Patent ID: 8126416

Claim:
A broadcast receiving apparatus, comprising: a connection circuit connectable to a variable directivity antenna and a directional antenna; a tuner connected with the connection circuit for performing reception process of broadcast waves; and a control unit performing power supply to the variable directivity antenna and directivity control of the variable directivity antenna, the broadcast receiving apparatus further comprising: a first power receiving terminal for supplying necessary power to the broadcast receiving apparatus; a second power receiving terminal for supplying necessary power to the variable directivity antenna; a decision circuit for determining whether or not power is supplied to the second power receiving terminal; a drive control circuit, when the decision circuit determines that the power is supplied to the second power receiving terminal, for driving the control unit to perform control of the variable directivity antenna; a first power supply control circuit for controlling power supply to the variable directivity antenna; and a second power supply control circuit for controlling power supply to units related to the variable directivity antenna; wherein if the power is supplied to the second power receiving terminal when the power is being supplied to the first power receiving terminal, the first power supply control circuit starts the power supply to the variable directivity antenna; and if the power is not supplied to the second power receiving terminal when the power is being supplied to the first power receiving terminal, the first power supply control circuit does not start the power supply to the variable directivity antenna and the second power supply control circuit stops the power supply to the units related to the variable directivity antenna.
