Abstract:
Methods and apparatus are provided for DC intra prediction mode for video encoding and decoding. An apparatus includes a video encoder for encoding image data for at least a portion of an input picture by deriving a direct current prediction value from a pre-determined constant and using the derived direct current prediction value for a direct current intra prediction mode. The portion is encoded using the direct current intra prediction mode.
