Abstract

비디오 카세트 레코더의 전원인가시 및 모드 전환시에 화면을 안전화시키기 위한 방법이 기술되는바, 이는 전원인가시 및 모드변환시에 수직동기신호를 검출하여 이를 소정시간동안 지연시켜 수직동기 신호에 위상을 맞추어 절환되는 입력신호를 선택하여 화면을 안정화시키게 된다.A method for securing a screen when a video cassette recorder is powered on and a mode switch is described, which detects a vertical synchronous signal during power-up and mode switching, delays it for a predetermined time, and adjusts the phase to the vertical synchronous signal. The screen is stabilized by selecting a switching input signal.

Claims (1)

입력절환 스위치를 마이컴이 제어하여 기능키이로 선택된 입력신호를 출력하는 비디오 카세트 레코더의 화면 안정화 방법에 있어서, 전원 인가시 수직동기 신호를 검출하고, 상기의 수직동기 신호가 검출될 경우에는 이를 소정시간 동안 지연시킨뒤 입력신호를 선택하고, 모드 변환시에도 수직동기 신호를 검출하여 이를 소정시간 동안 지연시킨뒤 상기의 수직동기 신호에 위상을 맞추어 절환되는 입력신호를 선택하는 단계를 포함함을 특징으로 하는 화면 안정화 방법.A method of stabilizing a video cassette recorder in which a microcomputer controls an input switching switch and outputs an input signal selected by a function key, wherein the vertical sync signal is detected when power is applied, and a predetermined time is detected when the vertical sync signal is detected. And selecting an input signal after delaying the signal, and detecting the vertical synchronization signal during the mode conversion, delaying the input signal for a predetermined time, and selecting an input signal switched according to the phase of the vertical synchronization signal. How to stabilize your screen. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
