Media service delivery system providing conditional access to media content from various client devices

摘要

A system for protecting the digital rights of content owners allows digital media to be delivered to only those media rendering client devices that have been approved for the media content. Before delivering requested media, the media service provider may determines whether the media rendering client device that requested the media is the type of device that is authorized to receive the request media. If it is, the media service provider may transmit the media to a middleman server over a network (such as the Internet). A middleman server may then serves the media to the client device over a local network. By allowing the media content to be distributed to approved devices only, the media service provider can prevent a user from using the media in a way that is not authorized by the content owner.
