20110131389 | METHOD FOR UPDATING DATA IN MEMORIES USING A MEMORY MANAGEMENT UNIT - A method for updating, in the background, data stored in physical memories without affecting the current operations performed by the microprocessor. When the update is completely terminated, the application switches from an old version to a new version. This switching occurs by a reconfiguration of the page table during which a first sub-tree structure of pointers accessing the old version of data stored in memories is replaced by a second sub-tree structure of pointers thus allowing access to the new version of data. This update method prevents incoherent transitory states of the system as the latter works with the previous data version until the installation of the new version becomes usable. In the case of an interruption to the update process, the application can always reinitialize the update since the old version of data can be reactivated by returning to the previous configuration of the page table. | 06-02-2011 |

20130279694 | SYSTEM AND METHOD TO RECORD ENCRYPTED CONTENT WITH ACCESS CONDITIONS - A television event may be consumed after been stored in a mass memory of a multimedia unit, but still fully relies on the security of a secure device. A conversion of a received content aims at firstly descrambling the content using control words included in entitlement control messages and immediately re-encrypting the descrambled content by a unique key generated specifically for this content. Access conditions attached to the entitlement control message containing the control word are temporarily stored and once the decryption is terminated, the secure device produces an information block. This information block containing for example access conditions and an identifier of the content is either stored into a secure memory of the secure device or stored in the mass memory with the encrypted content. The unique key is made up of a combination of a root key specific to the secure device and the information block. | 10-24-2013 |
