This update addresses comments received at the virtual interim, as well as aligning with the RID draft (draft-pthatcher-mmusic-rid-02), and also aligns use case text with what the solution actually describes. Summary on edits, from the draft: o Removed text on multicast / broadcast from use cases, since it is not supported by the solution. o Removed explicit references to unified plan draft. o Added possibility to initiate simulcast streams in paused mode. o Enabled an offerer to offer multiple stream identification (pt or rid) methods and have the answerer choose which to use. o Added a preference indication also in send direction offers. o Added a section on limitations of the current proposal, including identification method specific limitations. > -----Original Message----- > From: mmusic [mailto:mmusic-bounces@ietf.org] On Behalf Of internet-drafts@ietf.org > Sent: den 20 oktober 2015 01:36 > To: i-d-announce@ietf.org > Cc: mmusic@ietf.org > Subject: [MMUSIC] I-D Action: draft-ietf-mmusic-sdp-simulcast-03.txt > > > A New Internet-Draft is available from the on-line Internet-Drafts directories. > This draft is a work item of the Multiparty Multimedia Session Control Working Group of the IETF. > > Title : Using Simulcast in SDP and RTP Sessions > Authors : Bo Burman > Magnus Westerlund > Suhas Nandakumar > Mo Zanaty > Filename : draft-ietf-mmusic-sdp-simulcast-03.txt > Pages : 25 > Date : 2015-10-19 > > Abstract: > In some application scenarios it may be desirable to send multiple > differently encoded versions of the same media source in different > RTP streams. 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 of a new media > level SDP attribute that expresses capability to send and/or receive > simulcast RTP streams.
