ABSTRACT:
Method for automatically controlling the optimal tuning point for receiving teletext increases or decreases the tuning point of steps of a certain frequency for the byte error at each step tuning point to be detected and memorized so that the tuning point for the minimal byte error is found to provide the optimal tuning frequency for receiving a teletext, thus eliminating the inconvenience of manipulating a key to find the optimal tuning point from the display on a TV screen. The system of the method employs a microprocessor and teletext processor in addition to the tuner.
