Abstract

PURPOSE:To increase the efficiency of coding, by arranging the level in the order of probability for the video signal inputted next based on the video signal already inputted and detecting the order on this level taken by actual video signals. CONSTITUTION:The prediction circuit 2 inputs the multi-video signal 1 to predict the video signal input at present based on the video signal already inputted and the prediction error signal is fed to the coding circuit 4. The coding circuit 4 codes the prediction error signal 3 and outputs it as the coding signal 5. In the prediction circuit 2, based on the video signal inputted, the levels are arranged in the order from higher level of the probability taken by the video signal inputted next, and the order in which the order of levels arranged is in agreement with the video signal inputted actually is detected and it is converted to the signal 3. Thus, the rate of agreement is increased by the linear programming method, allowing to increase the efficiency of coding.
