Abstract
A TV receiver comprises: a tuner connected to a unidirectional antenna or a smart antenna; a reception control unit for outputting, to the tuner, a channel control signal to command a channel, and outputting, to the smart antenna, a receiving direction control signal to command a receiving direction; and an antenna selection switch for a user to select the either antenna. The reception control unit switches its control mode between a unidirectional antenna mode and a smart antenna mode. In the unidirectional antenna mode, the reception control unit outputs a channel control signal to the tuner. In the smart antenna mode, the reception control unit outputs the channel control signal and the receiving direction control signal to the tuner and the smart antenna, respectively, for controlling the TV signal reception. This TV receiver can properly switch the antenna control mode, depending on the kind of antenna selected by the user.
