Audio and video over IP technology

Due to the pocket structure of IP (Internet Protocol) infrastructure, it was difficult to use it in Broadcast applications where high bandwidth for large amount of data is needed. Greater chance of IP pocket loss compared to SDI signal failure and latency were biggest challenges for engineers to design equipment that will use IP infrastructure for transport and processing of Audio and Video content with ancillary data. With adopted SMPTE 2022 and 2059 series of standards, equipment manufacturers get the base to develop equipment that will use IP infrastructure even for the most critical live Broadcast applications. This paper shows details of SMPTE 2022 series of standards that is important for high performance video traffic over IP networks and recently adopted SMPTE 2059 standards that are solving the synchronisation problem and integration with existing SDI-based systems. When synchronisation problem has been solved, it was much easier to implement features like clean video switching over IP.
