Title:
AFFINE MOTION PREDICTION-BASED VIDEO DECODING METHOD AND DEVICE USING SUBBLOCK-BASED TEMPORAL MERGE CANDIDATE IN VIDEO CODING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/141879
Kind Code:
A1
Abstract:
A video decoding method performed by a decoding device according to the present document is characterized by including: a step for deriving reference subblocks in a reference picture on the basis of the motion vector of an adjacent block on the left side of the current block; a step for deriving a subblock-based temporal merge candidate for the current block on the basis of motion information about the reference subblocks; a step for forming an affine merge candidate list for the current block, the affine merge candidate list including the subblock-based temporal merge candidate; a step for deriving motion information about subblocks of the current block on the basis of the affine merge candidate list; a step for deriving prediction samples for the current block on the basis of the motion information about the subblocks; and a step for generating a reconstructed picture on the basis of the prediction samples.
