Claim:
A simultaneous broadcasting receiver comprising: a first receiver for receiving a first broadcasting signal broadcast in a first broadcasting system and applying predetermined signal processing to the received first broadcasting signal; a second receiver for receiving a second broadcasting signal transmitted by using a second broadcasting system different from the first broadcasting system and transmitting a broadcasting content in synchronization with an identical broadcasting content transmitted by the first broadcasting signal, the second receiver for applying predetermined signal processing to the received second broadcasting signal; a reception status detector for detecting a reception status of the first broadcasting signal; an input system selector for selecting between a processed signal obtained in the first receiver and a processed signal obtained in the second receiver and outputting the selected signal to a circuit following thereto; a power supply controller for controlling supplying power to the second receiver; and a controller for controlling the input system selector and the power supply controller according to a detection result obtained by the reception status detector, wherein the controller controls the input system selector and the power supply controller so that, a) when the reception status of the first broadcasting signal is better than a first status, power is not supplied to the second receiver and the processed signal obtained in the first receiver is selected and outputted; b) when the reception status of the first broadcasting signal is poorer than the first status and better than a second status, power is supplied to the second receiver and the processed signal obtained in the first receiver is selected and outputted; and c) when the reception status of the first broadcasting signal is poorer than the second status, power is supplied to the second receiver and the processed signal obtained in the second receiver is selected and outputted.
