The Video Services Forum (VSF) has released the latest ancillary feature to enhance the Reliable Internet Streaming Transport (RIST) protocol for Multi-Program Transport Streams (MPTS) when sending MPEG Transport Streams.
RIST Transport Stream Program Selection creates a mechanism for the RIST Receiver to tell the RIST Sender what content it needs, said VSF.
Using existing backward-compatible extensions to RIST Main Profile (TR-06-2) and RIST Advanced Profile (TR-06-3) the method enables the RIST Sender to only transmit the programs and/or PIDs required by the RIST Receiver, saving network bandwidth by removing the need to transmit unnecessary programs or PIDs.
According to Dr Ciro Noronha, president of the RIST Forum, the latest ancillary feature optimises network bandwidth usage by allowing the RIST Receiver to tell the Sender what content it needs, avoiding unnecessary transmission. “This is another step in meeting the growing demand for interoperable reliable content transport solutions,” he added
VST has also announced minor updates to RIST Advanced Profile, TR-06-3 and RIST Main Profile, TR-06-2 to mitigate the risk of excessive CPU utilization under some conditions.
More details are available on the VSF website.
