323002 MPEG-C Video Technologies

3.123001-4 and 23002-4 Reconfigurable Video Coding (RVC)

3.1.1General status of work

The two parts related to RVC (ISO/IEC 23001-4 Codec Configuration Representation in MPEG-B and ISO/IEC FCD 23002-4 Video Tool Library in MPEG-C) were progressed into FCD status in April with editorial period, and delivered in time for the ballots, which will be closing before the October meeting (where it is planned to promote both parts for FDIS). The main issue of work during the week in the RVC breakout group was related to editorial improvements on both texts (see items below). Study documents were drafted. Main issues still to be resolved are the relationship of RVC-BSDL as defined in 23001-4 with BSDL (should it restrict the usage of BSDL elements that are not currently needed for RVC context?), and the proper definition of tools in 23002-4 (usually only input-output behaviour of FUs needs to be normative, but some FUs are described in a fashion of sequential algorithms internally; furthermore, careful checking is necessary about whether the FU descriptions are precisely equivalent to the elements of the MPEG standards from which they were drawn).

While the FDIS as planned for October will give full support only for MPEG-2 main profile, MPEG-4 simple profile and MPEG-4 AVC baseline profile, further tools for MPEG-4 advanced simple profile, AVC high profile and SVC will be supported in Amd.2, for which the second version of WD was issued. Likewise, WD 2 of software and conformance amendment (Amd.1) was also produced.
To clarify the relationships of MPEG and non-MPEG FUs / toolboxes that could both be used in the RVC context, a document entitled RVC vision (N9990) was issued which clearly expresses that only the elements defined by MPEG (in 23001-4 and 23002-4) are handled as MPEG compliant, while usage of non-MPEG tools is under sole responsibility of their respective users.
