Abstract: A method for controlling an operating parameter of an acoustic apparatus, including implementing a screen displaying at least one window including a cursor able to occupy positions relative to a reference of the window, the positions representing values of the operating parameter between a minimal and a maximal value, displaying the cursor in an initial position relative to the reference representative of an initial value of the operating parameter, acquiring an elementary command from an operator, moving the cursor with respect to the reference as a function of the elementary command, from the initial position to a final position in order to select a final value of the operating parameter in a range of selectable values containing the initial value, and sending the selected value to the acoustic apparatus, wherein the range of selectable values has an amplitude strictly less than the difference between the maximum and the minimum values.

Abstract: The present invention concerns a synchronization method for synchronizing at least two systems for rendering multimedia streams, the method comprising: the detection of a pulse of a same signal of fixed frequency by each rendering system and by a main clock system, the generation of a main clock signal and a dependent clock signal, the estimating of a main local date of reception of the subsequent pulse and a dependent local date of reception of the subsequent pulse, the calculation of the difference between the main local date and the dependent local date, the iteration of the preceding steps until a first condition concerning the calculated differences is met, the receiving of a multimedia stream, by each of the rendering systems, the sending of a rendering date, and the calculation of an effective date for the rendering of the multimedia stream.

Abstract: The invention relates to a method implementing at least one loudspeaker comprising at least one module suitable for generating a value representative of an internal operation of the loudspeaker, and a memory unit for storing an alarm criterion relative to the generated value, and control software for controlling the loudspeaker. The method further comprising the steps of the module produces a value representative of the internal operation of the loudspeaker, the loudspeaker compares the generated value and the alarm criterion, and the loudspeaker emits a sound or visual signal if the result of the comparison indicates that the generated value fulfills the alarm criterion.

Abstract: An assembly of electronic devices connected to a computer network comprises a digital data sender device comprising a short-range radioelectric main communication module and a secondary communication module, and a digital data receiver device comprising a short-range radioelectric main communication module and a secondary communication module. The assembly furthermore comprises a digital data transmitter device comprising a processor, a memory for storing the digital data, and a short-range radioelectric communication module able to communicate with the secondary module of the sender device when the transmitter device is in proximity to the sender device, and with the secondary module of the receiver device when the transmitter device is in proximity in the receiver device.

Abstract: Devices connected to a remote unit, each device storing at least one identifier of the device, and at least one configuration parameter representative of a configuration of the device, and a control set adapted for remotely controlling the devices, the control set comprising an interface. The method comprises selecting, by a user, any of the configuration parameters by the interface, detecting, by the control set, that the configuration parameter is selected and providing an identification parameter of the device corresponding to the configuration parameter.
