Claim 0:
1. A method for video decoding, comprising:
decoding prediction information of a block from a coded video bitstream, the prediction information being indicative of a reference line selected from a plurality of potential reference lines and an intra prediction mode selected from a set of potential intra prediction modes that is associated with the reference line; and
reconstructing at least one sample of the block based on the intra prediction mode and at least one reference sample in the reference line, wherein
based on the prediction information indicating a non-zero reference line, a first set of potential intra prediction modes associated with the non-zero reference line includes a smaller number of potential intra prediction modes compared to a second set of potential intra prediction modes associated with a zero reference line, and
the first set of potential intra prediction modes only includes most probable modes.
