METHOD AND APPARATUS FOR INTRA PREDICTION

Document Type and Number:

WIPO Patent Application WO/2020/048463

Kind Code:

A1

Abstract:

A decoding method and a decoder for decoding a current block of a video is provided, wherein the decoding method comprises: obtaining a value of a Most Probable Modes, MPM, flag for the current block from a bitstream; obtaining an MPM index for the current block from the bitstream, when the value of the MPM flag indicates that an intra prediction mode for the current block is an intra prediction mode comprised in an MPM set of intra prediction modes; obtaining a value of an intra prediction mode for the current block, based on the MPM index and the MPM set for the current block; wherein when an intra prediction mode of a left neighboring block of the current block is a Planar mode, and an intra prediction mode of an above neighboring block of the current block is a Planar mode, the MPM set of prediction modes comprises: a Planar mode, a DC mode, a Vertical mode, a Horizontal mode, an intra prediction mode corresponding to the Vertical mode with a first offset, and an intra prediction mode corresponding to the Vertical mode with a second offset.
