To improve library access for video information, Carnegie Mellon University's Informedia Digital Video Library uses automatic processing to derive descriptors for video. A new extension to the video processing extracts geographic references from these descriptors. The operational library interface shows the geographic entities addressed in a given story, highlighting the regions discussed in the video through a map display synchronized with the video playback. The article expatiates on the Library's accessing video through spatial queries, map representation of a video segment and future of video information retrieval.
