it restarts, the device regains the configuration settings that existed prior to stopping the device. Required for software updates and troubleshooting. Reboot process takes 1-2 minutes.

Restart Restarts the DM Network CherryPicker software without rebooting the hardware. When the device stops, it looses grooming and other configuration settings. When it restarts, the device regains the configuration settings that existed prior to stopping the device. The restart operation takes about 15 to 20 seconds. This option is useful for applying changes to the cp-controller.properties file.

NOTE

One recoder is capable of recoding either one HD video stream or 4 SD video streams. Reserving one HD recoder therefore removes 4 SD recoders from the pool of available recoders. To reserve recoders, refer to “Output Multiplexes” on page 5-28.

Input Multiplexes

An Input Multiplex is shown as the level of hierarchy under an Input Feed.

Creating Gigabit Ethernet Input Multiplexes

Unlike other modules, enabling a Gigabit Ethernet module does not automatically create associated Input Muxes.

Gateway Enter a gateway address. No gateway is necessary if all devices are on the same subnet.

Transceiver Type Select Optical or Electrical.

Loop Through Enabling this setting sends all Ethernet frames (MPEG and non-MPEG) from the input port to the output port on the same Gigabit Ethernet module.

MAC Addr. Filtering Turning this setting to On allows the physical layer of the Gigabit Ethernet input port to accept only the Ethernet frames addressed to this interface. Turning this setting to Off allows the physical layer to accept all incoming Ethernet frames (MPEG and non-MPEG).

NOTE

You will not see an Input Mux under the Gigabit Ethernet Input Feed until you create one.

IMPORTANT

To change the IP address that has been assigned to a Gigabit Ethernet port requires disabling the port, then re-enabling the port and assigning the new IP address. Since disabling the port deletes any multiplexes that have been created, it is recommended to export the Configuration files assigned to the multiplexes prior to disabling the port.

NOTE

The maximum number of input multiplexes is 200. The same limit applies to both a single input port and a device as a whole. This limit applies to both GigE and non-GigE inputs.

Clearing an Input Multiplex

When connecting a new Input Feed or changing from one source to another, it is important to clear the input multiplex. When the DM Network CherryPicker loses an input it, it assumes that a new input is the same as the last. This is done so that services can be recovered more quickly if a feed goes down.

ID Displays the Input Mux ID. Default is the port ID.

Name Enter a name for the input multiplex. Default name is Input <slot> <port>.

Clear Clears the multiplex. Refer to “Clearing an Input Multiplex” on page 5-15 below.


To clear an input multiplex:

If you have an Input Preprocessing module installed and a valid software license, you will see an Input Preprocessing button in the Input Mux properties panel.

Figure 5-13 Input Mux Properties with Input Preprocessing

The Input Preprocessing module supports horizontal resolution changing of SD video streams. The table below lists available horizontal resolution changes.

Input Horizontal Resolution Available Horizontal Output Resolutions720 704, 544, 528, 480, 352

704 544, 528, 480, 352


Input Preprocessing

- The original input video stream PID and PES headers are preserved. - If a PCR is carried on the video stream PID, it is preserved.- Streams with horizontal resolution exceeding 720 pixels or

vertical resolution exceeding 576 lines are pass through unchanged.- If the original input stream resolution is less than the requested output resolution,

the stream passes through unchanged.- Processed data can be output on any output module.- The modified stream resolution is displayed in the Program/Stream Analysis screens.

Program Mode

If the Input Mux is not an Ad Feed, resolution change is associated with a program. If the video PID changes, resolution change will continue and will be applied to the new PID.

The Input Preprocessing window displays a column labeled Program.

Figure 5-14 Input Preprocessing - Program Mode

PID Mode

If the Input Mux is an Ad Feed, resolution change is associated with an individual PID. In ad insertion, since the ad PID may not be continually present, the ad PID is tracked so that resolution change will only be applied to that PID.

4. Click Add Multiplex. For information regarding Add Multiplex, refer to “Gigabit Ethernet Output Multiplexes” on page 5-28.

Mode Select to enable/disable the Gigabit Ethernet module. - Ports can only be enabled with a valid license key. - If the port is disabled, all input and output multiplexes associated with the port are deleted and the corresponding groomed streams are dropped.

MAC Address Displays the MAC Address of the Gigabit Ethernet port.

IP Address Enter a static IP address for this port (1.1.1.1 to 223.255.255.255, except 127.X.X.X which is reserved as the loopback address for troubleshooting).

Net Mask Enter a net mask address.


Transceiver Type Select Optical or Electrical. If Optical is selected, optional SFP connectors must be installed into the port.

MPEG Packets Select the number of MPEG transport packets to output per Ethernet frame. Default is 7 (which results in fewer headers thereby giving the best bandwidth utilization), but downstream equipment capabilities must be taken into consideration.

MPEG Output Select Active (Default) or Standby.

Active - output port operates normally, transmitting MPEG packets.

Standby - all multiplexes and grooming that exist at the output port prior to the switch to this state are preserved. The output port does not send any MPEG packets, however, it is still able to send regular, non-MPEG Ethernet packets (such as various IP protocol management packets, etc.). All operations available for a normal output, such as creation and deletion of multiplexes, grooming and dropping of grooming, etc. is allowed for a standby port.

Transition from the standby state to the active state automatically restores the configuration and grooming of multiplexes at the output port.

IMPORTANT

Configuring the Gigabit Ethernet settings can be done by changing the parameters of either the input feed or output port. In either case, the parameters of the entire port, both input and output, will change.


Configuring DVB-ASI or DHEI Output Feeds

Output Multiplexes

An Output Mux icon is shown as the level of hierarchy under an Output Feed. If there are no output programs groomed to this Output Mux, the Output Mux icon is gray.

Gigabit Ethernet Output Multiplexes

Gigabit Ethernet Output Muxes are distributed over Gigabit Ethernet networks using either unicast or multicast protocols. Downstream equipment such as edge QAM devices, ingest devices for PVR functionality, TSI-equipped or alternate DM Network CherryPickers can then acquire the multiplexes for their own use.

Gigabit Ethernet Output Muxes can be configured in several ways. Depending on the settings that you select when creating the multiplex, they can be passed through the DM Network CherryPicker unchanged or they can be altered by the DM Network CherryPicker (using rate shaping or ad insertion).

Rate Shaped Multiplexes

This category of output multiplexes takes advantage of the DM Network CherryPicker’s ability to process the input stream in order to change the bit rate or enable ad insertion.

- Rate shaping of SD/HD streams is available.

NOTE

Make sure that the Total Line Rate displayed is not more than the available bandwidth of your system.

When the downstream device is a Sencore ATSC987 Modulator, set the DVB-ASI Total Line Rate to 19.3926 Mbps.

Ad Insertion


- Ad insertion of SD/HD streams is available.- Null packet padding is selectable.- Output tables are fully regenerated using the Configuration file selected.

GigePipe Aggregation Multiplexes (Non Rate Shaped)

There are two types of GigePipe Aggregation Multiplexes - Aggregation and Mux Forwarding. Both types allow you to pass streams to a Gigabit Ethernet output port unchanged and with minimal latency.

Aggregation Multiplexes

Aggregation multiplexes send selected streams or programs from various inputs to a specified output port for distribution via a Gigabit Ethernet network. The main application of Aggregation multiplexes is to combine streams from different inputs into a single output multiplex and forward it to a secondary headend.

- Rate shaping is not available.- Ad insertion is not available.- Output tables are fully regenerated using the Configuration file selected.

Mux Forwarding Multiplexes

A Mux Forwarding multiplex distributes the entire multiplex, without changes, over the Gigabit Ethernet network for use by other equipment present on the network. The main application of Mux Forwarding multiplexes is to take a full input source, such as a 27

NOTE

A GigePipe Aggregation software license is required to enable this feature.

GigePipe Aggregation multiplexes are not supported on the DM 3200.

Mbps satellite transponder at a master headend, and forward it to secondary headends. Grooming a Mux Forwarding multiplex thereby makes an entire satellite feed available on the entire Gigabit Ethernet network.

- All MPEG packets belonging to an input LMN are forwarded to any output LMN.- All incoming MPEG packets (encrypted and non-encrypted streams and tables) are for-

warded to the output multiplex and encapsulated in a unicast or multicast stream.- No tables are processed since all input PIDs and PSI tables are forwarded to the output.- No Configuration file is associated with this type of multiplex.

Maximum Output Multiplexes

The maximum number of output multiplexes per device is 128.

In addition to this overriding limit, there are limits to the maximum number of multiplexes of a particular type.

Configuring a Rate Shaped Multiplex (SPTS)

The following example results in sending a 3.75 Mbps constant bit rate with null packet padding SPTS multiplex to a UDP destination port using unicast.

1. Select a Gigabit Ethernet Output Feed from the Configuration tree.

Output Rate Control - Stat Mux Pools

The DM Network CherryPicker allows you to group several output multiplexes and set a maximum aggregate bit rate for the group as a whole. This group of output multiplexes is referred to as a Stat Mux Pool. Stat Mux Pools facilitate content distribution from a central headend to hubs where multiple transport streams (MTPS) can be distributed via one physical output channel.

What is included in the aggregate bit rate calculation?

All bytes of a transport stream packet with a certain PID, including video, audio, private data and header bytes, contribute to the bit rate of the component. PSI tables, SI tables and PSIP streams are not included in the bit rate calculation.‘

Go to the File Editor Screen Opens the current Configuration file in the File Editor screen.

Export Exports the Configuration file as a text file stored on the Data Flash is directory /usr/cp/Config.

NOTE

Stat Mux Pool support is enabled via license keys on a per output multiplex basis. See “Enabling Features with License Keys” on page 3-7 for more information.

IMPORTANT

Reserve an appropriate amount of overhead for any SI and PSI tables that will be re-generated downstream from the DM by external devices. SI and PSI tables included in the output multiplex are not accounted for in the rate control of each pool. A rule of thumb is to reserve 0.3 Mbps for 64 QAM and 0.5 Mbps for 256 QAM.

IMPORTANT

Every program in a Stat Mux Pool enabled multiplex must belong to a Stat Mux Pool. A maximum of 8 pools can be created per multiplex.

Every program in a Stat Mux Pool can only belong to one Stat Mux Pool. The same program cannot belong to two different pools simultaneously.

NOTE

Enabling a Primary Output port requires a DVB-ASI Output Port license.

A maximum of eight 4xDVB-ASI output ports can be configured per chassis.


You will not be able to configure any settings since the mirrored port is an exact replica of the primary output port being mirrored.

Loopback Capability

Primary output ports and mirrored output ports on 4xDVB-ASI modules have loopback capability. Loopback ports are indicated by the label [Loopback] in the Configuration tree.

Figure 5-47 Loopback Capability

When programs are groomed from a primary or mirrored output port, the groomed programs are automatically made available on the loopback port as an input. The programs can them be groomed to another output without taking up valuable input bandwidth a second time.

Loopback input programs can be groomed to any DM output using any of the grooming modes (by program, by stream, custom grooming, etc.).


Figure 5-48 Groomed programs available at loopback port

In the figure above, you will notice that the groomed programs (D1_1 through D1_4) are available as input programs on the loopback port.

Clearing Loopback

A loopback input can be cleared like a regular input port. When you click the Clear Loopback button, the software drops all programs and tables in the loopback input multiplex.

The Clear Loopback button is active only:

- when active programs are available at the input, and - the loopback line is in [not responding] mode.

NOTE

Ad insertion is not supported on loopback inputs.


Using Master Control™

Master Control gives you the ability to see information about any member DM in a group; including configuration, stream analysis, events, and alarm lists, from a single application window. Creating a group of DMs that can be controlled from a single application window gives you the ability to build a Distributed Chassis™ with expandable capacity.

Grooming

DM N

Grooming is selecting specific multiplexes, programs or elementary streams from the input multiplex sent from service providers. You choose, or groom, the programs you want from each input multiplex, then output the new selection of programs as a remultiplexed output stream from the DM Network CherryPicker. In this way, undesired programs do not consume valuable bandwidth, and you can combine multiple input feeds into a single output.

Grooming can be done from any input port (DVB-ASI, DHEI, or Gigabit Ethernet) to any output port (DVB-ASI, DHEI, or Gigabit Ethernet).

5. When the Input Stream is over the correct Output, release the mouse button.


Cross-DM Grooming

Cross-DM grooming refers to grooming programs between members of a master control management console group of DMs. Cross-DM grooming allows you to groom input programs from one DM over a Gigabit Ethernet network to the output of another DM.

Figure 6-5 Cross-DM Grooming from DM #3 to DM #4

We use standards-based IGMP and multicast Ethernet protocols for cross-DM communication.

When you cross-DM groom, the source DM creates a mux forwarding multiplex and broadcasts it over the Gigabit Ethernet network using a multicast address and specified UDP port. The destination DM joins the multicast group via an IGMP join command, receives the program and grooms it to the specified output port. For an explanation of mux forwarding, refer to “Mux Forwarding Multiplexes” on page 5-29.

As long as the DMs are on the same Gigabit Ethernet network, they do not have to be in the same physical location.

Cross-DM Grooming Requirements

Cross-DM grooming requires two or more DMs cabled and configured on the same Gigabit Ethernet network.

• each DM must be a DM 6400• each DM must have a Gigabit Ethernet Input/Output module installed• each DM must have a GigePipe Content Aggregation license• each DM must be a member of the same Managed Group• a cabled Gigabit Ethernet connection must exist between each of the DMs

Setting the Multicast IP for Cross-DM Grooming

In order for the DMs to communicate with each other, you need to assign them IP addresses and subnet masks on the same network prior to cross-DM grooming.

The set the multicast IP address:

1. Login to the Managed Group.

2. Configure the Gigabit Ethernet Input/Output modules for the DMs that will be involved in cross-DM grooming. From the DM Network CherryPicker Desktop menu bar, select Configure.

NOTE

Cross-DM grooming is not supported with Program Redundancy or Passing PIDs.

NOTE

Because IGMP is based on multicast IP (group) only and not address (address includes IP and port), it is important to use a different multicast IP address for each source multiplex for both aggregation and cross-DM grooming. If the same multicast IP address but different ports are used, then upon receiving an IGMP join message, the IP switch forwards all streams that match the multicast IP and may flood the Gigabit Ethernet ports with unwanted streams.


3. Select the Gigabit Ethernet port from the Configuration tree.

Figure 6-6 Gigabit Ethernet Input Port Properties

4. Enter an IP Address and Net Mask that is on the same Gigabit Ethernet network as the other DMs involved in the cross-DM grooming. Do this for all of the DMs involved.

IP Address Enter a static IP address for this port that is on the same network as the other DMs involved in the cross-DM grooming (1.1.1.1 to 223.255.255.255, except 127.X.X.X which is reserved as the loopback address for troubleshooting). Use a different multicast IP address for each source multiplex for both aggregation and cross-DM grooming.

Net Mask Enter a net mask address that is on the same network as the other DMs involved in the cross-DM grooming.



Cross-DM Grooming

Once you properly configure the DMs, the procedure for grooming is the same as if you were grooming within a single DM. The only difference is that the first time you cross-DM groom, you will assign the Forward Multicast IP address.

To cross-DM groom using drag and drop:


Figure 6-7 Drag and Drop Cross-DM Grooming

NOTE

Cross-DM grooming does not support: program redundancy, output PID sharing groups, or grooming to a file.

Cross-DM grooming requires a GigePipe Content Aggregation license (available on DM 6400s only).


2. From the Input side, select the source DM program and drag it to the destination DM on the Output side. The Program Interval window displays.

Figure 6-8 Entering the Forward Multicast IP and UDP Port

3. In the Fwd Multicast IP field, enter the multicast IP that the DMs are using for cross-DM grooming.

4. In the Port field, enter the UDP port the DMs are using for cross-DM grooming.

5. Click OK.

Fwd Multicast IP For Cross-DM Grooming only. Enter the multicast IP address for cross-DM grooming (valid range 224.0.0.0 to 239.255.255.255). Use a different multicast IP address for each source multiplex for both aggregation and cross-DM grooming.

Port For Cross-DM Grooming only. Enter the UDP port used for cross-DM grooming (0 through 65535). Unless required by the downstream device, it is not recommended to use UDP ports in the 0 - 1023 range.

NOTE

Each source multiplex that you are cross-DM grooming requires a unique combination of multicast IP address and UDP port. For example, 237.77.77.77:206 and 237.77.77.77:207.


Custom Grooming

Custom grooming is useful to eliminate elementary streams (video, audio, or data) that are not needed in the output multiplex. Removing these streams from the output multiplex can reclaim valuable bandwidth.

Custom grooming can include:

- one video stream- any number of audio streams- any number of data streams

For example, if the input multiplex has audio streams in five different languages and you only need English and Spanish, use custom grooming to select only the two audio streams you need. You have saved the bandwidth that the extra three languages would have otherwise taken.

To custom groom:

1. From the View/Edit screen, select either the By Schedule or By Program tab, then click New.

2. Select the Input/Output tab, click Custom.

Figure 6-9 Program Interval - Input/Output Tab

NOTE

Custom grooming of elementary streams can also be done by using drag and drop grooming. Refer to “Grooming by Drag and Drop” on page 6-5.


3. Click Settings.

4. Select an Input Program and expand it to show its video, audio and data elementary streams.

Figure 6-10 Custom Grooming - Selecting an Input Program

5. Select an Elementary Stream.Click the arrow pointing left to add elementary streams to the custom Output Program.

Figure 6-11 Custom Grooming - Adding an Elementary Stream

6. Click OK when the elementary streams are added.

7. Click OK again to accept the newly created Program Interval.

8. To add programs, go to "Adding an Input Program to the Output Multiplex" on page 6-21.]

NOTE

The order in which you add audio streams determines which language is primary and which is SAP.


Grooming 4xDVB-ASI Module Loopback Programs

When you groom programs from a 4xDVB-ASI module port, the groomed programs are automatically made available as a virtual input on the loopback port. You can then groom the virtual input programs just as you would groom any other program without taking up valuable bandwidth a second time.

To groom loopback programs using drag and drop:



3. Select an Input Stream to groom from the Input side and drag it to the Output side. The cursor is an Ø icon until the icon is over an appropriate output.

Figure 6-12 Grooming 4xDVB-ASI Module Loopback Programs

4. When the Input Stream is over the correct Output, release the mouse button.



CA Descriptors

The example Configuration files for Motorola headend environments contain an additional parameter called the CA Descriptor. The descriptor, different in each PMT line, is just one parameter of many that allows re-encryption of services at the IRT.

The following is an example of a PMT line:

PMT 1 41 6 090447490029 128 16 0 129 17 0 129 18 0

where 6 is the ECM Descriptor and 090447490029 is the ECM PID. The last four characters of the ECM Descriptor is the Hex value of the PMT PID. Hex(41)=0029.

Each Configuration file has a number of PMT lines by default. If they are not being used, they remain in the Configuration file (commented out with a #) as placeholders until they are needed.

If you use the Setup screen to drag and drop an input to any one of these pre-defined output programs, that program, as defined by the Configuration file, will contain the CA Descriptor.

If you use the Setup screen to drag and drop an input to create a new Output Program, the DM Network CherryPicker software must create a new PMT line which will not automatically have a CA Descriptor. You need to add the CA Descriptor to the new PMT line using the Text Editor and reapply the Configuration file. As with applying any Configuration file, all grooming will need to be redone on the effected DM Network CherryPicker.

Grooming Encrypted Streams

Grooming of encrypted streams is allowed.

The encrypted stream, however, is not actually sent to the output while it is encrypted at the input. The DM constantly monitors the state of the input stream, and when it is in the clear (unencrypted), it is sent to the output. Once in the clear, the stream can be recoded, if specified so in the grooming setup.

Allowing the use to assign specific PIDs to the groomed streams (currently, PID assignment for groomed streams is entirely under the DM control).

Passed PIDs

Tables and elementary streams can be groomed to the Passed PIDs level of an output multiplex. This passes the table or stream directly to the output without processing.

- Both input elementary streams and input PSI/SI streams may be passed to an output. - Passed tables will be listed in the PAT. - Up to 300 streams can be passed.- Passed and groomed streams can coexist in the same output program.


- The same PID can be passed to multiple output multiplexes.- Encrypted elementary streams can be passed.- Cross-DM grooming does not support Passed PIDs.

Passing Tables

Assigning PIDs

For some applications, it is required to assign a different PID to a stream. When grooming a stream or a PMT, you are given the choice of either assigning a PID or letting the software manage PID assignment.

By default, the video PID is assumed to carry the PCR. However, you are given a choice of changing the default PCR PID. If a video stream is absent from the output program, the PCR PID will be assigned to the first groomed stream carrying the PTS/DTS time stamps.

PID Auto This column defaults to the PID the stream had on the Input.

To change the PID, click near the PID number. A field will open for you to enter the new PID.

Select the PID Auto checkbox to let the DM Network CherryPicker select the PID for this stream.


Adding an Input Program to the Output Multiplex

There are four ways to get to this point in the grooming process; grooming by schedule, grooming by program, grooming by drag and drop or custom grooming.

If you are grooming an Input Stream to an Output Program, the Input Stream replaces the existing Output Program (or Output Program placeholder). Since no new Output Program is created, skip to Step 3.

If you are grooming an Input Stream to an Output Mux, a new program is created.

To configure a new program:

1. Once you click the New button from the Grooming Setup or Grooming View/Edit screen, the Create Program window opens.


Name Name of the groomed Input Program.

Service Number ID of the groomed Input Program.

Recoder None Select to not reserve a recoder.

Reserve SDTV Recoder Select to reserve an SD recoder.

Reserve HDTV Recoder Select to reserve an HD recoder.

Select Stat Mux Pool Only available if Stat Mux Pools are being used. Refer to “Creating a Stat Mux Pool” on page 5-39.

Create PID Sharing Group Select to assign the same PID to multiple groomed input programs. Refer to “PID Sharing Groups” on page 6-31.


2. Make desired selections and click Next.

3. The Program Interval window opens.

14. Once all program interval settings are selected, click OK.

Backup Programs

Backup programs can be one of the following:

- an input program- a custom input program (a combination of input elementary streams which are groomed

using custom grooming as a single output program in case of switchover)- a file (as used when grooming from a file)

File Enables switchover to a file.

File Select the file to use as backup program.

Switchover Conditions Primary -->Backup All video/audio streams underflow Enables backup program to switchover only if all video

and audio streams underflow.

Any video/audio streams underflow Enables backup program to switchover if any video or audio stream underflows.

Video underflow duration Defines the length of time the switchover condition occurs on the video stream before the switchover to the backup program takes effect. Min 1 sec (1 sec increments) / Max 1,000 secs.Default 10 secs.

Audio underflow duration Defines the length of time the switchover condition occurs on the audio stream before the switchover to the backup program takes effect. Min 1 sec (1 sec increments) / Max 1,000 secs.Default 10 secs.

Backup -->Primary Return to primary program Selects whether or not the backup program switches

back to the primary program when the switchover condition ends.

Primary pgm error free period Defines the length of time after the switchover condition is no longer active before the primary program is switched back.Min 2 sec (1 sec increments) / Max 1,000 sec.Default 60 secs.


The backup program inherits the grooming settings of the primary program, such as time interval, recoding settings, etc.

Switchover Conditions

When a primary program disappears, the DM automatically switches to the backup program. The primary program is dropped, and the backup input program is groomed to the same output program as the primary program.

The conditions for switching from a primary program to a backup program are:

- The primary program is not listed in a new version of the input PAT.- One or more alarms were raised in all video and audio streams in the program, and at

least one of those alarms is not cleared for a specified time interval.- The number of alarms raised by all video and audio streams in a program during the time

interval is equal or greater than a specific threshold. Note that if a raised alarm is cleared during this interval, it is still counted against this threshold.

The stream types used for a switchover decision are video (MPEG-1 and MPEG-2), and audio (MPEG-1, MPEG-2 audio and AC-3).

If the backup program is absent at the time switchover is to take place, an alarm is generated and the primary program is not dropped. For a custom backup program, the switch happens if at least one stream in the program is present.

Switching to a backup program may take up to 3 seconds.

Once a backup program is groomed instead of the primary program, the grooming continues as with any other program.

NOTE

Only one backup program can be selected for a primary program.

A single program or file can be defined as the backup for several primary programs.

The backup program (or elementary streams in the case of Custom Grooming) must be present at the DM input at the time when it is selected as a backup program.

The backup program may have a different number of elementary streams than the primary program.

Programs groomed to a PID Sharing Group cannot have backup programs.

The backup program cannot have any streams that are passed to the output.


A primary program is considered to have reappeared if all of the following conditions are satisfied:

- The primary program is listed in the PAT.- No alarms are generated for a defined time interval.

Grooming to a File

The DM Network CherryPicker supports grooming of an internal file to an Output Program. The video file stored on the Program Flash disk is groomed to the user-selected output, as if it were a standard video input. This file is usually a black video file with no audio. The following black video files are provided on the DM Network CherryPicker program flash disk in the directory /usr/cp/video.

ATSC black files are also provided in the /usr/cp/video directory.

Each of the ATSC black files have a 16:9 aspect ratio, 29.97 Hz frame rate, and interlaced progressive sequence. Each are IPP coded, progressive frames with the top field first.

You can use any valid MPEG video file (for example, a station logo used during an intermission) stored on the DM Network CherryPicker program flash disk in the directory /usr/cp/video. The name of the video file must have only alphanumeric characters and must not contain spaces. Audio is not groomed when using the Groom to Black feature

Grooming to Black

When Groom to Black is selected in the Grooming window, the video file selected from the Groom to Black pull-down menu is output from the DM Network CherryPicker until another groom command is sent. Which file is played can be auto-detected per stream or defined globally in the cp-controller.properties file. Refer to “Grooming to Black” on page 4-24.

black_720.ntsc black_720.pal






black_1920x1080

black_1440x1080

black_1280x720

black_640x480


If you leave the black file set to the default file "black", the video size of the groomed stream is automatically detected and a black file of the same video size is played.

To add a video file to the output multiplex using Groom by Schedule or Groom by Program:

1. Select New.

2. Select the Input/Output tab.

3. Select File.

4. From the File menu, select the name of the video file to groom.

Figure 6-23 Program Interval - Input/Output Tab - File

5. Click OK.

PID Sharing Groups

A PID Sharing Group allows you to include the same stream in multiple output programs and only use the bandwidth you would use when sending the stream once.

This has a couple of applications. First, if you have an input multiplex that already uses shared PIDs, you can create a PID Sharing Group to maintain the shared PIDs on the output. Second, if you have a video stream that needs to be output in multiple programs

NOTE

In PAL territories, use the default file name "black" (rather than black.pal) to allow automatic detection.


containing different audio/data stream combinations, you can save bandwidth by sending the video stream once and adding audio/data streams as needed.

For example, an input program "News" contains video with English audio, Spanish audio and data. We want to create three output programs:.

- Video, English Audio- Video, English Audio, Data- Video, Spanish Audio

Rather than using the bandwidth to send the video stream in three separate output programs, we can use a PID Sharing Group to send the video once, but still end up with three output programs.

The chart below shows a PID Sharing Group that is comprised of the elementary streams that are part of input service number 40 (PID 16, 17, 18 and 19). The three output programs created from this PID Sharing Group are PID 41, 42 and 43.

Creating a PID Sharing Group

Creating a PID Sharing Group, has four main steps:

• Name the PID Sharing Group• Add the new output programs• Add the elementary streams• Select which elementary streams are included in each new output program

Input (40) "News" Video (16) English Audio (17)

Chapter 7

Ad Insertion/DPI

DM N

Ad Insertion/DPI Overview

Figure 7-1 Typical Ad Insertion Architecture

The three critical parts of any digital program insertion (DPI) solution are the programming feed, an ad server, and a splicer. The DM Network CherryPicker acts as the splicer in a DPI solution and is fully-compliant with SCTE 30 and SCTE 35 standards. With the DM Network CherryPicker, an operator can seamlessly splice from the main video stream (programming feed) to a digital ad played by an ad server. When the ad ends, the DM Network CherryPicker seamlessly splices back to the programming feed.


What is Seamless Splicing?

Seamless splicing puts two streams together end-to-end in a way that a decoder can handle without glitches, missed frames or picture breakup.

In analog video distribution systems, switching between streams is done via an analog switch with the simple push of a button. In digital video distribution systems, switching between streams is more difficult. When a decoder is reading an MPEG stream with an ad insertion that was not properly spliced and the stream changes suddenly (when the ad is encountered), the decoder often reacts poorly; typically causing the output to freeze momentarily, display green, or break up completely. This makes the way the splicer handles the splice critical to the process.

The DM Network CherryPicker evaluates where ideal splices can occur in the MPEG stream prior to splicing. By splicing at the right point in the stream, the DM Network CherryPicker creates a seamless splice.

Analog Cue Tones

In the past, analog Dual-Tone Multi Frequency (DTMF) cue tones were used to indicate when ads would play. When this technology was in its infancy, it was common for viewers to hear these tones while they were watching programming. Today, programming is distributed via MPEG transport streams rather than analog waveforms and "cue tones" are embedded digitally, and silently, into the program stream. Server/splicers decode digital cues to determine when to play an ad. Typically, the splicer and ad server use intranetwork communication to communicate the results of the cue message decoding.

Digital Cue Tones - SCTE 30/35 DPI Communication Protocol

SCTE 30 messages are communications between the ad server and splicer that negotiate the initiation and completion of splicing between main network feeds and ads played by the ad server. The cue that notifies of an upcoming splice is not read by the ad server. However, the splicer reads the in-band SCTE 35 message and sends the cue request via SCTE 30 to the ad server. From this point, the splicer acts as an agent for the ad server and splices at the time specified through more SCTE 30 commands given by the ad server. The DM Network CherryPicker facilitates connection to the ad server and notifies the user of an impending splice through messages in the grooming window of the DM Network CherryPicker GUI.

Network Time

A critical element of DPI is the synchronizing of each device within the DPI subsystem. Without the careful management of event timing, splicing will not occur. Some ad servers carry a time server or network time protocol (NTP) server on their platforms, while others use third party NTP servers for timing reference. Regardless of the configuration, the ad server and splicer must use the same NTP reference to conduct


successful splices. The NTP server can be located anywhere on the network. In many deployed architectures, the DM Network CherryPicker uses the ad server itself as an NTP server.

Implementing Ad Insertion

Equipment Setup

DM Network CherryPicker hardware setup is the same for all standards-based ad servers. The DM Network CherryPicker can accept ads served via either DVB-ASI or Gigabit Ethernet input modules.

Port Naming

The hardware connection to the splicer must match the connections being referred to in the SCTE 30 messages. The port numbers designated for the ad server feed and the DM Network CherryPicker must correlate.

The DM Network CherryPicker uses an alphanumeric designation for its ports, while the SCTE 30 specification uses numbers. The ports map directly, A=1, B=2, C=3 and so on as listed in the table below.

For example: an ad feed that plays to the D1 port of a DM Network CherryPicker is referred to as: Chassis 1, Card 4, Port 1.

NOTE

A Terayon Ad Insertion software license must be installed on the DM Network CherryPicker for each channel where splicing will be done.

DM Port SCTE 30 Port DM Port SCTE 30 Port A1 Card 1, Port 1 D1 Card 4, Port 1

A2 Card 1, Port 2 D2 Card 4, Port 2



B1 Card 2, Port 1 E1 Card 5, Port 1




C1 Card 3, Port 1

C2 Card 3, Port 2


Splicer Naming

When connecting to the splicer, the ad server sends out SCTE 30 messages over the TCP/IP network. The designated splicer receives the messages and responds, attempting to open the connection. Since there may be several splicers on a network, the correct designation of the splicer is important.

The actual splicer name must match the name requested by the ad server. In Figure 7-2, the splicer name is "CherryPicker Manager".

Figure 7-2 Splicer Name

Incorrect Splicer Naming

In the next example, the name “EVS Splice” is being called, but the DM Network CherryPicker is actually named “CherryPicker Manager” as shown in Figure 7-2.

C3 Card 3, Port 3

C4 Card 3, Port 4


Figure 7-3 shows the error that displays when the splicer names are not correctly matched.

Figure 7-3 Splicer Naming Not Matched

The splicer must be renamed on either the ad server or the DM Network CherryPicker so that they match for ad insertion to be successful.

Channel Naming

The DM Network CherryPicker can be connected to many ad servers simultaneously. To manage the output, the ad server specifies a unique channel to splice to via SCTE 30 messages. In Figure 7-4, the channel is named "Channel 1".

Figure 7-4 Channel Naming


Incorrect Channel Naming

If the specified output channel does not match the available output channels, the DM Network CherryPicker displays an alarm and a new channel name is requested by the ad server as shown in Figure 7-5.

Figure 7-5 Channel Names Not Matched

In this case, the specified output channels should be renamed “Channel 1” in order to be controlled/spliced and served by the requesting ad server. Other ad servers can do the same so that each requests a unique DM Network CherryPicker output channel.

NOTE

Correct naming and naming convention is dictated by the server vendor. So, coordinate the naming of the channels with the server vendor.


Assigning an NTP Server

The NTP server can be located anywhere on the network. In many implementations, the DM Network CherryPicker uses the ad server itself as an NTP server.

To synchronize the DM Network CherryPicker with an NTP server, enter the server’s IP address in the NTP Server Address window as shown in Figure 7-6.

Figure 7-6 Entering the NTP Server IP Address

Verifying Access to the NTP Server

To verify the DM Network CherryPicker has access to ping the NTP server:

1. Telnet to the DM Network CherryPicker. For instructions, refer to “Connecting to the DM Network CherryPicker using Telnet” on page 10-3

2. Ping the desired NTP/SNTP server from the telnet prompt.

NOTE

If a third party NTP or SNTP server intranet or extranet is to be used, it is critical that the DM Network CherryPicker have ping access to this server.


Verifying Synchronization

To verify the quality of the synchronization:

At the command prompt, enter: ntpq –p 192.168.0.12

where 192.168.0.12 is the NTP server.

CherryPicker# ntpq -p 192.168.0.12 remote refid st t when poll reach delay offset jitter==============================================================================*63.201.251.37 164.67.62.194 2 u 61 64 377 1.100 -0.184 0.180

If the offset number is over ±10 milliseconds, a forced synchronization with the server is required.

An * next to the server IP address signifies the DM Network CherryPicker is properly synchronized and locked to the ntp server.

Forcing Synchronization

To force synchronization:

1. Telnet to the DM Network CherryPicker. For instructions, refer to “Connecting to the DM Network CherryPicker using Telnet” on page 10-3.

2. At the command prompt, type: PS AUX and press Enter.

3. Find the PID for the NTPD process.

4. Type: Kill -2 <PID for NTPD process> and press Enter.

5. Type: ntpdate -b <IP address of ntp server> and press Enter.

6. Type: ntpdate -d <IP address of same ntp server> and press Enter to verify the offset has been corrected.

7. Start NTPD by typing: ntpd -f /data/ntp.drift -A -g -N high and press Enter.


Successful Server/Splicer Connection

Successful connection by the server to the DM Network CherryPicker is visible in the DM Network CherryPicker GUI.

Figure 7-7 Successful Connection with Ad Server

“Ad server connected” displays next to all of the appropriate channels and "Ad Feed" displays next to the appropriate port.


Notification of Impending Splice

The DM Network CherryPicker facilitates connection to the ad server and notifies the user of an impending splice through messages in the Grooming Setup window of the DM Network CherryPicker GUI as shown in Figure 7-8.

Figure 7-8 Impending Splice Display

In this example, an ad insertion will occur at 5:40:00pm and end at 5:40:30pm.

States, Events and Alarms

DM N

This chapter discusses:

• states, events and alarms• viewing system events• setting system event options• filtering system events• clearing alarms

States, Events and Alarms

DM Network CherryPicker fault management has three levels.

State

A state is a set of instantaneous values of all the variables in the system, a snapshot of the system. For example, the state of memory may be characterized by its fullness (how many bytes are used). Other states may include the times when the last read and write operations occurred.

Event

An event is a transition of the system from one state to another. For example, a memory write is an event, which causes at least two system variables to change, the fullness and the last write time. Graphically, the relationship between states and events is shown in Figure 9-1.

Figure 9-1 States and Events

EventState 1

X=a, Y=b, Z=cState 2

X=d, Y=e, Z=c


Events are classified as normal or error events. An event is normal until it exceeds a defined threshold. When it passes this threshold, the event becomes an error.

Alarms

An alarm is an error report generated when a state transition takes place.

Alarms can be in two states: Raised or Fallen.

An alarm is raised when a value crosses a defined threshold. An alarm is fallen when the variable returns to its normal range, either by itself or due to an action by the operator.

Figure 9-2 Alarm States

While many errors might be reported while a variable is in a normal and then an error state, only two alarms are generated; one raised alarm and one fallen alarm.

Viewing System Events

The List screen displays information about events that the DM Network CherryPicker produces; such as grooming events, configuration changes, schedule changes, errors and alarms.

To sort events:

1. In the List window, select an Event that contains the parameter to sort (for example, severity or date).

2. With the event selected, click the top line of the column containing the parameter you are sorting.

For example, select an event with Severity level 4 and then click the Severity column heading. The list is sorted by error severity level.

4 Critical System is unable to continue functioning (failure of output module, loss of time reference signal at output, etc.)

3 Major Major functionality has failed (one of the two I/O modules failed or ad insertion is down while other functions are OK).

2 Minor Minor area of functionality may produce intermittent errors. (number of spliced frames in ad insertion is not equal to requested number).

1 Warning Error detected, whose origin is outside DM Network CherryPicker, is approaching a critical limit (input stream not meeting repetition rate requirement of an SI table or error bit is set in transport stream packet). The end device (set-top box) may be insensitive to this error, so normal operation of the DM Network CherryPicker continues.


Filtering System Events

The List screen displays all messages captured by the Network CherryPicker Desktop software.

2. Set the Maximum number of Normal Events, Error Events and Alarm Events.

Changing Default Error Severities

The DM Network CherryPicker allows you to change the error severity associated with a specific error code. For example, if you have an noisy input feed, you could change the error severity to 1 (Warning) so that it is not constantly triggering an alarm. Conversely, you could set the default severity of a normal event, such as grooming, to 4 (Critical) in case you want to trigger an alarm when grooming occurs.

NOTE

The system maximum for stored events is 1000 (raised and cleared) of each type (events, errors and alarms).


To change default error severities:

1. From the Options screen, select the Severity of the event that requires a change.

Figure 9-7 Event Severity

2. Change the Severity to the desired value.

3. Click Apply.

4. To set the new error severity levels as the new default, click Default.

Alarms

Alarm events cause the front panel LED on the DM Network CherryPicker to glow red alerting you to situations that may, or may not, require your attention.

Viewing Alarms

To access the alarms screen:

1. From the DM Network CherryPicker Desktop menu, click the List button.

If an alarm is active:


1. On the lower right corner of the DM Network CherryPicker Desktop, double-click the red, flashing Alarm: On button.

Clearing an Alarm

Turn off the blinking red Alarm button by acknowledging the alarm(s).

To acknowledge an alarm:

1. From the List screen, select the Alarm(s) to acknowledge.

2. Click Clear Alarms.

When you acknowledge an alarm, the flashing red Alarm button returns to its normal Alarm: Off state and the red LED on the DM Network CherryPicker turns off.

NOTE

Alarm data is logged and stored on the data flash in the file \data\log\alarm.log.

NOTE

To ensure alarms are displayed, make sure that the Alarms box on the List screen has been checked.

NOTE

To remove cleared alarms from the list, in the Events List window, select the Hide Cleared Alarms button.

NOTE

Users must have Acknowledge Alarms selected in the Administrator permissions screen to acknowledge alarms.

Most Common Problems

Most problems encountered by Terayon Technical Support personnel involve source issues (encrypted programs, incorrect audio type, etc.), improper DM Network CherryPicker configuration, or set-top configuration/channel mapping issues.

Having a working knowledge of the devices and systems involved in the provision of digital services minimizes the occurrence of problems, as well as time to repair.

One of the best sources for troubleshooting information is the manual provided by the equipment’s manufacturer. This is probably the most under utilized tool at a technician’s disposal.

Some basic rules that apply to all digital system troubleshooting:

1. Look for any changes that have taken place since the system was last work-ing properly.

2. Verify that all cabling is installed and connected properly.


It is important to have an understanding of the functions of the various components and systems that make up a digital headend. Some areas to become familiar with include:

Satellite receiver, encoder, etc.

- operation and program authorization procedures/verification

Digital set-top controller system operation/requirements

- channel map/session configuration and required information- provisioning and operation of output devices. (i.e. QAMs, IRTs, MPS, etc.)- output configuration/parameters of the DM Network CherryPicker- specific requirements of the set-tops deployed in the system. (i.e. Motorola set-tops require

audio type to be AC-3)

Encryption (Conditional Access) system setup/requirements

- Check for changes in the program stream data or configuration from the source/provider.

Troubleshooting from the GUI

Useful troubleshooting information available from the DM Network CherryPicker Desktop GUI screens:

Input/Source Information

The Configuration and Stream/Program Analysis screens provide a great deal of information about the data coming into and going out of the DM Network CherryPicker.

Configuration and Program Analysis

• Input PMT, video, audio, and data PIDs• Video, audio, and data type• Encryption status of input programs

Stream/Program Analysis

• Bit rates for input programs and elementary streams• Output program and elementary stream bit rates as well as PIDs and video/audio

type (using a loopback cable from an output to an unused input port.)

Stream Analysis and Grooming Schedule/By Program

• Grooming verification and status


Connecting to the DM Network CherryPicker using Telnet

To Telnet to the DM Network CherryPicker:

1. From the Windows Desktop on a host PC, select Start >Run.

2. In the Run dialog box, type:telnet xxx.xxx.xxx.xxxwhere xxx.xxx.xxx.xxx is the IP Address of the DM Network CherryPicker.

3. Click OK.

4. Once connected, type root, then press Enter.

5. Enter your unique password. The default password is terayon.This logs you into the root directory.

Connecting to the DM Network CherryPicker using HyperTerminal

Since the DM Network CherryPicker serial port is configured to work with an external modem by default, use these steps to configure it as a serial console:

1. Connect a null modem cable from the host computer COM1 port to the DM Network CherryPicker.

2. From the Windows Desktop on a host PC, select Start >Run.

3. In the Run dialog box, type: hypertrm

4. Enter a name for the new connection.

5. In the Connect Using drop down list, select COM1, press OK.

6. Configure the settings as listed below, then press OK.

- Bits per second: 115200- Data bits: 8- Parity: None- Stop bits: 1- Flow control: None

7. Set the terminal type to VT100.

8. Leaving HyperTerminal in the Connected state, reboot the DM Network CherryPicker.

9. Press Esc during the 5 second countdown. (If you do not press Esc within the 5 seconds, the DM Network CherryPicker will boot with the default configuration, which will set the serial port to modem.)

10. Select Serial Console Configuration, press Enter.

11. At the DM prompt, login to the device.

12. You are now at the DM Network Cherrypicker Login screen.


Rebooting the System

Since the DM Network CherryPicker does not have a power on/off switch, disconnect the chassis from the power input, wait a few moments and then reconnect to reboot the hardware.

Changing the Root Linux Password

To change the root Linux password to access the DM Network CherryPicker:

1. Login as root.

2. At the command prompt, enter the command passwd.

3. Enter a new password.

4. Enter the new password again to confirm. A message, "all authentication tokens updated" will display.

Removing a Module

Modules are not hot swappable. To add or remove a module requires powering down the chassis.

1. Ground yourself using proper electrostatic discharge (ESD) protection such as an anti-static strap.

2. Power down the chassis.

3. Remove the screws that secure the module you wish to remove.

4. Use the ejector lever to release the bus connector from the backplane.

5. Grasp the front edge of the module and pull the card out slowly, guiding it straight out of the slot. Hold the module by the edges only. Do not touch the surface of the board or connector pins.

6. Place the module component-side up on an antistatic surface or in a static shielding bag.

Replacing the Data Flash

1. Power down the chassis.

2. Remove the compact data flash card from the slot.

3. Insert the new compact flash card into the slot until the card firmly seats in the connector at the back of the slot.


4. Power up the chassis.

Diagnostics Interface

The diagnostics interface is used for system troubleshooting. It can be used in the headend where a DM Network CherryPicker is installed or it can be used remotely by Terayon Technical Support. The diagnostics interface bypasses the GUI, front panel and any SNMP Manager and communicates directly with the operating system and application software. The DM Network CherryPicker allows for three physical connections for diagnostics:

• Ethernet• Serial Modem• Serial Console

The Ethernet connection is the most flexible; it allows both local and remote troubleshooting. Fire walls that may be present at your site, however, may restrict access to the network from outside. If that is the case, a modem connection is used connected to the serial port.

The serial port can also be used as a console using the default Linux configuration. Connected directly to another computer, a terminal emulation application such as HyperTerminal allows Terayon Technical Support to login and run diagnostics. This configuration is appropriate only for on-site troubleshooting. The key benefit of using the console port for diagnostics is that it is the only interface that allows system monitoring and interactions during an OS reboot.

Introduction

Configuration commands are powerful tools that allow the advanced user to customize the Network CherryPicker to a specific environment. Configuration commands are text commands that are entered into the text of the Configuration file. The Configuration file is then loaded, changing the behavior of the Network CherryPicker.

Configuration commands are applied globally to the entire output multiplex to which the Configuration file is loaded. It is important to note that when working with multiple output multiplexes, a separate Configuration file must be applied to each output. Also, since some of the configuration commands affect the names of the input feeds/multiplexes/programs, be advised that it is the last configuration file loaded that will affect the input names.

When a Configuration file is loaded, all programs previously groomed to the output multiplex are removed from the output multiplex.

Configuration commands are executed in the order they appear in the Configuration file. For most configuration commands, where they occur in the Configuration file is not important. For configuration commands that need to be entered above other commands, such information is included for your information.

Understanding PIDs, PESs, PMTs and PATs

Before working with a configuration file, it is important that you are familiar with some basic MPEG concepts. The following figure shows how the PAT, PMT and the PESs are related:

Program Number The Program Number (also known as MPEG Service Number) uniquely identifies each program.

Packet Identification (PID) Packet Identification (PID) numbers uniquely identify each component of a transport stream.

Components of a Transport Stream

Packetized Elementary Stream (PES) PES PIDs identify the video and audio elementary streams that combine to create a program. Synchronous data streams are also identified by PES PIDs. There is one PES PID for each elementary stream.

Program Map Table (PMT) PMTs identify the PESs (for each elementary stream) that belong to a program and their stream types. There is one PMT for each program.

Program Allocation Table (PAT) PATs identify the PMT (for each program) that belong to a transport stream. There is one PAT for each transport stream (multiplex). The PAT PID is always 0.

Elementary Stream Types The PMT lists the elementary streams that compose a program and identifies each elementary stream by its MPEG stream type. The following table lists the stream types most commonly used, although the MPEG specification allows these numbers to vary.

Configuration File Processing A configuration file is a text file that sets the parameters and behavior of the device.

Configuration commands are applied globally to the entire device to which the configuration file is applied.

The following general rules apply to all the commands:

• No spaces are allowed in the values for any field in the command.

• Any command other than those specified below is ignored.

• All commands are terminated by a carriage return (or Enter) keystroke. A single command can span several lines as long as there is no carriage return in the line.

• Any line that starts with a pound sign # is considered a comment and is ignored.

Command Syntax The syntax of each configuration command is:

COMMAND_NAME <mandatory_parameter> [<optional_parameter>] [KEYWORD] {<repeated_parameter>}

COMMAND_NAME Single word in upper case alphabetical characters and underscores only.



< > Parameter delimiter used in command definitions and not included in the actual command as written in the Configuration file.

<mandatory_parameter> One or more mandatory parameters that must be present in the command. If any of these parameters is not present, the entire command is ignored.

[<optional_parameter>] Optional parameters are enclosed in square brackets.

KEYWORD Keywords may be included in the command. If it is defined in a command definition, then it is a mandatory parameter for that command. Keywords must be typed in capital letters.

{<repeated_parameter>} One or a group of parameters that may be repeated with different values assigned to each parameter. For example, this could be a sequence of parameter pairs {stream type, PID} for elementary streams in a program. A group of repeated parameters is enclosed in curly brackets.

Naming Syntax User-defined names are written without spaces(name). If spaces are required in the name, use double quotes (“name of stream”).

Reserved PIDS Many PIDs are reserved by MPEG and ATSC standards. The assignment of reserved PIDs should follow the guidelines specified in the corresponding standards. We required that reserved PIDs not be assigned to arbitrary streams.

Examples of reserved PIDs include:

MPEG 0x0 to 0xf and 0x1fff ATSC 0x1ffb to 0x1ffd

Binary Tables In order to specify binary tables (which may contains non-printable characters) as a parameter in a configuration command, an ASCII encoding rule is used to make it printable/readable by the software. The ASCII encoding rule expands one binary byte, written in hexadecimal notation, into two printable characters where each character is either the corresponding letter or digit used in the hexadecimal notation. All letters must be written in lower case.

For example: one byte 0xFF is encoded as “ff” in ASCII one byte 0x80 is encoded as “80” in ASCII

Exception Handling If a syntax error is encountered when the configuration file is applied:

commands containing errors are skipped error-free commands are applied an alarm is generated



Commands

Buffer Management

These commands are used to customize the elementary stream buffer, main elementary buffer, system information main buffer and drain rate at which data are removed from the transport buffer to accommodate MPEG buffer sensitive decoders.

AUDIO_BUFFER_FULLNESS <audioBufferFullness>

Sets maximum audio elementary stream main buffer fullness.

Introduced in version 1.0.

Applying a Configuration file with a change to this parameter will cause the DM Network CherryPicker to restart affecting output services.

<audioBufferFullness> Default 0.9 (90%) / Min 0.3 / No Max

AUDIO_DRAIN_RATE <audioDrainRate> Sets drain rate Rx, the rate at which data are removed from the transport buffer.



<audioDrainRate> Default 2,000,000bps / Min 10bps / No Max

DATA_BUFFER_FULLNESS <systemDataBufferFullness>

Introduced in version 1.0. Obsolete in version 4.0.

Applying a Configuration file with a change to this parameter may cause disruption to the associated output multiplex.

<systemDataBufferFullness> Min 0.3 (30%) / No Max

DATA_DRAIN_RATE <systemDataDrainRate>



<systemDataDrainRate> Drain rate at which data are removed from TBsys in core software.

Default 300,000,000bps / Min 10bps / No Max



HDTV_VIDEO_BUFFER_FULLNESS <ratio>

Sets video EB fullness for HDTV high level, main profile.



<ratio> Default 0.9 (90% full) / Min 0.3 / No Max

HDTV_VIDEO_DRAIN_RATE <drain rate> Sets drain rate at which data are removed from TB of main profile/high level stream.



<drain rate> Default 96,000,000bps (19.4MB ATSC) / Min 10bps / No Max

TS_DRAIN_RATE <tsDrainRate>

The integer TBsys drain rate of the transport buffer for system information as defined in bps.



<tsDrainRate> Default 1,000,000bps / Min 10bps / No Max

VIDEO_BUFFER_FULLNESS <videoBufferFullness>

Sets video EB fullness.



<videoBufferFullness> Default 0.9 / Min 0.3 (software may not output data below this level) / No Max

VIDEO_DRAIN_RATE <videoDrainRate>

The drain rate at which video data are removed from TB buffer as defined in bps for main profile, main level video stream.





<videoDrainRate> Default 18,000,000bps / Min 10bps / No Max

Configuration Management

BANDWIDTH <outputLineID> <outputMuxID> <bandwidth>

Sets output line bandwidth.



<outputLineID> Output line ID.

<outputMuxID> Output multiplex ID.

<bandwidth> Bandwidth in bps (must be positive integer).

CAT <interval> <cat table>

Specifies output CAT and how frequently it is sent.


<interval> Default 9000ms / Min 16ms / Max 10,000ms

<cat table> CAT encoded in ASCII format. In most cases, this command is not used since the CAT is generally inserted downstream from the Network CherryPicker.

CLEAR_RESOLUTION <inputLine Name/ID> <inputMux Name/ID> <inputProgram name/ID> <inputStreamPID> <type>

This command ends the resolution change operation for the selected stream and frees the resolution change hardware resource used for this stream. Note that strictly speaking, this command is not needed; the absence of the command SET_RESOLUTION from a configuration file will have the same effect. This command is introduced for possible use via SNMP.


<inputLine Name/ID> Name or ID of the input line (port) with the stream whose resolution will be changed.

<inputMux Name/ID> Name or ID of the input multiplex in the input line with the stream whose resolution will be changed.

<inputProgram name/ID> Name or ID of the program in the input multiplex with the stream whose resolution will be changed. Setting <inputProgram name/ID> to “–1” indicates that resolution change applies to a specific PID rather than to a program.



<inputStreamPID> PID in the input multiplex of the stream whose resolution will be changed. Setting <inputStreamPID> to “–1” indicates that resolution change applies to a program rather than to a PID.

<type> Must be “1”. Reserved for future use.

CUSTOM_GROOM <number of PIDs> {<input line name/ID> <input mux Name/ID> <input program name/ID> <input stream PID>} <output line name/ID> <output mux name/ID> <output program name/ID> <priority> <min bit rate> <max bit rate> <do not recode> [BACKUP_PROGRAM <backup input line name/ID> <backup input mux name/ID> <backup input program name/ID> <any or all> <alarm interval> <number of alarms> <back to primary> <error-free period>] [BACKUP_STREAMS <number of PIDs> {<backup input line name/ID> <backup input mux Name/ID> <backup input program name/ID> <backup input stream PID>} <any or all> <alarm interval> <number of alarms> <back to primary> <error-free period>] [BACKUP_FILE <backup file name> <any or all> <alarm interval> <number of alarms> <back to primary> <error-free period>]

Used to custom groom streams to output multiplex. The parameters in {} are repeated for each input stream PID.

Introduced in version 1.0. Keywords BACKUP_PROGRAM, BACKUP_STREAMS, and BACKUP_FILE added in version 4.0.

CUSTOM_GROOM command must be placed in the Configuration file after the PMT and other commands that specify the parameters used in this commands, such as various names and the output program number.

Only one of the keywords BACKUP_PROGRAM, BACKUP_STREAMS, and BACKUP_FILE can be included in a single CUSTOM_GROOM command.

<number of PIDs> Total number of input stream PIDs for this grooming.

CherryPruning CherryPruning is a special case of rate shaping where only the maximum bit rate of any particular service is specified. This can be very useful in xDSL or fixed bandwidth environments. CherryPruning takes either the SPTS or MPTS and breaks it apart into separate SPTS streams. This limits individual program bandwidths to a lower output bit rate than the input bit rate. These programs are then formatted into CBR output (preventing further rate shaping, which may affect the signal quality).

Compression Coding data using fewer bits than the original code, thus saving space and transmission time.

Configuration Tree An expandable outline listing the entire CherryPicker system controlled by a DM Network CherryPicker (Sites, input feeds, input multiplexes, input programs, output feeds, output programs).

Priority A priority number determines output program bandwidth priority in cases where grooming demands recoding. The higher the number (in a range from 0-10), the higher the program priority and the less the chance that it will be recoded. An output program with a priority of 10 is never recoded and always retains its configured bandwidth. Lower priority programs may be recoded to reduce their bandwidth requirements when the output transport stream is fully utilized.
