Abstract: A method in which a network head-end associates with each segment of a list of at least one segment of a first segment block, a time datum that makes it possible to determine whether a deadline for sending an access rights request to an access rights server has changed; the network head-end sends to the terminal, together with each segment in the list, the associated time datum thereof; the terminal receives, together with each segment in the list, the associated time datum thereof, then changes a renewal deadline predetermined according to the last time datum received to obtain a new predetermined renewal deadline that enables the terminal to decide, according to the value thereof and at a given time before or equal to the changed deadline, to send an access rights request to the access rights server.

Abstract: The invention concerns a method for setting the level of definition of at least one image of a multimedia programme displayed on a screen of a terminal provided with at least one unit for characterising the multimedia programme and at least one unit for selecting predefined settings. This method comprises the following steps: the characterisation unit automatically acquires metadata attached to said multimedia programme and submits said data to the unit for selecting predefined settings, the unit for selecting predefined settings automatically selects the settings according to pre-recorded rules defined depending on the values of said metadata.

Abstract: A method for detecting an error in reading a data, includes in a step a) storing a first copy of the data item in a first area of an electronic memory and storing of a second copy of the data item in a second area. Step b) includes reading values of the first and second copies of the data item and in step c) there is a comparison of the read values of the first and second copies of the data item. In step d) if the read values of the first and second copies are identical, then no error is detected. In step e) if the read values of the first and second copies are different, then the method includes repeating steps b) and c). In step f), if the values read in step e) are identical, then an error in the reading of the data item is detected and, otherwise, no error is detected.

Abstract: The method for water-marking digital books with parameters includes developing, for each parameter, a new typeface on the basis of a pre-existing typeface, by creating at least one new code/glyph pair. The method includes developing a new coded text on the basis of the pre-existing coded text by replacing, in the pre-existing coded text, at least one code or group of codes from the pre-existing typeface. The method further includes allowing display of a character or a combination of characters from the digital book by the code or the group of codes from the new typeface allowing display of the graphically identical character or combination of characters on any screen. The code/group of codes from the new typeface has/have at least the code from the new code/glyph pair. The method also includes providing the new coded text and the new typeface as a water-marked digital book.

Abstract: A multimedia content processing device for processing multimedia contents implementing a plurality of virtual machines is provided. The device is able to receive encrypted multimedia content, protected by a content protection system, and provide the multimedia content in decrypted form to a user device, including an access controller authorizing the provision of the decrypted multimedia content to the user device, a first securer for executing security services having a first associated level of security and a second securer for executing services having an associated level of security lower than the first level of security. The device includes a hypervisor able to control the execution of at least three groups of virtual machines, the groups of virtual machines being executed in a strictly separate manner, including, the first two groups being dedicated to executing services with a level of security lower than the first level of security and the third group of virtual machines able to implement security services with a first level of security and to act as trusted third parties for services of the first and second groups of virtual machines.

Abstract: A method for measuring an audience of peers of a television channel streamed over a peer-to-peer network includes connecting at least one monitored peer to the peer-to-peer network and sending by the at least one monitored peer a request to at least one neighboring peer of the peer-to-peer network. There is an identifier of the at least one neighboring peer contained in its own list of neighboring peers. In reply to the request, receiving by the at least one monitored peer a list of neighboring peers receiving the television channel streamed over the peer-to-peer network and containing for this purpose, in their respective buffer memory, chunks of the television channel likely to be downloaded by any one of the peers of the peer-to-peer network. The method also includes updating by the at least one monitored peer of its own list of neighboring peers by adding to this list the identifiers of neighboring peers present in the list received and which were not already present in its own list of neighboring peers. The method further includes constructing the audience measurement from the list of neighboring peers of the at least one monitored peer.
