The software system has such characteristics as follow : all the information including streaming media are transported in transport - layer . its speed is much higher than in application - layer because it cuts down the time in data processing between two layers and can transport more pure data in equal time 本系统具有以下特点：所有信息数据的传送都在传输层实现，与在应用层实现相比，不仅减少了协议层之间流动的时间开销，而且提高了有效数据的传输速率，有利于实时播放多媒体影音文件。
Originally in the article , chapter one has stated the background of this subject and basic situation of this system ; chapter two introduced the key technology in real time system - streaming media technology and system used windows media service product technological tool , it offer the strong technological guarantee to develop the whole system ; in chapter three , analyze the realization mechanism of the system 在本文中，第一章说明了该课题的背景和本系统的基本情况；第二章介绍了实时播放系统的关键技术?流媒体技术和系统所使用的windowsmediaservice产品技术工具，为基于流开发适合于网络环境的多媒体远程实时系统提供了有力的技术保障；在第三章中，阐述了远程多媒体实时播放系统的实现机制。
Synthesizing the technology of network communication , multimedia and auto control , the server provide many function , such as data capturing , real time displaying , storage alarming , device controlling and network communication etc , which supports sixteen monitoring channels at the most 本系统综合利用网络通信技术、多媒体技术以及自动控制技术,服务器主机集数据采集、实时播放、存储报警、设备控制和网络通信等多种功能于一身,最多可以支持16路视频的实时监控。
Firstly , the dissertation introduced the content of the h . 264 / avc ’ s “ network friendliness ” technology , and then implements a streaming stack to follow the standard . the stack has the ability to add new module to apply the latest standard for transmission new type media data . the implement of h . 264 standard consists of the parameter set concept , nal and packaging 本文针对项目中使用的基于x86架构的纯软件解码的ip机顶盒平台,从h . 264网络媒体实时播放的角度,对支持h . 264的流媒体协议栈和h . 264解码器优化这两个方面进行了研究、应用。
