원격음량조절의 TV 채널선택시스템TV channel selection system with remote volume control

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제3도는 본 발명에 의한 원격음량조절의 TV 채널선택시스템.3 is a TV channel selection system for remote volume control according to the present invention.

Claims (1)

가변발진기 및 제1,2믹서기(32,34), 고정발진기(33), 밴드패스필터(36)등을 포함한 튜너(A)와 음성 및 영상 신호계통을 분리처리하여 음량조절이 가능케 되는 유선 TV등의 컨버터 회로에 있어서, 상기 튜너(A)의 제1믹서기(32)측 발진기는 전압제어발진기(31)로 되고, 이 전압제어발진기(31)와 마이크로프로세서(13)와의 신호합성기(21) 일단으로 이어지고, 그 출력측 또 다른 경로는 리미터(15), 고정발진기(17)가 포함된 믹서기(16), 여파기(18), 증폭기(19)를 차례로 거쳐 음성검파 IC(23)의 일단으로 연결되며, 상기 음성검파 IC(23)의 타단은 마이크로프로세서(13)의 볼륨제어단과 연결된 음량조절기(24)가 연결되고 상기 음성검파 IC(23)의 출력은 RF 변조기(22)를 거쳐 상기 신호합성기(21)측으로 연결되어지는 관련구성을 특징으로 하는 원격음량 조절의 TV 채널선택시스템.Tuner A including variable oscillator and first and second mixers 32 and 34, fixed oscillator 33, and band pass filter 36 and audio and video signal systems are separately processed to enable volume control. In the converter circuit of the present invention, the first mixer 32 side oscillator of the tuner A is a voltage controlled oscillator 31, and the signal synthesizer 21 of the voltage controlled oscillator 31 and the microprocessor 13 is used. One path of the output side is connected to one end of the voice detection IC 23 through the limiter 15, the mixer 16 including the fixed oscillator 17, the filter 18, and the amplifier 19 in order. The other end of the voice detector IC 23 is connected to a volume controller 24 connected to the volume control stage of the microprocessor 13, and the output of the voice detector IC 23 is passed through the RF modulator 22 to the signal synthesizer. A TV channel selection system for remote volume control, characterized in that the associated configuration is connected to the (21) side. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임※ Note: The disclosure is based on the initial application.
