Abstract

본 발명은 고화질 텔레비젼(HDTV)의 수신과 일반 텔레비젼의 수신을 공용으로 사용하는 텔레비젼의 공용수신장치에 관한 것으로, 이를 해결하기 위해 선국회로의 제어신호에 의해 동작되어 입력단에서 입력되는 신호의 통로를 스위칭 제어하는 제1통로제어부; 제1통로제어부의 스위칭동작에 의해 고화질 방식이 선택될 경우 입력단을 통해 인가되는 영상신호를 고화질 방식으로 신호를 처리하는 고화질 처리부; 제1통로제어부의 스위칭동작에 의해 NTSC 방식이 선택될 경우 입력단을 통해 인가되는 영상신호를 NTSC 방식으로 신호를 처리하는 NTSC 방식 처리부; 선국회로의 제어신호에 의해 고화질 방식이 선택될때 고화질 처리부에서 처리된 신호가 디지탈 복조 IC로 전달되도록 통로를 제어하고, 선국회로의 제어신호에 의해 NTSC 방식이 선택될때 NTSC 방식 처리부에서 처리된 신호가 NTSC 복조 IC로 전달되도록 통로를 제어하는 제2통로제어부를 포함하도록 구성된다.The present invention relates to a common receiving apparatus of a television which uses a reception of a high-definition television (HDTV) and a reception of a general television in common. A first passage controller for controlling switching; A high quality processor configured to process a video signal applied through an input terminal in a high quality manner when a high quality type is selected by a switching operation of the first path controller; An NTSC processing unit configured to process an image signal applied through an input terminal in an NTSC method when an NTSC method is selected by a switching operation of the first path controller; When the high quality method is selected by the control signal of the tuning circuit, the signal is processed by the high quality processing unit so that the signal is transferred to the digital demodulation IC. When the NTSC method is selected by the control signal of the tuning circuit, the signal processed by the NTSC processing unit is And a second path controller for controlling the path to be delivered to the NTSC demodulation IC.
