The device comprises an indicator element providing a first function of indicating to a user the operating state of the said device, a receiver element providing a second function of reception of remote control commands from a remote control device, means for combining the indicator element and the receiver element to provide a third function of touch sensor. The indicator element provides the first function during a subsequent second period of time and the receiver element providing the second function during the second of the time, the first and the second period of time being continuously alternated.

Abstract: Remote control device of a data receiver, the data being representative of an audiovisual content, the data receiver receiving information relating to payment of an object and data representative of the object, the remote control device comprising means of configuring the data receiver useful for processing data representative of an audiovisual content, remote control device being characterized in that it comprises a user interface for initializing a payment transaction, a first wireless interface for receiving information useful for payment of the object and a second wireless interface for transmitting payment information with a remote payment unit.

Abstract: A receiver comprises a security processor and a first memory that stores software code or second stage authentication key and a signature for the software or the second stage key. The receiver also stores a plurality of verification keys (PUAK). When the receiver is switched on or reset, the software or second stage key and the signature are loaded from the first memory. The security processor then loads a PUAK and uses it to verify the signature. In case of successful verification, the software code or second stage key is used and the verification method ends; it is then possible to activate CA specific functions in the receiver. However, if the verification is unsuccessful, then it is verified if there are untried PUAKs. If there are no untried signatures, then the verification has failed and the software cannot be verified; the verification method ends. If there are untried signatures, then the next PUAK is loaded.
