Abstract
A method and apparatus for performing intra prediction mode partitioning predicts pixels of a video coding block using a plurality of intra prediction modes over a plurality of regions of the video coding block. Predictions can be based on reference arrays using at least one reference line above the block to be coded and/or using at least one reference column to the left of the block to be coded. Different prediction modes are used in different regions of the coding block. In at least one embodiment, the video coding block is split into a plurality of partitions in addition to having a plurality of intra prediction modes over different regions of the block. Signaling enables a decoder to determine the number of regions within a coding block. In at least another embodiment, prediction modes allowable within regions of a video coding block differ by one angular position.
