IMAGE DECODING METHOD FOR RESIDUAL CODING IN IMAGE CODING SYSTEM, AND APPARATUS THEREFOR

Abstract: an image decoding method performed by a decoding apparatus, according to the present document, comprises the steps of: obtaining a dependent quantization available flag; obtaining a tsrc available flag, on the basis of the dependent quantization available flag; determining a residual coding syntax for a current block, on the basis of the tsrc available flag; obtaining residual information of the determined residual coding syntax for the current block; deriving a residual sample of the current block, on the basis of the residual information; and generating a reconstructed picture, on the basis of the residual sample, wherein the dependent quantization available flag is a flag regarding whether dependent quantization is available, the tsrc available flag is a flag regarding whether tsrc is available, and the tsrc available flag is obtained on the basis of the dependent quantization available flag having a value of 0.
