Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The configuration method of the coding and decoding format can be applied between terminals. The terminal can be a mobile phone, a tablet computer, a wearable device, a wireless headset and the like. For example, the audio codec format between the mobile phone and the tablet computer, the video codec format between the mobile phone and the portable watch, and the audio codec format between the tablet computer and the wireless headset. The above configuration method is described by taking the example of the application to the handset 101 and the wireless headset 102 shown in fig. 1: after the mobile phone 101 is connected to the wireless headset 102, if the user selects the codec format for the wireless headset 102, the mobile phone can set the codec parameters of the codec format selected by the user as the codec parameters supported by the wireless headset 102, so as to obtain the codec format that can be configured to the wireless headset 102, thereby preventing the wireless headset 102 from rejecting the configuration due to the fact that the wireless headset 102 does not support the codec parameters of the codec format configured by the mobile phone 101, improving the configuration success rate of the codec format, and improving the audio interaction efficiency between the mobile phone 101 and the wireless headset 102.
In an embodiment, as shown in fig. 2, a method for configuring a codec format is provided, which is described by taking the method as an example applied to the mobile phone 101 in fig. 1, and includes the following steps:
step S201, acquiring a coding and decoding format selected by a user aiming at an opposite terminal;
illustratively, the user may select one audio codec format from a plurality of audio codec formats supported by the wireless headset 102, and the handset 101 obtains the audio codec format selected by the user.
Further, the mobile phone can also execute the following steps: displaying an interface of the coding and decoding format supported by the opposite terminal; and determining the selected coding and decoding format based on the coding and decoding format selection operation input by the user on the interface.
That is, after the mobile phone 101 is connected to the wireless headset 102, the mobile phone 101 may obtain the audio codec format supported by the wireless headset 102 from the wireless headset 102; if the Audio codec format supported by the wireless headset 102 includes LDAC (one of Audio Coding), aptX (one of Audio Coding), AAC (Advanced Audio Coding), and SBC (Sub-band Coding), the mobile phone 101 may present a selection interface shown in fig. 3 to the user, and the user selects the Audio codec format to be configured for the wireless headset 102 on the selection interface, so as to implement user-defined selection of the Audio codec format by the user.
Step S202, determining target coding and decoding parameters aiming at the selected coding and decoding format from candidate coding and decoding parameters supported by the opposite terminal under different coding and decoding formats;
step S203, setting the target encoding and decoding parameter as the encoding and decoding parameter of the selected encoding and decoding format, to obtain an allocable encoding and decoding format for allocating to the opposite end.
The codec parameters are parameters for performing codec processing on the received data at the opposite end, such as sampling frequency, bit rate, channel mode, and the like during audio codec processing. The audio sampling frequency is the number of samples per second that are extracted from continuous data and constitute discrete data, and can be expressed in hertz (Hz); bit rate, which in the field of telecommunications and computing refers to the number of bits transmitted or processed per unit time; the channel mode may be mono, binaural, etc. The codec parameters supported by the peer end in different codec formats may be different, and exemplarily, the sampling frequency supported by the wireless headset 102 in LDAC is a, and the sampling frequency supported in aptX is b.
For example, if the audio codec format selected by the user is LDAC, the handset 101 may determine the audio codec parameters supported by the wireless headset 102 under LDAC from the audio codec parameters supported by the wireless headset 102 under LDAC, aptX, AAC, and SBC, and set the audio codec parameters of the lacc to the above-mentioned supported audio codec parameters, so as to obtain the audio codec format that can be configured to the wireless headset 102.
Further, the candidate codec parameters are obtained together when the codec format supported by the opposite end is obtained from the opposite end after the candidate codec parameters are connected with the opposite end.
For example, after the mobile phone 101 is connected to the wireless headset 102, the mobile phone may obtain, through a Get Capabilities command of a bluetooth protocol, an audio codec format supported by the wireless headset 102 and audio codec parameters (i.e., candidate codec parameters) supported by the wireless headset in each audio codec format. Therefore, the mobile phone obtains the candidate coding and decoding parameters and the audio coding and decoding format supported by the wireless earphone, so that the extra signaling is avoided from being spent to obtain the candidate coding and decoding parameters, and the interaction efficiency is improved.
In the configuration method of the coding and decoding formats, after the user selects the coding and decoding formats for the opposite terminal, the coding and decoding parameters of the selected coding and decoding formats are set as the coding and decoding parameters supported by the opposite terminal, so that the coding and decoding parameters which are allocated to the opposite terminal and can be matched with the coding and decoding formats are supported by the opposite terminal, the opposite terminal is prevented from rejecting the configuration of the coding and decoding formats, and the success rate of the configuration of the coding and decoding formats and the data interaction efficiency between terminals are improved.
Further, when the mobile phone 101 executes the step S203, the following steps may be further executed: if the selected coding and decoding format carries default coding and decoding parameters, the default coding and decoding parameters are changed into the target coding and decoding parameters, and the configurable coding and decoding format is obtained.
For example, if the LDAC selected by the user carries the default audio codec parameter, the mobile phone 102 may change the default audio codec parameter to the audio codec parameter supported by the wireless headset 102, so as to obtain the LDAC carrying the audio codec parameter supported by the wireless headset 102.
The processing layers passed by the mobile phone 101 in the process of executing the above steps S201 to S203 may be as shown in fig. 4. Specifically, the encoding/decoding format envelope of the mobile phone 101 receives the audio encoding/decoding format supported by the wireless headset and the audio encoding/decoding parameters supported by each audio encoding/decoding format; the encoding and decoding format encapsulation layer transmits the received data to the upper processing layer; the last processing layer transmits the data to an application architecture layer for a user to select an audio coding and decoding format; after the user selects the audio coding and decoding format, the mobile phone 101 can modify the audio coding and decoding parameters at the application architecture layer and transmit the audio coding and decoding parameters to the next processing layer; the next processing layer transmits the modified audio coding and decoding parameters to a coding and decoding format encapsulating layer; sixthly, the codec format envelope forms a configurable audio codec format based on the modified audio codec parameters, and the packet processing is sent to the wireless headset 102.
It can be seen that, in the process of configuring the codec format, there are more processing layers involved, and after the user configures the audio codec format allocated to the wireless headset 102 this time, in order to improve the interaction efficiency between the mobile phone 101 and the wireless headset 102 next time, the mobile phone 101 may record the configurable codec format in the codec format encapsulation layer at the local end.
In the above manner, since the configurable codec format is directly stored in the codec format encapsulation layer, when the mobile phone 101 is connected to the wireless headset 102 next time, the configurable codec format stored in the codec format encapsulation layer can be directly sent to the wireless headset 102, thereby avoiding the above processes from (ii) to (iv), and improving the interaction efficiency between devices.
Further, after the mobile phone 101 executes the above-mentioned codec format envelope layer recording the configurable codec format in the home terminal, the following steps may also be executed: after the connection with the opposite terminal is disconnected, the opposite terminal is connected again, and the recorded configurable coding and decoding formats are packaged in the coding and decoding format packaging layer; and sending the packaged configurable coding and decoding format to the opposite terminal.
In the above manner, the mobile phone 101 can directly pack the recorded configurable codec format in the codec format pack layer and send the packed configurable codec format to the wireless headset 102, so that the interaction efficiency between devices is improved.
Further, when the mobile phone 102 performs the above-mentioned step of recording the configurable codec format in the codec format envelope layer of the home terminal, the following steps may also be performed: and if the feedback that the opposite end agrees to configure the configurable coding and decoding format is received, recording the configurable coding and decoding format in a coding and decoding format encapsulation layer of the local end.
That is to say, when receiving that the wireless headset 102 agrees to the configuration, the mobile phone 101 records the audio codec format of this time in the codec format envelope, so as to avoid recording the audio codec format rejected by the wireless headset 102, which results in failure of the next codec format configuration.
Further, if the connection between the local terminal and the opposite terminal is a Bluetooth connection, the codec format encapsulation layer is a Bluetooth stack layer (Bluetooth stack) of the Bluetooth protocol architecture as shown in fig. 5. The Bluetooth system service and the HAL (hardware abstraction layer) interact through JNI (Java Native Interface, Java local Interface program), the HAL and the Bluetooth stack layer interact, and the Bluetooth stack layer and the supplier extension layer also interact.
An application (App) on the handset may provide the user with the selection interface shown in fig. 3; the application framework layer can acquire audio coding and decoding parameters supported by the wireless headset 102 in each audio coding and decoding format through a bluetooth protocol flow, and replace the default audio coding and decoding parameters of the mobile phone system with the audio coding and decoding parameters supported by the wireless headset 102; the Bluetooth Stack can record the set audio coding and decoding format in the Bluetooth Stack after the audio coding and decoding format is successfully set, and directly adjusts the audio coding and decoding format to the highest priority when the Bluetooth Stack is connected with the wireless earphone 102 next time, and sends the audio coding and decoding format to the wireless earphone 102, so that the interaction efficiency is improved.
In order to better understand the above method, an application example of the configuration method of the codec format of the present application is described in detail below. The application example is as follows: the mobile phone configures an audio coding and decoding format for the wireless earphone, and the mobile phone is connected with the wireless earphone through Bluetooth.
The mobile phone and the wireless headset can perform bluetooth data interaction based on A2DP (advanced Audio Distribution Profile, bluetooth stereo Audio transmission specification). In the protocol flow of A2DP, Get Capabilities is a Bluetooth command for obtaining an audio codec format supported by an opposite terminal and corresponding audio codec parameters; set Configuration is a bluetooth command to Set the audio codec format for the peer.
The application example modifies the audio coding and decoding parameters carried in the audio coding and decoding format of the mobile phone end while setting the audio coding and decoding format so as to ensure that the opposite end does not reject the audio coding and decoding format set by the mobile phone end.
Specifically, as shown in fig. 6 and fig. 3, in the present application example, a selection interface of an audio codec format supported by a wireless headset is presented to a user through an App of a mobile phone android system; the application framework layer may replace the default audio codec parameters of the mobile phone system with the audio codec parameters supported by the wireless headset 102 through the bluetooth protocol flow, and then send a Set Configuration command to the wireless headset.
The application example can also store the audio coding and decoding format set by the user at this time based on the Bluetooth stack of the android system; when the mobile phone is connected with the wireless earphone next time, the audio coding and decoding format stored by the Bluetooth stack can be directly configured for the wireless earphone. As shown in fig. 7, the specific steps include the following:
the mobile phone and the wireless earphone exchange audio coding and decoding formats supported by each other and corresponding audio coding and decoding parameters; a user can select an audio coding and decoding format supported by the wireless headset through the mobile phone App; the mobile phone modifies the parameters of the audio coding and decoding format selected by the user into audio coding and decoding parameters supported by the wireless earphone and configures the parameters to the wireless earphone; after receiving the configuration, the wireless earphone feeds back the agreement of the configuration to the mobile phone.
After the mobile phone determines that the wireless earphone feedback agrees with the configuration, the audio coding and decoding format of the configuration is recorded in a configuration file of a Bluetooth stack, and the Bluetooth connection with the wireless earphone is disconnected.
After the mobile phone is reconnected with the wireless earphone, the audio coding and decoding formats supported by the mobile phone and the wireless earphone and the corresponding audio coding and decoding parameters are exchanged with each other again; the mobile phone configures the audio coding and decoding format in the configuration file of the Bluetooth stack to the wireless earphone; after receiving the configuration, the wireless earphone feeds back a message agreeing with the configuration to the mobile phone.
In the application example, after the audio coding and decoding format of the wireless earphone is set by the user through the mobile phone, the last audio coding and decoding format is used by default when the wireless earphone is connected next time, the user does not need to set again, user operation is reduced, and the interaction efficiency between the mobile phone and the wireless earphone is improved.

The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
