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.

System and method for detecting and classifying direct response advertisements. The system includes a unit for generating an advertisement candidate segment for an advertisement section detected from a broadcast stream; a matching unit for determining whether the candidate segment matches each advertisement segment stored in a database (DB); a unit for, if the matching unit determines that a segment matching the candidate segment is not present, determining whether the candidate segment is a direct response advertisement; a registration unit for storing the candidate segment, determined to be a direct response advertisement, as an advertisement segment that is the direct response advertisement in the DB; and a direct response advertisement grouping unit for, if the matching unit determines that an advertisement segment matching the candidate segment is present, and the matching segment is a direct response advertisement, grouping the candidate segment with DB-stored advertisement segments that are direct response advertisements.

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.

In one aspect, a system for detecting and classifying direct response advertisements includes an advertisement candidate segment generation unit for generating an advertisement candidate segment for an advertisement section detected from a broadcast stream, a matching unit for determining whether the advertisement candidate segment matches an advertisement segment stored in an advertisement database (DB), a direct response advertisement determination unit for determining whether the advertisement candidate segment is a direct response advertisement if it is determined by the matching unit that an advertisement segment matching the advertisement candidate segment is not present, and a direct response advertisement grouping unit for grouping the advertisement candidate segment with advertisement segments that are direct response advertisements stored in the advertisement DB.

The present invention relates to a system and method for providing an image-based video service. The present invention provides a system for providing image-based video service, including a cache system configured to store video information that matches image-related data; a fingerprint extraction unit configured to extract the fingerprint of an image corresponding to input image-related data; and a matching unit configured to determine video information that matches the fingerprint of the image extracted by the fingerprint extraction unit; wherein the system for providing image-based video service determines video information, matching image-related data received from a client terminal, via the cache system or the matching unit, and transmits video result information corresponding to the determined video information to the client terminal, and a method using the same. According to the present invention, there are provided a system and method that can accurately determine a video or a frame corresponding to an image over a network, such as the Internet or a mobile communication, in real time and accurately perform playback from the corresponding video or frame.

A system and method detects and classifies direct response advertisements. An advertisement candidate segment generation unit generates an advertisement candidate segment from a broadcast stream, and a matching unit matches the advertisement candidate segment with an advertisement segment stored in an advertisement database. A direct response advertisement determination unit determines whether the advertisement candidate segment is a direct response advertisement, and a direct response advertisement registration unit stores an advertisement candidate segment determined to be a direct response advertisement as an advertisement segment in the advertisement database. A direct response advertisement grouping unit groups the advertisement candidate segment with advertisement segments that are direct response advertisements stored in the advertisement database.
