Abstract: Disclosed herein are an apparatus and a method of providing recompression of a video capable of recompressing and transmitting flags of data having an association with neighboring data in a video block and an original video by a simple logic. To this end, the apparatus of providing recompression of a video includes: a recompressing unit recompressing a compressed video frame based on information obtained by comparing a selected block selected from the compressed video frame and an adjacent block adjacent to the selected block with each other; and a frame memory controlling unit storing the recompressed video frame in a frame memory. Therefore, a hardware volume may be decreased while original video data are maintained.

Abstract: A motion estimation apparatus and method are disclosed. The motion estimation apparatus includes processing element (PE) array units, sub-SAD calculation units, motion vector calculation units, and a minimum motion vector selector. The PE array units each perform parallel processing for each of the three types of coding units. The sub-SAD calculation units calculate respective SAD values for the three types of coding units. The motion vector calculation units calculate respective motion vectors for the three types of coding units. The minimum motion vector selector selects a minimum motion vector from among the motion vectors.
