Benefits of technology
Enables real-time IPTV streaming on DLNA devices without the need for content download or complex gateway conversions, reducing costs and infrastructure dependencies, while maintaining seamless network integration.
Problems solved by technology
However, the former method requires download time for temporary storage of content on the home server, and hence it is difficult for the users to enjoy video whenever they like, which makes the method not suitable for live viewing and listening.
High-performance hardware is thus required, and also software becomes complex, which drives up the cost of the RG.
This presents an obstacle to offering IPTV services on the open Internet due to such reasons that the IPTV services available to the user are limited to those of the vendors provided by the access lines.
Although it is possible to provide a new gateway device in the home IP network separately from the residential gateway (RG), in this case, depending on the network topology, overlapping transmissions of content streaming data may occur in the home network, resulting in wasted bandwidth within the home network.

A configuration is provided in which a device within a home network receives and plays back content from a server that is located outside the home network. A home IMS gateway maps the external server located outside the home network as a virtual home network device, and executes reception of a content provision service provided by the external server through application of the mapping information. Further, at the time of executing switching processing of channels that provide content provided by the external server, the home IMS gateway executes termination of an inactive channel that occurs due to the channel switching.
Description
TECHNICAL FIELD[0001]The present invention relates to an information processing apparatus and an information processing method, and a computer program. More specifically, the present invention relates to an information processing apparatus and an information processing method, and a computer program which realize use of data supplied from outside a home network by devices within the home network.BACKGROUND ART[0002]With the proliferation of PCs and digital household electric appliances, interconnecting these devices via a home IP (Internet Protocol) network to share and enjoy digital content such as video, audio, and photographs is becoming a reality. For example, the DLNA (Digital Living Network Alliance) defines technical specifications and implementation guidelines necessary for sharing digital content by those digital appliances to allow connectivity between devices of different vendors. These specifications and guidelines have become the industry standards for home IP networks....
