Abstract
A method for video decoding includes decoding prediction information that indicates a partition of the current block and indicates an index indicating a first intra prediction mode in a first set of intra prediction modes for a first partition of the current block. The method further includes, when the first partition has a non-square shape, remapping the first intra prediction mode to a second intra prediction mode based on an aspect ratio of the first partition. When the aspect ratio of the first partition is out of a specific range, a number of intra prediction modes in the first set of intra prediction modes that are replaced by wide-angle intra prediction modes is fixed to a pre-defined number. The method further includes decoding at least the first partition according to the first intra prediction mode or the second intra prediction mode.
