Furthermore, terms such as "first" and "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0055] The current UWB technology is not mature enough. When UWB technology is applied to scenarios of high-definition audio and low-latency transmission, the advantages of UWB technology cannot be brought into play due to low transmission efficiency, which restricts the development of UWB technology in the field of audio transmission.

[0056] Based on this, the embodiments of the present application provide a data transmission method, device, storage medium and electronic device. Specifically, the data transmission device can be integrated into an electronic device, which can be a server or a terminal; wherein the terminal can include a mobile phone, a wearable smart device, a tablet computer, a laptop computer, and a personal computer (PC); the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms.

[0057] The following will describe the technical solutions of this application in detail through specific embodiments. It should be noted that the order of description of the following embodiments does not limit the priority order of the embodiments.

[0058] Please refer to Figure 1, which is a schematic diagram of the structure of a data transmission system provided in an embodiment of the present application. The data transmission system may include at least one transmitting end 1000 and at least one receiving end 2000.

[0059] The transmitting end 1000 can be connected to different receiving ends 2000 via a network. The transmitting end 1000 and the receiving end 2000 can be electronic devices with computing hardware that can support and execute software products corresponding to multimedia. It should be noted that the network can be a wireless network or a wired network, such as a wireless local area network (WLAN), a local area network (LAN), a cellular network, Bluetooth, a 2G network, a 3G network, a 4G network, a 5G network, etc.

[0060] In the embodiment of the present application, a transmitter 1000 and a receiver 2000 are connected to each other via UWB. The transmitter 1000 is a UWB transmitter, and the receiver 2000 is a UWB receiver. It should be noted that both the UWB transmitter and the UWB receiver can be electronic devices with UWB functionality.

[0061] During the specific implementation process, the sending end 1000 is used to send a data packet to the receiving end 2000, and the receiving end 2000 is used to receive the data packet sent by the sending end 1000 and feed back confirmation information to the sending end 1000.

[0062] In some embodiments, the transmitting end 1000 can be used to obtain audio data, and then segment the audio data to generate a number of data packets arranged in a time sequence. Afterwards, the current first data packet is processed to generate a target data packet. Afterwards, the transmitting end 1000 sends the target data packet to the receiving end 20000. It should be noted that the target data packet includes the time information of the current first data packet and the current second data packet. The current first data packet is the current head data packet, and the current second data packet is the next data packet arranged after the current first data packet. After the receiving end 2000 receives the target data packet, it can adjust the receiving timing of the next data packet according to the time information in the target data packet, so that the sending timing of the transmitting end 1000 is aligned with the receiving timing of the receiving end 2000.

[0063] That is, when the sending end 1000 starts to send a data packet, the receiving end 2000 is ready to receive the data packet; when the receiving end 2000 starts to feed back confirmation information, the sending end 1000 is ready to receive the confirmation information.

[0064] In summary, the data transmission system provided in the embodiment of the present application can send a target data packet carrying time information to the receiving end 2000 through the sending end 1000, so that the receiving end 2000 adjusts the receiving timing of the next data packet according to the time information, thereby aligning the sending timing of the sending end 1000 and the receiving timing of the receiving end 2000, saving the total time required for data transmission and improving data transmission efficiency.

[0065] Please refer to Figure 2, which is a flow chart of a data transmission method provided in an embodiment of the present application. It should be noted that the data transmission method is applied to the sending end, and the specific flow of the data transmission method can be as follows:

[0066] 101. Get the current source data.

[0067] In the embodiment of the present application, the current source data is audio data. The audio data refers to data transmitted via audio. It should be noted that the audio data includes but is not limited to original lossless audio recorded in real time by an audio recording device with network functionality.

[0068] The audio recording device may be integrated into the transmitting end, and the transmitting end may directly obtain the audio data through the audio recording device. The audio recording device may also be a device independent of the transmitting end, and the audio data may be collected by the audio recording device, and then the transmitting end may obtain the audio data from the audio recording device through data exchange.

[0069] 102. Split the current source data into at least two data packets and cache them in time sequence.

[0070] In some embodiments, the current source data may be randomly segmented to obtain a number of data packets of equal or unequal lengths, each data packet then being compressed according to a first target compression ratio, and the compressed data packets being cached in time sequence.

[0071] It is understood that in the embodiment of the present application, the current source data is audio data, and therefore each data packet obtained by segmentation has a corresponding time sequence. In a specific implementation, each data packet can be stored in the corresponding buffer area in the order of the time sequence. For example, the data packet with the first time sequence is stored in the first buffer area, the data packet with the second time sequence is stored in the second buffer area, and the data packet with the third time sequence is stored in the third buffer area.

[0072] It should be noted that the first, second and third timings are sequentially increased. When sending data packets, the transmitting end sends the data packets in the first buffer area, the data packets in the second buffer area and the data packets in the third buffer area in sequence.

[0073] 103. Obtain time information of a current second data packet, where the current second data packet is the next data packet arranged after the current first data packet.

[0074] Specifically, the data packet length of the current second data packet may be obtained; and the time information of the current second data packet may be obtained according to the data packet length.

[0075] In some embodiments, the time information of a large number of data packets with different packet lengths can be sampled in advance, and then a data query table can be constructed based on the correspondence between the packet length and the time information. The packet length can then be input into the data query table for matching to obtain the corresponding time information.

[0076] It can be understood that the current first data packet refers to the data packet that is first in the current time sequence, and the current second data packet refers to the data packet that is second in the current time sequence.

[0077] It should be noted that the time information includes the sending preparation time and the air transmission time.

[0078] 104. Perform data processing based on the time information and the current first data packet to generate a target data packet.

[0079] Specifically, the sending preparation time and the air transmission time may be encapsulated to generate identification information; and then the identification information is merged with the current first data packet to generate a target data packet.

[0080] In the embodiment of the present application, the identification information is header information, that is, information placed in the header of a data packet.

[0081] 105. When receiving the data sending instruction, the target data packet is sent to the receiving end, so that the receiving end adjusts the receiving timing of the next data packet according to the time information.

[0082] When the sending preparation time of the target data packet arrives, the sending end will receive a data sending instruction to instruct the sending end to send the target data packet, so that the receiving end adjusts the receiving timing of the next data packet according to the time information, that is, the sending timing of the sending end and the receiving timing of the receiving end are aligned, thereby saving the total time required for data transmission and improving data transmission efficiency.

[0083] In some embodiments, after the target data packet is sent, the transmitting end may prepare to send the next data packet. In other words, after the target data packet is sent, the process may return to step 103 and continue until all data packets are sent.

[0084] In another embodiment, after receiving the target data packet, the receiving end generates corresponding confirmation information and feeds it back to the transmitting end. The transmitting end can determine the current transmission status by counting the confirmation information from the receiving end within a preset time period, thereby confirming whether the packet length of the remaining data packets needs to be adjusted. The confirmation information carries the first transmission efficiency of the target data packet.

[0085] In a specific implementation process, after receiving the confirmation information, the receiving end can obtain the second transmission efficiency of the target data packet, thereby determining whether the first transmission efficiency is consistent with the second transmission efficiency, and confirming whether the data transmission efficiency is optimal.

[0086] Specifically, after step 105, it may also include: when receiving confirmation information fed back by the receiving end, obtaining the first transmission efficiency and the second transmission efficiency of the target data packet; comparing the first transmission efficiency and the second transmission efficiency, and confirming whether to adjust the packet length of the remaining data packets based on the comparison result; after adjusting the packet length of the remaining data packets or when it is determined that the packet length of the remaining data packets is not adjusted, returning to the step of obtaining the time information of the current second data packet until the transmission of all data packets is completed.

[0087] It should be noted that the first transmission efficiency is the target data transmission efficiency calculated by the receiving end based on the target data packet receiving cycle, data packet size, index continuity in the identification information, etc. The second transmission efficiency is the data transmission efficiency of the sending end itself.

[0088] It is understood that when the first transmission efficiency and the second transmission efficiency are consistent, the data transmission efficiency between the receiving end and the transmitting end is optimal. In this case, there is no need to adjust the packet lengths of the remaining data packets, and the process can directly return to step 103. When the first transmission efficiency and the second transmission efficiency are inconsistent, the data transmission efficiency between the receiving end and the transmitting end is not optimal. In this case, the number of inconsistencies can be counted, and when the number of inconsistencies reaches a threshold, the packet lengths of the remaining data packets can be adjusted. After the packet lengths of the remaining data packets are adjusted, the process can return to step 103.

[0089] That is, when the number of times the first transmission efficiency and the second transmission efficiency are inconsistent does not reach the threshold, there is no need to adjust the data packet lengths of the remaining data packets, and the process can directly return to step 103 .

[0090] It should be noted that the threshold value can be set according to actual conditions and is not limited in the present embodiment. For example, the threshold value can be 1 time, 2 times, 3 times, 4 times, 5 times, etc.

[0091] It can be understood that in the specific implementation process, the data packet length can be adjusted by decompressing or recompressing the remaining data packets according to the second target compression ratio, so as to achieve dynamic adjustment of the compression ratio of the data packet according to the current transmission status, thereby improving the flexibility of data transmission, so that multiple data packets can be transmitted in a timely manner, improving the efficiency of data transmission, and thus overcoming the problem of low data transmission efficiency in related technologies.

[0092] It should be noted that the compression ratio includes, but is not limited to, corresponding to a compression format. That is, when compressing or decompressing a data packet, the compression format used is adjusted, thereby achieving a target compression format (having a target compression ratio) whose compression ratio is compatible with the current transmission conditions by using different compression formats.

[0093] In summary, the data transmission method provided by the embodiment of the present application includes obtaining the current source data; dividing the current source data into at least two data packets and caching them according to the timing; obtaining the time information of the current second data packet, the current second data packet being the next data packet arranged after the current first data packet; performing data processing based on the time information and the current first data packet to generate a target data packet; upon receiving a data sending instruction, sending the target data packet to the receiving end so that the receiving end adjusts the receiving timing of the next data packet according to the time information. This solution can obtain the time information of the current second data packet before sending the current first data packet, and generate a target data packet based on the time information and the current first data packet, and then send the target data packet to the receiving end so that the receiving end adjusts the receiving timing of the next data packet according to the time information, so that the sending timing of the sending end and the receiving timing of the receiving end are aligned, thereby saving the total time required for data transmission and improving data transmission efficiency.

[0094] Referring to FIG. 3 , another embodiment of the present application further provides another data transmission method. It should be noted that this data transmission method is applied to the receiving end. The specific process of this data transmission method may be as follows:

[0095] 201. Receive a target data packet sent by a sender.

[0096] 202. Obtain identification information of the target data packet.

[0097] 203. Decapsulate the identification information to generate time information of the target data packet.

[0098] 204. Adjust the receiving timing of the next data packet according to the time information to align the receiving timing of the own end with the sending timing of the sender.

[0099] In some embodiments, after receiving the target data packet, the receiving end generates corresponding confirmation information and feeds it back to the transmitting end. The transmitting end can determine the current transmission status by counting the confirmation information from the receiving end within a preset time period, thereby confirming whether the packet length of the remaining data packets needs to be adjusted. The confirmation information carries the first transmission efficiency of the target data packet. That is, after step 104, the following steps may also be included:

[0100] Generate confirmation information and feed it back to the sender.

[0101] It should be noted that the first transmission efficiency is the target data transmission efficiency calculated by the receiving end according to data such as the receiving period of the target data packet, the data packet size, and the index continuity in the identification information.

[0102] In summary, the data transmission method provided in the embodiments of the present application includes receiving a target data packet sent by a transmitter, obtaining identification information of the target data packet, decapsulating the identification information, generating time information of the target data packet, and adjusting the reception timing of the next data packet based on the time information to align the receiving timing of the next data packet with the sending timing of the transmitter. After receiving the target data packet, this solution can adjust the reception timing of the next data packet based on the time information in the target data packet, so that the sending timing of the transmitter and the receiving timing of the receiver are aligned, thereby saving the total time required for data transmission and improving data transmission efficiency.

The data transmission device may include a first acquisition unit 301, a data segmentation unit 302, a second acquisition unit 303, a data processing unit 304 and a data sending unit 305.

[0107] A second acquiring unit 303 is configured to acquire time information of a current second data packet, where the current second data packet is the next data packet arranged after the current first data packet;

[0109] The data sending unit 305 is configured to send the target data packet to the receiving end upon receiving the data sending instruction, so that the receiving end adjusts the receiving timing of the next data packet according to the time information.

This solution can obtain the time information of the current second data packet before sending the current first data packet, and generate a target data packet based on the time information and the current first data packet, and then send the target data packet to the receiving end, so that the receiving end adjusts the receiving timing of the next data packet according to the time information, so that the sending timing of the sending end and the receiving timing of the receiving end are aligned, thereby saving the total time required for data transmission and improving data transmission efficiency.

The processor 608 executes various functional applications and information processing by running the software programs and modules stored in the memory 602. The memory 602 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area may store data created according to the use of the electronic device (such as audio data, a phone book, etc.). In addition, the memory 602 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage device. Accordingly, the memory 602 may also include a memory controller to provide the processor 608 and the input unit 603 with access to the memory 602.

[0123] The input unit 603 can be used to receive input digital or character information and generate keyboard, mouse, joystick, optical, or trackball signal input related to user settings and function control. Specifically, in one embodiment, the input unit 603 may include a touch-sensitive surface and other input devices. A touch-sensitive surface, also known as a touch display or touchpad, can detect user touch operations on or near it (for example, operations performed by a user using a finger, stylus, or any other suitable object or accessory on or near the touch-sensitive surface) and drive corresponding connected devices according to a pre-set program. Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. The touch detection device detects the user's touch direction and detects signals generated by the touch operation, transmitting the signals to the touch controller. The touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 608. It can also receive and execute commands from the processor 608. In addition, touch-sensitive surfaces can be implemented using various types, such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch-sensitive surface, the input unit 603 may also include other input devices. Specifically, other input devices may include, but are not limited to, one or more of a physical keyboard, function keys (such as a volume control key, a switch key, etc.), a trackball, a mouse, a joystick, and the like.

Optionally, the display panel can be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. Further, the touch-sensitive surface can cover the display panel. When the touch-sensitive surface detects a touch operation on or near it, it is transmitted to the processor 608 to determine the type of touch event. The processor 608 then provides a corresponding visual output on the display panel based on the type of touch event. Although in Figure 6, the touch-sensitive surface and the display panel are implemented as two independent components to implement input and output functions, in some embodiments, the touch-sensitive surface and the display panel can be integrated to implement input and output functions.

It can be used for applications that recognize the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that the electronic device can also be configured with, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described in detail here.

[0126] Audio circuit 606, speakers, and microphones provide an audio interface between the user and the electronic device. Audio circuit 606 converts received audio data into electrical signals and transmits them to the speaker, which then converts them into sound signals for output. The microphone, on the other hand, converts collected sound signals into electrical signals, which are then received by audio circuit 606 and converted into audio data. The audio data is then processed by output processor 608 and transmitted via RF circuit 601 to, for example, another electronic device. Alternatively, the audio data is output to memory 602 for further processing. Audio circuit 606 may also include an earphone jack to allow communication between external headphones and the electronic device.
