Abstract:
The present invention discloses a broadcast reception device including a connection section for connecting to a smart antenna that switches directivity or a unidirectional antenna with fixed directivity connected; a first channel search section for executing channel search in the smart antenna; a second channel search section for executing channel search in the unidirectional antenna; a communication section for providing the connected smart antenna with power and a control signal; and a connection detection section for detecting a voltage of the communication section varied by voltage drop caused by the communication section connected to the smart antenna, and detect one of presence and absence of connection of the smart antenna based on a result of the detection, the first channel search section is selected to execute the channel search when the connection detection section detects the connection of the smart antenna, and the second channel search section is selected to execute the channel search when the connection detection section does not detect the connection of the smart antenna.
