摘要： A device for presentation of a signal having an audio-visual content, comprising means for presenting said content, means for connecting to a transmission channel which is external with respect to said device for receiving a signal, and a module for transmission of a signal which is disposed in the same container together with the presentation means, comprising means for storing a first identification information, adapted to receive the signal from the connection means and to transmit said signal to the presentation means only when the first identification information corresponds to a second identification information contained in the signal. A system and method for presenting a signal comprising an audio-visual content are also disclosed.

摘要： Distinguishing between live and recorded content in a network comprising a rendering device, an access device, and a storage device. The rendering device broadcasts a message requesting devices in the network to respond if they diffuse a content, and sets a timer. The devices respond if they diffuse the content. The rendering device then determines that the content is: live, if it has received a response from the access device; recorded, if it has received a response from the storage device, but not from the access device; and illegal, if it has not received a response before time-out of the timer. There is further a “still live delay” after diffusion of the content during which the access device responds that it is diffusing the content, and following which it may send a content release message to the storage device that may then respond to request messages.

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： A method for distributing content in a content distribution system is disclosed which comprises the steps of: encrypting at a Content Packager a content using a content encryption key to generate an encrypted content; sending the content encryption key to a Licensing Authority; receiving from the Licensing Authority a distribution key containing an encryption of the content decryption key (Kc) for a given set of authorized devices; creating a secure link between the content encryption key (Kc) and the content protected by this content encryption key using a signature of the content; and distributing the encrypted content together with the signature of the content. A method for receiving content distributed according to the above-mentioned method in a device able to play back the content is also disclosed where the content signature is checked before any play back of the content.

摘要： A method for discovering emulated clients. A verifier sends a cryptographic challenge C to a client and preferably starts a timer. The client uses a deterministic key search algorithm to find the correct key and returns the result as a number of tries needed. The verifier then stops the timer if this was started and verifies that the result is correct and preferably that the response was timely. Also provided is a verifier.

摘要： A method for service delivery to a client, in which the client selects a service, and establishes a connection with a system server to which it sends an identity associated with the client and an identifier of the service. The system server verifies that the client is authorized to access to the service and that the client is non-emulated. If this is verified, the service is provided to the client. In a preferred embodiment, the service is scrambled content and the system server provides a descrambling key to the client, and instructs a content server to provide the scrambled content to the client. Also claimed are a device, a system, and a system server.
