Abstract :
To improve library access, the 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 map can also serve as a query mechanism, allowing users to search the terabyte library for stories taking place in a selected area of interest. This article discusses using interactive maps with the Informedia Digital Video Library
