Abstract

본 발명은 텔레비전 수상기등에 있어서 주파수 합성방식의 전자튜너를 사용하여 기저장된 방송채널을 선국하거나 프리세트장치에 의한 방송채널의 선국을 사용자의 선택에 따라 사용할 수 있는 튜닝장치에 관한 것이다. 본 발명의 장치는 사용자가 수신지역의 방송주파수군을 선택하고, 리얼채널과 프로그램채널을 선택하는 키입력부와 프리세트된 국부발진주파수신호 및 각 주파수군별로 국부발진주파수신호를 기억하고 있는 저장부와 국부발진주파수신호에 따른 튜닝신호를 발생하는 제어부와 튜닝신호에 근거한 방송주파수를 선국하는 튜너를 구성한다. 따라서, 본 발명은 주파수합성방식의 전자튜너를 사용하여 같은 전파대역의 텔레비전 방송을 리얼채널 번호에 의하여 선국할 수 있으며, 또한 프로그램채널번호에 의하여 수신할 수 있다.The present invention relates to a tuning device that can tune a pre-stored broadcast channel using a frequency synthesizer electronic tuner in a television receiver or the like, and select a broadcast channel by a preset device according to a user's selection. According to an embodiment of the present invention, a user selects a broadcast frequency group in a reception area, stores a key input unit for selecting a real channel and a program channel, a preset local oscillation frequency signal, and a local oscillation frequency signal for each frequency group. And a control unit for generating a tuning signal according to the local oscillation frequency signal and a tuner for tuning a broadcasting frequency based on the tuning signal. Therefore, according to the present invention, television broadcasting of the same radio band can be tuned by real channel number and received by program channel number using an electronic tuner of frequency synthesis method.
