Abstract
A multimedia search and indexing system automatically selects scenes or events of interest from any media, i.e., video, film, sound for replay, in whole or in part, in other contexts. The entire audio track of a recorded event in video, film, sound, etc., is analyzed to determine audio levels within a set of frequency ranges of interest. Audio clip levels within the selected frequency ranges are chosen as audio cues representative of events of interest in the track. The selection criteria are applied to the audio track of the recorded event. An Edit Decision List (EDL) is generated from the analysis of the audio track. The list is representative of scenes or sounds of interest as clips for reuse. The clips are reviewed and accepted or rejected for reuse. Once selected, the clips are edited using industry standard audio and video editing techniques.
