  • Information processing apparatus, information communication system, information processing method, and computer program
    Patent number: 8230004
    Abstract: A configuration is provided in which a device in a home network receives content from a server outside the home network and plays the content. A home IMS gateway maps an external server outside the home network as a virtual home network device, and provides mapped server information in response to reception of a device discovery request from a content playing apparatus (DMP) in the home network. Furthermore, a content obtaining request is transferred from the content playing apparatus to the external server so that the external server sends content to the content playing apparatus. Authentication and key exchange defined in DLNA are executed between the content playing apparatus and the home IMS gateway, and a key generated is sent from the home IMS gateway to a content providing server. The external server sends encrypted content based on the received key.
