A method and apparatus for improving intra prediction table new angle

Intra prediction, the method comprising calculating the luminance block prediction block, wherein the calculating includes using a plurality of directional prediction block intra prediction modes using the angle and the table (the angTable) comprises a plurality of entries, and wherein each value of the entry is determined by mathematical derivation. Species, the apparatus comprising: a memory for storing a plurality of entries of the angTable, wherein the value of each entry is determined by mathematical derivation; and a processor for using a plurality of directional intra prediction mode, and calculating the predicted block luminance angTable block.
