Based on the hardware structure, various embodiments of the method of the invention are provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a bluetooth audio transmission adjustment method according to a first embodiment of the present invention, in which the method includes:
step S10, detecting the data volume of the Bluetooth resource pool in real time during the Bluetooth transmission process with the Bluetooth audio sending end, and judging whether the data volume of the Bluetooth resource pool is less than a first preset data volume corresponding to the pause early warning;
step S20, when the data volume of the Bluetooth resource pool is smaller than a first preset data volume corresponding to the pause early warning, the power of the Bluetooth chip is increased;
bluetooth audio frequency sending end includes smart mobile phone, computer, intelligent wrist-watch etc. in this embodiment, and the user can use bluetooth function to be connected smart mobile phone and smart television, and the user can click the broadcast music on smart mobile phone after the bluetooth is connected to broadcast data transmission to smart television through the bluetooth, this kind of technique can be said as the bluetooth and listen alone. However, due to many factors such as power, transmission distance, insufficient online sound source resources, and network interference in the 2.4Ghz band of the bluetooth device, a katon phenomenon often occurs when the bluetooth device is used to listen to songs, which affects normal playing of music.
In this embodiment, it is described by taking an example that the bluetooth audio transmitting end is a smart phone, when the smart phone and the smart tv perform bluetooth transmission, when the data amount of the bluetooth resource pool of the smart tv reaches a preset play data amount, music starts to be played, the preset play data amount may be set to K × MinUnitBuffer, where the default value of K is 4, and MinUnitBuffer is a preset minimum unit play data amount, where MinUnitBuffer may be calculated according to a formula, and the calculation formula is:
MinUnitBuffer (AF _ Frame _ Cnt × Sample _ Rate/AF _ Sample _ Rate +4) × MinBufferCnt, where AF _ Frame _ Cnt is the number of frames of a hardware device processing a single data block, and the default value is 1024; sample _ Rate is a sampling Rate configured by the hardware equipment, and the default value is 44100; M-inBufferCnt is the number of software resource pools, the minimum value is 2, and when minBufCount is less than 2, the value of minBufCount is 2; MinUnitBuffer is a preset minimum unit play data volume, and the default value (1024 × 44100/48000+4) × 2 is 1888byte from the above parameters.
In this embodiment, the preset play data amount may be set to K × MinUnitBuffer, and in fact, when the value of K is greater than or equal to 1, the available data amount in the bluetooth resource pool may also be maintained to be normally played, but in order to avoid the beginning of play from being blocked, the value of K is set to 4, so that the data amount in the bluetooth resource pool is relatively sufficient, and even if the data transmission is affected by external interference in the bluetooth transmission process, the data amount in the bluetooth resource pool is enough at this time, and the blocking phenomenon may not occur immediately. Thereby can take and predetermine in advance whether bluetooth transmission is about to block and reduce the appearance of blocking and pause the phenomenon, specifically, the in-process that the smart TV carries out bluetooth transmission with bluetooth audio frequency sending end, real-time detection bluetooth resource pond data volume whether is less than the first preset data volume that the blocking corresponds, when detecting that bluetooth resource pond data volume is less than the first preset data volume that the early warning of blocking and pause corresponds, thereby can increase bluetooth chip's power earlier and improve bluetooth resource pond data volume. It should be noted that the adjustment of the power of the bluetooth chip of the smart television is a dynamic process, that is, the power is not directly statically increased to a fixed value before starting like in the prior art, but the power of the bluetooth chip is adaptively adjusted by the smart television according to the data volume condition of the actually played bluetooth resource pool, so that the data volume of the bluetooth resource pool meets the requirement of not being jammed in playing. Further, the first preset number corresponding to the pause early warning can be set to 2 minunitbuffers, which can be understood as that the data size of the bluetooth resource pool is about to be reduced to a critical value, wherein the critical value is MinUnitBuffer, and when the data size of the bluetooth resource pool is less than 2 minunitbuffers, a pause phenomenon may be about to occur, so that the power of the bluetooth chip needs to be increased to increase the data size of the bluetooth resource pool. Whether jamming is to occur or not is judged in advance in the Bluetooth transmission process, when the fact that the data volume of the Bluetooth resource pool is smaller than the range of 2MinUnitBuffer is detected, the power of the Bluetooth chip is increased, the data volume of the Bluetooth resource pool is increased, the jamming phenomenon caused by insufficient data volume of the Bluetooth resource pool is avoided, through judging the jamming in advance, the power of the Bluetooth chip is increased when the early warning condition of the jamming of the Bluetooth chip is achieved, flexible early warning is achieved, the power consumption of the Bluetooth chip is increased to a fixed value before starting, and the whole power consumption can be reduced.
Step S30, when the power of the Bluetooth chip is increased to the preset maximum power and the data volume of the Bluetooth resource pool is still less than the first preset data volume, the Bluetooth sending end is triggered to reduce the audio quality of the Bluetooth transmission.
In this embodiment, if the power of the bluetooth chip has been increased to the preset maximum power, and the data size of the bluetooth resource pool is still smaller than the first preset data size at this time, where the first preset data size is 2MinUnitBuffer, the data size of the bluetooth resource pool is still insufficient at this time, and jamming is likely to occur, in order to reduce the occurrence of the jamming phenomenon, the data size of the bluetooth resource pool also needs to be increased, but the power of the bluetooth chip has been increased to the maximum at this time, and cannot be increased continuously, so that the data size of the bluetooth resource pool can be increased by triggering the bluetooth sending end to reduce the audio quality of bluetooth transmission. The available data volume of the resource pool can be improved by reducing the audio quality of the Bluetooth transmission, and although the audio quality is reduced, the phenomenon of pause can be avoided by properly reducing the audio quality for a user, and the user can receive the adjustment mode. The data volume of the Bluetooth resource is improved by increasing the power of the Bluetooth chip, and when the Bluetooth chip cannot be adjusted again, the data volume of the Bluetooth resource pool can be improved by reducing the audio quality of Bluetooth transmission, so that the phenomenon of blocking is effectively reduced.
Further, a second embodiment of the bluetooth audio transmission adjusting method according to the present invention is proposed based on the first embodiment of the bluetooth audio transmission adjusting method according to the present invention, and in this embodiment, the step of increasing the power of the bluetooth chip in step S20 includes:
step S11, determining a first initial value to be adjusted according to the power of the Bluetooth chip, and adjusting the first initial value as a first power parameter value;
step S12, during the adjustment process, the first power parameter value is accumulated with a preset adjustment step length to update the first power parameter value, and the power of the Bluetooth chip is adjusted according to the latest first power parameter value.
In this embodiment, two ways of increasing the power of the bluetooth chip may be adopted, that is, the power of the bluetooth chip is increased by adjusting the power coefficient or the power of the bluetooth chip is directly increased, specifically, the first way is to obtain the power coefficient through calculation, and then further determine the power of the bluetooth chip by the power coefficient, so as to call the driving interface to set the power of the bluetooth chip; the second mode can directly set power, and further calls a driving interface to set the power of the Bluetooth chip. That is, the first power parameter may be power of the bluetooth chip, and may also be a power coefficient corresponding to the power.
The first mode is specifically as follows: through transferring bluetooth drive interface, read bluetooth chip's power Q, substitute bluetooth power computational formula with bluetooth chip's power and calculate the power coefficient that bluetooth chip's power corresponds, wherein bluetooth power computational formula is: and Q is P multiplied by MaxCapity, wherein Q is the power of the Bluetooth chip, P is a power coefficient, MaxCapity is the maximum power value of the Bluetooth chip, the value range of the power coefficient is more than or equal to 0.4 and less than or equal to 1, and the MaxCapity default value is 20dBm, namely 0.1 w. For example, calling a bluetooth driver interface, reading that the power Q of a bluetooth chip is 0.09w, calculating a power coefficient P to be 0.9 according to a formula, where the power coefficient is smaller than 1, and the power coefficient may also be increased by 0.1 to increase the power of the bluetooth chip, where a first initial value to be adjusted is 0.09, adjusting 0.09 as a first power parameter value, and accumulating 0.09 by a preset step size to update the first power parameter value, where the preset step size is 0.1 × 0.1 — 0.01w (where 0.1 is an adjustment step size of the power coefficient and 0.1 is a default value of MaxCapacity), the updated first power parameter value is 0.1w, the power corresponding to the first power parameter value is 0.1w, and calling the driver interface sets the power of the bluetooth chip to 0.1 w. The second mode is specifically as follows: the power value range of the Bluetooth chip is more than or equal to 0.04 and less than or equal to 0.1, the power of the Bluetooth chip is read to be 0.08 by calling the Bluetooth driving interface, the power at the moment is not the maximum value, the power of the Bluetooth chip can be continuously increased, the first initial value is 0.08, 0.08 is used as a first power parameter value for adjustment, 0.08 is accumulated by a preset adjustment step length to update the first power parameter value, the preset adjustment step length at the moment is 0.01w, the updated first power parameter value is 0.09w, the power corresponding to the first power parameter value is 0.09w, and the driving interface is called to set the power of the Bluetooth chip to be 0.09 w.
In the process of dynamically adjusting the power of the bluetooth chip in this embodiment, the first power parameter value is accumulated by the preset adjustment step length to update the first power parameter value, and then the power of the bluetooth chip is adjusted according to the latest first power parameter value, so that the dynamic increase of the power of the bluetooth chip is realized, and the occurrence of a pause phenomenon caused by insufficient data volume of the bluetooth resource pool can be reduced.
Further, after step S12, the method further includes:
step S13, judging whether the Bluetooth resource pool data volume after adjusting the power of the Bluetooth chip is smaller than the first preset data volume;
step S14, if yes, judging whether the latest first power parameter value reaches a preset maximum power parameter value corresponding to the preset maximum power;
step S15, when the latest first power parameter value does not reach the preset maximum power parameter value, return to the step S12 of accumulating the first power parameter value by a preset adjustment step size to update the first power parameter value.
In this embodiment, it is determined whether the amount of the bluetooth resource pool data after adjusting the power of the bluetooth chip is smaller than a first preset data amount, where the first preset data amount is 2MinUnitBuffer, when the amount of the bluetooth resource pool data is smaller than 2MinUnitBuffer, the amount of the bluetooth resource pool data is still insufficient, the power of the bluetooth chip still needs to be increased to increase the amount of the bluetooth resource pool data, but it needs to be determined whether the latest first power parameter value reaches a preset maximum power parameter value corresponding to a preset maximum power, for example, the power Q of the bluetooth chip is read to be 0.09w, the power coefficient P is calculated to be 0.9 according to a formula, the power coefficient at this time is smaller than 1, and the power coefficient can also be increased by 0.1 to increase the power of the bluetooth chip, at this time, the first initial value to be adjusted is 0.09, 0.09 is adjusted as the first power parameter value, the first power parameter value is adjusted, and the step size is accumulated and preset, the preset step length is 0.1 × 0.1 ═ 0.01w (where 0.1 is the adjustment step length of the power coefficient, and 0.1 is the default of MaxCapacity), the updated first power parameter value is 0.1w, the power of the bluetooth chip is set to 0.1w by calling the driving interface, at this time, the data volume of the bluetooth resource pool is less than 2MinUnitBuffer, but the latest first power parameter value, namely 0.1w, reaches the maximum power parameter value, the power of the bluetooth chip can not be increased any more, and the data volume of the bluetooth resource pool can be increased by triggering the bluetooth sending end to reduce the audio quality of bluetooth transmission.
In this embodiment, a first initial value to be adjusted is determined according to the power of a bluetooth chip, the first initial value is used as a first power parameter value, the first power parameter value is accumulated to preset an adjustment step length to update the first power parameter value, the power is adjusted according to the latest first power parameter value, and whether the data volume of a bluetooth resource pool after the power of the bluetooth chip is adjusted is smaller than a first preset data volume or not is judged; if not, the power of the Bluetooth chip can not be increased, and the data volume of the Bluetooth resource pool can be adjusted by triggering the Bluetooth sending end to reduce the audio quality of Bluetooth transmission. The method of increasing the power of the Bluetooth chip is firstly adopted, and if the data volume of the Bluetooth resource pool is sufficient, the audio quality does not need to be reduced, and the audio quality can be ensured. Therefore, dynamic increase of power of the Bluetooth chip is realized, and the data volume of the Bluetooth resource pool is increased by combining a mode of reducing the audio quality of Bluetooth transmission, so that the phenomenon of blocking caused by insufficient data volume of the Bluetooth resource pool can be avoided.
Under normal conditions, the power of the Bluetooth chip is in a direct proportion relation with the data volume of the Bluetooth resource pool, when the power of the Bluetooth chip is increased, the data volume of the Bluetooth resource pool is increased, whether the power of the Bluetooth chip has an increased space or not is judged, and when the power of the Bluetooth chip has the increased space, the data volume of the Bluetooth resource pool can be increased by increasing the power of the Bluetooth chip; in addition, the audio quality of the Bluetooth transmission is in inverse proportion to the data volume of the Bluetooth resource pool, and when the power of the Bluetooth chip is the maximum value, the audio quality of the Bluetooth transmission can be reduced, so that the data volume of the Bluetooth resource pool is improved. The data volume of the Bluetooth resource pool is improved by increasing the power of the Bluetooth chip and then reducing the audio quality of Bluetooth transmission, so that the phenomenon of pause is avoided, and music can be played normally.
Further, a third embodiment of the bluetooth audio transmission adjusting method according to the present invention is provided based on the first embodiment of the bluetooth audio transmission adjusting method according to the present invention, and in this embodiment, the step of triggering the bluetooth sending end to reduce the quality of the bluetooth audio transmitted by the bluetooth sending end in step S30 includes:
and step S300, triggering the Bluetooth sending end to reduce the value of the bit pool parameter so as to reduce the size of the unit frame.
In this embodiment, a mode of reducing a bit pool parameter Value (BitPool Value) may be adopted to reduce the size of a unit frame, so as to reduce audio quality of bluetooth transmission, where a Value range of the bit pool parameter Value is 2 to 250, specifically, the smart television sends an instruction for reducing the audio quality of the bluetooth transmission to the bluetooth sending end, and the bluetooth sending end reduces a current bit pool parameter Value to a default bit pool parameter Value after receiving the instruction, where the default bit pool parameter Value may be set to 19, and reduces the bit pool parameter Value to reduce the size of the unit frame, although audio quality is reduced, when a bluetooth link occupies the same resource, the number of data packets sent in unit time may be increased, and playable audio stream resources with more duration may be obtained, thereby avoiding card pause.
Further, a fourth embodiment of the bluetooth audio transmission adjusting method according to the present invention is provided based on the first embodiment of the bluetooth audio transmission adjusting method according to the present invention, and in this embodiment, after the step of triggering the bluetooth sending end to reduce the quality of the bluetooth audio transmitted by the bluetooth sending end in step S30, the method further includes:
step S31, when the data size of the bluetooth resource pool is greater than or equal to the second preset data size and the preset duration continues, executing the following steps:
and reducing the power of a Bluetooth chip, and triggering the Bluetooth sending end to improve the audio quality of Bluetooth transmission, wherein the second preset data volume is greater than the first preset data volume.
In this embodiment, when the data amount of the bluetooth resource pool is greater than or equal to the second preset data amount and the preset duration is maintained, the power of the bluetooth chip is reduced, the power consumption of the bluetooth module, which is inevitably increased due to the increase of the power of the bluetooth chip, is increased, and then the power consumption of the whole device is increased, and when the data amount of the bluetooth resource pool is sufficient and is maintained in a relatively stable state, the power consumption of the bluetooth module can be reduced by appropriately reducing the power of the bluetooth chip, so that the power consumption of the whole device can be reduced, wherein the second preset data amount is 3MinUnitBuffer, and the preset duration can be set to 1.2 s. Specifically, when the data size of the bluetooth resource pool is greater than or equal to 3MinUnitBuffer and the duration is 1.2s, it indicates that the data size of the bluetooth resource pool is sufficient and in a stable state, and at this time, the power of the bluetooth chip can be reduced, so that the power consumption of the whole device is reduced. When the data volume of the Bluetooth resource pool is sufficient and maintains a stable state, the audio quality of Bluetooth transmission can be properly improved, the available data volume of the resource pool is sufficient and has no pause phenomenon, and the audio quality is ensured as far as possible on the premise of ensuring the smoothness of the audio transmission of the Bluetooth.
Further, before the step of triggering the bluetooth sending end to improve the audio quality of bluetooth transmission in step S31, the method further includes:
s32, when the power of the Bluetooth chip is reduced to the preset minimum power and the data volume of the Bluetooth resource pool is still larger than the second preset data volume, executing the following steps: and triggering the Bluetooth sending end to improve the audio quality of Bluetooth transmission.
In this embodiment, when the power of the bluetooth chip is reduced to the preset minimum value, the data amount of the bluetooth resource pool is still greater than the second preset data amount, where the second preset data amount is 3MinUnitBuffer, which indicates that the data amount of the bluetooth resource pool is sufficient at this time, there is no stuck phenomenon at this time, the data amount of the bluetooth resource pool is not rapidly reduced due to power reduction, and only when the data amount of the bluetooth resource pool is less than the first preset data amount (2MinUnitBuffer), there is a possibility of the stuck phenomenon occurring, and when the data amount of the bluetooth resource pool is sufficient, the audio quality of bluetooth transmission can be properly improved, and the requirement of listening to songs of a user is met, so that the bluetooth sending end is triggered to improve the audio quality of bluetooth transmission, and the audio quality is guaranteed as much as possible on the premise of ensuring smooth bluetooth transmission audio.
Further, the step of reducing the power of the bluetooth chip in step S31 includes:
step S33, determining a second initial value to be adjusted according to the power of the Bluetooth chip when the duration reaches the preset duration, and adjusting the second initial value as a second power parameter value;
step S34, during the adjustment process, subtracting the preset adjustment step size from the second power parameter value to update the second power parameter value, and adjusting the power of the bluetooth chip according to the latest second power parameter value.
In this embodiment, a second initial value to be adjusted is determined according to the power of the bluetooth chip when the duration reaches the preset time, for example, the power of the bluetooth chip when the duration reaches the preset duration is 0.09w, and a second power parameter value is 0.09w, and two ways may be adopted for reducing the power of the bluetooth chip, where the first way is to obtain a power coefficient through calculation, and then further determine the power by the power coefficient, so as to call the driving interface to set the power of the bluetooth chip; the second mode can directly set different powers, and further calls a driving interface to set the power of the Bluetooth chip. I.e. the second power parameter value is also of the same type as comprised by the first power parameter value.
The first mode is specifically as follows: through transferring bluetooth drive interface, read bluetooth chip's power Q, substitute bluetooth power computational formula with bluetooth chip's power and calculate the power coefficient that bluetooth chip's power corresponds, wherein bluetooth power computational formula is: and Q is P multiplied by MaxCapity, wherein Q is the power of the Bluetooth chip, P is a power coefficient, MaxCapity is the maximum power value of the Bluetooth chip, the value range of the power coefficient is more than or equal to 0.4 and less than or equal to 1, and the MaxCapity default value is 20dBm, namely 0.1 w. For example, when the bluetooth driver interface is called, the power Q of the bluetooth chip is read to be 0.09w, the power coefficient P is calculated to be 0.9 according to a formula, the power coefficient may also be reduced, at this time, the second initial value to be adjusted is 0.09, 0.09 is adjusted as the second power parameter value, the preset step size is cumulatively decreased by 0.09 to update the second power parameter value, where the preset step size is 0.1 × 0.1 — 0.01w (where 0.1 is the adjustment step size of the power coefficient, and 0.1 is the default value of MaxCapacity), the updated second power parameter value is 0.08w, the power corresponding to the second power parameter value is 0.08w, and the drive interface is called to set the power of the bluetooth chip to be 0.08 w.
The second mode is specifically as follows: the power value range of the Bluetooth chip is more than or equal to 0.04 and less than or equal to 0.1, the power of the Bluetooth chip is read to be 0.08 by calling the Bluetooth driving interface, the power at the moment is not the minimum value, the power of the Bluetooth chip can be further reduced, the second initial value is 0.08w, 0.08w is used as the second power parameter value for adjustment, the preset adjustment step length is accumulated and reduced by 0.08w to update the second power parameter value, the preset adjustment step length at the moment is 0.01w, the updated first power parameter value is 0.07w, the power corresponding to the second power parameter value is 0.07w, and the driving interface is called to set the power of the Bluetooth chip to be 0.07 w.
In the process of reducing the power of the bluetooth chip in this embodiment, the second power parameter value is subtracted to preset the adjustment step length and the power of the bluetooth chip is adjusted according to the latest second power parameter value after the second power parameter value is updated, in this embodiment, under the condition that the data volume of the bluetooth resource pool is stable and the available data volume is sufficient, the power of the bluetooth chip is appropriately and dynamically reduced, the power consumption of the bluetooth module can be reduced, and thus, the power consumption of the whole bluetooth module can be reduced.
Further, after step S34, the method further includes:
step S35, comparing the resource pool data volume after adjusting the power of the Bluetooth chip with a second preset data volume;
step S36, when the data volume of the Bluetooth resource pool is equal to the second preset data volume, stopping reducing the power of the Bluetooth chip;
step S37, when the data volume of the Bluetooth resource pool is larger than the second preset data volume, judging whether the latest second power parameter value reaches a preset minimum power parameter value corresponding to a preset minimum power; if not, returning to the step of subtracting the preset adjustment step size from the second power parameter value to update the second power parameter value in step S34.
In this embodiment, the bluetooth resource pool data volume after the power of the bluetooth chip is reduced is compared with a second preset data volume, where the second preset data volume may be set to 2MinUnitBuffer, and when the bluetooth resource pool data volume is equal to 2MinUnitBuffer, the power of the bluetooth chip may not be reduced any more, and if the power of the bluetooth chip is reduced continuously, the bluetooth resource pool data volume may be insufficient, so the power of the bluetooth chip is stopped being reduced; when the data amount of the bluetooth resource pool is greater than 2MinUnitBuffer, the data amount of the bluetooth resource pool is sufficient at this time, the power of the bluetooth chip may be continuously reduced, so as to reduce the power consumption of the bluetooth module, but it is necessary to determine whether the latest second power parameter value reaches a preset minimum power parameter value corresponding to a preset minimum power at this time, for example, when the data amount of the current bluetooth resource pool is greater than 2MinUnitBuffer, the power Q of the bluetooth chip is read to be 0.06w, the power coefficient P is calculated to be 0.6 according to a formula, the power coefficient at this time is greater than the minimum power coefficient 0.4, the step of accumulating the preset adjustment step length by the second power parameter value may be continuously returned to update the second power parameter value, for example, the second initial value to be adjusted is 0.06w, 0.06w is adjusted as the second power parameter value, the preset step of accumulating the preset step length by 0.w to update the second power parameter value, wherein the preset step length is 0.1 × 0.01w (where 0.1 is the adjustment step length of the power coefficient, 0.1 is a default value of MaxCapacity), the updated second power parameter value is 0.05w, and the driving interface is called to set the power of the bluetooth chip to be 0.05 w. In the embodiment, the power of the Bluetooth chip is properly and dynamically reduced under the condition that the data volume of the Bluetooth resource pool is stable and the available data volume is sufficient, so that the power consumption of the Bluetooth module can be reduced, and the power consumption of the whole machine is reduced.
Further, the step of triggering the bluetooth sending end to improve the audio quality of bluetooth transmission in step S31 includes:
step S310, triggering the Bluetooth sending end to increase the bit pool parameter value so as to increase the unit frame size.
In this embodiment, a mode of increasing a BitPool parameter Value (BitPool Value) may be adopted to increase the unit frame size, so as to increase the audio quality of bluetooth transmission, and the Value range of the BitPool parameter Value is 2 to 250. When the data volume of the Bluetooth resource pool is sufficient and maintains a relatively stable state, the audio quality of Bluetooth transmission is properly improved, the available data volume of the resource pool is sufficient and has no pause phenomenon, and the audio quality is ensured as far as possible on the premise of ensuring smoothness of the audio in Bluetooth transmission.
Further, step S310 includes:
step S321, sending an instruction for increasing a bit pool parameter value of bluetooth transmission to the bluetooth sending end, so that the bluetooth sending end increases the current bit pool parameter to a first preset bit pool parameter value after receiving the instruction.
In this embodiment, the smart television sends the audio quality instruction for improving bluetooth transmission to the bluetooth sending end, the bluetooth sending end increases the current bit pool parameter value to the first preset bit pool parameter value after receiving the instruction, wherein the first preset bit pool parameter value is 33, the power of the bluetooth chip is properly reduced under the condition of ensuring that the data volume of the bluetooth resource pool is sufficient, the occupied power consumption of the bluetooth module can be reduced, the audio quality is improved simultaneously, and the audio quality is ensured as far as possible on the premise of ensuring that the bluetooth transmission audio is smooth.
