<P>PROBLEM TO BE SOLVED: To provide a switching device built-in apparatus and an inhibition method for broadcast reception disturbance capable of inhibiting broadcast reception disturbance caused in the vicinity of switching devices because of operation of a built-in switching device. <P>SOLUTION: In a broadcast reception device 100A having a class D amplifier that works in response to switching signals, a control unit 190A identifies the current position of the broadcast reception device 100A based on a positioning result CPT transmitted from a position detection unit 160. Next, the control unit 190A makes reference to a reception frequency table 171 in a storage unit 170 based on the identified current position, and reads a broadcast frequency receivable in a region covering the current position, that is, the region where the broadcast reception device 100A is present. Consequently, the control unit 190A determines a switching frequency capable of inhibiting the broadcast reception disturbance corresponding to the receivable broadcast frequency based on the read broadcast frequency. <P>COPYRIGHT: (C)2012,JPO&INPIT |
