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 H.271 Video
Back Channel, Full Intra Request, Temporary Maximum Media Stream Bit Rate
and Temporal Spatial Trade-off.
Working Group Summary
The document has been reviewed by the AVT working group to ensure

desire to implement these mechanisms.
