When a reverse reproduction is instructed, B pictures and P pictures in an MPEG video stream are once decoded and are again recoded into B pictures by an MPEG video encoder. Combined with I picture in the MPEG video stream, thereafter, a recoded data sequence comprised of I pictures and B pictures is generated, so as to be overwritten in a storage area of a hard disk. An MPEG video decoder reads out this recoded data sequence in a reverse time-series manner, and decodes this successively and outputs it to a display circuit.
