ABSTRACT:
An apparatus is for compressing a motion picture signal. The apparatus includes a motion detection block; a difference determination block; an orthogonal transform block; a quantizing block; a local decoding block; a motion vector encoding block; and a motion compensating block. Significantly, the motion vector encoding block operates when respective differences between the motion vector for the target block and each motion vector for the comparison blocks is outside an allowable range. The motion vector encoding block generates an encoding of the motion vector for the target block which represents the motion vector for the target block as a difference between the motion vector for the target block and the motion vector for a selected one of the comparison blocks.
