In the related art, a method for transferring a voice call of a mobile terminal to a vehicle so as to perform a voice call through a microphone and a speaker of the vehicle is generally used to transfer a voice call to a vehicle through a bluetooth method. However, the inventor has found in long-term research that when a voice call is transferred to a vehicle by means of bluetooth, the voice call is transmitted through a bluetooth physical link. This process may perform lossy compression on the voice call data, thereby causing a reduction in the quality of the voice call data transmitted to the vehicle, and further causing a problem of poor call quality.
In order to solve the above problems, the inventor provides a content delivery method, a content delivery device, a content delivery server and a storage medium provided by the present application, based on an android native audio hardware abstraction layer and a newly added in-vehicle data processing process, data transmission between a mobile terminal and a vehicle through the audio hardware abstraction layer can be realized, compatibility of a data transmission process can be improved by using the android native audio hardware abstraction layer, in addition, since lossy compression is not performed on audio data, the tone quality of voice call data transmitted to the vehicle can also be ensured, thereby improving the vehicle call quality.
Before the technical solution of the embodiment of the present disclosure is explained in detail, an application environment of the embodiment of the present disclosure is explained.
As shown in fig. 1, fig. 1 is a schematic diagram of an application environment according to an embodiment of the present disclosure. The system comprises a mobile terminal 102, a communication terminal 101 for communicating with the mobile terminal 102, and a vehicle 103 for establishing communication connection with the mobile terminal 102.
The vehicle may establish a communication connection with the mobile terminal through a vehicle-mounted terminal (vehicle machine), and the vehicle-mounted terminal may include a speaker and a microphone. The communication terminal and the mobile terminal can be a mobile phone, a notebook, a tablet computer, a wearable device and the like.
In the call method implemented by applying the application environment of fig. 1, the voice data of the call end may be transmitted to the mobile terminal, and the mobile terminal sends the voice data to the vehicle and then plays the voice data through the audio data device (e.g., vehicle-mounted speaker) of the vehicle; in addition, the audio acquisition device (such as an on-board microphone) of the vehicle can acquire the voice data in the local environment of the vehicle and send the voice data to the mobile terminal, and the mobile terminal sends the voice data to the call terminal, so that the whole vehicle call process is completed.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a flow chart illustrating a vehicle communication method according to an exemplary embodiment, which may be applied to a mobile terminal (e.g., the mobile terminal 102 shown in fig. 1), the mobile terminal including: cell-phones, notebook, panel computer, wearable equipment etc.. The method comprises the following steps:
and S210, establishing communication connection with the vehicle.
In the embodiment of the disclosure, in order to implement the vehicle communication method, that is, in order to transfer the voice communication of the mobile terminal to the vehicle, the mobile terminal may first establish communication connection with the vehicle.
In some embodiments, the mobile terminal may establish a communication connection with the vehicle through a USB mode, a WIFI mode, or the like.
It can be understood that after the mobile terminal establishes the communication connection with the vehicle through the USB mode or the WIFI mode, the mobile terminal may perform data transmission with the vehicle through the corresponding protocol. For example, after the mobile terminal establishes a communication connection with the vehicle in a USB manner, data transmission may be performed through a USB protocol. For another example, after the mobile terminal establishes a communication connection with the vehicle in a WIFI manner, data transmission may be performed through a TCP/IP protocol.
It should be noted that there are many situations when the mobile terminal establishes a communication connection with the vehicle, for example, the mobile terminal may establish a communication connection with the vehicle before receiving the initiation of the voice call, or for example, the mobile terminal may establish a communication connection with the vehicle after receiving the voice call, that is, the mobile terminal may establish a communication connection with the vehicle during the voice call. The time for establishing the communication connection between the mobile terminal and the vehicle is not limited in the embodiment of the disclosure.
S220, under the condition that the voice call program of the mobile terminal is in a call state, caching first voice data received by the voice call program into a first cache region in an audio hardware abstraction layer.
The audio hardware abstraction layer (audiohal) is a module part native to android, and the android native audio hardware abstraction layer is beneficial to keeping the compatibility and stability of a voice data transmission process.
In the embodiment of the present disclosure, the voice call program in the call state may be understood as that the mobile terminal has answered the voice call made by the call end, and at this time, the voice call program may receive the first voice data from the call end. Therefore, on the premise that the mobile terminal establishes communication connection with the vehicle, if the first voice data is received, the mobile terminal can cache the first voice data in the first cache region in the audio hardware abstraction layer.
In some embodiments, the first buffer may be a first-in first-out data buffer, thereby ensuring the playing timing of the voice data.
Among them, the voice call program may be of various types. Alternatively, the program may be a program based on a network over ip (VOIP) or a program based on a telephone network call, where the program based on the network call may be, for example, a WeChat Voice or a QQ Voice, and the program based on the telephone network call may be understood as a program that conventionally performs a call through a telephone card, for example, a program corresponding to a dial interface built in a mobile phone. Thus, the voice call program in the embodiment of the present disclosure includes a program based on a network call and a program based on a telephone network call.
And S230, acquiring the first voice data from the first cache region through a vehicle-machine data processing process in the mobile terminal, and sending the first voice data to the vehicle for playing.
In the embodiment of the disclosure, a vehicle-mounted data processing process is further arranged in the mobile terminal, and the process is used for transmitting voice data with a vehicle. Therefore, after the first voice data received by the voice call program is cached in the first cache region in the audio hardware abstraction layer, the vehicle-mounted data processing process can acquire the first voice data from the first cache region and then send the first voice data to the vehicle through the corresponding communication connection mode so as to enable the speaker of the vehicle to play.
In some embodiments, the in-vehicle data processing process may further perform format conversion on first voice data to be sent to the vehicle to obtain first voice data of a protocol corresponding to the communication connection mode, so as to send the first voice data to the vehicle in a corresponding communication mode.
And S240, receiving second voice data sent by the vehicle, and caching the second voice data into a second cache region in the audio hardware abstraction layer through the vehicle-mounted data processing process.
As can be seen from the foregoing, the vehicle-mounted audio collection device may also collect the local voice data of the vehicle, that is, the second voice data, and send the second voice data to the mobile terminal through the connection with the mobile terminal, and at this time, the mobile terminal may receive the second voice data sent by the vehicle.
In the embodiment of the present disclosure, in order to facilitate that a subsequent voice call program can obtain the second voice data, after receiving the second voice data, the mobile terminal may cache the second voice data in the second cache region in the audio hardware abstraction layer through the in-vehicle data processing process.
And S250, acquiring second voice data from the second cache region through the voice call program, and sending the second voice data to a call end for carrying out call with the mobile terminal.
In the embodiment of the disclosure, after the car machine data processing process caches the second voice data in the second cache region in the audio hardware abstraction layer, the voice call program may obtain the second voice data from the second cache region, and send the second voice data to the call end that makes a call with the mobile terminal.
It can be known that the steps S220 and S230 may correspond to a process of transmitting downlink voice data of a call end to a vehicle for playing, and the steps S240 and S250 may correspond to a process of transmitting uplink voice data of a vehicle local to the call end for playing, where in an actual call process, voice data in two directions may be processed in parallel, or may be processed successively according to an actual situation, and therefore, in some alternative implementations, an execution sequence of a part of the flow in the embodiment of the present invention may also be executed in an execution sequence different from that described in the foregoing specific embodiment. For example, the partial flows (steps S220, S230, and steps S240, S250) may be executed substantially in parallel, or they may be executed in reverse order depending on the functions involved.
By adopting the method, after the mobile terminal is in communication connection with the vehicle, under the condition that the voice call program of the mobile terminal is in a call state, the first voice data received by the voice call program can be cached in the first cache region in the audio hardware abstraction layer, the first voice data can be obtained from the first cache region through the vehicle-mounted machine data processing process in the mobile terminal, and the first voice data can be sent to the vehicle for playing; or the second voice data sent by the vehicle can be received, the second voice data is cached in a second cache region in the audio hardware abstraction layer through the vehicle-mounted computer data processing program, the second voice data is obtained from the second cache region through the voice communication program, and the second voice data is sent to a communication terminal for communicating with the mobile terminal. In the vehicle communication method of the embodiment of the disclosure, based on the native audio hardware abstraction layer of android and the newly added vehicle machine data processing process, data transmission between the mobile terminal and the vehicle through the audio hardware abstraction layer can be realized, the compatibility of the data transmission process can be improved by using the native audio hardware abstraction layer of android, and in addition, the tone quality of the voice communication data transmitted to the vehicle can also be ensured due to the fact that lossy compression is not performed on the audio data, so that the vehicle communication quality is improved.
Referring to fig. 3, fig. 3 is a flow chart illustrating a vehicle communication method according to an exemplary embodiment, which may be applied to a mobile terminal (e.g., the mobile terminal 102 shown in fig. 1), the mobile terminal including: cell-phones, notebook, panel computer, wearable equipment etc.. The method comprises the following steps:
and S310, establishing communication connection with the vehicle.
And S320, under the condition that the voice call program of the mobile terminal is in a call state, calling an audiotrack interface provided by the audio hardware abstraction layer, and caching the first voice data into a first cache region.
And S330, calling an audio interface provided by an audio hardware abstraction layer through a vehicle-machine data processing process in the mobile terminal, acquiring first voice data from the first cache region, and sending the first voice data to the vehicle for playing.
And S340, receiving second voice data sent by the vehicle, calling an audiotrack interface provided by the audio hardware abstraction layer through the vehicle data processing process, and caching the second voice data into a second cache region.
And S350, calling an audio interface provided by the audio hardware abstraction layer through the voice call program, acquiring second voice data from the second cache region, and sending the second voice data to a call end for carrying out call with the mobile terminal.
The AudioTrack interface class manages and plays a single audio resource for Java applications.
The audiocord interface class implements the collection of audio data.
The embodiment of the disclosure provides a data caching and data acquisition implementation method. The mobile terminal can call an audiotrack interface provided by the audio hardware abstraction layer, cache the first voice data in the first cache region, call an audiocord interface provided by the audio hardware abstraction layer through a car machine data processing process in the mobile terminal, and obtain the first voice data from the first cache region. In addition, the mobile terminal can call an audiotrack interface provided by the audio hardware abstraction layer through the car machine data processing process, cache the second voice data in the second cache region, and call an audiocord interface provided by the audio hardware abstraction layer through the voice call program, so as to obtain the second voice data from the second cache region.
For the content not described in detail in the steps S310 to S350, reference may be made to the description of the steps S210 to S250, and details are not repeated here.
By adopting the method, based on the android native audio hardware abstraction layer and the newly added vehicle data processing process, data can be transmitted between the mobile terminal and the vehicle through the audio hardware abstraction layer, the compatibility of the data transmission process can be improved by using the android native audio hardware abstraction layer, in addition, the tone quality of voice call data transmitted to the vehicle can be ensured due to the fact that lossy compression is not carried out on the audio data, and therefore the vehicle call quality is improved.
In addition, considering that if there are multiple audio output devices (for example, a speaker of a mobile terminal and a speaker of a vehicle) playing together in a call process, there are situations such as overlapping or noise of the audio played in the call process, and therefore, in order to avoid situations such as overlapping or noise of the audio played in the call process, in some embodiments, the method of the embodiment of the present disclosure may further include: and in response to the fact that the voice call program of the mobile terminal is in a call state, disabling the audio playing device of the mobile terminal and starting a data processing process of the mobile phone.
The audio playing device which disables the mobile terminal may be an audio playing device which prohibits the first audio data from being sent to the mobile terminal, or may be an audio playing device which allows the first audio data to be sent to a certain terminal, but prohibits the audio playing device of the mobile terminal from playing the first beverage data.
In addition, in order to avoid situations such as overlapping or noise of the audio played in the call process, in another embodiment, the method according to the embodiment of the present disclosure may further include: and detecting the state of the communication connection established between the mobile terminal and the vehicle, and under the condition that the detected state of the communication connection established between the mobile terminal and the vehicle is the state representing the established connection, forbidding the audio playing equipment of the mobile terminal and starting the vehicle-mounted machine data processing process.
In the embodiment of the present disclosure, after the mobile terminal establishes a communication connection with the vehicle, the audio playing device of the mobile terminal may be disabled, and the in-vehicle data processing process may be enabled.
In addition, in some embodiments, an audio capture device of the mobile terminal (e.g., a microphone of the mobile terminal) may be disabled while an audio playback device of the mobile terminal is disabled. When the audio acquisition device of the mobile terminal is forbidden, the audio acquisition device of the vehicle can be adopted to acquire the local voice data of the vehicle.
