Original Abstract Submitted

A method and for reconstructing chroma blocks and a video decoding apparatus are disclosed. In accordance with one aspect of the present disclosure, provided is a method for reconstructing a chroma block of a target block to be reconstructed. The method includes decoding correlation information between first residual samples and second residual samples, the first residual sample, and prediction information of the chroma block from a bitstream, wherein the first residual samples are residual samples of a first chroma component and the second residual samples are residual samples of a second chroma component. The method further includes generating predicted samples of the first chroma component and predicted samples of the second chroma information on the basis of the prediction information, and deriving the second residual samples by applying the correlation information to the first residual samples. The method further includes reconstructing a chroma block of the first chroma component by adding the first residual samples and the predicted samples of the first chroma component and reconstructing a chroma block of the second chroma component by adding the second residual samples and predicted samples of the second chroma component.
