1. A method comprising:
receiving by a television (TV) signal reception device a broadcast TV signal;
detecting by the TV signal reception device when the broadcast TV signal is a given TV channel for a predetermined time; and
responsive to the detecting, sending from the TV signal reception device to a user terminal a control signal that causes the user terminal to generate fingerprint data from the TV channel and to send to a server the generated fingerprint data,
wherein the user terminal sending the generated fingerprint data to the server enables the server to obtain channel identification information of the TV channel based on the generated fingerprint data and to generate rating statistics information based on the obtained channel identification information.
