1.1Organization

The ITU-T/ISO/IEC Joint Collaborative Team on Video Coding (JCT-VC) is a group of video coding experts from the ITU-T Study Group 16 Visual Coding Experts Group (VCEG) and the ISO/IEC JTC 1/ SC 29/ WG 11 Moving Picture Experts Group (MPEG). The parent bodies of the JCT-VC are ITU-T WP3/16 and ISO/IEC JTC 1/SC 29/WG 11.

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 third meeting during 7-15 October, 2010 at the Guangzhou Baiyun International Convention Center – Oriental International Convention Hotel, in Guangzhou, China. The JCT-VC meeting was held under the chairmanship of Dr. Gary Sullivan (Microsoft/USA) and Dr. Jens-Rainer Ohm (RWTH Aachen/Germany).

1.2Meeting logistics

The JCT-VC meeting sessions began at approximately 9:00 a.m. on Thursday 7 October. Meeting sessions were held on all days (including weekend days) until the meeting was closed at approximately 1:30 p.m. on Friday 15 October. Approximately 244 people attended the JCT-VC meeting, and approximately 300 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).

Information regarding logistics arrangements for the meeting had been provided at http://avslab.org/news/mpeg.

1.3Primary goals

The primary goals of the meeting were to review the work that was performed in the interim period since the second JCT-VC meeting in implementing the Test Model under Consideration (TMuC), review results from Tool Experiments (TE), review technical input documents, and establish a first Working Draft and HEVC Test Model (HM).

1.4Documents

The documents of the JCT-VC meeting are listed in Annex A of this report. The documents can be found at http://phenix.it-sudparis.eu/jct/.

The formal deadline for registering and uploading non-administrative contributions was October 1, 2010. Some confusion over document handling occurred as the result of the transition to a new electronic document archive site just prior to the meeting.

Documents with numbers JCTVC-C295 through JCTVC-C320 were all registered after October 2 and uploaded after October 3 (based on the timestamps of the document archive site, which appear to correspond to the local time zone of Paris, France), of which only JCTVC-C296, JCTVC-C297, JCTVC-C299, JCTVC-C301, JCTVC-C302 and JCTVC-C303 were available by the first meeting day. Four of these (JCTVC-C310, JCTVC-C317, JCTVC-C319, and JCTVC-C320) were summary reports or side-activity reports generated during the meeting and thus should not necessarily be considered late. The majority of the others were cross-verification reports.

Among the other documents, JCTVC-C030, JCTVC-C068, JCTVC-C114, JCTVC-C165, JCTVC-C174, JCTVC-C175, JCTVC-C178, JCTVC-C179, JCTVC-C180, JCTVC-C181, JCTVC-C182, JCTVC-C225, JCTVC-C231, JCTVC-C244, JCTVC-C247, JCTVC-C248, JCTVC-C287, JCTVC-C288 and JCTVC-C292 had been uploaded after October 3 (based on the timestamps of the document archive site, which appear to correspond to the local time zone of Paris, France), but had been uploaded in some form by the first day of the meeting. Documents JCTVC-C272 and JCTVC-C284 were missing prior to the meeting and were provided by the third meeting day during the meeting. Documents JCTVC-C243, JCTVC-C308, and JCTVC-C309, all of which were cross-verification experiment reports, were only uploaded substantially after the meeting had ended.

Registration timestamps, initial upload timestamps, and final upload timestamps are listed in Annex A of this report. These timestamps reflect activity on the new document site, and some documents had been uploaded (and in some cases, made available for distribution) on the prior document site before being placed on the new document site. The timestamps of the document archive site appear to correspond to the local time zone of Paris, France.

Documents JCTVC-C289, JCTVC-290 and JCTVC-291 were available, but were initially missing an IPR statement.

As a general policy, missing documents were not to be presented, and late documents (and substantial revisions) could only be presented when sufficient time for studying was given after the upload. This policy was not strictly enforced at this meeting in a few cases – partly because of the transition to the use of a new document archive site and partly because there were network access difficulties during the meeting – although some late documents were not presented due to lack of time for their presentation. Otherwise, there were no objections raised by the group regarding presentation of late contributions. The situation about missing input documents must be significantly improved in upcoming meetings.

An issue discussed at the meeting was what to do in the case of a submission of a "placeholder" contribution document that is basically empty of content, with perhaps only a brief abstract and some indication of an intent to provide a more complete submission as a revision. It was agreed that such submissions do not seem to be constructive, and should be rejected if there is a way to do this in the document handling interface; as such submissions seem to be an attempt to avoid a submission being identified as late while not providing adequate content for study by the participants.

Contribution document registrations JCTVC-C069, JCTVC-C107, JCTVC-C133, JCTVC-C151, JCTVC-C177, JCTVC-C221, JCTVC-C222, JCTVC-C242, and JCTVC-C294 were withdrawn (no documents had been provided, or an incomplete document had been provided, or the registration to JCT-VC had been made in error when intending to submit a document to the WG11 parent body instead).

The report documents of the previous meeting, particularly the meeting report JCTVC-B200, the draft TMuC encoder description JCTVC-B204 and decoder specification JCTVC-B205 were approved. Draft versions 6 and 7 of JCTVC-B205 were made available by Saturday.
