Abstract
An audio visual system includes an audio cassette tape player, a central processor unit, a TV screen for displaying a desired pattern in accordance with a data derived from the audio cassette tape player, and a speaker system for providing audio announcement in accordance with information derived from the audio cassette tape player. The audio visual system displays a problem and five typical answers thereto. The student introduces his answer through a keyboard unit. When, for example, an answer key 3 is actuated, the audio visual system drives the audio cassette tape player to locate a commentary suited for response to the actuation of the answer key 3 whereby the commentary associated with answer key 3 is displayed and announced.
Claims24
An audio visual system comprising:
- reproduction system means for developing audio sound information, digital picture data information, and digital operation instruction commands from a recording medium containing a plurality of data sections, each of said data sections having said audio information provided on a first track separate from a second track having said picture data information and operation instruction commands stored thereon, said audio information being recovered from said first track substantially simultaneously with the recovery of said picture data information and said operation instruction commands from said second track;
- speaker system means responsive to the audio sound information developed from said reproduction system means for generating audio sound in accordance with said audio sound information developed by said reproduction system means;
- video control means responsive to the picture data information and the operation instruction commands developed from said reproduction system means for providing a video signal in accordance therewith;
- an image screen for providing a visual image in response to said video signal;
- and
- input means connected to said reproduction system means for selecting a desired one of said data sections stored in said recording medium, said reproduction system being controlled in response to the selection of the desired data section via said input means and in response to said digital operation instruction commands recorded on said recording medium.
An audio visual system for generating a visual display on the screen of a television and for producing an audio sound corresponding thereto, said system comprising:
- picture signal processing means connected to the television for producing a video signal, said video signal producing said visual display on the television screen;
- input means connected to said picture signal processing means for developing a command in response to selection by said input means, said picture signal processing means receiving said command and developing a command operation signal therefrom;
- tape player means connected to said picture signal processing means and responsive to said command operation signal for generating audio sound signals and instruction command signals therefrom in response thereto, said instruction command signals including pattern data and color data;
- said picture signal processing means including,
- first memory means for storing said pattern data therein,
- second memory means for storing said color data therein,
- means for combining said pattern data stored in said first memory means with said color data stored in said second memory means to produce combined picture data;
- means for converting said combined picture data produced by said means for combining into a further video signal;
- television monitor means for converting said further video signal into another visual display on the television screen;
- and
- said tape player means producing an audible message in response to said sound signals substantially simultaneous to the generation of said another visual display on said television screen whereby said picture signal processing means controls the visual display on the screen of said television in response to the command developed by said input means and in response to said instruction command signals generated from said tape player means.
An electronic learning aid for generating at least one problem and a series of answers on the screen of a television and for producing an audio output corresponding to a selected answer to said problem, said learning aid comprising:
- picture signal processing means connected to said television for producing a video signal, said video signal producing said problem and said series of answers on the television screen;
- input means connected to said picture signal processing means for selecting one of said series of answers and producing a command signal indicative thereof;
- said picture signal processing means receiving said command signal and developing a command drive signal therefrom;
- tape player means connected to said picture signal processing means and responsive to said command drive signal for developing audio sound signals and instruction command signals, said instruction command signals including pattern data and color data, said tape player means delivering said instruction command signals to said picture signal processing means corresponding to said selected answer;
- said picture signal processing means including,
- first memory means for storing said pattern data therein,
- second memory means for storing said color data therein,
- means for combining said pattern data stored in said first memory means with said color data stored in said second memory means to produce combined picture data,
- means for converting said combined picture data produced by said means for combining into a further video signal;
- television monitor means for converting said further video signal into a visual display on the television screen, said visual display being associated with said selected answer;
- and
- said tape player means producing an audible commentary message associated with said selected answer in response to said audio sound signal substantially simultaneously with the generation of said visual display on said television screen.
An electronic learning aid system for generating a visual display on a television screen and for commenting on a user response to problems presented on said visual display, said system comprising:
- input means for allowing the user to respond to the problems presented in said visual display by selecting an answer thereto and producing an answer signal representative
- tape player means responsive to said answer signal for reading picture data information from a tape, said picture data information being indicative of desired changes of said visual display;
- memory means for storing information corresponding to the visual display to be generated on said television screen;
- means for altering the information stored in said memory means in response to said picture data information indicative of desired changes;
- means for repeatedly and sequentially reading the information stored in said memory means and for converting said information into a video signal;
- and
- television monitor means including said television screen for converting said video signal into the visual display on said television screen.
