In addition, it can be understood that the allocation information determined by the bluetooth device playing information of the playing application and the user operation information includes the allocation situation of the playing application and the bluetooth device, and can reflect the preference of the user to a certain extent, so that the terminal can generate a suitable allocation policy according to the allocation information to allocate the playing application to the bluetooth device for playing.
For example, taking a smart phone terminal as an application scene, in the embodiment of the invention, a mobile phone Bluetooth is opened, information of an available Bluetooth device group is obtained by searching or connecting, the available Bluetooth device group comprises a plurality of available Bluetooth devices, then Bluetooth device playing information and user operation information of a playing application in the mobile phone are detected, and the Bluetooth device playing information of the playing application can comprise an allocation playing record between the playing application and the Bluetooth device; the user operation information may include information received by the terminal to cancel playing of the audio of the playing application by the bluetooth device, or may include information received by the terminal to schedule the playing application to play by other bluetooth devices, and then, according to the bluetooth device playing information and the user operation information, an allocation mapping relationship between the playing application and the bluetooth device may be obtained, as allocation information, and then, according to the allocation information, the playing application is allocated to a corresponding bluetooth device, so that the bluetooth device plays the playing application according to the allocation information, thereby realizing that one terminal is used to control multiple bluetooth devices to play different audio.
In addition, as shown in fig. 3, fig. 3 is a flowchart of determining allocation information when a playback application prepares to play a playback audio in the bluetooth playback method according to an embodiment of the present invention. Regarding the determination of the allocation information of the playback application to the bluetooth device according to the bluetooth device playback information and the user operation information in step S300 described above, there are included, but not limited to, step S610, step S620, and step S630.
Step S610, when detecting that the playing application is ready to play audio, acquiring Bluetooth equipment playing information of the ready-to-play application;
step S620, determining the priority of the Bluetooth device in the available Bluetooth device group according to the Bluetooth device playing information and the user operation information of the application to be played;
in step S630, allocation information is determined according to the priority of the bluetooth device and the user operation information.
Specifically, when the playing application prepares to play audio, the embodiment of the invention can acquire the Bluetooth equipment playing information of the playing application, determine the priority of the Bluetooth equipment in the available Bluetooth equipment group according to the Bluetooth equipment playing information of the playing application and the user operation information, and determine the allocation information according to the priority of the Bluetooth equipment and the user operation information.
In this embodiment, when the terminal detects that a certain application is about to play audio, before audio is not played, the terminal obtains the bluetooth device that plays the audio of the application ready for playing for the last time, which is equivalent to obtaining the playing information of the bluetooth device that plays the audio of the application ready for playing, then detects the record that is cancelled for playing of the bluetooth device that plays the audio of the application ready for the last time, obtains the priority from the playing information of the bluetooth device that plays the application ready for playing and the record that is cancelled for playing, and before the allocation of the application and the bluetooth device is performed according to the priority, pops up a prompt message at the terminal to prompt the user whether to accept the allocation, if not accept the allocation, cancel the allocation at this time, or in a period of popping up the prompt message, if the user does not have any operation feedback, the default user accepts the allocation at this time, and finally determines the lower allocation information.
In the above embodiment, the priority of the bluetooth device in the available bluetooth device group is determined according to the bluetooth device play information and the user operation information of the ready-to-play application, and then the allocation information more accords with the user preference and more reflects the real-time preference of the user can be obtained according to the processing procedure of determining the allocation information according to the priority of the bluetooth device and the user operation information.
It should be noted that, the priority of the bluetooth device in the available bluetooth device group may be unilateral priority or may be multiple priority; the user operation information may include information received by the terminal to cancel audio of the playing application played by the bluetooth device, or may include information received by the terminal to schedule the playing application to play by other bluetooth devices.
For example, in the embodiment of the present invention, the unilateral priority may sort the bluetooth devices of the available bluetooth device group according to the bluetooth device play information and the user operation information, where the closer the sorting position is to the first order, the higher the priority, and when the priority is in the first order, the highest priority; the multiple priorities may be obtained according to multiple indexes, for example, 2 priorities may be obtained according to the index of the number of times the bluetooth device is allocated to play and the index of the number of times the bluetooth device is cancelled, and then the allocation information may be determined according to the importance of the 2 priorities, where the importance may be reflected by the weight, so that the allocation information more conforming to the preference of the user may be obtained.
In addition, as shown in fig. 4, fig. 4 is a flowchart of determining priority according to a historical bluetooth play record in a bluetooth play method according to an embodiment of the present invention. Regarding the determination of the priority of bluetooth devices in the available bluetooth device group according to the bluetooth device play information and the user operation information of the ready-to-play application in step S620 described above, there is included, but not limited to, step S700.
In step S700, when it is detected that the play information of the bluetooth device ready for playing the application has a play record, and the historical bluetooth device recorded by the play record exists in the available bluetooth device group, the priority of the historical bluetooth device in the available bluetooth device group is adjusted according to the cancelling bluetooth play record of the ready for playing the application in the user operation information.
Specifically, when the playing application prepares to play audio, the embodiment of the invention can acquire the playing information of the Bluetooth device to be played, when the playing information of the Bluetooth device to be played is detected to have a playing record, and the historical Bluetooth device recorded by the playing record exists in the available Bluetooth device group, and then the priority of the historical Bluetooth device in the available Bluetooth device group is adjusted according to the cancelling Bluetooth playing record of the prepared playing application in the user operation information, so that the priority of the Bluetooth device more conforming to the user preference can be obtained.
In addition, it is understood that the ready-to-play application refers to a play application that prepares to play audio, and that the play record of the bluetooth device play information of the ready-to-play application includes historical bluetooth device information that was once played by the ready-to-play application.
In addition, it is understood that the historical bluetooth device may be one bluetooth device that has been recently assigned, or may be a plurality of bluetooth devices that have been assigned.
In the embodiment of the present invention, when the playing application prepares to play audio, the embodiment of the present invention can obtain the playing information of the bluetooth device preparing to play application, when it is detected that the playing information of the bluetooth device preparing to play application has a playing record, and the historical bluetooth device recorded by the playing record exists in the available bluetooth device group, if the cancelling bluetooth playing record of the preparing to play application does not include the historical bluetooth device in the user operation information, that is, the historical bluetooth device is not cancelled, at this time, the priority of the historical bluetooth device which has not cancelled to play can be adjusted, and the processing procedure can obtain the priority of the bluetooth device which better accords with the user preference, so as to formulate a suitable allocation policy.
In addition, it should be noted that, in the case of unilateral priority, the adjustment may be to adjust the priority of the historical bluetooth device to the highest, or just increase the priority by one level; in the case of multiple priorities, only one aspect of priority may be increased, or multiple aspects of priority may be increased at the same time, where the manner of increasing may be to increase the priority to the highest level, or only increase the priority by one level, where the manner of adjusting is not described in detail herein, so long as the preference of the user can be reflected.
For example, in the embodiment of the present invention, 2 priorities may be obtained according to the number of times index of being allocated to play of the bluetooth device and the device play duration index, when the play application prepares to play audio, the embodiment of the present invention may obtain bluetooth device play information of the prepare to play application, when it detects that there is a play record in the bluetooth device play information of the prepare to play application, and the historical bluetooth device recorded in the play record exists in the available bluetooth device group, if the cancelling bluetooth play record of the prepare to play application in the user operation information does not include the historical bluetooth device, i.e. the historical bluetooth device is not cancelled, at this time, the priority of the historical bluetooth device that has not cancelled to play may be adjusted, where the adjustment may be to increase the priority related to the number of times index of being allocated to play of the bluetooth device, or to increase the priority related to the device play index, and the adjustment may be to the highest, or only to increase the priority, where the adjustment is not described herein, so long as the priority may be reflected in one level of preference of the user.
In addition, as shown in fig. 5, fig. 5 is a flowchart of determining priority when a user does not cancel playback in the bluetooth playback method according to an embodiment of the present invention. Regarding the above-mentioned step S700, the priority of the bluetooth device in the available bluetooth device group is adjusted according to the cancellation bluetooth play record of the ready-to-play application in the user operation information, which includes, but is not limited to, step S800.
Step S800, according to the cancelling Bluetooth playing record of the preparing playing application in the user operation information, the priority of the history Bluetooth equipment which does not cancel playing in the available Bluetooth equipment group is adjusted to the highest priority, so that the history Bluetooth equipment which does not cancel playing is preferentially distributed.
Specifically, when the playing application prepares to play audio, the embodiment of the invention can acquire the playing information of the Bluetooth device ready to play the application, when the existence of the playing record in the playing information of the Bluetooth device ready to play the application is detected, and the historical Bluetooth device recorded by the playing record exists in the available Bluetooth device group, if the cancelling Bluetooth playing record of the ready to play application does not include the historical Bluetooth device in the user operation information, that is, the historical Bluetooth device is not cancelled, at the moment, the priority of the historical Bluetooth device which is not cancelled can be adjusted to the highest priority, so that the historical Bluetooth device which is not cancelled is preferentially allocated, and the priority of the Bluetooth device which is more in line with the user preference can be obtained.
In addition, it should be noted that, in the case of unilateral priority, the priority of the historical bluetooth device may be adjusted to be the highest; in the case of multiple priority levels, only one of the priority levels may be adjusted to the highest level, so that the historical bluetooth device that has not taken the play out may be preferentially allocated to the play application, or the multiple priority levels may be simultaneously adjusted to the highest level, and the manner of adjusting the priority level to the highest level is not described in detail herein, so long as the preference of the user can be reflected, and the historical bluetooth device that has not taken the play out may be preferentially allocated to the play application.
In addition, as shown in fig. 6, fig. 6 is a flowchart of determining priority according to bluetooth device play information in the bluetooth play method according to an embodiment of the present invention. Regarding the determination of the priority of bluetooth devices in the available bluetooth device group according to the bluetooth device play information and the user operation information of the ready-to-play application in step S620 described above, including but not limited to step S900.
In step S900, when it is detected that the bluetooth device playing information of the application to be played is null, or the historical bluetooth device recorded by the bluetooth device playing information does not exist in the available bluetooth device group, or the cancel playing record of the historical bluetooth device exists in the user operation information, the priority of the bluetooth device is updated.
Specifically, when the playing application prepares to play audio, the terminal of the embodiment of the invention can acquire the bluetooth device playing information of the ready-to-play application, and when detecting that the playing record of the bluetooth device playing information of the ready-to-play application is empty, i.e. no history playing information exists, or the history bluetooth device recorded by the playing record does not exist in the available bluetooth device group, or the user operation information has a bluetooth cancellation playing record of the history bluetooth device, i.e. the user cancels playing the history bluetooth device recorded by the playing record, and under the condition that the conditions are all met, the priority of the bluetooth device in the available bluetooth device group is updated, so that the playing resources of the bluetooth device in the available bluetooth device group are reasonably distributed.
In addition, it should be noted that, the priority of the bluetooth device in the available bluetooth device group is updated, and the priority of a certain idle bluetooth device can be changed, so that the idle bluetooth device can play the audio from the application to be played, and the playing resources of the bluetooth device in the available bluetooth device group are reasonably utilized. It is understood that an idle bluetooth device may refer to a bluetooth device that has been assigned to other applications but has not played audio.
In addition, regarding the determination of allocation information according to the priority of bluetooth devices and user operation information in step S630 described above, there are included, but not limited to, step S1010 and step S1020.
Step S1010, pre-allocation information is determined according to the priority of the Bluetooth equipment;
step S1020, determining allocation information according to the pre-allocation information and the user operation information.
Specifically, when the playing application prepares to play audio, the embodiment of the invention can acquire the playing information of the Bluetooth device to be played, determine the priority of the Bluetooth device in the available blue tooth device group according to the playing information of the Bluetooth device to be played and the user operation information, determine pre-allocation information according to the priority of the Bluetooth device, and finally determine lower allocation information according to the pre-allocation information and the user operation information.
In addition, it should be noted that the pre-allocation information corresponds to a preliminary allocation scheme, and according to the pre-allocation information and the user operation information, a final allocation information more suitable for the real-time preference of the user can be obtained.
In this embodiment, when the terminal detects that a certain application is about to play audio, before audio is not played, the terminal obtains the bluetooth device that plays the audio of the application ready for playing for the last time, which is equivalent to obtaining the playing information of the bluetooth device that plays the audio of the application ready for playing, then detects the record that is cancelled for playing the bluetooth device that plays the audio of the application ready for playing the last time, obtains the priority from the playing information of the bluetooth device that plays the application ready for playing and the record that is cancelled for playing, determines a preliminary allocation policy according to the obtained priority, that is, obtains pre-allocation information, and obtains final allocation information according to the pre-allocation information, for example, before the allocation of the application and the bluetooth device is performed according to the priority, a prompt message may be popped up at the terminal to prompt the user whether to accept the allocation, if not accept the allocation is cancelled, or if the user does not have any operation feedback, the user is defaulted to accept the allocation, and finally determines the allocation information, and such a processing procedure can determine allocation information that is more in accordance with the preference of the user in real time.
In addition, as shown in fig. 7, fig. 7 is a flowchart of audio allocation according to priority in the bluetooth playing method according to an embodiment of the present invention. The above-mentioned step S400 is related to allocating the play application to the bluetooth device according to the allocation information, so that the bluetooth device plays the play application according to the allocation information, including but not limited to step S1100.
Step S1100, according to the allocation information, the Bluetooth device with high priority is allocated to the playing application running first, so that the Bluetooth device plays the playing application running first according to the allocation information.
Specifically, firstly, information of available Bluetooth equipment groups is obtained, wherein the available Bluetooth equipment groups are a set of a plurality of available blue tooth equipment; then, detecting the Bluetooth equipment playing information and user operation information of the playing application; then, determining the priority of the Bluetooth device in the available Bluetooth device group according to the Bluetooth device playing information and the user operation information to determine the allocation information, or when the situation that the playing application is ready to play audio is detected, acquiring the Bluetooth device playing information of the ready-to-play application, and determining the priority of the Bluetooth device in the available Bluetooth device group according to the Bluetooth device playing information of the ready-to-play application and the user operation information; and finally, according to the allocation information, the Bluetooth equipment with high priority is allocated to the playing application running first, so that the Bluetooth equipment plays the playing application according to the allocation information.
In addition, it should be noted that the priority of the bluetooth device in the available bluetooth device group may be unilateral priority or may be multiple priority; the user operation information may include information received by the terminal to cancel audio of the playing application played by the bluetooth device, or may include information received by the terminal to schedule the playing application to play by other bluetooth devices.
For example, in the embodiment of the present invention, the unilateral priority may sort the bluetooth devices of the available bluetooth device group according to the bluetooth device play information and the user operation information, where the closer the sorting position is to the first order, the higher the priority is; the multiple priorities may be obtained according to multiple indexes, for example, 2 priorities are obtained according to the index of the number of times the bluetooth device is allocated to play and the index of the number of times the bluetooth device is cancelled, and the final priority is determined according to the importance of the 2 priorities. After the priority is determined, the bluetooth devices are sequentially allocated to the playing application according to the order of the priority from high to low, for example, the bluetooth device with the highest priority is firstly allocated to the playing application which is opened first, then the bluetooth device with the second highest priority can be allocated to the second playing application which is opened, and the following bluetooth devices are also allocated according to the rule.
In addition, as shown in fig. 8, fig. 8 is a flowchart of processing allocation information when there is a new bluetooth device in the bluetooth playing method according to one embodiment of the present invention. Regarding the determination of the allocation information of the playback application to the bluetooth device based on the bluetooth device playback information and the user operation information in step S300 described above, there are included, but not limited to, step S1210, step S1220, and step S1230.
