Abstract
A compressed motion video code processing circuit and a compressed motion video code processing method are disclaused. The processor decodes a bitstream into a moving picture data sequence and outputts each picture to an outside circuit (e.g., a monitor circuit) according to the original video sequence. That is, the bitstream includes I-pictures, P-pictures and B-pictures, and each pictures are arranged according to a different rule from the original video sequence. When an error is caused in the bitstream, the data of the error portion is replaced by decoded data of corresponding portion in a correction picture which has been decoded and stored. The correction picture is selected, for example, as a picture which has short inter-frame distance from a current picture under decoding.
