Abstract
The invention discloses a motion vector estimation system and the method thereof for estimating an output motion vector for a macroblock of a frame. The motion vector estimation system is capable of selectively horizontally shifting a search window corresponding to each macroblock, so as to improve reusability of pixel data from previous search window and reduce memory bandwidth.
