The disclosure relates to a method for configuring an WLAN (Wireless Local Area Network) access point adapted to use at least one operational frequency channel to transmit or receive data when the access point is in an operational mode. The configuring includes checking an availability of at least one restricted frequency channel, a use of the restricted frequency channel being restricted by the availability, choosing the operational frequency channel from a set of frequency channels according to the checked availability, a first configuring comprising a first checking of restricted frequency channels belonging to a first proper sub-set of the set being performed before entering into the operational mode. At least one second checking of at least one restricted frequency channel of the set, that has not been checked as available, is performed after the first configuring.

A method adapted to be implemented in a master device of a distributed sound system is described. The master device includes a plurality of audio input interfaces and is adapted to output audio signals on a set of at least two audio channels. According to an embodiment of the disclosure, the method includes detecting at least one audio signal conveyed by at least one of the audio input interfaces; routing the conveyed signal to at least one of the audio channels, the routing taking into account a number of detected audio signals. A corresponding master device, system, computer readable program product, and computer readable storage medium are also described.

The invention relates to a method for controlling a device operating in several operating modes corresponding to different levels of power consumption and comprising a first and a second communication interface, said method being characterized in that it comprises the steps of activating said second communication interface upon receiving a first wake-up message via said first interface and receiving a second wake-up message via said second communication interface, said second wake-up message resulting in the exit from the low-power standby mode of the device.

Method for exiting a low-consumption standby mode, and associated device

The current invention relates to the reuse of elements in an device to provide multiple functions of function indication, remote control command reception and touch sensor. 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.

Multiple function arrangement for electronic apparatus and method thereof

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.

Method for using a remote control for a payment transaction and associated device

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.

Apparatus and method for signature verification

The present invention relates to a system and a method of memory management of data consistency relating to a main memory ( ) accessible by at least two processors ( ), as well as an associated multiprocessor network. The management system comprises an assembly for management of shared access of the processors to a common area ( ) of the main memory, referred to as the exchanges area, at least one copy module ( ) intended for performing a data copy between at least one first processor comprising at least one cache memory and the exchanges area and at least one transfer module ( ) intended for performing a transfer of data between the exchanges area and at least one second processor. Triggering means controlled by the second processors trigger the copy modules and transfer modules when the first processors submit requests involving transfers of data between the first and second processors.
