PROBLEM TO BE SOLVED: To provide a receiver unit capable of receiving a broadcast channel by appropriately setting conditions for achieving the efficient acquisition of signals without specially providing a bandpass filter for detecting an interference signal. SOLUTION: When the receiver unit is instructed to receive a specified channel, a control section instructs to receive the channel of a lower band neighboring station (S22). When it is decided that the lower band neighboring station exists, the selection of a narrowband filter is instructed (S27). Also, when it is decide that no lower band neighboring station exists, the receiving of the channel of a higher band neighboring station is instructed (S24). At this time, when it is decided that a higher band neighboring station exists, the selection of the narrowband filter is instructed (S27). When it is decided that neither higher band neighboring station exists, the selection of a wideband filter is instructed (S26). Thus, the broadcast channel can be received efficiently without the special provision of the bandpass filter for detecting the interference signal. COPYRIGHT: (C)2007,JPO&INPIT
