基于网络的视频监控系统 随着时代的发展，人们对安全防范也越来越重视，而数字化视频监控系统在音视频录像、报警录像联动、硬盘存储、多画面显示等方面都有突出表现，因此在安防领域逐渐占有了一席之地。本文提出的基于网络的视频监控系统实现了对数字硬盘录像机的控制功能，其远程客户端软件可以同时播放四路具有高达Dl分辨率的图像数据。 第一章论述了视频监控系统和数据压缩技术的发展动态。 第二章对客户端软件的开发环境及平台进行了选择，并就其中使用的关键技术:windows sockets编程技术、windows多线程技术、windows图像显示技术、MPEG-4编解码与数据传术技术、流媒体技术做了简介。 第三章详细论述了客户端软件的设计及实现。包括客户端软件的整体设计和各模块的设计实现，最后给出了实现结果。 第四章是论述了实时流媒体播放器的设计和实现，包括主要模块设计实现 (网络接收模块、解码模块、显示模块、操作控制模块)、其他模块设计实现(显卡能力探测模块、表面管理模块)、性能优化(缓冲、共享内存、线程模型)。 第五章对系统进行了总结，并为系统进一步发展提出了展望和规划。 (network-based video surveillance system with the development of the times, people are increasingly security attention, and Digital Video Surveillance System in video and audio video, police video linkage, hard disk storage, Multi-screen display, and other aspects outstanding performance in the field gradually Security occupies a place. This paper presents the network-based video surveillance system for the digital disk video recorder to the control function, its remote client software can be broadcast simultaneously Four Dl with high-resolution image data. The first chapter of the video monitoring system and data compression technology developments. Chapter II of the client software development environment and platform choices, and the use of the key technologies : Programming windows sock)
