[0076] In order to enable a more clear understanding of the above-mentioned purposes, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0077] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other manners different from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present disclosure, and not all the embodiments.

[0078] The display device and the audio receiving device provided by the present disclosure can support Bluetooth-based low-power audio (LE Audio) technology, wherein the display device is an audio playing device or a device for configuring the audio receiving device. For example, the display device can be a television, a mobile phone, a projector, etc., and the audio receiving device can be a Bluetooth speaker, a Bluetooth earphone, etc.

[0079] Compared with classic Bluetooth, LE Audio has the following advantages:

[0080] 1. One audio playing device can simultaneously connect multiple audio receiving devices;

[0081] 2. One broadcast audio device can send broadcast audio to an unlimited number of audio receiving devices, supporting encrypted broadcast;

[0082] 3. The latest low complexity communication codec (LC3) audio format is adopted, and the sound quality is improved;

[0083] 4. Network telephony and high-definition calls are supported;

[0084] 5. Hearing aid / assistant hearing applications are supported.

[0085] The application layer specification telephone and media audio profile (TMAP) of LE Audio defines two kinds of media audio applications: unicast media audio and broadcast media audio.

[0086] Unicast media audio

[0087] The unicast media audio in TMAP employs more advanced audio codec to provide better sound quality and richer control function than the current classic Bluetooth media audio application specification (Advanced Audio Distribution Profile, A2DP) and media play control specification (Audio / Video Remote Control Profile, AVRCP). TMAP defines two roles for unicast media audio application: unicast media sender (UMS) and unicast media receiver (UMR). The UMS and UMR implement unicast media audio transmission through connection isochronous stream (CIS).

[0088] It should be noted that the unicast media audio defined in TMAP is not limited to one-to-one audio transmission, but also supports one-to-two unicast media audio transmission.

[0089] Figure 1 Fig. 1 is a schematic diagram of one-to-one unicast media audio transmission in the related art. As shown in Fig. 1, the UMS 11 transmits unicast media audio to the UMR 12. Figure 1

[0090] Figure 2 Fig. 2 is a schematic diagram of one-to-two unicast media audio transmission provided in the related art. As shown in Fig. 2, the UMS 21 transmits unicast media audio to the UMR 22 and the UMR 23, respectively. Figure 2

[0091] Broadcast media audio

[0092] The broadcast media audio in TMAP is based on connectionless multiple broadcast isochronous stream (BIS) synchronous transmission. The biggest advantage of the broadcast media audio is that audio data can be transmitted synchronously to multiple audio receiving devices.

[0093] The broadcast synchronization channel of the broadcast media audio in TMAP has two concepts of broadcast isochronous group (BIG) and BIS. One audio transmitting device can transmit multiple BIGs simultaneously, each BIG can be composed of multiple BISs, one BIG can contain up to 31 BISs, each BIS has a unique access address, and the access address of the BIS is generated based on the seed access address of the BIG to which it belongs according to a uniform algorithm.

[0094] ​​The broadcast media audio can include a plurality of advertisements with different access addresses, and exemplary advertisements can include:

[0095] Extended Advertising: Extended advertising on the primary advertising channel, using ADV_EXT_IND packet, and pointing to the secondary advertising by time and frequency information. The access address uses the primary advertising access address defined in the Bluetooth Core Specification: 0x8E89BED6.

[0096] Periodic Advertising: The secondary advertising uses AUX_ADV_IND packet, and points to the periodic advertising by time, frequency hopping map and access address. The periodic advertising uses AUX_SYNC_IND packet, and the periodic advertising contains BIG information (BIGInfo).

[0097] Broadcast Isochronous Stream (BIS): BIS pointed to by time, frequency hopping map, access address and BIG information (BIGInfo) in the periodic advertising, using BIS PDU packet, and broadcasting digital audio in the BIS.

[0098] Figure 3 The relationship between the extended advertising, the periodic advertising and the BIS is shown in the diagram. It should be noted that the Bluetooth works in the 2.4 GHz frequency band, and the frequency range of the 2.4 GHz frequency band is between 2402 MHz and 2480 MHz, with 40 channels, each 2 MHz, of which 3 are primary advertising channels, namely channel 37, channel 38 and channel 39, and the remaining 37 channels are secondary advertising channels, which are channel 0 to channel 36. Figure 3 As shown, the primary advertising channel includes channel 37, channel 38 and channel 39; the secondary advertising channel includes channel 0 to channel 36. The extended advertising on the primary advertising channel can use ADV_EXT_IND packet, and point to the secondary advertising of the secondary advertising channel by time and frequency information, and then the secondary advertising uses AUX_ADV_IND packet, and points to the periodic advertising by time, frequency hopping map and access address. Further, the periodic advertising uses AUX_SYNC_IND packet, and points to the BIS by time, frequency hopping map, access address and BIG information (BIGInfo), and the BIS uses BIS PDU packet, and broadcasts digital audio.

[0099] Figure 4 The relationship between the extended advertising packet, the secondary advertising packet, the periodic advertising packet and the BIS is shown in the diagram. Figure 4As shown, the audio transmitting device transmits an extended broadcast packet (ADV EXT IND) on a main broadcast channel (37, 38, 39), which includes a broadcast device address (AdvA), broadcast data information (ADI), and a pointer of an auxiliary broadcast packet (AuxiliaryPointer, AuxPtr). The AuxPtr indicates that an auxiliary broadcast is performed on a sub broadcast channel next, and the auxiliary broadcast packet (AUX ADV IND) includes extended broadcast data (AdvData), a broadcast audio announcement service universal unique identifier (BroadcastAudio Announcement Service UUID), other service universal unique identifiers (Others Service UUIDs), and data indicating a periodically broadcasted data channel and a broadcast period. The periodically broadcast packet (AUX SYNC IND) includes additional broadcast data BIG information (Additional Controller Advertising Data BIG info, ACAD BIG info), and extended broadcast data basic audio announcement service universal unique identifier (AdvData BasicAudio Announcement Service UUID), BASE. The periodically broadcast packet contains all information of a broadcast isochronous stream BIS. After receiving the periodically broadcast packet, a broadcast receiver receives BIS data at a specific channel and a specific time anchor according to the data included in the periodically broadcast packet, and obtains a BIS audio stream.

[0100] In actual applications, when broadcasting digital audio in the BIS mode, BIGs are continuously transmitted. Each transmission of a BIG can be referred to as a BIG event, and each BIG event can include multiple BISs.

[0101] Figure 5 FIG. 1 is a schematic diagram of a continuous transmission of BIGs in the related art. As shown, in the process of continuously transmitting BIGs, BIG events are periodically and continuously performed, Figure 5 Figure 6 The BIG anchors shown in FIG. 2 indicate the start time of each BIG event, and the time interval between two anchors is a period of performing a BIG event. It should be noted that Figure 5 FIG. 2 is an example of three BIG events, each of which includes two BISs, Figure 5 FIG. 3 shows the continuous performance of BIG event X, BIG event (X+1), and BIG event (X+2), each of which includes two BIS streams, which are Figure 5 ​The diagram shows BIS1 and BIS2. During the execution of the BIG time, a BIS stream is broadcast, and during the broadcast of the BIS stream, the BIS stream is broadcast once at fixed time intervals.

[0102] The volume adjustment method for a display device provided in this disclosure can be implemented using a display device and an audio receiving device. The display device can be a television, computer, etc., and the audio receiving device can be a speaker, headphones, etc. Alternatively, the volume adjustment method for a control terminal provided in this disclosure can be implemented using a control terminal and a display device. The control terminal can be a mobile terminal, such as a mobile phone, tablet computer, wearable device, etc., which can be used to implement functions such as adjusting the volume of the audio receiving device. Wearable devices can be smartwatches, smart bracelets, etc.

[0142] For example, when implementing the volume adjustment method provided by the embodiments of the present application, the operations performed by the control terminal 300 can be implemented by the controller 380.

[0143] In some embodiments, the controller 380 is configured to: control the Bluetooth module to establish a communication connection with a target display device; receive device information and initial volume information of a target audio receiving device based on the communication connection; wherein the target audio receiving device has a Bluetooth connection with the target display device; receive a volume adjustment operation for the target audio receiving device based on the device information and the initial volume information of the target audio receiving device, to obtain adjusted volume information of the target audio receiving device; and send the adjusted volume information of the target audio receiving device to the target display device based on the communication connection; wherein the target display device is configured to send the adjusted volume information to the target audio receiving device, and the target audio receiving device is configured to adjust its own volume by using the adjusted volume information.

[0146] Corresponding to the scene diagram as shown in Figure 6 , the embodiment of the present disclosure provides a volume adjustment method as shown in Figure 11 , which is applied to a display device. As shown in Figure 11 , the flowchart of the volume adjustment method provided by the embodiment of the present disclosure is shown in Figure 1 . As shown in Figure 11 , the method can include but is not limited to the following steps S1102-S1108:

[0147] S1102, control the Bluetooth module to establish a communication connection with a target control terminal.

[0148] In the embodiment of the present disclosure, the display device can be built-in with a Bluetooth module supporting the low-energy Bluetooth audio protocol (LEaudio), and the Bluetooth module is used to establish a communication connection with a target control terminal. The target control terminal can be any smart device supporting the LEaudio protocol, such as a mobile phone, a tablet computer, a wearable device, etc., wherein the wearable device can be a smart watch, a smart bracelet, etc.

[0149] In actual application, before the display device controls the Bluetooth module to establish a communication connection with the target control terminal, the display device can also discover audio receiving devices around through a Bluetooth scanning function, and display the scanned audio receiving devices on a device management page. The scanned audio receiving devices can include devices supporting Bluetooth function, such as earphones, sound boxes, etc. During the process of displaying the scanned audio receiving devices on the device management page, the display device can also receive a pairing operation of a user for any audio receiving device, and establish a Bluetooth connection with the audio receiving device.

[0150] In practical applications, when a display device plays music or video, in order to achieve better sound playback effects, the display device usually establishes an Access Control List (ACL) connection and a Volume Control Profile (VCP) connection with the audio receiving device. Audio information is sent to the audio receiving device through the VCP connection, and the audio receiving device plays the sound after receiving the audio information.

[0151] like Figure 12 The diagram shown is a schematic representation of a device management page provided in an embodiment of this disclosure. Figure 12 The page displays device identifiers for the audio receiving devices scanned by the display device, namely "Bluetooth Speaker 3" and "Bluetooth Speaker 4". Bluetooth Speaker 3 and Bluetooth Speaker 4 are Bluetooth devices scanned by the display device through its Bluetooth module. Furthermore, after receiving a selection command for the device identifier "Bluetooth Speaker 3", the display device can establish a Bluetooth connection with the audio receiving device indicated by "Bluetooth Speaker 3".

[0152] In some embodiments, the display device can establish a communication connection with the target control terminal via Bluetooth broadcast. Specifically, upon receiving a display trigger operation for the volume configuration page, the display device controls the Bluetooth module to enter broadcast mode to enable its Bluetooth broadcast function; then, it controls the Bluetooth module to send a first broadcast packet; and upon receiving a communication connection establishment request, it controls the Bluetooth module to establish a communication connection with the target control terminal that sent the request.

[0153] In this embodiment of the disclosure, the first broadcast packet carries device information of the display device, such as the name information, MAC address information, serial number information, etc. of the display device. The device information can be used to trigger the establishment of a communication connection with the display device corresponding to the device information.

[0154] In some embodiments, when the display device receives a display trigger operation for the volume configuration page, it can also switch the current audio output channel to the Bluetooth broadcast channel, and then send Bluetooth broadcast packets outward based on the Bluetooth broadcast channel.

[0155] In practical applications, users can adjust the volume of the target audio receiving device through the target control terminal before the display device plays audio or video files, or they can adjust the volume of the target audio receiving device through the target control terminal while the display device is playing audio or video files. These two volume adjustment scenarios will be described in detail in subsequent embodiments and will not be elaborated here.

[0156] In some embodiments, the display triggering operation for the volume configuration page can include triggering operations for the "adjust volume through mobile phone" control on the management page before playing the audio / video file, triggering operations for the "adjust volume through mobile phone" control on the audio / video playing page during playing the audio / video file, and the like. The display triggering operation for the audio configuration page is not limited in the embodiments of the present disclosure.

[0157] In some embodiments, since the display device and the target control terminal both support the LEaudio protocol, the display device can control the Bluetooth module to establish a GATT connection with the target control terminal. GATT is a Bluetooth protocol profile for establishing a communication connection between Bluetooth low-power devices. In actual applications, the GATT connection can be used to realize data transmission and interaction between the television and the mobile phone.

[0158] The embodiments of the present disclosure do not limit the execution order of the above steps. For example, the step of "controlling the Bluetooth module to establish a Bluetooth connection with the audio receiving device" can be executed first, and then the step of "controlling the Bluetooth module to establish a communication connection with the target control terminal" can be executed. One or more steps can be added before the above steps, such as the steps of "controlling the Bluetooth module to scan the surrounding audio receiving devices" and "displaying the scanned audio receiving devices on the device management page" before the step of "controlling the Bluetooth module to establish a Bluetooth connection with the audio receiving device".

[0159] S1104, based on the communication connection, sending device information and initial volume information of the target audio receiving device to the target control terminal.

[0160] The target audio receiving device has a Bluetooth connection with the display device, and the target control terminal is configured to obtain adjusted volume information of the target audio receiving device based on the device information and the initial volume information.

[0161] In the embodiments of the present disclosure, after the display device controls the Bluetooth module to establish a communication connection with the target control terminal, the display device can also send device information and initial volume information of the target audio receiving device to the target control terminal based on the communication connection. The target audio receiving device can be any one or more audio receiving devices that have a Bluetooth connection with the display device.

[0162] In some embodiments, the display device can further acquire the device information and the initial volume information of the target audio receiving device before sending the device information and the initial volume information of the target audio receiving device to the target control terminal based on the communication connection. Further, when receiving the selection instruction for "adjusting the volume through the mobile phone", the display device can first control the Bluetooth module to enter the broadcast state, then control the Bluetooth module to send a first broadcast packet carrying the device information of the display device, and when receiving a communication connection establishment request, control the Bluetooth module to establish a communication connection with the target control terminal sending the communication connection establishment request, and then send the device information and the initial volume information of the target audio receiving device to the target control terminal based on the communication connection, so that the target control terminal acquires the adjusted volume information of the target audio receiving device based on the device information and the initial volume information.

[0163] In some embodiments, the display device can further send the device information and the initial volume information of the target audio receiving device to the target control terminal based on the communication connection, and send a debugging audio file corresponding to the initial volume information. The debugging audio file refers to a test sound file before adjusting the volume of the audio receiving device, and the debugging audio file can help the user to adjust the volume of the audio receiving device to obtain a better sound playing effect.

[0164] In actual application, after receiving the device information, the initial volume information and the debugging audio file corresponding to the initial volume information of the target audio receiving device, the target control terminal can help the user to adjust the volume of the audio receiving device based on the target control terminal by playing the debugging audio file on the volume adjustment interface of the target control terminal. The debugging audio file can include volume range debugging and channel debugging information, for example, different volume sizes of sound can be played based on the volume debugging information in the debugging audio file to help the user to adjust the volume range of the audio receiving device based on the target control terminal.

[0165] In some embodiments, the device information, the initial volume information and the debugging audio file of the target audio receiving device can also be sent to the target control terminal in the form of a data packet. Specifically, the device information, the initial volume information and the debugging audio file of the target audio receiving device can be encapsulated in an audio data packet and sent to the target control terminal in the form of a data packet.

[0166] The execution sequence of the above steps is not limited in the embodiments of the present disclosure. For example, the step of "receiving a selection operation for a target audio receiving device in a device management page, and obtaining device information and initial volume information of the target audio receiving device" can be executed first, and then the step of "sending the device information and the initial volume information of the target audio receiving device to the target control terminal based on the communication connection" can be executed. One or more steps can be added before the above steps. For example, before the step of "sending the device information and the initial volume information of the target audio receiving device to the target control terminal based on the communication connection", a step of "packaging the device information and the initial volume information of the target audio receiving device in an audio data packet" can be added.

[0167] S1106, receiving the adjusted volume information of the target audio receiving device from the target control terminal based on the communication connection.

[0168] In actual application, after receiving the device information and the initial volume information of the target audio receiving device, the target control terminal can further obtain the adjusted volume information of the target audio receiving device based on the device information and the initial volume information, and send the adjusted volume information to the display device. The display device receives the adjusted volume information of the target audio receiving device from the target control terminal based on the communication connection.

[0169] In some embodiments, after the display device receives the adjusted volume information of the target audio receiving device from the target control terminal based on the communication connection, the display device can further determine whether the target audio receiving device corresponding to the adjusted volume information belongs to devices in the target network group; if it is determined that the target audio receiving device is a device in the target network group, the display device triggers the step of sending the adjusted volume information to the target audio receiving device based on the Bluetooth connection.

[0170] In actual application, devices connected to the same local area network through a network are usually determined as devices in the same network group, or devices using a specific network protocol for communication are determined as devices in the same network group. Multiple devices in the same network group can implement a multi-room audio synchronization function, i.e., devices placed in different rooms can play the same music or sound synchronously.

[0171] In some embodiments, when the display device determines that the target audio receiving device is a device in the target network group, the display device can further control the display to display each audio receiving device in the target network group, and send the adjusted volume information to each audio receiving device in the target network group based on the Bluetooth connection, so as to adjust the volume of the audio receiving devices in the same network group.

[0172] In some embodiments, after receiving the adjusted volume information of the target audio receiving device from the target control terminal based on the communication connection, the display device can further control the display to display the adjusted volume information of the target audio receiving device, so that the user can know the current volume of the target audio receiving device based on the display of the display device.

[0173] In some embodiments, in the process of controlling the display to display the adjusted volume information of the target audio receiving device, the display device can further receive a volume adjustment operation for the target audio receiving device to adjust the volume of the target audio receiving device again.

[0174] The execution order of the above steps is not limited in the embodiments of the present disclosure. For example, the step of "determining whether the target audio receiving device corresponding to the adjusted volume information belongs to the devices in the target network group" can be performed first, and then the step of "sending the adjusted volume information to the target audio receiving device based on the Bluetooth connection" is performed when it is determined that the target audio receiving device belongs to the devices in the target network group.

[0175] S1108, sending the adjusted volume information to the target audio receiving device based on the Bluetooth connection.

[0176] The target audio receiving device is configured to adjust its own volume by using the adjusted volume information.

[0177] In the embodiments of the present disclosure, the Bluetooth connection between the display device and the target audio receiving device can be used for data transmission and interaction. Therefore, after receiving the adjusted volume information of the target audio receiving device, the display device can send the adjusted volume information to the target audio receiving device based on the Bluetooth connection, so that the target audio receiving device adjusts its own volume by using the adjusted volume information.

[0178] In the volume adjustment method provided by the embodiments of the present disclosure, first, the Bluetooth module is controlled to establish a communication connection with a target control terminal, and based on the communication connection, device information and initial volume information of a target audio receiving device are sent to the target control terminal, so that the target control terminal obtains adjusted volume information based on the device information and the initial volume information. Then, based on the communication connection, the adjusted volume information of the target audio receiving device from the target control terminal is received. Further, based on the Bluetooth connection between the display device and the target audio receiving device, the adjusted volume information is sent to the target audio receiving device, so that the target audio receiving device adjusts its own volume by using the adjusted volume information. It can be seen that the display device in the embodiments of the present disclosure can transmit initial volume information to the control terminal and receive adjusted volume information from the control terminal based on the communication connection, so as to realize volume adjustment of the audio receiving device establishing a Bluetooth connection with the display device in the control terminal.

[0179] In practical applications, the audio channel information can also be reconfigured based on the communication connection between the display device and the target control terminal. Specifically, the display device first sends the audio channel information to be configured to the target control terminal based on the communication connection; the target control terminal then reconfigures the BIS identifier based on the audio channel information to be configured; next, it receives the reconfigured BIS identifier from the target control terminal based on the communication connection; further, based on the Bluetooth connection, it sends the reconfigured BIS identifier to the target audio receiving device, so that the target audio receiving device can obtain the target BIS audio from multiple BIS streams broadcast by the display device based on the reconfigured BIS identifier and play the target BIS audio. Additionally, the audio receiving device can also be paired / unpaired based on the communication connection between the display device and the target control terminal. The specific implementation process can be understood by referring to the above-described audio channel information reconfiguration process, and will not be elaborated here.

[0180] like Figure 13 The diagram shown is a schematic representation of a scenario where the volume is adjusted via a mobile phone before playing an audio or video file, according to an embodiment of this disclosure. Figure 13 (a) The display device's settings page shows a "Adjust volume via mobile phone" control. When the display device receives a selection command for the "Adjust volume via mobile phone" control, it controls the Bluetooth module to enter broadcast mode. Figure 13 As shown in (b), this is a schematic diagram of a Bluetooth broadcast switching process provided in an embodiment of the present disclosure. After the display device successfully switches to the Bluetooth broadcast channel, it sends out a first broadcast packet carrying device information of the display device.

[0181] When the target control terminal detects the first broadcast packet, it parses the packet to obtain the device information of the display device. Based on this device information, it sends a communication connection establishment request to the display device to request the establishment of a communication connection. Upon receiving the communication connection establishment request from the target control terminal, the display device controls the Bluetooth module to establish a communication connection with the target control terminal. After successfully establishing a communication connection with the target control terminal, the display device can also display a prompt message on the current page: "Please select a Bluetooth speaker with volume adjusted via your mobile phone after connecting to your mobile phone." Figure 13 (c) shows a selection page for an audio receiving device provided in an embodiment of this disclosure; the display shows the device receiving... Figure 13 (c) When a selection command is given for Bluetooth speaker 1, the device information and initial volume information of Bluetooth speaker 1 are sent to the target audio receiving device, so that the target control terminal can obtain the adjusted volume information of the target audio receiving device based on the aforementioned device information and initial volume information. Figure 13(d) as shown, the display device can also display the adjusted sound box information of the Bluetooth sound box 1 on the device management page when receiving the adjusted volume information of the Bluetooth sound box.

[0182] As shown in Figure 14 , a scene schematic diagram provided by the embodiment of the present disclosure for adjusting the volume through the mobile phone in the process of playing the audio and video file. Figure 14 (a) as shown, the audio and video file is being played on the audio and video playing page, and the display device controls the Bluetooth module to enter the broadcast state when receiving the selection instruction for the "adjust the volume through the mobile phone" control in the audio and video playing page. In actual application, in order to not affect the user's viewing experience of the audio and video file, only the adjusted sound box information of the target audio receiving device needs to be displayed on the audio and video playing page, as shown in Figure 14 (b) as shown, a display schematic diagram of the adjusted volume information of the target audio receiving device provided by the embodiment of the present disclosure.

[0183] Corresponding to the scene schematic diagram as shown in Figure 6 , the embodiment of the present disclosure also provides a volume adjustment method as shown below Figure 15 , which is applied to a control terminal. As shown in Figure 15 , a flow schematic diagram of the volume adjustment method provided by the embodiment of the present disclosure Figure 2 . As shown in Figure 15 , the method can include but is not limited to the following steps S1502-S1508:

[0184] S1502: control the Bluetooth module to establish a communication connection with the target display device.

[0185] In some embodiments, a broadcast assistant application program can be provided in the control terminal, which can be used to realize the functions of scanning the surrounding Bluetooth broadcast packets and adjusting the volume of the target audio receiving device, and the control terminal controls the Bluetooth module to enter the scanning state when receiving the starting operation of the broadcast assistant application program, and when the first broadcast packet of the target display device is scanned, the first broadcast packet is first analyzed to obtain the device information carried in the first broadcast packet; then a communication connection establishment request is sent to the target display device corresponding to the device information to establish a communication connection with the target display device.

[0186] In actual application, the target display device controls the Bluetooth module to establish a communication connection with the target control terminal sending the communication connection establishment request when receiving the communication connection establishment request.

[0187] As shown in Figure 16 , an interface schematic diagram for triggering the starting of the broadcast assistant application provided by the embodiment of the present disclosure. For example, as shown in Figure 16As shown in (a), the control terminal's display screen can show the application identifier of the broadcast assistant application. Upon receiving a user's selection command for the application identifier of the broadcast assistant application, the control terminal can activate the Bluetooth scanning function to scan for nearby Bluetooth broadcast packets. After activating the Bluetooth scanning function and detecting at least one Bluetooth broadcast packet, the control terminal can display the device information from at least one Bluetooth broadcast packet on the current page, allowing the user to select the display device from which to establish a communication connection based on the displayed device information. Figure 16 As shown in (b), the current page of the control terminal displays display devices that can establish communication connections, such as TV 1 and TV 2.

[0188] When the control terminal receives a selection operation for a target display device in at least one display device, it sends a communication connection establishment request to the target display device to establish a communication connection with the target display device.

[0189] The embodiments disclosed herein do not limit the execution order of the above steps. For example, one or more steps can be added before the above steps. For example, before the step "establish a communication connection with the target display device", steps such as "control the Bluetooth module to enter the scanning state and scan the first broadcast packet" and "send a communication connection establishment request to the target display device corresponding to the device information based on the device information carried in the first broadcast packet" can be added.

[0190] S1504: Based on the communication connection, receive the device information and initial volume information of the target audio receiving device.

[0191] The target audio receiving device and the target display device are connected via Bluetooth.

[0192] In this embodiment of the disclosure, after the control terminal establishes a communication connection with the target display device, it can receive device information and initial volume information from the target audio receiving device of the target display device based on the communication connection.

[0193] In practical applications, the target display device establishes Bluetooth connections such as ACL and VCP with the target audio receiving device and completes the channel information configuration before establishing a communication connection with the control terminal. Therefore, when the target display device receives a communication connection establishment request, it can directly send the device information and initial volume information of the target audio receiving device to the control terminal based on the communication connection.

[0194] In some embodiments, after receiving the device information and initial volume information of the target audio receiving device, the control terminal may also display the initial volume information of the target audio receiving device. For example... Figure 17Fig. 1 shows a schematic diagram of a volume adjustment interface of a control terminal according to an embodiment of the present disclosure. As shown, the interface displays device information and initial volume information of a target audio receiving device, for example, initial volume information of Bluetooth speaker 1. The control terminal receives a volume adjustment operation for the initial volume information of Bluetooth speaker 1, and obtains adjusted volume information of Bluetooth speaker 1.

[0195] S1506: Based on the device information and initial volume information of the target audio receiving device, the control terminal receives a volume adjustment operation for the target audio receiving device, and obtains adjusted volume information of the target audio receiving device.

[0197] In some embodiments, during the process of displaying the device information and initial volume information of the target audio receiving device on the volume adjustment interface, the control terminal can also receive a volume adjustment operation of the initial volume information by the user acting on the volume adjustment interface, and determine the adjusted volume as the adjusted volume information of the target audio receiving device.

[0198] In some embodiments, in response to the volume adjustment of the initial volume information acting on the volume adjustment interface, before determining the adjusted volume information of the target audio receiving device, the control terminal can also play a debugging audio file on the volume adjustment interface. The volume of the debugging audio file is determined based on the volume adjustment operation.

[0199] S1508: Based on the communication connection, the control terminal sends the adjusted volume information of the target audio receiving device to the target display device.

[0200] The target display device is configured to send the adjusted volume information to the target audio receiving device, and the target audio receiving device is configured to adjust its volume based on the adjusted volume information.

[0201] In the embodiment of the present disclosure, after the control terminal receives the volume adjustment operation for the target audio receiving device and obtains the adjusted volume information of the target audio receiving device, the control terminal can send the adjusted volume information of the target audio receiving device to the target display device based on the communication connection, so that the target display device sends the adjusted volume information to the target audio receiving device based on the Bluetooth connection, thereby realizing the volume adjustment function of the audio receiving device.

[0202] In some embodiments, the control terminal can also use audio data packets to send the adjusted volume information of the target audio receiving device to the target display device. Specifically, the adjusted volume information of the target audio receiving device is first encapsulated in the header of the audio data packet, and then the audio data packet is sent to the target display device based on the communication connection. After receiving the audio data packet, the target display device parses the audio data packet to obtain the adjusted volume information of the target audio receiving device.

[0203] In practical applications, the audio data packet can also include configured channel information. After receiving the audio data packet, the target display device can also send the corresponding BIS identifier to the connected audio receiving device based on the channel information, so that the audio receiving device can obtain the BIS stream corresponding to the BIS identifier based on the BIS identifier.

[0204] In the volume adjustment method provided in this embodiment, the control terminal first controls the Bluetooth module to establish a communication connection with the target display device; then, based on the communication connection, it receives the device information and initial volume information of the target audio receiving device, wherein the target display device and the target audio receiving device have a Bluetooth connection; next, based on the device information and initial volume information of the target audio receiving device, it receives a volume adjustment operation for the target audio receiving device to obtain the adjusted volume information of the target audio receiving device; further, based on the communication connection, it sends the adjusted volume information of the target audio receiving device to the target display device, so that the target display device sends the adjusted volume information to the target audio receiving device, thereby realizing the function of adjusting the volume of the audio receiving device that has established a Bluetooth connection with the display device from the control terminal.
