摘　　要：详细讨论了UPnP协议的体系结构、设备间互操作机制、网络组成以及DTCP-IP协议并在此基础上实现了基于UPnP AV架构的数字媒体适配器系统。本系统中用户可以使用遥控器借助DMA浏览、搜索、播放DMS上的媒体文件。DMA和DMS的通信使用DTCP-IP协议保证其通信安全性。This paper discusses the UPnP protocol architecture, interoperability mechanism between equipments, network configuration and DTCP- IP protocol. And a digital media adapter system based on the structure of the UPnP AV is presented in this paper. Users in the system can use the remote controller to browse, search and play media files in the DMS through DMA. Communication between DMA and DMS adopts DTCP-IP protocol to ensure their communications security.
