Abstract:
A communication infrastructure containing a plurality of templates stored in an intermediate routing node and data rights management service function that determines an incoming packet contains media content by comparing the packet contents with the plurality of predefined templates and verifies whether associated license in the packet is valid. The intermediate routing node triggers the data rights management service function, if the associated license is not valid. The data rights management service function verifies rights of the user of the destination device to use the media content and interacts with the destination device to verify the validity of the license. In addition, the intermediate routing node interacts with a media manufacturer's server to verify the validity of the license. An external data rights management server may in part or full carry out the DRM functionality, to assist the intermediate routing node.
