Abstract

본 발명은 음성다중방송이 가능한 텔레비젼에 있어서 사용자에 의해 영화 화면비로의 절환요구가 있을 경우 음성다중신호의 검출여부에 따라 현재 화면의 수직폭만을 축소조절시켜 줌으로써 영화감상의 효과를 얻을수 있도록 한 텔레비젼의 수직화면폭 제어장치를 제공하기 위한 것이다.According to the present invention, when a user needs to switch to a movie aspect ratio in a television capable of multiplexing voice, the effect of watching a movie can be obtained by reducing only the vertical width of the current screen according to whether the multiplex signal is detected. It is to provide a vertical screen width control device.

이를 위해 본 발명은, 음성다중방송이 가능한 텔레비젼에서 영화화면비로의 절환을 요구하는 영화화면모드설정용 키(12a)를 갖춘 키입력부(12)와 주음성채널 및 부음성채널에 각각 대응되게 설치되어 주음성채널 및 상기 부음성채널로부터 전송되는 음성신호의 유무를 감지하는 제1 및 제2신호감지부(14. 16), 상기 제1 및 제2신호감지부(14. 16)로부터의 출력신호를 입력받아 논리처리하는 논리소자(18), 상기 키입력부(12)에서 영화화면모드가 설정되면 상기 제1 및 제2신호감지부(14. 16)의 동작이 행해지도록 제어함과 더불어 상기 논리소자(18)의 결과치를 기초로 현재 디스플레이되는 화면에 대한 소정의 수직폭조절제어신호를 출력하는 마이컴(20) 및, 상기 마이컴(20)의 제어하에 수직출력회로부(24)의 수직출력전압을 제어하는 수직출력전압제어부(22)로 구성되고, 상기 논리소자(18)는 앤드게이트로 이루어진 것이다.To this end, the present invention is installed so as to correspond to the key input section 12, the main audio channel and the sub-audio channel, each having a movie screen mode setting key 12a for requesting switching from a television capable of voice multicast to a movie aspect ratio. Output from the first and second signal detectors (14.16) and the first and second signal detectors (14.16) for detecting the presence or absence of a voice signal transmitted from the main audio channel and the sub-audio channel. When the motion picture mode is set by the logic element 18 and the key input unit 12 that receive and process a signal, the operation of the first and second signal detection units 14. 16 is controlled. The microcomputer 20 for outputting a predetermined vertical width adjustment control signal for the currently displayed screen based on the result of the logic element 18, and the vertical output voltage of the vertical output circuit unit 24 under the control of the microcomputer 20. It consists of a vertical output voltage control unit 22 for controlling the The logic element 18 is composed of an end gate.
