Method and system for recognition of broadcast segments

摘要

The broadcast audio signal and/or the broadcast video signal of a monitored broadcast are temporarily stored and predetermined signal events are detected which indicate possible new broadcast segments of interest of the monitored broadcast. Intervals of the monitored broadcast are selected as possible new broadcast segments of interest based on the predetermined signal events. A first capture level is assigned to a first selected interval based on predetermined characteristics of the interval which indicate that it is likely to be a new segment of interest. A second capture level is assigned to a second selected interval based on predetermined characteristics of that interval which indicate that it is relatively less likely than the first selected interval to be a new segment of interest. A signature corresponding with the first selected interval is stored in the database and the temporarily stored broadcast audio and/or video signals which correspond with the first selected interval are captured for transmission to a workstation operator for segment identification. A signature corresponding with the second selected interval is stored in the database and the temporarily stored broadcast audio and/or video signals which correspond with the second selected interval are erased.
