Abstract

PURPOSE:To reduce the necessary amount of operation by carrying out the detection of the dynamic vector in multiple steps. CONSTITUTION:The evaluating function is obtained at the 1st step for the 1st shift vector group which is displayed in A, B, C, D and E each, and then the shift vector featuring the minimum evaluating function is obtained among those in the vector group. Here if D is the vector to be obtained, the evaluating function value is obtained in the same way at the 2nd step for 2nd shift vector groups D1-D9 which are distributed near D. And then the shift vector featuring minimum evaluating function is obtained among the 2nd shift vector groups. And if D9 is minimum, the evaluating value is obtained at the 3rd step for 3rd shift vector groups D9.1- D9.9 which are distributed near D9. Then the shift vector featuring the minimum evaluating function is obtained. And if D9.5 features the minimum value, D9.9 is decided as the dynamic vector to the block. In this case, the signal of the preceding frame is shifted by vector D9.5 to be used as the predicting signal. Thus the differential signal of this predicting signal and the present-frame signal plus shift vector D9.5 are coded in the form of the dynamic vector to be transmitted.
