Abstract
This contribution use the conventional strategy to build a 6-MPM list using five spatial neighboring blocks. However, the CABAC decoding and MPM list construction is decoupled in this contribution, thus a higher throughput CABAC decoder can be achieved. Furthermore, a macro is defined to switch on/off the alignment of RD checks with VTM 2.0.1. Experimental results of the proposed solution are as follows:

Abstract
The main goal of this Core Experiment (CE) is to study removing subjective artifacts at face boundaries, comparing 360° specific coding tools with existing coding tools, such as tiles, combined with non-normative pre- and post-processing. The tested 360° specific coding tools include modifications to in-loop filtering and inter prediction, as well as projection format adaptation. To alleviate seam artifacts, the tested solutions shall modify in-loop filters by either disabling filtering across face discontinuities and/or by using spherical neighbors in the filtering process. The tested solutions will be implemented for the hybrid equi-angular cubemap (HEC) projection and compared to two anchors. The first anchor is the 360° CTC anchor (JVET-L1012), i.e., HEC with padding of 4 samples around face row with blending (PHEC). The second anchor is the CE anchor, which is PHEC with in-loop filters disabled across face discontinuities.

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...

Abstract
This document defines common test conditions and software reference configurations to be used in the context of core experiments (CE) conducted after the 12th JVET meeting. These common test conditions are also recommended for use in technical contributions to the 13th and following JVET meetings, if applicable.

JVET-L1010 JVET common test conditions and software reference configurations for SDR video [F. Bossen, J. Boyce, X. Li, V. Seregin, K. Sühring] (2018-10-26)
For this output, it was agreed to remove discussion of BMS and to make Class F testing mandatory (but not included in the reported averages).

JVET-L0023 CE3: Summary Report on Intra Prediction and Mode Coding [G. Van der Auwera, J. Heo, A. Filippov]
This is the summary report of the third Core Experiment (CE3). The goal of CE3 is to study intra prediction tools including mode coding for the VVC standard.
The following is the list of defined sub-tests in CE3:
CE3.1: Multiple reference line prediction (9 tests)
CE3.2: Intra prediction modes (9 tests)
CE3.3: Intra reference sample interpolation (7 tests)
CE3.4: Bidirectional prediction (3 tests)
CE3.5: Cross-component prediction and separate chroma tree (18 tests)
CE3.6: Intra mode coding (7 tests)
The CE3 description originally defined 70 tests which were reduced to 53 after tests were withdrawn. This document summarizes the objective results (BD-rates, runtimes), cross-check reports and related input contributions.
