JVET-T0001 JVET AHG report: Project management (AHG1) [J.-R. Ohm, G. J. Sullivan]
This document reports on the work of the JVET ad hoc group on Project Management, including an overall status report on the VVC standardization project and the progress made during the interim period since the preceding meeting.
The work of the JVET overall had proceeded well in the interim period with a moderate number of input documents submitted to the current meeting. Intense discussion had been carried out on the group email reflector, and all output documents from the preceding meeting had been produced.
Output documents from the preceding meeting had been made available at the "Phenix" site (http://phenix.int-evry.fr/jvet/) or the ITU-based JVET site (http://wftp3.itu.int/av-arch/jvet-site/2020_06_S_Virtual/), particularly including the following:
- The meeting report (JVET-S2000) [Posted 2020-10-07]
- Versatile Video Coding (Draft 10) (JVET-S2001) [Posted 2020-06-23, last update 2020-09-04]
- Algorithm description for Versatile Video Coding and Test Model 10 (VTM 10) (JVET-S2002) [Posted 2020-08-12]

- Methodology and reporting template for coding tool testing (JVET-S2005) [Posted 2020-07-20]
- Supplemental enhancement information messages for coded video bitstreams (Draft 5) (JVET-S2007) [Posted 2020-06-29, last update 2020-09-04]
- Conformance testing for Versatile Video Coding (Draft 4) (JVET-S2008) [Posted 2020-10-06]
- Verification test plan (Draft 3) (JVET-S2009) [Posted 2020-07-11, last update 2020-07-31]
- JVET common test conditions and evaluation procedures for HDR/WCG video (JVET-S2011) [Posted 2020-07-23]
- Working practices using objective metrics for evaluation of video coding efficiency experiments (Draft 3) (JVET-S2016) [Posted 2020-07-10]
- Technologies under consideration for VSEI (JVET-S2017) [Posted 2020-08-05]
As a major achievement, JVET-S2001 was submitted to the parent bodies for publication as ITU-T Rec. H.266, and ISO/IEC FDIS 23090-3. Likewise, JVET-S2007 was submitted for publication as ITU-T Rec. H.274, and ISO/IEC FDIS 23002-7.
The thirteen ad hoc groups had made progress, and reports from those activities had been submitted.
Due to issues associated with the COVID-19 pandemic, a conversion of the meeting to be conducted only online was necessitated.
During the interim period, meetings of AHG4 (for preparing the verification tests) and AHG11 (for discussing aspect of neural network-based video coding) were held.
Software integration of VTM was finalized approximately according to the plan. Significant activities were also conducted on preparation of verification tests, and on development of VVC conformance testing.
Various problem reports relating to asserted bugs in the software, draft specification text, and reference encoder description had been submitted to an informal "bug tracking" system. That system is not intended as a replacement of our ordinary contribution submission process. However, the bug tracking system was considered to have been helpful to the software coordinators and text editors. The bug tracker reports had been automatically forwarded to the group email reflector, where the issues were discussed – and this is reported to have been helpful.
Roughly 60 input contributions to the current meeting (not counting the AHG summary reports and crosschecks) had been registered for consideration at the meeting. No CEs had been conducted.
It is further noted that, starting from the twentieth JVET meeting, work items which had originally been conducted by the Joint Collaborative Team on Video Coding (JCT-VC) were continued to be conducted in JVET as a single joint team, as negotiated by the parent bodies. This particularly consists of work on
- High Efficiency Video Coding (HEVC) and its extensions, the development of associated conformance test sets, reference software, verification testing, and non-normative guidance information,
- Specification of Coding-independent Code Points (Video) (CICP), and associated technical reports,
- Maintenance and minor enhancement work on the Advanced Video Coding (AVC) standard, associated conformance test sets and reference software.
Consequently, reports of the 5 AHGs which had been established at the 40th JCT-VC meeting were also submitted to JVET.
A preliminary basis for the document subject allocation and meeting notes for the 20th meeting had been made publicly available on the ITU-hosted ftp site http://wftp3.itu.int/av-arch/jvet-site/2020_10_T_Virtual/.
