Abstract

A broadcast reception apparatus is connected to a directional antenna capable of changing an airwave reception direction. The broadcast reception apparatus includes a tuner selecting a frequency of airwave received by the directional antenna. When a prescribed condition is satisfied, power is supplied to the tuner, and thereafter power is supplied to the directional antenna.

Claims

1. A broadcast reception apparatus comprising:

a connection portion connected to a directional antenna capable of changing an airwave reception direction;

a tuner selecting a frequency of airwave received by said directional antenna; and

a control unit accepting power supply from an external power supply and controlling a manner of power supply from the external power supply to said tuner and said directional antenna;

wherein

said control unit allows power supply to said directional antenna after power supply to said tuner.

2. The broadcast reception apparatus according to claim 1, further comprising a determination unit determining whether said directional antenna is properly connected to said connection portion;

wherein

said control unit causes an operation to supply power to said directional antenna to stop when said determination unit determines that said directional antenna is not properly connected to said connection portion after power supply to said directional antenna is started.

3. The broadcast reception apparatus according to claim 2, wherein said determination unit includes

a transmission unit transmitting a prescribed signal to said directional antenna,

a reception unit receiving a signal from said directional antenna, and

a decision unit deciding whether said reception unit has received a specific signal, and

when said decision unit decides that said reception unit has received said specific signal, said determination unit determines that said directional antenna is properly connected to said connection portion.

4. The broadcast reception apparatus according to claim 2, wherein

said control unit controls a direction of airwave reception by said directional antenna,

said determination unit includes

a transmission unit transmitting a prescribed signal to said directional antenna,

a reception unit receiving a signal from said directional antenna, and

a decision unit deciding whether said reception unit has received a specific signal, and

when said decision unit decides that said reception unit has not received said specific signal or when a manner of reception is not changed even if said control unit causes the direction of reception by said directional antenna to change with regard to the airwave in a specific channel, said determination unit determines that said directional antenna is not properly connected to said connection portion.

5. The broadcast reception apparatus according to claim 1, further comprising an output portion outputting information based on the airwave received by said directional antenna, wherein

said control unit controls a manner of power supply from the external power supply to said output portion, and allows power supply to said directional antenna after power supply to said output portion when said prescribed condition is satisfied.

6. The broadcast reception apparatus according to claim 5, wherein

said output portion is a television outputting image and sound based on the airwave received by said directional antenna.
