Abstract

A media server is hosted in a service provider'"'"'s network so that media content can be stored from or rendered to a private network such as a Digital Living Network Alliance (DLNA) network. Media content may be stored directly by accessing the media server or by downloading the media content to the media server. The media server may support discovery of media content in a local DLNA network, media content fulfillment from a service provider network, and content delivery for a device on the DLNA network. The media server may further route regional traffic to the DLNA network from a media source such as a video on demand (VOD) server or an Internet media server.
