6. AQORD main functions 6.1. Encoding / Decoding

The output can be IP and HDD at the same time.

6.2. Full duplex AQORD *LINK 2C Only

6.3. Streaming / Recording AQORD *LINK products only.

The “streaming” function allows to stream a MPEG­TS video file stored on the Hard Disk Drive over UDP/RTP. The “recording” function allows to store on the Hard Disk Drive as a MPEG­TS video file the received IP stream UDP/RTP.

6.4. Dual Streaming Mission critical video transport One objective of broadcasters while deploying their IP infrastructure is to achieve the robustness of synchronous telecom or satellite networks on private leased lines while reducing significantly the corresponding production costs. The experience gained from existing IP infrastructures proved that IP network disturbances are of a different nature when occurring inside the Telco backbone infrastructure or during the “Last Mile” path (i.e. near/inside the broadcasters premises). So it is essential for the broadcaster to choose an appropriate operation strategy for each different type of transport he will use, such as fully managed networks using QoS or “Best effort” networks (Internet, Wireless 3G/4G and Wifi).

AQORD encoders/decoders implement FEC (Forward Error Correction) and now “Dual Streaming” to secure the transmission in order to meet Broadcasters and Telcos IP transport strategies.

At the source side, AQORD sends and carries the same Video IP stream on two distinct networks. Then on the receiver side, it automatically synchronizes both received streams. The different IP paths followed on each network ensures that the potential failures are statistically uncorrelated, enabling the reconstruction of an unique unperturbed stream.

Figure 8: “Dual Streaming” contribution Benefits from AQORD permanent redundancy or “dual streaming” : Allows you to make use of an economical network despite low QoS. Limitations : Obviously one needs two different and independent network links between encoder and decoder. The decoder sets the size of its receiving buffer based on a set of measurements to take into account the delay between the two links and the jitter of each of them, in order to minimize the size of this buffer and thereby minimize the overall system latency. “Dual Streaming” can be combined with FEC in order to increase transmission robustness.

It allows quick access to various settings of the machine:

Profile administration: “Profile”. User hard disk space and video files: “Storage”. System parameters: “System”.

9.2. “System administration” pages

9.2.1. “Shutdown/restart” This page allows you to restart or shutdown the AQORD. Re­starting AQORD is required when changing network settings (see chapter “Network settings”).

9.2.2. “Usage statistics” This page displayed some statistic information like: Number of started profiles, lost packets, recovery packets, late packets and so one. This page is mainly intended to give you some measurement information that help understanding the quality of your contribution link. Below are the available information for each contribution profile (mainly information from decoding profile):

"Received Packets": Number of received packets "Lost packets": Number of lost packets:

required RTP network protocol (UDP protocol doesn’t allow to know lost packets) If FEC is active. “Lost packets” means number of packets that could not be recovered by FEC

algorithm "Reordered Packets" : Number of disorder packet received

required RTP network protocol (UDP protocol doesn’t allow to know packet order) "Recovered Packets" : Means number of packets recovered by FEC algorithm. "Input Bitrate" : input stream bitrate received by a decoding profile. "Duplicated Packets" : Duplicate packets received. When “dual link” capability is used (link redundancy)

pourcentage should be 100% if not packets is lost. "Duplicated Packets Delay" : Max Delay between the two links when “dual link” capability is used. "RESET" button: reset all the counters above. "Output Bitrate" : output stream bitrate sent by a encoding profile.

Global parameters:

"ETHx Input Bitrate" : IP bitrate received on Ethernet interface ETHx "ETHx Output Bitrate" : IP bitrate sent on Ethernet interface ETHx

9.2.3. “Machine Name” An arbitrary name can be assigned to the AQORD. This name then appears in the Internet browser tab and in the banner at the top of the page.

14. Forward Error Correction 14.1. Introduction Unfortunately, real networks are not perfect and packet losses occur. In order to cope with packet losses, the AQORD has implemented Pro­MPEG FEC according to Pro­MPEG Code of Practice #3 rev. 2. Pro­MPEG FEC is carried out on RTP packets. The mechanism is based on the insertion of additional data containing the result of an XOR (exclusive OR)­operation of packets over a time window. The generation of FEC packets is based on the use of a matrix. The matrix size is defined by the number of columns (L) and the number of rows (D). By iterative operations it is possible to correct more than one missing packet per column or row. Please note that 4 ≤ L ≤ 32, 4 ≤ D ≤ 32 and L+D ≤ 32 and that the maximum matrix size is 256(L*D). When using column FEC only, L is allowed to be in the range 1 ≤ L ≤ 32. The size of the matrix is a trade between latency, transmission overhead and error protection. Column FEC provides correction for consecutive burst packets loss of up to L packets. The FEC packets are generated per a column within the matrix allowing loss of any single media packet within a column or a burst of packets of errors within a row to be corrected through the FEC packet.Column FEC is used to correct burst errors and random errors.

Row FEC provides correction of non­consecutive packet loss and can correct any single packet loss within a row of media packets. The FEC packets are generated per a row allowing loss of any single packet to be recovered. Row FEC is ideal for correcting random packet errors. Once the FEC packets have been computed they are transmitted with the media packets to the receiver site. FEC column packets are transmitted on UDP port n+2 and FEC row packets are transmitted on UDP port n+4 where n is the UDP port of the media data. This is in accordance with Pro­MPEG CoP 3.

14.2. How to monitor packets lost and packets recovered To monitor packets lost, packets recovered and more, refer to chapter “Usage statistics”

14.3. Configuration examples To know the link quality (delay, lost packet, received bitrate), refer to chapter “Usage statistics”. These statistics will help you to choose the right FEC matrix configuration.

Robust configuration

FEC mode : Column and row

Number of columns : 6 Number of rows : 4

Overhead due to FEC redundant

packets: about 40%

Default configuration for IP contribution network

FEC mode : Column and row Number of columns : 10 Number of rows : 10

Overhead due to FEC redundant

packets: about 20%

Configuration to reduce overhead

FEC mode : Column only Number of columns : 10 Number of rows : 10

Overhead due to FEC redundant

packets: about 10%

16. Typical applications The AQORD can address different markets like Broadcast and IPTV. This section presents some typical applications for these markets like:

Full Duplex video transfert for conferencing, training, meeting for corporate or academic applications. Point to point contribution to transmit high video quality over long distances through IP network. Live Event Contribution to Studio for video processing. Contribution using Octoshape Infinite HD technology. IPTV video distribution on Local Area Network for SetTopBox or computer player.

For more information on how to configure AQORD for point to point application, request to Digigram support the guideline document : “Point to Point Contribution Application Installation guide“

16.1. Typical IP internet contribution

16.2. Typical IP satellite contribution

16.3. Dual Streaming For the contribution range AQORD encoder/decoder : the new dual streaming feature help to secure video transport between two locations (ex: from event field to the studio). Dual streaming is for point to point contribution market (AQORD). This schematic shows IP Satellite + Internet link dual streaming redundancy. In that case the AQORD encoder (location 1) pushes the stream to the two different links then the AQORD decoder (location 2) will sort the received packets (received in double). If one of the links transmission is interrupted, the contribution will continue on the second one.

16.4. Duplex application : academic application example AQORD *LINK 2C product has full duplex capability. It has two completely independant channels. Each channel can be configured as an encoder or a decoder. This flexibility allows to stream two different contents between two locations in the same or opposite directions.

16.5. Point to multi­points contribution application example AQORD can manage several IP protocols like: UDP, RTP, RTP with FEC, Unicast and Multicast. The schematics below shows multi­unicast capability to address different locations with different destination public IP addresses.

16.6. Octoshape Point to multi­points contribution application example AQORD embeds Octoshape (Akamai) Broadcaster that allows to benefit to Octoshape specific protocol. See more details on Octoshape Technology here. The schematics below shows a point to multi­points contribution through Octoshape Servers. The AQORD pushes only one stream to Octoshape server and several AQORD can request the stream for decoding purpose.

17. Glossary

Term Description CBR “Constant Bit Rate“: The encoding is done at a constant rate very close to the value of

"Video Rate" defined. BALANCED AUDIO Audio numeric interface. Connector used: XLR ETHERNET RJ45 connectors:

\ 10 Base­T : 10 Mb/s \ 100 Base­T : 100 Mb/s \ 1000 Base­T : 1000 Mb/s (Gigabit Ethernet)

GOP Groups of Pictures, which consist of keyframes and delta frames. FEC The Pro­MPEG CoP #3 FEC scheme uses the RTP transport protocol as a building block

for providing packet recovery techniques to ensure reliable real­time media transport. FIREFOX Web browser: http://www.firefox.com CHROME Web browser: https://www.google.com/chrome/ H.264/AVC H264 is a standard codec for video encoding. H264 allows two times more compression

than MPEG2 for the same image quality. HD High definition video HDD Hard Disk Drive MPEG Motion Picture Expert Group MPEG2 MPEG2 is a standard codec for video encoding MPEG2­TS MPEG2 Transport Stream. Do not be confused with the MPEG2 Codec. PID An MPEG2­TS is composed of video stream, audio stream, subtitles etc... Each of these

packages is composed of an elementary packet stream stamped with a unique identification number, or Packet IDentifier (PID)

PCR Program Clock Reference. In order for the decoder to synchronize to the correct decoding speed of the TS packet a PCR Packet is periodically inserted.

PMT Program Mapping Table. Identifies and shows different PID for each program contained in the MPEG2 TS stream.

SD Standard definition video SDI “Serial Digital Interface”, raw video interface using BNC 75 Ohms cable. Bit rate of 270

Mbits/s for SD video, 1.5Gbits/s for HD video (1080i) STREAMING The "streaming" function allows AQORD *LINK to send or receive video in real time over

the Ethernet network. During transmission the video is sent from the hard disk. During reception the video is stored on the hard disk.

Ta Ambient temperature TTL Time to live (TTL) is a mechanism that limits the lifetime of IP packet in a network. TTL is

implemented as a counter attached to IP packet and the value is reduced by every router on the route to its destination. Once the TTL value in a packet goes down to “0”, IP packet is discarded. In computer networking, TTL prevents a data packet from circulating indefinitely.

USB “Universal Serial Bus”. Standard of connection between a computer and its peripherals. VBR “Variable Bit Rate”: The encoding is done at a rate that varies depending on the video

content. The bit rate is maintained equal to or below the "Video Rate" defined.
