Abstract
A method of video decoding at a video decoder can include partitioning a coding tree block (CTB) into coding blocks, determining whether an intra sub-partition (ISP) mode is allowable for a current block based on a first block size of the current block that is one of the coding blocks, and decoding the current block according to the ISP mode when the ISP mode is allowed for the current block.
Claims20
A method of video decoding at a video decoder, comprising:
- partitioning a coding tree block (CTB) into coding blocks;
- determining whether an intra sub-partition (ISP) mode is allowable for a current block based on a first block size of the current block that is one of the coding blocks;
- and
- when the ISP mode is allowed for the current block, decoding the current block according to the ISP mode.
An apparatus of video decoding, comprising circuitry configured to:
- partition a coding tree block (CTB) into coding blocks;
- determine whether an intra sub-partition (ISP) mode is allowable for a current block based on a block size of the current block that is one of the coding blocks;
- and
- when the ISP mode is allowed for the current block, decode the current block according to the ISP mode.
A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform a method of video decoding, the method comprising:
- partitioning a coding tree block (CTB) into coding blocks;
- determining whether an intra sub-partition (ISP) mode is allowable for a current block based on a block size of the current block that is one of the coding blocks;
- and
- when the ISP mode is allowed for the current block, decoding the current block according to the ISP mode.
