[0020] In order to make the above-mentioned purposes, features and beneficial effects of the embodiments of the present invention more obvious and understandable, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] This application provides a processing center system for Bluetooth low energy audio, referring to Figure 1 and Figure 2 The processing center system of Bluetooth low energy audio includes: a Bluetooth low energy audio adapter matrix and a main controller 11. The Bluetooth low energy audio adapter matrix includes at least a plurality of broadcast isochronous audio streams (Broadcast Isochronous Streams, BIS) adapters (DONGLE) 12; the main controller 11 is in communication connection with the plurality of BIS adapters 12, and the main controller 11 distributes corresponding data to be distributed to the plurality of BIS adapters 12 respectively, and each BIS adapter 12 forwards the received data to be distributed to the corresponding terminal device.

[0022] In a specific implementation, multiple BIS adapters 12 can be connected to the main controller 11 in a variety of ways to communicate with each other for data transmission. For example, each BIS adapter 12 and the main controller 11 support USB connection, and each BIS adapter 12 is connected to the main controller 11 via a USB bus.

[0023] The terminal device and the BIS adapter 12 perform data transmission via the BLE link. Specifically, the BIS adapter 12 sends the data to be distributed in a broadcasting manner, and the terminal device receives the data to be distributed broadcasted by the BIS adapter 12 by monitoring the corresponding BIS adapter 12.

[0024] The terminal device at least supports the BIS mode and can monitor the corresponding BIS adapter 12 to receive the to-be-distributed data broadcasted by the BIS adapter 12. The terminal device supporting the BIS mode can be recorded as a BIS terminal device.

[0025] The data to be distributed broadcasted by each BIS adapter 12 can be listened to by multiple terminal devices. The terminal device can select a data transmission channel, and after determining the data transmission channel, it can listen to the data to be distributed broadcasted on the data transmission channel.

[0026] The BIS adapter 12 can identify the data channel through which it transmits data or the content of the transmitted data through the identification information.

[0027] In a typical scenario, the identification information may be the languages ​​supported by the BIS adapter 12, for example, BIS adapter 1 supports English, BIS adapter 2 supports French, and BIS adapter 3 supports Chinese. The terminal device can select the language and then select the BIS adapter to listen to. For example, if terminal device A selects Chinese, it will listen to BIS adapter 3. For another example, if terminal device B selects French, it will listen to BIS adapter 2. In this way, in the same meeting, the participant of terminal device A can listen to the Chinese conference content, and the participant of terminal device B can listen to the French conference content, so as to meet the personalized needs of different participants for different languages.

[0028] In a specific implementation, the main controller 11 distributes the data to be distributed to the multiple BIS adapters 12 respectively, and the data to be distributed distributed to at least two BIS adapters 12 are different. In this way, by configuring the BIS adapters 12 to distribute different data to be distributed respectively, it is possible to achieve simultaneous broadcasting of different data in multiple channels to meet the personalized needs of different participants.

[0029] In a specific implementation, the Bluetooth low energy audio adapter matrix may further include a plurality of connected isochronous streams (CIS) adapters 13, wherein the CIS adapter 13 is used to receive audio data. The main controller 11 is also used to distribute the audio data as the data to be distributed to the corresponding BIS adapter 12.

[0030] In a specific implementation, multiple CIS adapters 13 can be connected to the main controller 11 in a variety of ways to communicate with each other for data transmission. For example, each CIS adapter 13 and the main controller 11 support USB connection, and each CIS adapter 13 is connected to the main controller 11 via a USB bus.

[0031] The terminal device at least supports the CIS mode, and a private communication line is established between the terminal device and the corresponding CIS adapter 13, such as an asynchronous connection link (ACL) link connection between the terminal device and the corresponding CIS adapter 13, and data can be transmitted between the terminal device and the CIS adapter 13 that establish the private communication line. For example, the terminal device can send audio data to the corresponding CIS adapter 13 in the CIS mode. Correspondingly, the CIS adapter 13 can also send data to be distributed to the terminal device connected thereto.

[0032] In a specific implementation, the main controller 11 can transfer and exchange the audio data received by the CIS adapter 13 between other BIS adapters 12 and CIS adapters 13 according to actual needs.

[0033] In a specific implementation, the main controller 11 is further used to translate the audio data into translation data in a specified language, and distribute the translation data as the data to be distributed to the corresponding BIS adapter 12 .

[0034] For example, if the language corresponding to the audio data is Chinese and there are BIS adapters 12 corresponding to French and English, the Chinese audio data can be translated into French audio data and distributed to the French BIS adapter 12, and the Chinese audio data can be translated into English audio data and distributed to the English BIS adapter 12.

[0035] In a specific implementation, the main controller 11 determines the grouping information according to the CIS adapter 13 receiving the audio data or the terminal device from which the audio data comes, determines the CIS adapter 13 belonging to the group according to the grouping information, distributes the audio data as the data to be distributed to the CIS adapter 13 belonging to the group, and the CIS adapter 13 belonging to the group forwards the data to be distributed to the corresponding terminal device. In this way, the audio data can be sent to a specific terminal device in a targeted manner according to actual needs.

[0036] In some scenarios, there may be a need to send audio data only to specific terminal devices, without sending it to all terminal devices. For example, in a group discussion meeting, audio data is sent only between terminal devices belonging to the same group. For another example, in a large international conference, terminal devices can be grouped according to language, and the terminal devices belonging to the same group receive the same language. At this time, the terminal devices can be grouped, and the terminal devices belonging to the same group have a mark representing the group. The mark used to represent the group can be carried in the audio data. The CIS adapter 13 corresponding to the terminal devices belonging to the same group has a corresponding group.

[0037] When at least two CIS adapters 13 receive audio data, the main controller 11 determines the BIS adapter 12 and / or CIS adapter 13 corresponding to the CIS adapter 13 receiving the audio data, and distributes the audio data as the data to be distributed to the BIS adapter 12 and / or CIS adapter 13 corresponding to the CIS adapter 13 receiving the audio data.

[0038] In some scenarios, there may be multiple speakers. For example, when a speaker is speaking, there is a simultaneous interpreter translating the speaker's speech. At this time, the terminal device corresponding to the speaker collects audio data and sends it to the corresponding first CIS adapter, and the terminal device corresponding to the translator collects audio data and sends it to the corresponding second CIS adapter. Since the speaker's language and the translator's language are two different languages, the corresponding first CIS adapter and second CIS adapter may be two different CIS adapters. The first CIS adapter finds the corresponding BIS adapter based on the audio data, or the CIS adapter will distribute the audio data. The second CIS adapter finds the corresponding BIS adapter based on the audio data, or the CIS adapter will distribute the audio data.

[0039] It can be seen from the above scheme that the present application is configured with a Bluetooth low energy audio adapter matrix including at least multiple BIS adapters, the main controller 11 is communicatively connected with the multiple BIS adapters 12, the main controller 11 distributes corresponding data to be distributed to the multiple BIS adapters 12 respectively, and each BIS adapter 12 forwards the received data to be distributed to the corresponding terminal device. In this way, different contents to be distributed can be forwarded to multiple terminal devices at the same time according to actual meeting needs, and the synchronous forwarding and broadcasting of multi-channel information can be realized to meet the diverse needs in the meeting.

[0040] This application also provides a Bluetooth low energy audio conferencing system, referring to Figure 2 The Bluetooth low energy audio conferencing system includes: a plurality of terminal devices; and a processing center system of any of the above-mentioned Bluetooth low energy audio.

[0041] In a specific implementation, some of the multiple terminal devices support at least the BIS mode, and the other part supports at least the CIS mode. For example, a terminal device supporting the BIS mode can be recorded as a BIS terminal device, a terminal device supporting the CIS mode can be recorded as a CIS terminal device, and a terminal device supporting both the BIS mode and the CIS mode can be recorded as a BIS+CIS terminal device.

[0042] in, Figure 2In the figure, N BIS adapters, N CIS adapters, N BIS terminal devices, N CIS terminal devices and N BIS+CIS terminal devices are taken as examples for illustration. In practice, the number of BIS adapters, the number of CIS adapters, the number of BIS terminal devices, the number of CIS terminal devices and the number of BIS+CIS terminal devices can be configured separately and are not limited to the same number.
