Abstract
본 발명은 하나의 테이프에 두개 채널의 영상 신호를 동시에 기록하며, 기록된 두개 채널의 영상 신호중 원하는 채널의 영상 신호를 선택하여 디스플레이 할 수 있도록 하는 비데오 카세트 레코더에 관한 것으로서, 사용자의 제어에 따른 튜닝 전압 및 1필드에 해당하는 시간 주기를 두고, 제1, 제2 및 제3스위칭 신호와 기록 및 독출 신호를 순차적으로 출력하는 제어부와; 튜닝 전압에 따른 방송 채널의 영상 신호를 수신하는 제1, 제2튜너와; 제1스위칭 신호에 따라 스위칭되어 제1, 제2튜너의 영상 신호를 선택적으로 출력하는 제1스위칭부와; 기록 및 독출 신호에 따라 1필드에 해당하는 제1스위칭부의 영상 신호를 선택적으로 저장 및 독출하는 제1저장 회로와; 제1스위칭 신호에 따라 스위칭되어 제1스위칭부에서 출력되지 않는 제1 또는 제2튜너의 영상신호를 선택적으로 출력하는 제2스위칭부와; 제2스위칭 신호에 따라 스위칭되어 저장회로 또는 제2스위칭부의 영상 신호를 선택적으로 출력하는 제3스위칭부와; 제3스위칭부의 영상 신호를 기록 처리하여 출력하는 영상 기록계와; 녹화 모드에 영상 기록계에서 처리된 영상 신호를 자기 테이프에 기록하며, 재생 모드시에 자기테이프에 기록된 영상 신호를 독출하여 출력하는 데크와; 데크에 의하여 독출된 영상 신호를 재생 처리하여 출력하는 영상 재생계와; 기록 및 독출 신호에 따라 영상 재생계의 영상 신호에서 1필드에 해당하는 영상 신호를 기록 및 저장하는 제2저장 회로와; 제3스위칭 신호에 따라 제2저장 회로 또는 영상 재생계의 영상 신호를 선택적으로 출력하는 제3스위칭부를 포함한다.The present invention relates to a video cassette recorder for simultaneously recording two channels of video signals on one tape, and selecting and displaying a video signal of a desired channel among two recorded video signals. A controller for sequentially outputting the first, second and third switching signals and the write and read signals at time periods corresponding to the voltage and one field; First and second tuners for receiving an image signal of a broadcast channel according to a tuning voltage; A first switching unit which is switched according to the first switching signal and selectively outputs image signals of the first and second tuners; A first storage circuit for selectively storing and reading the video signal of the first switching unit corresponding to one field according to the recording and reading signals; A second switching unit for selectively outputting an image signal of a first or second tuner which is switched according to the first switching signal and is not output from the first switching unit; A third switching unit which is switched according to the second switching signal and selectively outputs an image signal of the storage circuit or the second switching unit; A video recorder which records and processes the video signal of the third switching unit; A deck for recording a video signal processed by a video recorder in a recording mode on a magnetic tape, and reading and outputting a video signal recorded on the magnetic tape in a playback mode; A video reproducing system for reproducing and outputting a video signal read by the deck; A second storage circuit for recording and storing a video signal corresponding to one field in the video signal of the video reproducing system according to the recording and reading signals; And a third switching unit for selectively outputting a video signal of a second storage circuit or a video reproducing system according to the third switching signal.
즉, 본 발명은 상술한 바와 같이 우수 또는 기수 필드에 해당하는 두개의 방송 채널의 영상 신호를 자기 테이프에 순차적으로 기록하고, 재생시에는 선택된 방송 채널의 1필드에 해당하는 영상 신호를 2회에 결쳐 모니터에 디스플레이하므로써 1프레임을 형성하게 하는 것이다.That is, the present invention sequentially records the video signals of two broadcast channels corresponding to the even or odd field on the magnetic tape as described above, and during playback, the video signals corresponding to one field of the selected broadcast channel are combined twice. By displaying on the monitor, one frame is formed.
따라서, 본 발명은 하나의 자기 테이프로서 두개 방송 채널의 영상 신호를 동시에 녹화하여 재생할 수 있어 동 시간대에 기록하고자하는 방송 채널이 두개 이상인 경우에 매우 유용하다는 효과가 있다.Therefore, the present invention can record and reproduce video signals of two broadcast channels simultaneously as one magnetic tape, which is very useful when there are two or more broadcast channels to be recorded at the same time.
