RIST Protocol: Continually Improving

In the 5 years since the Reliable Internet Stream Transport Activity Group (RIST-AG) was formed, it has worked to continually improve the RIST protocol. In that time, it has produced three major Specifications, each designed to meet differing requirements with regard to transporting video over the Internet: RIST Simple Profile (TR-06-1), RIST Main Profile (TR-06-2), and RIST Advanced Profile (TR-06-3).  

The RIST protocol is typically used for professional media workflows with use cases such as news and sports contribution, remote production, affiliate distribution and primary distribution.  

It’s important to continually refine and improve ways of working in any industry, and that becomes even more critical in an industry as fast moving as broadcast and media. This is why the RIST AG constantly works to develop additional RIST specifications and features.  

New ancillary features

The RIST AG is currently working on several ancillary features to RIST, which will come out as TR-06-4 Parts. The first Part is already out and specifies Source Adaptation, providing protocol support for dynamically changing the stream source in response to changes in network conditions. This update introduced a feature to further improve packet loss recovery, enabling video providers to contribute content over the public internet even more seamlessly than before. 

Further ancillary features currently being developed include synchronized decoding, VPN use, a relay service, and control.
