Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for playing a car audio according to an embodiment of the present invention. The embodiment can be applied to any situation of playing the corresponding audio through the audio application in the multi-vehicle operating system. The method for playing the car audio provided by the embodiment of the present invention may be executed by the device for playing the car audio provided by the embodiment of the present invention, and the device may be implemented in a software and/or hardware manner, and is integrated into a vehicle for executing the method, and the vehicle is configured with a plurality of car operating systems.
Specifically, referring to fig. 1, the method specifically includes the following steps:
s110, if an audio focus application request of a target audio application in any vehicle-mounted operating system is received through an audio agent service in the main vehicle-mounted operating system, determining the associated audio application to which the audio focus belongs currently.
Specifically, in order to ensure independent control of entertainment facilities in different cabin positions in a vehicle, a set of independent vehicle-mounted operating system is respectively operated in different cabin positions such as central control, copilot and back row entertainment in the vehicle cabin, so that a plurality of sets of vehicle-mounted operating systems are configured in the vehicle cabin, and each vehicle-mounted operating system is configured with corresponding audio application, so that entertainment diversity in the vehicle running process is increased; however, since only one set of sound system is usually configured on the vehicle, when the audio of a certain audio application on multiple vehicle-mounted operating systems is played simultaneously, the problem of noisy audio playing between the multiple vehicle-mounted operating systems is caused, so a set of audio focus mechanism that can comply with the same commonly needs to be set between the multiple vehicle-mounted operating systems of the vehicle, that is, in any audio application in the multiple vehicle-mounted operating systems, only the audio application that successfully preempts the audio focus is allowed to play the corresponding audio.
It should be noted that, the vehicle-mounted operating system in this embodiment may be any operating system among a Windows operating system, a macOS operating system, a Linux operating system, an iOS operating system, and an Android operating system, which is not limited to this; meanwhile, the audio applications configured on the vehicle-mounted operating system may include any applications having a voice playing function, such as a call application, an audio player, a traffic report application, and the like.
In this embodiment, first, any one of the onboard operating systems is selected from the plurality of onboard operating systems configured on the vehicle to serve as a proxy service host for analyzing the preemption of the audio focus by the audio application on each onboard operating system, that is, the main onboard operating system in this embodiment, at this time, a corresponding audio proxy service is configured in the main onboard operating system, and the audio proxy service supports execution of the audio focus preemption operation of the audio application on any one of the onboard operating systems.
In addition, in order to ensure the accuracy of communication interaction between the main onboard operating system and other onboard operating systems, a corresponding Audio Manager (Audio Manager) is configured on each onboard operating system, and a corresponding Audio focus interface (Audio focus API) is developed in an Audio agent service of the main onboard operating system, so that each onboard operating system calls the Audio focus interface developed in the Audio agent service on the main onboard operating system through the Audio Manager, thereby realizing the communication interaction between the main onboard operating system and other onboard operating systems.
Optionally, in order to ensure the timeliness of the application of the audio focus by each audio application in the multiple onboard operating systems, in this embodiment, the audio agent service configured in the main onboard operating system is required to be in a real-time working state, at this time, if a certain audio application in any onboard operating system currently needs to play a corresponding audio, the audio application may serve as a target audio application in this embodiment, an audio manager on the onboard operating system is used to call an audio focus interface developed on the audio agent service in the main onboard operating system, so as to report a corresponding audio focus application request to the audio agent service in the main onboard operating system, and further, the audio agent service in the main onboard operating system may receive the audio focus application request reported by the target audio application, and after receiving the audio focus application request through the audio agent service in the main onboard operating system, in order to ensure the preemption accuracy of the audio focus, firstly, a related audio application to which the audio focus belongs currently is found, and the related audio application can be an audio application which is currently playing audio on any vehicle-mounted operating system, so that whether the target audio application can preempt the audio focus from the related audio application or not is accurately judged in the following.
In this embodiment, in order to ensure real-time operation of the audio agent service in the main onboard operating system, a set of corresponding audio agent service instances is generated by simulation according to the function of the audio agent service, and the corresponding audio agent service instances are run through the main onboard operating system, so that an audio focus processing message of any audio application in each onboard operating system is received in real time, where the audio focus processing message may be various audio focus related information such as an audio application request for an audio focus, a release notification, and a change state.
And S120, determining an audio focus preemption result of the target audio application and the associated audio application according to the playing priority of the target audio application and the associated audio application.
Optionally, after receiving an audio focus application request of a target audio application and determining a related audio application to which an audio focus belongs at present, it is required to determine whether the target audio application can rob away the audio focus from the related audio application, at this time, since audio categories played by different audio applications are also different, and for audio played simultaneously in different audio categories, a user usually preferentially selects audio with high real-time performance for playing, for example, when receiving a call request while playing music, the user may select to pause playing music to answer the call, or when receiving a road condition broadcast voice while playing music in a vehicle driving process, the user may reduce the playing volume of the music to broadcast the road condition information as much as possible by voice; therefore, by analyzing the audio playing categories of different audio applications, corresponding playing priorities can be set for the audio applications on each vehicle-mounted operating system, for example, the playing priority of the call application is greater than that of the audio player and the road condition broadcast application, and the playing priority of the road condition broadcast application is greater than that of the audio player.
At this time, after determining the associated audio application to which the audio focus belongs currently, the playing priorities of the target audio application and the associated audio application are respectively found out, and then whether the target audio application can preempt the audio focus from the associated audio application is judged by comparing the playing priorities between the target audio application and the associated audio application, and the audio application with the higher playing priority can play the audio focus of the audio application with the lower preempting priority, so that the audio focus preempting results of the target audio application and the associated audio application are respectively determined, that is, the audio focus is preempted by the audio application with the highest playing priority at last.
It should be noted that, because the audio applications in the multiple onboard operating systems may report the corresponding audio focus application requests to the audio agent service in the main onboard operating system at the same time, the target audio application in this embodiment may be one or multiple, when multiple target audio applications are provided, the playing priority of each target audio application and the associated audio application is still compared, and then the audio application with the highest playing priority in each target audio application and the associated audio application preempts the audio focus, so that the audio application with the highest playing priority plays the corresponding audio, and the audio application without preempting the audio focus does not play the audio, thereby avoiding the noisy audio play between the multiple onboard operating systems.
The technical scheme provided by the embodiment runs the corresponding audio proxy service on the main vehicular operating system in the multi-vehicular operating system, when an audio focus application request of a target audio application in any vehicle-mounted operating system is received through an audio agent service in the main vehicle-mounted operating system, an associated audio application to which an audio focus belongs is determined at first, then re-determining the audio focus preemption result of the target audio application and the associated audio application according to the playing priority of the target audio application and the associated audio application, therefore, a commonly observed audio focus mechanism is realized on the multiple vehicle-mounted operating systems, so that the audio application in each vehicle-mounted operating system can play the corresponding audio according to a certain rule, the noisy performance of audio playing among the multiple vehicle-mounted operating systems is avoided, and the coordination of audio playing among the multiple vehicle-mounted operating systems is improved.
Example two
Fig. 2 is a flowchart of a method for playing a car audio according to a second embodiment of the present invention. The embodiment of the invention is optimized on the basis of the embodiment. Optionally, in this embodiment, a detailed explanation is mainly given to a specific playing process of the played audio by an audio application that has preempted an audio focus and an audio application that does not preempt an audio focus, in the target audio application and the associated audio application.
Specifically, referring to fig. 2, the method of this embodiment may specifically include:
s210, if an audio focus application request of a target audio application in any vehicle-mounted operating system is received through an audio agent service in the main vehicle-mounted operating system, determining the associated audio application to which the audio focus belongs currently.
And S220, determining the audio focus preemption result of the target audio application and the associated audio application according to the playing priority of the target audio application and the associated audio application.
And S230, feeding back corresponding audio focus preemption results to the target audio application and the associated audio application respectively, so that the target audio application and the associated audio application execute corresponding audio playing operation according to the corresponding audio focus preemption results respectively.
Optionally, after determining the audio focus preemption results of the target audio application and the associated audio application, in order to ensure that the audio in the audio application is accurately played, in this embodiment, corresponding audio focus preemption results are also fed back to the target audio application and the associated audio application, and when the target audio application preempts an audio focus from the associated audio application, that is, the associated audio application does not preempt the audio focus, the target audio application is caused to play the corresponding audio, and when the associated audio application loses the audio focus, the audio playing is exited or paused or the volume of the audio playing is reduced, so that the user focuses on the audio played by the target audio application; and when the target audio application does not preempt the audio focus from the associated audio application, that is, the associated audio application still preempts the audio focus, the target audio application will not play the audio, and the associated audio application continues to play the corresponding audio.
Further, in order to ensure the audio playing performance of the associated audio application, in this embodiment, if the associated audio application is not empty and the associated audio application does not preempt the audio focus, an audio playing coordination parameter of the associated audio application under the condition that the audio focus is not preempted is set according to the audio playing type of the target audio application which has preempted the audio focus; and feeding back the audio playing coordination parameters under the condition that the audio focus is not preempted to the associated audio application so that the associated audio application executes corresponding audio playing operation according to the audio playing coordination parameters under the condition that the audio focus is not preempted.
Specifically, if the associated audio application is not empty and the associated audio application does not occupy the audio focus, it indicates that the associated audio application is not focused by the user at present, and when the target audio application which occupies the audio focus plays the corresponding audio, because the audio playing types are different, the playing requirements for the associated audio application which does not occupy the audio focus are also different, for example, if the call application occupies the audio focus from the music player, the music player is required to pause playing the audio in order to ensure the call quality, and if the road condition broadcast application occupies the audio focus from the music player, the music player is only required to reduce the volume of audio playing, so that the road condition does not affect the definition of the broadcast voice; therefore, in this embodiment, after determining that the associated audio application is not empty and the associated audio application does not preempt the audio focus, the audio play coordination parameter of the associated audio application under the condition that the audio focus is not preempted is set by analyzing the audio play type of the target audio application that has preempted the audio focus this time, and the audio play coordination parameter can indicate that the associated audio application needs to quit audio play or pause audio play when the audio focus is not preempted, or only needs to reduce the volume of audio play; then, when the corresponding audio focus preemption result is fed back to the associated audio application, the audio play coordination parameter of the associated audio application under the audio focus not preempted is also fed back synchronously, so that the associated audio application directly executes the corresponding audio play operation according to the audio play coordination parameter under the audio focus not preempted, and the audio play is not required to be quitted each time the audio focus is not preempted, thereby ensuring the play performance of the associated audio application.
S240, if the associated audio application is not empty and an audio focus release notice of the target audio application which preempts the audio focus is received through the audio agent service in the main onboard operating system, the current audio focus is continuously distributed to the associated audio application.
Optionally, if the associated audio application is not null and the associated audio application does not preempt the audio focus, which means that the target audio application preempts the audio focus, the target audio application may play the corresponding audio, and at this time, after the audio playing is completed, for example, a call is completed or a road condition broadcast is completed, the audio manager on the onboard operating system may invoke the audio focus interface on the drink agent service in the onboard operating system to report a corresponding audio focus release notification to the audio agent service in the onboard operating system, and at this time, if the audio focus release notification of the target audio application that has preempted the audio focus is received through the audio agent service in the onboard operating system, in order to ensure the continuity of the audio playing, when the associated audio application does not quit the last audio playing, the current audio focus is directly allocated to the associated audio application continuously, so that the last audio playback is resumed by the associated audio application.
And S250, feeding back successful preemption information of the audio focus to the associated audio application so that the associated audio application continues to execute corresponding audio playing operation according to the audio playing default parameters.
Optionally, after the current audio focus is continuously allocated to the associated audio application, the successful preemption information of the audio focus is fed back to the associated audio application, so that the associated audio application can continue to execute the corresponding audio playing operation according to the audio playing default parameter, and the audio playing default parameter can indicate the audio playing standard of the associated audio application when the audio focus is preempted, for example, the playing volume of the audio player is reduced during the road condition broadcast, and the audio player continues to play music with the original volume after the road condition broadcast is finished.
The technical scheme provided by the embodiment runs the corresponding audio proxy service on the main vehicular operating system in the multi-vehicular operating system, when an audio focus application request of a target audio application in any vehicle-mounted operating system is received through an audio agent service in the main vehicle-mounted operating system, an associated audio application to which an audio focus belongs is determined at first, then re-determining the audio focus preemption result of the target audio application and the associated audio application according to the playing priority of the target audio application and the associated audio application, therefore, a commonly observed audio focus mechanism is realized on the multiple vehicle-mounted operating systems, so that the audio application in each vehicle-mounted operating system can play the corresponding audio according to a certain rule, the noisy performance of audio playing among the multiple vehicle-mounted operating systems is avoided, and the coordination of audio playing among the multiple vehicle-mounted operating systems is improved.
