Abstract
본 발명은 복수 채널의 방송신호를 동시에 녹화하여 사용자가 원하는 채널의 화면을 재생할 수 있는 2화면 VCR에 관한 것으로서, 사용자가 선호하는 프로그램이 같은 시간대에 2개 이상 동시 방송되는 경우 사용자가 원하는 방송신호를 놓치는 일을 방지하기 위한 것이다. 이를 위하여 본 발명은 안테나를 통해 수신되는 고주파 신호를 복수개의 튜너로 각각 입력되게 분배하는 분배수단; 상기 분배수단에서 분배된 고주파 신호로부터 원하는 채널을 각각 선택하는 복수개의 주파수 동조수단; 상기 각각의 주파수 동조수단을 통해 선택된 방송신호로부터 영상신호를 검출하여 출력처리하는 복수개의 영상 IF검출 및 처리수단; 상기 각각의 주파수 동조수단을 통해 선택된 방송신호로부터 음성신호를 검출하여 처리하는 복수개의 음성 IF검출 및 처리수단; 상기 복수개의 영상 처리수단에서 출력되는 각각의 영상신호(또는 테이프 재생신호)를 2화면 동시 출력이나 녹화를 위해 동기신호에 따라 분리되고 재조합하는 영상 조합수단; 상기 복수개의 음성 처리수단에서 출력되는 각각의 음성신호(또는 테이프 재생신호)를 L채널 또는 R채널 모노로 나누어 녹음하고 재조합하는 음성조합수단; 상기 영상 조합수단에서 공급되는 신호를 테이프에 기록하거나 테이프에 기록된 신호를 재셍하여 소정 레벨 증폭하는 영상 기록/재생수단; 상기 음성 조합수단에서 공급되는 신호를 테이프에 기록하거나 테이프에 기록된 신호를 재생하여 소정 레벨 증폭하는 음성 기록/재생수단으로 구성함을 특징으로 한다.[0001] The present invention relates to a two-screen VCR capable of simultaneously recording a plurality of channels of broadcast signals and reproducing a screen of a desired channel. When two or more programs are simultaneously broadcasted in the same time zone, In order to prevent missed operations. To this end, according to the present invention, there is provided a radio communication system comprising: distributing means for distributing a high frequency signal received through an antenna to be input to a plurality of tuners, respectively; A plurality of frequency tuning means for respectively selecting a desired channel from the high frequency signals distributed by the distributing means; A plurality of image IF detection and processing means for detecting and outputting a video signal from a broadcasting signal selected through the respective frequency tuning means; A plurality of audio IF detection and processing means for detecting and processing a voice signal from a broadcast signal selected through the respective frequency tuning means; Video combining means for separating and recombining each video signal (or a tape reproducing signal) output from the plurality of video processing means according to a synchronizing signal for simultaneous two-screen output or recording; Audio combining means for separately recording and recombining respective audio signals (or tape reproduction signals) output from the plurality of audio processing means into an L channel or R channel mono; An image recording / reproducing means for recording a signal supplied from the image combining means on a tape, or reproducing a signal recorded on the tape to amplify the signal by a predetermined level; And an audio recording / reproducing means for recording a signal supplied from the audio combining means on a tape or reproducing a signal recorded on a tape to amplify the signal to a predetermined level.
