Abstract
본 발명은 자동파워온 및 채널선국기능이 구비된 TV시스템에 관한 것으로, VCR데크로부터 외부입력단자를 통해 입력되는 수직동기신호를 검출하는 수직동기신호검출부와, 이 수직동기신호검출부를 통해 입력된 수직동기신호의 검출유무를 비교판단하고 그 판단결과에 따라 자동으로 TV시스템의 파워온기능 및 채널선국기능을 실행시키는 마이컴과, 이 마이컴의 뮤트제어신호에 따라 영상신호를 뮤트시키는 뮤트스위칭부와, 이 마이컴의 파워온제어신호에 따라 TV시스템에 구동전압을 공급하는 전원공급부를 구비하여, VCR 재생시 입력되는 수직동기신호를 검출하여 비교판단하고 그 판단결과에 따라 TV의 파워온기능 및 비디오채널선국을 자동으로 실행시키도록 하므로써, 비디오재생에 별도의 조작이 필요없게 되므로 이에따라 사용의 편리성을 향상시키게 됨은 물론 시스템의 일부기능이 자동으로 실행되므로 이에따라 시스템의 기능성도 증가하도록 된다.The present invention relates to a TV system having an automatic power-on and channel tuning function. The present invention relates to a vertical synchronous signal detection unit for detecting a vertical synchronous signal input from an external input terminal from a VCR deck, and a vertical synchronous signal detection unit. A microcomputer which compares and detects whether a vertical synchronization signal is detected and automatically executes the power-on function and channel tuning function of the TV system, and a mute switching unit that mutes the video signal according to the mute control signal of the microcomputer. And a power supply unit for supplying a driving voltage to the TV system according to the power-on control signal of the microcomputer, detecting and comparing the vertical synchronization signal input during the VCR playback, and determining the power-on function and video of the TV according to the determination result. By automatically executing channel tuning, there is no need for a separate operation for video playback, thereby improving the convenience of use. Since kige doemeun well as some functions of the system to run automatically is to increase the functionality of the system yiettara.
