1. A method for decoding a video signal, comprising:
inducing a chroma intra prediction mode applied to a current chroma block based on a luma intra prediction mode of a luma block corresponding to the current chroma block;
generating a chroma prediction sample of the current chroma block based on the chroma intra prediction mode; and
restoring the current chroma block based on the chroma prediction sample,
wherein the chroma intra prediction mode applied to the current chroma block is induced based on a preset specific luma intra prediction mode when a matrix-based intra prediction (MIP) mode is applied to the luma block corresponding to the current chroma block.
