Abstract
A device and a method for monitoring behavior of listening to broadcast comprises 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.
