Fig. 2 schematically shows a flow chart of a method of playing audio data according to an embodiment of the present application. As shown in fig. 2, the method is applied to a bluetooth device, and includes:
s101, when a first audio data stream transmitted by a target device in real time is received, playing a first part of target audio data based on the received first audio data stream, wherein the target audio data comprises the first part and a second part.
It should be noted that, in the present application, the target device is not specifically limited, and may be, for example, an intelligent device or a server. The mobile terminal may be a PC (Personal Computer), a smart phone, a tablet PC, an e-book reader, an MP3(Moving Picture Experts Group audio Layer III) player for playing audio data, an MP4(Moving Picture Experts Group audio Layer IV) player for playing audio data, a portable Computer, and other mobile terminal devices with display functions, and so on.
Further, the bluetooth device is not specifically limited in this application, and may be, for example, various bluetooth headsets, bluetooth speakers, and the like. Similarly, the number of bluetooth devices is not specifically limited in this application, and may be, for example, 2 or more.
With the development of wireless communication and near field technologies, more and more scenes exist in which bluetooth is used by mobile terminal devices, and data transmission can be performed between mobile terminals through bluetooth. Meanwhile, the mobile terminal and the bluetooth device are connected in a matching manner in more and more scenes, for example, a user can take a bluetooth headset to answer a call more conveniently when driving, or a bluetooth sound box is used at home to play audio and video, and the like. In the related art, when the mobile terminal and the bluetooth device are connected in a pairing manner, the bluetooth device receives an audio data stream sent by the mobile terminal in real time and plays music according to the received data stream.
For example, in an office environment, most users prefer to work while listening to music while wearing a bluetooth headset. Meanwhile, the user can keep wearing the Bluetooth headset, the user needs to briefly go to a toilet to wash the face or cut tea in a tea room to pour water, and the Bluetooth headset gradually leaves the effective connection range of the mobile terminal under the condition that the place is far away, so that the Bluetooth headset is interrupted, music cannot be continuously played, and user experience is affected. Or, when the user wears the bluetooth headset to listen to music, the user just passes through an area with large interference, which also causes the mobile terminal and the bluetooth headset to be disconnected temporarily due to the interference. And then the music is paused, which affects the user experience.
Therefore, in order to solve the problems in the related art, in the present application, first, when a first audio data stream transmitted by a target device in real time is received, a first portion of target audio data is played based on the received first audio data stream. It should be noted that the present application does not specifically limit the target audio data. That is, the target audio data may be music or audio data in video. In addition, the target audio data should include two parts, i.e., a first part and a second part. The first portion and the second portion are not specifically limited in the present application, that is, the first portion may be audio data in any range of the target audio data, and the second portion may also be audio data in any range of the target audio data.
S102, sending a transmission request to the target device, wherein the transmission request is used for obtaining the residual audio data stream aiming at the target audio data, and the residual audio data stream corresponds to the second part of the target audio data.
In this application, the following description will be given taking a target device as a mobile terminal as an example: after obtaining the first audio data stream of the target device, a transmission request for obtaining a remaining audio data stream for the target audio data may be sent to the target device. Wherein the remaining audio data stream is an audio data stream corresponding to the second portion of the target audio data. It can be understood that, in order to avoid the above-mentioned disadvantage of the related art that the bluetooth device cannot continue playing music when the mobile terminal is disconnected from the bluetooth device. In the application, when the Bluetooth device starts to play music, the mobile terminal is requested to send all the residual data streams of the music to the mobile terminal. So that the music can be played continuously according to the data stream received in advance when the remaining data stream of the music cannot be received continuously.
It should be noted that, the present application does not specifically limit the time when the bluetooth device sends the transmission request to the target device, and for example, the transmission request may be sent to the target device after a preset time for playing the target audio data is detected. It may also be that a transmission request or the like is sent to the target device after detecting that the current communication status is below a preset condition.
In yet another embodiment of the present application, after playing the first portion of the target audio data, the following steps may be further implemented:
detecting electric quantity information of target equipment;
and when the power information of the target device is determined to be lower than the power threshold value, sending a transmission request to the target device.
In this application, after the first part of the target audio data is played, in order to avoid the above-mentioned disadvantage that the bluetooth device cannot continue playing music when the mobile terminal is disconnected from the bluetooth device. The method and the device can detect the electric quantity information of the target device at first to avoid the defect that the target device cannot continue playing music when the target device is powered off due to insufficient residual electric quantity.
It is understood that, when it is determined that the power information of the target device is lower than the preset power threshold, a transmission request for obtaining the remaining audio data stream for the target audio data may be sent to the target device. The electric quantity threshold is not specifically limited in the present application, and may be, for example, 10%, or 5%.
In addition, the power information of the target device is also not specifically limited, and may be, for example, remaining power information of the target device or current power information of the target device.
S103, when the residual audio data stream of the target audio data is acquired, storing the residual audio data stream into a local cache.
Further, in the present application, after the transmission request is sent to the target device, the corresponding remaining audio data stream may be ready to be received. And when receiving the residual audio data stream, the residual audio data stream can be stored in a local cache.
And S104, when the occurrence of the interrupt event is detected, playing the second part of the target audio data by using the residual audio data stream, wherein the interrupt event is an event of communication disconnection with the target equipment.
Further, when the bluetooth device detects that the communication disconnection with the target device currently occurs, it can be determined that the remaining part of the target audio data cannot be played continuously currently. In order not to affect the listening experience of the user, the method and the device can continue to play the second part of the target audio data by using the residual audio data stream stored in the local cache.
It should be noted that, in the present application, the bluetooth device continues to play the second part of the target audio data by using the remaining audio data stream. If a reconnection to the target device is detected, the remaining audio data stream may continue to be utilized to play the second portion of the target audio data. Playback of the second portion of the target audio data may also be accomplished via an audio data stream communicated to the target device.
According to the method and device for playing the audio data, when a first audio data stream sent by a target device in real time is received, a first part of the target audio data is played, a transmission request for obtaining a residual audio data stream aiming at the target audio data is sent to the target device, when the residual audio data stream of the target audio data is obtained, the residual audio data stream is stored in a local cache, and when an interrupt event of communication disconnection with the target device is detected, a second part of the target audio data is played by using the residual audio data stream. By applying the technical scheme of the application, when the Bluetooth equipment is connected with the mobile phone and plays music, all the residual data of the music can be received and stored in the cache in advance, so that when the mobile phone is disconnected with the Bluetooth equipment, the music can be continuously played according to the residual data stored in the cache. And then can avoid the problem that exists in the correlation technique when mobile terminal and bluetooth equipment disconnection, can't continue to play audio data.
In one possible implementation manner of the present application, after S103 (when the remaining audio data stream of the target audio data is acquired, the remaining audio data stream is stored in the local cache), the following steps may be further implemented:
and when the interruption event is not detected, receiving a second audio data stream transmitted by the target device in real time, and playing a second part of the target audio data.
It can be understood that, if the bluetooth device does not detect the occurrence of the interrupt event of the communication disconnection with the target device in the process of playing the target audio data this time, the remaining audio data stream stored in its own buffer may not be used. But the playing of the second part of the target audio data is realized by continuing the real-time reception of the second audio data stream sent by the target device.
In yet another possible implementation manner of the present application, in S103 (when the occurrence of the interruption event is detected, the remaining audio data stream is utilized to play the second part of the target audio data), the following steps may be further implemented:
when an interruption event is detected, determining a first playing progress corresponding to target audio data based on a first audio data stream;
selecting a third audio data stream based on the first playing progress corresponding to the target audio data, wherein the third audio data stream is a data stream generated based on the residual audio data stream;
playing a second portion of the target audio data using the third audio data stream.
Furthermore, when the bluetooth device detects that the current interrupt event of communication disconnection with the target device occurs, the remaining audio data stream is reused to play the second part of the target audio data, so as to ensure the consistency of music playing. The method and the device need to determine a first playing progress when the Bluetooth device plays the target audio data when an interrupt event occurs. Further, the method and the device can determine a first playing progress corresponding to the target audio data based on the received first audio data stream.
In addition, after the first playing progress is determined, the third audio data stream corresponding to the remaining playing part can be further determined. And may play a second portion of the target audio data based on the third audio data stream. It should be noted that the third audio stream is included in the remaining audio stream. That is, the third audio stream may be the entire data stream of the remaining audio stream, or may be a part of the remaining audio stream.
For example, the music corresponding to the target audio data is "happy birthday", and the playing time of "happy birthday" is 2 minutes. In the application, when it is detected that a disconnection event occurs currently, it may be determined that the first playing progress corresponding to the currently played target audio data is fifty percent (that is, a part of "happy birthday" played currently in the previous minute) based on the received first audio data stream. Further, based on the first playing schedule, selecting an audio data stream (i.e. a third audio data stream) with a time period range of 1 minute 01 seconds to 2 minutes corresponding to "happy birthday" from the remaining audio data streams. And based on the third audio data stream, continuing to play the part of the next minute of 'happy birthday'.
Alternatively, music corresponding to the target audio data is "happy birthday", and the data size of "happy birthday" is 20M. In the present application, when it is detected that a disconnection event currently occurs, it may be determined that the currently received first audio data stream is 10M based on the already received first audio data stream, and thus it may be determined that the corresponding first playing progress is fifty percent (that is, the first half of "happy birthday" is currently played). Further, based on the first playing schedule, selecting an audio data stream (i.e. a third audio data stream) with a playing time of 10M-20M corresponding to "happy birthday" from the remaining audio data streams. And based on the third audio data stream, the second half of the happy birthday is played continuously.
In another possible implementation manner of the present application, after playing the second portion of the target audio data by using the third audio data stream, the following steps may be further implemented:
when a connection event is detected to occur, determining a second playing progress corresponding to a second part of the playing target audio data by using a third audio data stream, wherein the connection break event is an event in communication connection with the target equipment;
when the second part of the target audio data is determined to be not completely played according to the second playing progress, a fourth audio data stream sent by the target device in real time is obtained, and the fourth audio data stream is a data stream generated according to the second playing progress;
based on the fourth audio data stream, a second portion of the target audio data is played.
Further, when the disconnection event is detected, and when the event of the communication connection between the bluetooth device and the target device is detected after the third audio data stream is used for playing the second part of the target audio data, the audio data stream obtained by the communication with the target device again can be selected to be used for playing the second part of the target audio data.
Wherein, the consistency of playing music is ensured. The second playing progress of the bluetooth device when playing the second part needs to be determined when the connection event occurs. Further, the present application may determine a second playing progress corresponding to the target audio data based on the generated third audio data stream. And receiving a fourth audio data stream sent by the target device after the second playing progress is determined. And playing the second part of the target audio data by using the fourth audio data stream.
It can be understood that, in the present application, after the second playing progress is determined, when it is determined that the playing of the second portion of the target audio data is not completed according to the second playing progress, the fourth audio data stream sent by the target device is obtained. In other words, when it is detected that the playing of the second portion of the target audio data is completed, it is determined that the playing of the target audio data is completed. The playback of the next audio data can be started.
For example, the music corresponding to the target audio data is "happy birthday", and the playing time of "happy birthday" is 2 minutes. When detecting that a disconnection event occurs currently, the present application may determine, based on the already received first audio data stream, that the first playing progress corresponding to the currently playing target audio data is fifty percent. And a third audio data stream is selected from the remaining audio data streams to continue playing the part of the next minute of Happy birthday. Further, when the bluetooth device detects that a connection event occurs, it may be determined that the second playing progress corresponding to the target audio data is seventy-five percent (i.e., playing to "happy birthday" 1 minute 30 seconds) based on the third audio data stream currently being played. And informing the mobile terminal of the second playing progress so that the mobile terminal transmits an audio data stream (namely, a fourth audio data stream) corresponding to 1 minute 31 seconds-2 minutes of Happy birthday to the Bluetooth equipment. And based on the fourth audio data stream, the rest of the happy birthday is played continuously.
Further optionally, in another embodiment of the present application, after the present application S101 (when receiving the first audio data stream transmitted by the target device in real time, playing the first portion of the target audio data based on the received first audio data stream), a specific embodiment is further included, as shown in fig. 3, including:
s201, when a first audio data stream transmitted by a target device in real time is received, playing a first part of the target audio data based on the received first audio data stream.
S202, detecting the transmission quality of the first audio data stream.
S203, when the transmission quality of the first audio data stream is determined to be lower than the preset threshold value, a transmission request is sent to the target device.
In this application, after the first part of the target audio data is played, in order to avoid the above-mentioned disadvantage that the bluetooth device cannot continue playing music when the mobile terminal is disconnected from the bluetooth device. The method and the device can firstly detect the transmission quality of the first audio data stream so as to avoid the defect that the target device cannot continuously play music when the communication is disconnected due to poor communication quality.
It will be appreciated that upon determining that the transmission quality of the first audio data stream is below a preset threshold, a transmission request for obtaining the remaining audio data stream for the target audio data may be sent to the target device. It should be noted that, the preset threshold is not specifically limited in the present application, and may be, for example, 1M/s, or 2M/s.
In addition, the method for detecting the transmission quality of the first audio data stream is not specifically limited in the present application, and for example, the data may be detected by a bluetooth device, or the data may be sent to the bluetooth device after the target device detects the data.
Optionally, in the present application, the transmission efficiency corresponding to the bluetooth device may also be determined according to the configuration parameter of the bluetooth device, and whether a transmission request needs to be sent to the target device is selected according to the size of the transmission efficiency. Furthermore, the method and the device can obtain the Bluetooth stream bit rate and the Bluetooth chip type corresponding to the Bluetooth device. It can be understood that the higher the bit rate of the bluetooth stream and the bluetooth chip type of the bluetooth device are, the higher the transmission efficiency achieved in playing audio is.
Further optionally, whether a transmission request needs to be sent to the target device may be selected according to the RSSI signal value of the bluetooth device. Wherein, rssi (received Signal Strength indication) is represented as a Strength parameter of a received Signal of the mobile terminal. Its implementation is done after the backchannel baseband receive filter. For a bluetooth device, the RSSI value may reflect the strength of the bluetooth signal of the bluetooth device received by the corresponding mobile terminal. Further, for example, the RSSI value may be obtained by the following formula: RSSI is 10 × log P, and P represents the received signal power, and bluetooth transmits a broadcast, and the received signal power is affected by the distance. It will be appreciated that the lower the RSSI signal value of the bluetooth device, the higher the likelihood that it will send a transmission request to the target device.
S204, sending a transmission request to the target equipment.
And S205, when the residual audio data stream of the target audio data is acquired, storing the residual audio data stream into a local cache.
S206, when the interruption event is detected to occur, the residual audio data stream is utilized to play the second part of the target audio data.
S207, when the second part of the playing target audio data is determined to be finished, the residual audio data stream is cleared from the local cache.
Further, in the present application, after the second part of the target audio data is determined to be played, in order to save the memory in the bluetooth device, the remaining audio data stream corresponding to the target audio data may be removed from the local cache. Thereby avoiding affecting the quality of audio playing.
According to the method and device for playing the audio data, when a first audio data stream sent by a target device in real time is received, a first part of the target audio data is played, a transmission request for obtaining a residual audio data stream aiming at the target audio data is sent to the target device, when the residual audio data stream of the target audio data is obtained, the residual audio data stream is stored in a local cache, and when an interrupt event of communication disconnection with the target device is detected, a second part of the target audio data is played by using the residual audio data stream. By applying the technical scheme of the application, when the Bluetooth equipment is connected with the mobile phone and plays music, all the residual data of the music can be received and stored in the cache in advance, so that when the mobile phone is disconnected with the Bluetooth equipment, the music can be continuously played according to the residual data stored in the cache. And then can avoid the problem that exists in the correlation technique when mobile terminal and bluetooth equipment disconnection, can't continue to play audio data.
