JVET-K0294 Tencent test sequences, and Class F test set restructure [J. Ye, S. Wenger, X. Li, S. Liu, L. Wu, C. Xie, K. Liu, B. Wang, P. Liu, K. Dong, Y. Kuang, W. Feng (Tencent)]

Four test sequences were presented to JVET for proposed inclusion into coding experiment test sets. All are in 1080p YUV 4:2:0 resolution. Three of the four sequences were captured screen content of eSport/gaming applications and were suggested to be appropriate for the Class F test set. One sequence is part of a music video and was offered for the class B test set. Objective and subjective test results were provided for all sequences. The copyright holder offered the sequences under a copyright license claimed to be suitable for use in standardization projects.

The proponents asserted that the current Class F test set is outdated and does not reflect today’s screen content, both in resolution and frame rate. It was also proposed to replace the current Class F sequences with those of the SCC 4:2:0 TGM test set. The proponents further asserted that eSport/gaming content is currently underrepresented. It was proposed to include one eSport/gaming sequence into the Class F test set, either by adding or by replacing one of the SCC4:2:0 TGM sequences with the new material.

This contribution was discussed in the CTC BoG (see the notes for JVET-K0541).

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 or Wednesday of the first week and closing it on the Tuesday or Wednesday of the second week of the SG 16 meeting – a total of 6–7.5 meeting days), and
• Otherwise meeting under ISO/IEC JTC 1/SC 29/WG 11 auspices when it meets (starting meetings on the Wednesday or Thursday prior to such meetings and closing it on the last day of the WG 11 meeting – a total of 8.5 meeting days).

In cases where 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:

• Wed. 3 – Fri. 12 Oct. 2018, 12^th meeting under WG 11 auspices in Macao, CN.
• Wed. 9 – Fri. 18 January 2019, 13^th meeting under WG11 auspices in Marrakesh, MA.
• 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 WG11 auspices in Gothenburg, SE.

The agreed document deadline for the 12^th JVET meeting was agreed to be Monday 24 September...

JVET-K0541 BoG report on common test conditions [J. Boyce]

This BoG met on 14 July 2018 (chaired by J. Boyce) to discuss forming recommendations about modifying the Class F sequences in the Common Test Conditions (CTC). The BoG had planned to meet again after some off-line work, but instead the further discussion took place directly in the JVET plenary.

Three eSports sequences were provided in JVET-K0294, all from the same video game. All of the sequences were somewhat similar. The first sequence, Tencent_AOV5 had the highest bit rate, and had some global motion. There was agreement in the BoG that it would be desirable to select one of the sequences to include in the new Class F, with a preference for the Tencent_AOV5 sequence.

An additional concert sequence provided with JVET-K0294 was viewed, but was not relevant for Class F.

The existing Class F sequences and the SCC Class TGM 4:2:0 sequences were viewed. The group expressed interest in replacing most of the sequences. Of the existing Class F sequences, SlideShow was considered the best. It is 720p resolution.

Several sequences from Twitch (no contribution uploaded yet) were informally viewed. All were 1080p60 4:2:0 and were eSports/video gaming content. It was verbally indicated that these sequences could be made available to the group.

The Twitch sequences have a lot of scene changes, but some sequences have reasonably long segments without scene changes, greater than 10 seconds. The sequences of most interest were called EuroTrucking (10 seconds near the end), and Witchers (early in the sequence).

It was suggested in the...
