Monitoring Behavior of Listening to Broadcast
First Claim
1. A device for monitoring behavior of listening to broadcast, comprising:
- a transmitter transmitting a characteristic audio signal which is modulated on a carrier signal;
a collector collecting an ambient sound;
a detector detecting whether the collected ambient sound contains the characteristic audio signal; and
a determiner determining whether a broadcast receiving apparatus receives the broadcasting channel corresponding to frequency of the carrier signal according to the result of the detector.
