Abstract: The invention relates to a method of determining latency information in a wireless audio system, the wireless audio system comprising at least one wireless receiver, a wireless transmitter and a sound recorder, the method comprising the following steps: transmitting at least one test signal from the wireless transmitter to the wireless receiver, the test signal defining a time reference; playing the test signal at the wireless receiver; acquiring an audio record by the sound recorder during the test signal is played by the wireless receiver; determining, by the sound recorder, a latency information related to the wireless receiver at least based on the time reference and based on the audio record, the wireless transmitter and the sound recorder being synchronized; transmitting the determined latency information to the wireless transmitter.

Abstract: A control device of voice distribution including: at least one voice processing module arranged to—receive as input an audio signal including a first vocal message, and—provide as output an audio signal including a second vocal message, the first and second vocal messages being different one from the other and the second vocal message resulting from a processing of the first vocal message; a communication module arranged to establish and simultaneously manage a wireless, bidirectional and audio link with each one of a plurality of auxiliary devices, each link being connected to the input and/or the output of at least one voice processing module.

Abstract: Disclosed is a device for controlling Bluetooth multimedia devices, the device including a Bluetooth chip configured to establish a point to multipoint link from the Bluetooth chip to a plurality of Bluetooth multimedia devices, and to stream a multimedia stream to at least one of the plurality of Bluetooth multimedia devices. The Bluetooth chip is further configured to: retrieve from each Bluetooth multimedia device an indication of a signal strength of each link between the device and the corresponding Bluetooth multimedia device; and select at least one Bluetooth multimedia device to which stream the multimedia stream based on the retrieved indications of signal strength.

Abstract: Disclosed is a device (DEV) for controlling Bluetooth multimedia devices, the controlling device including a Bluetooth chip (BC) arranged to implement a modified A2DP profile (A2DP?) so as to create a point-to-multipoint link (LNK) from the Bluetooth chip to several Bluetooth multimedia devices (SPK1, SPK2, SPKN), the Bluetooth chip of the controlling device being arranged to stream several interconnected multimedia streams, each to a respective Bluetooth multimedia device from among the several Bluetooth multimedia devices, based on a non-blocking Bluetooth usage. The description also refers to a method for controlling Bluetooth multimedia devices, to a computer program arranged to implement such a method as well as to a storage medium storing such a computer program.

Abstract: Disclosed is a device for controlling wireless multimedia devices, including: a wireless communication circuit, to receive a wireless multimedia device identifier from each wireless multimedia device; an access circuit for accessing a database of wireless multimedia devices, to obtain from the database characteristics of each wireless multimedia device for which the communication circuit has received an identifier; a separation circuit for separating a main multimedia stream into as many separated multimedia streams as the communication circuit has received identifiers of wireless multimedia devices; an allocation circuit for allocating each separated multimedia stream to a respective wireless multimedia device; and a synchronization circuit for synchronizing the separated multimedia streams based on the characteristics of the wireless multimedia devices obtained from the database.
