Abstract
Methods, apparatus, and computer readable storage medium for intra prediction mode coding in video decoding. The method includes receiving, by a device, a coded video bitstream for a block. The device includes a memory storing instructions and a processor in communication with the memory. The method also includes dividing, by the device, a list of intra modes into a plurality of intra mode sets for the block based on mode information of each intra mode in the list, the list of intra modes corresponding to an intra prediction mode of at least one neighboring block of the block; extracting, by the device from the coded video bitstream, a set index indicating an intra mode set from the plurality of intra mode sets; extracting, by the device from the coded video bitstream, a mode index indicating an intra prediction mode from the intra mode set; and determining, by the device, the intra prediction mode for the block based on the set index and the mode index.
