Open Broadcast Systems has stated that its range of IP encoders and decoders now support the new Reliable Internet Stream Transport (RIST) protocol, for interoperable low latency contribution quality video via unmanaged networks, including the internet.

RIST is based on the Video Services Forum’s TR-06-1 technical recommendation document and the collaboration of all leading vendors and global broadcast operators.

Kieran Kunhya, MD at Open Broadcast Systems, commented: “RIST gives us a simple yet highly effective method for interchanging professional signals between different vendors. It’s a natural evolution of existing multivendor techniques (instead of starting from scratch with a much more complex solution like some propose).

“We have aligned our existing retransmission product to comply with RIST as it is much simpler than alternatives. For this reason, we believe RIST will have wide adoption in the professional broadcast world.”

Said Kunhya on why RIST is important generally: “It allows professional broadcasters to share IP video over unmanaged networks in a multivendor fashion.”

He added that for sports broadcasters, the future will be simpler with RIST. He explained: “There’s lots of vendor-specific unmanaged IP transport going on in sports broadcasting; RIST will let them do that in an industry standard fashion. Different broadcasters with different equipment can share feeds over unmanaged networks safely.”

Meanwhile, Adi Rozenberg, VideoFlow’s co-founder and CTO is an active participant of the RIST Workgroup. He added: “RIST is leveraging technologies and standards already in use by the professional broadcast industry to provide the level of reliability and video quality expected by professionals. I am happy to see that Open Broadcast Systems selected RIST for its contribution over IP solutions. I am sure that other vendors will follow Open Broadcast Systems decision to integrate RIST for video delivery over IP.”

Being developed by members of the Video Services Forum RIST workgroup goal is to lay the foundation for a standard that vendors can implement in their products. The TR enables different vendors to communicate and transfer live content over any IP network including the Internet.

Open Broadcast Systems provides a range of software-based encoders and decoders, which deliver high quality video over IP. It provides broadcast software for video and audio transport, running on off-the-shelf IT equipment. This allows IT hardware to perform multiple broadcast functions, aiding convergence between the broadcast and IT industries, and drastically reducing costs.
