픽쳐 인 픽쳐 텔레비젼 수상기와 비디오 테이프 기록/재생 시스템에 있어서, 리모콤 신호 입력을 받으며 시스템을 제어하는 마이컴(10)과, 상기 마이컴(10)으로부터 제어신호를 받아 동작하며 입력된 음성 및 영상 반송파의 희망 주파수를 선택함과 동시에 증폭하여 감도를 높이고 신호 대 잡음비를 개선하며 신호 주파수를 중간 주파수로 변환시켜 출력하는 제1 및 제2튜너(30, 40)와, 상기 마이컴(10)으로부터 발생되는 오디오 출력제어신호에 따라 상기 제1 및 제2튜너(30, 40)로부터 출력되는 오디오 신호중 선택된 채널에 해당하는 오디오 신호를 출력하는 오디오 선택부(60)와, 상기 제1 및 제2튜너(30, 40)로부터 각 채널의 비디오 신호를 입력하여 상기 마이컴(10)의 제어에 따라 픽쳐 인 픽쳐기능을 수행하는 pip부(20)와, 채널선택에 따라 상기 마이컴(10)으로부터 발생되는 튜너 컴트롤 신호를 받아 제1 혹은 제2튜너(30, 40) 출력 측에서 얻어지는 영상 및 음성 중간 주파수가 일정 주파수 대역에 존재할 수 있도록 하는 국부 발진주파수의 파인튜닝 수행 상태를 마이컴(10)이 감지토록 하는 아날로그 스위치부(50)으로 구성됨을 특징을 하는 멀티채널 스캐닝시 소화면 채널의 음성 선택장치.In a picture-in-picture television receiver and a video tape recording / reproducing system, a microcomputer 10 that receives a remote control signal and controls a system, and receives a control signal from the microcomputer 10 and operates an audio and video carrier. The first and second tuners 30 and 40 and the audio generated from the microcomputer 10 select the desired frequency and amplify the signal to increase the sensitivity, improve the signal-to-noise ratio, and convert the signal frequency into an intermediate frequency. An audio selector 60 for outputting an audio signal corresponding to a selected channel among audio signals output from the first and second tuners 30 and 40 according to an output control signal, and the first and second tuners 30, A pip unit 20 which inputs a video signal of each channel from the channel 40 to perform a picture in picture function under the control of the microcomputer 10, and the microcomputer 10 according to channel selection. The microcomputer 10 receives a fine tuning state of the local oscillation frequency to receive the generated tuner control signal so that the video and audio intermediate frequencies obtained at the output side of the first or second tuner 30 or 40 can exist in a predetermined frequency band. The voice selection device of the small screen channel during multi-channel scanning, characterized in that it consists of an analog switch unit 50 for sensing. 픽쳐 인 픽쳐 텔레비젼 수상기와 비디오 테이프 기록/재생 시템에 있어서, 멀티 채널 스캐닝 수행중 새로운 음성 선택 키입력 여부를 조사하는 제1과정과, 음성 선택 키 입력이 없을시 음성 선택 카운터 값 “0”에 대응하는 채널을 선국하는 제2과정과, 음성 선택 키 입력이 있을시 음성 선택 카운터 값을 “1”증가시키고 상기 증가된 카운터 값이 “자화면수+1”과 동일한지 비교하는 제3과정과, 상기 증가된 카운터 값이 자화면수+1과 동일할시 음성 선택 카운터 값을 클리어시키고 해당 카운터 값에 대응하는 자화면과 동일한 채널을 선국하고 종료하는 제4과정과, 상기 증가된 음성 선택 카운터 값이 자화면수+1과 같지 않을시 상기 카운터 값에 대응하는 자화면과 동일한 채널을 선국하고 종료하는 제5과정으로 이루어짐을 특징으로 하는 멀티 채널 스캐닝시 소화면 채널의 음성 선택방법.In a picture-in-picture television receiver and videotape recording / playback system, a first process of checking whether a new voice selection key is pressed during multi-channel scanning and a voice selection counter value "0" when no voice selection key is input A second process of tuning a channel to be performed, a third process of increasing a voice selection counter value by "1" when there is a voice selection key input and comparing whether the increased counter value is equal to "number of screens + 1"; A fourth step of clearing a voice selection counter value when the incremented counter value is equal to the number of own screens + 1 and selecting and terminating the same channel as the own screen corresponding to the counter value; And a fifth process of selecting and terminating the same channel as the subscreen corresponding to the counter value when the subscreen number is not equal to +1.
