摘要
为解决数字家庭中设备间媒体共享的问题,研究UPnP协议和UPnP AV架构,设计实现基于嵌入式智能终端的媒体共享系统。针对智能手机、平板电脑的便携特性,单独实现控制点功能,支持"推播"模式,支持智能移动设备单独做控制点的操作逻辑。核心功能模块采用native开发,上层采用Java进行界面控制,已在Android设备上成功部署。测试结果表明,该系统可以很好地实现局域网内的媒体资源共享,提升用户娱乐体验。
To deal with the problems of media sharing among devices in the digital home ,the UPnP protocol and the UPnP AV architecture were studied .A media sharing system based on the embedded intelligent terminal was designed and realized .Aiming at the portability of smart phones and tablet computers ,the function of the ControlPoint was achieved separately in this system . In addition ,the“Push”model and the operation logic where the smart mobile device is used as the ControlPoint separately were also supported by this system .The key module of this system was developed using the native-code ,and the surface layer was de-veloped using Java which controlled the user interface .The system runs well on Android devices .Experimental results show that the system can achieve media resource sharing within the LAN and enhance the user entertainment experience .
