This document specifies a few extensions to the messages defined in
the Audio-Visual Profile with Feedback (AVPF).  They are helpful
primarily in conversational multimedia scenarios where centralized
multipoint functionalities are in use.  However, some are also
usable in smaller multicast environments and point-to-point calls.

The extensions discussed are messages related to the ITU-T Rec. H.271
Video Back Channel, Full Intra Request, Temporary Maximum Media
Stream Bit Rate, and Temporal-Spatial Trade-off.  [STANDARDS TRACK]
