All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With the demand for music experience by users of electronic devices, electronic devices are beginning to support playing audio files. The audio architecture of electronic devices is similar to that of computers, and is mainly implemented by a processor and a built-in audio CODEC (coder-decoder). Wherein, the processor receives the input of the audio file, converts the input into an I2S signal, transmits the signal to the CODEC, converts the signal into an analog signal and plays the analog signal.
The electronic device may be any of various types of computer system devices that are mobile or portable and perform wireless communications, among others.
With the further demand of users for music playing, more audio playing devices other than electronic devices are available, and the audio playing devices can receive audio data transmitted by the electronic devices and play the audio data. Common audio playing devices include earphones, sound boxes, vehicle-mounted audio playing devices, and the like. As a transmission mode, the electronic device can transmit the audio data to an external audio playing device for playing in a bluetooth transmission mode. In addition, the electronic device can also transmit the audio data to the audio playing device by means of a mode based on the IEEE802.11 protocol.
The electronic equipment encodes the audio data to be transmitted in the process of transmitting the audio data to the external audio playing equipment in a Bluetooth-based mode. The common bluetooth audio coding methods include: Apt-X encoding, SBC encoding, and AAC encoding.
In many scenarios, for example, the electronic device encodes the audio data based on Apt-X encoding, encodes the audio data based on SBC encoding, or encodes the audio data based on AAC.
Therefore, the inventor proposes an encoding control method, an encoding control device and an electronic device, which can flexibly determine an encoding mode and improve the flexibility of the encoding mode.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, an encoding control method provided by the present application is applied to an electronic device, and the method includes:
step S110: and acquiring the current call characteristic parameters in the call state.
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 the voice communication channel is already established. Optionally, the voice communication channel may be a voice communication channel based on a circuit switching manner, or a voice communication channel established based on a packet switching manner. As one mode, the circuit switching mode is a switching mode for the purpose of circuit connection, and a physical channel exclusively occupied by two parties is established between the two parties of communication before communication. The packet switching method is a store-forward switching method, i.e. packets arriving at the switching equipment are sent to a memory for temporary storage and processing, and then sent out when the corresponding output circuit is available.
The electronic device may determine whether the electronic device is in a call state in various ways. Optionally, for the electronic device with the Android operating system, whether the electronic device is in a call state may be interpreted by detecting a return value of an object after the phonestatelelist class is instantiated. As one way, the electronic device may register a phonestalistener object (generally, inherits a phonestalistener class to complete some packages) in a system telephone management service (TelephonyManager), and then implement the detection of the call state through a phonestalistener callback method onCallStateChanged (String incominnumber). For example, if the value of the STATE is telephonymanager, call _ STATE _ IDLE, it indicates that the call in the call STATE is hung up, and if the value of the STATE is telephonymanager, call _ STATE _ RINGING, it indicates that there is an incoming call but the incoming call is not answered yet, and if the value of the STATE is telephonymanager, call _ STATE _ OFFHOOK, it may indicate that the electronic device is in a call.
In addition, whether the electronic device is in a call state currently can be judged 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 the voice communication channel in the mobile communication manner, it may be determined that the electronic device is in a call state if it is detected that the electronic device sends a traffic channel allocation request to the base station or receives a traffic channel allocation instruction sent by the base station.
Step S120: and acquiring the audio coding type corresponding to the call characteristic parameter.
It can be understood that the audio data to be transmitted to the audio playing device by the electronic device in the call state is acquired by the electronic device from another terminal device. For example, if the electronic device performs a voice call with another terminal through the base station, in one case, the other terminal transmits the collected audio data to the electronic device, and then the electronic device transmits the audio data to the audio playing device. In this case, the electromagnetic environment of the other terminal and the signal environment between the other terminal and the electronic device affect the quality of the audio data.
One way, the call characteristic parameter includes call quality information. The step of obtaining the audio coding type corresponding to the call characteristic parameter may comprise: the method comprises the steps of obtaining an audio coding type corresponding to call quality information, wherein the lower the call quality represented by the call quality information is, the higher the code rate of the audio coding type corresponding to the call quality information is, so that under the condition that a call environment is not good, the electronic equipment can maximally fidelity the quality of original audio data, and further maximally fidelity the audio data played by audio playing equipment, so that a user can clearly hear voice content.
Under the condition that the call characteristic parameters include call quality information, the call quality information can be determined by acquiring parameters of downlink voice in the call process. In this case, the step of acquiring the current call characteristic parameter includes: and acquiring parameters of downlink voice in the call process, and acquiring call quality information according to the parameters of the downlink voice.
As one mode, the acquired parameters of the downlink voice include a signal-to-noise ratio of the downlink voice. It should be noted that the SIGNAL-to-NOISE RATIO is called SNR or S/N (SIGNAL-to-NOISE RATIO) in english, and is also called SIGNAL-to-NOISE RATIO. Refers to the ratio of signal to noise in an electronic device or system. The signal may refer to an electronic signal (for example, the aforementioned downstream voice including audio data) from outside the device that needs to be processed by the electronic device, and the noise refers to an irregular extra signal (or information) that does not exist in the original signal generated after passing through the device, and the signal does not change with the change of the original signal.
In this application, as one approach, the call quality information includes quality levels, e.g., the number 1 indicates the highest quality level, the number 2 indicates the next highest quality level, and so on. Then in this case the call quality information is a number that characterizes the quality class. As one approach, a mapping between the signal-to-noise ratio and a number characterizing the quality level may be established. As shown in the following table:
| 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 a signal-to-noise ratio of a, the corresponding quality level is 1. For a signal-to-noise ratio of b, the corresponding quality level is 2. Accordingly, different audio coding types may 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. And for the level 2 or 3 with the highest quality level, the audio coding type with the highest coding rate can be corresponded. It can be understood that the higher the coding rate is, the higher the fidelity rate of the encoded audio data is, and the audio playing device can play the original content of the audio data with higher quality.
Furthermore, as another mode, the call quality information may be determined according to the surrounding environment where the terminal device that has established the voice communication channel with the electronic device is located. It is understood that as shown in fig. 2, the terminal device 99 transmits the collected audio data to the base station 98, the base station 98 transmits the audio data to the electronic device 100, and the electronic device 100 transmits the audio data to the audio playing device (illustrated as the bluetooth headset 97). Alternatively, as shown in fig. 3, unlike the method 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, so that the audio data collected by the terminal device may be transmitted to the network through the wireless access point 96, then to the wireless access point 95, and then to the electronic device 100.
In this case, the audio data to be transmitted to the audio playing device by the electronic device is originally collected by the terminal device that establishes the voice communication channel with the electronic device, and if the surrounding environment of the terminal device that establishes the voice communication channel with the electronic device is not good, the quality of the audio data itself may be poor. For example, if the ambient environment is noisy, then the captured audio data may include loud ambient noise. For another example, if the signal strength between the terminal device and the base station that establish the voice communication channel with the electronic device is not strong, a large loss of audio data transmitted to the base station may be caused.
Then, as one way, the terminal device that has established a voice communication channel with the electronic device may transmit an environmental parameter (a parameter representing the intensity of noise or the intensity of a signal connected to a base station) representing the current surrounding environment to the electronic device, so that the electronic device determines call quality information according to the environmental parameter. The terminal device establishing the voice communication channel with the electronic device can transmit the environment parameters to the electronic device in various ways.
Optionally, the terminal device that establishes the voice communication channel with the electronic device may add the environment parameter to a certain parameter of the audio data, and in this case, the electronic device may extract a value of the certain parameter from the audio data after receiving the audio data, so as to obtain the environment parameter. Furthermore, as another mode, if both the electronic device and the terminal device that establishes the voice communication channel with the electronic device can access the network in a communication mode other than the network protocol mode that establishes the voice communication channel, the terminal device that establishes the voice communication channel with the electronic device may also upload the environment parameter to the server first, and then the server pushes the environment parameter to the electronic device.
For example, if the electronic device and the terminal device are in a voice communication channel established based on a mobile communication protocol such as 2G, 3G, or 4G. And under the condition that the electronic equipment and the terminal equipment both support WIFI communication or both support the simultaneous establishment of packet switching or circuit switching, the terminal equipment can transmit the acquired environmental parameters to the server in a WIFI or packet interaction mode, and the server transmits the environmental parameters to the electronic equipment in a WIFI or packet interaction mode. It can be understood that, in order to facilitate the server to obtain to which electronic device the received environment parameter needs to be transmitted, when the terminal device uploads the data to the server, the data includes not only the environment parameter but also an identifier of the electronic device corresponding to the environment parameter, for example, a MAC address of the electronic device, so that the server can determine, from the electronic devices that have established network connection with itself, the electronic device corresponding to the MAC address as a receiver of the environment parameter.
As one way, the terminal device may organize the format of the data sent to the server in a customized data encapsulation manner. In this case, the data transmitted by the electronic device to the server may include "#" + "44-45-53-54-00-00" + "N" + "80 db" + "#". Wherein the symbol "###" characterizes the beginning of the data and the symbol "##" characterizes the end of the data. And "44-45-53-54-00-00" indicates the MAC address of the electronic device, and "N" indicates the entry data with respect to the ambient noise, then "80 db" indicates the ambient noise. It can be understood that, after receiving the piece of data, the server searches for the IP address corresponding to the MAC address of 44-45-53-54-00-00, and if the IP address is found, sends 80db of the noise parameter to the electronic device corresponding to the IP address. It will be appreciated that the server may also package the data to be transmitted based on the aforementioned custom data packaging approach.
It should be noted that, in this case, the communication quality information may still be the quality level, and the association relationship between the environment parameter and the quality level may still adopt the manner of the data table, which is not described herein again.
In addition, in addition to the aforementioned manner of acquiring call quality information, the call quality information may also be determined according to the uplink speech. In this case, the step of acquiring the current call characteristic parameter includes: identifying uplink voice in the communication process; and acquiring the call quality information according to the content identified in the uplink voice.
It can be understood that the uplink voice is a voice collected by the electronic device and sent to the opposite communication terminal, that is, a voice sent to the terminal communicating with the electronic device. Then, the electronic device may store the voice content representing poor quality of the voice signal in the dictionary library in advance in the local storage dictionary library, and then after acquiring the uplink voice content, the electronic device may recognize the acquired uplink voice content from the uplink voice content, and then recognize whether the uplink voice content has the content existing in the dictionary library, and if so, may further determine the communication quality information corresponding to the recognized content.
For example, as one mode, if the communication quality information is still expressed by a level, if "i am not clearly heard" is recognized in the upstream voice content, the current communication quality is judged to be level 2, and if "i am not clearly heard" is recognized in the voice content, the current communication quality is judged to be level 1. If the uplink voice content is recognized to have no content, the current communication quality can be determined to be 3 levels. Different bluetooth audio encodings may be corresponded to different communication quality levels. Optionally, the 3-level audio coding mode representing the best communication quality may correspond to an audio coding mode with a relatively low coding rate, so that it may be ensured that audio data may be transmitted to the audio playing device with high fidelity, and excessive power consumption of the electronic device and processor resources may not be consumed. And for the 2-level and 3-level audio coding modes with lower communication quality and the condition that the quality of the audio data received by the electronic equipment is not high, the audio coding mode with the highest coding rate is adopted, so that the audio data distortion cannot occur as much as possible in the process of transmitting the audio data to the audio playing equipment by the electronic equipment, and the further distortion of the audio data is avoided.
It should be noted that, the aforementioned call characteristic parameter including the call quality information is an optional implementation manner of the present application, and besides this manner, the call characteristic parameter may include a call object level. In this case, the step of obtaining the audio coding type corresponding to the call characteristic parameter comprises: and acquiring an audio coding type corresponding to the call object grade, wherein the higher the call object grade is, the higher the code rate of the audio coding type corresponding to the call object grade is.
When a user uses the electronic device to communicate, for some call objects, the user can know that the communication object may have speech expression with unclear wording or no fluency for some reasons. For example, for older communication partners. As a mode, the user of the electronic device may mark the users in the electronic device, and when the electronic device detects that the electronic device is in a call state, it may be detected whether the current communication object is a user who has been marked as the user with unclear wording or no fluency and performs speech expression, or a user who has been marked as a user requiring a higher bluetooth audio coding rate, and if so, the user is identified as a user with a higher user level, and the code rate of the audio coding type corresponding to the user level is higher. In addition, for some more important communication objects, such as important clients, the user can also mark as a user needing a higher bluetooth audio coding rate.
Further, the call characteristic parameter may alternatively comprise a complexity of an electromagnetic environment in which the electronic device is located. In the present application, the electronic device may determine the complexity of the current electromagnetic environment in a number of ways. Optionally, as a manner, the electronic device may determine the number of WLAN networks that can be currently searched, and correspond the number of WLAN networks to the complexity of the electromagnetic environment. For example, when the number of WLAN networks is in the section from 0 to a, the corresponding complexity is 1, and if the number of WLAN networks is in the section from a to b, the corresponding complexity is 2, and so on. In this case, higher complexity may correspond to an audio coding scheme with a higher coding rate.
It will be appreciated that both WLAN networks and bluetooth may operate in the 2.4GHz band. However, the channel of the signal it is specifically broadcasting may still vary. Besides detecting the number of WLAN networks, the electronic device can also determine how many other devices are in use on the channel where the currently broadcasted bluetooth signal is located, thereby obtaining the complexity of the electromagnetic environment. For example, when the number of occupied channels is in the section from 0 to a, the corresponding complexity is 1, and if the number of occupied channels is in the section from a to b, the corresponding complexity is 2, and so on. In this case, higher complexity may correspond to an audio coding scheme with a higher coding rate. It is understood that the channel occupation refers to the number of other electronic devices in the case that the current electronic device broadcasts the channel used by the bluetooth signal and other electronic devices are also used.
Step S130: and coding the call audio data transmitted to the audio playing equipment based on the audio coding type.
As one way, the electronic device may encode call audio data transmitted to the audio playback device based on the audio encoding type if it is detected that the electronic device is in the audio playback device connection state. It should be noted that the electronic device may play audio through an audio playing module (e.g., a speaker or an earphone) configured by the electronic device, or may transmit the audio data to an external audio playing device, so that the external audio playing device plays the audio data. In this case, the connection status of the audio playback device is used to indicate that the electronic device is currently transmitting audio data to an external audio playback device for playback.
The external audio playing device and the electronic device are in a wired or wireless connection state, and both the external audio playing device and the electronic device can be triggered to enter the audio playing device connection state. The wireless mode includes connection based on an IEEE802.11 protocol or connection based on a Bluetooth communication protocol.
Then, under the condition of connection based on a bluetooth communication protocol, as a mode, detecting whether the electronic device is connected with a bluetooth device through bluetooth, if the electronic device is detected to be connected with the bluetooth device, detecting whether the type of the bluetooth device is an audio device type, and if so, judging that the electronic device is in an audio playing device connection state. For example, in an android operating system based electronic device, the type of device currently connected through bluetooth may be determined based on a return value obtained by instantiating a bluetooth class. If the returned value is AUDIO _ VIDEO _ CAMCORDER, the image acquisition device is characterized. If the returned value is AUDIO _ VIDEO _ CAR _ AUDIO, the vehicle-mounted device is characterized. If the returned value is AUDIO _ VIDEO _ HIFI _ AUDIO, the AUDIO playback device or the VIDEO playback device is characterized. If the returned value is AUDIO _ VIDEO _ MICROPHONE, then the MICROPHONE is characterized.
According to the coding control method, in a call state, a current call characteristic parameter is acquired, an audio coding type corresponding to the call characteristic parameter is acquired, and call audio data transmitted to audio playing equipment is coded based on the audio coding type. Therefore, in the process of transmitting the audio data in the call process to the audio playing device, the audio coding type of the audio data to be transmitted to the audio playing device can be determined according to the call characteristic parameters, and the determination of the audio coding type can be more flexible.
Referring to fig. 4, an encoding control method provided by the present application is applied to an electronic device, and the method includes:
step S210: and detecting whether the electronic equipment is in a vehicle-mounted mode or not in a call state.
The electronic device can determine whether the vehicle is in a driving state in various ways. As one way, when the electronic device detects that the navigation application installed therein turns on the navigation mode or starts navigation, it is determined that the vehicle is in a driving state. If the electronic equipment collects the facial feature parameters of the driver in real time at the beginning of the navigation, more electric quantity can be consumed. In addition, at the starting time of driving, the driver is not easy to have driving fatigue, and the driving fatigue phenomenon is more easy to occur when the vehicle is in the process of straight-line driving for a long time period, as a mode, when the electronic device detects that the navigation application installed in the electronic device starts the navigation mode or starts navigation, and further detects that a straight-line road section with the length exceeding the preset length exists in the route after the current position on the navigation route, the electronic device starts to acquire the facial feature parameters of the driver. The straight road section is a road section which does not need to change roads or turn right angles in included paths.
Alternatively, the electronic device may determine that the vehicle in which the electronic device is located is in the driving state when the electronic device detects shaking at a preset frequency. It is understood that when the vehicle is in a running state, the vehicle is in a relatively shaking state, and the shaking frequency fluctuates within a certain range, and when the electronic device detects shaking of the electronic device in the certain range, it can be determined that the vehicle is in a form state.
Step S220: and if the electronic equipment is detected not to be in the vehicle-mounted mode, encoding the call audio data transmitted to the audio playing equipment based on the default audio encoding type.
Step S230: and if the electronic equipment is detected to be in the vehicle-mounted mode, acquiring the current call characteristic parameters.
Step S240: and acquiring the audio coding type corresponding to the call characteristic parameter.
Step S250: and coding the call audio data transmitted to the audio playing equipment based on the audio coding type.
According to the encoding control method, whether the electronic equipment is in the vehicle-mounted mode or not is detected in the call state, if the electronic equipment is detected to be in the vehicle-mounted mode, the current call characteristic parameter is acquired, the audio encoding type corresponding to the call characteristic parameter is acquired, and then call audio data transmitted to the audio playing equipment is encoded based on the audio encoding type.
