Abstract

본 발명은 반블랭킹모드를 설정하는 경우에 OSD표시가능한 모든 표시항목에 따른 문자정보와 그래픽정보가 반블랭킹되어 화면표시될 수 있도록 하는 텔레비전의 전체 OSD표시정보 반블랭킹장치를 제공한다.The present invention provides a full OSD display information anti-blanking device of a television which allows text information and graphic information according to all display items that can be displayed on an OSD to be semi-blanked and displayed on the screen when the half-blanking mode is set.

그에 따라 본 발명은 튜너(4)에 의해 선국된 소정 채널의 영상신호가 영상IF부(6)를 통해 중간주파증폭되고 영상처리수단(8,10)에 의해 영상처리되어 영상출력구동부(28)를 통해 영상재생되는 텔레비전에 있어서; 전체적인 기능메뉴를 화면표시하는 표시항목의 표시정보에 대한 반블랭킹모드를 키설정하는 기능설정수단(2)과, 상기 영상처리수단(8,10)의 영상신호에서 수직/수평동기신호를 분리하여 추출하는 수직/수평동기추출수단(12,14,16), 상기 기능설정수단(2)에 의한 반블랭킹모드의 설정에 의해 상기 추출되는 수직/수평동기신호에 의거하여 전체적인 기능메뉴의 표시항목에 대한 반블랭킹표시가 이루어지도록 제어하는 제어수단(18), 상기제어수단(18)의 제어하에 전체적인 기능메뉴에 대한 표시항목의 표시정보를 생성하는 표시신호발생수단(20,22), 상기 수직/수평동기추출수단(12,14,16)으로부터의 수직/수평동기신호에 의거하여 상기 표시정보신호의 표시위치를 지정하는 표시위치지정수단(24) 및, 상기 제어수단(18)의 제어하에 상기 표시위치가 지정된 표시정보신호에 대해서 반블랭킹되도록 고속으로 스위칭되는 고속스위치수단(26)을 구비하여 구성된 것을 특징으로 한다.Accordingly, in the present invention, an image signal of a predetermined channel tuned by the tuner 4 is amplified by an intermediate frequency through the image IF unit 6 and image processed by the image processing means 8 and 10 to output an image output driver 28. A television which is reproduced by video; Function setting means (2) for key setting the anti-blanking mode for the display information of the display item for displaying the overall function menu, and separating the vertical / horizontal synchronization signal from the image signal of the image processing means (8, 10) Based on the vertical / horizontal synchronous extraction means 12, 14 and 16 to be extracted and the anti-blanking mode set by the function setting means 2, the display items of the overall function menu Control means 18 for controlling the anti-blanking display for the display, display signal generating means 20 and 22 for generating display information of the display items for the entire function menu under the control of the control means 18, and the vertical / Display position designating means (24) for designating a display position of the display information signal on the basis of the vertical / horizontal synchronizing signal from the horizontal synchronizing extracting means (12, 14, 16) and the control means (18). Display designated with display position And a high speed switch means 26 which is switched at a high speed so as to be semi-blanked with respect to the complementary signal.
