Television system with improved definition in field scanning direction

摘要: A television system with enhanced definition in the field scanning direction is presented. In information transmitter a video signal source coupled directly and via line delay device subtraction circuit followed by modulator subcarrier. An adding output of source, possibly device. The resultant difference transmitted frequency-interleaved under control movement detector, to receiver. receiver contains filter for separating information. modulated subcarrier goes demodulator superposition which further also supplied. connected one input switch-over circuit. supplied second on said first inputs passed during alternate periods. result an improvement picture upon display direction.
