Abstract

비데오 신호에 문자신호를 복합하여 출력시키는 장치에 관한 것으로서, 입력 비데오 신호의 페데스탈 레벨을 바이어스부로부터 제공되는 특정 레벨의 전압으로써 안정화시키는 안정화 회로를 구비하여 안정된 비데오 신호에 문자 신호를 복합 출력함으로써 동기가 무너지고 문자의 밝기가 달라지는 현상을 방지하는 효과가 있다. 이것은 비데오 신호에 문자 신호를 복합하는 모든 장치에 이용 가능하다.The present invention relates to a device for outputting a composite of a text signal to a video signal. The apparatus includes a stabilization circuit for stabilizing a pedestal level of an input video signal by a voltage of a specific level provided from a bias unit. And the brightness of the characters are changed. This is available for all devices that combine text signals with video signals.
