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.

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.

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.
- Wed. 6 – Fri. 15 January 2021, 21st meeting under WG 11 auspices in Capetown, ZA.
- Tue. 20 – Wed. 28 April 2021, 22nd meeting under ITU-T auspices in Geneva, CH.
The agreed document deadline for the 19th JVET meeting was planned to be Wednesday 10 June 2020 (earlier than usual).
Vittorio Baroncini, Andrew Segall, Mathias Wien, and Yan Ye were thanked for their efforts in further...

Approximately 227 people attended the AHG pre-meeting, and approximately 45 input documents were discussed.
The following recommendations were made to the JVET:

Abstract
It is asserted that, in VTM-8.0, if slice_ts_residual_coding_disabled_flag == 1, the encoder RDOQ process does not select proper residual coding method for transform skip (TS) and BDPCM blocks. In this contribution, the encoder RDOQ process is modified so that it can select correct residual coding method during RDOQ process.

JVET-R0116 AHG11/AHG14: On sign data hiding of transform skip block [M. G. Sarwer, Y. Ye, J. Luo (Alibaba)]
It is asserted that, in VTM-8.0, if slice_ts_residual_coding_disabled_flag == 1, the encoder RDOQ process does not select proper residual coding method for transform skip (TS) and BDPCM blocks. In this contribution, the encoder RDOQ process is modified so that it can select correct residual coding method during RDOQ process.
It is further reported that, in VTM-8.0 software, an encoder-decoder mismatch is also observed if both slice_ts_residual_coding_disabled_flag == 1 and pic_sign_data_hiding_enabled_flag == 1. This contribution also proposes two methods to resolve the encoder-decoder mismatch issue. In the first method, sign data hiding (SDH) is disabled for BDPCM blocks only, whereas in the second method, SDH is disabled for both TS and BDPCM blocks. The encoder RDOQ bug fix (me...

JVET-R0011 JVET AHG report: Screen content coding (AHG11) [S. Liu, J. Boyce, A. Filippov, Y.-C. Sun, J. Xu]
This document summarizes the activity of AHG11: Screen Content Coding between the 17th Meeting in Brussels, BE (7–17 January 2020) and the 18th meeting by teleconference (15–24 April 2020).
The AHG used the main JVET reflector, jvet@lists.rwth-aachen.de, with [AHG11] in message headers. There were a few emails exchanged through jvet reflector, mainly for discussion of screen content test conditions in non-4:2:0 formats (as in JVET-Q2013) and the corresponding VTM software configuration setup.
In total there were noted to be 26 SCC related technical contributions identified so far, among which there were 3 IBC related technical contributions, 10 palette related technical contributions, 7 transform skip related technical contributions and 5 BDPCM related technical contributions ident...

JVET-R0016 JVET AHG report: Implementation studies (AHG16) [M. Zhou, J. An, E. Chai, K. Choi, S. Sethuraman, T. Hsieh, X. Xiu]
This document summarizes the activity of AHG16: Implementation studies, between the 17th JVET meeting in Brussels, BE (7–17 January 2020) and the 18th meeting by teleconference (15–24 April 2020).
The following three issues were suggested to need to be resolved:
The newly adopted CCALF was identified to have a line buffer issue in 4:2:2/4:4:4 coding. For 4:2:2/4:4:4 chroma format, the luma deblocking is two lines behind the chroma deblocking, but the CCALF uses the collocated luma lines (after de-blocking and SAO) for processing, resulting in the need to buffer two chroma lines for each chroma component. JVET-R0233, JVET-R0291 and JVET-R0322 were submitted to address this cost issue.
After the adoption of slice_ts_residual_coding_disabled_flag at the last meeting...
