5.2Joint meeting with 3DG

Discussion and conclusions were reported by the 3DG subgroup. Briefly the discussion was concluded with the agreement to better document, in an MPEG-B non normative annex, the methodology that can check the determinism of a dataflow network specification and can detect time dependent behavior of single FU. This will be considered for the next amendment to MPEG-B standard. The corresponding tool will be included in MPEG-C.

5.3Review of Input contributions

Time	Document No.	Title	Authors
		Notes & Recommendations
T	M19297	Addendum: qualified names and import statements in RVC-CAL	Mickael Raulet , Matthieu Wipliez, Damien de Saint Jorre
		The proposal aims at improving the current handling of import and packages. This can improve the development and clarity of the RVC libraries. The proposed extensions are the proposed solution of the problem investigated by core experiment 7. Such results are supported by Orcc and available for cross-checking and verification as required by the core experiment description. The proposed extensions are approved for inclusion in the WD of MPEG-B amendment 1.
T 15 – 18	m19375	An implementation of dataflow oriented parser within the RVC framework	Mickael Raulet, Mathieu Wipliez, Damien de Saint Jorre
		The contribution provides an example of dataflow oriented parser for the Constrained Baseline Profile. For the Progressive High profile additional work is needed to include CABAC. Before considering inclusion in MPEG-C a more complete testing need to be done.
	m19383	Comparative study on performance of C code automatically generated by Orcc from RVC-CAL code	Junaid Ahmad, Shujun Li
		The contribution provides a comparison of performance between reference SW of cryptographic algorithms and C code generated from RVC-CAL. The results reportedly show that the dataflow generated code performance is comparable to generic reference SW implementations.

An AHG was appointed (N11826, as recorded in N11700) to further the work until the 96th meeting.

63DV, MFC, and "Option 1" video coding

Work toward development of calls for proposals on 3D video coding, MPEG frame-compatible (MFC) scalable resolution enhancement of stereo 3D video, and "Option 1" video coding was conducted under the Requirements subgroup and is reported in the report of that subgroup.

Summary

The Joint Collaborative Team on Video Coding (JCT-VC) of ITU-T WP3/16 and ISO/IEC JTC 1/SC 29/WG 11 held its fourth meeting during 20-28 January, 2011 at the Hotel Inter-Burgo EXCO in Daegu, Republic of Korea. The JCT-VC meeting was held under the chairmanship of Dr. Gary Sullivan (Microsoft/USA) and Dr. Jens-Rainer Ohm (RWTH Aachen/Germany).

The JCT-VC meeting sessions began at approximately 9:10 a.m. on Thursday 20 January. Meeting sessions were held on all days (including weekend days) until the meeting was closed at approximately 1:55 p.m. on Friday 28 January. Approximately 248 people attended the JCT-VC meeting, and more than 400 input documents were discussed. The meeting took place in a co-located fashion with a meeting of ISO/IEC JTC 1/SC 29/WG 11 (MPEG) – one of the two parent bodies of the JCT-VC. The subject matter of the JCT-VC meeting activities consisted of work on the new next-generation video coding standardization project now referred to as High Efficiency Video Coding (HEVC).

The primary goals of the meeting were to review the work that was performed in the interim period since the third JCT-VC meeting in implementing the HEVC Test Model (HM), review results from Core Experiments (CE), review technical input documents, further develop Working Draft and HEVC Test Model (HM), and plan a new set of Core Experiments (CEs) for further investigation of proposed technology.

The JCT-VC produced three particularly important output documents from the meeting: the HEVC Test Model 2 (HM2), the HEVC specification Working Draft 2 (WD2), and a document specifying common conditions and software reference configurations for HEVC coding experiments. Moreover, 14 documents describing the planning of CEs were drafted.

For the organization and planning of its future work, the JCT-VC established eighteen "Ad Hoc Groups" (AHGs) to progress the work on particular subject areas. The next JCT-VC meeting will be held during during 16-23 March 2011 in Geneva, Switzerland under the auspices of ITU-T Q6/16. Subsequent meetings are planned to be held during 14-22 July 2011 under WG 11 auspices in Torino, IT, 22-30 November 2011 under ITU-T auspices in Geneva, CH, and 1-10 February 2012 under WG 11 auspices in San José, USA.

The document distribution site http://phenix.it-sudparis.eu/jct/ was used for distribution of all documents.
