Meeting Report of the 7^th meeting of the Joint Video Exploration Team (JVET)

The Joint Video Exploration Team (JVET) of ITU-T WP3/16 and ISO/IEC JTC 1/ SC 29/ WG 11 held its seventh meeting during 13–21 July 2017 at the Politecnico di Torino, Torino, IT. The JVET meeting was held under the leadership of Dr Gary Sullivan (Microsoft/USA) and Dr Jens-Rainer Ohm (RWTH Aachen/Germany) as responsible coordinators of the two organizations. For rapid access to particular topics in this report, a subject categorization is found (with hyperlinks) in section ‎1.14 of this document. The JVET meeting sessions began at approximately 0900 hours on Thursday 13 July 2017. Meeting sessions were held on all days (including weekend days) until the meeting was closed at approximately 1313 hours on Friday 21 July 2017. Approximately 180 people attended the JVET meeting, and approximately 121 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 JVET. The subject matter of the JVET meeting activities consisted of studying future video coding technology with a compression capability that significantly exceeds that of the current HEVC standard, or gives better support regarding the requirements of newly emerging application domains of video coding.

As a primary goal, the JVET meeting performed an evaluation of compression technology designs proposed in this area, which had been received in response to the Call for Evidence (CfE) as issued by the previous meeting. Another important goal of the meeting was to review the work that was performed in the interim period since the sixth JVET meeting in producing the Joint Exploration Test Model 6 (JEM6). Video coding results produced with JEM6 had also been included as anchor in the CfE. Furthermore, results from four exploration experiments conducted in the JEM6 framework were reviewed, and other technical input was considered. On this basis, modifications towards JEM7 were planned.For the organization and planning of its future work, the JVET established 10 “ad hoc groups” (AHGs) to progress the work on particular subject areas. 3 Exploration Experiments (EE) were defined on particular subject areas of coding tool testing. The next four JVET meetings are planned for Wed. 18. – Wed. 25 Oct. 2017 under ITU-T auspices in Macao, CN, during Fri. 19 – Fri. 26 Jan. 2018 under WG 11 auspices in Gwangju, KR, during 11 – 20 April 2018 in San Diego, US, and during 10 – 18 July 2018 under ITU-T auspices in Ljubljana, SI.The JVET meeting sessions began at approximately 0900 hours on Thursday 13 July 2017.

As this unveiled significant evidence about existence of promising technology, a Draft Call for Proposals was issued, which is intended to be finalized by the October 2017 meeting. Another important goal of the meeting was to review the work that was performed in the interim period since the sixth JVET meeting in producing the Joint Exploration Test Model 6 (JEM6).

The preliminary notes were also circulated publicly by ftp during the meeting on a daily basis. It should be understood by the reader that 1) some notes may appear in abbreviated form, 2) summaries of the content of contributions are often based on abstracts provided by contributing proponents without an intent to imply endorsement of the views expressed therein, and 3) the depth of discussion of the content of the various contributions in this report is not uniform. Generally, the report is written to include as much information about the contributions and discussions as is feasible (in the interest of aiding study), although this approach may not result in the most polished output report.
