Claim 6:
7. A method for encoding a video signal, the method comprising:
determining reference sample line being used for the intra prediction;
generating reference sample line information of a current block, wherein reference sample line information represents an index indicating reference sample line being used for the intra prediction;
determining an intra prediction mode of the current block;
generating intra prediction information based on the intra prediction mode;
generating an intra sub-partition(ISP) flag representing whether the current block is partitioned into sub-partitions based on the reference sample line information;
generating prediction samples of the current block based on the intra prediction mode and reference samples;
generating residual samples of the current block based on the prediction samples; and
performing a transform, quantization and entropy-encoding the residual samples,
wherein the intra prediction information includes a first flag representing whether the intra prediction mode is not a planar mode, and
wherein the first flag is coded with 0 based on the intra prediction mode corresponds to the planar mode and coded with 1 based on the intra prediction mode corresponds to one of modes other than the planar mode.
