SYSTEM AND METHOD FOR SURVEYING BROADCASTING AUDIENCE RATING

摘要

The present invention relates to a broadcast rating survey system and a method. The system includes a TV signal receiving device transmitting a broadcast signal to a TV by receiving the signal and transmitting an event signal to a rating statistic information server when a preset condition is set, a rating statistic information server transmitting a fingerprint extraction request signal to a pre-registered user terminal when receiving the event signal from the TV signal receiving device, and a user terminal extracting fingerprint data about an audio signal generated in the TV that a user is watching when receiving the fingerprint extraction request signal from the rating statistic information server and transmitting the fingerprint data and user identification information to the information server. The rating statistic information server obtains channel identification information of a TV channel that the user is watching based on the fingerprint data and generates rating statistic information based on the user identification information and the channel identification information.
