Title:

METHOD OF MODE LIST GENERATION FOR MULTI-LINE INTRA PREDICTION, APPARATUS THEREFOR, AND COMPUTER PROGRAM

Document Type and Number:

Japanese Patent JP2023126585

Kind Code:

A

Abstract:

To provide a method of signaling an intra prediction mode used to encode a current block.SOLUTION: A method includes: generating a first most probable mode (MPM) list corresponding to a zero reference line of a current block, the first MPM list 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, the second MPM list including a second plurality of intra prediction modes, the second plurality of intra prediction modes including 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
