摘要:
A system and method for the automated real-time detection and processing of commercial messages, public service announcements or similar short-duration, repeated TV programing segments occurring in one or more broadcast video steams is described. A process is utilized that identifies possible commercial segments by identifying discrete video segments that have specific short durations among other attributes. Video segments that appear to have these characteristics are considered likely to be television commercials, promotions, or public service announcements and are stored in a TV Ad database which is separate from the primary television content database. Incoming video from a plurality of television programming sources is process into fingerprints and placed in a master TV content database. At the same time, said incoming programming is tested for matches in a TV ad database. If a match is found, then the presumed TV ad is removed from the master content database.

The invention relates to the analysis of characteristics of audio and/or video signals for the generation of audio-visual content signatures. To determine an audio signature a region of interest - for example of high entropy - is identified in audio signature data. This region of interest is then provided as an audio signature with offset information. A video signature is also provided.
摘要:
A system and method for the identification of specific video segments in a video program, such as certain TV commercials, is presented. A means is described for an accelerated identification of the video segment of interest in conjunction with a means to communicate said information to a process in a remote television system such that the remote television system can anticipate the future start of said video segment of interest and display contextually related material in close proximity to the start of said video segment.
