METHOD AND APPARATUS FOR ENABLING CONTENT PROTECTION OVER BROADCAST CHANNELS

摘要

A receiver for receiving a media license includes a communication unit configured to receive, from a server, a first message comprising broadcast media data comprising at least a portion that is protected and receive, from the server, a second message comprising encrypted license data and a controller configured to generate a request for a third message indicating the encrypted license data from a content decryption module (CDM) of the receiver, identify one or more hash codes in the second message, and identify the encrypted license data for the receiver based on a mapping between the one or more hash codes and a hash of the third message.
