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.

Abstract
The main goal of this Core Experiment (CE) is to investigate the performance of projection formats for 360° video coding. The tested projection formats will be compared to three anchor projection formats, namely padded equi-rectangular projection (PERP) and cubemap projection (CMP), as these formats are well-known and supported in the AVC/HEVC HLS, as well as the equi-angular cubemap projection (EAC), as several tested projection formats are variations of EAC.

JVET-E0004 JVET AHG report: Test material (AHG4) [T. Suzuki, V. Baroncini, J. Chen, J. Boyce, A. Norkin]
Discussed Thursday 12 January 1500 (GJS & JRO)
The test sequences to test as defined in JVET-D1002 were uploaded at the ftp site.
The workplan to explore characteristics of test sequences was defined as JVET-D1002. Reports of the evaluation were submitted at this meeting. Those contributions should be reviewed. Bitstreams for visual assessment were available at the ftp site prior to the meeting:
ftp.ient.rwth-aachen.de (directory /bitstreams/5_Geneva)
Volunteers were encouraged to preview those bitstreams before the meeting. It was not feasible to subjectively evaluate all bitstreams. The AHG suggested discussing how to perform visual assessment in the meeting.
The following issues were identified during the preparation of bitstreams.
Some of test sequences at the ftp site are less th...
Decisions
The AHG recommended to:
Review all related contributions.
Perform subjective viewing test as defined in JVET-D1002.
Perform viewing of new test sequences
Discuss further actions to select new test materials for JVET activity.
A BoG (coordinated by T. Suzuki) was asked to review the related contributions, and to perform pre-selection and viewing.

JVET-D0194 BoG report on test material [T. Suzuki]
The mandates of this BoG were as follows:
Review input contributions, sort out sequences which are assessed to be inappropriate for codec testing (as per assessment of the testers)
Prepare and perform visual assessment. One is HM vs JEM comparison to select test sequences and rate points for visual assessment. The other is to select 1080p test sequences
Report the results of the visual assessment
Details of the BoG report are not included here, so it should be consulted by interested parties.
10 evaluations of test material were reviewed and summarized: 6 for 4K, and 4 for 1080p. Three other contributions of new test sequences were also reviewed, including:
4K Aerial video sequences from DJI (D0060)
