Application And Study Of Home Gateway Middleware

ameworkAlong with the development of economy and technology, people don't need the simple voice transfers and unilateralism video from communications service, they need more faster, more enrichment and alternation media service of telecom broad band. Besides electrons reformation to digital, it is also every important to constitute a family network for broad band access, contact internal, share the content.After some years'market cultivation, home network market is growing better.As the important part of home network,home gateway is the control center of home network system.The play of video and audio media stream,network games,communication with outside can all be controlled by the gateway. It introduces the Dual Protocol Stack bas ed on IGRS and UPnP, causes its'function intelligence and consummation.This compares the corresponding layers of IGRS protocol and UPnP protocol,analyses their features in addressing,discovery,descripion,control and so on,abstracts the same fu ndamental modules of them,tackles the problems brought by the differences in all the lay ers, and present a project to realize the IGRS and UPnP Dual Protocol Stack in Digital H ome Network. Meanwhile, in order to implement the AV application of Digital Home Ner work, the paper presents an effective project to realize the Dual Protocol Stack AV Applicat ion Framework. This fr presents the way to realize the Dual Protocol Stack Control Point, Dual Protocol Stack Media Server and Dual Protocol Stack Renderer, and gives the detai led module design and implementation process.
