Abstract: An image decoding method performed by a decoding apparatus according to the present disclosure includes receiving a bitstream including residual information; deriving quantized transform coefficients for a current block based on the residual information included in the bitstream; deriving transform coefficients for the current block from the quantized transform coefficients based on an inverse quantization process; deriving residual samples for the current block by applying inverse transform to the derived transform coefficients; and generating a reconstructed picture based on the residual samples for the current block.
