PROBLEM TO BE SOLVED: To provide a broadcasting receiver capable of minimizing time for analysis with analysis accuracy maintained by changing the analysis accuracy according to program types.SOLUTION: A broadcasting receiver comprises: a first receiving circuit 1 for receiving a digital audio broadcasting program; a second receiving circuit 2 for receiving an analog audio broadcasting program; a control part 3; switching means 4 for outputting an output signal of either the first receiving circuit 1 or the second receiving circuit 2; time difference analysis means 5 for analyzing a time difference in the output signal between the first receiving circuit 1 and the second receiving circuit 2; time difference control means 6 for delaying the output signal of the second receiving circuit 2 in accordance with the time difference detected by the time difference analysis means 5; and program content acquisition means 7 for acquiring program types received by the first receiving circuit 1. The time difference analysis means 5 can perform a time difference analysis with its analysis accuracy changed and the control part 3 changes the analysis accuracy of the time difference analysis means 5 in accordance with the program types received by the program content acquisition means 7. |
