20120185894, "Method and system for order relationship authentication, and mobile multimedia broadcasting-conditional access system," assigned to ZTE Corporation (CN).
A method for order relationship authentication, including: a visited mobile multimedia broadcasting-conditional access system (MMB-CAS) acquiring operation and management information from a corresponding business operating support system (BOSS); the visited MMB-CAS receiving a request message for accessing service key from a user and triggering order relationship authentication; the visited MMB-CAS requesting the home MMB-CAS to perform order relationship authentication on the user; and the visited MMB-CAS receiving an order relationship authentication result of the user fed back from the home MMB-CAS, and performing corresponding processing. The present invention also provides an order relationship authentication system and a Mobile Multimedia Broadcasting-Conditional Access System. By the present invention, the amount of data synchronized between MMB-CASs is reduced and the overall performance and reliability of the system is improved.
20120159146, "System and Method for Transcoding Content," assigned to General Instrument.
A system is provided for use with secure content in a first format. The system includes a conditional access device, a transcoding device and a media processor. The conditional access device is arranged to receive the secure content and can generate second secure content based on the secure content. The conditional access device is can further provide the second secure content to the transcoding device. The transcoding device can transcode the second secure content into transcoded content of a second format, can secure the transcoded content as secure transcoded content and can provide the secure transcoded content to the media processor.
