Abstract
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.
Meeting Notes
JVET-W0001 JVET AHG report: Project management (AHG1) [J.-R. Ohm, G. J. Sullivan]

The work of the JVET overall had proceeded well in the interim period with approximately same number of input documents (as compared to the previous meeting) 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 initially available at the JVET web site (https://jvet-experts.org/) or the ITU-based JVET site (http://wftp3.itu.int/av-arch/jvet-site/2021_04_V_Virtual/). It is noted that the previous document site http://phenix.int-evry.fr/jvet/ is still accessible, but was converted to read-only.

The list of documents produced included the following, particularly:

  • The meeting report (JVET-V1000) [Posted 2021-05-27]
  • High Efficiency Video Coding (HEVC) Test Model 16 (HM 16) Encoder Description Update 15 (JVET-V1002) [Posted 2021-07-06]
  • Errata report items for VVC, HEVC, AVC, Video CICP, and CP usage TR (JVET-V1004) [Posted 2021-06-24]
  • Algorithm description for Versatile Video Coding and Test Model 13 (VTM 12) (JVET-V2002) [Posted 2021-07-06]
  • VVC operation range extensions (Draft 3) (JVET-V2005) [Posted 2021-05-07]
  • Additional SEI messages for VSEI (Draft 3) (JVET-V2006) [Posted 2021-05-07]
  • VTM common test conditions and evaluation procedures for HDR/WCG video (JVET-V2011) [Posted 2021-05-14]
  • Common Test Conditions and evaluation procedures for neural network-based video coding technology (JVET-V2016) [Posted 2021-05-26, last update 2021-06-05]
  • Common Test Conditions and evaluation procedures for enhanced compression tool testing (JVET-V2017) [Posted 2021-05-15]
  • VVC verification test report for HD SDR and 360° video content (JVET-V2020) [Posted 2021-06-22]
  • VVC verification test plan (Draft 6) (JVET-V2021) [Posted 2021-06-24]
  • CE on Entropy Coding for High Bit Depth and High Bit Rate Coding (JVET-V2022) [Posted 2021-04-28, last update 2021-05-15]
  • EE on Neural Network-based Video Coding (JVET-V2023) [Posted 2021-04-28, last update 2021-05-14]
  • EE on Enhanced Compression beyond VVC capability (JVET-V2024) [Posted 2021-04-27, last update 2021-05-22]

The twelve ad hoc groups had made progress, and reports from those activities had been submitted. Furthermore, one core experiment (CE) on entropy coding for high bit depth and high bit rate coding, and two exploration experiments (EE) on neural network-based video coding and on enhanced compression beyond VVC capability, were conducted.

Due to issues associated with the COVID-19 pandemic, a conversion of the meeting to be conducted only online was again necessitated.

During the interim period, one meeting of AHG4 (for preparing the HDR verification tests) was held.

Software integration 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 90 input contributions (not counting the AHG, CE and EE summary reports and crosschecks) had been registered for consideration at the current meeting.

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 report(s),
  • Maintenance and minor enhancement work on the Advanced Video Coding (AVC) standard, associated conformance test sets and reference software.

To retain a consistent numbering scheme, the number range of output documents starting from 1001 was reserved for the previous JCT-VC topic items listed above, whereas the number range starting from 2001 was retained for VVC, VSEI and future exploration activities. Duplication of AHGs was avoided by merging previous JCT-VC AHGs with the corresponding AHGs of JVET.

A preliminary basis for the document subject allocation and meeting notes for the 23rd meeting had been made publicly available on the ITU-hosted ftp site http://wftp3.itu.int/av-arch/jvet-site/2021_07_W_Virtual/.
