Claims (3)

독립된 방송신호를 튜닝하고 검파하는 두개의 튜너 및 중간주파수 처리부와, 상기 튜너 및 중간주파수 처리부에서 출력된 두개의 영상신호의 수직, 수평동기신호를 검출하여 수직동기간의 시간차에 따라 일영상신호를 선택하여 딜레이시키고, 또다른 영상신호와 수직동기와 일치하는 일영상신호를 출력하고 수평동기신호를 일치시키는 제어부와, 제어부의 제어에 의해 수직동기가 일치하는 일영상신호와 또다른 영상신호를 소정의 수평구간마다 걸러서 합성하는 믹서부와, 상기 믹서부에서 합성된 합성신호중 사용자의 선택과 제어부의 제어에 의해 일영상신호를 분리하고 보충하여 완전한 일영상신호를 분리하고 보충하여 완전한 일영상신호를 복원하는 합성신호 분리부로 구성됨을 특징으로 하는 복수방송신호의 동시녹화 및 선택재생장치.Two tuners and intermediate frequency processing unit for tuning and detecting independent broadcast signals, and vertical and horizontal synchronization signals of two image signals output from the tuner and intermediate frequency processing unit are detected, and one video signal is selected according to the time difference between vertical periods. A control unit for outputting one video signal coinciding with another video signal and vertical synchronization and matching the horizontal synchronization signal, and controlling one video signal and another video signal having vertical synchronization according to the control of the control unit. A mixer unit for filtering each horizontal section, and one video signal is separated and supplemented by the user's selection and control of the synthesized signal synthesized by the mixer unit, and the complete one video signal is separated and supplemented to restore a complete one video signal. A simultaneous recording and selective playback apparatus for multiple broadcast signals, characterized in that consisting of a composite signal separation unit. 제1항에 있어서, 제어부가 일영상신호를 선택하여 딜레이 시킬때 아날로그 선택스위치와 최소 1필드를 메모리할수 있는 DRAM과, A/D 변환기, D/A 변환기로 구성된 메모리부를 이용함을 특징으로 하는 복수 방송신호의 동시녹화 및 선택재생장치.The method of claim 1, wherein the control unit uses an analog selection switch, a DRAM capable of storing at least one field, and a memory unit including an A / D converter and a D / A converter when selecting and delaying one video signal. Simultaneous recording and selective playback of broadcast signals. 제1항에 있어서, 제어부가 수평동기신호를 일치시킬때 수평동기신호를 비교하여 소정의 구간 딜레이시킴을 특징으로 하는 복수 방송신호의 동시녹화 및 선택재생장치.The apparatus of claim 1, wherein the control unit compares the horizontal synchronization signals and delays the predetermined intervals when the horizontal synchronization signals match. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
