Abstract

본 발명은 방송국에서 전송되는 외화를 TV로 시청시 TV화면 상, 하에 나타나는 흑대부분을 제거하고 자막을 화면하부에 표시하여 시청효과를 배가시키기 위한 자막이동시스템에 관한 것으로, 메모리부(6)에 저장된 데이타를 마이컴(9)의 제어에 의해 판독하여 자막이 있다고 판단시 메모리부(8)에 저장된 특정(자막) 라인의 휘도(Y) 신호를 영상처리하고 마이컴(9)이 수직 편향제어부(l4)를 통해 흑대부분을 제거하고 자막에 대한 데이타를 편향요크(DY)의 조정에 의해 화면하부에 자막을 표시하여 영상을 TV화면에 꽉 차게하여 보다 안정된 외화를 시청할 수 있도록 한 것이다.The present invention relates to a subtitle moving system for doubling the viewing effect by removing black bars appearing on the top and bottom of a TV screen when viewing foreign currency transmitted from a broadcasting station on a TV, and displaying subtitles at the bottom of the screen. When the stored data is read under the control of the microcomputer 9 and judges that there is a subtitle, the microcomputer 9 performs image processing on the luminance (Y) signal of a specific (subtitle) line stored in the memory unit 8, and the microcomputer 9 performs a vertical deflection control unit l4. ), The black band is removed, and the subtitle data is displayed on the lower part of the screen by adjusting the deflection yoke (DY) to fill the video on the TV screen for more stable foreign currency viewing.
