RIST Releases Specification For Source Adaptation
Source Adaptation example.
The Video Services Forum (VSF) has released an ancillary feature that enhances the RIST specifications with source adaptation. This feature, detailed in TR-06-4 Part 1, Source Adaptation, is the first in a series of ancillary features for the RIST Specifications.
One of the core RIST functions is packet loss recovery. However, if the network capacity falls below the stream rate, this situation cannot be handled by loss recovery - the source itself will need to react to keep the stream healthy. The options available to the stream source are to either reduce the bit rate or re-route the stream (if possible). This new Specification defines a protocol for the stream receiver to provide feedback information to the source, so that such actions can be taken.
The RIST protocol is designed to reliably transport video over the Internet for any use case, but is typically used for professional media workflows such as news and sports contribution, remote production, affiliate distribution and primary distribution.
Technical recommendations are freely available from the VSF website for all to download and to use.
