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.
