302. In response to a trigger operation for the target broadcast synchronization information, the second terminal performs broadcast synchronization with the first terminal broadcasting the target broadcast synchronization information.

In the embodiment of the application, in the case that the first terminal used by the passenger of the target vehicle broadcasts the broadcast synchronization information through bluetooth, the broadcast synchronization information of the at least one broadcast source device obtained by bluetooth scanning by the second terminal includes the broadcast synchronization information of the first terminal. In order to enable the second terminal to receive the multimedia data of the first terminal, the driver can select the broadcast synchronization information of the first terminal from the broadcast synchronization information of the at least one broadcast source apparatus displayed by the second terminal to enable the second terminal to access the broadcast of the first terminal. Accordingly, in response to a trigger operation for the target broadcast synchronization information, the second terminal can perform broadcast synchronization with the first terminal based on the target broadcast synchronization information.

Therefore, the second terminal can receive the operation instruction shared by the first terminal through the data transmission channel between the first terminal and the second terminal. Because the second terminal establishes a bluetooth connection with the vehicle terminal of the target vehicle, the second terminal can send the received operation instruction to the vehicle-mounted terminal through the bluetooth connection, and the vehicle-mounted terminal executes the operation instruction. The operation instruction may be a play instruction and a volume adjustment instruction for the specified multimedia data, or may be an operation instruction for any function in the vehicle-mounted terminal, such as turning on or off an air conditioner of the target vehicle, which is not limited in the embodiment of the present application.

401. In response to an on operation of the data sharing function, the first terminal broadcasts broadcast synchronization information of the first terminal through bluetooth, the broadcast synchronization information including at least one of a broadcast name, broadcast content, broadcast configuration, and transmission parameters of the first terminal.

In the embodiment of the present application, taking the terminal used by the first terminal as the passenger of the target vehicle as an example, the first terminal is installed with an application program having a data sharing function. Taking the second terminal as an example of a terminal used by a driver of the target vehicle, the second terminal establishes Bluetooth connection with a vehicle-mounted terminal of the target vehicle. In the driving process, a driver can screen the navigation, music, video and other contents displayed by the second terminal onto the vehicle-mounted terminal through Bluetooth connection between the second terminal and the vehicle-mounted terminal, so that better navigation experience and audio-visual experience are obtained. Under the condition that a driver plays multimedia data while using a vehicle-mounted terminal and a navigator, if a passenger does not like the currently played multimedia data and wants to replace the multimedia data played by the vehicle-mounted terminal, the passenger starts a data sharing function of the first terminal, so that the first terminal can share a playing instruction of the appointed multimedia data to the second terminal. Accordingly, in response to an operation of starting a data sharing function of the first terminal, the first terminal can start a bluetooth module in the first terminal and broadcast synchronization information of the first terminal through the bluetooth module, so that the second terminal can receive multimedia data shared by the first terminal based on the broadcast synchronization information. Wherein the broadcast synchronization information includes at least one of a broadcast name, broadcast content, broadcast configuration, and transmission parameters of the first terminal. The broadcast name is used to identify the first terminal, and may be a device model of the first terminal, or may be a device name set for the first terminal by a user of the first terminal. The broadcast content is used to reflect content broadcast by the first terminal via bluetooth. The broadcast configuration is used to reflect the parameter configuration of the first terminal broadcasting through bluetooth, such as a broadcast channel, a broadcast frequency, etc. when the first terminal broadcasts. The transmission parameter is used to indicate the parameter configuration, such as codec configuration, transmission rate, transmission delay, etc., used when the first terminal transmits the multimedia data. The codec configuration may be in a WMA (Windows Media Audio ) codec format or in an mp3 codec format.

402. And under the condition that the second terminal performs Bluetooth scanning, the second terminal displays the broadcast synchronous information of at least one broadcast source device obtained by scanning, and Bluetooth connection is established between the second terminal and the vehicle-mounted terminal.

In the embodiment of the application, the second terminal is used as a broadcast receiving end, and Bluetooth scanning can be performed through the Bluetooth module of the second terminal. In the process of Bluetooth scanning, the second terminal can acquire the broadcast synchronization information of at least one broadcast source device which broadcasts nearby, and display the broadcast synchronization information of the at least one broadcast source device on a screen of the second terminal for selection by a driver. Alternatively, the second terminal can display only the broadcast name of at least one broadcast source device on the screen so that the driver selects the first terminal from the plurality of broadcast source devices for access according to the broadcast name of the first terminal.

In some embodiments, the process of obtaining the broadcast synchronization information of any broadcast source device by the second terminal through bluetooth scanning includes: for any broadcast source device, the second terminal can acquire a broadcast data packet from a main broadcast channel of the broadcast source device for extension broadcast, wherein the broadcast data packet is used for pointing to an auxiliary broadcast channel of the extension broadcast; then, the second terminal acquires synchronization auxiliary information of the broadcast source equipment from the auxiliary broadcast channel based on the broadcast data packet, wherein the synchronization auxiliary information comprises the time, the frequency hopping map and the access address of the broadcast source equipment for periodical broadcasting; finally, the second terminal performs periodical broadcast synchronization with the broadcast source equipment based on the synchronization auxiliary information; in the case where the periodic broadcast synchronization is completed, the second terminal acquires broadcast synchronization information of the broadcast source device from the periodic broadcast. In the process of broadcasting the broadcast synchronization information, the broadcast source device performs extended broadcast. The second terminal can obtain a broadcast data packet on the main broadcast channel of the extended broadcast according to the main broadcast access address corresponding to the main broadcast channel specified in the bluetooth core specification, where the broadcast data packet may be a PDU (Protocol Data Unit ) including information that points to the auxiliary broadcast channel such as time, frequency, and the like of the auxiliary broadcast channel of the extended broadcast. Accordingly, the second terminal can further acquire synchronization auxiliary information including information directed to the periodic broadcast such as time, frequency hopping, and access address at which the broadcast source device performs the periodic broadcast from the subsidiary broadcast channel of the extended broadcast. The second terminal can perform PA (Periodic Advertising, periodic broadcast) synchronization with the first terminal based on the synchronization assistance information. And acquiring the broadcast synchronization information of the broadcast source device from the periodic broadcast under the condition that the PA synchronization is completed.

403. And responding to the triggering operation of the target broadcast synchronization information, wherein the second terminal performs broadcast synchronization with the first terminal, and the target broadcast information is the broadcast synchronization information of the first terminal in the broadcast synchronization information of the at least one broadcast source device.

In the embodiment of the present application, the target broadcast information is broadcast synchronization information of the first terminal in the broadcast synchronization information of at least one broadcast source device. Accordingly, in order to enable the second terminal to receive the multimedia data shared by the first terminal, the driver can select target broadcast synchronization information from the broadcast synchronization information of the at least one broadcast source apparatus. Accordingly, in response to a trigger operation for the target broadcast synchronization information, the second terminal can perform broadcast synchronization with the first terminal based on the target broadcast synchronization information, so that the second terminal accesses the broadcast of the first terminal. The broadcast synchronization is BIS (Broadcast Isochronous Stream, broadcast synchronization data stream) synchronization.

404. In the case that the broadcast synchronization is completed, the first terminal establishes a data transmission channel between the first terminal and the second terminal.

In the embodiment of the application, under the condition that the broadcast synchronization is completed, the first terminal is indicated to have received the response of the second terminal to the broadcast synchronization information of the first terminal, namely, the second terminal has successfully accessed the broadcast of the first terminal. Thus, the first terminal can establish a data transmission channel with the second terminal. The data transmission channel is used for transmitting any operation instruction triggered by a user in the first terminal.

In some embodiments, in the case that the broadcast synchronization is completed, the first terminal can display a prompt message prompting whether to allow the second terminal to access. Correspondingly, under the condition that a response of the second terminal to the broadcast synchronous information is received, the first terminal displays first prompt information, and the first prompt information is used for prompting whether the second terminal and the first terminal are allowed to establish broadcast connection or not; then, in response to a confirmation operation of the first prompt information, the first terminal establishes a broadcast connection with the second terminal; and finally, the first terminal establishes a data transmission channel through broadcast connection. The first terminal can display first prompt information to prompt passengers whether to allow the second terminal to establish broadcast connection with the first terminal under the condition that the second terminal receives the response to the broadcast synchronous information. The first prompt message includes device information of the second terminal, which can help the passenger determine whether the terminal currently requesting access to the broadcast is the second terminal used by the driver. If the passenger agrees to establish a broadcast connection with the second terminal, a confirmation operation of the first prompt message may be performed. Accordingly, the first terminal can establish a broadcast connection with the second terminal in response to the confirmation operation of the first hint information. The broadcast connection may be a bluetooth low energy broadcast connection. Since the first terminal can perform data transmission using the data transmission channel, the first terminal can establish the data transmission channel between the first terminal and the second terminal through the broadcast connection after the broadcast connection is established. The data transmission channel is a BIS channel, and is used for transmitting any data in the first terminal, such as an operation instruction or multimedia data corresponding to the operation instruction.

405. And responding to any operation instruction, and sharing the operation instruction to the second terminal by the first terminal through the data transmission channel.

In the embodiment of the application, after the establishment of the data transmission channel is completed, responding to any operation instruction triggered by the user in the first terminal, the first terminal can share the operation instruction to the second terminal through the data transmission channel. The operation instruction may be a play instruction and a volume adjustment instruction for the specified multimedia data, or may be an operation instruction for any function in the vehicle-mounted terminal, such as turning on or off an air conditioner of the target vehicle, which is not limited in the embodiment of the present application.

In some embodiments, in response to the operation instruction, the first terminal is capable of determining an instruction type of the operation instruction; then, under the condition that the operation instruction is determined to be the data sharing instruction based on the instruction type, the first terminal acquires data corresponding to the data sharing instruction; and finally, the first terminal shares the data corresponding to the data sharing instruction and the data sharing instruction to the second terminal through the data transmission channel, and the second terminal forwards the data corresponding to the data sharing instruction and the data sharing instruction to the vehicle-mounted terminal through Bluetooth connection so that the vehicle-mounted terminal executes the data sharing instruction based on the data corresponding to the data sharing instruction. The first terminal can determine the instruction type of the operation instruction before sharing the operation instruction to the second terminal because the operation instruction is any operation instruction triggered by the user in the first terminal. Under the condition that the instruction type is the data sharing type, the operation instruction is the data sharing instruction, so that the first terminal can acquire data corresponding to the data sharing instruction, and further share the data sharing instruction and the corresponding data to the second terminal through the data transmission channel.

For example, the data sharing instruction is a play instruction, and the data corresponding to the data sharing instruction is the multimedia data currently played by the first terminal. The first terminal can share the playing instruction and the currently played multimedia data to the second terminal, and the second terminal forwards the playing instruction and the currently played multimedia data to the vehicle-mounted terminal based on Bluetooth connection, so that the vehicle-mounted terminal plays the multimedia data based on the playing instruction.

In some embodiments, in a case that the operation instruction is determined to be a data switching instruction based on the instruction type, the first terminal can acquire data corresponding to the data switching instruction; and then, the first terminal shares the data corresponding to the data switching instruction and the data switching instruction to the second terminal through the data transmission channel, and the second terminal forwards the data corresponding to the data switching instruction and the data switching instruction to the vehicle-mounted terminal through Bluetooth connection so that the vehicle-mounted terminal switches the data currently processed into the data corresponding to the data switching instruction based on the data switching instruction. Under the condition that the instruction type of the operation instruction is the data switching type, the first terminal can determine that the operation instruction triggered by the user in the first terminal is the data switching instruction. Therefore, the first terminal can acquire the data corresponding to the data switching instruction, and further share the data switching instruction and the corresponding data to the second terminal through the data transmission channel.

For example, the data switching instruction is a switching instruction for the multimedia data currently played by the first terminal, and the data corresponding to the data switching instruction is the multimedia data played after the first terminal is switched. The first terminal can share the data switching instruction and the multimedia data played after the first terminal is switched to the second terminal, and the second terminal forwards the data switching instruction and the multimedia data played after the first terminal is switched to the vehicle-mounted terminal based on Bluetooth connection, so that the vehicle-mounted terminal switches the currently played multimedia data to the data corresponding to the data switching instruction based on the data switching instruction.

In some embodiments, under the condition that the operation instruction is determined to be a function acquisition instruction based on the instruction type, the first terminal can acquire and display a function interface of the vehicle-mounted terminal through the data transmission channel, wherein the function interface displays multiple functions of the vehicle-mounted terminal; then, in response to a trigger operation to any one of the functions in the function interface, the first terminal can control the in-vehicle terminal to execute the function based on the trigger operation. Under the condition that the instruction type of the operation instruction is the function acquisition type of any device, the first terminal can determine that the operation instruction triggered by the user in the first terminal is the function acquisition instruction of the vehicle-mounted terminal. Therefore, the first terminal can acquire the function interface of the vehicle-mounted terminal sent by the second terminal through the data transmission channel, and further display the function interface. The function interface displays various functions of the vehicle-mounted terminal, such as an air conditioner control function, a vehicle window control function, a multimedia playing function and the like. The user can trigger any function of the vehicle-mounted terminal in the function interface displayed by the first terminal. The first terminal is capable of controlling the vehicle-mounted terminal to execute the function based on the trigger operation in response to the trigger operation of the function. For example, the user performs an opening operation of an air-conditioning function in a function interface displayed by the first terminal, and the first terminal can control the in-vehicle terminal to open an air conditioner of the target vehicle.

Optionally, in response to a triggering operation on any function in the function interface, the first terminal can generate an operation instruction corresponding to the function based on the triggering operation, and then send the operation instruction corresponding to the function to the second terminal through the data transmission channel, and the second terminal forwards the operation instruction corresponding to the function to the vehicle-mounted terminal through bluetooth connection, so that the vehicle-mounted terminal can execute the operation instruction corresponding to the function.

In some embodiments, the first terminal may encrypt the data before sharing the data corresponding to the operation instruction. Correspondingly, the first terminal encrypts data corresponding to the operation instruction based on the broadcast code of the first terminal to obtain multimedia encrypted data; and then, the first terminal shares the encrypted data to the second terminal through the data transmission channel. The broadcast code of the first terminal may be a default broadcast code set by the user, or a broadcast code randomly generated by the first terminal based on the broadcast content, which is not limited in the embodiment of the present application. The broadcast code is used for encrypting or decrypting data corresponding to the operation instruction broadcast by the first terminal. Accordingly, before the passenger shares the data corresponding to the operation instruction through the first terminal, the data can be encrypted based on the broadcast code of the first terminal, and the encrypted data can be shared to the second terminal through the data transmission channel, so that other users can be prevented from directly acquiring the unencrypted data under the condition that the broadcast code of the first terminal is not acquired, and the safety of data transmission is improved.

Alternatively, the first terminal can provide the broadcast code to the second terminal by direct or indirect means. For example, the specific way to obtain the broadcast code may be to display the broadcast code directly on the first terminal, and the passenger can directly inform the driver of the broadcast code, and the broadcast code is input to the second terminal by the driver. Or the broadcast code can be displayed in a two-dimensional code form on the first terminal, and the second terminal can acquire the broadcast code of the first terminal by scanning the two-dimensional code.

In some embodiments, the first terminal may determine whether the operation instruction triggered by the user and the operation instruction currently executed by the vehicle-mounted terminal conflict. Correspondingly, responding to the operation instruction, the first terminal can acquire a target operation instruction through the data transmission channel, wherein the target operation instruction is an operation instruction currently executed by the vehicle-mounted terminal; then, under the condition that the operation instruction conflicts with the target operation instruction, the first terminal displays second prompt information, wherein the second prompt information is used for prompting that the operation instruction conflicts with the target operation instruction; and sharing the operation instruction to the second terminal through the data transmission channel under the condition that the operation instruction does not conflict with the target operation instruction. Before sharing the operation instruction to the second terminal, the first terminal can acquire the operation instruction currently executed by the vehicle-mounted terminal, namely the target operation instruction, sent by the second terminal through the data transmission channel. The target operation instruction may conflict with the operation instruction triggered by the user at the first terminal, so that the vehicle-mounted terminal cannot normally execute the operation instruction shared by the first terminal. Therefore, under the condition that the operation instruction shared by the first terminal conflicts with the target operation instruction, the first terminal can display the second prompt information so as to prompt the user that the operation instruction currently triggered conflicts with the operation instruction currently executed by the vehicle-mounted terminal. Under the condition that the operation instruction shared by the first terminal does not conflict with the target operation instruction, the first terminal can share the operation instruction to the second terminal directly through the data transmission channel, and then the operation instruction is forwarded to the vehicle-mounted terminal by the second terminal.

Optionally, any two operation instruction conflicts refer to that the two operation instructions perform operations with different operation types on the same operation object. If the currently executed operation instruction of the vehicle-mounted terminal is closing the window, the operation instruction triggered by the user in the first terminal is opening the window.

406. And the second terminal sends the operation instruction received through the data transmission channel between the first terminal and the second terminal to the vehicle-mounted terminal.

In the embodiment of the application, after receiving the operation instruction shared by the first terminal, the second terminal can send the operation instruction to the vehicle-mounted terminal through Bluetooth connection between the second terminal and the vehicle-mounted terminal, so that the vehicle-mounted terminal executes the operation instruction. Under the condition that the operation instruction is a play instruction for the appointed multimedia data, the requirement that the passenger wants to play the appointed multimedia data through the vehicle-mounted terminal can be met on the premise that the driver is not disturbed, and better audio-visual experience and riding experience are brought to the passenger.

In some embodiments, the second terminal can actively send a multimedia sharing request to the first terminal to request sharing of multimedia data of the first terminal in case of completion of the broadcast synchronization. Correspondingly, under the condition that the broadcasting synchronization is completed, the second terminal sends a multimedia sharing request to the first terminal through a data transmission channel, wherein the multimedia sharing request is used for requesting to share the multimedia data currently played by the first terminal; and under the condition that confirmation information of the first terminal on the multimedia sharing request is received, the second terminal sends the third multimedia data received through the data transmission channel to the vehicle-mounted terminal of the target vehicle, wherein the confirmation information is used for indicating the first terminal to share the currently played multimedia data with the second terminal. And under the condition that the broadcasting synchronization is completed, indicating that the second terminal has successfully accessed the first terminal, wherein the first terminal can establish a data transmission channel with the second terminal. Therefore, under the condition that the broadcasting synchronization is completed, if the second terminal does not receive the multimedia data shared by the first terminal within the duration threshold, the second terminal can send a multimedia sharing request to the first terminal through the data transmission channel so as to request the first terminal to share the multimedia data currently being played. After receiving the multimedia sharing request, the first terminal can display prompt information to prompt passengers whether to share the currently played multimedia data with the second terminal. And responding to the confirmation operation of the prompt information, the first terminal can return the confirmation information to the second terminal, and send the third multimedia data to the second terminal through the data transmission channel, and the third multimedia data is forwarded to the vehicle-mounted terminal by the second terminal so as to enable the vehicle-mounted terminal to play the third multimedia data. The third multimedia data may be audio or video, which is not limited in this embodiment of the present application.

In some embodiments, when receiving, through the data transmission channel, data corresponding to the operation instruction sent by the first terminal, the second terminal may determine whether the data corresponding to the operation instruction is encrypted data. Correspondingly, when the data corresponding to the operation instruction is not encrypted data, the second terminal can send the data corresponding to the operation instruction to the vehicle-mounted terminal through the first mode; when the data corresponding to the operation instruction is encrypted data, the second terminal can transmit the data corresponding to the operation instruction to the in-vehicle terminal in the following manner two.

Mode one: under the condition that the broadcasting synchronization is completed, the second terminal receives the operation instruction and data corresponding to the operation instruction through the data transmission channel; then, in the case where the second terminal establishes a bluetooth connection with the in-vehicle terminal of the target vehicle and the data corresponding to the operation instruction is not encrypted data, the second terminal can transmit the operation instruction and the data corresponding to the operation instruction to the in-vehicle terminal through the bluetooth connection. And when the data corresponding to the operation instruction is not encrypted data, the second terminal is indicated to be unnecessary to decrypt the data. And because the second terminal and the vehicle-mounted terminal are connected by Bluetooth, the second terminal can directly send the operation instruction and the data corresponding to the operation instruction to the vehicle-mounted terminal, and the vehicle-mounted terminal executes the operation instruction based on the data corresponding to the operation instruction.

Mode two: under the condition that Bluetooth connection is established between the second terminal and the vehicle-mounted terminal of the target vehicle and data corresponding to the operation instruction are encrypted data, the second terminal can decrypt the data corresponding to the operation instruction based on the broadcast code of the first terminal; and then, the second terminal sends the operation instruction and the data corresponding to the decrypted operation instruction to the vehicle-mounted terminal through Bluetooth connection, and the vehicle-mounted terminal executes the operation instruction based on the decrypted data. Under the condition that the data corresponding to the operation instruction are encrypted data, the second terminal can send the encrypted data to the vehicle-mounted terminal after decrypting the data corresponding to the operation instruction. Therefore, the second terminal can decrypt the data corresponding to the operation instruction based on the broadcast code of the first terminal, and further, the operation instruction and the decrypted data are transmitted to the vehicle-mounted terminal through the Bluetooth connection between the second terminal and the vehicle-mounted terminal, and the vehicle-mounted terminal executes the operation instruction based on the decrypted data.

407. And the vehicle-mounted terminal executes the operation instruction.

In the embodiment of the application, when the operation instruction is a play instruction for the appointed multimedia data, the vehicle-mounted terminal can perform operations such as demodulation, decoding, digital-to-analog conversion, audio amplification and the like on the multimedia data corresponding to the operation instruction after receiving the operation instruction sent by the second terminal, so that the multimedia data is played for passengers to listen.

For example, fig. 5 is a block diagram of a data sharing method according to an embodiment of the present application, and as shown in fig. 5, a first terminal used by a passenger of a target vehicle can broadcast audio data currently played to a second terminal through bluetooth. Because the second terminal is a terminal used by the driver of the target vehicle, the driver can always screen the navigation picture displayed by the second terminal to the vehicle-mounted terminal through Bluetooth connection between the second terminal and the vehicle-mounted terminal of the target vehicle. Therefore, after receiving the audio data of the first terminal, the second terminal can connect the navigation picture and the audio data through Bluetooth, together throw the screen to the vehicle-mounted terminal, and the vehicle-mounted terminal plays the screen. In order to make the data sharing method provided by the embodiment of the present application easier to understand, with continued reference to fig. 6, fig. 6 is an interaction flow diagram of data sharing provided by the embodiment of the present application. First, a first terminal serves as a broadcasting terminal, and during broadcasting of synchronization information through bluetooth, the terminal performs extended broadcasting and periodic broadcasting. When the second terminal is used as a broadcasting assistant, the second terminal can scan surrounding broadcasting sources and display broadcasting synchronous information of at least one broadcasting source device obtained by scanning. The driver can select the broadcast synchronization information of the first terminal therefrom to enable the second terminal to perform BIS synchronization with the first terminal based on the broadcast synchronization information of the first terminal. Under the condition that BIS synchronization is completed, in response to the first terminal playing music, the first terminal can establish a data transmission channel for transmitting the currently played music, and share the music of the first terminal to the second terminal in the form of a broadcast audio stream through the data transmission channel. Accordingly, at this time, the second terminal serves as a broadcast receiving end capable of receiving music of the first terminal through the data transmission channel. However, the second terminal can screen the navigation screen currently displayed by the second terminal to the in-vehicle terminal together with the music of the first terminal through the bluetooth connection with the in-vehicle terminal. After receiving the navigation picture and the music, the vehicle-mounted terminal can broadcast voice of the navigation picture while playing the music.
