Intra prediction and intra mode coding
A device includes one or more processors configured to derive M most probable modes (MPMs) for intra prediction of a block of video data. As part of deriving the M most probable modes, the one or more processors define a representative intra prediction mode for a left neighboring column and use the representative intra prediction mode for the left neighboring column as an MPM for the left neighboring column, and/or define a representative intra prediction mode for an above neighboring row and use the representative intra prediction mode for the above neighboring row as an MPM for the above neighboring row. A syntax element that indicates whether an MPM index or a non-MPM index is used to indicate a selected intra prediction mode for intra prediction of the block is decoded. The one or more processors reconstruct the block based on the selected intra prediction mode.
