Using multiple prediction sets to encode extended unified directional intra mode numbers for robustness
An apparatus comprising a codec configured to predict an intra mode for a considered pixel block based on a plurality of coded intra modes for a plurality of adjacent pixel blocks to the considered pixel block, wherein the predicted intra mode and the coded intra modes correspond to a set of intra-frame modes that comprise a plurality of directional intra modes and at least two non-directional intra modes and that are assigned a plurality of corresponding group numbers and group index numbers, and wherein the intra mode is predicted based on the group numbers and group index numbers of the coded intra modes.
