Claim 0:
1. A video decoding apparatus for reconstructing a chroma block of a target block to be reconstructed, the video decoding apparatus comprising:
a decoder configured to decode correlation information between first residual samples and second residual samples, the first residual samples, 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;
a predictor configured to generate predicted samples of the first chroma component and predicted samples of the second chroma information on the basis of the prediction information;
a chroma component reconstruction unit configured to derive the second residual samples by applying the correlation information to the first residual samples; and
an adder configured to reconstruct a chroma block of the first chroma component by adding the first residual samples and the predicted samples of the first chroma component and configured to reconstruct a chroma block of the second chroma component by adding the second residual samples and predicted samples of the second chroma component.
