In another possible implementation, the target bluetooth broadcast parameter may be a default broadcast parameter for a display device in the display system. The control terminal can acquire default broadcast parameters of the display device through interaction with the display device.

When the control end determines the target Bluetooth broadcasting parameters, the control end can configure the target Bluetooth broadcasting parameters for each display device in the display system.

For example, the control end may configure the target bluetooth broadcast parameters for each display device when each display device is turned on. For example, the control end may determine whether each display device in the display system is powered on according to a heartbeat detection mechanism, and after confirming that the display is powered on, configure the target bluetooth broadcast parameters for each display device.

In one possible implementation manner, the control end may also configure a target bluetooth broadcast parameter for each display device when detecting that each display device starts broadcasting.

In one possible implementation manner, when the target bluetooth broadcast parameter is a default broadcast parameter of a certain display device in the display system, the control end may acquire the bluetooth broadcast parameter in advance, or acquire the target bluetooth broadcast parameter after the display device is started, and configure the target bluetooth broadcast parameter for other display devices.

It should be understood that, in the display system, the audio sources broadcast by each display device are the same, which may be stored in the local storage of each display device in advance, or may be sent to each display device by the control end when configuring the target bluetooth broadcast parameters.

S502, controlling the display equipment to synchronously broadcast target audio by using the target Bluetooth broadcasting parameters.

In the embodiment of the application, when the control end configures the target Bluetooth broadcasting parameters for each display device, the control end can control the display device to synchronously broadcast the target audio by using the target Bluetooth broadcasting parameters.

In one possible implementation manner, after each display device is started, the control end can control the display devices in the display system to synchronously broadcast the target audio by using the target bluetooth broadcast parameters in a mode of mass-sending broadcast instructions. I.e. the one that is the one. Each display device may begin broadcasting target audio at the same time using the same target bluetooth broadcast parameters. In this way, the broadcasting schedule of each display device, and the channel on which the target audio is broadcast are the same. After receiving the broadcast audio through the access channel in the broadcast coverage of any one display device, the audio receiving device can continuously listen to the corresponding broadcast audio through the same channel when moving to the broadcast coverage of the other display device. The operation such as scanning and connection is not needed again, the method is simple and convenient, and the use experience of a user is high.

In one possible implementation, the display devices are turned on at different times, and a portion of the display devices in the display system may broadcast audio earlier than another portion of the display devices. That is, broadcasting schedules of different display devices are different. In this case, the control end may determine the broadcasting progress of each display device according to the target bluetooth broadcasting parameter and the current time, and adjust the broadcasting progress of each display device to the same progress.

It should be understood that in the embodiment of the present application, controlling the display device to synchronously broadcast the target Audio using the target bluetooth broadcast parameter is performed based on the LE Audio protocol, and the synchronously broadcast target Audio may include a plurality of Audio tracks.

The following briefly describes broadcasting target Audio according to the LE Audio protocol with reference to fig. 5 b:

for example, when broadcasting according to the LE Audio protocol, the control end may take BIG event (BIG event) as a unit when controlling each display device to send a broadcast Audio stream, as shown in fig. 5b, and after each time the Audio stream in BIG event x is sent, the control end switches to send the Audio stream in BIG event x+1 sequentially. The period of time occupied by each BIG event may be referred to as an isochronous interval iso_interval, where a BIG Anchor Point exists between two consecutive BIG events, for determining the demarcation Point between two BIG events.

One BIG event may include a plurality of BIS events, where each BIS event is configured to carry an audio stream corresponding to one audio track in one target audio.

According to the audio broadcasting method provided by the embodiment of the application, the target Bluetooth broadcasting parameters are configured for the display equipment, so that the display equipment is controlled to synchronously broadcast target audio by using the target Bluetooth broadcasting parameters. By the above method, the broadcasting progress of each display device and the channel of the broadcasting target audio can be the same. After receiving the broadcast audio through the access channel in the broadcast coverage of any one display device, the audio receiving device can continuously listen to the corresponding broadcast audio through the same channel when moving to the broadcast coverage of the other display device. The operation such as scanning and connection is not needed again, the method is simple and convenient, and the use experience of a user is high.

Optionally, on the basis of the foregoing embodiment, the audio broadcasting method provided by the embodiment of the present application may configure the target bluetooth broadcasting parameters for each display device according to the following manner.

Illustratively, in response to a target operation of the display device, sending a configuration instruction to the display device, the configuration instruction being for configuring the target bluetooth broadcast parameter; the target operation comprises a starting operation and a broadcasting starting operation of the display equipment.

The control end can detect state changes of all display devices in the display system, and when the state changes of the display devices indicate the display devices to execute the target operation, the control end can configure the target Bluetooth broadcast parameters in a mode of sending configuration instructions to the display devices, wherein the configuration instructions can comprise the target Bluetooth broadcast parameters, so that all the display devices take the target Bluetooth broadcast parameters as broadcast parameters when the broadcast audio is executed.

When the control end detects that the state of the display device is changed from off to on, the control end can confirm that the display device executes the on operation, and then the control end can send a configuration instruction to the on display device, so that the on display device takes the target Bluetooth broadcast parameter as a broadcast parameter of the control end according to the configuration instruction. Or when the control end detects that the non-broadcast of the display device is changed from shutdown to broadcast, the control end can confirm that the display device executes the broadcast starting operation, and then the control end can send a configuration instruction to the display device which is started, so that the display device takes the target Bluetooth broadcast parameter as the own broadcast parameter according to the configuration instruction. Through the operation, the mode of configuring the target Bluetooth broadcast parameters to each display device by the control terminal can be more flexible, and the probability of configuration failure possibly existing in a single configuration mode is reduced.

It should be understood that the broadcast start operation of the display device may be performed based on a broadcast instruction of the control end, or may be performed based on an operation instruction of the user, which is not limited in the embodiment of the present application.

Optionally, on the basis of the foregoing embodiment, the audio broadcasting method provided by the embodiment of the present application may acquire the target bluetooth broadcasting parameter according to the following manner.

Illustratively, receiving the target bluetooth broadcast parameters input by a user; or, taking the Bluetooth broadcasting parameter of the display device which broadcasts the target audio earliest in the display system as the target Bluetooth broadcasting parameter; or determining the target Bluetooth broadcasting parameters from a preset Bluetooth broadcasting parameter library.

In one possible implementation manner, the control end may be provided with a front end page for interacting with a user, and the control end may display a target bluetooth broadcast parameter input interface based on an instruction of the user, and respond to an input operation of the user in the interface to obtain the target bluetooth broadcast parameter. Or, the target bluetooth broadcast parameter input interface is preset with a plurality of candidate bluetooth broadcast parameters, and the target bluetooth broadcast parameters are obtained in response to the selection operation of the user in the interface.

In one possible implementation manner, each display device in the display system has a default bluetooth broadcast parameter, the display system may acquire the default bluetooth broadcast parameter of each display device, and a time stamp of broadcasting the target audio by each display device, according to the time stamp, the display device that broadcasts the target audio earliest may be determined, and the default bluetooth broadcast parameter of the display device that broadcasts the target audio earliest is taken as the target bluetooth broadcast parameter.

In one possible implementation, the display system has a preset bluetooth broadcast parameter library. The control end can select target Bluetooth broadcasting parameters from a preset Bluetooth broadcasting parameter library according to preset conditions. For example, the preset condition may be an identification of the target audio, a display system identification, or the like. The preset bluetooth broadcast parameter library may be stored in a storage space of the control end, or may be stored in a database, which is not limited in the embodiment of the present application. By the mode, flexibility of acquiring the target Bluetooth broadcast parameters can be improved, and accordingly efficiency of broadcasting audio is improved.

Optionally, on the basis of the foregoing embodiment, in the audio broadcasting method provided by the embodiment of the present application, if the broadcasting progress of each display device in the display system is inconsistent, the control end may adjust the broadcasting progress of each display device in the display system according to the following manner.

For example, if the display device is not the first device broadcasting the target audio in the display system, the target information is sent to the display device, where the target information is used to determine the progress of the first device broadcasting the target audio, so that the display device in the display system synchronously broadcasts the target audio.

The control end can record a time stamp of each display device broadcasting by using the target Bluetooth broadcasting parameters, and according to the time stamp, if the control end determines that the time of broadcasting of each display device is inconsistent, the control end can determine the progress of broadcasting the target audio by the first display device broadcasting the target audio according to the time stamp and the current time. And the control end sends the target information comprising the progress to a display device which does not broadcast the target audio first, so that the display device adjusts the progress of the control end to the progress included in the target information. By the method, the broadcasting progress of each display device in the display system can be synchronized, so that the probability of receiving repeated content in the broadcasting coverage range of different display devices by the audio broadcasting device due to different broadcasting progress is reduced, and the use experience of a user is improved.

The description was given above of the audio broadcasting method applied to the display system including the control terminal, and the description will be given below of the audio broadcasting method applied to the display system not including the control terminal.

In a possible implementation manner, the embodiment of the application provides an audio broadcasting method, which is applied to display equipment in a display system, wherein the display system comprises a plurality of display equipment, bluetooth devices are built in the display equipment, and/or the display equipment is externally connected with at least one Bluetooth device, and Bluetooth broadcasting signal coverage areas among the display equipment are different or partially overlapped.

Fig. 6 is a flow chart of an audio broadcasting method according to an embodiment of the present application, as shown in fig. 6, including the following steps:

s601, when the Bluetooth device is used for broadcasting the audio, the time period occupied by the isochronous event interval on a broadcasting channel and the time period occupied by the BIG event in the isochronous event interval are acquired.

In the embodiment of the application, the audio sources broadcast by all display devices in the display system are the same, and the audio sources can be stored in the local storage of all display devices in advance.

First, a process in which the display apparatus broadcasts audio using the bluetooth device will be described.

The display device broadcasts audio using bluetooth low energy based periodic broadcast (Periodic Advertising) techniques that enable audio transmission over broadcast isochronous channels (BIG/BIS) where all information directed to the Broadcast Isochronous Group (BIG) is contained. As shown in fig. 7, when the display device broadcasts audio, an audio stream included in the audio to be broadcasted may be transmitted to a corresponding broadcast channel by means of a continuous BIG event (BIG event). Each BIG event may include a plurality of BIS events therein, and there are idle periods for two consecutive BIG events. Each BIG event together with a corresponding idle period constitutes a corresponding isochronous time Interval iso_interval. For example, BIG event1 in FIG. 7 and ISO_Interval, which collectively make up BIG event1 correspond.

For example, when the bluetooth device is used to broadcast audio, the display device may determine a duration corresponding to each iso_interval according to file information of the audio, where the file information includes a sampling rate, a track number, a channel number, an audio duration, and the like. And determining the duration corresponding to the BIG event according to the size of the audio stream to be broadcasted in the duration corresponding to each ISO_interval.

When the display device performs audio broadcasting, the period occupied by the iso_interval and the period occupied by the BIG event can be determined according to the current time, the period corresponding to the iso_interval and the period corresponding to the BIG event. For example, when the current time is 13:00, the duration corresponding to iso_interval is 10 seconds, and the duration corresponding to BIG event is 8 seconds, the period occupied by iso_interval is 13: the period of 00-13:01:10,BIG event is 13:00-13:01:08.

S602, determining an idle period in the time length of the isochronous event interval according to the time period occupied by the isochronous event interval and the time period occupied by the BIG event.

In the embodiment of the present application, when determining the period occupied by the iso_interval, and the period occupied by the BIG event, the display device may use, as the idle period, a period that is within the period occupied by the iso_interval and that is divided by the period occupied by the BIG event, for example, the period occupied by the iso_interval is 13: the period of 00-13:01:10,BIG event is 13:00-13:01:08, the idle period is 13:01:08-13:01:10.

It should be understood that the above time periods are only used to illustrate the difference between the time periods, and the duration corresponding to each time period may be much smaller than the above duration during actual broadcasting.

S603, broadcasting a bluetooth broadcast parameter used by the display device over the idle period of the broadcast channel.

For example, the display device may perform a packaging process on the used bluetooth broadcast parameters, and broadcast the packaged bluetooth broadcast parameters during the idle period.

As shown in fig. 8, the bluetooth broadcast parameter (simply referred to as a parameter) may be broadcast once every time the display device broadcasts audio (one BIG event).

In some embodiments, the display device broadcasts audio in a periodic broadcast manner, that is, the audio stream is transmitted in 40 radio frequency channels, wherein 37, 38, 39 are the primary broadcast channels. When broadcasting the bluetooth broadcast parameters, the display device may broadcast in a primary broadcast channel.

It should be understood that when the display device broadcasts audio, the audio may include a plurality of audio tracks, the display device may broadcast the audio tracks synchronously, different audio tracks may be broadcast in different channels, and fig. 8 is a schematic diagram of the broadcast audio including one audio track and broadcast parameters corresponding to the broadcast. That is, in one channel, each time a section of audio stream of the audio track is broadcast, the broadcast parameters corresponding to the audio track may be broadcast once, and the above procedure is repeated until the broadcasting of the audio stream included in the audio track is completed.

A brief description of how the audio receiving apparatus performs audio reception is provided below.

Taking a bluetooth headset as an example, when receiving broadcast audio for the first time, the bluetooth headset can scan the audio by means of a broadcast assistant in the intelligent terminal, a user can select a desired audio, and the intelligent terminal can synchronize the audio selected by the user into the headset. Meanwhile, the intelligent terminal can record the name of the audio selected by the user.

The Bluetooth headset can also receive and record Bluetooth broadcast parameters broadcast by the display device when receiving broadcast audio, and can feed back a change message to the intelligent terminal when confirming that the received Bluetooth broadcast parameters are changed in the moving process of the Bluetooth headset, and can start scanning in the background when the intelligent terminal receives the change message, and synchronously change the audio listened by the Bluetooth headset according to the recorded audio name so that the Bluetooth headset can continuously listen to the same broadcast audio.

In one possible implementation manner, after the public place mode is set in the intelligent terminal, the intelligent terminal can record the name of the audio selected by the user and the corresponding bluetooth broadcast parameter, if the public place mode is opened, the intelligent terminal can be always in a scanning state, if the corresponding signal strength is higher than the signal strength of the current accessed audio according to the bluetooth broadcast parameter when the new audio with the same name is scanned, the intelligent terminal can be accessed into the new audio, namely, the new audio is synchronized to the bluetooth earphone.

According to the audio broadcasting method provided by the embodiment of the application, when the Bluetooth device is utilized to broadcast audio, the time period occupied by the isochronous event interval on the broadcasting channel and the time period occupied by the BIG event in the isochronous event interval are obtained, and the idle time period in the isochronous event interval duration is determined according to the time period occupied by the isochronous event interval and the time period occupied by the BIG event, and Bluetooth broadcasting parameters used by the display equipment are broadcasted on the idle time period of the broadcasting channel. The broadcasting information of each display device is sent to the audio receiving device in a mode of broadcasting Bluetooth broadcasting parameters in an idle period, so that when the audio receiving device moves in the coverage range of different display devices, the audio receiving device can automatically and synchronously broadcast audio according to the received Bluetooth broadcasting parameters. The operation such as scanning and connection is not needed again, the method is simple and convenient, and the use experience of a user is high.

Optionally, on the basis of the foregoing embodiment, the audio broadcasting method provided by the embodiment of the present application may further determine the idle period in the following manner.

Illustratively, acquiring a time corresponding to a BIG anchor point of an isochronous event interval and a time corresponding to a BIG anchor point of a next isochronous event interval; determining the period occupied by the isochronous event interval according to the time corresponding to the BIG anchor point of the isochronous event interval and the time corresponding to the BIG anchor point of the next isochronous event interval; and determining the period occupied by the BIG event in the isochronous event interval according to the size of the audio stream broadcasted in the isochronous event interval.

As shown in fig. 7, the starting time point of each BIG event may be a corresponding BIG anchor point (BIG anchor point), when broadcasting audio, the display device may acquire the time at which all BIG anchor points are located, and according to the time at which two BIG anchor points are continuous and the time at which each BIG event is broadcast, the corresponding duration of the corresponding iso_interval and the period occupied by the iso_interval may be determined.

With continued reference to fig. 7, the duration corresponding to each BIG event may be composed of the duration of the BIS time included therein, the idle period between each BIS, and other information. Taking BIG event1 as an example, the display device may obtain a duration of each BIG event in BIG event1 and a duration corresponding to sub_interval, and obtain a period occupied by the corresponding BIG event according to the duration of each BIG event, the duration corresponding to sub_interval, and a time of broadcasting each BIG event.

According to the method, the BIG anchor point is used for determining the period occupied by the BIG event in the isochronous event Interval, so that the accuracy of determining the period occupied by the ISO_interval can be improved, and the period occupied by the BIG event is determined according to the duration of the BIS event, so that the accuracy of determining the period occupied by the BIG event can be improved, and the accuracy of confirming the idle period can be improved.

Optionally, on the basis of the foregoing embodiment, in the audio broadcasting method according to the embodiment of the present application, when the bluetooth broadcast parameters are broadcast in the idle period, the bluetooth broadcast parameters with corresponding sizes may also be broadcast according to the duration of the idle period. It will be appreciated that the more bluetooth broadcast parameters, the more space is occupied and the longer the duration required for broadcasting.

For example, if there is currently a broadcast parameter that is not broadcast over the idle period of the period occupied by the isochronous event interval on the previous broadcast channel, broadcasting the remaining broadcast parameters; if there is no broadcasting parameter which is not broadcasted in the idle period of the period occupied by the isochronous event interval on the previous broadcasting channel and the duration required for broadcasting the broadcasting parameter is longer than the duration of the idle period, segmenting the broadcasting parameter broadcasted at the time according to the duration of the current idle period and broadcasting the segmented broadcasting parameter; or, discarding broadcasting bluetooth broadcast parameters during the idle period; and if the broadcasting parameters which are not broadcasted in the idle period of the period occupied by the isochronous event interval on the previous broadcasting channel do not exist currently, and the duration required for broadcasting the broadcasting parameters is smaller than or equal to the duration of the idle period, broadcasting the Bluetooth broadcasting parameters.

When the display device broadcasts the bluetooth broadcast parameters, the required broadcast time period duration can be determined according to the size of the bluetooth broadcast parameters, and compared with the idle time period duration, the strategy of broadcasting the broadcast parameters can be determined.

Taking the first broadcast of the bluetooth broadcast parameter as an example, in one possible implementation (splitting policy), if the duration of the idle period is greater than or equal to the duration required for broadcasting the bluetooth broadcast parameter, the bluetooth broadcast parameter is broadcasted in the idle period. If the duration of the idle period is smaller than the duration required by broadcasting the Bluetooth broadcasting parameters, the display device can segment the Bluetooth broadcasting parameters according to the duration of the idle period and broadcast the segmented Bluetooth broadcasting parameters. The broadcasting duration required by the segmented bluetooth broadcasting parameters may be less than or equal to the duration corresponding to the idle period. The remaining bluetooth broadcast parameters may be broadcast in the next idle period.

It can be appreciated that, when the remaining bluetooth broadcast parameters are broadcast in the next idle period, the method is similar to that of the first broadcast of the bluetooth broadcast parameters, and will not be repeated here.

In one possible implementation (a waiting policy), the bluetooth broadcast parameters are broadcast during the idle period if the duration of the idle period is greater than or equal to the duration required to broadcast the bluetooth broadcast parameters. And if the duration of the idle period is smaller than the duration required by broadcasting the Bluetooth broadcasting parameters, the Bluetooth broadcasting parameters are abandoned from being broadcasted in the current idle period, and the arrival of the next idle period is waited.

In one possible implementation manner (mixing policy), if the duration of N idle periods continuously exists is smaller than the duration required for broadcasting the bluetooth broadcast parameters, the display device may change the policy for broadcasting the bluetooth broadcast parameters to a slicing policy, so as to reduce the probability that the bluetooth broadcast parameters cannot be broadcasted. Wherein, N can be determined according to actual demand.

By means of the above possible implementation manners, the success rate of broadcasting the bluetooth broadcast parameters can be improved.
