Title:
VIDEO SIGNAL PROCESSING METHOD AND APPARATUS FOR INTRA PREDICTION
Document Type and Number:
WIPO Patent Application WO/2020/171673
Kind Code:
A1
Abstract:
Embodiments of the present specification provide a video signal processing method and apparatus for intra prediction. A method for encoding a video signal, according to an embodiment of the present specification, comprises the steps of: generating a most probable mode (MPM) candidate list on the basis of a prediction mode of at least one neighboring block adjacent to a current block; changing the MPM candidate list by removing at least one mode from the MPM candidate list on the basis of an intra prediction type; determining an MPM index related to an intra prediction mode of the current block, which is derived from the MPM candidate list on the basis of a rate-distortion rate; and encoding intra prediction information including information about the MPM index and the intra prediction type. By generating the same MPM candidate list for various intra prediction types and then changing the MPM candidate list so as to remove an unavailable MPM candidate according to the intra prediction type, an encoding/decoding structure of intra prediction information can be simplified, and the data amount and computation complexity required for intra prediction can be reduced.
