1. A method for decoding a video signal by a decoding apparatus, the method comprising:
obtaining prediction mode information of a current block from the video signal, the prediction mode information indicating whether the current block is coded using inter prediction or intra prediction; and
decoding the current block using the intra prediction in case the prediction mode information indicates that the current block is coded using the intra prediction,
wherein the decoding the current block comprises:
determining an intra luma prediction mode for a luma sample of the current block;
obtaining intra chroma prediction mode information for the current block from the video signal; and
determining an intra chroma prediction mode for a chroma sample of the current block from a mapping table using the intra luma prediction mode and the intra chroma prediction mode information,
wherein in case the intra chroma prediction mode information has a specific value, the intra chroma prediction mode is set to be the same as the intra luma prediction mode in the mapping table, and
wherein the mapping table includes values representing a DC prediction mode and an angular prediction mode.
