Abstract: System and method for detecting and classifying direct response advertisements.

Abstract: The present invention relates to an advertisement detection system based on fingerprints, and provides an advertisement detection systems based on fingerprints, including a content stream storage unit for storing broadcast content in real time, a section selection unit for selecting a reference section and a test section from broadcast content stored by the content stream storage unit, a fingerprint extraction unit for extracting fingerprints from the reference section and the test section selected by the section selection unit using one or more methods, a fingerprint matching unit for comparing the fingerprints from the test section and the reference section, extracted by the fingerprint extraction unit, with each other and then performing matching between the fingerprints, an advertisement section determination unit for determining advertisement segments from the test section based on results of the matching performed by the fingerprint matching.

Abstract: The present invention relates to a system and method for providing information related to an advertisement included in a broadcast over a network.

Abstract: 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.

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.

Abstract: The present invention relates to a system and method for providing additional information using image matching. The present invention provides a system for providing additional information using image matching, including: a image input unit configured to receive a video or an image input from a user terminal; a query image determination unit configured to determine a query image, i.e.

Abstract: The present invention relates to a method and system for constructing a database (DB) based on mutual relations between pieces of video data. The present invention provides the method of constructing a DB based on mutual relations between pieces of video data, including 1) generating one or more nodes so that pieces of identical video data are included in an identical node, 2) generating pieces of node information about respective generated nodes, 3) comparing comparison target video data with pieces of video data of the respective nodes, and then setting relations between the comparison target video data and the pieces of video data of the respective nodes, and 4) updating pieces of node information about the respective nodes, based on the set relations, and also provides a DB construction system using the method.

Abstract: The present invention relates to a device and method for analyzing the correlation between an image and another image or between an image and a video.
