A method and system for continually storing and cataloguing streams of broadcast content, allowing real-time searching and real-time results display of all catalogued video. A bank of video recording devices store and index all video content on any number of broadcast sources. This video is stored along with the associated program information such as program name, description, airdate and channel. A parallel process obtains the text of the program, either from the closed captioning data stream, or by using a speech-to-text system. Once the text is decoded, stored, and indexed, users can then perform searches against the text, and view matching video immediately along with its associated text and broadcast information. Users can retrieve program information by other methods, such as by airdate, originating station, program name and program description. An alerting mechanism scans all content in real-time and can be configured to notify users by various means upon the occurrence of a specified search criteria in the video stream. The system is preferably designed to be used on publicly available broadcast video content, but can also be used to catalog private video, such as conference speeches or audio-only content such as radio broadcasts.
