Motion compensated predictive encoding and decoding system
专利汇可以提供Motion compensated predictive encoding and decoding system专利检索，专利查询，专利分析的服务。并且PURPOSE:To improve the resolution of a moving vector by obtaining not only an inter-frame moving vector but also the moving vector for the unit of M frame and executing motion compensation by an estimated value from these vectors. CONSTITUTION:The first frame is read from a frame memory FM 1 through a selector SEL 2 and the decoded picture of the 0-th frame is read from a decoded picture frame memory DFM. Then, the pictures are respectively supplied to a motion compensation circuit MCO. The detection of a moving vector MVO is executed in the circuit MCO and the vector is supplied to a moving vector decision circuit SEL-MV. A residual moving vector MVe corresponding to the vector MVO is inputted from a buffer BMVe for residual moving vector to a division and subtraction circuit CAL-MVei. At such a time, when a scene change is not detected, the vector is remained from a residual frame counter FMCNT to the circuit CAL-MVei and a frame count is supplied. An estimated moving vector MVei is supplied from the circuit CAL-MVei to a moving vector select circuit SEL-MV.，下面是Motion compensated predictive encoding and decoding system专利的具体信息内容。
