Claims (1)

수직동기신호에 의해 시간 지연된 펄스를 발생시켜 디지탈 색차 데이타 및 다중화 동기신호가 복합되어 있는 다중색차신호에서 다중화 동기 신호만 추출하기 위한 윈도우 펄스를 발생시키는 윈도우 발생회로부(1) 및 게이트G1(2)G2(3)에 의해 반전되고 윈도우 신호에 의해 추출된 다중화 동기신호를 입력하여 데이타 클럭에 의해 시프트하는 순환펄스를 발생시키는 시프트 레지스터(5)와 시프트레지스터(5)의 병렬 출력에 의해 순환적으로 다중 색차신호를 받아들이는 래치(6a,6b,6c,6d)로 구성되며, 게이트G3(4)는 추출된 다중화 동기펄스가 없어도 링카운터 회로부(5)의 직렬 출력에 의해 순환펄스를 계속 발생시키도록 하고 윈도우 발생회로부(2)에서 출력되는 리세트신호는 시프트 레지스터(5)를 윈도우 신호의 시작점에서 리세트시키는 것을 특징으로 하는 디지탈 텔레비젼(TV) 신호용 다중화 동기신호 재생장치.The window generating circuit unit 1 and the gate G 1 (2) generating a pulse delayed by the vertical synchronization signal to generate a window pulse for extracting only the multiplexed synchronization signal from the multicolor difference signal including the digital color difference data and the multiplexed synchronization signal. Circulation by the parallel output of the shift register 5 and the shift register 5 which inputs the multiplexed synchronization signal inverted by G 2 (3) and generates a cyclic pulse shifted by the data clock by inputting the multiplexed synchronization signal. It is composed of latches 6a, 6b, 6c, and 6d that accept multiple color difference signals, and gate G 3 (4) generates a circulating pulse by the serial output of the ring counter circuit section 5 even without the extracted multiplexed synchronization pulses. And the reset signal output from the window generating circuit section 2 resets the shift register 5 at the start of the window signal. Is a multiplexed synchronous signal reproduction apparatus for digital television (TV) signals. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
