Abstract
A television receiver cuts power supply to its built-in device which is overlapped with that of the external unit connected to the television receiver for reducing power consumption to cope with diversification of the external unit. The television receiver includes the tuner which receives a television broadcast signal, an external unit connection portion which connects the external unit with the HDMI cable, the HDMI process unit which acquires unit information data from the connected external unit to transmit video/audio data, and the power supply circuit which supplies power to the tuner. If the HDMI process unit determines that the connected external unit includes the same function as the tuner, the control unit allows the power supply circuit to stop power supply to the tuner.
