VEHICULAR AUDIO/VISUAL SYSTEM AND METHOD OF CONTROLLING THE SAME
First Claim
1. A vehicular audio/visual system that receives a transmitted electric wave of video or sound, and that outputs the transmitted electric wave from an output unit, comprising:
- a positional information detecting unit that detects positional information of a vehicle;
a receiving area storage unit that stores at least one of an allowable area in which receiving the electric wave is allowed and a prohibited area in which receiving the electric wave is not allowed;
an allowable area determination unit that refers to the receiving area storage unit on the basis of the detected positional information and that determines whether receiving the electric wave is allowed; and
a prohibiting unit that prohibits power supply to an antenna amplifier of an antenna that receives the electric wave or power supply to a tuner connected to the antenna, when it is determined that receiving the electric wave is not allowed.

7. A method of controlling a vehicular audio/visual system that receives a transmitted electric wave of video or music, and that outputs the transmitted electric wave from an output unit, comprising:
-
detecting a current position of a host vehicle; determining, on the basis of the detected current position, whether the host vehicle is within an area in which receiving the electric wave is allowed; and prohibiting power supply to an antenna amplifier of an antenna that receives the electric wave or power supply to a tuner that is connected to the antenna, when it is determined that the host vehicle is outside the area in which receiving the electric wave is allowed. - View Dependent Claims (8)
