Abstract
본 발명은 디지탈 데이타의 동기 신호 제어에 관한 것으로, 일반적으로 사용되고 있는 디지탈 데이타 재생 회로는 유효 데이타와 더미 데이타의 동기 블록을 판별하기 위해 서로 상이한 형태의 동기 블록을 형성함으로 기록 포맷을 맞추기 위한 회로가 복잡해지고, 재생시에도 유효 데이타 블록과 더미 데이타 블록을 판별하기 위한 회로가 부가되므로 복잡한 회로가 필요하게 되는 문제점이 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the control of synchronization signals of digital data. In general, digital data reproducing circuits have circuits for matching recording formats by forming different types of synchronization blocks to discriminate sync blocks of valid data and dummy data. There is a problem that a complicated circuit is required since the circuit for discriminating the effective data block and the dummy data block is added even during reproduction.
이에 따라 본 발명의 목적은 상기와 같은 종래의 디지탈 데이타의 동기신호 제어회로에 따르는 결함을 해결하기 위하여, 재생시 검출되는 동기 신호중 동기신호를 계수하여 더미 데이타 동기 블록의 동기신호를 억제하고 유효 데이타 동기 블록만을 추출하는 동기신호 검출회로를 제공하는데 있다.Accordingly, an object of the present invention is to counteract the synchronization signal of the dummy data synchronization block by counting the synchronization signal among the synchronization signals detected at the time of reproduction in order to solve the defect caused by the conventional synchronization signal control circuit of digital data. A synchronization signal detection circuit for extracting only a synchronization block is provided.
