Abstract

본 발명은 CRT의 스크린상에 디스플레이되는 영상은 주튜너에 의해 선국된 방송프로그램에 대한 영상이 소정의 영상처리과정을 거쳐 디스플레이되고, 스피커를 통해 출력되는 음성은 부화면모드가 선택되지 않았더라도 보조튜너에 의해 선국된 다른 방송프로그램에 대한 음성이 소정의 음성처리과정을 거쳐 출력되도록 된 영상/음성개별수신기능을 갖춘 텔레비젼을 제공한다.According to the present invention, an image displayed on a screen of a CRT is displayed through a predetermined image processing process for a broadcast program tuned by a main tuner, and an audio output through a speaker is subsidiary even if a sub picture mode is not selected. Provided is a television having a video / audio individual reception function in which audio for another broadcast program tuned by a tuner is output through a predetermined audio processing process.

이를 위해 본 발명은, 주튜너(12)와 보조튜너(20)로 이루어져 별개의 방송채널을 선국할 수 있도록 된 튜너부와, 상기 주튜너(12) 및 보조튜너(20)로부터의 중간주파수를 각각 증폭처리하여 복합영상신호 및 음성신호를 출력하는 제1 및 제2중간주파증폭부(13,21) 및, 상기 제2중간주파증폭부(21)로부터의 복합영상신호를 처리하기 위한 부화면처리부(22)를 갖추어 키입력부(60)로부터의 부화면 기능 선택시 CRT부(15)의 스크린상에 주화면을 디스플레이함과 동시에 상기 CRT부(15)의 스크린상의 소정의 위치에 부화면을 디스플레이할 수 있도록 된 부화면 기능을 갖춘 텔레비젼에 있어서, 기존의 기능키외에 영상/음성개별수신모드키를 더 갖춘 키입력부(60)와, 그 각각의 입력단자가 상기 제1 및 제2중간주파증폭부(13,21)의 음성신호출력단에 접속되고 그 출력단자가 음성처리부(40)의 입력단에 접속된 음성신호자동절환스위칭부(30) 및, 상기 키입력부(60)로부터 영상/음성개별수신모드키가 선택됨에 따라 활성화되어 상기 부화면처리부(22) 및 음성신호자동절환스위칭부(30)로 소정의 제어신호를 송출하여 상기 부화면처리부(22)의 기능을 정지시킴과 더불어 상기 음성신호자동절환스위칭부(30)를 스위칭절환하는 영상/음성개별수신기능을 갖춘 마이콤(50)을 더 구비하여 구성된다.To this end, the present invention, the tuner unit consisting of the main tuner 12 and the auxiliary tuner 20 to tune to a separate broadcast channel, and the intermediate frequency from the main tuner 12 and the auxiliary tuner 20 Sub-screens for processing the composite video signals from the first and second intermediate frequency amplifiers 13 and 21 and the second intermediate frequency amplifier 21 for amplifying and outputting a composite video signal and an audio signal, respectively. The processing unit 22 displays the main screen on the screen of the CRT unit 15 when the sub-screen function is selected from the key input unit 60, and simultaneously displays the sub-screen at a predetermined position on the screen of the CRT unit 15. In a television having a sub-screen function that can be displayed, the key input unit 60 further includes a video / audio individual reception mode key in addition to the existing function keys, and each of the input terminals has the first and second intermediate frequencies. Connected to the audio signal output terminals of the amplifiers 13 and 21, and its output terminals The audio signal automatic switching switching unit 30 connected to the input of the audio processing unit 40 and the video / audio individual receiving mode key are selected from the key input unit 60 to activate the sub-screen processing unit 22 and the audio. A video / audio individual receiving function for sending a predetermined control signal to the signal automatic switching switching unit 30 to stop the function of the sub picture processing unit 22 and switching the audio signal automatic switching switching unit 30. It is configured to further comprise a microcomputer 50 equipped with.

Description
