    摘要： The invention relates to pairing a slave device with a master device, for example decoders in a conditional access system. There is provided a security module that stores a device state that indicates whether a decoder shall be a master or a slave decoder. There is also provided a method in a conditional access system of providing a device with a device state stored on a security module. It is detected that the security module is in connection with the device and the device state is transferred from the security module to the device. There is further provided a method of pairing a slave device with a master device. The slave device asks the master device to identify itself, the master device returns an identification, and if the slave device has not yet been paired with a master device, it checks the identity of the master device and, if the identity is verified pairs with the master device. There is also provided a first, slave, device for pairing with a second, master, device. The first device comprises an interface for sending an identification command to and receiving an identification message from the master device, and a processor for checking the identity of the second device and pairing the first device with the second device.

    摘要： The invention relates to a process for controlling digital rights of the “Play N times” type for a digital audio and/or video content (132), referred to as controlled content (132), the controlled content being consumed by a consumer on a consuming device (112) or on another device delegating the controlling of these rights to the consuming device. According to the invention, such a process is characterized in that charging of one additional usage is inhibited in at least one of the following cases where: the consumer momentarily consumes another content, on the same device (112) where the controlled content (132) is consumed, and then returns to the controlled content (132), the consumer effects a pause in the usage of the controlled content (132), the consumer performs a fast-forward of the controlled content (132), the consumer performs a rewind of the controlled content (132).

    摘要： In a method for managing a Certificate Revocation List (CRL), a first device (31, 61) receives the CRL (33, 67) which comprises at least one revoked certificate identifier (SNi). An integrity field (MACi) associated to an entry of the CRL (371, . . . , 37p) is calculated using a secret data (KCRL), wherein an entry comprises at least one revoked certificate identifier of the CRL. The entry and its associated calculated integrity field are transmitted to a second device (32, 62), distinct from the first device and are stored into the second device. The method further comprises checking a validity of a certificate.

    摘要： A method of processing digital content according to a workflow. The digital content is received and information for the workflow is checked to decide if a processing device is authorized to process the content, the workflow imposing that the digital content be processed in a process chain comprising at least two nodes, wherein the processing device is authorized to process the content if it corresponds to the node that according to the process chain is the next node to process the digital content. If the processing device is authorized to process the content, the digital content is processed and the information for the workflow is updated. Also provided is a system.

    摘要： A method for preventing the bypassing of watermark embedding in a bit-stream representative of audio/video data is disclosed. The method is remarkable in that it comprises a step of corrupting the bit-stream wherein original blocks in the bit-stream are replaced by corrupted blocks producing a non-compliant bit-stream; and a step of repairing the corrupted bit-stream by replacing each corrupted blocks, wherein at least one corrupted block is replaced by a watermarked block and at least one corrupted block is replaced by an original block, producing a compliant repaired and watermarked bit-stream. A device for watermarking and repairing a corrupted bit-stream and to a device for preparing a corrupted bit-stream, wherein the original bit-stream is representative of audio/video data are further disclosed.
