Codec Control Messages in the RTP Audio-Visual Profile with Feedback
RFC 5104, “Codec Control Messages in the RTP Audio-Visual Profile with Feedback”, is a Proposed Standard document published in February 2008 by S. Wenger, U. Chandra, M. Westerlund, B. Burman. It has since been updated by RFC 7728, RFC 8082. The canonical text is published by the RFC Editor.
Abstract
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]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
