Wherein the first information and the second information are messages in an existing protocol. For example: the first information is information or a request for acquiring 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 set default field for indicating that the field for supporting the audio data preloading function is a second set default field. For example: the existing transmission protocol is improved, a set default field in a transmission message in the existing transmission protocol is set as a field for inquiring whether the audio data preloading function is supported, and a set default field in a transmission message in the existing transmission protocol is set 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 used communication protocol is an Audio/Video Remote Control protocol (AVRCP), a default event identification field in the acquisition capability message is selected, the event identification field is used for inquiring whether a field supporting an Audio data preloading function is used, the default event identification field is selected in the corresponding response acquisition capability message, and the event identification field is used for indicating whether the field supporting the Audio data preloading function is used, for example: when the value of this field is 1, it indicates that the audio data preloading function is supported, and when the value of this field is 0, it indicates that the audio data preloading function is not supported.

The 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, the method further includes: step S11 ″, receiving preloaded interface information from the playback terminal, where the preloaded interface information includes an interface identifier, or the preloaded interface information includes an interface identifier and also includes corresponding interface capacity and/or interface availability status. And determining at least one interface identifier according to the pre-loading interface information, and determining the one-to-one correspondence relationship 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, the sending at least one target audio data to the playback terminal through the short-range wireless connection includes: sequentially sending corresponding target audio data according to a set sorting rule of the at least one interface identifier; or respectively sending combined data, wherein the combined data comprises an interface identifier and target audio data corresponding to the interface identifier. The set 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, including: 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 below.
The interface identification is incremented by a natural number in the form of an index (index) or handle (handle).
In step S11 ″, the preloaded interface information includes an interface identifier, which corresponds to a 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 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 values are generally positive integers, and for example, when the number of Interface identifiers is 5, the index values are 0, 1, 2, 3, and 4, respectively.
The preloaded interface information comprises interface identifications and also comprises corresponding interface capacities and/or interface available states, wherein the interface capacities and the interface available states corresponding to different interface identifications are different. For example: when the number of the interface identifiers is 5, the interface identifier value, the interface capacity and the interface available state 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 following steps:
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 is provided with 2 target pre-loading audio data, the capacity of the first target pre-loading audio data is 4MB, and the capacity of the second target pre-loading audio data is 10 MB. 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.
Or, the mobile terminal has 2 target pre-load audio data, the capacity of the first target pre-load audio data is 4MB, and the capacity of the second target pre-load audio data is 20 MB. 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, the information of setting the interface index (Set Pre-Streaming index-x) for preloading audio data is adopted, and the information comprises the index value of the determined interface identifier. And 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 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, the sending at least one target audio data to the playback terminal through the short-range wireless connection includes: and sequentially sending corresponding target audio data according to the set ordering rule of the at least one interface identifier.
For example: the interface identifiers contained in the preloaded interface information are 3, which are respectively 0, 1 and 2. The mobile terminal selects two interface identifiers, namely a first interface identifier and a third interface identifier, and the corresponding values are 0 and 2 respectively. The playing terminal learns that the interface identifiers selected by the mobile terminal are the first interface identifier and the third interface identifier, and the corresponding values are 0 and 2 respectively. The mobile terminal determines that the first interface identification corresponds to the first audio data and the third interface identification corresponds to the second audio data. When the two audio data are transmitted, the corresponding audio data are respectively transmitted according to the sequence from the small interface identifier to the large interface identifier. After the first audio data is transmitted, the second audio data is transmitted. After the playing terminal receives the two audio data, the first received audio data is determined to correspond 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, the sending at least one target audio data to the playback terminal through the short-range wireless connection includes: respectively sending an interface identifier and target audio data corresponding to the interface identifier.
For example: the interface identifiers contained in the preloaded interface information are 3, which are respectively 0, 1 and 2. The mobile terminal selects two interface identifiers, namely a first interface identifier and a third interface identifier, and the corresponding values are 0 and 2 respectively. The playing terminal learns that the interface identifiers selected by the mobile terminal are the first interface identifier and the third interface identifier, and the corresponding values are 0 and 2 respectively. The mobile terminal determines that the first interface identification corresponds to the first audio data and the third interface identification corresponds to the second audio data. When the two audio data are transmitted, the first combined data is transmitted, where the first combined data is the first interface identifier 0 and the first audio data corresponding to the first interface identifier, the transmission process may be referred to as an index value x for Pre-loading the audio data and audio data transmission (Pre-Streaming index-x data transmission), and after the broadcast terminal successfully receives the first combined data, the broadcast terminal transmits a corresponding notification to the mobile terminal, where the notification may be referred to as an index value x for Pre-loading the audio data and an audio data acknowledgement notification (Pre-Streaming index-x data ready notification). Similarly, second combined data is sent, where the second combined data is third interface identifier 2 and second audio data corresponding to the third interface identifier.
The sending of the instruction to play the target audio data in step S15 includes: and sending an instruction for playing the target audio data, wherein the instruction carries an interface identifier corresponding to the target audio data, for example, the name of the instruction is a playing instruction (Play Pre-Streaming index-x) corresponding to the preloaded index value x, and after receiving the playing instruction and completing playing, the playing terminal returns a playing completion confirmation message to the mobile terminal.

For example: displayed in a dialog box, the dialog box includes a first option and a second option. After receiving the confirmation signal that the user selects to use the pre-loaded audio mode, the mobile terminal executes the execution steps from step S13 to step S15, and after receiving the confirmation signal that the user selects not to use the pre-loaded audio mode, the mobile terminal adopts the mode of transmitting audio data in real time and controlling the playing terminal to play in the prior art.

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 using the second channel. For example: this second channel is the bluetooth Audio Distribution Profile (AADP) channel. The second channel supports synchronous playing of the sound effect of button touch control on the mobile terminal.
In this embodiment, in order to prevent interference of two audio data transmission modes, a first channel is specially configured for transmitting target audio data, so as to be clearly distinguished from a second channel for transmitting real-time audio data to be played.
