With the rapid development of storage technology the video server as the core of hard disk broadcast system has been widely used .

随着计算机存储技术的快速发展，以 视频服务器为核心的 硬盘播出 系统得到了广泛的应用。

The system need not the third software which used to decode video and store each frame in the hard disk however the DirectShow is introduced to deal with MPEG-1 video bit streams . So the system is universal .

该系统不需要第三方 视频软件 支持，也不需要将每帧 视频 图像先解码存于 硬盘上，而是直接利用DirectShow来对MPEG-1视频流进行处理，提高了 系统的通用性；

There are several modules both used in video recorder and video player such as : hard disk driver module file system module and OSD module .

硬盘节目录制与 硬盘 节目回放功能中存在功能相同的模块，例如： 硬盘驱动模块、文件 系统模块、OSD菜单显示模块等。

The system not only has necessary Ethernet interface audio and video output keyboard mouse connection interface but also has hard disk IDE CF card and infrared interfaces which improves the system expansion ability .

系统中除了设计必备的以太网络，音 视频输出，键盘鼠标接口等，还提供了 硬盘IDE，CF卡和红外等接口，提高了 系统的扩展能力。

This paper analyzes the admission controls of large-scale video storage server and the admission tactics of video server based on disk system .

分析了大规模视频存储服务器的准入控制和基于 磁盘 系统 的 视频服务器的准入控制策略。

Digital Video Recorder is a system that includes hard disk video intelligent replaying and searching and other functions digital surveillant video system .
