Title:
マルチラインイントラ予測のためのモードリストを生成する方法、並びにその装置及びコンピュータプログラム
Document Type and Number:
Japanese Patent JP7259013
Kind Code:
B2
Abstract:
A method of signaling an intra prediction mode used to encode a current block in an encoded video bitstream includes generating a first most probable mode (MPM) list corresponding to a zero reference line of the current block, wherein the first MPM list includes 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, wherein the second MPM list includes 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.
