16th Meeting: Geneva, October 2019 2019-09-25 08:29
Abstract
In low latency encoding, ALF coefficients can be derived from the currently encoded picture without using in the current picture but are signaled in APS for the use in the next pictures. In this case, APS should be signaled after the last VCL NAL unit to keep the TemporalID of the access unit, however according to the current specification draft such order of NAL units is not allowed. APS can be sent only before the last VCL NAL unit, which in this case belongs to the next access unit with potentially having higher TemporalID.

Abstract
The goal of this Core Experiment (CE) is to improve and/or enhance cross component loop filtering (CC-ALF) techniques. These CC-ALF techniques will be evaluated according to both subjective and objective metrics.

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 (ordinarily 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 (ordinarily starting meetings on the Tuesday 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. For the upcoming meeting in October 2019, the SG16 parent-level meeting dates had been shifted after the JVET and MPEG meeting plans were established, which has caused an additional adjustment in the JVET dates.

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

  • Tue. 7 – Fri. 17 January 2020, 17th meeting under WG 11 auspices in Brussels, BE.
  • Wed. 15 – Fri. 24 April 2020, 18th meeting under WG 11 auspices in Alpbach, AT.
  • Tue. 23 June – Wed. 1 July 2020, 19th meeting under ITU-T auspices in Geneva, CH.
  • Wed. 7 – Fri. 16 October 2020, 20th meeting under WG 11 auspices in Rennes, FR.

The agreed document deadline for the 17thJVET meeting was planned to be Tuesday 31 December...

JVET-P1033 Report of BoG on CE5-related loop filter proposals [A. Norkin, C.-Y. Chen]

Presented Thursday 10 Oct. 1415 in Track B

The BoG reviewed proposals related to the loop filter topics (CE5-related). This report includes the recommendations of the BoG for adopting or further studying of proposals.

The BoG met during the following times:

  • Tuesday Oct. 8: 9:00-13:00, 14:30-21:00
  • Wednesday Oct. 9: 11:00-13:30, 15:00-20:10
  • Thursday Oct. 10: 9:00-12:30

Recommendations of BoG:

Deblocking filter

It is recommended to adopt proposal JVET-P0043 (the specification text). The software attached to the proposal needs to be fixed.

Decision: Adopt JVET-P0043. This is correcting some inconsistency of deblocking in case of affine 4x4 and TPM block edges, when they coincide with TU boundary. Text was confirmed to be appropriate, aligned software still needs to be uploaded.

It is suggested to study proposal 1 of JVET-P0161 (and similar proposals, see under notes of JVET-P0161) in the CE. This would be either or two test cases (depending if proponents of JVET-P0586 decided to join the other test or have a separate test).

In track A, it is discussed that this would require storing information about presence of weighted prediction and imposing them in the decision of deblocking.

Also test JVET-P0269 method 1 in CE.

Test in the CE of JVET-P0441 (where subjective improvements are expected). This would change some conditions to not apply deblocking at affine inner boundaries unless these are at TU boundaries. This requires one more condition check, so it is not a simplification.

Test JVET-P0411...

Adopt JVET-P0505
It was reminded that in cases where the JVET document is also made available as MPEG output document, a separate version under the MPEG document header should be generated. This version should be sent to GJS and JRO for upload.
