Abstract
본 발명은 2-튜너 텔레비전의 채널제어장치에 관한 것으로, 방송국으로부터 전송되는 방송신호에 포함된 파일럿신호를 기초로 음성다중 또는 스테레오, 모노모드에 의한 방송신호의 선택적인 시청이 가능하도록 제1 및 제2튜너(18a,18b)와, 최소한 어느 하나의 튜너에서 선국된 방송신호를 중간주파수에 의해 처리하는 IF모듈(20), 이 IF모듈(20)에서 처리된 방송신호의 영상신호를 처리하여 재생되도록 하는 영상신호처리부(22)와 상기 IF모듈(20)에서 처리된 음성 신호를 음성다중처리하는 음성다중처리부(26)를 갖추어 구성된 2-튜너 텔레비전에서, 해당 텔레비전에 대한 상기 모드의 선택과 그 선택된 모드의 지속적인 수신을 위한 모드지정입력이 가능한 기능제어부(10)와, 그 기능제어부(10)에서 입력되는 모드에 따라 상기 제1 및 제2튜너(18a,18b)를 제어하여 상기 선택된 모드에 의한 방송신호의 수신과 상기 지정된 모드의 방송신호를 수신하기 위한 채널절환을 행하는 제어부(12), 상기 모드지정상태에서 최소한 어느 하나의 튜너에 의해 그 지정된 모드의 파일럿신호를 검출하는 파일러신호검출부(30)를 포함하여 구성된 것이다.The present invention relates to a channel control apparatus for a two-tuner television. The present invention relates to a channel control apparatus of a two-tuner television. The present invention relates to a channel control apparatus of a two-tuner television. An IF module 20 which processes the second tuner 18a, 18b and the broadcast signal tuned in at least one tuner by an intermediate frequency, and processes the video signal of the broadcast signal processed by the IF module 20 In a two-tuner television comprising a video signal processor 22 for reproducing and an audio multiple processor 26 for audio multiplexing the audio signal processed by the IF module 20, selection of the mode for the television and A function control unit 10 capable of specifying a mode for continuous reception of the selected mode and the first and second tuners 18a and 18b are controlled according to the mode input from the function control unit 10. A control unit 12 which performs channel switching for receiving the broadcast signal in the selected mode and receiving the broadcast signal in the designated mode, and detects the pilot signal in the designated mode by at least one tuner in the mode designation state; The filer signal detector 30 is configured to be included.
