Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for controlling a bluetooth headset according to an embodiment of the present disclosure.
The specific steps may include:
s101: receiving an audio data packet and determining a data code rate corresponding to the audio data packet;
the present embodiment may be applied to a processor (e.g., a micro control unit MCU) of a bluetooth headset, and when the bluetooth headset includes a left headset and a right headset, the present embodiment may be applied to a processor of a main headset in the left headset and the right headset. The Bluetooth headset can be connected with master control equipment such as a smart phone and a tablet personal computer, and the master control equipment can transmit an audio data packet to the Bluetooth headset through Bluetooth.
After the bluetooth headset receives the audio data packet, the bluetooth headset can perform encoding and decoding operations on the audio data packet to obtain a data code rate corresponding to the audio data packet. Specifically, the host device may transmit multiple frames of audio data packets to the bluetooth headset, and the bluetooth headset determines a data rate of each frame of audio data packet.
As a possible implementation manner, before determining the audio quality mode of the bluetooth headset according to the data code rate, a code rate control mode of the bluetooth headset may also be determined, where the code rate control mode includes a fixed code rate mode and an adaptive code rate mode, the code rate of encoding and decoding in the fixed code rate mode is a fixed value such as 990kbps, 660kbps, and the like, and the code rate of encoding and decoding in the adaptive code rate mode is adaptively adjusted according to a retransmission rate. Correspondingly, if the code rate control mode of the bluetooth headset is the fixed code rate mode, the steps of S102 and S103 in this step are entered: if the code rate control mode of the Bluetooth headset is the self-adaptive code rate mode, the main control equipment can adjust the data code rate according to the retransmission rate.
S102: determining an audio quality mode of the Bluetooth headset according to the data code rate, and determining a scanning strategy corresponding to the audio quality mode;
in this step, the current audio quality mode of the bluetooth headset can be determined according to the data code rate; as a possible implementation manner, the audio quality mode of the bluetooth headset may be determined according to the data code rate of the current frame of audio data, or may be determined according to the data code rate of the most recent multi-frame of audio data.
Specifically, the audio quality mode of the bluetooth headset may include a normal mode and a high fidelity mode, and in the normal mode, the scanning policy is to start a page scan function of the bluetooth headset; in the high fidelity mode, the scanning strategy can be further determined by combining the Bluetooth connection state.
S103: and starting or closing the page scan function of the Bluetooth headset according to the scanning strategy.
After receiving the audio data packet, the embodiment determines the data code rate of the audio data packet, and then determines the current audio quality mode of the bluetooth headset according to the data code rate. The bluetooth headset opens the page scan function and can occupy certain data transmission bandwidth, and this embodiment determines the corresponding scanning strategy according to the audio quality mode, and then opens or closes the page scan function of bluetooth headset according to the scanning strategy to avoid appearing leading to the bluetooth headset to broadcast the condition that the audio frequency card pauses because of opening the page scan function. Therefore, the embodiment can reduce the pause phenomenon when the Bluetooth headset plays audio, and improve the audio playing quality.
As a further introduction to the corresponding embodiment of fig. 1, the audio quality mode of a bluetooth headset may be determined by: determining the size relation between the data code rate of the audio data packet and the threshold code rate; if the data code rate of the current frame audio data packet is less than or equal to the threshold code rate, judging that the audio quality mode of the Bluetooth headset is a common mode; and if the data code rates of the continuous N frames of audio data packets including the current frame are all larger than the threshold code rate, judging that the audio quality mode of the Bluetooth headset is a high-fidelity mode.
Specifically, before determining the audio quality mode of the bluetooth headset according to the data code rate, an expected code rate set by a user may also be determined, and a product of the expected code rate and a preset coefficient a is set as the threshold code rate; a is more than 0 and less than 1. For example, if the user's desired bitrate is 990kbps and a is 0.8, the threshold bitrate is 792kbps.
As a further introduction to the corresponding embodiment of fig. 1, the bluetooth headset includes a master headset and a slave headset, and the scanning policy may be determined in at least the following two ways.
The first method is as follows: determining the scanning strategy according to the audio quality mode and the Bluetooth connection state; wherein the Bluetooth connection state describes whether the master earphone and the slave earphone establish Bluetooth connection.
The scanning strategy is specifically as follows:
if the audio quality mode is a high fidelity mode and the Bluetooth connection between the master earphone and the slave earphone is established, generating the scanning strategy for closing the page scan function;
if the audio quality mode is a high-fidelity mode and the Bluetooth connection between the master earphone and the slave earphone is not established, generating the scanning strategy for starting the page scan function;
if the audio quality mode is a common mode and the Bluetooth connection between the master earphone and the slave earphone is established, generating the scanning strategy for starting the page scan function;
if the audio quality mode is a common mode and the Bluetooth connection between the master earphone and the slave earphone is not established, generating the scanning strategy for starting the page scan function;
and the data code rate of the Bluetooth headset in a normal mode is lower than that of the Bluetooth headset in a high-fidelity mode.
The second method comprises the following steps: judging whether the master earphone establishes Bluetooth connection with the slave earphone; if not, generating the scanning strategy for starting the page scan function; if yes, determining the audio quality mode of the Bluetooth headset according to the data code rate, and determining a scanning strategy corresponding to the audio quality mode according to the following rules: if the audio quality mode is a high fidelity mode, generating the scanning strategy for closing the page scan function; if the audio quality mode is a common mode, generating the scanning strategy for starting a page scan function; and the data code rate of the Bluetooth headset in a normal mode is lower than that of the Bluetooth headset in a high-fidelity mode.
The flow described in the above embodiment is explained below by an embodiment in practical use.
The TWS headset can connect two handsets simultaneously while maintaining 3 ACL links: one ACL link is arranged between the master earphone and the slave earphone, and one ACL link is arranged between the two mobile phones. The BLE broadcasting is also carried out in normal service, and some characteristics are adapted to the mobile phone. The code rate of the Audio data packet received by the bluetooth headset is determined by the mobile phone, the parameter information is not available in the A2DP (Advanced Audio Distribution Profile, bluetooth Audio transmission model protocol) process, and the mobile phone can dynamically adjust the code rate in the playing process. In general, the mobile phone can set the code rates to 990kbps, 660kbps, 330kbps and adaptive code rates, wherein the first three code rates are fixed code rates, and the adaptive code rate is a code rate which is adjusted by the mobile phone in time according to the retransmission rate.
The bandwidth of the bluetooth headset itself is limited, and both dual connectivity and BLE broadcasting are required, and the bandwidth reserved for audio data transmission is fixed. Playing a high definition audio codec in such a scenario is substantially easy to jam, especially at a code rate of 990kbps, substantially no scenario can be used. The slight interference of the dual connection scene code rate of 660kbps can cause jamming, and the user experience is seriously influenced.
In order to solve the stuck phenomenon in the TWS headset, an embodiment of the present application provides a scheme for reducing stuck when playing with high definition audio codec in a music service state. This scheme is providing the in-process of high tone quality audio frequency with high code rate, and the scanning strategy is adjusted in good time, reduces the card and pause the condition and takes place to greatly promote user experience.
In a high-audio coding and decoding music playing scene, the TWS earphone can obtain a data code rate corresponding to each audio data packet in the process of unpacking each frame of audio data packet, and if the data code rate is lower than a Threshold code rate Threshold (for example, 600kbps, which can be adjusted according to actual requirements), it is determined that the current mode is a normal (normall) mode. And when the continuous 50 frames (frames) are all larger than the threshold code rate, judging that the current mode is a high fidelity (HD) mode. When the TWS headset detects that the normal mode is switched to the high fidelity mode or the high fidelity mode is switched to the normal mode, a scanning strategy (namely a page scan strategy) is triggered. For the adaptive code rate scenario, the mobile phone will adjust the code rate in real time, and basically no jamming occurs, and the jamming mostly occurs in the scenario of setting a fixed code rate, such as 660kbps or 990kbps. And if the 50 frames are continuously detected to be larger than the code rate threshold, judging that the current scene is a continuous high code rate scene, and triggering an updating scanning strategy.
After the Page scan function is started, the TWS headset needs to reserve a certain time slot to monitor a Page data packet (reconnection request), and the mobile phone or the ear can be successfully reconnected when the Page scan function is started. The Page scan close scenario is against the ear (i.e., another TWS headset) or the handset cannot succeed in reconnecting. Adding a strategy in the page scan strategy: and when the earphone is in the high fidelity mode and the Bluetooth connection is established, closing the page scan function. This strategy does not affect master-slave loopback: when the Bluetooth connection between the master earphone and the slave earphone is not established, the page scan is started, and the master earphone and the slave earphone can be connected back successfully. In the process, the Bluetooth connection is established between the master earphone and the slave earphone, and the page scan function is closed in a high fidelity mode, more bandwidth is reserved for downlink audio data transmission in the scene, and other mobile phones cannot be connected with the earphones, so that the blocking condition under high code rate is greatly reduced, and the user experience is optimized.
Referring to fig. 2, fig. 2 is a flow chart of determining an audio quality mode according to an embodiment of the present application, which illustrates a process as follows:
s201: playing music;
s202: setting the audio quality mode to be a common mode, and resetting a counter;
s203: acquiring a code rate;
s204: judging whether the code rate is less than or equal to a code rate threshold or not; if yes, go to S205; if not, entering S207;
s205: judging whether the current mode is a common mode or not; if yes, entering S203; if not, the process goes to S206;
s206: setting the audio quality mode to be a common mode, and resetting a counter;
s207: judging whether the current mode is a high fidelity mode; if yes, entering S203; if not, entering S208;
s208: the value of the counter is increased by 1;
s209: judging whether the value of the counter exceeds 50; if yes, entering S210; if not, the step S203 is entered;
s210: the audio quality mode is set to high fidelity mode and the counter is cleared.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating a scanning policy determination principle provided in an embodiment of the present application, where in an audio quality mode, a normal mode is switched to a hi-fi mode, or the normal mode is switched to the hi-fi mode, a scanning policy is triggered, and if a TWS headset is in the hi-fi mode and a bluetooth connection is established, a page scan function is turned off; if the TWS earphone is in the high-fidelity mode and the Bluetooth connection is not established, starting a page scan function; if the TWS earphone is in a common mode and Bluetooth connection is established, starting a page scan function; and if the TWS earphone is in the normal mode and the Bluetooth connection is not established, starting the page scan function.
In the process of providing high-tone-quality audio at a high code rate, the scanning strategy is timely adjusted, and the occurrence of the blockage situation is reduced. After the scheme is introduced, the data retransmission rate of a high-code-rate scene is reduced to 6% from 10%, and basically no blockage exists in a single ACL connection 990kbps in a common use scene, so that the user experience is greatly improved.
