Abstract

본 발명은 디지탈 VCR(Video Cassete Recorder) 동작방법에 관한 것으로, 특히 디지탈화된 VCR 테이프로부터 영상 및 음성신호를 읽어들여, 디지탈에서 아날로그로 변환시켜 입력되어진 신호를 영상 빛음성으로 출력시킬 수 있도록 한 디지탈 VCR의 동작방법에 관한 것이다. 이러한 본 발명은 메모리로 구성된 VCR테이프로 부터 디지탈 영상 및 음성신호 데이터를 읽어 들인후 이 데이터 값을 아날로그 신호로 변환시키므로 장시간 사용에서 발생되는 데이타의 오류를 방지 할 수 있는 이 점과 VTR화면에서 정지 및 고속화면으로 동작시킬때 발생하는 노이드 현상을 제거할 수 있게 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of operating a digital video cassette recorder (VCR). In particular, a digital VCR tape reads video and audio signals, and converts them from digital to analog so that the inputted signals can be output to video light audio. A method of operating a VCR. The present invention reads digital video and audio signal data from a VCR tape configured as a memory and converts the data value into an analog signal, thereby preventing errors in data generated during long time use and stopping at the VTR screen. And it is to be able to eliminate the phenomenon of the phenomenon that occurs when operating the high-speed screen.
