摘要
数字硬盘录像系统在各个应用领域发挥着重要的作用,录像功能模块是其核心部分。针对以往DVR录像功能模块在录像时间的精确度等方面存在的一些不足,提出了一种新的录像功能模块的设计方案,经实际应用证明,能够较好地满足精确时间录像,各通道录像时间同步,文件精确分割、预录等功能要求,适应了各种不同业务的应用需求。
Abslracl：Digital hard disk video recorder system has been playing an important role in various application regions. Record function module is its core. To solve some problems of DVR＇s record module such as precise time record,a new design scheme about record function module is presented. This scheme, proved by practice, could meet the requirements of precise time re- cord,multi channel record synchronization, file precise division and prerecord. It can be widely used in various applications.
