ABSTRACT:
A motion-vector operation device includes an upper memory composed of first and second banks that store motion vectors of a lower block group belonging to a macroblock, a left memory storing motion vectors of a right block group belonging to a macroblock, and an estimator predicting a motion vector of a current block with reference to the motion vectors stored in the first and second banks of the upper memory and the left memory in accordance with an operation mode and a position of the current block in a super macroblock.
