Technical Summary This document defines and registers two new RTCP Source Description items. One, named RtpStreamId, is used for unique identification of RTP streams. The other, RepairedRtpStreamId, can be used to identify which stream a redundancy RTP stream is to be used to repair. It also defines and registers corresponding RTP Header Extension Elements. Working Group Summary The document went through an initial last call, during which there were some objections to the design. The authors and the objectors met together at the Buenos Aires IETF meeting, and worked out a slightly altered design which satisfied everyone. A second last call produced only minor requests for changes, which were addressed, and several people confirmed that they had no issues with the draft. Document Quality The document was reviewed by several AVText members, which resulted in the current design. The mechanism defined by the document is expected to be mandated by WebRTC. It is already implemented in Firefox and is planned to be implemented in Chrome. Personnel The document Shepherd is Jonathan Lennox. The Responsible Area Director is Ben Campbell.
