Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
The current electronic device 100 generally has a Bluetooth (BT) module and a WiFi (Wireless Fidelity) module. The Bluetooth module can be a chip basic circuit set integrating a Bluetooth function and used for wireless network communication; the Wi-Fi module can be an embedded module which converts a serial port or TTL level into a level meeting the Wi-Fi wireless network communication standard, a wireless network protocol IEEE802.11b.g.n protocol stack and a TCP/IP protocol stack are built in the Wi-Fi module, and the hardware equipment is embedded into the Wi-Fi module and can be directly connected to the Internet by utilizing Wi-Fi. The electronic device 100 can perform bluetooth connection with a bluetooth device 200 (e.g., an audio playing device such as a bluetooth headset or a bluetooth sound box, or a video playing device such as a projector or a television) through a bluetooth module; the electronic device 100 may also perform a WiFi connection through a WiFi module, for example, the electronic device 100 connects to a wireless local area network through the WiFi module to perform data interaction with a server 300 (e.g., a cloud server, a mobile phone, a computer, a tablet computer, etc.), as shown in fig. 1.
As the demand of users for electronic devices increases, the electronic devices start to support playing audio data in order to meet the demands of users and provide convenience for users, wherein the audio architecture of the electronic devices is similar to that of computers, and is mainly completed by processors and built-in audio CODECs (CODECs). Specifically, the processor receives the input of audio data, converts the audio data into an I2S signal, transmits the I2S signal to the CODEC, converts the I2 signal into an analog signal, and plays the analog signal.
Further, the electronic device may be connected to an external audio playing device, and the audio playing device plays audio data, specifically, the audio playing device may receive the audio data transmitted by the electronic device and play the audio data, where the audio playing device may include an earphone, a sound box, a vehicle-mounted device, and the like. In many cases, the electronic device and the external audio playing device need to use a network for data transmission, for example, the electronic device and the audio playing device need to use a Wireless Fidelity (WiFi) connection for data transmission, or the electronic device and the audio playing device need to use a Bluetooth (BT) connection for data transmission, and optionally, in a general case, the electronic device may be connected with the audio playing device through Bluetooth, and transmit the audio data to the audio playing device through Bluetooth for playing. However, since bluetooth transmission is wireless transmission, it is easily affected by the surrounding environment, and if the surrounding environment is poor (there is interference) and music playing is performed always in a high bit rate manner, the music jamming phenomenon easily occurs at the audio playing device end, which affects music experience. However, the current practice is to set a relatively fixed playing code rate, which is not changed by the change of the surrounding environment.
In view of the above problems, the inventor finds, through long-term research, that a code rate optimization method, an apparatus, an electronic device, and a storage medium provided in the embodiments of the present application are provided, where the code rate of corresponding audio data is obtained according to the signal strength between the electronic device and an audio playing device, and then the audio data is updated and transmitted according to the code rate, so as to reduce music playing jams and improve music experience. The specific code rate optimization method is described in detail in the following embodiments.
Examples
Referring to fig. 2, fig. 2 is a flowchart illustrating a code rate optimization method according to an embodiment of the present application. The code rate optimization method is used for acquiring the coding rate of the corresponding audio data according to the signal strength between the electronic equipment and the audio playing equipment, and updating and transmitting the audio data according to the coding rate so as to reduce the music playing stagnation and improve the music experience. In a specific embodiment, the code rate optimization method is applied to the code rate optimization apparatus 400 shown in fig. 5 and the electronic device 100 (fig. 6) configured with the code rate optimization apparatus 400. The specific flow of the embodiment will be described below by taking an electronic device as an example, and it is understood that the electronic device applied in the embodiment may be a smart phone, a tablet computer, a wearable electronic device, a vehicle-mounted device, a gateway, and the like, and is not limited specifically herein. As will be described in detail with respect to the flow shown in fig. 2, the code rate optimization method may specifically include the following steps:
step S101: when the electronic equipment is connected to audio playing equipment through Bluetooth, the signal intensity between the electronic equipment and the audio playing equipment is detected in real time.
In this embodiment, first, the connection state of the electronic device is detected, it can be understood that the connection state of the electronic device at least may include a network connection state, a network non-connection state, and a network connection in-progress state, and further, when it is detected that the electronic device is in the network connection state, the connection mode of the electronic device continues to be detected, and it can be understood that the connection mode of the electronic device may include mobile network connection, for example: 4G network connection, 3G network connection, 2G network connection, etc.; may include wireless network connections such as: a WiFi connection or a MiFi connection; but may also include, without limitation, a bluetooth connection, etc.
As one mode, the audio playing device may include a bluetooth module, and the audio playing device may perform bluetooth connection with the electronic device through the bluetooth module. Wherein, when detecting that the electronic device is connected to an audio playing device through bluetooth, for example: when detecting that the electronic equipment and the audio playing equipment both start the Bluetooth and the electronic equipment and the audio playing equipment are successfully paired, the electronic equipment can be represented to be connected to the audio playing equipment through the Bluetooth.
Further, in this embodiment, it may also be detected whether the device connected to the electronic device through bluetooth is an audio playing device, wherein, in the electronic device based on the android operating system, the device type currently connected through bluetooth may be determined by a return value obtained based on instantiating a bluetooth class. If the returned value is AUDIO _ VIDEO _ CAMCORDER, the image acquisition equipment is characterized; if the returned value is AUDIO _ VIDEO _ CAR _ AUDIO, the vehicle-mounted equipment is characterized; if the returned value is AUDIO _ VIDEO _ HIFI _ AUDIO, the AUDIO or VIDEO playing device is characterized as an AUDIO playing device or a VIDEO playing device, such as a bluetooth headset; if the returned value is AUDIO _ VIDEO _ MICROPHONE, it is characterized as a MICROPHONE.
When it is determined that the electronic device is connected to the audio playing device through the bluetooth, the signal strength between the electronic device and the audio playing device is detected in real time, and it can be understood that the signal strength between the electronic device and the audio playing device changes along with time and other factors, so that in this embodiment, the signal strength between the electronic device and the audio playing device is detected in real time, and the accuracy of signal strength detection can be improved. As one way, the signal strength between the electronic device and the audio playback device can be obtained by: firstly, adding registration scanning broadcast in an oncreate method; then, a BroadcastReceiver broadcast object is newly established, an inner onReceive method is realized, and rsi (signal intensity) is obtained at onReceive; as another mode, the signal strength between the electronic device and the audio playing device may also be obtained by testing through network speed measurement software, which is not limited herein.
Step S102: and when the electronic equipment runs a target application program, acquiring the encoding rate of the audio data corresponding to the signal intensity in real time, wherein the target application program at least supports the audio data.
In this embodiment, the application programs run by the electronic device may include an application program running in a foreground of the electronic device, an application program running in a background of the electronic device, or an application program that is switched to run in the foreground and the background of the electronic device. Specifically, an application program running in the foreground refers to an application program which can generally interact with a user and can run in the foreground, and the application program can be suspended when the application program is not visible (such as games); background running applications mean very limited interaction with the user, except during configuration, where other times of the lifetime are hidden (e.g., SMS auto-answer program and alarm clock program); the application program which is switched to run in the foreground and the background of the electronic equipment refers to the application program which can be switched between the foreground and the background at will. It is understood that when an application is not killed (kill), the application is characterized as running on the electronic device.
Further, a target application is determined from the applications run by the electronic device, where the target application may include a single application or may include multiple applications, and is not limited herein. In this embodiment, the target application at least supports audio data, that is, the target application has at least audio output, for example, the target application may include a music playing application, a video playing application, a talking application, a game application, and the like, and the application may output audio data or may output audio data and image data at the same time.
Further, when it is determined that the electronic device runs the target application program, the encoding rate of the audio data corresponding to the detected signal strength is obtained, and similarly, since the signal strength between the electronic device and the audio playing device may change with time and other factors, in this embodiment, the encoding rate of the audio data corresponding to the signal strength is obtained in real time. As a mode, an algorithm between the signal intensity and the encoding rate is established in advance, and after the signal intensity between the electronic device and the audio playing device is detected, the encoding rate corresponding to the signal intensity is calculated through the algorithm; as another mode, a mapping table is set and stored in the electronic device in advance, and is recorded as a preset mapping table, as shown in table 1, where the preset mapping table at least includes a correspondence between signal strength and coding rate, it can be understood that the correspondence may be that signal strength corresponds to coding rate one by one, or that multiple signal strengths correspond to one coding rate, and is not limited herein. Further, after the signal strength is obtained, the encoding rate corresponding to the signal strength is searched from the preset mapping relation table through the preset mapping relation table to be used as the encoding rate of the audio data.
TABLE 1
| Signal strength | Encoding rate |
| A1 | B1 |
| A2 | B2 |
| A3 | B3 |
In this embodiment, the signal strength is positively correlated with the coding rate, that is, the larger the signal strength is, the larger the corresponding coding rate is, that is, after sampling, quantizing, and coding the analog signal is completed, the larger the proportion of the useful information part in the data stream is; conversely, the smaller the signal strength, the smaller the corresponding coding rate, i.e. the smaller the proportion of useful information in the data stream after sampling, quantizing and coding the analog signal.
Specifically, the increase of the coding rate may be to increase the sampling rate, or to reduce the useless information and retain more useful information during the coding process, i.e. to reduce the compression ratio, for example, an encoding algorithm that stores 16-bit data of each sample in the audio stream at 4-bit, the compression ratio is 4: 1, 25% of the useful information is retained, and if the compression ratio is changed to 8 bits, the compression ratio is changed to 2:1, the compression ratio is reduced, and 50% of the useful information is retained, more useful information is retained, but the data amount of the audio data becomes larger.
Step S103: and processing the audio data according to the coding rate to obtain processed audio data, and transmitting the processed audio data to the audio playing equipment.
The sizes of the audio data corresponding to different encoding rates are different, and the tone qualities of the audio data are also different. Specifically, the higher the encoding rate, the larger the audio data corresponding thereto, and the lower the encoding rate, the smaller the audio data corresponding thereto. Therefore, after acquiring the encoding rate of the audio data according to the signal strength between the electronic device and the audio playing device, the original audio data may be processed according to the encoding rate to acquire processed audio data, where the original audio data output by the electronic device may be acquired from the local of the electronic device or may be acquired from a server through a network, which is not limited herein, and it is understood that when the encoding rate is higher, the original audio data may not be processed or may be processed to acquire larger processed audio data; when the encoding rate is small, the original audio data is processed to obtain smaller processed audio data.
Furthermore, after the processed audio data are obtained, the processed audio data are transmitted to the audio playing device through the Bluetooth, so that it can be understood that when the signal intensity between the electronic device and the audio playing device is high, the music playing is not easy to be blocked, and the audio data with high coding rate can be transmitted, so as to improve the music experience; when the signal intensity between the electronic device and the audio playing device is small, the music playing is easy to be blocked, and the audio data with low encoding rate can be transmitted to reduce the blockage of the music playing, so that the code rate of the music playing is dynamically adjusted to adapt to the music playing under different signal intensities.
According to the code rate optimization method provided by one embodiment of the application, when the electronic device is connected to the audio playing device through the Bluetooth, the signal intensity between the electronic device and the audio playing device is detected in real time, when the electronic device runs a target application program, the coding rate of audio data corresponding to the signal intensity is obtained in real time, the target application program at least supports the audio data, the audio data is processed according to the coding rate to obtain the processed audio data, and the processed audio data is transmitted to the audio playing device, so that the coding rate of the corresponding audio data is obtained according to the signal intensity between the electronic device and the audio playing device, the audio data is updated according to the coding rate and transmitted, the music playing card pause is reduced, and the music experience is improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a code rate optimization method according to another embodiment of the present application. As will be explained in detail with respect to the flow shown in fig. 3, the method may specifically include the following steps:
step S201: when the electronic equipment is connected to audio playing equipment through Bluetooth, the signal intensity between the electronic equipment and the audio playing equipment is detected in real time.
Step S202: and when the electronic equipment runs the target application program, judging whether the signal intensity is lower than a preset signal intensity or not.
In this embodiment, the electronic device presets and stores a preset signal strength, where the preset signal strength is used as a criterion for detecting the acquired signal strength. It can be understood that, after the signal strength between the electronic device and the audio playing device is obtained, the signal strength is compared with a preset signal strength to determine whether the signal strength is lower than the preset signal strength. As one way, the preset signal strength may represent the signal strength at which the audio data may be normally transmitted.
Step S203: and when the signal intensity is not lower than the preset signal intensity, acquiring the coding rate corresponding to the signal intensity in real time.
When the signal intensity is not lower than the preset signal intensity, the representation shows that the signal intensity between the electronic device and the audio playing device can support normal transmission of audio data, that is, a transmission network between the electronic device and the audio playing device is normal, and the audio data can be normally transmitted, so that the electronic device acquires the encoding rate corresponding to the signal intensity in real time.
Referring to fig. 4, fig. 4 is a flowchart illustrating the step S2301 of the code rate optimization method provided by the embodiment shown in fig. 3. As will be described in detail below with respect to the flow shown in fig. 4, and as will be described in detail below with respect to the flow shown in fig. 3, the method may specifically include the following steps:
step S2301: and when the signal intensity is not lower than the preset signal intensity, acquiring a first distance between the electronic equipment and the audio playing equipment.
Specifically, when the signal strength is not lower than the preset signal strength, a first distance between the electronic device and the audio playing device is obtained, and as a way, the first distance can be calculated by a power control algorithm of a protocol in an inquiry and scanning function in the discovery process of the electronic device. As another way, the first distance may be obtained by converting the signal strength between the electronic device and the audio playback device into a distance between the electronic device and the audio playback device.
Step S2302: obtaining the coding rate based on the first distance and the signal strength, wherein the first distance and the coding rate are inversely related.
In this embodiment, the factors affecting the audio data transmission between the electronic device and the audio playback device include at least the first distance between the electronic device and the audio playback device, in addition to the signal strength. It can be understood that the first distance is inversely related to the encoding rate, that is, in the case that the signal strength between the electronic device and the audio playing device is fixed, when the first distance is longer, the longer the transmission time of the audio data transmitted from the electronic device to the audio playing device is, the more easily the music playing jam occurs; and when the first distance is smaller, the shorter the transmission time of the audio data transmitted from the electronic equipment to the audio playing equipment is, the less music playing jam is likely to occur, so that besides acquiring the encoding rate according to the signal strength between the electronic equipment and the audio playing equipment, the encoding rate can be acquired according to the first distance between the electronic equipment and the audio playing equipment, and the encoding rate can be acquired together according to the two influence factors of the signal strength and the first distance to process the audio data, so as to acquire a better encoding rate and acquire better processed audio data.
Step S204: and processing the audio data according to the coding rate to obtain processed audio data, and transmitting the processed audio data to the audio playing equipment.
Step S205: and when the signal intensity is lower than the preset signal intensity, detecting a second distance between the electronic equipment and the audio playing equipment.
As another mode, when the signal strength is lower than the preset signal strength, it is characterized that the signal strength between the electronic device and the audio playing device is not enough to support normal transmission of audio data, that is, a transmission network between the electronic device and the audio playing device is not normal, an influence factor influencing the signal strength between the electronic device and the audio playing device is detected, specifically, in this embodiment, a second distance between the electronic device and the audio playing device is detected, and a detection method thereof is similar to a detection method of the first distance, and is not described herein again.
Step S206: and judging whether the second distance is greater than a preset distance.
In this embodiment, a preset distance is preset and stored in the electronic device, and the preset distance is used as a criterion for determining the second distance, so that when the second distance between the electronic device and the audio playing device is obtained, the second distance is compared with the preset distance to determine whether the second distance is greater than the preset distance. As one manner, the preset distance may be a bluetooth farthest connection distance, a bluetooth optimal connection distance, or the like, and is not limited herein.
Step S207: and sending prompt information when the second distance is greater than the preset distance, wherein the prompt information is used for prompting a user to reduce the distance between the electronic equipment and the audio playing equipment. It can be understood that, when the second distance is smaller than the preset distance, the influence factor representing the influence on the signal strength of the electronic device and the audio playing device is not the distance between the electronic device and the audio playing device, and then the detection is continued for other influence factors; and when the second distance is greater than the preset distance, the second distance between the electronic device and the audio playing device is characterized to exceed the optimal connection distance or exceed the farthest connection distance, the audio data transmission at the distance is poor, and the second distance can be used as a main influence factor influencing the signal strength of the electronic device and the audio playing device. Thus, the electronic device issues a prompt in response, wherein the prompt may include a voice prompt, a vibration prompt, and/or a text prompt, etc. for prompting the user to decrease the distance between the electronic device and the audio playback device, such as: when the prompt information is text information, the prompt information may be "distance is too large, please reduce the distance", and the like.
Step S208: and acquiring the position information of the electronic equipment and the position information of the audio playing equipment.
Furthermore, a GPS module may be disposed in the electronic device, and a GPS module may also be disposed in the audio playback device, so as to obtain the position information of the electronic device through the GPS module of the electronic device, and obtain the position information of the audio playback device through the GPS module of the audio playback device.
