A method and apparatus to automatically index the locations of specified events on a video tape. The events, for example, include touchdowns, fumbles and other football-related events. An index to the locations where these events occur are created by using both speech detection and video analysis algorithms. A speech detection algorithm locates specific words in the audio portion data of the video tape. Locations where the specific words are found are passed to the video analysis algorithm. A range around each of the locations is established. Each range is segmented into shots using a histogram technique. The video analysis algorithm analyzes each segmented range for certain video features using line extraction techniques to identify the event. The final product of the video analysis is a set of pointers (or indexes) to the locations of the events in the video tape.
