JVET-N0001 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 huge 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.it-sudparis.eu/jvet/) or the ITU-based JVET site (http://wftp3.itu.int/av-arch/jvet-site/2019_01_ M_Marrakech/ ), particularly including the following:

• The meeting report (JVET-M1000) [Posted 2019-03-18]
• Versatile Video Coding (Draft 4) (JVET-M1001) [Posted 2019-02-01, last update 2019-03-17]
• Algorithm description for Versatile Video Coding and Test Model 4 (VTM 4) (JVET-M1002) [Posted 2019-02-16]
• Algorithm descriptions of projection format conversion and video quality metrics in 360Lib Version 9 (JVET-M1004) [Posted 2019-02-17]
• Methodology and reporting template for coding tool testing (JVET-M1005) [Posted 2019-01-30]
• Methodology and reporting template for neural network coding tool testing (JVET-M1006) [Posted 2019-01-30]
• JVET common test conditions and software reference configurations (JVET-M1010) [Posted 2019-02-07]
• Description of CE 1..13 (JVET-M1021..35) [all first posted 2019-01-18, further updates during the CE definition period of 3 weeks after the meeting, until 2019-02-08]. The following CE description documents had later updates (more than 4 weeks after the meeting):
  • • JVET-M1022 [last updated 2019-03-15]
    • JVET-L1023 [last updated 2019-03-14]
    • JVET-L1024 [last updated 2019-03-17]
    • JVET-L1026 [last updated 2019-03-14]
    • JVET-L1028 [last updated 2019-02-28]
    • JVET-L1029 [last updated 2019-03-14]
    • JVET-L1030 [last updated 2019-03-17]

The nineteen ad hoc groups had made progress, and reports from those activities had been submitted.

Software integration of VTM was finalized approximately according to the plan.

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 600 input contributions to the current meeting (not counting the AHG and CE summary reports) had been registered for consideration at the meeting. Though topics of Core Experiments and related documents for the development of low-level coding tools reflect the bulk of these documents, around 70 documents were submitted on aspects of high-level syntax, including tile partitioning.

A preliminary basis for the document subject allocation and meeting notes for the 14th meeting had been made publicly available on the ITU-hosted ftp site.

Discussed aspects:

• The draft text version was draft 4, although the AHG report incorrectly referred to it as draft 3.
• It was said that the draft text might still be updated (which did not occur).
• It was asked whether another version of the VTM would be released (which did not occur).
• It was noted that CE4 and CE9 had some late clarifications.
• It was noted that there were 78 contributions on high-level syntax, a substantial increase.
