Proposal on Wide Area DLNA Communication System

The spread of DLNA (digital living network alliance) certified consumer electronics has already started and there are some proposals for communication systems involving two home networks linked via virtual private network (VPN), that aim to use consumer electronics from the Internet. However, those systems have some problems. For example, against the user´s wishes, the ITN connection makes all the contents available for other users as well. The user cannot access content because DLNA devices refuse access from outside the home network. In this paper, we propose a new system that expands the interconnection area from a home network to a mobile phone and consumer electronics in other home networks. Furthermore, we evaluate the proposed system by constructing a test bed that includes consumer electronics obtainable at stores.
