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

call produced only minor requests for changes, which were
addressed, and several people confirmed that they had no issues
with the draft.
