It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

Referring to fig. 1, a block diagram of a speech system 1 according to an embodiment of the present application is shown. Specifically, the speech system 1 includes an electronic apparatus 100 and a wireless audio playback apparatus 200.

In the embodiment of the present invention, an application capable of playing audio is installed in the electronic device 100, and specifically, the application may be audio playing software, video playing software, or call software. The electronic device 100 sends the audio to be played to the wireless audio playing device 200, and the wireless audio playing device 200 plays the voice.

The wireless audio playing device 200 is a device for playing audio, which is independent from the electronic device 100 and is capable of receiving and playing audio data sent by the electronic device 100. For example: when a user uses the electronic device to play a song, the user may start a music playing application program on a display interface of the electronic device 100, or play a locally stored song by using a player of an operating system of the electronic device 100, the electronic device 100 processes the song during the process of playing the song to obtain digitized audio data and sends the processed audio data to the wireless audio playing device 200, and the wireless audio playing device 200 performs digital-to-analog conversion on the audio data after receiving the audio data to obtain an analog signal, and plays the analog signal by using a playing function of an external sound device, so as to realize song playing through the external sound device.

In the embodiment of the present invention, the electronic device 100 and the wireless audio playing device 200 interact with each other through a wireless network to transmit signals, wherein the wireless network may be a bluetooth, wifi, LTE network, or NFC.

In this embodiment of the present invention, the wireless audio playing device 200 is a bluetooth sound device or a bluetooth earphone, the wireless audio playing device 200 can realize connection with the electronic device 100 by starting a bluetooth function, and after the connection is established, the electronic device 100 sends the voice to be played to the bluetooth sound device, so that the bluetooth sound device realizes voice playing.

Specifically, after the bluetooth functions of the electronic device 100 and the wireless audio playing device 200 are started, the electronic device 100 searches for bluetooth devices within a preset distance of the electronic device 100 and displays names of the searched bluetooth devices on a display interface of the electronic device, after a user clicks or selects the wireless audio playing device 200 on the display interface, the electronic device 100 sends a connection request to the wireless audio playing device 200, and after receiving the connection request, the wireless audio playing device 200 establishes a connection with the electronic device 100 and feeds back a connection success message.

After the electronic device 100 establishes connection with the wireless audio playing device 200, if the electronic device 100 has audio such as a song or a video that needs to be played, the electronic device processes the audio data into a digital signal and sends the audio data to the wireless audio playing device 200, and after receiving the audio data, the wireless audio playing device 200 processes and plays the audio data, thereby playing the audio. Specifically, the electronic device 100 needs to encode the audio data and then transmit the encoded audio data to the wireless audio playback device 200, specifically, the electronic device 100 and the wireless audio playback device 200 are connected via bluetooth, and data and instructions between the electronic device 100 and the wireless audio playback device 200 are transmitted according to a certain bluetooth protocol, when the electronic device 100 transmits the audio data to the wireless audio playback device 200, the audio data needs to be encoded according to an encoding format under the supported bluetooth protocol, for example, for audio, an Apt-X, SBC, AAC, or LDAC encoding algorithm is often used.

The electronic device 100 encodes the Audio data to generate an Audio data packet, and then transmits the Audio data packet to the wireless Audio playback device 200 through a bluetooth transmission channel between the electronic device 100 and the wireless Audio playback device 200, and after the wireless Audio playback device 200 acquires the Audio data packet, the wireless Audio playback device 200 can acquire the Audio data packet by decoding the data packet, for example, SBC, which is an encoding format mandatory by an A2DP (Advanced Audio Distribution Profile, bluetooth Audio transmission protocol) protocol. All bluetooth can support the protocol, so all bluetooth audio chips can also support the protocol, taking MP3 format audio as an example, the encoding process is that the electronic device samples and discretizes an MP3 file after PCM encoding, converts the MP3 file into an SBC encoding format, then sends the SBC encoding format to the wireless audio playing device, the wireless audio playing device decodes the SBC format audio to obtain PCM format audio data, and drives components such as a voice coil of the wireless audio playing device to vibrate and sound according to the PCM encoding.

Further illustratively, if the user a makes a call to the user B by using the electronic device 100, and the call is connected, the electronic device 100 used by the user a receives the voice transmitted by the electronic device of the user B, and the electronic device 100 used by the user a transmits the received voice to the wireless audio playing device 200, and the voice is played by the wireless audio playing device 200, so that the user a can hear the voice of the user B. As an embodiment, a microphone is disposed on the wireless audio playing device 200, when the user a speaks, the wireless audio playing device 200 will collect the sound of the user a and generate voice, and send the generated voice to the electronic device 100 of the user a, and the voice is sent to the electronic device used by the user B by the electronic device 100, so that the conversation between the user a and the user B can be realized.

Further exemplarily, when the user a performs a video session with the user B by using the instant messaging software installed in the electronic device 100, the electronic device 100 of the user a receives video data sent by the electronic device of the user B, the electronic device 100 processes the video data to obtain video picture data and video sound data, wherein the electronic device 100 displays the video picture data on a display interface and sends the video sound data to the wireless audio playback device 200 connected to the electronic device 100, the wireless audio playback device 200 synchronously plays the video sound data, a camera on the electronic device 100 collects a captured video image, the wireless audio playback device 200 collects a sound during the speech of the user a to obtain voice data, and the wireless audio playback device 200 sends the collected voice data to the electronic device 100, the electronic device 100 processes the video image collected by the camera and the voice data collected by the wireless audio playing device 200 to obtain video data, and feeds the video data back to the electronic device used by the user B, so that the electronic device used by the user B can complete video playing, and video conversation between the user a and the user B is realized.

At present, the inconvenience brought by wired earphones can be reduced by playing audio data in electronic equipment by using wireless audio playing equipment, but the inventor finds that, when the wireless audio playing equipment is used for playing audio, the audio is transmitted through a wireless network such as bluetooth, so that the audio has time delay, particularly when the video is played, the playing of a video picture is played after being analyzed by the electronic equipment, and the audio corresponding to the video needs to be transmitted to the wireless audio playing equipment after a series of operations such as coding and the like by the electronic equipment, and in the transmission process, the time delay exists, for example, the time delay is about 100 and 300ms, so that the picture and the audio are not synchronous, for example, the bullet sound in a gunfight game in a game picture is delayed, and the user experience is greatly reduced.

The inventor finds out in research that one reason for the above delay is that, due to the transmission between the electronic device and the wireless audio playing device via the bluetooth transmission protocol, in order to ensure the integrity of the data, when the data is sent from the sending end to the receiving end, if the receiving end receives the data, an identifier indicating that the data has been received, for example, a parameter variable, is fed back by the receiving end. If the receiving end does not receive the data and feeds back an identifier for indicating that the data is not received, the sending end sends the data once again, namely, the data is a retransmission mechanism under the Bluetooth transmission protocol. Although the mechanism can ensure that the data of the sending end is sent to the receiving end more completely, and the receiving end is prevented from missing the data, the data can be received by the receiving end in a delayed manner when the data is sent repeatedly, and meanwhile, the data after the data in the sending sequence can also be received in a delayed manner. If the retransmission mechanism is adopted when the wireless audio playing device plays the audio data sent by the electronic device, the audio signal is delayed, so that the picture and the audio are not synchronous, and the user experience is reduced.

Therefore, in order to solve the above problem, referring to fig. 2, an embodiment of the present application provides a data transmission method applied to an electronic device, and specifically, the method includes: s201 to S203.

S201: when the electronic equipment is connected with the wireless audio playing equipment, whether the electronic equipment receives a playing request of audio data or not is detected.

When the bluetooth function of the electronic device is turned on, the electronic device scans the bluetooth devices within a certain distance range around, and specifically, after receiving a scanning command, a bluetooth chip or other underlying network modules of the electronic device scans according to a preset channel scanning sequence, such as scanning common channels 1, 7, and 13 first, and then scanning other channels that are not common, thereby obtaining the identifiers of all bluetooth devices within the current range, and displaying the identifiers in a bluetooth list interface of the electronic device.

If the Bluetooth device which is already connected and has better signal strength exists in the scanned Bluetooth device identification, the electronic device can automatically connect with the Bluetooth device, and the user can also select one Bluetooth device in the Bluetooth list interface for connection.

When the electronic device is connected with an external Bluetooth device, a system of the electronic device acquires a state value indicating that the electronic device is currently connected with the Bluetooth device. Therefore, the electronic device can detect the connected Bluetooth device, and acquire the device identifier of the Bluetooth device.

After the device identifier of the connected bluetooth device is obtained, it is determined whether the connected bluetooth device is a wireless audio playing device according to the device identifier, specifically, the device identifier may include a name or a brand of the device, for example, it can be determined whether the device is a wireless audio playing device such as an earphone or a sound device according to the device identifier, so as to determine whether the wireless audio playing device is connected. In addition, the device identifier of the connected bluetooth device may be determined, and then the device type corresponding to the currently connected device identifier is obtained from the preset correspondence between the device identifier and the device type, so that whether the currently connected device type is the wireless audio playing device or not can be determined.

When the electronic device is determined to be connected with the wireless audio playing device, that is, after the electronic device is connected with the wireless audio playing device, whether the electronic device receives a playing request is detected, wherein the playing request is a request for requesting to play audio data.

Specifically, the play request may be a reminder message or a voice play request. The reminding information comprises information for reminding a user that some events are triggered, such as call reminding information, short message reminding information, alarm reminding information and the like. For example, the call reminding information is used for reminding the user of the current incoming call.

As another embodiment, the utterance request may be a request to play a voice every time the electronic device utters a voice. The utterance request may be an audio utterance request, a video utterance request, or a call utterance request.

Specifically, a plurality of audio playing software are installed in the electronic device, and the software may be a music playing APP, a video playing APP, or a recording APP. For example, a video playing key is arranged on a video playing interface, and by detecting the touch of the video playing key, whether the electronic device currently receives a playing request of audio data can be determined, for example, a user selects a video, enters the video playing interface, and clicks a playing button of the playing interface, and an application program can detect what type of video the user currently clicks through monitoring the user touch operation, specifically, the playing button is provided with a preset attribute, and by detecting the attribute of the obtained playing button corresponding to the touch operation, the video to be played selected by the user can be determined, so that the playing request and the audio corresponding to the playing request can be obtained.

S202: and reducing the upper limit times of data retransmission between the electronic equipment and the wireless audio playing equipment.

If a play request is received, it indicates that the current electronic device is in a state of preparing to play audio data, and then an upper limit number of data retransmission between the electronic device and the wireless audio playing device is obtained, specifically, the upper limit number of data retransmission is related to a bluetooth protocol used between the electronic device and the wireless audio playing device, and the upper limit number of data retransmission corresponding to the protocol is generally a fixed numerical value corresponding to the protocol, for example, the upper limit number of data retransmission is 3.

In addition, when audio data is transmitted, the audio data is encoded into a plurality of audio data packets, and the plurality of audio data packets are sent to the wireless audio playing device according to a certain data sending sequence, specifically, whether a target audio data packet sent to the wireless audio playing device by the electronic device is lost is detected, where the target audio data packet is one of a plurality of data packets corresponding to the audio data to be played by the electronic device. If the state value is not received within a certain time, the electronic device determines that the wireless audio playing device has not successfully received the target audio data packet, that is, the target audio data packet sent to the wireless audio playing device by the electronic device is lost, and then determines whether the transmission times corresponding to the audio data packet are less than the upper limit times of data retransmission. The transmission times is the number of times of sending the target audio data packet, specifically, the number of times of sending the target audio data packet, during the process of sending the audio data to the wireless audio playing device by the electronic device this time, and the number of times of sending the target audio data packet is allowed to be modified as the sending times change, for example, a parameter value s is set, and the parameter value s is used for recording the number of times of sending the target audio data packet, that is, if 1 time is sent, s is 1. After the target data packet is successfully sent, s is cleared. Assuming a parameter value d, which is used to indicate the upper limit number of data retransmissions, e.g. the upper limit number of data retransmissions is 3, the parameter value d is 3. And comparing s with d to judge the size between the two.

If the transmission times corresponding to the audio data packets are judged to be less than the upper limit times of data retransmission, the target audio data packets are sent to the wireless audio playing equipment again; and if the target audio data packet is larger than or equal to the preset data transmission sequence, stopping transmitting the target audio data packet, and transmitting the audio data after the target audio data packet to the wireless audio playing equipment according to the preset data transmission sequence.

Specifically, it is assumed that packet 1, packet 2, packet 3, packet 4, packet 5, and the like are included in the data transmission sequence. Taking the target audio data packet as the data packet 1 as an example, after the data packet 1 fails to be transmitted, if the number of transmission times of the data packet 1 is greater than the upper limit number of data retransmission, the data packet 1 is discarded, and the data packet 2 and the subsequent data packets are continuously transmitted.

It can be seen that increasing the upper limit number of data retransmission can ensure the integrity of data transmission and avoid losing a certain data, while if decreasing the upper limit number of data retransmission, although a certain data will be lost, the acquisition delay of the data after the data will be reduced, for example, if the data packet 1 is immediately discarded after a transmission failure and the data packet 2 is transmitted, although the data packet 1 is lost, the data packet 2 can be quickly obtained without waiting until the data packet 1 is attempted to be transmitted again.

Therefore, in the embodiment of the present application, in order to reduce the delay of audio playing, the upper limit number of data retransmission between the electronic device and the wireless audio playing device is reduced. As an embodiment, the upper limit number of data retransmissions between the electronic device and the wireless audio playing device is modified to a preset number, where the preset number is 1 or 0, specifically, if the upper limit number of data retransmissions is greater than 1, the upper limit number of data retransmissions may be modified to 1 or 0, and if the upper limit number of data retransmissions is equal to 1, the upper limit number of data retransmissions may be modified to 0.

S203: and sending the audio data to the wireless audio playing equipment according to the reduced upper limit times of data retransmission, and instructing the wireless audio playing equipment to play the audio data.

Specifically, whether an audio data packet sent by the electronic device to the wireless audio playing device is lost is detected; if so, judging whether the transmission times corresponding to the audio data packet are less than the reduced upper limit times of data retransmission; if the number of the audio data packets is smaller than the preset number, the audio data packets are sent to the wireless audio playing equipment again; and if the number of the audio data packets is larger than or equal to the number of the audio data packets, stopping sending the audio data packets, and sending the audio data after the audio data packets to the wireless audio playing equipment according to a preset data sending sequence. The preset data transmission sequence is a transmission sequence of a plurality of data packets obtained by dividing audio data acquired by the electronic device, and the transmission data can be divided according to a time axis of audio playing.

In addition, it should be noted that, when the electronic device sends the non-audio data to the wireless audio playing device, the upper limit number of data retransmission used may be used instead of being reduced, and a default upper limit number may be used.

Therefore, by reducing the upper limit times of data retransmission, the time delay of sending the whole audio data to the wireless audio playing device due to the excessive times of retransmitting a certain data packet in the audio data can be avoided.

Specifically, on the basis of the foregoing embodiments, the method of the present application may also be applied to audio data playing corresponding to image data, so as to avoid asynchronous sound and picture, and specifically, referring to fig. 3, a data transmission method is shown, which is applied to an electronic device, and specifically, the method includes: s301 to S304.

S301: when the electronic equipment is connected with the wireless audio playing equipment, whether the electronic equipment receives a playing request of audio data or not is detected.

S302: and judging whether the audio data belongs to the audio data played corresponding to the image data.

Specifically, the audio data may be data corresponding to an independent audio file, for example, a song or a recording in mp3 or flac format, or may be video data, specifically, the video data includes image data and audio data played corresponding to the image data, specifically, the video includes multi-frame image data and audio data, when the video data is played, the multi-frame image data is displayed by a display device of the electronic device or a peripheral display device connected to the electronic device, and the audio data is played by an audio player, for example, a wireless audio playing device, specifically, a playing time point of one frame of the image data corresponds to a playing time point of one audio data, and the image and the audio in the video can be separated by some software.

It is considered that if the audio data played corresponding to the image data is played with a delay, the audio and image data will be out of synchronization, which affects the viewing experience of the user. Therefore, after it is detected that the electronic device receives a play request of audio data, it is determined whether the audio data belongs to audio data played corresponding to the image data.

As an embodiment, an identifier of an application program that sends the playback request of the audio data may be obtained, whether the identifier of the application program belongs to audio-only software or video-only software may be determined, and if the identifier belongs to video-only software, whether the audio data belongs to audio data that is played in correspondence with the image data may be determined.

As another example, since there is some software that can play both video and pure audio, judging whether the audio data belongs to the audio data played corresponding to the image data by judging whether the video is played currently, specifically, when the electronic device plays the video, extracting the audio data played corresponding to the image data and sending the audio data to an audio processing module in the system to call an audio processing circuit in the electronic device, that is, the audio data is sent to the audio processing circuit for audio encoding and other operations, so that after receiving a play request of the audio data, it is determined whether the video is currently being played, if yes, it means that the audio to be played currently belongs to the audio data in the video being played currently, that is, the audio data belongs to the audio data played corresponding to the image data.

In another embodiment, the electronic device performs video playing procedures including data de-agreement and de-encapsulation, then performs audio decoding and image decoding, sends the decoded audio data to the audio playing device for playing, and sends the image data to the video playing device for playing. Therefore, in order to facilitate synchronous playing of images and audio, similar identifiers are set for audio data and video frames played corresponding to image data, for example, the audio and video frames both use an identifier format of a + B, where a is a preamble and is used to indicate that the audio and video frames belong to a certain video, and when the audio data to be played is acquired, whether the audio corresponds to an image frame, that is, whether the audio belongs to the audio data played corresponding to the image data can be determined according to the format of the identifier of the audio data.

After determining that the audio data belongs to the audio data played corresponding to the image data, operation S303 is performed.

In addition, considering that in different video types, not all videos need to reduce the upper limit number of data retransmissions to transmit the audio data corresponding to the video, specifically, if the audio data belongs to the audio data played corresponding to the image data, a specific implementation manner of reducing the upper limit number of data retransmissions between the electronic device and the wireless audio playing device may be: if the audio data belong to the audio data played corresponding to the image data, determining the video type of the target video corresponding to the audio data, and judging whether the video type is a preset video type; and if the video type is the preset video type, reducing the upper limit times of data retransmission between the electronic equipment and the wireless audio playing equipment.

Specifically, the target video corresponding to the audio data is determined, and specifically, the target audio matching the identifier of the audio data may be determined according to the identifier of the audio data, such as the identifier format of a + B described above, where a is a preamble and is used to indicate that a video belongs to a certain video. Thus, the target video corresponding to the audio data can be determined. Then, the type of the target video is determined, specifically, the video includes summary information, the content of the video can be determined through the summary information, and it is convenient to classify the video and find the video through the summary information, specifically, the summary information may be an image of a certain frame in the video, or may be a text description. The type of the video can be determined according to the summary information, for example, the content indicated by the summary information includes description of the video content, and the type of the video is determined according to the video content, for example, the type of the video can be a game type, a movie, a television series, a video call, and the like.

In addition, after the audio data is determined to belong to the audio data played corresponding to the image data, the target video corresponding to the audio data is determined, then the application program corresponding to the target video is determined, and the video type of the target video is determined according to the application program. Specifically, the implementation manner of determining the video type of the target video corresponding to the audio is as follows: determining a target video corresponding to the audio data, determining the type of an application program playing the target video, and determining the video type of the target video according to the type of the application program.

Specifically, after acquiring the identifier of the application program of the target video, the type of the application program is determined according to the identifier, wherein the identifier of the application program may be a package name, a name, and the like of the application program. For example, the electronic device stores in advance the correspondence between the identifier of the application program and the category of the application program, as shown in table 1 below:

TABLE 1

Identification of applications	Categories of applications
		Apk1	Game machine
Apk2	Video
		Apk3	Audio frequency

Thus, the type of the application program corresponding to the target video can be specified from the correspondence between the application program identifier and the type of the application program shown in table 1. For example, in the embodiment of the present application, a game screen of game software of an electronic device is played through a wireless audio playing device, where the game screen includes an image and music, and the music may be game music, game sound effects, and the like, and for example, the game sound effects may be a gunshot sound or a footstep sound. As an embodiment, the audio data may be a game sound, the application corresponding to the game sound is a certain game APP, the category to which the application belongs is a game type, and then the video type of the target video is determined according to the type of the application, specifically, the type of the application may be taken as the video type of the target video, for example, the type of the application is a game, and the video type of the target video is also a game.

In one embodiment, the type of the application may be a type set for the application by a developer of the application when the developer of the application is open, or a type set for the application by a user after the application is installed on the electronic device. Which category the application belongs to in particular may be set by the user as desired, for example, the user may set a certain social software to an audio category, or to a video category, or to a social category.

In addition, application installation software, such as Appstore in ios systems, is installed in the electronic device. An application list is provided within the application installation software where the user can download applications and update and open applications, and the application installation software can display different applications by category, such as audio, video, or game. Therefore, the user can already know the category of the application when installing the application using the application installation software. Furthermore, if some application programs can play video and can also play audio, the type of the application program is set as the video type if the application program supports the function of video playing, and the type of the application program is set as the audio type if the application program does not support the function of video playing but only supports the function of audio playing. Specifically, whether the application supports the video playing function or not may be determined by determining whether the application supports the video playing function according to the function description included in the function description information of the application, for example, the supported playing format, or by detecting whether the video playing module is played in the program module of the application, for example, a certain video playing codec algorithm, and the like.

As another embodiment, if some application programs can play video and audio, for example, some video playing software can play audio-only files and also video, the category of the application program can be determined according to the usage record of the application program, that is, according to the usage record of the application program within a certain period of time, it is determined whether the user tends to play video or more tends to play audio by using the application program.

Specifically, operation behavior data of all users of the application program within a preset time period is obtained, where all users refer to all users who have installed the application program, and the operation behavior data may be obtained from a server corresponding to the application program, that is, when a user uses the application program, the user logs in the application program using a user account corresponding to the user, and the operation behavior data corresponding to the user account is sent to the server corresponding to the application program, and the server stores the obtained operation behavior data in correspondence with the user account. In some embodiments, the electronic device sends an operation behavior query request for an application program to a server corresponding to the application program, and the server sends operation behavior data of all users within a certain preset time period to the electronic device.

The operation behavior data comprises the name and time of the played audio file and the name and time of the played video file, the number and total time of the audio file played by the application program in a certain preset time period can be determined by analyzing the operation behavior data, the number and total time of the video file played by the application program can also be obtained, the category of the application program is determined according to the ratio of the total playing time of the audio and video files in the preset time period, specifically, the ratio of the total playing time of the audio and video files in the preset time period is obtained, for convenience of description, the ratio of the total playing time of the audio file in the preset time period is recorded as the audio playing ratio, the ratio of the total playing time of the video file in the preset time period is recorded as the video playing ratio, if the video playing ratio is greater than the audio playing ratio, the category of the application program is set as the video type, and if the audio play proportion is greater than the video play proportion, the category of the application program is set as the audio type. For example, if the preset time period is 30 days, that is, 720 hours, and the total playing time of the audio file is 200 hours, the audio playing proportion is 27.8%, and the total playing time of the video file is 330 hours, the video playing proportion is 45.8%, and the video playing proportion is greater than the audio playing proportion, the category of the application program is set as the video type.

In other embodiments, the electronic device sends a category query request for the application program to the server, and the server determines the audio playing proportion and the video playing proportion according to the operation behavior data corresponding to the application program, which is obtained in advance, and determines the category of the application program according to a size relationship between the audio playing proportion and the video playing proportion, which may specifically refer to the foregoing description.

After the video type of the target video is determined, whether the video type is a preset video type is judged, wherein the preset video type is a type which is preset and needs to reduce audio playing delay, and can be set by a user according to requirements, for example, the preset video type can be a game type, a video type and the like. If the video type is a preset video type, S303 is performed.

S303: and reducing the upper limit times of data retransmission between the electronic equipment and the wireless audio playing equipment.

S304: and sending the audio data to the wireless audio playing equipment according to the reduced upper limit times of data retransmission, and instructing the wireless audio playing equipment to play the audio data.

Therefore, in the embodiment of the present application, the transmission of audio data in a video being played can be reduced by the upper limit number of data retransmission, so as to reduce the delay of audio data, for example, a video includes a plurality of video frames and a segment of voice, where the voice is "i am a chinese and i am a country", the voice is broken into a plurality of data packets "i am", and if "i am" is not successfully transmitted, that is, the wireless audio playing device does not receive, in the prior art, an electronic device will transmit once again after the failure of this transmission of "i am", until the transmission is successful or the number of transmissions reaches the upper limit number of data retransmission, whereas in the method provided in the embodiment of the present application, the electronic device will transmit once again after the failure of this transmission of "i am", regardless of whether this transmission is successful or not, the method does not repeatedly send the 'my yes', or directly abandons sending the 'my yes' after the failure of sending the 'my yes' this time, but continues to send the 'Chinese' after the 'my yes'. Therefore, although the user cannot hear the 'my yes' because the 'my yes' is not successfully transmitted, if the 'Chinese', 'I love', 'My country' can be transmitted successfully, the user can quickly hear the 'Chinese' and the subsequent voice, and the pictures corresponding to the voice can be ensured to be synchronous when the 'Chinese', 'I love', 'My country' are played.

It should be noted that, for the parts not described in detail in the above steps, reference may be made to the foregoing embodiments, and details are not described herein again.

In addition, considering that some audio is not video, but the real-time performance of the audio itself is high, if there is a high delay, the user experience is too low, so to overcome this drawback, please refer to fig. 4, which shows a data transmission method, including: s401 to S405.

S401: when the electronic equipment is connected with the wireless audio playing equipment, whether the electronic equipment receives a playing request of audio data or not is detected.

S402: and determining the real-time performance level corresponding to the audio data.

And if the playing request of the audio data is received, determining the real-time level of the audio data. In one embodiment, an identifier of an application program corresponding to the audio data is determined, and then a real-time level of the audio data is determined according to the identifier of the application program. Specifically, an identifier of an application program that sends the play request of the audio data is determined, and in determining a type of the application program corresponding to the identifier of the application program, reference may be made to the above-described embodiment.

Then, the real-time level corresponding to the audio data is determined according to the type of the application program. Specifically, the real-time performance level corresponding to the type of the application program is stored in the electronic device, as shown in table 2 below:

TABLE 2

Identification of applications	Categories of applications	Level of real-time
			Apk1	Game machine	J1
Apk2	Video	J2
			Apk3	Audio frequency	J3
Apk4	Social interaction	J1

According to the corresponding relation, the real-time performance level corresponding to the audio data can be determined. For example, if the identifier of the application program corresponding to the audio data is Apk4, the corresponding category is social, and the corresponding real-time level is J1. Of these, J1 is ranked the highest, and next, J2 and J3 decrease in order.

S403: and judging whether the real-time level of the audio data meets a preset level or not.

The preset level is a preset real-time level corresponding to the type of audio playing delay reduction required, and can be set by a user according to requirements. For example, the preset level is J2 and above. If the real-time level corresponding to the audio data is J1, the real-time level of the audio data satisfies a preset level, and then S404 is performed.

If the real-time level corresponding to the audio data is J3, and the real-time level of the audio data does not meet the preset level, the method may be ended, or the step of S302 may be executed, so that, if a certain application is a newly installed application and the real-time level is not set, it may be further determined whether the upper limit number of data retransmission between the electronic device and the wireless audio playing device needs to be reduced through the operation of S302.

Alternatively, S302 may be executed before step S402 is executed, and S402 may be executed when the audio data belongs to audio data played in correspondence with the image data as a result of the determination at S302.

S405: and sending the audio data to the wireless audio playing equipment according to the reduced upper limit times of data retransmission, and instructing the wireless audio playing equipment to play the audio data.

The determination of the real-time level of the audio data may be performed after the determination result of S302 is yes, or the determination of the real-time level may be performed before S302 is performed.

In view of the fact that when the channel quality of a channel for transmitting data between an electronic device and the wireless audio playing device is different, the number of retransmissions may be different, for example, when the channel quality is good, the number of retransmissions is large, and when the channel quality is poor, the number of retransmissions is small, and therefore, the reduction range of the upper limit number of data retransmissions between the electronic device and the wireless audio playing device may be adjusted based on the channel quality, specifically, referring to fig. 5, a data transmission method provided by an embodiment of the present application is shown, and specifically, the method includes: s501 to S504.

S501: when the electronic equipment is connected with the wireless audio playing equipment, whether the electronic equipment receives a playing request of audio data or not is detected.

S502: and acquiring the channel quality of a channel for transmitting data between the electronic equipment and the wireless audio playing equipment.

The channel quality may be an error vector magnitude of a channel, a number of access points, a signal strength, and the like. An Error Vector Magnitude (EVM) is a Vector difference between an ideal Error-free reference signal and an actually transmitted signal at a given time, and is used for measuring an amplitude Error and a phase Error of a modulated signal, and the EVM specifically indicates a proximity degree of an IQ component generated when a receiving terminal demodulates the signal and an ideal signal component, and is an index for considering the quality of the modulated signal. The smaller the EVM, the better the channel quality of the channel. The number of the access points can also acquire the access points on each channel when the channels are scanned, so that the number of the access points on each channel can be determined, and the larger the number of the access points is, the worse the channel quality is, and vice versa, the better the channel quality is. Similarly, the signal strength can also be obtained during channel scanning, and the higher the signal strength is, the higher the channel quality is, and vice versa, the lower the channel quality is.

When entering a new network environment, the mobile terminal scans a plurality of supported channels according to a preset channel scanning sequence, and in the scanning process of each channel, a wireless access point on the channel can be obtained, so that the channel where each wireless access point is located can be determined. Therefore, the channel where the connected wireless audio playing equipment is located can be determined, and the error vector magnitude corresponding to the channel is further obtained.

S503: and reducing the upper limit times of data retransmission between the electronic equipment and the wireless audio playing equipment according to the channel quality.

The channel quality is inversely proportional to the reduction amplitude of the upper limit number of data retransmission between the electronic device and the wireless audio playing device, that is, the higher the channel quality is, the smaller the reduction amplitude is, the smaller the channel quality is, the larger the reduction amplitude is, therefore, when the channel quality is higher, the speed of data transmission is faster, the time consumed by retransmission is shorter, in order to ensure the integrity of data, multiple retransmission times can be considered, that is, the reduction amplitude of the upper limit number of data retransmission is smaller, whereas if the channel quality is poorer, the speed of data transmission is likely to be lower, in order to ensure the timeliness of data transmission, the reduction amplitude of the upper limit number of data retransmission is larger, that is, the upper limit number of initial data retransmission is 3, if the number of times needs to be reduced, and if the channel quality is poorer, the upper limit number of times is reduced to 1, if the channel quality is good, the upper limit number is reduced to 2.

S504: and sending the audio data to the wireless audio playing equipment according to the reduced upper limit times of data retransmission, and instructing the wireless audio playing equipment to play the audio data.

It should be noted that, the above-mentioned S502 and S503 are specific embodiments of how to reduce the upper limit number of times of data retransmission between the electronic device and the wireless audio playing device, and they can be regarded as specific embodiments of S202 in fig. 2, S303 in fig. 3, and S404 in fig. 4, which can be combined with the above-mentioned embodiments.
