Title:
METHOD FOR CODING TRANSFORM COEFFICIENT AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/071832
Kind Code:
A1
Abstract:
A method by which a decoding device decodes an image, according to the present invention, comprises the steps of: receiving a bitstream including residual information; deriving a quantized transform coefficient for a current block on the basis of the residual information included in the bitstream; deriving a residual sample for the current block on the basis of the quantized transform coefficient; and generating a restored picture on the basis of the residual sample for the current block.
