    摘要: A method for motion vector coding of an MPEG-4 includes determining motion vector candidates, and selecting a candidate having a minimum bit rate among motion vector candidates in an encoder. A motion vector prediction error and prediction mode information and then to a decoder. The decoder estimates a minimum bit rate for coding a motion vector difference and codes a motion vector against components X and Y, using a minimum rate predictor.
