Document Type and Number:
WIPO Patent Application WO/2020/050697
Kind Code:
A1
Abstract:
Disclosed according to the present invention are a method of decoding a video signal and a device therefor. Specifically, a method of decoding an image on the basis of an intra-prediction mode may comprise the steps of: acquiring a most probable mode (MPM) flag indicating whether the MPM is applied to the current block, wherein the MPM represents a mode in which an intra-prediction mode for the current block is derived from an intra-predicted block around the current block; when the MPM is applied to the current block, forming an MPM list on the basis of intra-prediction modes for neighboring blocks lying to the left of and above the current block; acquiring an MPM index indicating a particular intra-prediction mode in the MPM list; and generating a prediction block for the current block by using an intra-prediction mode specified by the MPM index.
