ABSTRACT:
If it is determined that a current time when a power switch is operated manually is equal to or close to a reservation time indicated by preset reservation time data, a power source automatically starts supplying a power source current to individual circuits of a broadcasting receiving apparatus main body. Otherwise, supply of a power source current to the individual circuits is not performed. This prevents a receiving unit from unnecessarily receiving a broadcasting electric wave. When completion of broadcasting of all broadcasting contents of a broadcasting program is detected, the power source stops supplying the power source current to the individual circuits of the broadcasting receiving apparatus main body. This also prevents the receiving unit from unnecessarily receiving a broadcasting electric wave.
