【摘要】 个人终端设备(包括智能手机、平板电脑、笔记本等)的多样化,使用户对服务移动性的要求越来越高。目前的研究多数集中在服务器层面的被动迁移,而面向客户端的主动迁移正在成为研究热点。作为互联网的典型应用,流媒体服务在发展过程中急需解决如何实现主动迁移的问题。文中在分析了RTSP协议和其他迁移系统的基础上,分别构建了流媒体服务模块和连接管理模块,并以服务状态信息作为迁移内容,实现了用户在不同终端上的流媒体迁移。更多还原

【Abstract】 With the variety of personal terminal devices,including smartphone,pad,notebook etc,service mobility is increasingly needed for users.Nowadays the migration is focused on service for servers,and the migration for applications of personal terminal is becoming hot topic.Streaming media service is the typical application of internet,and it has a great desire of migration.It is based on the analysis of real time streaming protocol and some parts of other migration systems,making the system consists of two modules are streaming media service model and joint management model,and using the status parameters of streaming media as migration contents to achieve the streaming media migration for one user in different terminals.更多还原
