Method and apparatus for video coding
Processing circuitry decodes prediction information of a block from a coded video bitstream. The block is a non-square block and the prediction information of the block is indicative of a wide angle intra prediction mode in a specific number of wide angle intra prediction modes with angles that are outside a range of directional modes from a bottom-left diagonal mode to a top-right diagonal mode for a square block. The wide angle intra prediction modes are in a first set of intra prediction modes associated with the block. The directional modes are in a second set of intra prediction modes associated with the square block. The specific number of the wide angle intra prediction modes is a function of an aspect ratio of the block. Further, the processing circuitry reconstructs at least one sample of the block according to the wide angle intra prediction mode.
