The broadcast industry is in the process of transitioning n to IP based transport for video, audio, and data. This has led to the development of standards including SMPTE ST 2022-6 that provide encapsulation of uncompressed SDI within IP packets and the SMPTE ST 2110 suite of standards for Professional Media Over Managed IP Networks.
These standards provide the interconnection framework for an all-IP infrastructure within a facility. The way in which these data packets flow across the network requires a variety of protocols to send this information bi-directionally from the source to the destination. Requiring broadcast engineers to gain an understanding of the technology and the new techniques needed to monitor these signals.
In this webcast, we will examine the basic structure of the packets for ST 2022-6 and the ST 2110 suite 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 critical to monitor the stream to ensure an eerror-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.
