ABSTRACT:
An encoding unit encodes and compresses picture data in a bit map format corresponding to the MPEG method. A packet assembling portion assembles the picture data encoded by the encoding unit as packets in the format corresponding to the MPEG method, and stores the packets to a storing medium. At this point, the packet assembling portion writes an I picture index to a packet that contains at least a part of I picture data. When a special reproducing operation is performed, a data storing unit reads only packets that have the I picture index. A decoding unit decodes only I picture data of picture data contained in packets read from the storing medium and displays the decoded picture data.
