The prevalence of information appliances supporting DLNA (Digital Living Network Alliance) such as televisions, recorders, and mobile phones has made it possible to share digital contents (e.g. videos, music and pictures) among appliances connected to a local network. However, DLNA does not let the people share contents over different networks via the Internet. In this paper, the authors propose a network architecture where they adopt their SOAP method to mobile devices and use them as mobile gateways to consume digital contents from remote networks. They also confirm its practicality with a prototype.
