PROBLEM TO BE SOLVED: To promptly comply with the signal format change of a receiving signal in a receiver compatible with a multi-format. SOLUTION: According to detection of stream change to an invalid data stream (Ancillary No Data), a signal processing means is controlled to setting complying with the signal format of the invalid data stream (F104→F105). Namely, the setting is predictably switched to the signal format of expected forthcoming real data. When the stream change to a real data stream is actually detected, a receiving means is switched to the setting complying with the signal format of the real data stream (F107). COPYRIGHT: (C)2003,JPO
