IMPROVED MOTION VECTOR TRANSMISSION APPARATUS AND METHOD USING LAYERED CODING

摘要

The present invention relates to an upper layer motion vector transmitting system using layered coding and method of transmitting the same. According to this system, a motion vector estimated in the lower layer is used to estimate a motion vector in the upper layer, thus reducing data bit rate required for transmission of motion vector to the upper layer. This system includes an upper layer motion vector estimating part estimating a motion vector of the upper layer by inputting an estimated motion vector of the lower layer
