2. Resolutions

It was expressed that the clarified BSD license should be OK for future work in Video and JCTs.

It was agreed to convert the SCC extension draft for HEVC to DIS (instead of DAM) and not to plan to publish 3D-HEVC, rather including it in the new edition.

Parser instantiation as new edition

Massimo was appointed as an additional editor for 15938-14.

3. AHGs established

   – JCT-VC report

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 twenty-first meeting during 19–26 June 2015 at the Mariott Hotel Warsaw in Warsaw, Poland. The JCT-VC meeting was held under the chairmanship of Dr Gary Sullivan (Microsoft/USA) and Dr Jens-Rainer Ohm (RWTH Aachen/Germany). For rapid access to particular topics in this report, a subject categorization is found (with hyperlinks) in section 1.14 of this document.

The JCT-VC meeting sessions began at approximately 0900 hours on Friday 19 June 2015. Meeting sessions were held on all days (including weekend days) until the meeting was closed at approximately 12:40 hours on Friday 26 June 2015. Approximately 91 people attended the JCT-VC meeting, and approximately 150 input documents were discussed. The meeting took place in a collocated fashion with a meeting of WG11– one of the two parent bodies of the JCT-VC. The subject matter of the JCT-VC meeting activities consisted of work on the video coding standardization project known as High Efficiency Video Coding (HEVC) and its extensions.

One primary goal of the meeting was to review the work that was performed in the interim period since the twentieth JCT-VC meeting in producing:

• 
  The HEVC test model (HM) 16 improved encoder description (including RExt modifications) update 2;
  
• 
  Verification test plan for format range extensions and interlaced video;
  
• 
  The RExt reference software draft 2 and conformance testing draft 4, the latter combined with improved version 1 conformance testing;
  
• 
  The SHVC reference software draft 1, conformance testing draft 2 and SHM test model 9;
  
• 
  For HEVC screen content coding (SCC) extensions, the HEVC screen content coding test model 4, SCC draft text 3, and a document specifying common test conditions and software reference configurations for SCC experiments.
  

The other most important goals were to review the results from two Core Experiments on Screen Content Coding (CE1–2), and review other technical input documents. Reviewing the progress made towards definition of screen content coding tools was the most important topic of the meeting. Advancing the work on development of conformance and reference software for recently finalized HEVC extensions (RExt, SHVC) is also a significant goal. Further preparation of verification tests was conducted. Possible needs for corrections to version 2 were also considered.

In addition to one new experiment plan description in screen content coding, the JCT-VC produced 11 other particularly important output documents from the meeting:

• 
  The HEVC test model (HM) 16 improved encoder description (including RExt modifications) update 3;
  
• 
  The verification test report for format range extensions and interlaced video;
  
• 
  For the format range extensions (RExt), the RExt reference software draft 3 and conformance testing draft 5, the latter combined with improved version 1 conformance testing;
  
• 
  For the scalable extensions (SHVC), the SHVC reference software draft 2, conformance testing draft 3, SHVC test model 10 (SHM 10), and draft verification test plan for SHVC;
  
• 
  For the HEVC screen content coding (SCC) extensions, the HEVC screen content coding test model 5 (SCM 5), SCC draft text 4, and a document specifying common test conditions and software reference configurations for SCC experiments.
  

For the organization and planning of its future work, the JCT-VC established 13 "ad hoc groups" (AHGs) to progress the work on particular subject areas. The next four JCT-VC meetings are planned for Thu. 15 – Wed. 21 Oct. 2015 under ITU-T auspices in Geneva, CH, Fri. 19 – Fri. 26 Feb. 2016 under WG 11 auspices in San Diego, US, Thu. 26 May – Wed. 1 June 2016 under ITU-T auspices in Geneva, CH, and Fri. 14 – Fri. 21 Oct. 2016 under WG 11 auspices in Chengdu, CN.
