18th Meeting: Teleconference, April 2020 2020-04-20 14:59
AHG2: Editorial input of integrated text for HLS adoptions
Authors: Ye-Kui Wang ByteDance Rickard Sjöberg Ericsson
Abstract
This document is Draft 8 of a new ITU-T Recommendation and ISO/IEC International Standard entitled Versatile Video Coding. It has been developed by a joint collaborative team of ITU-T and ISO/IEC experts known as the Joint Video Experts Team (JVET), which is a partnership of ITU-T Study Group 16 Question 6 (known as VCEG) and ISO/IEC JTC 1/SC 29/WG 11 (known as MPEG). This draft new standard has been designed with two primary goals. The first of these is to specify a video coding technology with a compression capability that is substantially beyond that of the prior generations of such standards, and the second is for this technology to be highly versatile for effective use in a broadened range of applications. Some key application areas for the use of this standard particularly include ultra-high-definition video (e.g., with 3840×2160 or 7620×4320 picture resolution and bit depth of 10 or 12 bits as specified in Rec. ITU-R BT.2100), video with a high dynamic range and wide colour gamut (e.g., with the perceptual quantization or hybrid log-gamma transfer characteristics specified in Rec. ITU-R BT.2100), and video for immersive media applications such as 360° omnidirectional video projected using a common projection format such as the equirectangular or cubemap projection format, in addition to the applications that have commonly been addressed by prior video coding standards.
Meeting Notes
JVET-R0481 AHG2: Editorial input of integrated text for HLS adoptions [Y.-K. Wang (Bytedance), R. Sjöberg (Ericsson)] [late]

This was reviewed in the closing plenary of Friday 24 April at 1500 (chaired by GJS & JRO) and confirmed to appear to represent the actions of the meeting.

The integration of JVET-R0410 item 10 was suggested to potentially need some refinement.

Using the bug tracker was suggested for any issues noticed in the interpretation of recorded actions.

It was remarked that there is an issue in the conditions for signalling the mvd_l1_zero_flag in the document relative to JVET-R0324. It was agreed to resolve the question after the meeting. See the post-meeting note on this subject in the discussion of JVET-R0410.

Review of editors’ notes in texts:
  • Decision (cleanup): Allow the value 6 for chroma sample location type indicators when present.
  • Decision (cleanup): Add a byte to the decoded picture hash SEI message with a single_component_flag followed by 7 reserved zero bits. The width and height of each component are defined externally.
  • For the decoded picture hash, the two’s complement issue is also found in HEVC. This should be further studied.
  • Decision (cleanup): When used with a RWP SEI message, the generalized cubemap message shall have the same functionality as the “traditional” cubemap message (define by syntax element constraints)
  • Decision (cleanup): (pt_)display_elemental_periods_minus1: specify as u(4).

JVET AHG report: Test model software development (AHG3)
Authors: F. Bossen Xinwei Li Karsten Sühring Karl Sharman Vadim Seregin Alexis Tourapis Jens-Rainer Ohm
Abstract
This report summarizes the activities of the AhG3 on Test model software development that has taken place between the 20th and 21st JVET meetings.
Meeting Notes
JVET-U0003 JVET AHG report: Test model software development (AHG3) [F. Bossen, X. Li, K. Sühring, K. Sharman, V. Seregin, A. Tourapis]

The mandates given to the AHG were:

  • Coordinate development of test model (VTM, HM, SCM, SHM, HTM, MFC, MFCD, JM, JSVM, JMVM, 3DV-ATM, and HDRTools) software and associated configuration files.
  • Produce documentation of software usage for distribution with the software.
  • Enable software support for recently standardized additional SEI messages.
  • Discuss and make recommendations on the software development process.
  • Propose improvements to the guideline document for developments of the test model software.
  • Perform tests of test model behaviour using common test conditions.
  • Suggest configuration files for additional testing of tools.
  • Investigate how to minimize the number of separate codebases maintained for group reference software.
  • Coordinate with AHG on Draft text and test model algorithm description editing (AHG2) to identify any mismatches between software and text, and make further updates and cleanups to the software as appropriate.
  • Coordinate with AHG6 for integration with 360lib software.

The software model versions prior to the start of the meeting were:

  • VTM 11.0 (Nov. 2020)
  • HM-16.22 (Jul. 2020)
  • HM-16.21+SCM-8.8 (Mar. 2020)
  • SHM 12.4 (Jan. 2018) [svn]
  • HTM 16.3 (Jul. 2018) [svn]
  • JM 19.0
  • JSVM 9.19.15
  • JMVC 8.5
  • 3DV ATM 15.0 (no version history)
  • HDRTools 0.19.1 (Sep. 2019)

Software for MFC and MFCD is only available in the version published by ITU-T and ISO/IEC. It is planned to create repositories with the latest versions available in ITU-T H.264.2 (02/2016)....

Summary information on BD-rate experiment evaluation practices
Authors: K. Andersson F. Bossen Jens-Rainer Ohm Andrew Segall Rickard Sjöberg J. Ström Gary J. Sullivan Alexis Tourapis
Abstract
This document provides general summary information about typical quality measurement practices for video coding experiments in recent work in MPEG and VCEG and their JVET and JCT-VC joint teams. In particular, it describes the use of Bjøntegaard Delta rate (BD-rate) measurements. It aims at providing a concept-level overview of recent practices and to provide some references to technical papers that describe further details. It provides comments on why some of the choices were made and points at situations where caution must be taken when interpreting the results. Revision marks are shown relative to the January 2020 output document, JVET-Q2016-v4.
Meeting Notes
JVET-R2016 Summary information on BD-rate experiment evaluation practices [K. Andersson, F. Bossen, J.-R. Ohm, A. Segall, R. Sjöberg, J. Ström, G. J. Sullivan, A. Tourapis] (2020-05-15)

Minor refinements of the description were planned.

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 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:

  • Mon. 22 June – Wed. 1 July 2020, 19th meeting under ITU-T auspices conducted by teleconference.
  • Wed. 7 – Fri. 16 October 2020, 20th meeting under WG 11 auspices in Rennes, FR.
