Abstract

본 발명은 디지탈-브이씨알(D-VCR)에 관한 것으로, 특히 동기블럭의 순서에 따라 동기신호를 다르게 기록하고 이로부터 동기신호를 안전하게 검출할 수 있도록 한 동기신호 기록·검출방법 및 그 장치에 관한 것이다. 본 발명은 적어도 2개 이상의 서로 다른 동기신호를 이용하여 연관성이 있는 동기블럭의 순서에 따라 기록한고 이러한 동기신호들이 검출되는 시간을 체크하므로써 동기신호를 오검출할 확률을 줄일 수 있다. 따라서 후단의 S-P변환부에 안전한 데이타를 공급할 수 있는 효과를 가져온다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital-VCR (D-VCR), and more particularly, to a synchronization signal recording / detection method and apparatus for recording a synchronization signal differently according to the sequence of a synchronization block, and to safely detect the synchronization signal therefrom. It is about. According to the present invention, at least two different synchronization signals are recorded in the order of the associated synchronization blocks, and the probability of falsely detecting the synchronization signals can be reduced by checking the time when the synchronization signals are detected. As a result, it is possible to supply secure data to the S-P conversion unit at a later stage.
