A half-pixel motion compensation controller accepting MPEG2 data implements a half-pixel motion compensator using a four phase division of macroblock units and a clock faster than the system clock. A FIFO controller controls the compensator. The controller includes a luminance pixel unit motion compensator, a luminance half-pixel unit motion compensator, a color motion vector converter, a color pixel unit motion compensator, a color half-pixel unit motion compensator, a luminance FIFO, a color FIFO, a luminance FIFO controller, and a color FIFO controller.
