A method of intra prediction comprising computing a prediction block for a luma block, wherein computing the prediction block includes using a plurality of directional intra prediction modes and an angular table (angTable) comprising a plurality of entries, and wherein a value of each entry is determined via a mathematical derivation. An apparatus comprising a memory configured to store an angTable comprising a plurality of entries, wherein a value of each entry is determined via a mathematical derivation, and a processor configured to compute a prediction block for a luma block using a plurality of directional intra prediction modes and the angTable. |
