Classification: CPC H | IPC H

Claim 12:
13. An apparatus, comprising:
processing circuitry configured to:
receive coded information of a current block and neighboring blocks of the current block from a coded video bitstream;
obtain first information associated with the current block in the coded information, the first information indicating whether the current block is intra predicted based on decoder side intra mode derivation (DIMD) in which an intra prediction mode of the current block is derived based on the neighboring blocks;
obtain second information associated with the current block and the neighboring blocks in the coded information, the second information indicating whether the current block and one or more of the neighboring blocks are partitioned based on an intra sub-partition (ISP) mode;
set a context model index to a first value in response to (i) the first information indicating that the current block is intra predicted based on the DIMD, and (ii) the second information indicating that an above adjacent block or a left adjacent block of the current block in the neighboring blocks is partitioned based on the ISP mode; and
decode the current block from the coded video bitstream based at least on the context model index.
