    • An apparatus comprising a codec configured to predict an intra mode for a considered block based on a plurality of group numbers and a plurality of corresponding group indices for a plurality used modes of a plurality of adjacent blocks to the considered block, wherein a group number corresponding to an actual intra mode for the considered block is coded and sent if the predicted intra mode does not match the actual intra mode. Also disclosed is a network component comprising a processor configured to predict an intra mode for a considered block based on a minimum group number and a minimum group index of two used modes for two adjacent blocks of the considered block, and a transmitter configured to send coded bits of a group number for an actual intra mode for the considered block if the actual intra mode does not match the predicted intra mode.
