Content auditing using video signatures

The large amount of broadcast and multimedia distribution channels introduces a new challenge for the advertisement industry. Keeping track of ad placements and effectiveness is highly necessary. This paper introduces a novel method for content monitoring and control through the use of video signatures. A video tomography based video signature is used. The goal is to determine the number of times a particular advt. clip is included in a video stream. The proposed method is low complexity and can monitor video streams in real-time. The proposed method not only allows the monitoring of the broadcast transmission, but also permits the extraction of user statistical behavior if this solution is included in setup boxes.
