Abstract:

A computer controlled video interactive courseware system is designed for the generation, viewing, and duplication of interactive instructional video tapes. An interactive instructional videotape contains video segments located on the stereo-video portion of a tape containing live-motion video images for the presentation of a lesson. Portions of the stereo-video portion of the tape contains video signals that contain digitally encoded information which is retrieved by the computer during playback of the tape. The digital information extracted from the videotape contains computer instructions to provide interactivity with students. Interactivity could include a presentation of questions to the student and based on the student's response to the question presenting selected video segments from the video tape. Preferably, the video cassette recorder is S-VHS which provides for increased bandwidth and uses a higher quality tape medium than standard VHS tape medium.
