Abstract
PURPOSE:To achieve the forecast data compression code between screens having high compression efficiency without error, by forecasting the value of video element for the location of picture corresponded to the picture being compressed and coded, and producing the Huffman code through the check of change in the sign of positive and negative to the forecast error obtained. CONSTITUTION:From the forecast coefficient output from a forecast coefficient path 303 and the video element of reference screen from the memory 301, a video element value forecast circuit 304 of the video element location corresponding to the picture in compression code makes the forecast of video element value. Further, a coding circuit 305 checks the change in positive and negative signs to the forecast error obtained, and if no change, the absolute value of the forecast error is taken to produce the Huffman code corresponded, and if there is change, the positive and negative signs are added to the coresponding Huffman code to the absolute value of the forecast error. This output is fed to a memory 306 and it is stored with the data for one run's share of the circuit 303 and stored in a magnetic tape device 308 via an address counter 307. Thus, the forecast data compressing code having high compressing efficiency without error is obtained.
