Abstract
A method of video decoding includes determining, for a current block of a picture, one of a plurality of reference lines. The method further includes determining an intra prediction mode for the current block in accordance with the determined one of the plurality of reference lines. The method further includes performing intra prediction for the current block based on the determined intra prediction mode and one or more samples included in the determined one of the plurality of reference lines. The plurality of reference lines includes an adjacent reference line that is adjacent to the current block and at least one non-adjacent reference line that is not adjacent to the current block, and a number of intra prediction modes associated with each of the at least one non-adjacent reference line is equal to or less than half a number of intra prediction modes associated with the adjacent reference line.
