Claim 14:
15. A non-transitory computer-readable storage medium storing instructions that cause at least one processor to:
receive video data including a source video sequence; and
encode pictures of the source video sequence into a coded video sequence by performing:
setting a first flag indicating whether an intra prediction mode corresponding to a current block is a directional mode; and
based on the first flag indicating that the intra prediction mode corresponding to the current block is the directional mode, setting a second flag indicating whether the intra prediction mode is a decoder side intra mode derivation (DIMD) mode; and
based on the second flag not indicating that the intra prediction mode is the DIMD mode:
setting a third flag indicating an index of the intra prediction mode in an allowed intra prediction modes (AIPM) list; and
performing the intra prediction of the current block, using the intra prediction mode corresponding to the third flag.
