Source-Specific Media Attributes in the Session Description Protocol
RFC 5576, “Source-Specific Media Attributes in the Session Description Protocol”, is a Proposed Standard document published in June 2009 by J. Lennox, J. Ott, T. Schierl. The canonical text is published by the RFC Editor.
Abstract
The Session Description Protocol (SDP) provides mechanisms to describe attributes of multimedia sessions and of individual media streams (e.g., Real-time Transport Protocol (RTP) sessions) within a multimedia session, but does not provide any mechanism to describe individual media sources within a media stream. This document defines a mechanism to describe RTP media sources, which are identified by their synchronization source (SSRC) identifiers, in SDP, to associate attributes with these sources, and to express relationships among sources. It also defines several source-level attributes that can be used to describe properties of media sources. [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.
