Chapter 1: Overview - Xilinx SMPTE 2022-5/6 Product Manual

Overview
As broadcast and communications markets converge, and the use of IP networks for
transport of video streams becomes more attractive to broadcasters and
telecommunication companies alike, the adoption of 10 Gb/s Ethernet for the transmission
of multiple uncompressed Serial Digital Interface (SDI) streams is becoming a major
customer requirement. The industry is primarily looking at the SMPTE 2022 set of standards
to create an open and interoperable way of connecting video over 10GbE equipment
together and ensuring that Quality of Service (QoS) is high and packet loss is kept to a
minimum or recovered through FEC. As shown in
is aimed at contribution networks (for example, between broadcast center and regional
studio).

The core includes Forward Error Correction (FEC). FEC protects the video stream during
transport of high-quality video over IP networks. With FEC, the transmitter adds
systematically generated redundant data to its video. This carefully designed redundancy
allows the receiver to detect and correct a limited number of packet errors occurring
anywhere in the video without the need to ask the transmitter for additional video data.
These errors, in the form of lost video packets, can be caused by many reasons, from
thermal noise to storage system defects and transmission noise introduced by the
environment. FEC gives the receiver the ability to correct these errors without needing a
reverse channel to request retransmission of data. In real time systems, the latency is too
great to request a retransmission. The ability of Xilinx FPGAs to bridge the broadcast and
the communications industries by performing highly integrated real-time video interfaces
help broadcasters reduce costs as well as reduce the overall time it takes to acquire, edit
and produce content. Now that video can be reliably delivered over 10 Gb/s Ethernet
(10GbE), broadcasters can replace some of the expensive mobile infrastructures supporting
