Abstract

본 발명은 위성방송 및 무선케이블 TV의 수신기에 관한 것으로서, 특히 위성방송모드와 무선 케이블 TV모드를 겸용으로 수신하여 EPG(Electronic Program Guide)기능을 수행할 수 있도록 한 위성방송과 무선케이블 TV의 공동 수신기에 관한 것이다.The present invention relates to a receiver for satellite broadcasting and wireless cable TV, and in particular, a satellite broadcasting and a wireless cable TV jointly receiving both a satellite broadcasting mode and a wireless cable TV mode to perform an EPG (Electronic Program Guide) function. To a receiver.

상기와 같은 목적을 달성하기 위한 본 발명은 위성방송모드신호를 수신하는 위성방송 수신안테나와, 무선케이블 TV모드신호를 수신하는 무선 케이블 TV수신안테나와, 상기 위성방송모드신호와 무선 케이블 TV모드신호의 높은 주파수를 일정 주파수로 가변시키는 제1 및 제2주파수변환부와, 일정 주파수로 가변된 상기 위성 방송모드신호와 무선 케이블 TV모드신호를 복수개의 제어신호에 의해 단일 프로그램으로 분리하여 EPG데이타의 OSD문자신호가 혼합된 영상신호를 출력하는 신호분리 및 처리수단과, 상기 신호분리 및 처리수단의 출력신호를 받아 시청 가능하게 하는 디스플레이부로 이루어짐을 특징으로 한다.The present invention for achieving the above object is a satellite broadcast reception antenna for receiving a satellite broadcast mode signal, a wireless cable TV reception antenna for receiving a wireless cable TV mode signal, the satellite broadcast mode signal and a wireless cable TV mode signal A first program and a second frequency converter for varying a high frequency of a predetermined frequency; and the satellite broadcast mode signal and a wireless cable TV mode signal, which are variable at a predetermined frequency, are separated into a single program by a plurality of control signals. Signal separation and processing means for outputting a video signal mixed with the OSD text signal, and a display unit for receiving and viewing the output signal of the signal separation and processing means.

따라서, 본 발명에 따른 위성방송과 무선케이블 TV의 공동수신기는 두가지 방송모드를 동시에 수신할 수 있도록 한 장치이기에 사용자 서비스의 편리성 및 제작비용을 낮출 수 있는 효과가 있다.Therefore, the satellite receiver and the co-receiver of the wireless cable TV according to the present invention have the effect of reducing the convenience and production cost of the user service because it is a device that can receive two broadcast modes at the same time.
