PROBLEM TO BE SOLVED: To suppress power consumption when receiving warning information during a stand-by state. SOLUTION: In ISDB-T standard, earthquake motion warning information is transmitted by an AC (auxiliary channel) signal. In a stand-by state, a receiving part 12 selects only one segment of No.0 out of thirteen segments regulated by the ISDB-T standard and receives the AC signal transmitted by an AC carrier of the segment of No.0. For instance, when bits from the second bit up to the fourth bit of the AC signal are received and the configuration identification of the three received bits is 001 or 110, the receiving part determines that the earthquake motion information is transmitted. Then, a quick detection flag is output from the receiving part 12 and a controller 16 receiving the quick detection flag starts processing for notifying a user of information concerned with earthquake. This invention can be applied to a receiving apparatus for receiving digital broadcasting. COPYRIGHT: (C)2011,JPO&INPIT |
