Claim 8:
9. A method of video decoding performed in a video decoder, the method comprising:
receiving coded information of a current block and neighboring blocks of the current block from a coded video bitstream;
decoding 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; and
in response to the first information indicating that the current block is intra predicted based on the DIMD,
decoding second information associated with the current block in the coded information, the second information indicating whether the current block is partitioned based on an intra sub-partition (ISP) mode;
decoding a syntax element associated with the ISP mode in response to the second information indicating that the current block is partitioned based on the ISP mode; and
in response to the second information indicating that the current block is not partitioned based on the ISP mode, determining a first intra prediction mode based on the DIMD, and determining a second intra prediction mode based on a syntax element that is included in the coded information and associated with most probable mode (MPM) and MPM remainder.
