Abstract

See full text

If reception quality of a broadcast signal of a first frequency received by a tuner satisfies setting conditions, the frequency received by the tuner is changed from the first frequency to a second frequency. It is evaluated whether or not the amount of offset between a reference frequency and the frequency of the signal, which is generated by converting the broadcast signal of the second frequency received by the tuner into an intermediate frequency is within a predetermined range. If the offset between the reference frequency and the frequency of the intermediate frequency signal is within the predetermined range, the data included in the broadcast signal of the first frequency is acquired by a demodulating the broadcast signal of the first frequency. It is evaluated whether or not the broadcast signal of the first frequency is a broadcast signal of a broadcasting station based on the acquired data.
