Abstract: The Bluetooth device (DEV) controlling a plurality of wireless audio devices, comprises: a wireless communication circuit, to receive a wireless audio device identifier from each wireless audio device; a sound processing circuit to apply independent audio effects on a main audio stream such that the sound processing circuit outputs as many modified audio streams as the wireless communication circuit has received identifiers of wireless audio devices, on the basis of the characteristics of each wireless audio device; an allocation circuit to allocate each modified audio stream to a respective wireless audio device, a transmission circuit to wirelessly transmit through a Bluetooth usage each modified audio stream to said respective wireless audio device for emission by the wireless audio devices.

Abstract: Disclosed is a device for controlling a dual-mode Bluetooth low energy multimedia device, the dual-mode BLE multimedia device including a first sound system and a second sound system which are arranged to simultaneously stream an input multimedia stream, the first and second sound systems being respectively associated with at least one first Bluetooth multimedia device and at least one Bluetooth multimedia device. Also disclosed is a dual-mode Bluetooth low energy multimedia device, a method, a computer program and a non-transitory computer-readable storage medium.

Abstract: A method of synchronizing sub-systems each including a master device and at least one slave device connected to the master device via Bluetooth for playback by the at least one slave device of audio data. The method includes collecting respective internal latency data of the sub-systems, determining, based on the internal latency data of the plurality of sub-systems, respective delays to be applied by the sub-systems between reception of the audio data and playback of the audio data by the slave devices of the sub-system, and, by each sub-system, applying the corresponding delay for playback of the audio data.

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.
