Abstract: 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.

Abstract: The present invention relates to an apparatus and method for efficiently generating feature data which properly determines a feature point indicating features of images and describes the feature point. The apparatus for generating image feature data comprises: a feature point determining unit which determines a feature point from an image and extracts information on the determined feature point; a feature point filtering unit which determines, as a final feature point, at least one feature point from among the feature points determined by the feature point determining unit; and a feature data generating unit which generates image feature data based on the final feature points determined by the feature point filtering unit and feature point information on the final feature points.

Abstract: The present invention relates to an apparatus and method for recognizing content using an audio signal. The content recognition apparatus includes a query fingerprint extraction unit for forming frames having a preset frame length for an audio signal, and generating frame-based feature vectors for respective frames, thus extracting a query fingerprint. A reference fingerprint DB stores reference fingerprints to be compared with the query fingerprint and pieces of content information corresponding to the reference fingerprints. A fingerprint matching unit determines a reference fingerprint matching the query fingerprint. In this case, the query fingerprint extraction unit forms the frames while varying a frame shift size that is an interval between start points of neighboring frames in a partial section. According to the present invention, there can be provided a content recognition apparatus and method which can maintain the accuracy and reliability of matching while promptly providing results.
