METHOD AND APPARATUS FOR DC INTRA PREDICTION MODE FOR VIDEO ENCODING AND DECODING

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for a DC intra prediction mode for video encoding and decoding.SOLUTION: 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. At least a portion is encoded using the direct current intra prediction mode.
