Abstract:
A broadcast receiving apparatus includes a first tuner configured to receive a broadcast wave from a specified broadcasting station, a second tuner configured to perform a frequency search for receivable broadcasting stations, a power supply unit configured to supply power to the first tuner and the second tuner, a traveling state detection unit configured to determine if a vehicle is moving or is stopped, a reception state detection unit configured to detect a reception state of a currently-received broadcast wave, and a control unit configured to control the first tuner, the second tuner, the power supply unit, the traveling state detection unit, and the reception state detection unit. The control unit causes power to be supplied to the second tuner and causes the second tuner to perform a frequency search while the vehicle is traveling, and when it is determined that the vehicle has stopped, the control unit turns the power supplied to the second tuner on and off in accordance with the reception state of the broadcast wave.
