Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

VCR에 있어서, 전원 “온”상태에서 키입력, 모드변경, 신호입출력 등 아무런 신호가 검출되지 않을시 자동으로 전원을 차단하는 장치 및 방법에 관한 것이다.In the VCR, the present invention relates to an apparatus and a method for automatically shutting off a power when no signal is detected, such as a key input, a mode change, a signal input / output, etc. in a power “on” state.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

통래 VCR의 경우 전원을 “온”시킨 후 키입력, 모드변경, 신호입출력 등 아무런 신호가 없을시에도 계속해서 전원 “온”상태를 유지하였으므로 상당한 소비전력을 낭비했던 문제점을 해결한다.Conventional VCR solves the problem of wasting considerable power consumption since power is “on” and power is kept “on” even when there is no signal such as key input, mode change, signal input / output etc.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

전원 “온”상태에서 키입력, 모드변경, 신호입출력 등 아무런 신호가 검출되지 않을시 자동으로 전원을 차단하여 VCR이 자동절전 기능을 수행하도록 하는 방법을 제공한다.Provides a way for the VCR to perform the auto power off function by automatically shutting down the power when no signal is detected, such as key input, mode change, signal input / output, etc.

4. 발명의 중요한 용도4. Important uses of the invention

Claims

A video power saving device, comprising: power supply means for supplying power to each video device, key input means for generating various V-Cal control key signals, and various control key signals received from the key input means for control; A control means for generating a signal and generating a control signal to perform a power saving function, a video deck means controlled by the control signal of the control means to reproduce a video, and a signal reproduced and output from the video deck means. A chromaticity / luminance signal processing means for receiving chromaticity and luminance signal processing, and a signal for detecting the presence or absence of an external signal input through the chromaticity / luminance signal processing means and controlled by the control signal of the control means. A detection means and a switching means controlled by a control signal of said control means to interrupt the supply of power. Power saving apparatus of the video, characterized by.

In the video power saving method, a key input, a mode change, and an input / output of a signal are detected in a detection process, a driving process for driving a timer when not detected in the detection process, and a timer for a predetermined time in the driving process. When the key input, mode change, and signal input and output are all detected, the power is cut off.
