Abstract:
A method of controlling intra prediction for decoding or encoding of a video sequence, is by at least one processor and includes obtaining an index of an intra prediction mode of a current block of the video sequence, obtaining a coefficient scanning direction based on the obtained index, using a first look up table indicating a mapping between a plurality of indices of a plurality of intra prediction modes and respective coefficient scanning directions, and performing a coefficient scanning of the current block, based on the obtained coefficient scanning direction.
