Title:
コンテンツ配信システム、及びゲートウェイ装置、並びにプログラム
Document Type and Number:
Japanese Patent JP5517733
Kind Code:
B2
Abstract:
A renderer (DMR) in a second local area network via an Internet is enabled to reproduce content in a first local area network. A content transmission system generates a virtual DMR corresponding to a DMR (content reproduction device) in a content reception system. A DMC (controller) and a DMS (content server) communicate with the virtual DMR. This enables content to be reproduced in an actual DMR in a different home network residing beyond the Internet without any modification on the DLNA standard. More specifically, the DMC and the DMS recognize the virtual DMR as if to be an actual DMR, communicate therewith. A transmission gateway device (transmission mechanism) relays communication destined for the virtual DMR (instructions and content) to a reception gateway device (reception mechanism). Also in the content reception system, the actual DMR is capable of processing communication from a different home network by communication only with the reception mechanism. This negates the need for modification on the DLNA standard.
