Video surveillance system employing video primitives

A video surveillance system extracts video primitives and extracts event occurrences from the video primitives using event discriminators. The system can undertake a response, such as an alarm, based on extracted event occurrences.

ELECTRIC COMMUNICATION TECHNIQUE

Selective content distribution, e.g. interactive television or video on demand [VOD] -Client devices specifically adapted for the reception of or interaction with content, e.g. set-top-box [STB]; Operations thereof-Processing of content or additional data, e.g. demultiplexing additional data from a digital video stream; Elementary client operations, e.g. monitoring of home network or synchronising decoder's clock; Client middleware -Processing of video elementary streams, e.g. splicing a video clip retrieved from local storage with an incoming video stream or rendering scenes according to encoded video stream scene graphs-involving rendering scenes according to scene graphs, e.g. MPEG-4 scene graphs
