Abstract

방송방식에 따른 수평/수직동기위치 보정회로는 인가되는 방송방식에 따라 서로 상이하게 나타나는 수평 및 수직동기신호의 위치를 자동적으로 보정하기 위한 것으로서, 인가된 방송방식이 엔티에스씨방송식이면 수평동기신호와 수직동기신호에 미리 설정된 임의의 값을 더하여 새로운 수평동기신호와 수직동기신호로 변환되고, 인가된 방송방식이 엔티에스씨방송방식이 아닐 경우에는 인가된 방송신호를 그대로 출력하도록 함으로써, 별도의 보정회로를 구성하지 않고 기존의 회로를 이용하여 수평 및 수직동기신호의 위치를 자동으로 보정하였다. 이 것을 다중방송방식을 수신할 수 있는 모든 텔레비젼에 사용가능하다.The horizontal / vertical synchronous position correction circuit according to the broadcasting method is used to automatically correct the position of the horizontal and vertical synchronous signals which are different from each other according to the applied broadcasting method. By adding a predetermined value to the signal and the vertical synchronous signal, it is converted into a new horizontal synchronous signal and the vertical synchronous signal, and when the applied broadcast method is not the NC broadcast method, the applied broadcast signal is output as it is. Instead of constructing the correction circuit, the position of the horizontal and vertical synchronous signals is automatically corrected using the existing circuit. This can be used for all televisions that can receive multicast.
