Description

CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims the priority of Chinese Patent Application No. 200910247974.9, entitled “Method for Managing Conflicts between Audio Applications and Conflict Managing Device”, and filed on Dec. 31, 2009, the entire disclosure of which is incorporated herein by reference.

FIELD OF THE INVENTION

The present invention generally relates to a method for managing conflicts between audio applications and a conflict managing device for the audio applications.

BACKGROUND OF THE INVENTION

With development of the multi-media information technology, an integrated application system generally includes several sounder units and several audio applications for meeting needs of users in all aspects. Taking a vehicle-mounted system in an automobile as an example, the vehicle-mounted system generally includes several audio applications such as an FM radio, a GPS audio navigation system and an on-vehicle phone, each of which is corresponding to a respective sounder unit.

Because the audio applications are independent to each other and are corresponding to different sounder units, conflicts may happen between the audio applications. For example, while listening to the FM radio or using the GPS audio navigation system, a driver receives a call through the on-vehicle phone, but the driver can not adjust the ongoing audio applications of the FM radio and the GPS audio navigation system because he or she is driving, so that the call quality will be adversely influenced. Furthermore, the more audio applications are configured in the vehicle-mounted system, the higher possibility of the conflicts between audio applications is. Therefore, several sounder units working together may causes poor audio and visual effects. In prior art, generally, the audio applications are managed separately, but the conflicts between the audio applications corresponding to different sounder units are hardly to be controlled, and the states of the audio applications can not be adjusted automatically according to the conflicts.

In a Chinese Patent application with an application number NO. 2008.10099301.9, a method for managing audio applications is disclosed.

Therefore the invention is not limited within the embodiments described here.

In a conventional integrated system, audio applications are managed separately, several corresponding sounder units may work at the same time and conflicts may happen between the audio applications, which may cause poor audio and visual effects.

A method for managing conflicts between audio applications provided in embodiments of the present invention detects state information of the audio applications. If conflicts happen between the audio applications, a processing strategy will be determined based on an arbitration strategy, and states of the audio applications will be adjusted automatically according to the processing strategy, so as to avoid poor audio and visual effects caused by the conflicts.

FIG. 1 is a flow chart for illustrating a method for managing conflicts between audio applications in an embodiment of the present invention. Referring to FIG. 1, the method includes:

Step S101, acquiring state information of audio applications;

Step S102, determining a processing strategy for the audio applications based on an arbitration strategy when conflicts happen between the audio applications; and

Step S103, adjusting states of the audio applications according to the processing strategy.

In S101, the state information includes state information of the audio applications such as on/off states, and volumes of the audio applications. The step of acquiring the state information of the audio applications includes: Acquiring state information of audio applications in use and newly added audio applications. In an embodiment, the audio applications in use maybe an FM radio being played, and a GPS audio navigation system in use. And the newly added audio applications may be a call received by an on-vehicle phone. In addition, the audio applications being used and the newly added audio applications respectively are corresponding to different sounder units. In the embodiment, a sounder unit of the FM radio is corresponding to a radio trumpet, a sounder unit of the GPS audio navigation system is corresponding to a sounder of the GPS system, and a sounder unit of the on-vehicle phone is corresponding to a receiver of the on-vehicle phone.

In the above embodiment of the present of invention, the corresponding sounder units of the three audio applications (the FM radio, the GPS audio navigation system and the on-vehicle phone) work together at the same time, which may cause conflicts between the audio applications, thereby causing poor audio and visual effects. In S102, the step of determining a processing strategy for the audio applications based on an arbitration strategy includes: Determining a scenario of the audio applications according to the state information based on the arbitration strategy; and determining the processing strategy according to the scenario of the audio applications. In an embodiment, the arbitration strategy is recorded in a strategy file in an XML format, and the XML file may be amended according to practical requirements. For example, the XML file will be amended if a new audio application is added, a new scenario needs to be added or the processing strategy needs to be amended according to the new scenario.

FIG. 2 is a schematic view for showing an arbitration strategy in a first embodiment of the present invention. The arbitration strategy includes state information of audio applications. Specifically, Referring to FIG. 2, there are three audio applications including a first audio application, a second audio application and a third application. In an embodiment, the first audio application is corresponding to an FM radio, the second audio application is corresponding to a GPS audio navigation and the second audio application is corresponding to an on-vehicle phone. Referring to FIG. 2, the arbitration strategy includes state information such as on/off states, that is, an audio application being in a working state or a standby state. In another embodiment, the state information further includes volumes of the audio applications in use. Referring to FIG. 2, the arbitration strategy further includes scenarios corresponding to the audio applications, namely a first scenario, a second scenario, a third scenario and a fourth scenario. Moreover, the arbitration strategy also includes different processing strategies corresponding to each different scenario, and the processing strategies determine volumes of corresponding sounder units or determine the sounder units mute or not. Referring to FIG. 2, ‘Up’ indicates turning up the volume, ‘Down’ indicates turning down the volume, and ‘Muse’ indicates being mute. In an embodiment, the first audio application is corresponding to an FM radio and the second audio application is corresponding to a GPS audio navigation system and both of them are in use, which is corresponding to the third scenario. The third audio application is corresponding to an on-vehicle phone which is a newly added audio application. By combining the state information of the newly added audio application and the first and second audio applications in use, the current state information of the three audio applications is corresponding to the fourth scenario. Thereafter, a processing strategy is determined according to the fourth scenario, which includes adjusting the volumes of the audio applications or making some of them mute. In the embodiment, after the adjustment, the FM radio and the GPS audio navigation system are mute, and the on-vehicle phone works normally.

Referring to FIG. 1, in a second embodiment, in S102, the step of determining a processing strategy for the audio applications based on another arbitration strategy includes: Ranking the audio applications according to priorities of the audio applications based on the arbitration strategy; and determining a processing strategy according to the ranking result of the audio applications. In an embodiment, the arbitration strategy is recorded in a strategy file in an XML format, and the XML file may be amended according to practical requirements. For example, the XML file is amended if a new audio application is added, a new scenario needs to be added or the processing strategy needs to be amended according to the new scenario.

FIG. 3 is a schematic view for illustrating the arbitration strategy in the second embodiment of the present invention. Referring to FIG. 3, the arbitration strategy includes priorities of the audio applications and a processing strategy determined according to the ranking result of the priorities of the audio applications.

In other words, the FM radio has a low priority, the GPS audio navigation system has a middle priority and the on-vehicle phone has a high priority. After obtaining the priorities of the audio applications according to the state information, the audio applications are ranked according to the priorities of the audio applications. In the embodiment, if all of the three audio applications are in a working state, then the result of ranking the audio applications in the order of priorities from high to low is: the third audio application, the second audio application and the first audio application. And then the processing strategy is determined according to the ranking result, including: the FM radio and the GPS audio navigation system being mute, and the on-vehicle phone working normally.

Referring to FIG. 1, S103 is performed, in which the states of the audio applications are adjusted. In an embodiment, the adjustment includes: Configuring the FM radio and the GPS audio navigation system mute; and keeping the on-vehicle phone working normally, which can makes sure the communication process of the on-vehicle phone is not adversely influenced by the other two audio applications.

It should be noted that, after the call received by the on-vehicle phone is over, the on-vehicle phone returns to be in a standby state, the state information of the on-vehicle phone is changed, and the steps S101 to S103 will be performed again. Specifically, the states of the audio applications will be readjusted according to the current state information of the audio applications based on the arbitration strategy. In the embodiment, the FM radio and the GPS audio navigation system are configured to work normally again after the readjusting process.
