Television electronic control circuit for channel selections
Abstract
Abstract AN ELECTRONICALLY CONTROLLED TUNER FOR A TELEVISION RECEIVER IS AUTOMATICALLY TUNED FROM ONE TO ANOTHER OF PRESELECTED CHANNELS. A CONTROL CIRCUIT FOR CHANNEL SELECTION IS ADAPTED TO ENERGIZE A PLURALITY OF TUNER CONTROL TERMINALS AND CHANNEL IDENTIFICATION TERMINALS EACH CORRESPONDING TO A PARTICULAR CHANNEL. THE CONTROL CIRCUIT IS ACTUATABLE TO AUTOMATICALLY CHANGE THE TUNING OF THE RECEIVER TO A SELECTED CHANNEL AND INCLUDES A COUNTER WHICH IS ENERGIZED BY AN OSCILLATOR. MEANS ARE RESPONSIVE TO SUCCESSIVE COUNTS PRODUCED BY THE COUNTER TO APPLY A CONTROL SIGNAL TO A DIFFERENT ONE OF SAID TUNER CONTROL AND CHANNEL IDENTIFICATION TERMINALS FOR CAUSING SAID RECEIVER TO BE TUNED FROM CHANNEL TO CHANNEL IN SUCCESSION WITH EACH CHANNEL BEING IDENTIFIED. THE MEANS ARE RESPONSIVE TO COUNTS CORRESPONDING TO CHANNELS WITHIN THE PRESELECTED GROUP FOR DISABLING THE OSCILLATOR EACH TIME THE COUNTER REACHES ONE OF THE COUNTS.
