Technical Summary Source Description (SDES) items are normally transported in the RTP control protocol (RTCP). In some cases it can be beneficial to speed up the delivery of these items. Mainly when a new source (SSRC) joins an RTP session and the receivers needs this source's identity, relation to other sources, or its synchronization context, all of which may be fully or partially identified using SDES items. To enable this optimization, this document specifies a new RTP header extension that can carry SDES items. Working Group Summary The document went through working group last call. Several people commented during last call that they had read the document but had no issues with its content. Document Quality The document got good reviews from AVText members. The document generalizes a mechanism which is used by the SDP BUNDLE mechanism, which required for all WebRTC implementations. Personnel The document Shepherd is Jonathan Lennox. The Responsible Area Director is Ben Campbell.
