The Informedia Digital Video Library contains over 1200 hours of video. Through automatic processing, descriptors are derived for the video to improve library access. A new extension to the video processing is the extraction of geographic references from these descriptors. The operational library interface shows the geographic entities addressed in a given story, highlighting the regions discussed at any point in the video through a map display synchronized with the video playback. The map can also be used as a query mechanism, allowing users to search the terabyte library for stories taking place in a selected area of interest.
