Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

As users of electronic devices demand music experience, electronic devices begin to support playing audio files. The audio architecture of electronic equipment is similar to that of a computer, and is mainly completed by a processor and a built-in audio CODEC (codec). Among them, after the processor receives the input of the audio file, it converts it into an I2S signal, and transmits it to the CODEC to convert it into an analog signal, and then plays it.

Wherein, the electronic device may be any of various types of computer system devices that are mobile or portable and perform wireless communication.

With the further demands of users for music playback, more audio playback devices other than electronic devices have appeared. The audio playback device can receive audio data transmitted from the electronic device and play the audio data. Common audio playback devices include headphones, speakers, and car audio playback devices. Among them, as a transmission method, the electronic device can transmit the audio data to an external audio playback device for playback by means of Bluetooth transmission. In addition, the electronic device can also transmit audio data to the audio playback device in a manner based on the IEEE802.11 protocol.

The electronic device first encodes the audio data to be transmitted in the process of transmitting the audio data to the external audio playback device in a Bluetooth-based manner. Among them, the common Bluetooth audio audio encoding methods include: Apt-X encoding method, SBC encoding method and AAC encoding method.

In the research, the inventor found that in many scenarios, the encoding method of the audio data to be transmitted to the audio playback device is fixed by the electronic device. For example, in any scenario, the encoding method based on Apt-X The audio data is encoded, or the audio data is encoded based on the SBC encoding method, or the audio data is encoded based on the AAC method.

Therefore, the inventor proposes an encoding control method, an apparatus and an electronic device that can flexibly determine the encoding mode and improve the flexibility of the encoding mode in the present application.

The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Please refer to FIG. 1, a coding control method provided by this application is applied to electronic equipment, and the method includes:

Step S110: In the call state, obtain the current call feature parameters.

The call state may be a state in which the electronic terminal is in a state of establishing a voice communication channel with other terminal devices, or a state in which a voice communication channel has been established. Optionally, the voice communication channel may be a voice communication channel based on circuit switching or a voice communication channel established based on packet switching. Among them, as a method, the circuit switching method is a switching method for the purpose of circuit connection. Before communication, a physical channel exclusively occupied by the two parties should be established between the two communicating parties. The packet switching method is based on packet transmission and exchange. It is a store-and-forward switching method. The packets that are about to arrive at the switching device are first sent to the memory for temporary storage and processing, and then sent out when the corresponding output circuit is free. .

Wherein, the electronic device can use various ways to determine whether the electronic device is in a call state. Optionally, for the electronic device whose operating system is Android, it can be judged whether the electronic device is in a call state by detecting the return value of the object after the PhoneStateListener class is instantiated. As a way, the electronic device can register the PhoneStateListener object (usually by inheriting the PhoneStateListener class to complete some encapsulation) into the system telephony manager, and then implement the call through the callback method onCallStateChanged(int state, String incomingNumber) of the PhoneStateListener. Status detection. For example, if the value of the aforementioned state is TelephonyManager.CALL_STATE_IDLE, it means that the call in the call state is hung up, and the value of state is TelephonyManager.CALL_STATE_RINGING, which means that there is an incoming call but has not been answered, if the value of state is TelephonyManager .CALL_STATE_OFFHOOK, it can indicate that the electronic device is on a call.

In addition, it can also be determined whether the current state is in a call state by detecting some communication requests sent by the electronic device or the content of the received communication requests. For example, if it is detected that the electronic device establishes a voice communication channel by means of mobile communication, if it detects a traffic channel allocation request sent by the electronic device to the base station, or a traffic channel allocation command sent by the received base station, it can be determined that the electronic device The device is in a call state.

Step S120: Acquire the audio coding type corresponding to the call feature parameter.

It can be understood that the audio data to be transmitted by the electronic device to the audio playback device in the call state is obtained by the electronic device from another terminal device. For example, if the electronic device communicates with other terminals through the base station, in one case, the other terminals transmit the collected audio data to the electronic device, and then the electronic device transmits the audio data to the audio playback device. In this case, the electromagnetic environment where other terminals are located and the signal environment between the other terminals and the electronic device will affect the quality of the audio data.

In one way, the call characteristic parameter includes call quality information. Then, the step of acquiring the audio coding type corresponding to the call characteristic parameter may include: acquiring the audio coding type corresponding to the call quality information, wherein the lower the call quality represented by the call quality information, the The higher the bit rate of the audio coding type corresponding to the call quality information, so that in the case of a bad call environment, the electronic device can preserve the quality of the original audio data to the greatest extent, and then make the audio data played by the audio playback device. The audio data can be fidelity to the greatest extent, so that the user can hear the voice content clearly.

Wherein, in the case that the call characteristic parameter includes the call quality information, the call quality information may be determined by acquiring the parameters of the downlink voice during the call. In this case, the step of acquiring the current call feature parameters includes: acquiring parameters of the downlink voice during the call, and acquiring call quality information according to the parameters of the downlink voice.

Wherein, as a way, the acquired parameters of the downlink speech include the signal-to-noise ratio of the downlink speech. It should be noted that the signal-to-noise ratio, the English name is called SNR or S/N (SIGNAL-NOISE RATIO), also known as the signal-to-noise ratio. Refers to the ratio of signal to noise in an electronic device or electronic system. The signal here can refer to the electronic signal from outside the device that needs to be processed by this electronic device (such as the aforementioned downlink voice including audio data), and the noise refers to the original signal generated after passing through the device. A random extra signal (or information) that does not change with the original signal.

In the present application, as a way, the call quality information includes a quality level, for example, the number 1 indicates the level with the highest quality, the number 2 identifies the level with the second highest quality, and so on. In this case, then, the call quality information is a number characterizing the quality level. As one way, a mapping relationship between the signal-to-noise ratio and a number characterizing the quality level can be established. As shown in the table below:

ID SNR grade 1 a 1 2 b 2

Table 1

In Table 1, the field SNR represents the signal-to-noise ratio, and the field grade represents the quality level. Then for the case where the signal-to-noise ratio is a, the corresponding quality level is 1. For a signal-to-noise ratio of b, the corresponding quality level is 2. Correspondingly, different audio coding types can be determined for different quality levels. For example, the level 1 with the highest quality level may correspond to an audio coding type with a general coding rate. For the next highest quality level, level 2 or 3, it can correspond to the audio coding type with the highest coding rate. It can be understood that the higher the encoding bit rate, the higher the fidelity of the encoded audio data, and the audio playback device can play the original content of the audio data with higher quality.

Furthermore, as another way, the surrounding environment of the terminal device that has established a voice communication channel with the electronic device can also be used to determine the call quality information. It can be understood that, as shown in FIG. 2, in the figure, the terminal device 99 transmits the collected audio data to the base station 98, and the base station 98 transmits the audio data to the electronic device 100, and then the electronic device 100 transmits the audio data to the base station 98. Audio playback device (Bluetooth headset 97 shown). As another way, as shown in FIG. 3 , different from that shown in FIG. 2 , the terminal device 99 is connected to the network through the wireless access point 96 , and the electronic device 100 is connected to the network through the wireless access point 95 . In the network, the audio data collected by the terminal device can be firstly transmitted to the network through the wireless access point 96 , then transmitted to the wireless access point 95 , and then transmitted to the electronic device 100 .

In this case, the audio data to be transmitted by the electronic device to the audio playback device is initially collected by the terminal device that has established a voice communication channel with the electronic device. If the surrounding environment of the terminal device is not good, it may cause the poor quality of the audio data itself. For example, if there is a lot of noise in the surrounding environment, then the collected audio data will include the loud ambient noise. For another example, if the signal strength between the terminal device that has established the voice communication channel with the electronic device and the base station is not strong, then the audio data transmitted to the base station will suffer a great loss.

Then, as a way, the terminal device that has established a voice communication channel with the electronic device can transmit the environmental parameters characterizing the current surrounding environment (parameters characterizing the noise intensity or the signal strength connected to the base station) to the electronic device, so that The electronic device determines the call quality information according to the environmental parameters. Wherein, the terminal device that has established a voice communication channel with the electronic device can transmit the environmental parameters to the electronic device in various ways.

Optionally, the terminal device that has established a voice communication channel with the electronic device can add the environmental parameter to a certain parameter of the audio data, then in this case, the electronic device can, after receiving the audio data, The value of the certain parameter is extracted from the data to obtain the environment parameter. Furthermore, as another way, if both the electronic device and the terminal device that has established a voice communication channel with the electronic device can access the network in a communication mode other than the network protocol mode for establishing the voice communication channel, the electronic device can communicate with the electronic device. The terminal device whose device has established a voice communication channel can also upload the environmental parameters to the server first, and then the server pushes the environmental parameters to the electronic device.

For example, if a voice communication channel is established based on a mobile communication protocol such as 2G, 3G or 4G between the electronic device and the aforementioned terminal device. And if the electronic device and the aforementioned terminal device both support WIFI communication or both support the establishment of packet switching or circuit switching at the same time, the terminal device can transmit the collected environmental parameters to the server through WIFI or through packet interaction, and The server then transmits the environmental parameters to the electronic device by means of WIFI or by means of group interaction. It can be understood that, in order to facilitate the server to obtain which electronic device the received environmental parameters need to be transmitted to, when the terminal device uploads data to the server, the data not only includes the environmental parameters, but also includes the corresponding environmental parameters. The identifier of the electronic device, for example, the MAC address of the electronic device, so that the server can determine the electronic device corresponding to the MAC address from the electronic device that has established a network connection with itself as the recipient of the environmental parameter.

Wherein, as a way, the terminal device can organize the format of the data sent to the server in a self-defined data encapsulation way. In this case, the data sent by the electronic device to the server may include "##"+"44-45-53-54-00-00"+"N"+"80db"+"##*#". Among them, the symbol "##" represents the beginning of the data, and the symbol "###" represents the end of the data. And "44-45-53-54-00-00" indicates the MAC address of the electronic device, and "N" indicates that the entry data is about environmental noise, then "80db" indicates the environmental noise. It is understandable that after receiving this piece of data, the server will look for the IP address corresponding to the MAC address of 44-45-53-54-00-00, and if found, it will send a message to the electronic device corresponding to the IP address. 80db this noise parameter. It can be understood that, the server can also encapsulate the data to be sent based on the aforementioned custom data encapsulation manner.

It should be noted that, in this case, the communication quality information can still be the aforementioned quality level, and the relationship between the environmental parameters and the quality level can still be in the form of the aforementioned data table, which will not be repeated here.

In addition, in addition to the aforementioned manner of acquiring the call quality information, the call quality information may also be determined according to the uplink voice. In this case, the step of acquiring the current call characteristic parameter includes: recognizing the uplink voice during the call; and acquiring call quality information according to the content identified in the uplink voice.

It can be understood that the uplink voice is the voice collected by the electronic device and sent to the communication peer, that is, the voice sent to the terminal talking with the electronic device. Then, the electronic device can store the dictionary database locally in advance, and store the voice content representing the poor quality of the voice signal in the dictionary database. Then, when the electronic device collects the uplink voice content, it will recognize the collected uplink voice from it. content, and then identify whether there is content in the dictionary database in the uplink voice content, and if so, it can further determine the communication quality information corresponding to the identified content.

For example, as a method, if the level is still used to represent the communication quality information, if it is recognized that "I can't hear clearly" in the upstream voice content, the current communication quality is judged to be level 2, and if it is recognized that there is "I can't hear clearly" in the voice content Can't hear at all", the current communication quality is judged to be level 1. If it is recognized that the above-mentioned content does not appear in the upstream voice content, it can be determined that the current communication quality is level 3. Then, for different communication quality levels, different Bluetooth audio codes can be corresponding. Optionally, for Level 3, which represents the best communication quality, it can correspond to an audio coding method with a relatively low coding rate. In this way, it can ensure that the audio data can be transmitted to the audio playback device with high fidelity, and it will not consume too much. power and processor resources of many electronic devices. For the lower communication quality level 2 and level 3, when the quality of the audio data received by the electronic device itself is not high, the audio coding method with the relatively highest coding rate is adopted, so that the electronic device can broadcast the audio to the audio. When the device transmits the audio data, try not to distort the audio data, so as to avoid further distortion of the audio data.

It should be noted that the aforementioned call characteristic parameter including call quality information is an optional implementation of the present application, and in addition to this method, the call characteristic parameter may include the call object level. Then in this case, the step of acquiring the audio coding type corresponding to the call feature parameter includes: acquiring the audio coding type corresponding to the call object level, wherein the higher the call object level, the The code rate of the audio coding type corresponding to the calling object level is higher.

When a user communicates using an electronic device, for some call objects, the user can know that the communication object may be unclear or unable to speak fluently for some reasons. For example, for older communication partners. Then, as a way, the user of the electronic device can mark these users in the electronic device, then when the electronic device detects that the electronic device is in a call state, it can detect whether the current communication object has been marked as the aforementioned Users whose words are unclear or cannot express their voice fluently, or who have been marked as users who need a higher Bluetooth audio coding rate, if so, identify the user as a user with a higher user level, then the corresponding The bit rate of the audio encoding type is higher. In addition, for some more important communication objects, such as important customers, the user can also be marked as a user who needs a higher Bluetooth audio coding rate.

In addition, in another way, the call characteristic parameter includes the complexity of the electromagnetic environment in which the electronic device is located. In this application, the electronic device can determine the complexity of the current electromagnetic environment in various ways. Optionally, as a method, the electronic device may determine the number of currently searchable WLAN networks, and correspond the number of WLAN networks with the complexity of the electromagnetic environment. For example, when the number of WLAN networks is in the interval from 0 to a, the corresponding complexity is 1; if the number of WLAN networks is in the interval from a to b, the corresponding complexity is 2, and so on. In this case, a higher complexity can correspond to an audio coding mode with a higher coding rate.

Understandably, both WLAN networks and Bluetooth can work on the 2.4GHz band. However, the channel of the specific broadcast signal will still be different. Then, in addition to detecting the number of WLAN networks, the electronic device can also determine how many other devices are also using the channel where the currently broadcast Bluetooth signal is located, thereby obtaining the complexity of the electromagnetic environment. For example, when the number of channels occupied is in the interval from 0 to a, the corresponding complexity is 1. If the number of channels occupied is in the interval from a to b, the corresponding complexity is 2, and so on. In this case, a higher complexity can correspond to an audio coding mode with a higher coding rate. It can be understood that the channel occupancy refers to the number of other electronic devices when the channel currently used by the current electronic device to broadcast the Bluetooth signal is also used by other electronic devices.

Step S130: Encode the call audio data transmitted to the audio playback device based on the audio encoding type.

In one way, the electronic device may encode the call audio data transmitted to the audio playback device based on the audio encoding type when detecting that the electronic device is in the audio playback device connection state. Among them, it should be noted that the electronic device can play audio through its own configured audio playback module (such as a speaker or an earpiece), and can also transmit audio data to an external audio playback device, so that the external audio playback device can perform audio data playback on the audio data. play. In this case, the audio playback device connection status is used to indicate that the electronic device is currently transmitting audio data to an external audio playback device for playback.

Wherein, if the external audio playback device and the electronic device are in a wired or wireless connection state, the electronic device can be triggered to enter the audio playback device connection state. The wireless manner includes connection based on the IEEE802.11 protocol, or connection based on the Bluetooth communication protocol.

Then, in the case of connection based on the Bluetooth communication protocol, as a way to detect whether the electronic device is connected to a Bluetooth device through Bluetooth, if it is detected that the electronic device is connected to a Bluetooth device, it is detected whether the type of the Bluetooth device is an audio device type, If so, it is determined that the electronic device is in the audio playback device connection state. For example, in an electronic device based on the android operating system, the type of the device currently connected via Bluetooth can be determined based on the return value obtained by instantiating the BluetoothClass.Device class. If the returned value is AUDIO_VIDEO_CAMCORDER, it is characterized as an image acquisition device. If the returned value is AUDIO_VIDEO_CAR_AUDIO, it is a vehicle-mounted device. If the returned value is AUDIO_VIDEO_HIFI_AUDIO, it is characterized as an audio playback device or a video playback device. If the returned value is AUDIO_VIDEO_MICROPHONE, it represents the microphone.

In an encoding control method provided by the present application, in a call state, the current call feature parameter is obtained, the audio encoding type corresponding to the call feature parameter is obtained, and then the audio encoding type is transmitted to the audio playback device based on the audio encoding type. The call audio data is encoded. Therefore, in the process of transmitting the audio data of the call process to the audio playback device, the audio coding type for the audio data to be transmitted to the audio playback device can be determined according to the call characteristic parameter, so that the determination of the audio coding type can be more convenient. flexible.

Please refer to FIG. 4 , a coding control method provided by the present application is applied to an electronic device, and the method includes:

Step S210 : in a call state, detect whether the electronic device is in a vehicle-mounted mode.

Wherein, the electronic device can determine whether the vehicle in which it is located is in a driving state in various ways. In one way, when the electronic device detects that the installed navigation application program has turned on the navigation mode or starts navigation, it is determined that the vehicle is in a driving state. Among them, if the electronic device collects the driver's facial feature parameters in real time at the start of navigation, it will consume more power. Moreover, at the beginning of driving, the driver is less likely to experience driving fatigue, and the phenomenon of driving fatigue is more likely to occur when the vehicle is driving in a straight line for a long period of time. When the navigation application turns on the navigation mode or starts the navigation, it further detects that there is a straight road section exceeding the preset length on the route after the current position on the navigation route, and starts to obtain the facial feature parameters of the driver. The straight road segment is a road segment that does not need to change lanes or turn right-angle turns in the included route.

In another manner, the electronic device may determine that the vehicle in which the electronic device is located is in a driving state when it is detected that the electronic device is shaking at a preset frequency. It can be understood that when the vehicle is in a driving state, it will be in a state of relative shaking, and the shaking frequency will fluctuate within a certain range. When the electronic device detects that it is shaking within a certain range, it can determine the vehicle it is in. already in form.

Step S220: If it is detected that the electronic device is not in the vehicle-mounted mode, encode the call audio data transmitted to the audio playback device based on the default audio encoding type.

Step S230: If it is detected that the electronic device is in the vehicle-mounted mode, obtain current call feature parameters.

Step S240: Acquire the audio coding type corresponding to the call feature parameter.

Step S250: Encode the call audio data transmitted to the audio playback device based on the audio encoding type.

In an encoding control method provided by the present application, in a call state, it is detected whether an electronic device is in a vehicle-mounted mode, and if it is detected that it is in a vehicle-mounted mode, the current call feature parameter is obtained, and then the audio code corresponding to the call feature parameter is obtained. type, and then encode the call audio data transmitted to the audio playback device based on the audio encoding type. Therefore, in the process of transmitting the audio data of the call process to the audio playback device, the audio coding type for the audio data to be transmitted to the audio playback device can be determined according to the call characteristic parameter, so that the determination of the audio coding type can be more convenient. flexible. In addition, an encoding method with better transmission quality can be selected in the in-vehicle mode, so that the user can better hear the audio content, so that the user does not need to be distracted to recognize the content heard, which improves the safety of driving.

Optionally, the parameter obtaining unit 310 is specifically configured to identify the uplink voice during the call, and obtain the call quality information according to the content identified in the uplink voice.

In another manner, the call characteristic parameter includes a call object level. The encoding type acquiring unit 320 is specifically configured to acquire the audio encoding type corresponding to the call object level, wherein the higher the call object level, the higher the bit rate of the audio encoding type corresponding to the call object level.
