Liaisons referred by this one Liaison statement to IETF concerning 3D video formats signalling in SDP
Body
Source: IETF MMUSIC WG
To:     TSG-SA WG4

The MMUSIC Working Groups thanks SA4 for their information request around work related to SDP signaling of 3D video formats. At the present time, the MMUSIC WG does not have any active work in this area.

For your information, the MMUSIC WG did previously (in 2012) consider work in this area based on the following 3 documents:

http://datatracker.ietf.org/doc/draft-capelastegui-mmusic-3dv-sdp/
http://datatracker.ietf.org/doc/draft-greevenbosch-mmusic-sdp-parallax/
http://datatracker.ietf.org/doc/draft-greevenbosch-mmusic-sdp-3d-format/

The drafts were presented in a couple of meetings and discussed on the MMUSIC mailing list. While work was initially being pursued, there was ultimately not sufficient interest or technical agreement in the WG for continued work and adoption of these items. It was also believed that additional 3D video expertise and alignment with JCT-3V, MPEG and ITU-T Q6/16 (VCEG) would be needed to adequately cover this area. In lieu of the above, the work did not proceed.

The MMUSIC WG would welcome further input from SA WG4 on this matter.

Next IETF meetings:
- IETF 87 July 28 - August 2, 2013, Berlin, Germany
- IETF 88 November 3-8, 2013, Vancouver, BC, Canada
