[MMUSIC] Reply to Liaison statement to IETF concerning 3D video

[Ari Keränen <[e-mail]>]

Here is what we are planning to send as a response to the 3GPP liaison 
request regarding 3D video work at MMUSIC (for details, see 
https://datatracker.ietf.org/liaison/1239/).

Title:    Reply to Liaison statement to IETF concerning 3D video formats 
signalling in SDP

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, however there was not significant interest nor 
technical agreement in the WG for adoption of these items at the time. 
It was also believed that additional 3D video expertise and alignment 
with MPEG would be needed to adequately cover this area. In lieu of the 
above, the work was not adopted.

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
