Fig. 5c is a schematic diagram of 1 bluetooth speaker.

The technical scheme of the present application will be described in detail with reference to specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.

The embodiment of the application provides an audio broadcasting method which is applied to display equipment.

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, broadcasting first target audio on an audio broadcasting channel through the Bluetooth device.

In the embodiment of the application, the display device comprises a built-in bluetooth device, and/or the display device is externally connected with at least one bluetooth device, and the first target Audio broadcast by the display device on the Audio broadcast channel through the bluetooth device can be based on an LE Audio protocol.

The first target audio may be pre-stored in the display device, or may be obtained by the display device according to a preset condition, for example, obtained by downloading from a certain multimedia server according to a specific address. The embodiment of the application does not limit the mode of determining the first target audio.

One or more tracks may be included in the first target audio, and each track in the first target audio may correspond to one broadcast audio stream when the first target audio is broadcast. That is, a broadcast audio stream corresponding to one track is broadcast in one audio broadcast channel. The audio broadcasting channel may also be called an audio broadcasting channel or an audio broadcasting channel.

Taking the example that the first target Audio includes an Audio track, the following will briefly describe broadcasting the first target Audio according to the LE Audio protocol:

for example, when broadcasting according to the LE Audio protocol, the bluetooth device may send the broadcast Audio stream in units of BIG events (BIG event), as shown in fig. 7, and after each time the Audio stream in BIG event x is sent, it switches to send the Audio stream in BIG event x+1, in the above manner. 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.

Wherein one BIG event may comprise a plurality of SUB-BIG events. Each SUB-BIG event may comprise a BIS event, each for carrying a broadcast audio stream.

The display device broadcasts the first target Audio by using the bluetooth device, which may be implemented by an Audio service Audio Server service layer in an Audio service framework in the display device.

Fig. 8 is a schematic structural diagram of an Audio Server service layer according to an embodiment of the present application, where, as shown in fig. 8, the method includes: audio policy enforcement programs Audio player and Audio broadcasting programs (Audio hardware abstraction layer, audio HAL). Wherein Audio Flinger is used for changing the Audio channel of the display device. The Audio HAL is used for transmitting Audio data (Audio stream) corresponding to the Audio track to be broadcast to the Audio channel of the bluetooth device.

After the Audio Flinger in the Audio Server service layer obtains the Audio track in the first target Audio through the Audio service frame, the Audio channel of the display device is set to be a Bluetooth channel, audio data corresponding to the Audio track is sent to an Audio broadcast program Audio HAL, and the Audio HAL can send the Audio data corresponding to the Audio track to a broadcast Audio HAL of a Bluetooth device through the Audio service frame after receiving the Audio data corresponding to the Audio track.

After receiving the Audio data corresponding to the Audio track, the broadcast Audio HAL of the bluetooth device can forward the Audio data corresponding to the Audio track to a protocol stack of the bluetooth device, and the protocol stack encodes the received Audio data corresponding to the Audio track by a low-complexity communication codec (Low Complexity Communication Codec, LC 3) and then sends the encoded Audio data to a hardware control part of the bluetooth device. The hardware control part of the bluetooth device broadcasts the Audio data corresponding to the Audio track, i.e. broadcasts the Audio track, according to the LE Audio protocol.

S602, broadcasting mute data on an audio broadcasting channel through the Bluetooth device when the condition for triggering mute broadcasting is met.

In the embodiment of the application, when the display device broadcasts the first target audio, mute broadcasting may be required for some reasons, for example, a user performs a pause broadcasting program, or when the broadcast audio source is switched, in order to maintain the connection of the current broadcast channel, the overhead of additional resources brought by reestablishing the broadcast channel when the broadcast channel is disconnected or the broadcast channel is destroyed to cause subsequent recovery or continuing to perform audio broadcasting is reduced, and complicated operation is performed, so that the display device can maintain the connection of the current broadcast channel through mute broadcasting. So that when the audio broadcasting is resumed or continued, the audio broadcasting can be rapidly performed, thereby improving the user experience.

In one possible implementation, meeting the condition that triggers a silent broadcast may include pausing audio currently being broadcast.

Illustratively, receiving a pause broadcast control instruction of the first target audio; and determining that the condition for triggering mute broadcasting is met according to the pause broadcasting control instruction.

In some embodiments, the pause broadcast control instruction may be an instruction received by the display device from a user via the control device.

For example, as shown in fig. 9a, when the display device triggers the display device to display the audio track menu interface through the control device when the first target audio is broadcast, the display device may display the audio track menu interface 901, where the audio track menu interface 901 includes an audio track included in the currently broadcast first target audio and a "pause broadcast" control.

If the display device receives a trigger instruction of the user to the "pause broadcast" control in the audio track menu 901 through the control device, the display device may determine that the pause broadcast control instruction of the first target audio is received, so as to determine that a condition for triggering mute broadcast is satisfied.

It should be appreciated that upon receiving a trigger instruction to the "pause broadcast" control, the display device may pause broadcasting all of the tracks included in the first target audio. The "pause broadcast" control may also be named as another form of control, such as a cancel broadcast "control, which is not limited by the embodiments of the present application.

Optionally, in some embodiments, when the display device receives a trigger instruction for "pause broadcast" control, an interface as shown in fig. 9b may be displayed, where all the tracks being broadcast are displayed in the track selection interface 902, a check box is disposed in front of each track, and the display device may respond to a user's check instruction for one or more check boxes through the control device, and mark, as a checked state, a track corresponding to the check box. The track in the selected state is the track selected by the user to be paused.

If the display device receives a trigger instruction of the user to the "confirm" control in the track selection interface 902 through the control device, the display device uses at least one track selected by the user as a track needing to pause broadcasting.

When the display device determines to receive the pause broadcast control instruction of the first target audio, the first target audio can be processed to obtain mute data needing to be broadcast, and the mute data is broadcast, so that mute broadcast is realized.

Exemplary, extracting audio data corresponding to an audio broadcasting channel in the first target audio, and setting the audio data as a preset value to obtain mute data; mute data is broadcast over an audio broadcast channel by the bluetooth device.

In the embodiment of the application, taking an example that the first target audio includes an audio track, when the display device determines that the mute condition is met, the display device can suspend sending audio stream data corresponding to the first target audio to the bluetooth protocol stack of the bluetooth device, extract audio data broadcast by the first target audio in an audio broadcast channel, and set the audio data as a preset value to obtain mute data. For example, the audio data is set to zero.

It should be understood that when the first target audio is broadcast, the display device sends, to the bluetooth protocol stack of the bluetooth device, audio stream data corresponding to the first target audio may be non-zero audio stream data, and when the non-zero audio stream data is set to a zero value, the corresponding mute data may be obtained.

Optionally, in some embodiments, mute data may also be stored in the display device, and when it is determined that the pause broadcast control instruction of the first target audio is received, sending of audio stream data corresponding to the first target audio to the bluetooth protocol stack of the bluetooth device may be paused, so as to obtain the mute data stored in the display device.

When the display equipment acquires mute data, the mute data can be broadcast on the audio broadcasting channel through the Bluetooth device. The specific implementation process is similar to the implementation manner of broadcasting the first target audio on the audio broadcasting channel through the bluetooth device, and will not be repeated here.

It should be understood that the mute data is also broadcast by sending the mute data in audio tracks to the protocol stack corresponding to the bluetooth device.

In one possible implementation, meeting the condition that triggers a silent broadcast may include switching the audio currently being broadcast.

For example, when a switch instruction to switch from the first target audio to the second target audio is received, or when the first target audio broadcasting is completed and the second target audio is the next audio to be broadcasted, it is determined that a condition for triggering mute broadcasting is satisfied.

In the process of broadcasting the first target audio, if the display equipment receives an audio switching instruction sent by a user through the control device, the broadcasted audio needs to be switched from the first target audio to the second target audio, and in the process of audio switching, the display equipment can determine that the condition for triggering mute broadcasting is met.

Or, the display device stores a broadcast list, the display device can broadcast according to a broadcast sequence preset in the broadcast list, when the first target audio broadcast is completed and needs to be switched to the second target audio broadcast, the display device can determine that the condition for triggering mute broadcast is met in the audio switching process.

When the display device determines to switch the first target audio to the second target audio, in order to maintain the current audio broadcasting channel to be established, corresponding processing may be performed according to the number of audio tracks included in the second target audio.

Illustratively, the number of tracks of the second target audio is acquired; if the number of the audio tracks of the second target audio is greater than or equal to the number of the audio tracks of the first target audio, broadcasting mute data on an audio broadcasting channel through the Bluetooth device until broadcasting of the second target audio is started; if the number of the audio tracks of the second target audio is smaller than that of the audio tracks of the first target audio, setting redundant audio tracks as virtual audio tracks; broadcasting mute data on an audio broadcasting channel corresponding to the reserved audio track through the Bluetooth device until broadcasting of the second target audio is started; and continuously broadcasting mute data on the audio broadcasting channel corresponding to the virtual audio track through the Bluetooth device until the second target audio broadcasting is completed.

In the embodiment of the present application, as shown in fig. 10, a display device may parse a second target audio to be broadcasted, obtain the number of audio tracks included in the second target audio, and determine whether the number of audio tracks included in the second target audio and the number of audio tracks included in the first target audio change.

If the number of the audio tracks of the second target audio is greater than or equal to the number of the audio tracks of the first target audio, audio data broadcast by the first target audio in an audio broadcast channel can be processed to obtain mute data. And broadcasting mute data on an audio broadcasting channel through the Bluetooth device until a flow of broadcasting the second target audio begins. The specific implementation manner of obtaining the mute data is similar to the implementation manner of obtaining the mute data when the broadcast is paused, and will not be repeated here.

If the number of tracks of the second target audio is smaller than the number of tracks of the first target audio, the display device may construct a corresponding number of virtual tracks according to the difference of the number of tracks. For example, if the number of tracks of the second target audio is 3, the number of tracks of the first target audio is 5, and the difference is 2, 2 virtual tracks can be constructed.

Wherein the display device may construct the virtual audio track via a multimedia processing module, for example via a media layer.

When the display device constructs the virtual audio track, the audio data of the first target audio broadcast in the audio broadcast channel can be acquired and processed to obtain mute data. And writing the mute data into the virtual audio track to obtain the virtual audio track comprising the mute data.

The display apparatus may broadcast the virtual track including the mute data on the audio broadcasting channel through the bluetooth device and broadcast the mute data in the remaining broadcasting channels when constructing the virtual track including the mute data.

The broadcasting of the virtual audio track may be continuously broadcasting from switching the first target audio until the second target audio broadcasting is completed, and the broadcasting of the mute data in the remaining audio broadcasting channels may be continuously broadcasting from switching the first target audio until the second target audio broadcasting is started.

For example, the number of tracks of the second target audio is 3, the number of tracks of the first target audio is 5, and the display device may construct 2 virtual tracks. The display device may reserve 3 audio tracks, place the audio data of the reserved 3 audio tracks as mute data, and broadcast in the corresponding broadcast channel. And respectively writing the mute data into 2 virtual audio tracks, and broadcasting in the rest broadcasting channels.

According to the audio broadcasting method provided by the embodiment of the application, the Bluetooth device broadcasts the first target audio on the audio broadcasting channel; and broadcasting mute data on an audio broadcasting channel through the Bluetooth device when the condition of triggering mute broadcasting is met. When the display device performs Audio broadcasting based on the LE Audio protocol, the mute broadcasting sample is realized under the scenes of needing to pause the current broadcasting Audio, switching the current broadcasting Audio and the like, and the scene of using the LE Audio protocol of the display device is enlarged.

Alternatively, on the basis of the above embodiment, the display device may also stop broadcasting during the process of broadcasting the first target audio.

Illustratively, receiving a stop broadcast control instruction of the first target audio; stopping broadcasting the first target audio on an audio broadcasting channel through the Bluetooth device, and releasing resources for broadcasting the first target audio.

The implementation manner of receiving the broadcast stopping control instruction by the display device is similar to the implementation manner of receiving the broadcast stopping control instruction by the display device, and is not repeated here.

When the display device receives the broadcasting stopping control instruction, the sending of the audio stream data corresponding to the first target audio to the bluetooth protocol stack of the bluetooth device can be stopped, and a connection channel which is established with the protocol stack and used for sending the broadcasting audio stream data is disconnected, so that the bluetooth device releases resources occupied by broadcasting the first target audio, such as computing resources and the like. That is, the established audio broadcasting channel (audio track) is destroyed.

Optionally, on the basis of the foregoing embodiment, when broadcasting the first target audio, the method further includes switching the broadcasting channel to other playing channels of the display device, for example, a local loudspeaker of the display device.

The procedure of switching the broadcast channel to the other play channel of the display device will be described with reference to fig. 11.

Fig. 11 is a second flowchart of an audio broadcasting method according to an embodiment of the present application, as shown in fig. 11, including the following steps:

s1101, receiving a switching instruction of a broadcast channel of the first target audio; the switching instruction is used for indicating to switch from an audio broadcasting channel to a playing channel of the audio playing device.

In the embodiment of the application, the display device further comprises a built-in audio playing device, and/or the display device is externally connected with at least one audio playing device.

The audio playing device built in the display device may be a local speaker of the display device, and the display device is externally connected with at least one audio playing device and may be a sound box connected to the display device and used for playing audio.

The implementation manner of the display device receiving the switching instruction of the broadcast channel of the first target audio is similar to the implementation manner of the display device receiving the pause broadcast control instruction, and will not be described herein.

In a possible implementation manner, if the display device determines that the display device includes both the built-in audio playing device and the external at least one audio playing device according to the preset information, the display device may further display a switching selection prompt when receiving a switching instruction of the broadcast channel of the first target audio, so that a user may select to switch the audio broadcast channel to the playing channel of the built-in audio playing device and/or the playing channel of the external at least one audio playing device.

In a possible implementation manner, when the display device receives the switching instruction of the broadcast channel of the first target audio, the bluetooth type and/or the unique identifier of other devices externally connected to the display device may also be obtained, and it is determined whether the display device is externally connected to at least one audio playing device, if so, the switching selection prompt is displayed.

The display device may compare the bluetooth type and/or the unique identifier of the external other device with the bluetooth type and/or the unique identifier in the preset whitelist, and determine that the display device is externally connected with at least one audio playing device if the bluetooth type and/or the unique identifier in the preset whitelist exists.

S1102, stopping broadcasting the first target audio on the audio broadcasting channel through the Bluetooth device, and releasing the resources of the audio broadcasting channel.

In the embodiment of the present application, the specific implementation manner of S1102 is similar to the specific implementation manner when the broadcast stopping control instruction of the first target audio is received in the above embodiment, and will not be repeated here.

In some embodiments, the execution sequence of switching from the audio broadcasting channel to the playing channel of the audio playing device in the step S1101 may be executed before or after the first target audio is broadcast on the audio broadcasting channel by the bluetooth device in the step S1102, or may be executed simultaneously. The embodiment of the application does not limit the sequence of switching the broadcasting channel and stopping broadcasting the first target audio.

And S1103, playing the first target audio on an audio playing channel corresponding to the audio playing device.

In the embodiment of the application, when the display device determines the audio playing device to be switched, a connection channel with the audio playing device can be established. And sending the first target audio to the audio playing device through the connecting channel, and controlling the audio playing device to play the first target audio.

In some embodiments, when the first target audio is played on the audio playing channel corresponding to the audio playing device, the display device may further determine a type of audio to be played according to whether the first target audio is multi-track audio.

Illustratively, determining whether the first target audio is multi-track audio; if yes, acquiring a default language of the display equipment; and playing the audio track corresponding to the default language in the first target audio through the audio playing device.

As shown in fig. 12, if the display device determines that the first target audio is multi-track audio according to the number of audio tracks currently broadcast, a default language of the current display device may be obtained, and audio corresponding to an audio track in the first target audio corresponding to the default language is used as audio played by the audio playing device. When the audio played by the audio playing device is determined, the display device can discard the rest of the audio tracks in the first target audio, and only the audio tracks corresponding to the default language are reserved.

And if the display equipment determines that the first target audio is single-track audio, taking the first target audio as the audio played by the audio playing device.

For example, if the first target audio is multi-track audio including chinese, english and japanese and the default language of the display device is chinese, the chinese track included in the first target audio may be used as the audio played by the audio playing device.

In some embodiments, if the audio playing device is an audio playing device built in the display apparatus, the display apparatus may directly establish a connection channel with the built-in audio playing device, and send the audio to be played through the connection channel. The connection channel between the first test device and the built-in audio playing device can be established by referring to the implementation manner in the prior art, and will not be described herein.

If the audio playing device is an audio playing device externally connected with the display equipment, the display equipment establishes a corresponding playing channel according to a connection mode between the externally connected audio playing devices.

The connection mode of the external at least one audio playing device and the display device is obtained by way of an example; the connection mode comprises low-power-consumption LE connection and/or common connection; and constructing a playing channel for playing the first target audio according to the connection mode.

The normal connection may also be called a Basic Rate/enhanced data (BR/EDR) connection, a classical bluetooth connection, etc., which generally refers to a connection mode in which a connection protocol is below a bluetooth 4.0 protocol, and the Low Energy (LE) connection generally refers to a connection mode in which a connection protocol is above a bluetooth 4.0 protocol.

The display equipment can acquire configuration information of the connected audio playing devices, and the connection mode of the external at least one audio playing device and the display equipment is LE connection and/or common connection.

For example, if the display device is commonly connected to the external audio playing device, the display device may construct a common bluetooth audio transmission channel between the display device and the external audio playing device to play the first target audio. If the display device is connected with the external playing device through the LE, the display device can construct a low-power transmission channel between the display device and the external playing device to play the first target audio.

In some embodiments, as shown in fig. 13, when the display device determines a connection manner with an external audio playing device, constructing different playing channels according to the connection manner may include the following possible implementations:

In one possible implementation manner, if the connection manner is a normal connection, judging whether the external at least one audio playing device supports a bluetooth audio transmission model protocol A2DP; if the A2DP is supported, a common Bluetooth audio transmission channel between the display equipment and the external at least one audio playing device is constructed, and the external at least one audio playing device is controlled to play the first target audio through the common Bluetooth audio transmission channel; and if the A2DP is not supported, playing the first target audio through a built-in audio playing device.

The bluetooth audio transmission model protocol (Advanced Audio Distribution Profile, A2 DP), which may also be referred to as a media audio protocol, characterizes that an external audio playback device supports playing audio if the audio playback device supports A2 DP.

When the display equipment determines that the connection mode is the common connection, the display equipment can acquire the identification information of the external audio playing device, determine whether the audio playing device supports A2DP according to the identification information, and if so, the display equipment can establish a common Bluetooth audio transmission channel with the audio playing device.

When the common Bluetooth audio transmission channel is established, the display equipment can send the first target audio to the audio playing device through the common Bluetooth audio transmission channel so that the audio playing device plays the first target audio.

If the audio playing device does not support the A2DP, the display device can change the switched channel from the external ear audio playing device to the built-in audio playing device. And playing the first target audio through a built-in audio playing device.

Optionally, if the switched playing channel selected by the user is an audio playing device externally connected to the display device, the display device may display a corresponding prompt message when determining that the externally connected audio playing device does not support A2DP, so that the user reselects the switched playing channel.

In one possible implementation manner, if the connection manner is LE connection, a low-power transmission channel between the display device and the external at least one audio playing device is constructed, and the external at least one audio playing device is controlled to play the first target audio through the low-power transmission channel.

When the display device determines that the connection mode is LE connection, the display device can establish a low-power transmission channel with the audio playing device. When the low-power transmission channel is established, the display device can send the first target audio to the audio playing device through the low-power transmission channel so that the audio playing device plays the first target audio.

By way of example, the display device may send a request to the audio playback apparatus to establish an LE connection,

in one possible implementation manner, if the display device is externally connected with at least two audio playing devices, and the connection manner includes a common connection and an LE connection, a low-power transmission channel between the display device and the audio playing devices, and a common bluetooth audio transmission channel are sequentially constructed, and the low-power transmission channel and the common bluetooth audio transmission channel control the at least two audio playing devices to play the corresponding first target audio.

When the display device is externally connected with at least two audio playing devices, the connection mode of the display device and the audio playing devices may simultaneously comprise common connection and LE connection, so that the display device can firstly construct a low-power-consumption transmission channel between the display device and the audio playing devices, and then construct a common Bluetooth audio transmission channel between the display device and the audio playing devices.

The display device may send the first target audio to the corresponding audio playing device through the low-power transmission channel and the common bluetooth audio transmission channel, so that the audio playing device plays the first target audio.

In one possible implementation manner, if the connection manner includes both LE connection and normal connection, a low-power transmission channel between the display device and the external at least one audio playing device is constructed, and the external at least one audio playing device is controlled to play the first target audio through the low-power transmission channel.

The display device determines that a certain external audio playing device is connected with the display device through the LE connection and the common connection at the same time. The display device may preferentially construct a low-power transmission channel between the display device and the audio playing apparatus, and send the first target audio to the audio playing apparatus through the low-power transmission channel, so that the audio playing apparatus plays the first target audio.

It should be appreciated that when playing the first target audio through the external audio playing device, the display apparatus may determine the type of audio to be played according to whether the first target audio is multi-track audio. The specific implementation manner is similar to that in the above embodiment, and will not be repeated here.

The process of stopping broadcasting, suspending broadcasting and switching broadcasting channels under different scenarios provided by the embodiment of the present application is described above, and the operation process of the Audio Server in the above process will be briefly described below with reference to fig. 14.

For example, as shown in fig. 14, when the Audio Flinger obtains that the condition for triggering the mute broadcast is satisfied, the corresponding mute data is obtained, and the mute data is generated to a protocol stack of the bluetooth device, and the protocol stack performs LC3 encoding on the received mute data and then sends the encoded mute data to a hardware control part of the bluetooth device. The hardware control part of the Bluetooth device broadcasts the mute data according to the LE Audio protocol.

When the Audio Flinger obtains the instruction of stopping broadcasting or switching broadcasting channels, an instruction is sent to a protocol stack of the Bluetooth device through a common attribute protocol (generic attribute profile, GATT) so that the protocol stack of the Bluetooth device stops receiving the broadcasting Audio data, stops sending the broadcasting Audio data to the Audio HAL, and destroys the created Audio Track. If the received instruction is an instruction for switching broadcast channels, the Audio player can also create a new Audio channel Audio Track according to the play channel to be switched in the corresponding instruction.

The embodiment of the application also provides an audio broadcasting device.
