CE2-related: Bugfix for deblocking at maximum transform block boundaries
Authors: Chia-Ming Tsai MediaTek C.-W. Hsu MediaTek Y.-W. Huang MediaTek Shawmin Lei MediaTek
Abstract
In this contribution, a bugfix is proposed for deblocking at transform block (TB) boundaries. In VTM-1.0 and BMS-1.0, each coding blocks (CB) larger than maximum TB is inferred to be further partitioned into multiple TBs by tiling with the maximum TBs, while each CB smaller than or equal to maximum TB has only one TB. However, deblocking is only performed at CB boundaries and always skipped at maximum TB boundaries that do not coincide with any CB boundaries. It is proposed to apply deblocking to maximum TB boundaries that do not coincide with any CB boundaries.

JVET-K0237 CE2-related: Bugfix for deblocking at maximum transform block boundaries [C.-M. Tsai, C.-W. Hsu, Y.-W. Huang, S.-M. Lei (MediaTek)]

In this contribution, a bugfix is proposed for deblocking at transform block (TB) boundaries. In VTM-1.0 and BMS-1.0, each coding blocks (CB) larger than maximum TB is inferred to be further partitioned into multiple TBs by tiling with the maximum TBs, while each CB smaller than or equal to maximum TB has only one TB. However, deblocking is only performed at CB boundaries and always skipped at maximum TB boundaries that do not coincide with any CB boundaries. It is proposed to apply deblocking to maximum TB boundaries that do not coincide with any CB boundaries.

Decision (BF): This bugfix was adopted into the VTM (see notes under CE2)
