  • Patent number: 4924303
    Abstract: A TV still frame image, perhaps with an accompanying audio segment, information retrieval system is disclosed. The system allows end users to search for, order, and retrieve still frame video images, which images are then displayed on a conventional television set. Related audio sound can be heard over the same television set, over a telephone, or over another audio device. A data base of images and sound is stored on storage devices that are controlled by a general purpose computer system. This data base is located at the "head end" of the system. In one mode of operation, an end user requests and receives a particular video image(s), and perhaps a sound segment(s), from a plurality of such images that are continuously being sent to all end users. In a second mode of operation an end user requests a data base image that is not presently being sent to all end users.
