And after the kernel is started, loading the Shell and the user application program. The application program is compiled into machine code after being started, and a process is formed.

Referring to fig. 4, in some embodiments, the system is divided into four layers, which are an Application (Applications) layer (abbreviated as "Application layer"), an Application Framework (Application Framework) layer (abbreviated as "Framework layer"), an Android runtime (Android runtime) and system library layer (abbreviated as "system runtime library layer"), and a kernel layer from top to bottom.

In some embodiments, at least one application program runs in the application program layer, and the application programs can be Window (Window) programs carried by an operating system, system setting programs, clock programs, camera applications and the like; or may be an application developed by a third party developer such as a hi program, a karaoke program, a magic mirror program, or the like. In specific implementation, the application packages in the application layer are not limited to the above examples, and may actually include other application packages, which is not limited in this embodiment of the present application.

The framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

As shown in fig. 4, in the embodiment of the present application, the application framework layer includes a manager (Managers), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used for interacting with all activities running in the system; the Location Manager (Location Manager) is used for providing the system service or application with the access of the system Location service; a Package Manager (Package Manager) for retrieving various information related to an application Package currently installed on the device; a Notification Manager (Notification Manager) for controlling display and clearing of Notification messages; a Window Manager (Window Manager) is used to manage the icons, windows, toolbars, wallpapers, and desktop components on a user interface.

In some embodiments, the activity manager is to: managing the life cycle of each application program and the general navigation backspacing function, such as controlling the exit of the application program (including switching the user interface currently displayed in the display window to the system desktop), opening, backing (including switching the user interface currently displayed in the display window to the previous user interface of the user interface currently displayed), and the like.

In some embodiments, the window manager is configured to manage all window processes, such as obtaining a display size, determining whether a status bar is available, locking a screen, intercepting a screen, controlling a display change (e.g., zooming out, dithering, distorting, etc.) and the like.

In some embodiments, the system runtime layer provides support for the upper layer, i.e., the framework layer, and when the framework layer is used, the android operating system runs the C/C + + library included in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software.

For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various applications for multimedia content playback. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

In some embodiments, an application center may provide storage for various applications. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on the smart television. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

The resources played by the display apparatus 200 include a video resource and an audio resource, and in general, the video resource and the audio resource are played in synchronization so that a user hears sound of things in a video and the like while viewing the video resource.

The resource may also be represented as programs of the display device, each Program has its corresponding PSI (Program Specific Information), and the PSI includes a PMT (Program Map Table), audio Information and video Information describing the Program, and the like. The PMT also contains the bystander information which conveys a visual picture by simple and vivid language and can help the blind or the visually impaired person to test the visual image of the video resource presentation picture.

However, when a user with impaired vision and a user with normal vision simultaneously view the display device resources, both the impaired and the normal users hear the bystander information. For a user with normal vision, the bystander information is not usually needed to assist in perceiving a visual picture, and the output of the bystander information can influence the user with normal vision to perceive background music (such as bird song and rain) in an audio resource and the like, and influence the user with normal vision to truly perceive a video resource picture.

Based on the above problems, embodiments of the present application provide a display device resource playing method and a display device, which can select a corresponding audio output device to play an audio resource and voice-over information according to an earphone mode, an audio mode, and a voice-over output mode in a view-impaired mode when the display device 200 is connected to an earphone. The resource playing requirements of the vision disorder user and the vision normal user can be met simultaneously, when the vision disorder user and the vision normal user watch the resources simultaneously, the voice frequency content of the vision normal user can not be affected by the voice information provided for the vision disorder user, and the resource watching experience of different users can be guaranteed simultaneously.

The display device 200 provided by the embodiment of the present application may include at least a display 275 and a controller 250. The display 275 may show a video resource in the resources played by the display device 200, and the controller 250 may obtain some current peripheral connection states and mode setting conditions of the display device 200, and control the display 275 to perform corresponding mode display and control audio resources and output of voice-over information.

In the embodiment of the present application, the peripheral connection state of the display device 200, that is, the connection state of the earphone, and the controller 250 needs to determine whether the display device 200 is connected to the earphone device in addition to the speaker of the display device itself. Whether to connect the earphone or not requires the user to select according to the requirements of the user. After the earphone is connected, the playing mode of the audio resource comprises an earphone, an earphone and a loudspeaker, wherein the earphone is used for playing the audio resource and the earphone and the loudspeaker are used for simultaneously playing the audio resource; without connecting to the headphones, the audio resource can only be played by the speakers of the display device 200.

Fig. 6 is a schematic diagram of a setting interface according to an embodiment of the present disclosure. After the user selects to connect the headphones to the display device 200, the controller 250 detects that the display device 200 is connected to the headphones, and at this time, the headphone mode on the setting interface as shown in fig. 6 needs to be set to a highlighted selectable state, so that the user can select the playing mode of the audio resource. The earphone mode specifically comprises an earphone, an earphone and a loudspeaker, wherein when the earphone mode is the earphone, the user selects the earphone to play audio resources; when the headphone mode is headphone and speaker means that the user chooses to play the audio asset simultaneously by headphone and speaker.

After the user selects a particular headphone mode, the controller 250 detects the current headphone mode and determines in what manner to play the audio resource.

When the visually impaired user and the sighted user jointly view the display device 200, the earphone and speaker modes are typically selected so that different users listen to the audio resource through different devices without interfering with each other.

Also, when the vision-impaired user and the vision-normal user jointly view the display device 200, it is necessary to select the audio mode of the display device 200 as the vision-impaired mode in order for the vision-impaired user to hear the bystander information in the resource.

Fig. 7 is a schematic diagram of an audio mode interface according to an embodiment of the present application. As shown in fig. 7, the controller 250 needs to adjust the audio mode on the audio mode interface to the visually impaired mode after detecting the audio mode. And, only when the earphone mode is earphone and speaker, as in the audio mode shown in fig. 7, the voice-over output mode will be changed to the highlighted selectable mode, and at this time, the user can select a specific voice-over output mode. When the earphone mode is the earphone mode or the display device 200 is not connected with the earphone, the voice-over output mode on the audio mode interface is in a gray-set non-selectable state, as shown in fig. 8, that is, only voice-over information can be output by the earphone or only voice-over information can be output by the speaker of the display device 200.

As shown in fig. 6 and 7, the display device 200 can currently play audio through both earphones and speakers, but in order to facilitate the users with impaired vision and the users with normal vision to listen to together without affecting each other, the users also select which device to play the voice-over information, i.e., select the voice-over output mode. The voice-over output modes include three, headphones, speakers, and all.

If the vision-impaired user listens using the headphones, the voice-over output mode may be selected as the headphones, so that the vision-impaired user can listen to the audio resource and voice-over information through the headphones at the same time, and the vision-impaired user can listen to only the audio resource through the speakers of the display device 200. In this case, after detecting the selection of the user, the controller 250 needs to adjust the voice-over output mode on the audio mode interface to be the earphone, as shown in fig. 7, at this time, the earphone plays the audio resource and the voice-over information at the same time, and the speaker plays the audio resource.

If the visually impaired user listens using the speakers, the voice-over output mode may be selected as the speakers, so that the visually impaired user may listen to the audio resource and voice-over information simultaneously through the speakers of the display device 200, and the sighted user may listen to only the audio resource through the headphones. In this case, after detecting the selection of the user, the controller 250 needs to adjust the voice-over output mode on the audio mode interface to the speaker, as shown in fig. 9, at this time, the speaker plays the audio resource and the voice-over information at the same time, and the earphone plays the audio resource.

If the user selects the voice-over output mode to be full, the audio resource and voice-over information can be heard by the vision-impaired user and the vision-normal user by selecting the earphone or the loudspeaker. In this case, the controller 250 may need to adjust the voice-over output mode on the audio mode interface to all after detecting the user's selection, as shown in fig. 10, and at this time, the headphones and the speaker play the audio resource and the voice-over information at the same time.

According to the scheme, the resource playing requirements of the vision disorder user and the vision normal user can be met simultaneously, when the vision disorder user and the vision normal user watch the resources simultaneously, the vision disorder user can independently use the earphone to listen to the audio resources and the voice-over information, and the vision normal user can listen to the audio resources by using the loudspeaker of the display device 200; or the visually impaired user may listen to the audio resource and the bystander information using the speaker of the display device 200, and the visually impaired user may listen to the audio resource using the headphones alone. Therefore, the voice-side information provided for the vision-impaired user does not influence the audio content of the vision-normal user, and the resource appreciation experience of different users can be ensured at the same time.

In some embodiments, if the controller 250 detects that the display device 200 is connected to headphones, the headphone mode is headphone and speaker, and the audio mode is normal, which indicates that the user viewing the display device 200 does not need to listen to the voice-over information, the controller 250 needs to adjust the audio mode on the audio mode interface to normal, as shown in fig. 11, and the controller 250 selects headphones and speakers to play the audio asset at the same time without playing the voice-over information.

In some embodiments, if controller 250 detects that display device 200 is connected to a headset and the headset mode is headset, then the user is said to have only selected to play the audio asset using the headset and the speakers of display device 200 are silent. At this time, the controller 250 needs to adjust the earphone mode on the setting interface as shown in fig. 6 to the earphone, and the adjusted setting interface is as shown in fig. 12. In this case, the voice-over output mode on the audio mode interface is changed to the gray-out state, and only the earphone plays the voice data no matter the controller 250 continuously detects that the audio mode is the normal mode or the visual-impaired mode. When the audio mode is the normal mode, the controller 250 selects the earphone to play only the audio resource; when the audio mode is the visually impaired mode, the controller 250 selects the headphones to simultaneously play the audio resources and the voice-over information.

In some embodiments, if controller 250 detects that display device 200 is not connected to headphones, the user is instructed to only select to play the audio asset using the speakers of display device 200. At this time, the control 250 needs to gray out the headphone mode on the setting interface as shown in fig. 6 and adjust to the unavailable state to indicate no headphone connection. In this case, the voice-over output mode on the audio mode interface may also be changed to a grayed-out non-selectable state, and only the speaker plays the voice-over output mode no matter whether the controller 250 continuously detects that the audio mode is the normal mode or the visual-impairment mode. When the audio mode is the normal mode, the controller 250 selects the speaker of the display apparatus 200 to play only the audio resource; when the audio mode is the visually impaired mode, the controller 250 selects the speaker of the display apparatus 200 to simultaneously play the audio resource and the voice-over information.

Referring to fig. 13, the scheme in the foregoing embodiment of the present application may refer to that, regarding whether the display device 200 is connected to an earphone, the controller 250 may perform different processing flows; for different earphone modes, the controller 250 may also perform different processing procedures; meanwhile, in different earphone modes or when the earphone is not connected, the controller 250 may also perform different processing flows for different audio modes. Therefore, when the vision disorder user and the vision normal user use the display device 200 at the same time, the scheme in the embodiment of the application can provide resource playing services in multiple modes for the vision disorder user and the vision normal user according to the requirements and the selections of the users.

In addition, in the embodiment of the present application, the user selects various modes by inputting instructions to the display apparatus 200, and the inputting manner includes, but is not limited to, remote control input, voice input, and the like, where the remote control input is that the user indirectly inputs instructions to the display apparatus 200 through a remote control, and the voice input is that the user directly inputs instructions to the display apparatus 200 through voice.
