Future meeting plans, expressions of thanks, and closing of the meeting

Future meeting plans were established according to the following guidelines:

• Meeting under ITU-T SG 16 auspices when it meets (starting meetings on the Tuesday of the first week and closing it on the Wednesday of the second week of the SG 16 meeting – a total of 9 meeting days), and
• Otherwise meeting under ISO/IEC JTC 1/SC 29/WG 11 auspices when it meets (starting meetings on the Wednesday prior to such meetings and closing it at lunchtime on the last day of the WG 11 meeting – a total of 9.5 meeting days).

In cases where an exceptionally high workload is expected for a meeting, an earlier starting date may be defined.

Some specific future meeting plans (to be confirmed) were established as follows:

• Tue. 19 – Wed. 27 March 2019, 14^th meeting under ITU-T auspices in Geneva, CH.
• Wed. 3 – Fri. 12 July 2019, 15^th meeting under WG 11 auspices in Gothenburg, SE.
• Tue. 1 – Wed. 9 October 2019, 16^th meeting under ITU-T auspices in Geneva, CH.
• Wed. 8 – Fri. 17 January 2020, 17^th meeting under WG 11 auspices in Brussels, BE.

The agreed document deadline for the 14^th JVET meeting was planned to be Tuesday 12 March 2019. Plans for scheduling of agenda items within that meeting remained TBA.

WG 11, the local hosting organization Ecole Mohammadia d’Ingénieurs (EMI) – Mohammed V University, Rabat, Morocco, and Abdellatif Benjelloun Touimi were thanked for the excellent hosting and organization of the 13^th ...

JVET-M0023 CE3: Summary report on intra prediction and mode coding [G. Van der Auwera, J. Heo, A. Filippov]

This contribution was discussed Wednesday 9 January 1750–2030 (chaired by GJS)

This is the summary report of the third Core Experiment (CE3). The goal of CE3 is to study intra prediction tools, including mode coding, for potential inclusion into the VVC standard.

The following is the list of defined sub-tests in CE3:

• CE3.1: Intra prediction modes (5 tests)
• CE3.2: Cross-component prediction (11 tests)
• CE3.3: Intra mode coding (10 tests)

This document summarizes the objective results (BD-rates, runtimes), cross-check reports, and related input contributions.

The source codes of the tests and full test results are uploaded by proponents into the following CE3 GitLab repository:

https://vcgit.hhi.fraunhofer.de/JVET-L-CE3/VVCSoftware_VTM.git

The following changes were made to the CE3 test description document after the T2 deadline (December 6, 2018) had passed. Besides changes to contact persons and assignment of cross-checkers, the following changes were requested on the JVET reflector and discussed for clarification, if needed:

• CE3.2:
  • Added test CE3.2.2.1 (MMLM; combination of tests CE3.2.1 and CE3.2.2)
  • Added test CE3.2.6.2 (CCLM; testing 3 columns of neighbouring samples on left side of block, 1 row above block)
• CE3.3:
  • Reduction and clarification of test CE3.3.1 from 7 subtests to 4 (decoder-side intra mode derivation)
  • Additional result for test 3.5 (multiple DM for chroma)
