Abstract:
An apparatus, system method and computer program product configured to transmit data over a broadcast network. The data is encrypted and decoded using a decryption key available to terminals in combination with a digital rights object. A media guide is broadcast to the terminals. Information from the media guide is also stored by a request handling means in order to ensure that information, such as pricing information, broadcast to the terminals is synchronized with information used to register a terminal as a subscriber. A request is sent from a terminal to the broadcast network through a second network. Authentication information identifying the terminal may be included in the request without manual input from a user of the terminal. Authentication information is extracted from a component or added to the message by a component of the second network. The digital rights object is then sent to the terminal via the second network.
