The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
The User Equipment according to the embodiments of the present application may be an electronic device with communication capability, where the User Equipment may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various types of User Equipment (UE), mobile Station (MS), terminal device (terminal device), and so on.
The wireless earphone mentioned in the embodiment of the application is that the earphone wire in the middle is replaced by electric waves, and is connected to the transmitting end from the audio outlet of the audio playing device, and then the transmitting end sends the electric waves to the earphone of the receiving end, and the receiving end is equivalent to a radio. The wireless earphone may be classified into an infrared wireless earphone, a meter wave wireless earphone (FM frequency modulation earphone) and a decimeter wave wireless earphone (bluetooth earphone).
At present, when the audio delay between the wireless earphone and the user equipment is too large in the scenes of games, live broadcasting watching, video watching and the like, the situation that the pictures of the user equipment are inconsistent with the sounds heard by the user can be caused, and the experience of the user is seriously affected.
In view of the foregoing, embodiments of the present application provide a method and an apparatus for controlling a communication mode, and the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the communication mode control system 100 described in the present application includes: a user device 101 and a wireless headset 102, said user device 101 and said wireless headset 102 being capable of establishing a communication connection.
Referring to fig. 2, fig. 2 is a flow chart of a communication mode control method provided in an embodiment of the present application, which is applied to a user equipment, where the user equipment is in communication connection with a wireless headset; as shown in the figure, the present communication mode control method includes the following operations:
S201, the user equipment creates a fast track thread when detecting a low delay communication request for the wireless headset.
The user equipment may be a mobile phone, and whether there is a low latency requirement may be determined by identifying whether an application program at the mobile phone end invokes an AUDIO processing interface OpenSL ES, or whether an audio_output_flag_fast (AUDIO stream needs to be quickly OUTPUT to the AUDIO device) FLAG is set when an AUDIO track is created, or whether there is a low latency requirement may also be detected by using a whitelist of the mobile phone.
In order to better realize low delay, an application program with low delay requirement acquires the sampling rate of the user equipment before creating the audio track program, and then provides corresponding audio data according to the acquired sampling rate.
S202, the user equipment reduces the audio data buffer area through the fast track thread, and cancels the operations of resampling the target audio data and/or processing the sound effect of the target audio data.
The user equipment may be a mobile phone, and when the mobile phone detects that there is a low-delay application demand, the mobile phone may create a fast track thread through an audio module of the mobile phone, and the fast track thread reduces an audio data buffer area, cancels resampling of target audio data, cancels processing of sound effects of the target audio data, and reduces processing time of an audio stream at a mobile phone end, thereby reducing delay.
S203, when the user equipment detects that the audio codec selected by the user equipment is a first codec with non-low delay, the first codec is switched to a second codec with low delay.
For example, also taking a mobile phone as an example, when the audio module of the mobile phone recognizes a low-delay requirement, the requirement can be submitted to the bluetooth module of the mobile phone, and if the previously selected audio codec is not the low-delay audio codec, the bluetooth module of the mobile phone switches the previous audio codec to the low-delay audio codec.
S204, the user equipment sends a low-delay mode switching notification to the wireless earphone, wherein the low-delay mode switching notification is used for notifying the wireless earphone to switch the working mode of the wireless earphone to a low-delay mode.
The wireless earphone in the embodiment of the application may be a Bluetooth (Bluetooth) earphone, and may be connected to the user equipment through Bluetooth technology. Bluetooth is a wireless technology standard that enables short-range data exchange between fixed devices, mobile devices, and building personal area networks.
For example, taking a mobile phone and a bluetooth headset as an example, the mobile phone and the bluetooth headset establish communication connection through respective bluetooth modules, and then the bluetooth module at the mobile phone end sends a low-delay mode switching notification to the bluetooth headset to notify the bluetooth headset to enter a low-delay mode, wherein the bluetooth headset can be notified to enter the low-delay mode through a reconfiguration instruction reconfig or other customized commands.
In the embodiment of the application, when the user equipment detects a low-delay communication request aiming at the wireless earphone, a quick track thread is created; reducing an audio data buffer area through the fast track thread, and canceling the operations of resampling the target audio data and/or processing the sound effect of the target audio data; when detecting that the audio coder/decoder selected by the local terminal is a first coder/decoder with non-low delay, switching the first coder/decoder into a second coder/decoder with low delay; the method comprises the steps of sending a low-delay mode switching notification to the wireless earphone, wherein the low-delay mode switching notification is used for notifying the wireless earphone to switch the working mode of the wireless earphone into a low-delay mode, and therefore, user equipment reduces delay and simultaneously sends the low-delay mode switching notification to the wireless earphone, the user equipment and a mobile phone are optimized together, audio delay of the user equipment and the earphone is reduced, and user experience is improved.
In one possible example, the detecting a low-latency communication request for the wireless headset includes: detecting that an application program of a local terminal calls an audio processing interface OpenSL ES; or detecting that an application program of the local end creates a sound track program audioTrack to set a preset mark bit, wherein the preset mark bit is used for identifying that the audio stream needs to be quickly output to audio equipment; or detecting by means of a mobile phone application white list.
For example, taking a mobile phone as an example, when detecting that an application program in an application program installed in the mobile phone invokes an AUDIO processing interface OpenSL ES, or when detecting that an application program in the mobile phone creates an AUDIO track, an audio_output_flag_fast (AUDIO stream needs to be quickly OUTPUT to an AUDIO device) FLAG is set, or when detecting that an application program in an application whitelist of the mobile phone, determining that the mobile phone has a low-delay communication request for a wireless earphone, and creating a quick AUDIO track thread.
In order to better realize low delay, an application program with low delay requirement acquires the sampling rate of the user equipment before creating the audio track program, and then provides corresponding audio data according to the acquired sampling rate.
In this example, the user equipment side identifies the low-delay requirement scene, so that when the low-delay requirement scene is identified, the user equipment side switches to the low-delay mode to reduce the audio delay between the user equipment and the wireless earphone, and whether the application program calls the OpenSL ES or whether a preset mark bit for identifying that the audio stream needs to be quickly output to the audio equipment is set when the audioTrack is created or whether the application program and the wireless earphone are set or not is more convenient to identify the low-delay requirement of the local application program and the wireless earphone for audio data by a mode of a mobile phone application white list.
In one possible example, the sending a low-latency mode switch notification to the wireless headset includes: the low-delay mode switching notification is sent by a reconfiguration instruction reconfig.
For example, the user equipment may be a mobile phone, the wireless headset may be a bluetooth headset, the mobile phone and the bluetooth headset establish a communication connection through respective bluetooth modules, and the bluetooth module of the mobile phone may send a reconfiguration instruction reconfig to the bluetooth headset, where the instruction is used to notify the bluetooth headset end to enter a low-delay mode, so that the bluetooth headset end enters the low-delay mode after receiving the reconfiguration instruction reconfig sent by the mobile phone.
It can be seen that in this example, the low-delay mode switch notification is sent to the wireless headset by a reconfiguration instruction reconfig.
In one possible example, after the detecting the low-latency communication request for the wireless headset, the method further comprises: and when the audio data buffer area is detected to be smaller, adjusting the size of the Bluetooth transmission packet to be a preset size according to the size of the audio data buffer area.
For example, after detecting that there is a low-delay communication request for the wireless earphone, the ue detects whether the audio data buffer is reduced, and if so, according to the size of the reduced audio data buffer, the ue may correspondingly reduce the bluetooth data transmission packet, use packet data transmission, and increase the bluetooth interference-free capability.
Therefore, in this example, since the buffer size adjustment affects the anti-interference capability and the pull-apart capability, when entering the low-delay mode, the user can improve the anti-interference capability of bluetooth by adjusting the size of the bluetooth transmission packet, thereby improving the stability of bluetooth data transmission.
In one possible example, the method further comprises: determining the interference intensity of a scene where the local terminal is located; and adjusting the compression rate of the audio coding to be a preset compression rate according to the interference intensity so as to reduce the transmission code rate of Bluetooth to be a preset code rate.
For example, the wireless earphone may be a bluetooth earphone, the user equipment may be a mobile phone, the two are communicated through respective bluetooth modules, the user equipment determines the interference intensity of the scene where the local end is located, and adjusts the compression rate of the audio code to a corresponding compression rate according to different interference intensities, for example, when the user equipment is in a strong interference environment, the corresponding compression rate of the code is higher than that when the user equipment is in a weak interference environment, and the transmission code rate of bluetooth is reduced by increasing the compression rate of the code.
In this example, the compression rate of the audio code is adjusted according to the different interference intensities of the scene where the user equipment is located, so as to reduce the code rate of bluetooth transmission and improve the stability of bluetooth transmission.
Referring to fig. 3, fig. 3 is a flow chart of another communication mode control method provided in an embodiment of the present application, which is applied to a wireless headset, where the wireless headset is in communication connection with a user equipment; as shown in the figure, the present communication mode control method includes the following operations:
s301, the wireless earphone receives a low-delay mode switching notification sent by the user equipment.
Wherein the low-latency mode switch notification is sent by the user equipment after: creating a fast track thread upon detecting a low latency communication request for the wireless headset; the audio data buffer area is reduced through the fast track thread, and the operations of resampling the target audio data and/or processing the sound effect of the target audio data are canceled; and switching the first coder-decoder to a second coder-decoder with low delay when the selected audio coder-decoder at the local end is detected to be the first coder-decoder with non-low delay.
S302, the wireless earphone switches the working mode of the local terminal to a low-delay working mode.
The wireless earphone in the embodiment of the application may be a bluetooth earphone, and may be connected to the user equipment through bluetooth technology. Bluetooth is a wireless technology standard that enables short-range data exchange between fixed devices, mobile devices, and building personal area networks.
In the embodiment of the application, the wireless earphone receives a low-delay mode switching notification sent by user equipment; wherein the low-latency mode switch notification is sent by the user equipment after: creating a fast track thread upon detecting a low latency communication request for the wireless headset; the audio data buffer area is reduced through the fast track thread, and the operations of resampling the target audio data and/or processing the sound effect of the target audio data are canceled; when detecting that the audio coder/decoder selected by the local terminal is a first coder/decoder with non-low delay, switching the first coder/decoder into a second coder/decoder with low delay; the working mode of the local terminal is switched to be a low-delay working mode, and as seen in that the wireless earphone receives the low-delay mode switching notification from the user equipment, the working mode of the local terminal is switched to be the low-delay working mode, the user equipment terminal and the mobile phone terminal are optimized together, the audio delay of the user equipment terminal and the earphone terminal is reduced, and the user experience is improved.
In one possible example, the method further comprises: reducing an audio data buffer area of the earphone so that the buffer time is smaller than a first preset threshold value; the size of the target audio data decoded at a time is adjusted to a preset size to reduce the direct memory access (Direct Memory Access, DMA) switching time.
After receiving a notification sent by a user equipment end that the notification enters a low-delay mode, the wireless earphone end reduces the own audio data buffer area so as to reduce the buffer time, wherein the first preset threshold value can be 100 milliseconds, namely the buffer time is within a range of tens of milliseconds; the earphone end also adjusts the data size of the audio data decoded at one time so as to reduce the Direct Memory Access (DMA) switching time, thereby reducing the delay of the earphone end.
It can be seen that, in this example, by adjusting the size of the target audio data decoded at a time and by adjusting the audio data buffer area of the earphone end, the delay of the earphone end can be reduced.
In one possible example, the method further comprises: detecting the size of the cache data of the target audio data; and fine-tuning the playing speed of the earphone according to the size of the cache data of the target audio data.
For example, the earphone end may detect the size of the buffered data of the target audio data in the audio buffer area of the earphone end, and fine tune the earphone playing speed according to the size of the buffered data, for example, when the size of the buffered data is smaller, the earphone playing speed may be properly adjusted down, and when the buffered data is larger, the earphone playing speed may be properly adjusted up.
In this example, the playing speed of the earphone is finely adjusted according to the size of the buffered data of the target audio data, so that the playing speed of the earphone is adapted to the size of the buffered data, which is beneficial to maintaining the buffer balance.
In one possible example, the method further comprises: counting the stability of receiving the target audio data by the Bluetooth at the home terminal; and dynamically adjusting an audio data buffer area of the earphone according to the stability of the local Bluetooth for receiving the target audio data.
The wireless earphone can be a Bluetooth earphone and can be connected with the user equipment through Bluetooth technology.
For example, taking a bluetooth headset as an example, the bluetooth headset may count the stability of receiving the target audio data by the bluetooth headset, and dynamically adjust the size of the audio data buffer of the bluetooth headset according to the counted stability, for example, when the stability is weak, the size of the audio data buffer is appropriately adjusted to improve the stability under the interference environment.
In this example, the stability of the earphone in the interference environment is improved by dynamically adjusting the audio data buffer area of the earphone according to the stability of the counted local bluetooth receiving the target audio data.
Referring to fig. 4, fig. 4 is a flowchart of another communication mode control method according to an embodiment of the present application. As shown in the figure, the communication mode control method includes the steps of:
s401, the user equipment creates a fast track thread when detecting a low delay communication request for the wireless headset.
The user equipment may be a mobile phone, and whether there is a low latency requirement may be determined by identifying whether an application program at the mobile phone end invokes an AUDIO processing interface OpenSL ES, or whether an audio_output_flag_fast (AUDIO stream needs to be quickly OUTPUT to the AUDIO device) FLAG is set when an AUDIO track is created, or whether there is a low latency requirement may also be detected by using a whitelist of the mobile phone.
In order to better realize low delay, an application program with low delay requirement acquires the sampling rate of the user equipment before creating the audio track program, and then provides corresponding audio data according to the acquired sampling rate.
S402, the user equipment reduces the audio data buffer area through the fast track thread, and cancels the operations of resampling the target audio data and/or processing the sound effect of the target audio data.
The fast track thread reduces the audio data buffer area, cancels resampling of target audio data, cancels processing of sound effect of the target audio data, and reduces processing time of audio stream at the mobile phone end, thereby reducing delay.
S403, when the user equipment detects that the audio codec selected by the user equipment is a first codec with non-low delay, the first codec is switched to a second codec with low delay.
For example, taking a mobile phone as an example, when an audio module of the mobile phone recognizes a low-delay requirement, the requirement can be submitted to a bluetooth module of the mobile phone, and if the previously selected audio codec is not the low-delay audio codec, the bluetooth module of the mobile phone switches the previous audio codec to the low-delay audio codec.
S404, the user equipment sends a low-delay mode switching notification to the wireless earphone.
The low-delay mode switching notification is used for notifying the wireless earphone to switch the working mode of the wireless earphone into a low-delay mode.
S405, the wireless earphone receives a low-delay mode switching notification sent by the user equipment.
The wireless earphone in the embodiment of the application may be a bluetooth earphone, and may be connected to the user equipment through bluetooth technology.
S406, the wireless earphone switches the working mode of the local terminal to a low-delay working mode.
In the embodiment of the application, when the user equipment detects a low-delay communication request aiming at the wireless earphone, a quick track thread is created; reducing an audio data buffer area through the fast track thread, and canceling the operations of resampling the target audio data and/or processing the sound effect of the target audio data; when detecting that the audio coder/decoder selected by the local terminal is a first coder/decoder with non-low delay, switching the first coder/decoder into a second coder/decoder with low delay; the user equipment sends a low-delay mode switching notification to the wireless earphone; the wireless earphone receives a low-delay mode switching notification sent by user equipment; the wireless earphone switches the working mode of the local terminal to a low-delay working mode. Therefore, when the user equipment detects that the low-delay requirement exists, the user equipment reduces the delay and simultaneously sends a low-delay mode switching notice to the wireless earphone, when the wireless earphone receives the notice, the wireless earphone enters a low-delay mode, the delay of the earphone end is reduced, and through common optimization of the user equipment end and the earphone end, the total time from the user equipment to the playing of the sound of the wireless earphone is reduced, so that the problem that a user feels that the picture and the sound are not synchronous is solved, and better experience is obtained by using the wireless earphone in the scenes of playing, watching live broadcast, video and the like.
