IMPLEMENTATION REALITIES OF SMPTE 2110 AND PTP
At WGBH-TV

This presentation will be a tutorial on the what you need to know to understand the challenges we face in the process of making the transition to IP based transport for video, audio and data.

This move toward infrastructure efficiency has brought new technical challenges requiring broadcast engineers to gain an understanding of the technology and the new techniques needed to monitor these signals.

The development of SMPTE ST 2110 is a suite of standards that provide encapsulation of uncompressed video within IP packets and for live IP production carrying separate streams of video, audio and data packets. This new standard also allows for SMPTE ST 2022-6 that provides encapsulation of uncompressed SDI as well as ST 2059 for system timing.

This presentation we will take a look at the basic structure of the packets for ST 2022 and ST 2110 and how variable delay across the network introduces jitter at the receiver and how measurements can be made on the stream. Latency in the network can produce out of order packets or corruption of the data causing packets to be dropped. Therefore it is important to monitor the stream to ensure an error free network to ensure transmission of the High Bit Rate Media and how these errors affect the actual video and audio signal. For redundancy in the media network SMPTE ST 2022-7 can be used to provide a Path One and a Path Two stream that the downstream device can determine which path is the most appropriate to use. Measurement of the integrity of both paths is important and we will look at ways of monitoring the signal paths.
