Abstract

본 발명은 부화면모드선택시 주튜너에 의해 선국되어 영상처리부에 의해 영상처리되는 주화면에 대한 영상출력신호와 보조튜너에 의해 선국되어 부화면처리부에 의해 처리되는 부화면에 대한 영상출력신호를 마이콤제어수단의 제어에 따라 합성하여 주화면에 부화면이 포함되는 영상을 외부영상기기로 출력할 수 있도록 한 부화면 출력기능을 갖춘 텔레비전을 제공한다.According to the present invention, when the sub picture mode is selected, an image output signal for the main picture selected by the main tuner and processed by the image processor and an image output signal for the sub picture selected by the sub-tuner and processed by the sub picture processing unit. According to the control of the microcomputer control means to provide a television with a sub-screen output function that can be output to the external video device the image including the sub-screen on the main screen.

이를 위해 본 발명은, 주튜너(21)와 보조튜너(30)로 이루어져 별개의 방송채널을 선국할 수 있도록 된 튜너부와, 상기 주튜너(21) 및 보조튜너(30)로부터의 중간주파수를 각각 증폭처리하여 복합영상신호 및 음성신호를 출력하는 제1 및 제2중간주파증폭부(22,31) 및, 상기 제2중간주파증폭부(31)로부터의 복합영상 신호를 처리하기 위한 부화면처리부(40)를 갖추어 키입력부(80)로부터의 부화면 기능 선택시 CRT(24)의 스크린상에 주화면을 디스플레이함과 동시에 상기 CRT(24) 스크린상의 소정의 위치에 부화면을 디스플레이할 수 있도록 된 부화면 모드를 갖춘 텔레비젼에 있어서, 상기 부화면모드선택시 영상처리부(23)로부터의 주화면에 대한 영상출력신호와 부화면처리부(40)로부터의 부화면에 대한 영상출력신호를 마이콤(50)으로부터 출력되는 부화면 위치 제어신호에 따라 합성하여 외부기기접속부(70)로 출력가능한 혼합부(60)를 더 구비하여 구성된다.To this end, the present invention comprises a tuner unit consisting of a main tuner 21 and an auxiliary tuner 30 to tune to a separate broadcast channel, and an intermediate frequency from the main tuner 21 and the auxiliary tuner 30. Sub-screens for processing the composite video signals from the first and second intermediate frequency amplifiers 22 and 31 and the second intermediate frequency amplifier 31 for amplifying and outputting a composite video signal and an audio signal, respectively. The processing unit 40 can display the main screen on the screen of the CRT 24 and the sub screen at a predetermined position on the screen of the CRT 24 when the sub screen function is selected from the key input unit 80. In a television equipped with a sub picture mode, the video output signal for the main picture from the image processing unit 23 and the video output signal for the sub picture from the sub picture processing unit 40 are selected when the sub picture mode is selected. Sub-screen position output from 50) Synthesized according to a signal comprises the further possible output to an external device connector 70, the mixing section 60.
