Abstract
본 발명은 문자다중방송기능을 구비한 텔레비젼에 있어서 문자다중신호의 휘도조절이 가능한 텔레비젼에 관한 것으로, 보다 상세하게 텔레비젼 화면이 한개 영상프레임내에 포함된 캡션화면이 휘도를 개별분리조정할 수 있는 텔레비젼에 관한 것이다.The present invention relates to a television capable of adjusting the luminance of a text signal in a television having a teletext function. More specifically, a caption screen in which a television screen is included in one video frame is used for a television .
정류프로그램의 RF방송신호와 문자정보신호로 구성된 복합영상신호를 선국하여 중간주파수형태로 변환시키는 튜너부(10)와, 선국된 영상신호를 분리검파하고 영상중간주파증폭하는 영상 IF부(20)와, 영상신호로 부터 잡음등을 제거하는 영상검파부(30)와, 상기 영상검파부(30)와, 상기 영상검파부(30)를 거쳐 검파된 영상신호로 부터 수평동기신호 및 수직 동기신호를 분리해내기 위한 동기분리부(40)와, 복합영상신호에서 문자정보신호를 추출해내기 위한 캡션정보신호추출부(51) 및 사용자가 선택한 문자정보 일부분을 아날로그 R,G,B신호로 변환출력시키기 위한 캡션화면디스플레이부(52)를 포함하는 캡션디코더(50)와, 텔레비젼의 제반기능 및 캡션기능제어를 담당하는 제어부(60)와, 문자다중방송으로 제공되는 정보가운데 사용자가 선택한 정보페이지를 저장하는 메모리장치(70)와, 상기 영상검파부(30)를 통하여 검파된 영상신호를 증폭 및 처리하는 영상증폭 및 처리부(80)와, 상기 영상증폭 및 처리부(8)로부터 제공되는 R,G,B영상신호 및 상기 캡션화면 디스플레이브(52)로부터 제공되는 R,G,B아날로그신호를 영상재생가능하게 출력시키는 영상출력구동부(90)와, 영상출력을 담당하는 수상기(100)를 포함하는 텔레비젼에 있어서, 상기 제어부(60)가 상기 캡션디코더(50)의 캡션화면디스플레이부(52)에 휘도레벨조정신호를 인가하고 상기 캡션화면 디스플레이부(52)가 상기 제어신호에 응답하여 휘도레벨조정된 RGB아날로그출력신호를 영상출력신호로서 제공함과 더불어 또한 상기 제어부(60)가 상기 영상증폭 및 처리부(80)에 휘도레벨조정신호를 포함한 제어신호를 인가하여 영상출력신호를 발생시키는 것을 특징으로 하는 캡션신호의 휘도레벨분리조정 기능을 구비한 텔레비전이다.A tuner section 10 for tuning a composite video signal composed of a RF broadcast signal and a character information signal of a rectifying program and converting the mixed video signal into an intermediate frequency form, an image IF section 20 for separately detecting and interfacing a selected video signal, A video detector 30 for removing noise or the like from the video signal, a horizontal synchronizing signal and a vertical synchronizing signal from the video signal detected through the video detector 30 and the video detector 30, A caption information signal extracting unit 51 for extracting a character information signal from the composite video signal, and a caption information extracting unit 51 for converting a part of the character information selected by the user into analog R, G, B signals A control unit 60 for controlling various functions of the television and a caption function, and an information page selected by the user from the information provided by the teletext broadcasting. The caption decoder 50 includes a caption screen display unit 52,An image amplification and processing unit 80 for amplifying and processing the image signal detected through the image detection unit 30 and an image amplification and processing unit 80 for R and G A video output driver 90 for outputting a B video signal and R, G, and B analog signals provided from the caption screen display 52 in a reproducible manner, and a receiver 100 for video output, In the television, the control unit 60 applies a brightness level adjusting signal to the caption screen display unit 52 of the caption decoder 50, and the caption screen display unit 52 adjusts the brightness level in response to the control signal And the control unit 60 applies a control signal including a brightness level adjustment signal to the image amplification and processing unit 80 to generate a video output signal A television is provided with a separate brightness level adjustment function of the caption signal to.
