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。
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。
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;
Digital Video Recorder is a system that includes hard disk video, intelligent replaying and searching and other functions digital surveillant video system. 数字硬盘录像机(DVR)是集硬盘录像、智能回放检索等多种功能于一体的智能数字监控录像系统。
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。
The aim of our project is to meet the need of video monitoring hard disk recorder, in which a video codec system based on MPEG-4 is applied. 本课题的研究目的是针对视频监控硬盘录像机应用的需要,研制并开发出一套基于MPEG-4标准的实时视频编码系统。
In this paper, the direct video stream pump, the file layout policy in the disk subsystem, and the scalability of the proposed system are discussed in details. 本文将详细讨论直流视频流泵、磁盘子系统的文件释放策略以及系统的可伸缩性。
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。
Aimed at the complexity of network-structure of the conventional simulation-supervision and the video recorder of multi-media hard disk, a kind of the network video supervision system based on MPEG-4 is proposed. 针对传统的模拟监控系统及多媒体硬盘录像机组网复杂问题,提出并实现了一种基于MPEG-4算法的网络数字视频监控系统。
