Abstract
A radio wave monitoring apparatus includes a television receiver which is capable of receiving a radio wave in a television broadcast frequency band and generates reception quality information, and a wireless communication device which is capable of establishing communication in an area to be monitored and a wider area than the area to be monitored and transmits the reception quality information.
Claims18
A radio wave monitoring apparatus comprising:
- a television receiver which is capable of receiving a radio wave in a television broadcast frequency band and generates reception quality information;
- and
- a wireless communication device which is capable of establishing communication in an area to be monitored and a wider area than the area to be monitored and transmits the reception quality information, wherein
- operation of a circuit block that is redundant to radio wave monitoring in the television receiver is stopped,
- only when an input signal indicates a great change, the circuit block is rendered operative to acquire the reception quality information, and
- an AGC signal is monitored, and when the AGC signal changes by an amount equal to or greater than a predetermined value, the reception quality information is acquired.
