An interframe prediction processor designed for high-speed video coding and decoding. The interframe prediction processor has an address selector and a predictor calculator. The address selector receives information about MBAFF type and coding type. When performing motion compensation for a given MBAFF picture with reference to blocks surrounding a current block, the address selector provides memory addresses of reference motion vectors according to the coding type of the current block pair, as well as to the coding type of the reference blocks. The predictor calculator that determines a motion vector predictor for each constituent block of the current block pair based on reference motion vectors read out of the provided memory addresses.
