Abstract

본 발명은 오에스디 화면의 디스플레이시에 무신호시의 주파수 변동으로 인해 야기될 수 있는 오에스디 화면의 흔들림을 방지할 수 있도록 한 멀티 시스템에서 오에스디 흔들림 방지장치의 관한 것으로, 이를 위하여, 입력되는 색신호에 대하여 디스플레이 가능한 신호로 처리한 다음 R,G,B 신호에 복합영상신호에서 검출되는 동기신호에 의해 그 주파수 위치가 결정되는 오에스디 흔들림 방지장치에 있어서, 수평/수직 동기회로수단으로 부터 입력되는 무신호 판별신호에 의거하여 50Hz의 주파수를 갖는 동기신호를 발생시켜 크로마/편향 회로수단에 제공하는 동기신호 발생수단을 더 포함하여 구성함으로서, 무신호시에 강제적으로 동시주파수를 세팅시켜 줌으로서 동기주파수 인식오류로 인해 야기될 수 있는 화면상의 오에스디의 흔들림을 효과적으로 방지한 것이다.The present invention relates to an OSD anti-shake device in a multi-system that can prevent oscillation of the OSD screen, which may be caused by a frequency change at the time of no signal during display of the OSD screen. In the OSD anti-shake device in which the frequency position is determined by a synchronizing signal detected in a composite video signal to an R, G, and B signal, the signal is input from a horizontal / vertical synchronizing circuit means. The apparatus further comprises a synchronization signal generating means for generating a synchronization signal having a frequency of 50 Hz based on the non-signal discrimination signal and providing it to the chroma / deflection circuit means. This can effectively prevent the on-screen oscillation caused by the recognition error. It would have prevented.
