Abstract
A system and method in which a TV signal reception device (e.g., set top box) receives a broadcast signal, sends the broadcast signal to a TV, and sends an event signal to a rating statistics information server or associated user terminal when a predetermined condition occurs, to ultimately cause an associated user terminal to generate fingerprint data of audio from the TV and to provide the fingerprint data to the server so as to facilitate channel identification and generation of ratings statistics.

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 the generated fingerprint data to a server to enable the server to determine channel identification information of the broadcast TV signal and generate rating statistics information.
A television signal (TV) reception device configured to receive a broadcast TV signal, wherein the TV signal reception device is configured to detect when the broadcast TV signal is a given TV channel for a predetermined time, and
- wherein the TV signal reception device is configured to respond to the detecting by sending to a user terminal a control signal that causes the user terminal to generate fingerprint data from the TV channel and to send the generated fingerprint data to a server to enable the server to determine channel identification information of the broadcast TV signal and generate rating statistics information.
