DLNA 数字家庭媒体播放系统的设计与实现

摘要

本文提出了一种数字家庭 DLNA 媒体播放系统总体方案，通过基于 DLNA 架构 UPnP 协议设计了跨平台操作的控制终端 DMC 软件系统，设计并实现了其中的 socket 通信、设备管理、播放控制和用户界面等模块，将智能移动终端映射为符合 DLNA 规范的 DMC 设备。测试结果表明，研制的播放系统性能稳定，DMC 软件系统界面友好，可扩展性强。%This paper propose a digital living DLNA media player system. On the basis of UPnP protocol,a set of cross-platform DMC device software system is designed to turn the smart mobile terminal into digital home DMC de-vice,including the design and implementation of socket communication,device management,play control and user interface modules. The test results show stable performance of the media player system with user-friendly interface and good scalability of the DMC software system.
