Research Of Digital Home Networking Standards And Application System

Along with the popularization of consumer electronics and the maturation of wireless communication technology, the technology and the standard of family network, which plays an important role in digital home, is becoming the attention and research hot spot in domestic and overseas. The interface standard of family network connection involves all information equipment, including consumer electronics, computer, communication field. The standard is the basis of interconnection, intercommunication,3C fusion, and the scaled economy which can save the money to cut the price. At present, there exist many interconnection and intercommunication technical standards in the domain of digital home. Enterprises stand by different technical standards based on their respective benefit, therefore, the corresponding manufacturers develop their products for digital home compliance to different standards. It's difficult to implement the true interconnection and intercommunication between these products, which becomes a bottleneck of the industrial development of digital home. Consumers think that it's not the "digital home" if the products they bought from different company can't realize seamless interconnection and resource sharing. And these realizations depend on open standard. Therefore, standard is very important for establishing the digital home industrial chain and constructing the digital home industrial environment.This paper studied the domestic and overseas mainstream family network standard firstly:ITopHome, IGRS, UPnP and DLNA. We analyze their technical standard system and their core agreement group, and then compare and analyze these standards to propose the possibility of their fusion. Through comparation and analization of these standards we realize the importance of UPnP. Therefore, we have conducted the thorough research to the UPnP standard in the following work. We have designed and realized the family media service system based on the UPnP and have carried on the demonstration through the experiment to this system.According to the interconnection and intercommunication issues which were brought by the multiplicity of digital home standards, this paper proposes the digital home standard fusion scheme based on the home service bus. It will lays the foundation for the ubiquitous interconnection and intercommunication of the digital home.At last, the paper summarizes the problems that still exist, and then puts forward several proposals to the next step research work.
