Radio device
First Claim
1. A radio device including an antenna unit and a device main unit and a cable connecting the antenna unit with the device main unit, the radio device transmitting a radio frequency signal transmitted or received by the antenna unit between the antenna unit and the device main unit via the cable, comprising:
- a communication interface configured to transmit a communication signal differing from the radio frequency signal between the antenna unit and the device main unit via the cable;
a defect detector configured to monitor a transmission state of the communication signal by the communication interface to detect a defect between the antenna unit and the device main unit on the basis of the monitoring result; and
a presentation controller configured to control presentation of detection result from the defect detector to a user of the radio device.

Abstract
A device main unit transmits a bus reset pulse to an antenna unit via a cable transmitting a television reception signal, a controller of the device main unit detects a response of a presence pulse to the bus reset pulse and displays the detection result. The transmission of the bus preset pulse and the reception of the presence pulse are performed by utilizing the existing communication interface with 1-Wire type interactive baseband communication system disposed to control a tunable radio frequency circuit provided for the antenna unit from the controller adopted thereto.

6. A radio device including an antenna unit and a device main unit and a cable connecting the antenna unit with the device main unit, the radio device transmitting a radio frequency signal transmitted or received by the antenna unit between the antenna unit and the device main unit via the cable, comprising:
-
a transmitter configured to transmit a communication signal to the antenna unit; a defect detector configured to detect a defect between the antenna unit and the device main unit by monitoring a transmission state of the communication signal; and a informing controller configured to inform presentation of detection result from the defect detector to a user of the radio device.
