JVET-M1033 Description of Core Experiment 13 (CE13): Neural-network based loop filtering [Y. Li, S. Liu, K. Kawamura]

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-M0025 CE5: Summary report on the Arithmetic Coding Engine [H. Kirchhoffer, A. Said]

This is the summary report of Core Experiment 5 (CE5) on the Arithmetic Coding Engine. Subtest 1 (experiments CE5.1.1 – 5.1.13) addresses the effect on the compression efficiency of training parameters of the probability estimation stage of the proposed arithmetic coding engines. Subtest 2 addresses the achievable throughput of the different coding engines of subtest 1 in an optimized software implementation. Subtest 3 provides a summary of the analysis of hardware implementation aspects.

The experiments were implemented in separate branches in the following git repository:

https://vcgit.hhi.fraunhofer.de/JVET-L-CE5/VVCSoftware_VTM.git

For subtest 2, a testbed is available in branch CE5.2, which contains throughput-optimized software implementations of the coding engines of subtest 1.

The following table lists all tests that were performed in this CE and gives a summary of the tools.

Note on the naming convention of CE tests: ‘CE5.x.y.z’ means ‘CE5.x.y’ as specified in the CE5 description with configuration ‘z’ according to the following tables.
