And sending the 4 target audio data to the playing terminal in advance, so that the playing terminal loads the 4 target audio data. When the game application is run on the mobile terminal, the playing terminal is controlled to play the audio synchronously, and when the first target audio data needs to be played, an instruction for playing the first target audio data is sent to the playing terminal, and the first target audio data does not need to be transmitted, so that the playing terminal directly plays the loaded first target audio data; when the second target audio data is required to be played, sending an instruction for playing the second target audio data to the playing terminal, and directly playing the loaded second target audio data by the playing terminal without transmitting the second target audio data; and similarly, carrying out the homomorphism processing on other target audio data.

For example: in the prior art, after the optimized audio transmission software and a new audio coding algorithm supporting low delay are used, the audio delay is more than 100 milliseconds, and the transmission delay can be reduced from a hundred millisecond level to a ten millisecond level by using the method.

Wherein the first information and the second information are messages in an existing protocol. For example: the first information is information or a request to obtain a capability status (get capabilities status), and the second information is a preloaded data stream response, which may be an Event such as a preloaded data stream Event (Pre-Streaming Event).
The field for inquiring whether the audio data preloading function is supported is a first setting default field, and the field for indicating that the audio data preloading function is supported is a second setting default field. For example: the method comprises the steps of improving an existing transmission protocol, setting a default setting field in a transmission message in the existing transmission protocol as a field for inquiring whether the audio data preloading function is supported or not, and setting the default setting field in the transmission message in the existing transmission protocol as a field for indicating that the audio data preloading function is supported.
For example: the short-distance wireless communication mode between the mobile terminal and the playing terminal is a bluetooth communication mode, the communication protocol used is Audio/video remote control protocol (Audio/Video Remote Control Profile, AVRCP), a default event identification field in the acquisition capability message is selected, the event identification field is used for inquiring whether a field of the Audio data preloading function is supported, a default event identification field is selected in the corresponding response acquisition capability message, and the event identification field is used for indicating whether the Audio data preloading function is supported, for example: supporting the audio data preloading function is indicated when the value of this field is 1, and not supporting the audio data preloading function when the value of this field is 0.

For example: the AT command is an "at+brsf" command for requesting AG characteristics, an "at+cind" command for acquiring the partner characteristic support case, or the like.
Or, customizing a new transmission protocol, wherein the first information is a query message in the custom protocol, and the second information is an indication message in the custom protocol. For example: the Bluetooth BLE control protocol or the SPP serial data transmission protocol is customized.
An embodiment of the present disclosure provides an audio playing control method, where the method includes the method in the previous embodiment, and in the method, between step S11 and step S12, further includes: step S11', receiving preloaded interface information from the playing terminal, wherein the preloaded interface information comprises an interface identifier, or the preloaded interface information comprises the interface identifier and also comprises corresponding interface capacity and/or interface available state. And determining at least one interface identifier according to the preloaded interface information, and determining a one-to-one correspondence between the at least one interface identifier and the at least one target audio data. And sending the determined at least one interface identifier to the playing terminal.
In step S12, at least one target audio data is sent to the playing terminal through the short-distance wireless connection, including: sequentially sending corresponding target audio data according to the set ordering rule of the at least one interface identifier; or respectively transmitting combined data, wherein the combined data comprises an interface identifier and target audio data corresponding to the interface identifier. Wherein, the setting of the ordering rule refers to the ordering of the interface identifiers from small to large or from large to small.
In step S15, sending an instruction to play the target audio data includes: and sending an instruction for playing the target audio data, wherein the instruction carries an interface identifier corresponding to the target audio data.
The details of this embodiment are described in detail below.
The interface identifier is incremented by a natural number in the form of an index (index) or handle (handle).
In step S11", the preloaded interface information includes the interface identifier, corresponding to the case where the interface capacity of each interface is the same by default, the interface capacities are all fixed default capacities (e.g., 5M), and the interfaces are all in default available states. The preloaded interface information is interface index information (notify Pre-Streaming Interface index) for notifying the preloaded data stream, and the index value is generally a positive integer, for example, when the number of interface identifiers is 5, the index values are respectively 0, 1, 2, 3 and 4.
The preloaded interface information comprises interface identifiers, corresponding interface capacities and/or interface available states, and corresponds to the situation that the interface capacities and the interface available states corresponding to different interface identifiers are different. For example: when the number of the interface identifiers is 5, the interface identifier values, the interface capacities and the interface availability states included in the preloaded interface information are respectively as follows: 0,10M, available; 1,8M, available; 2,6M, available; 3,5M, available; 4,4M, available.
And when at least one interface identifier is determined according to the preloading interface information, determining at least one interface identifier according to the preloading interface information and the capacity of the target preloading audio data.
Examples are as follows: the number of the interface identifiers is 3, and the preloading interface information comprises:
the interface identifier of the first interface is 0, the capacity is 5MB, and the interface available state is available.
The interface identifier of the second interface is 1, the capacity is 10MB, and the interface available state is available.
The interface identifier of the third interface is 2, the capacity is 15MB, and the interface available state is unavailable.
The mobile terminal has 2 target pre-load audio data, the first target pre-load audio data has a capacity of 4MB, and the second target pre-load audio data has a capacity of 10MB. The mobile terminal selects a first interface and a second interface and determines that the first interface identification corresponds to the first target preloaded audio data and the second interface identification corresponds to the second target preloaded audio data.
Alternatively, the mobile terminal has 2 target preloaded audio data, the first target preloaded audio data having a capacity of 4MB and the second target preloaded audio data having a capacity of 20MB. The mobile terminal selects the first interface and determines that the first interface identification corresponds to the first target preloaded audio data.
When the mobile terminal sends the determined at least one interface identifier to the playing terminal, information of interface index (Set Pre-Streaming index-x) for preloading audio data is adopted, and the information contains an index value for determining the interface identifier. After receiving the information for setting the interface index for the preloaded audio data, the playing terminal acquires the interfaces selected by the mobile terminal and used for storing the target preloaded audio data, reserves the interface identifiers of the interfaces, and returns response information to the mobile terminal.
In step S12, at least one target audio data is sent to the playing terminal through the short-distance wireless connection, including: and sequentially sending corresponding target audio data according to the set ordering rule of the at least one interface identifier.
For example: the number of interface identifiers contained in the preloaded interface information is 3, namely 0,1 and 2 respectively. The mobile terminal selects two interface identifiers, namely a first interface identifier and a third interface identifier, and the corresponding values are respectively 0 and 2. The playing terminal knows that the interface identifier selected by the mobile terminal is a first interface identifier and a third interface identifier, and the corresponding values are respectively 0 and 2. The mobile terminal determines that the first interface identifier corresponds to the first audio data and the third interface identifier corresponds to the second audio data. When the two audio data are transmitted, each corresponding audio data are respectively transmitted according to the sequence from small to large of the interface identification. After the first audio data is transmitted, the second audio data is transmitted. After receiving the two audio data, the playing terminal determines that the first received audio data corresponds to the interface identifier 0 according to the sequence from small to large of the interface identifiers, and the second received audio data corresponds to the interface identifier 2.
Or, in step S12, at least one target audio data is sent to the playing terminal through the short-distance wireless connection, including: and respectively sending an interface identifier and target audio data corresponding to the interface identifier.
For example: the number of interface identifiers contained in the preloaded interface information is 3, namely 0,1 and 2 respectively. The mobile terminal selects two interface identifiers, namely a first interface identifier and a third interface identifier, and the corresponding values are respectively 0 and 2. The playing terminal knows that the interface identifier selected by the mobile terminal is a first interface identifier and a third interface identifier, and the corresponding values are respectively 0 and 2. The mobile terminal determines that the first interface identifier corresponds to the first audio data and the third interface identifier corresponds to the second audio data. When the two audio data are transmitted, the first combined data are the first interface identifier 0 and the first audio data corresponding to the first interface identifier, the transmitting process can be called as an index value x for preloading the audio data and audio data transmission (Pre-Streaming index-x data transmission), and after the playing terminal receives the audio data successfully, a corresponding notification is transmitted to the mobile terminal, and the notification can be called as an index value x for preloading the audio data and audio data confirmation notification (Pre-Streaming index-x data ready notify). And similarly, sending second combined data, wherein the second combined data is the third interface identifier 2 and second audio data corresponding to the third interface identifier.
In step S15, an instruction to play the target audio data is sent, including: and sending an indication of playing the target audio data, wherein the indication carries an interface identifier corresponding to the target audio data, for example, the indication is named as a playing indication (Play Pre-Streaming index-x) corresponding to the preloading index value x, and after receiving the playing indication and completing playing, the playing terminal returns playing completion confirmation information to the mobile terminal.

For example: the method comprises the steps of displaying in a dialog box, and including a first option and a second option on the dialog box. After receiving the confirmation signal of the user selecting to use the pre-loading audio mode, the mobile terminal executes the execution steps of the steps S13 to S15, and after receiving the confirmation signal of the user selecting not to use the pre-loading audio mode, the mobile terminal adopts the mode of transmitting audio data in real time and controlling the playing terminal to play.

When the audio data to be played is transmitted through the short-distance wireless connection in step S16, the audio data to be played is not the target audio data, a second channel is established, and the audio data to be played is transmitted by using the second channel. For example: the second channel is a bluetooth audio transport model protocol (Advanced Audio Distribution Profile, AADP) channel. The second channel supports synchronous playing of sound effects of key touch control on the mobile terminal.
In this embodiment, in order to prevent interference of two audio data transmission modes, a first channel is specifically set for transmitting target audio data, so as to be clearly distinguished from a second channel for transmitting real-time audio data to be played.
