摘要： A method and apparatus for video motion compensation, power of two reduction and color format conversion is disclosed. The motion compensation engine performs the MPEG-2 functions of half pel compensation, inverse discrete cosine transform and merge. Dual prime, field-based and frame-based macroblocks are supported. Data reduction may be performed in the vertical direction, the horizontal direction, or both.
