Single picture selector system

Abstract

Abstract 1. AN ELECTRONIC SYSTEM WHEREIN A SINGLE COMPOSITE TELEVISION SIGNAL IS RECORDED AND REPORDUCED AND WHICH IS SELECTED FROM A MULTIPLE COMPOSITE TELEVISION SIGNAL HAVING VERTICAL SYNC SIGNALS, SAID ELECTRONIC SYSTEM COMPRISING: A SYNC PULSE SUPPLY MEANS TO RECEIVE THE MULTIPLE TELEVISION SIGNAL AND DEVELOP DELAYED VERTICAL SYNC PULSES FROM THE VERTICAL SYNC SIGNALS TO OCCUR DURING THE BLANKING INTERVALS AND AFTER THE EQUALIZING PULSES THEREOF, A TIMING SIGNAL SOURCE TO PROVIDE A SELECTOR SIGNAL INITIATED AT ANY SELECTED TIME, A SYNC GATE CONNECTED TO SAID SYNC PULSES SUPPLY MEANS AND TO SAID TIMING SIGNAL SOURCE TO PROVIDE A FIRST PULSE SIGNAL INCLUDING THE DELAYED SYNC PULSES FROM SAID SYNC PULSE SUPPLY MEANS OCCURRING DURING THE SELECTOR SIGNAL, AND TO PROVIDE A SECOND PULSE SIGNAL INCLUDING ALL THE OTHER DELAYED SYNC PULSES FROM SYNC PULSE SUPPLY MEANS, A SWITCH SIGNAL GENERATOR CONNECTED TO SAID SYNC GATE FOR DEVELOPING A SWITCH OPERATING SIGNAL INITIATED BY THE FIRST DELAYED SYNC PULSE OF SAID FIRST PULSE SIGNAL DURING SAID SELECTOR SIGNAL AND TERMINATED BY THE NEXT OCCURRING DELAYED SYNC PULSE OF SAID SECOND PULSE SIGNAL, A STORAGE DEVICE FOR RECORDING AND REPRODUCING SIGNAL COMPOSITE TELEVISION PICTURES AND INCLUDING A RECORD CIRCUIT, A REPRODUCE CIRCUIT, AND TRANSDUCER MEANS, SAID STORAGE DEVICE HAVING A ROTATABLE DRUM BEING RESPONSIVE TO THE VERTICAL SYNC SIGNALS OF THE MLTIPLE TELEVISION SIGNAL TO BE ROTATED IN SYNCHRONIZATION THEREWITH, AND AN ELECTRONIC CHANGEOVER CIRCUIT CONNECTED TO SAID SWITCH SIGNAL GENERATOR AND TO SAID STORAGE DEVICE AND INCLUDING A RECORD SWITCH CONNECTED BETWEEN THE RECORD CIRCUIT AND THE TRANSDUCER MEANS TO ALLOW THE PASSAGE THEREBETWEEN ONLY DURING THE SWITCH OPERATING SIGNAL, AND INCLUDING A REPRODUCE SWITCH CONNECTED BETWEEN THE REPRODUCE CIRCUIT AND THE TRANSDUCER MEANS TO ALLOW THE PASSAGE THEREBETWEEN AT ALL OTHER TIMES.
