This realization of above functionality needs UPnP protocol in middleware architecture. UPNP is a mainstream protocol in the home network, and it is based on the application layer protocol on top of TCP / IP.UPNP develops a series of norms for the access,found and control of digital devices.A variety of household appliances connect through a home network and work together.It allows user to use any device to access and enjoy multimedia content of the home network. This thesis is based on this goal, through in-depth analysis of the UPNP protocol stack structure and characteristics of the Android platform,implement a UPNP media player on the Android platform.Firstly,with combination of the overall framework for the UPNP media playback system,the thesis proposes the implementation of UPNP media player,and describes the implementation process of UPNP media player in detail.The thesis use the Cling library to achieve the UPNP protocol stack functionality,the Android multimedia interface to achieve the media player functionality,finally successfully transplants the application on the Android platform embedded development board. Generally speaking, the media server program developed by the project team runs on PC ,the embedded development board is regarded as a media player. The wireless router connects the PC and the Android embedded development board together. Embedded development board can successfully play the multimedia resources in the media servers, and the user can control the media player through the control point interface. This thesis successfully simulates the scene in the digital home network. Key words: Digital Home Network, UPNP Media Player ,Android System, Media
