Abstract
A system for viewing digital video stored in a remote location allows a user to first request a visual summary of the video which consists of still images corresponding to the frames where scenes change and then allows the user to utilize this information to control the playback of the audio track using the keypad of a touch-tone phone. The first main component, a digital video pre-processor, extracts information from the original video. This is performed in advance of the user's access. The second main component, a phone-based video-playback attendant, receives remote instructions from the user via the telephone and presents the requested information.
