Abstract
In order to play back a plurality of kinds of image data using a single device, a 1394 receiver receives data transmitted via an AV bus according to a format of an IEEE 1394 standard. A separating circuit then determines a format of this data by referring to a prescribed region of a CIP header of this data. When this data is MPEG-PS data, this data is outputted to an MPEG-PS decoder. When this data is MPEG-TS data, this data is outputted to an MPEG-TS decoder. When this data is DVCR SD data, this data is outputted to a DVCR-SD decoder. The MPEG-PS decoder, MPEG-TS decoder and the DVCR-SD decoder then decode the supplied data of respective formats.
