JVET-L0291 CE3 Related: Extended reference sample construction for longer interpolation filter in intra prediction [S. Yoo, J. Heo, J. Choi, L. Li, J. Choi, J. Lim (LGE)]
In HEVC (and JEM), only a bi-linear interpolation filter was used for prediction of sub-pel position. However, in CE3-Intra prediction and mode coding, longer interpolation filters (i.e., 4-tap and 6-tap filters) are being considered. In the conventional way of reference sample construction, it is not available for the very-end predicted samples (some right bottom samples in a currently predicted block) to refer to the reconstructed samples in the neighbour blocks. In this contribution, an extension of a reference sample construction is proposed for longer interpolation filter. Specifically, the number of the reference samples is extended from the neighbour blocks. The experimental results are reportedly shown that 0.04% and 0.01% BD-rate coding gains from VTM-AI and VTM-RA respectively.
In RA configuration, loss (+0.17/+0.22%) is observed in chroma compared to 4-tap standalone.
No obvious benefit was seen compared to 4-tap.

JVET-L1033 Description of Core Experiment 13 (CE13): Coding tools for 360° omnidirectional video [P. Hanhart, J.-L. Lin, C. Pujara]
This CE was planned to study changes to in-loop filters, inter prediction, post-filtering, projection rotations and packings.
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. 9 – Fri. 18 January 2019, 13th meeting under WG 11 auspices in Marrakech, MA.
- Tue. 19 – Wed. 27 March 2019, 14th meeting under ITU-T auspices in Geneva, CH.
- Wed. 3 – Fri. 12 July 2019, 15th meeting under WG 11 auspices in Gothenburg, SE.
- Tue. 1 – Wed. 9 October 2019, 16th meeting under ITU-T auspices in Geneva, CH.
The agreed document deadline for the 13thJVET meeting was planned to be Wednesday 2 January 2019 (a little later than usual due to the proximity of the New Year holiday). Plans for scheduling of agenda items within that meeting...
