Grouping of Media Lines in the Session Description Protocol
RFC 3388, “Grouping of Media Lines in the Session Description Protocol”, is a Proposed Standard document published in December 2002 by G. Camarillo, G. Eriksson, J. Holler, H. Schulzrinne. It has been obsoleted by RFC 5888 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document defines two SDP attributes: 'groupe' and 'mid'. They allow to group together several 'm' lines for two different purposes: for lip synchronization and for receiving media from a single flow (several media streams), encoded in different formats during a particular session, in different ports and host interfaces.
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.
