Title:
METHOD FOR DECODING VIDEO FOR RESIDUAL CODING AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/040410
Kind Code:
A1
Abstract:
A method for decoding a video performed by a decoding device according to the present document is characterized by comprising: a step for acquiring video information including prediction mode information and residual information through a bitstream; a step for deriving a prediction mode of a current block on the basis of the prediction mode information; a step for deriving a prediction sample on the basis of the prediction mode; a step for deriving a current residual coefficient on the basis of residual syntax elements for the current residual coefficient in the current block; a step for deriving a residual sample on the basis of the current residual coefficient; and a step for deriving a reconstructed sample of the current block on the basis of the prediction sample and the residual sample.
