Abstract:
Method and apparatus for intra prediction mode coding and decoding are disclosed. In one embodiment, the encoding and decoding process assigns individual indices and codewords to DC mode and Planar mode respectively. The flag is set if the current intra prediction mode is equal to any of one or more neighboring intra prediction modes. Variable length codes are designed for a remaining mode set. If the flag is not set, the currently intra prediction mode is encoded using the variable length codes. In another embodiment, multiple most probable modes are used. If the current intra prediction mode is not equal to any of the multiple most probable modes, the current intra prediction mode is encoded using variable length codes designed for the corresponding remaining modes according the ranking order of the remaining modes

Claim (Index 4):
An apparatus of decoding a block, the apparatus comprising:\n a processor configured to execute executable code to cause the processor to:\n receive a flag indicating whether a current intra prediction mode is equal to one or more most probable modes; \n derive, based on a value of the flag, the current intra prediction mode from a decoded mode index; and \n decode the block according to the current intra prediction mode identified by the decoded mode index, \n wherein the current intra prediction mode belongs to a mode set that comprises a DC mode, a Planar mode, and at least one directional mode, each mode of the mode set being represented by a different mode index value, the processor is configured to:\n when the decoded mode index corresponds to a first mode index value that represents the Planar mode, derive the current intra prediction mode to be the Planar mode; and \n when the decoded mode index corresponds to a second mode index value that represents the DC mode, derive the current intra prediction mode to be the DC mode, \n the first mode index value is first in a predetermined order among mode index values of modes of the mode set, and is succeeded by the second mode index value.
