HOME GATEWAY AND CONTROL POINT FOR SUPPORTING A SHARE OF MULTIMEDIA CONTENTS IN MEDIA SERVER IN PRIVATE NETWORK WITH MEDIA MEDIA RENDERER IN REMOTE PRIVATE NETWORK

摘要

PURPOSE: A home gate and control point are provided to share content between a first home network and a second home network by changing application level gateway port numbers. CONSTITUTION: A changing unit(836) receives a content URI(Uniform Resource Indicator) which displays the location of content within a media server. The transformation unit changes ALG(Application Level Gateway) port numbers which are previously established for the IP address of a home gate way and the media server. A transmission unit(837) transmits the content URI changed by the transformation unit to a media rendering unit. The media rendering unit is connected to the media server by using the content URI. The media rendering unit reproduces the content by downloading the content.
