System and method for surveying broadcasting ratings
摘要:
The present invention relates to a system and method for surveying broadcast ratings. The present invention provides a system for surveying broadcast ratings, including: a television (TV) signal reception device configured to receive a broadcast signal, to send the broadcast signal to a TV, and to send an event signal to a rating statistics information server when a predetermined condition occurs; the rating statistics information server configured to send a fingerprint extraction request signal to a previously registered user terminal when receiving the event signal from the TV signal reception device; and the user terminal configured to extract the fingerprint data of an audio signal generated from the TV being watched by a user when receiving the fingerprint extraction request signal from the rating statistics information server, and to send the extracted fingerprint data and user identification information to the rating statistics information server; wherein the rating statistics information server obtains the channel identification information of a TV channel being watched by the user based on the fingerprint data transmitted by the user terminal, and generates rating statistics information based on the obtained channel identification information and the user identification information, and also provides a method using the same.
