视频服务器

• Based on lan . established a model of supervise system model in chapter six , all of the work in this thesis is summed up . the future research of digital video supervise system is prospected
  在第五章中，对基于局域网的视频监控系统建立了的网络模型，并对以视频服务器作为终端数据采集设备的视频监控系统进行功能模型设计。
• In the environment of clustered video server , the advantage of adopting hierarchical storage architecture is its ability to assign the appropriate storage hierarchy to each program based on its locality of access
  在集群式视频服务器中，利用vod系统的访问局部性，将节目存储在层次化的存储系统中，以节省系统的存储费用和提高命中率。
• Current research of vls - vod are focused on scalable software and hardware architecture and effective bandwidth - sharing mechanism , which are two foundation stones in scaling the vod system to serve more users
  可扩展的视频服务器软硬件体系结构和高效的带宽复用策略是扩展vod系统服务规模的两个主要手段，已成为超大规模vod研究中的热点。
• At last , based on theory research above , aimed at distribute video on demand application , the thesis realizes the mpeg - 4 video server ' s system structure , finish the software module design
  论文最后在以上理论研究基础上，针对分布式视频点播系统应用，提出了mpeg - 4视频服务器系统结构，完成了各模块的软件设计，实现了mpeg - 4视频服务器。
• At last , in chapter six we test our design system using video capture rate and compression ratio guidelines . then we proposed some methods that contribute much to the upgrading of the current system
  接着提出从利用qualitybox改进系统性能，利用directdraw加速系统显示，动目标检测扩展系统功能，构建嵌入式视频服务器四个方面的系统改进方向。
• All of this paper ' s work has turned out that cluster computing approach is feasible . as a result , the lcvs is proved as a good solution for vs in dedicated vss , which can meet the requirements for performance and stability
  根据本文工作的最后结果，证明lcvs实现的视频服务器可以满足视频服务系统的要求，并且能够提供设计时要求达到的性能和表现要求。
• In this paper , to construct a high stability digital broadcasting system , we design and implement a king of multi - channel broadcasting video server system , at last we advice an applying environment using our video server
  为了构建高可靠性的数字播出系统,本文提出并实现了一种多通道播出视频服务器系统,并推荐了针对该视频服务器系统的一个应用环境。
• At the same time in order to balance the load of i / o , distributed file storage technology is put forward ; it can distribute the i / o load to every video server . this method is proved by the experiment of simulation
  在该部分为了均衡i o负载，我们提出了一种文件分布存储技术，它可以将1 o负载均匀地分配到各个视频服务器中，并存仿真实验中得到了有效验证。
• Based on the analysis of the vls - vod requirements and two existing architectures , multi - node video server and virtual server , we present a scalable video server architecture , named as vvs , for virtual video server
  本文分析了超大规模vod应用对可扩展视频服务器的需求，在现有多节点服务器和虚拟服务器结构的基础上，提出了可扩展的虚拟视频服务器体系结构vvs 。
• In addition , at present , most vod systems are based on wan ( wide area network ) , so their designs are very complicated and the proprietary video servers are expensive and not fitf ul for lan ( local area network )
  再次，现在的大多数vod系统都是基于广域网的解决方案，其设计不但复杂，而且其专用的视频服务器价格十分昂贵，几十万甚至上百万的价格很难适用于小型应用领域。
