a control system coupled to said multiport transmitter means and to said videodisc player for controlling the application of video sequences to said television monitors, said control system responsive to said microcomputers and said microcomputer output signals so that video sequences reflective of information indicative of the results of evoked responses are applied to the television monitors corresponding to the microcomputers which have been operated by said students to generate the corresponding microcomputer output signals shortly after such microcomputer output signals have been generated, said control system comprising;
a video digitizer connected to said videodisc player for converting video sequences recorded on said videodisc and played by said videodisc player into digitized video signals;
a video compressor coupled to said digitizer for compressing said digitized video signals;
a computer memory coupled to said video compressor for storing compressed digitized video signals;
digital to analog converting means coupled to said memory and to said multiport transmitter means for converting digitized video signals stored in said memory into analog video signals for application through said multiport transmitter means to said television monitors; and
wherein said control system causes said videodisc player to play sequences indicative of the results of possible evoked responses into said video digitizer for conversion into digitized video signals, to compress those signals in said video compressor, to store those signals in said computer memory, and thereafter to apply those stored, compressed, digitized signals through said digital to analog converting means through said multiport transmitter means to said television monitors corresponding to the microcomputers which have been operated by said students to generate the corresponding microcomputer output signals, any of said stored compressed digitized video signals being so applicable to any of said television monitors whereby different signals are simultaneously applied to different television monitors when said students simultaneously operate said microcomputers to generate different microcomputer output signals.

Abstract
A system for simultaneously interactively training a plurality of students at student stations which may be remote from one another is described. A videodisc player capable of accessing any portion of a videodisc on which has been recorded instructional materials is coupled to a television monitor at each student station. Each student station also comprises a microcomputer into which the student inputs his or her response to the situations presented on the television monitor by the videodisc player. In one embodiment, selected video signals from the videodisc on the videodisc player are digitized and stored in a computer memory. These stored video signals may represent simulated outcomes corresponding to the reponses of the students. Thereafter, the different responses of the students cause either the video signals stored in the computer memory to be converted into analog format and applied to the appropriate television monitors, or causes the videodisc player to access an appropriate portion of the videodisc. A multiport transmitter controllable by signals from the microcomputers results in the appropriate video signals being applied to the appropriate television monitors. In the present invention, fiber optic video links between the videodisc player and the television monitors permit interference-free transmission even within structures or in an industrial area in which the students are remotely located from one another and from the videodisc player.
