This is called simulcast. This document discusses the best way of accomplishing simulcast in RTP and how to signal it in SDP. A solution is defined by making an extension to SDP, and using RTP/RTCP identification methods to relate RTP streams belonging to the same media source. The SDP extension consists a new media level SDP attribute that express capability to send and/or receive simulcast RTP streams. One part of the RTP/RTCP identification method is included as a reference to a separate document, since it is useful also for other purposes.}, }
