The Video Services Forum (VSF) has released two new ancillary features to enhance the Reliable Internet Streaming Transport (RIST) protocol by incorporating Decoder Synchronisation and Multicast Discovery.
Detailed in TR-06-4 Part 4, the Decoder Synchronisation, the fourth in a series of ancillary features for RIST specifications, provides a way to synchronise the decoder playback when multiple encoders are transmitting signals to multiple decoders over IP for applications such as live sport, said the VSF.
TR-06-4 Part 4 provides a common specification to synchronise multiple cameras in use at a remote location, supporting an arbitrary number of encoders and decoders.
Multicast Delivery, detailed in TR-06-4 Part 5, provides a simplified way to manage multicast traffic over RIST tunnels, avoiding unnecessarily sending streams to receivers not interested in them, thus saving bandwidth, said the VSF.
Ciro Noronha, president of the RIST Forum, said: “The number of RIST-enabled solutions on the market continues to increase. With these latest releases covering decoder synchronisation and multicast discovery, RIST can now be implemented into many more products covering each part of the contribution and distribution workflow.”
The RIST protocol is designed to reliably transport video over unmanaged networks such as the internet, providing an open, interoperable, and technically robust solution for low latency video contribution.
