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 Full Intra Request, Temporary Maximum Media Bit-rate and Temporal Spatial Trade-off.
