[0017] Figure 1 is a schematic diagram of the structure of a Bluetooth low energy audio conferencing system in an embodiment of the present invention;
[0018] Figure 2 It is a flow chart of a data processing method for a Bluetooth low energy audio conferencing system in an embodiment of the present invention. DETAILED DESCRIPTION
[0019] 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.
[0020] Reference Figure 1 , a schematic diagram of the structure of a Bluetooth low energy audio conferencing system in an embodiment of the present invention is given, Figure 2 A flowchart of a data processing method for a Bluetooth low energy audio conferencing system in an embodiment of the present invention is given. Figure 1 and Figure 2 A data processing method for a Bluetooth low energy audio conferencing system (hereinafter referred to as the data processing method) is described in detail.
[0021] In a specific implementation, the Bluetooth low energy audio conferencing system includes multiple audio transceiver devices, each of which supports the Bluetooth low energy audio mode.
[0022] Each audio transceiver device supports the Broadcast Isochronous Streams (BIS) mode. In BIS mode, each audio transceiver device can broadcast signals to other audio transceivers and send sound data through broadcasting. Other audio transceivers scan the broadcast signal to listen to obtain sound data and play it.
[0023] Furthermore, each audio transceiver device may also support a Connected Isochronous Streams (CIS) mode. A connection is established between multiple audio transceivers, and after the connection is established, the multiple audio transceivers can transmit sound data through a dedicated channel, thereby improving data transmission security.
[0024] In a specific implementation, the audio transceiver device may be a device with voice collection function and audio playback function, such as a speaker, earphone, microphone, laptop computer, tablet, etc. This application does not limit the specific performance style of the audio transceiver device.
[0025] In a specific implementation, the data processing method is applied to the audio transceiver device, that is, the data processing method can be executed by the audio transceiver device. The data processing method can specifically include the following steps:
[0026] Step 11: Scan the broadcast signal while listening to the current broadcast signal.
[0027] Step 12: determining a target broadcast signal from the scanned broadcast signals according to a preset listening rule, wherein the target broadcast signal is a broadcast signal that can interrupt the current broadcast signal.
[0028] Step 13: switch to the target broadcast signal and listen to it.
[0029] In a specific implementation, the listening rule includes listening to the broadcast signal according to the priority from high to low.
[0030] In step 12, it is determined whether there is a broadcast signal with a higher priority than the current broadcast signal among the scanned broadcast signals; when there is a broadcast signal with a higher priority than the current broadcast signal, the broadcast signal with a higher priority than the current broadcast signal is used as the target broadcast signal.
[0031] Accordingly, when there is no broadcast signal with a higher priority than the current broadcast signal, the scanned broadcast signal is ignored and the scanning of broadcast signals continues.
[0032] In some embodiments, the priority of the broadcast signal can be preconfigured. The priority of the broadcast signal represents the priority of the audio transceiver device. The speech of the participant corresponding to the audio transceiver device with a higher priority is more likely to be heard by other audio transceivers, and then heard by the participants of other audio transceivers.
[0033] In some non-limiting embodiments, the priority of the audio transceiver device can be configured according to the location of the audio transceiver device. For example, the audio transceiver device located at the host's position has the highest priority, and the audio transceiver device located in the general participant area has the lowest priority. It should be noted that the method for determining the priority of the audio transceiver device is not limited to the above example. In practice, the venue can be divided into multiple areas according to the location layout, and the audio transceiver devices in different areas can be configured with corresponding priorities respectively.
[0034] In some embodiments, the configuration can be performed based on the participants who use the audio transceiver device. Usually, the speech status of the participants in the meeting can be known in advance, and the priority of the participants can be determined based on the seating arrangement of the participants. For example, the priority of the audio transceiver device of the management participant is higher than the priority of the audio transceiver device of the ordinary employee participant.
[0035] In a specific implementation, each audio transceiver device has a corresponding tag, and the tag uniquely corresponds to the audio transceiver device. The tag of the audio transceiver device can be carried in the broadcast signal or in the broadcast name. The tag can be used to know the audio transceiver device from which the broadcast signal comes, and then the priority of the audio transceiver device can be known.
[0036] For example, in a typical conference scenario, the venue includes a host area, a speaker area, and an ordinary participant area. The priority of the audio transceiver equipment in the host area, the priority of the audio transceiver equipment in the speaker area, and the priority of the audio transceiver equipment in the ordinary participant area decrease in sequence.
[0037] For another typical conference scenario, the identities of participants are not distinguished in the conference room, each participant can speak freely, and each audio transceiver has the same priority.
[0038] In a specific implementation, a conference identifier may be agreed upon in advance for the conference system, and the conference identifier may be a conference name, a conference number, a designated character, and the like.
[0039] In some embodiments, the conference identifier may be carried in the broadcast signal. After the listening device scans the broadcast signal, the conference identifier may be obtained from the broadcast signal.
[0040] In some other embodiments, the conference identifier may be carried in the broadcast name. The conference identifier is obtained from the broadcast name of the received broadcast signal.
[0041] In a specific implementation, the conference identifier is used to determine whether the broadcast signal is sent by an audio transceiver device belonging to the conference system. If it is not sent by an audio transceiver device belonging to the conference system, it is ignored. If it is sent by an audio transceiver device belonging to the conference system, the target broadcast signal is determined. In this way, the conference security can be improved.
[0042] In some non-limiting implementations, when there is a broadcast signal with a higher priority than the current broadcast signal, the broadcast signal with a higher priority than the current broadcast signal is used as the target broadcast signal.
[0043] In other non-limiting implementations, when there are multiple broadcast signals with higher priorities than the current broadcast signal, according to the number N of broadcast signals listened to simultaneously, M broadcast signals are selected from the broadcast signals with higher priorities than the current broadcast signal in descending order of priority as the target broadcast signals, wherein M and N are both positive integers and M≤N.
[0044] For example, when there are three broadcast signals with higher priorities than the current broadcast signal, and the number of broadcast signals listened to simultaneously is two, the broadcast signals with the highest priority and the second priority are selected from the broadcast signals with higher priorities than the current broadcast signal as the target broadcast signals.
[0045] For another example, when there are two broadcast signals with higher priorities than the current broadcast signal, and the number of broadcast signals listened to simultaneously is four, the two broadcast signals with higher priorities than the current broadcast signal are used as the target broadcast signals.
[0046] In a specific implementation, the number N of broadcast signals listened to simultaneously may be obtained from the listening rule. The number N of broadcast signals listened to simultaneously may be preconfigured.
[0047] In specific implementation, the listening rules can be dynamically adjusted according to the conference session, and each conference session has corresponding listening rules.
[0048] In some non-limiting embodiments, the listening rule may be configured in the following manner: obtaining the conference session of the current conference; and determining the listening rule based on the conference session.
[0049] In specific implementation, the conference sessions may include a host speech session, a designated spokesperson speech session, a free discussion session, etc. The types of conference sessions included in each meeting and the layout of each conference session are configured according to actual meeting needs.
[0050] The conference session is the host's speech session, and the corresponding listening rule can be that the host's audio transceiver device has the highest priority, and the broadcast signal sent by the host's audio transceiver device can interrupt the broadcast signals sent by all other audio transceiver devices. At this time, the broadcast signal listened to by the listening device comes from the host's audio transceiver device, and all audio transceiver devices play the voice of the host.
[0051] The conference session is a speech session for a designated speaker, and the corresponding listening rule may be that the audio transceiver device of the designated speaker has the highest priority, or the audio transceiver device of the designated speaker and the audio transceiver device of the host have the same priority, or the priority of the audio transceiver device of the designated speaker is only lower than the priority of the audio transceiver device of the host.
[0052] The conference session is a free discussion session, and the corresponding listening rules can be that the audio transceiver devices of all participants have the same priority, or the audio transceiver device of the host has the highest priority, and the audio transceiver devices of participants other than the host have the same priority. Broadcast signals of the same priority can interrupt the current broadcast signal so that participants can speak freely and their speeches can be heard by other participants. Furthermore, the conference rules can also include disconnecting the current broadcast signal if the current broadcast signal does not broadcast data for a preset period of time, so that the broadcast signals sent by other audio transceiver devices can be heard by the listening device in a timely manner.
[0053] The central control device determines the conference link according to the current time. For example, each conference link can be configured with a corresponding time period, and the current conference link is determined according to the current time.
[0054] The central control device obtains conference keywords from the target broadcast signal and determines conference links according to the conference keywords.
[0055] For example, extract the information "Zhang San will speak next" from the target broadcast signal, and determine the meeting session as the designated speaker speech session based on the conference keyword "Zhang San speaks". For another example, extract the information "Let's discuss freely now" from the target broadcast signal, and determine the meeting session as the free discussion session based on the conference keyword "free discussion".
[0056] In a specific implementation, when a team request operation is detected to be triggered, team request information is obtained; the team request information is carried in a broadcast signal and sent out, and the team request information includes the identifier of the audio transceiver device that initiates the team request and the identifier of the audio transceiver device to be added to the team; team confirmation is received, and a group and a listening rule for the group are created based on the team confirmation, and the team confirmation is sent by the audio transceiver device to be added to the team in response to the broadcast signal carrying the team request information.
[0057] The team formation request can be triggered by voice. Users can configure team formation information by voice. For example, the participant pairs audio transceiver device A, and the participant sends voice to form a team with audio transceiver device B and audio transceiver device C.
[0058] The team formation request can also be triggered by pressing a button, and the specific content of the team formation request information can be pre-configured when the button is pressed.
[0059] The listening rule includes that the priority of the broadcast signal sent by the audio transceiver device belonging to the same group is higher than the broadcast signal sent by other audio transceiver devices, and based on the group identifier in the scanned broadcast signal, the broadcast signal belonging to the same group as itself is used as the target broadcast signal.
[0060] When there are multiple broadcast signals belonging to the same group as the user, the user can select a broadcast signal from the broadcast signals belonging to the same group as the user as the target broadcast signal according to the listening rule of the group. The listening rule of the group includes any of the following: listening to multiple broadcast signals in the group at the same time; listening to the first received broadcast signal belonging to the same group as the user according to the reception time of the broadcast signal.
[0061] When the duration for which no audio data is listened to from the current broadcast signal reaches a preset duration, listening to the current broadcast signal is interrupted.
[0062] In a specific implementation, the broadcast signal is an encrypted broadcast signal. The audio transceiver device belonging to the conference system knows the decryption key of the encrypted broadcast signal and can use the decryption key to decrypt the encrypted broadcast signal. Even if the audio transceiver device that does not belong to the conference system receives the encrypted broadcast signal, it cannot decrypt the encrypted broadcast signal because it does not have the decryption key, thereby improving communication security.
[0063] It can be seen from the above scheme that each audio transceiver device supports Bluetooth low energy audio mode, and each audio transceiver device can scan the broadcast signal while listening to the current broadcast signal. According to the preset listening rules, the target broadcast signal is determined from the scanned broadcast signals. The target broadcast signal is a broadcast signal that can interrupt the current broadcast signal. Switch to the target broadcast signal and listen. In this way, you can flexibly switch between multiple broadcast signals according to actual meeting needs to listen to the speeches of different participants, thereby improving the diversity of meeting functions.
[0064] In addition, compared with the existing wired conference system or WIFI-based conference system, the conference system provided by the present application, which is composed of audio transceiver devices based on the Bluetooth low-power audio mode, has strong anti-interference ability, wide coverage, simple deployment, and easy use. The Bluetooth low-power audio mode uses a low-complexity communications codec (LC3) encoding scheme for sound data transmission, which has higher sound quality.
[0065] The present invention also provides a Bluetooth low-power audio conferencing system, comprising a plurality of audio transceiver devices, each of which supports a Bluetooth low-power audio mode, and each of which uses a data processing method provided in any of the above embodiments.
