DEVICE AND METHOD FOR DECODING MOVING PICTURE

摘要

PROBLEM TO BE SOLVED: To provide a device of high error resistance by inputting a code string where information showing the prediction mode of the highest significance and information of comparatively lower significance are arranged in the order of significance among information on the prediction of a plurality of divided blocks and multiplexing them, decoding the string and reproducing an original moving picture signal. SOLUTION: A code string where information showing the prediction mode of the highest significance and information whose significance is comparatively low are arranged in the order of significance among information on the prediction of a plurality of divided blocks and multiplexed is inputted. The string is decoded and an original moving picture signal is reproduced. In the device, information showing the prediction mode of the highest significance (mode information) is inputted after the picture header of the higher hierarchy code string. That is, the code string of prediction mode information among the code strings obtained by encoding large area prediction mode/moving vector information 116 and small area prediction mode information 117, which are outputted from a prediction circuit 102, by a variable length encoding circuit 118 is inputted after the header.
