MOTION VECTOR ENCODING/DECODING METHOD AND APPARATUS USING MULTIPLE MOTION VECTOR ESTIMATION AND VIDEO ENCODING/DECODING METHOD AND APPARATUS USING SAME

摘要

PURPOSE: A motion vector CODEC method used and apparatus thereof and video encoding/decoding method using that and apparatus thereof reduce the amount of bits for the coding of the motion vector. In that way the compression efficiency is improved. CONSTITUTION: MV(Motion Vector) estimation units(410, 420) presume a plurality of motion vectors. The motion vector estimating unit presumes one motion vector among a plurality of motion vectors as the motion vector of the current block. The motion vector estimating unit presumes the rest motion vector among a plurality of motion vectors according to one or more estimation standards defining the image decoder device and radical. A MV encoding unit(430) encodes the motion information which becomes as described above.
