Abstract
Implicit transform core selection in introduced in VVC Draft 4.0. However there is no unified transform core selection method. In the contribution, two methods are proposed to addressing this problem. With all DST method to unifying ISP and shape adaptive method, -0.01%/xx%/xx% AI/RA/LDB coding gain is achieved with CTC condition (intra MTS on, inter MTS off) and -0.11%/xx%/xx% AI/RA/LDB coding gain is achieved with intra and inter MTS off condition. The ratio adaptive method achieves 0.02%/xx%/xx% AI/RA/LDB coding efficiency differencewith CTC condition and xx%/xx%/xx% AI/RA/LDB coding gain with intra and inter MTS off condition.

Abstract
In VVC Draft 4.0, two separate implicit transform selection methods based on intra mode and block-shape are introduced for ISP and implicit MTS, respectively. This joint contribution describes the unified design adopted in the 14th JVET meeting, where the components of the unified design are independently proposed and tested in JVET-N0172, JVET-N0375, JVET-N0419 and JVET-N0420:

JVET-N0866 Non-CE6: Combined Test of JVET-N0172/JVET-N0375/JVET-N0419/JVET-N0420 on Unification of Implicit Transform Selection [H. Gao, S. Esenlik, B. Wang, A. M. Kotra, J. Chen (Huawei), H. E.

In VVC Draft 4.0, two separate implicit transform selection methods based on intra mode and block-shape are introduced for ISP and implicit MTS, respectively. This joint contribution describes the unified design adopted in the 14th JVET meeting, where the components of the unified design are independently proposed and tested in JVET-N0172, JVET-N0375, JVET-N0419 and JVET-N0420:
- The implicit MTS part of the adoption is proposed and tested in JVET-N0172 and JVET-N0419.
- The transform derivation for ISP is proposed and tested in JVET-N0172, JVET-N0375 and JVET-N0420.
The adopted unified method provides -0.01%, 0.00%, and -0.01% coding efficiency over VTM4.0 for AI, RA, and LDB cases under CTC, respectively. As compared to the current implicit MTS design in VTM-4.0, -0.11%, -0.02%, and 0.02% are achieved for AI, RA, and LDB cases, respectively.

Abstract
This document provides description for core experiment 11 (CE11). The objective of CE11 is to investigate the various methods for supporting gradual random access (GRA) in VVC and implementation of those methods on top of VTM reference software.

JVET-N1031 Description of Core Experiment 11 (CE11): Gradual random access [K. Kazui, J.-M. Thiesse, Hendry, K. Kawamura]
New – the previous CE11 was subsumed under CE5.
The previous CE12 (Tile set boundary MC handling) was discontinued as per discussion on HLS topics.
It was emphasized that those CEs which plan subjective testing to study JVET-N0835 which points to some issues of selecting the test conditions for that.
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 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 (starting meetings on the Wednesday prior to su...
