Title:

METHOD FOR GENERATING MODE LIST FOR MULTI-LINE INTRA PREDICTION, AND DEVICE THEREFOR AND COMPUTER PROGRAM

Document Type and Number:

Japanese Patent JP2022177230

Kind Code:

A

Abstract:

To provide a method for signaling an intra prediction mode used for encoding a current block.SOLUTION: A method includes: generating a first MPM list corresponding to a zero reference line of a current block and including a first plurality of intra prediction modes; generating a second MPM list corresponding to one or more non-zero reference lines of the current block and including a second plurality of intra prediction modes, generating the second MPM list in which the second plurality of intra prediction modes include a subset of the first plurality of intra prediction modes; signaling a reference line index indicating a reference line used to encode the current block; and signaling an intra mode index indicating the intra prediction mode from among the first MPM list and the second MPM list.SELECTED DRAWING: Figure 8
