    Using Codec Control Messages in the RTP Audio-Visual Profile with                       Feedback with Layered Codecs

Abstract

   This document updates RFC 5104 by fixing a shortcoming in the    specification language of the Codec Control Message Full Intra    Request (FIR) description when using it with layered codecs.  In    particular, a decoder refresh point needs to be sent by a media    sender when a FIR is received on any layer of the layered bitstream,    regardless of whether those layers are being sent in a single or in    multiple RTP flows.  The other payload-specific feedback messages    defined in RFC 5104 and RFC 4585 (which was updated by RFC 5506) have    also been analyzed, and no corresponding shortcomings have been    found.
