Abstract

본 발명은 입력된 데이터에 따라 주변장치의 작동을 전반적으로 제어하는 마이컴과, 마이컴에서 출력되는 데이터에 따라 방송신호를 튜닝하는 제1, 제2튜너, 상기 제1,2튜너에서 출력되는 복합영상신호를 중간주파신호로 처리하는 데1,2중간주파 처리부, 상기 제1,2중간주파 처리부에서 출력되는 신호를 마이컴에서 출력되는 데이터에 따라 주화면 신호와 PIP신호를 출력하는 신호처리부, 상기 신호처리부에서 출력되는 신호를 포함하여 수상관에 공급하는 혼합부, VCR에서 출력되는 비데오 신호에 동기신호가 있는가를 검출하는 동기 검출부 및 , 상기 동기 검출부에서 출력되는 신호를 완충하여 마이컴에 공급하는 완충부로 구성되어져 VCR의 데크부에 안착된 기록매체에 기록된 데이터를 텔레비젼 전화면에 디스플레이 할때 비데오 신호가 무신호이면 텔레비젼 대화면에는 TV방송신호를 재생하고 소화면으로 비데오 신호를 재생하다가 비데오 신호가 검출되면 자동으로 비데오 신호를 텔레비젼 전화면에 디스플레이 하므로 비데오 신호 재생시 수신호일때 시청자에게 불쾌감을 주지 않게 되며, 비데오신호 무신호인 기간동안 마다 TV방송을 시청할 수 있는 복합영상기록 재생기의 재생모드 전환장치 및 그 방법에 관한 것이다.The present invention provides a microcomputer for controlling overall operations of a peripheral device according to input data, and a composite image output from the first and second tuners and the first and second tuners for tuning a broadcast signal according to data output from the microcomputer. 1, 2 intermediate frequency processing unit, a signal processing unit for outputting the main picture signal and the PIP signal according to the data output from the microcomputer to the signal output from the first and second intermediate frequency processing unit, the signal Mixing unit including the signal output from the processing unit to supply to the water pipe, a synchronization detection unit for detecting whether there is a synchronization signal in the video signal output from the VCR, and a buffer unit for buffering the signal output from the synchronization detection unit to supply to the microcomputer If the video signal is no signal when displaying data recorded on a recording medium seated on the deck of the VCR on the full screen of the VCR, the On the big screen of the video, the TV signal is played back and the video signal is displayed on the small screen. When the video signal is detected, the video signal is automatically displayed on the full screen of the TV. The present invention relates to a playback mode switching device and method for a composite video recording / reproducing apparatus capable of watching TV broadcasts during a signal-free period.
