【摘要】 随着消费电子产品的普及以及无线通讯技术的成熟,家庭网络作为数字家庭的重要组成部分,其相应的技术和标准已经成为国内外关注和研究的热点。家庭网络连接的接口标准涉及到所有的信息设备,无论消费电子、计算机,还是通信领域都会受到接口标准的影响。有标准才能互连互通,完成3C融合,才能创造规模经济,有了规模经济,才能降低价格。目前在数字家庭领域存在着多个互联互通技术标准,不同的企业基于各自的利益导向支持不同的技术标准,不同厂商开发的数字家庭产品也就遵从不同的标准,这些产品之间难以实现真正的互联互通,成为数字家庭产业发展的一个瓶颈。而从消费者的角度来说,如果从不同设备商处购买的设备之间不能实现无缝互联、资源共享,那么“数字家庭”的概念无疑也会大打折扣。而这些的实现都依赖于开放的标准,因此标准对于确立数字家庭产业链,建设数字家庭产业环境至关重要。本文首先研究了国内外主流家庭网络标准：e家佳、闪联(IGRS)、DLNA和UPnP,深入分析了它们的技术标准体系及其核心协议组,并对这些标准进行了比较分析提出了它们之间进行融合的可能性。通过对这些标准的比较分析我们了解UPnP协议的重要性,因此在接下来的工作中我们对UPnP标准进行了深入的研究,设计并实现了基于UPnP协议的家庭媒体服务系统,通过实验对该系统进行了演示。针对目前数字家庭多标准协议所带来的互联互通互操作问题,本文主要基于家庭服务总线的架构,提出基于家庭服务总线的数字家庭多标准协议融合方案,进而为数字家庭无处不在无所不在的互联互通互操作奠定基础。最后,本文对课题所做的工作进行了总结,并对下一步研究工作提出了几点建议。更多还原

【Abstract】 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.更多还原
