Claim:
1. A moving image decoding apparatus which performs motion-compensation decoding involving motion compensation of a stream of motion-compensation coded moving images, said moving image decoding apparatus comprising: a decoding unit configured to decode, from the stream, identification information identifying at least one motion compensation filter coefficient among a plurality of motion compensation filter coefficients, the at least one motion compensation filter coefficient being required for the motion compensation; a memory for holding the motion compensation filter coefficients for use in the motion compensation of the stream; a storage unit configured to hold at least one motion compensation filter coefficient among the motion compensation filter coefficients held in said memory, the at least one motion compensation filter coefficient being required for the motion compensation; a motion compensation unit configured to perform the motion-compensation decoding using the at least one motion compensation filter coefficient which is held in said storage unit and identified based on the identification information; and a transfer control unit configured to transfer the at least one motion compensation filter coefficient identified based on the identification information from said memory to said storage unit.
