Title:
SYSTEMS AND METHODS FOR PERFORMING INTRA PREDICTION CODING IN VIDEO CODING
Document Type and Number:
WIPO Patent Application WO/2020/184637
Kind Code:
A1
Abstract:
This disclosure relates to video coding and more particularly to techniques for intra prediction coding. In one example, a method of decoding video data, the method comprising: parsing a first syntax element having a value indicating an intra sub partitions (ISP) intra prediction is used for coding a current video block; parsing a second syntax element indicating whether a most probable mode (MPM) or a non-most probable mode (MPM) is an intra prediction mode used for generating a prediction for the current video block according to the ISP intra prediction; based on whether the second syntax element indicates the MPM or the non-MPM is an intra prediction mode used for generating a prediction, conditionally parsing one of: a third syntax element indicating the MPM, or a fourth syntax element indicating the non-MPM; and generating a prediction for the current video block based on the first syntax element.
