Abstract
본 발명은 캡션 IC(Caption IC)로 인가되는 복합영상신호의 레벨을 일정하게 유지시켜 주는 텔레비젼 수상기의 캡션신호 자동 조절장치에 관한 것으로서, 영상신호를 캡션 IC(32)로 인가하여 캡션 테이터를 생성하도록 된 텔레비젼 수상기에 있어서, 영상신호의 전압을 검출하는 전압 검출수단(27)과, 이 전압 검출수단(27)에 의한 검출 전압을 디지탈 데이터로 변환하는 아날로그/디지탈 변환수단(28), 이 아날로그/디지탈 변환수단(28)에 의한 입력 데이터를 근거로 제어신호를 출력하는 제어수단(29) 및, 제어수단(29)으로부터의 제어신호에 따라 상기 영상신호의 전압을 조정하여 캐변 IC(32)로 출력하는 전압 조정수단(31)을 포함하여 구성된 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically adjusting a caption signal of a television receiver that maintains a constant level of a composite video signal applied to a caption IC, and generates caption data by applying a video signal to the caption IC 32. In a television receiver, a voltage detecting means 27 for detecting a voltage of a video signal, an analog / digital converting means 28 for converting a detected voltage by the voltage detecting means 27 into digital data, and the analog Control means 29 for outputting a control signal based on the input data by the digital / digital conversion means 28, and the voltage changer 32 adjusts the voltage of the video signal in accordance with the control signal from the control means 29. It characterized in that it comprises a voltage adjusting means 31 for outputting.
