发明名称 Apparatus, system, method and computer program product for distributing service information and digital rights for broadcast data
摘要 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.
