But those skilled in the art should understand that in actual use, it is also possible to display the remaining desktop thumbnails of other application services in the vertical direction of the desktop thumbnails of a certain application service, and display the remaining desktop thumbnails of other application services in the vertical direction of the desktop thumbnails of another application service. The desktop thumbnail of the sub-application service of the application service is displayed in the vertical direction. For this case, those skilled in the art can refer to the second embodiment and the corresponding content in this embodiment to set and operate the setting navigation desktop. Here No more details.

The smart TV desktop switching method of the present embodiment includes the following steps:

Step S202: The smart TV acquires information of multiple application services registered with the setting navigation desktop, and information of sub-application services under each application service.

Wherein, the information of each application service includes the information of the desktop corresponding to each application service (such as desktop thumbnail information, and/or desktop index information, and/or desktop storage location information, etc.), information of each sub-application service Information about the desktop corresponding to each sub-application service (such as desktop thumbnail information, and/or desktop index information, and/or desktop storage location information, etc.) is included.

In this embodiment, the navigation desktop is still set to be a cross-shaped navigation desktop, which is used to display desktop thumbnails corresponding to multiple application services from the horizontal direction and vertical direction, and the desktop thumbnails corresponding to the sub-application services under each application service. Sketch map. That is to say, setting the navigation desktop can not only be used to display the desktop thumbnails corresponding to multiple application services from the horizontal direction and the vertical direction, but also can be used to display the vertical direction of the desktop thumbnails corresponding to the application services displayed in the horizontal direction. to display the desktop thumbnail corresponding to the sub-application service of the application service displayed in the horizontal direction.

Step S204: According to the information of the multiple application services, the smart TV displays the desktop thumbnails of the desktops of the multiple application services in the horizontal direction according to a set format.

Wherein, the setting format can be appropriately set by those skilled in the art according to actual needs, such as setting the placement position, size, and spacing distance of each desktop thumbnail in the horizontal direction.

If the desktop information corresponding to the application service includes desktop thumbnail information, the smart TV can arrange the desktop thumbnails in the horizontal direction of the cross navigation desktop according to the set format; if the desktop information corresponding to the application service includes desktop index information, then The smart TV can obtain the corresponding desktop according to the desktop index information, and then scale the desktop according to the size and size of the set format rules, and after generating desktop thumbnails, arrange them in the horizontal direction of the cross-shaped navigation desktop according to the set format; If the information of the desktop corresponding to the application service includes the storage location information of the desktop, the smart TV can obtain the corresponding desktop from the storage location, and then zoom and arrange it in the horizontal direction of the cross-shaped navigation desktop according to a set format. Of course, it is not limited thereto, and other information used to indicate the desktop corresponding to the application service can be processed by referring to the above manner.

Step S206: The smart TV judges each application service one by one whether there is sub-application service information, if yes, execute step S208; if not, do not process.

Application services and sub-application services under application services can exist in a tree structure, that is, there may be single-level single or single-level multiple sub-application services under application services, and there may also be multi-level sub-application services. Each sub-application service in each level There may be one or more sub-application services under the application service.

Step S208: If there is a sub-application service under the application service, the smart TV displays the sub-application service of the application service in the vertical direction of the desktop thumbnail of the application service with the sub-application service according to the information of the sub-application service under the application service The desktop thumbnail image of the desktop, and then generate a set navigation desktop, which is a cross-shaped navigation desktop in this embodiment.

So far, the cross-shaped navigation desktop is completed, that is, the generation of the navigation desktop is set. It should be noted that the generation of the cross-shaped navigation desktop can not only be completed when the smart TV system is initially installed, but also can be regenerated when the application services registered with the cross-shaped navigation desktop are changed. Once the navigation desktop is set, it can be used continuously in the future, and it does not need to be generated every time the smart TV desktop is switched.

Step S210: The smart TV acquires information about various application services of the smart TV.

Wherein, the information of the application service includes but is not limited to: whether the application service has been registered with the set navigation desktop, of course, it can also include the specific information of the application service, such as the name of the application service, the function realized, the application The general information such as the service type, etc., the present invention does not limit this part of the general information.

Step S212: The smart TV judges whether each application service belongs to the application service registered with the setting navigation desktop according to the information of each application service; if yes, execute step S214; if not, execute step S216.

Step S214: If the application service belongs to the application service registered with the setting navigation desktop, the smart TV sets the status indicator of the application service as visible, and executes step S218.

Setting the status flag of the application service to be visible can indicate that when the application service is the current service and receives the return instruction sent by the control device, it will return to the set navigation desktop, which is a cross-shaped navigation desktop in this embodiment.

Step S216: If the application service does not belong to the application service registered with the setting navigation desktop, the smart TV sets the status indicator of the application service as invisible, and executes step S218.

Setting the status indicator of the application service to be invisible may indicate that when the application service is the current service and the return instruction sent by the control device is received, return to the default desktop of the smart TV.

So far, the setting of the state identification of each application service is completed. It should be noted that the setting of this status flag can not only be completed during the initial installation of the smart TV system, but also can be regenerated when the application services registered to the set navigation desktop such as the cross-shaped navigation desktop are changed. The service registers with the cross-shaped navigation desktop, or exits the registration of the current cross-shaped navigation desktop, etc. Once the status identification of the application service is set, it can be used continuously in the future, and it is not necessary to set it every time the smart TV desktop is switched.

It should also be noted that, in practical applications, steps S202-S208 and steps S210-S216, that is, the steps of generating and setting the navigation desktop and the steps of setting the status flag of the application service, can be executed in no particular order, or can be executed in parallel.

Step S218: After receiving the return instruction sent by the control device, the smart TV obtains the status identifier of the current smart TV desktop.

As mentioned above, the status identifier is used to indicate whether the current smart TV desktop returns to the set navigation desktop after receiving the return instruction sent by the control device. The desktop thumbnails corresponding to multiple application services registered with the setting navigation desktop, and the desktop thumbnails corresponding to the sub-application services under each registered application service are displayed in the vertical direction.

Preferably, the setting key is a HOME key (ie a menu key). That is, the smart TV receives the return instruction sent by the control device through the HOME key. In the Android system, the HOME key is very common, and the default behavior of pressing the HOME key is to start the default desktop of the system through an Intent (intent). In this embodiment, in order to comply with the user's usage habits, when the user uses a control device such as a remote control to control the smart TV, the button that sends the return command is also set as the HOME button, which is convenient for the user to use and improves the user experience.

Step S220: The smart TV determines to return to and display the set navigation desktop or the default desktop of the smart TV according to the status identifier of the current smart TV desktop and the return instruction.

In this embodiment, on the basis of distinguishing the state identification into visible and invisible, when the state identification of the current smart TV desktop is visible, then return and display the set navigation desktop according to the return instruction, which is ten in this embodiment. Glyph navigation desktop; when the current state of the smart TV desktop is not visible, return and display the default desktop of the smart TV according to the return instruction.

Preferably, according to the return instruction and the state identification of the current smart TV desktop, returning and displaying the set navigation desktop is realized by the system framework layer of the smart TV, including: when the smart TV determines the current smart TV desktop through the system framework layer of the smart TV When the status flag of is visible, then according to the return instruction, a broadcast message is sent to the application service corresponding to the current smart TV desktop through the system framework layer, so that the application service returns and displays the set navigation desktop after receiving the broadcast message.

In a smart TV, the hardware is at the bottom layer, the LINUX kernel and the hardware abstraction layer are placed on the upper layer of the hardware, and the system framework of the smart TV is on top of the hardware abstraction layer. The system framework of smart TV includes: application layer, framework layer, and adaptation layer. Among them, the application layer is located at the top of the smart TV system framework, providing various application services to users; the framework layer provides system libraries for the application services of the application layer, and application developers can use the system libraries and APIs provided by the framework layer to develop applications; The adaptation layer can adapt various devices of the smart TV, such as input devices, sensors, cameras, audio and video modules, displays, Ethernet, WIFI, and so on. In the above-mentioned preferred solution of this embodiment, the frame layer of the smart TV is improved, and the return and display of the set navigation desktop are realized through it, and the existing system architecture and process are utilized as much as possible to save the implementation cost of the present invention .

In addition, in order to improve the user's perception of the set navigation desktop and understand the current usage status of each application in the set navigation desktop, during the use of the current application service, the smart TV will follow the set rules to update the corresponding application on the current smart TV desktop. The service takes a screenshot of the desktop; then, after receiving the return instruction, according to the current smart TV's desktop status identifier and the return instruction, it is determined to return to the set navigation desktop, and the desktop screenshot of the application service corresponding to the current smart TV desktop is stopped; and, the The last desktop screenshot in the desktop screenshot is set as the desktop thumbnail corresponding to the application service, and is displayed in the setting navigation desktop together with other desktop thumbnails in the setting navigation desktop. Wherein, the setting rules for desktop screenshots can be appropriately set by those skilled in the art according to actual needs, such as real-time screenshots, or screenshots at set time intervals, or, through comparison and analysis of pictures, it is found that the picture changes exceed the set threshold Take screenshots etc. In this way, the desktop thumbnail image in the returned setting navigation desktop is an updated desktop thumbnail image, which can accurately reflect the current usage state of the exited application service.

In specific implementation, an optional implementation method is: setting a unique index identifier for the desktop thumbnails corresponding to each application service in the navigation desktop, that is, setting the desktop thumbnails corresponding to each application service in the navigation desktop. Thumbnails have a unique index ID. On this basis, the step of setting the last desktop screenshot among the desktop screenshots as the desktop thumbnail corresponding to the application service may include: determining the index identifier of the desktop thumbnail corresponding to the application service in setting the navigation desktop, using the desktop screenshot Update the desktop thumbnail corresponding to the index ID in the last screenshot of the desktop. Through the unique index identification method, the desktop thumbnail corresponding to the application service can be efficiently and quickly searched and updated. But not limited to this, other methods of updating the desktop thumbnails in the cross-shaped navigation desktop are also applicable, such as setting a desktop image library for each application service, storing the screenshot of the desktop in the desktop image library corresponding to the application service, and When applying the service, select a screenshot of the desktop from the desktop picture gallery to display; or, it is also possible not to update the thumbnail of the desktop.

For example, if the user is watching a certain TV series through the on-demand service registered with the setting navigation desktop, the smart TV will take screenshots of the TV series according to the setting rules, such as real-time screenshots. When the user presses the HOME button on the remote control, it is required to return to the setting navigation When the screen is on the desktop, the smart TV uses the last one in the real-time screenshot to update the desktop thumbnail of the on-demand service displayed in the previous setting navigation desktop. At this time, after returning to the setting navigation desktop, the user sees the TV series just watched Thumbnail image of the last screen.

Embodiment four

Referring to FIG. 5 , it shows a flowchart of steps of a method for switching desktops of a smart TV according to Embodiment 4 of the present invention.

In this embodiment, taking setting the navigation desktop as a cross-shaped navigation desktop as an example, the smart TV desktop switching method in this embodiment includes the following steps:

Step S302: The smart TV generates a cross-shaped navigation desktop and sets the status flags of each application service.

For the specific process of generating the cross-shaped navigation desktop and the process of setting the status flags of each application service, please refer to the descriptions of the relevant parts in Embodiment 1, Embodiment 2, and Embodiment 3, which will not be repeated here.

In this embodiment, the generated cross-shaped navigation desktop is set as shown in Figure 6. The cross-shaped navigation desktop includes five desktop thumbnails of application services arranged in parallel horizontally, namely: the signal source desktop, the search desktop, the wheel broadcast desktop, on-demand desktop, and application desktop, wherein "application" includes two sub-application services "application 1" and "application 2". In addition, in this embodiment, as an alternative to displaying the desktop thumbnails of the sub-application services in the vertical direction of the desktop thumbnails of the application services on the basis of displaying the desktop thumbnails of the application services, directly use the The desktop thumbnail displays the content of the sub-application services included in the application service, and this method is more suitable for the situation where the sub-application services can intuitively reflect their parent application services. Preferably, in this embodiment, corresponding to the desktop thumbnails of the five set application services, corresponding icons (shown in dotted line boxes) are also provided under the cross-shaped navigation desktop, which further facilitates user operations. When a desktop thumbnail is in focus, its corresponding icon is also set in focus.

In Figure 6, the signal source desktop, search desktop, carousel desktop, on-demand desktop, and application desktop arranged in sequence from left to right can be switched among each other. The number of application services, the desktop of application services can be expanded vertically. It can be seen from Figure 5 that the entire cross-shaped navigation desktop system has a clear division of labor. Compared with the single desktop of traditional TV, users are easily confused when switching desktops and cannot remember the positions of each desktop. At the same time, from the leftmost to the rightmost The desktop needs to move the focus multiple times, and there are many operating steps. On the premise of retaining the advantages of the multi-application service desktop, the cross-shaped navigation desktop can effectively reduce the confusion of the user during operation and reduce the operation steps.

Based on the setting of the cross-shaped navigation desktop shown in Figure 6, in this embodiment, the signal source desktop, the search desktop, the carousel desktop, the on-demand desktop, and the state signs of the application 1 desktop and the application 2 desktop are all set to be visible. Any one of the desktops is the current desktop, that is, when the application service corresponding to the desktop is currently being used by the user, if the user presses the set button, which is set as the HOME button in this embodiment, when the return command is input, it can return directly The cross-shaped navigation desktop of the present embodiment.

Step S304: The smart TV receives the instruction sent by the control device through the setting button, and judges whether the instruction is a return instruction corresponding to the setting button; if yes, execute step S306; Instructions are used to perform corresponding operations on the smart TV.

In this embodiment, the setting key is set as the HOME key, and when the user sends an instruction through the HOME key, subsequent logical judgment processing steps are performed. And if the user presses other buttons, corresponding processing will be carried out according to the instructions corresponding to the button pressed by the user. For example, when the user presses the "OK" button for a selected operation or application, the corresponding button will be activated. operation or application; for another example, when the user needs to uninstall a certain application service and presses a corresponding button, the application service selected by the user will be uninstalled, etc., which is not limited in the present invention.

Step S306: The smart TV determines that the indication command sent by the control device is a return command corresponding to the set button, and executes step S308.

If the user sends an instruction through the HOME key, the subsequent logic judgment process will be executed.

Step S308: the smart TV acquires the current status identifier of the smart TV desktop.

Among them, as mentioned above, if the status mark is visible, then after receiving the return command, the current smart TV desktop returns to the cross-shaped navigation desktop; otherwise, if the status mark is invisible, then when the return command is received, the current smart TV desktop The TV desktop returns to the system's default desktop.

In this embodiment, the operating system of the smart TV is set to be the Android system, and the default behavior of pressing the HOME key of the Android system is to start the desktop by means of an Intent (intent) (the desktop is not limited to the cross-shaped navigation desktop in this embodiment, Also include other desktops such as system default desktops or third-party desktops.In this embodiment, distinguish the pressing logic of the HOME key, that is, if the current desktop is any one of the above-mentioned five major application service desktops, it will be displayed when the HOME key is pressed. Cross-shaped navigation desktop, otherwise return to the default desktop according to the logic of Android. Among them, when the five major application service desktops are displayed, the service that maintains the desktop status at the framework layer of the system will mark the desktop as visible, and if the first one is opened The third-party application service will mark the third-party application service desktop as an invisible state. In this way, when the framework layer intercepts the instruction corresponding to the HOME key and performs logical processing, if the service mark is visible, the framework layer sends a broadcast. The broadcast receiver registered in the glyph navigation desktop can obtain the intention to display the cross-shaped navigation desktop and then display the cross-shaped navigation desktop, otherwise execute the Android default logic to return to the default desktop of the system from other application services.

Step S310: The smart TV determines to return to and display the cross-shaped navigation desktop or the default desktop of the smart TV according to the status identification of the current smart TV desktop and the return instruction.

Therefore, when the cross-shaped navigation desktop is displayed, the interface provided by the framework layer can first obtain the screenshot of the display status of the current smart TV desktop, and then set the screenshot to the corresponding desktop view, and set the corresponding view of the current desktop Move to the middle of the screen.

For example, assuming that the current user is using the "on-demand" application service, when the user presses the HOME key, it will return to the cross-shaped navigation desktop, and the focus and central position of the returned cross-shaped navigation desktop are both the on-demand desktop, as shown in Figure 7 .

For another example, assuming that the current user is using the sub-application service of "Application 2" under "Application", when the user presses the HOME key, it will also return to the cross-shaped navigation desktop, and the focus and center position of the returned cross-shaped navigation desktop Both are application 2 desktops, as shown in Figure 8.

On the basis of displaying the cross-shaped navigation desktop, press the left and right arrow keys to switch between different desktop thumbnail views or press the up and down keys to switch different sub-desktop views of the current desktop to the middle of the screen. When switching, calculate the horizontal and vertical distances between the position of the desktop view to be switched on the screen and the middle position of the screen, and then the parent layout moves the corresponding distance. Each view corresponds to a click event. After pressing OK, the service of the frame layer is called to notify the desktop to switch the display logic according to the index of the current desktop or the index of the sub-desktop in the form of an Intent (view). The desktop obtains the index of the target desktop and/or the index of the corresponding sub-desktop according to the Intent, and then displays different views.

For example, when the user uses the HOME key on the desktop corresponding to the currently used "search" application service to return to the cross-shaped navigation desktop, the current focus of the cross-shaped navigation desktop is on the search desktop; The focus and central position of the navigation desktop are moved to the carousel desktop. If the user presses the OK button at this time, the "carousel" application service is entered, thereby realizing the switching between the desktop and the application service, as shown in Figure 9.

Through this embodiment, on the current desktop of the application service in any cross-shaped navigation desktop, press the HOME key to return to the cross-shaped navigation desktop, and the thumbnails of the current state of the desktop corresponding to each application service appear, according to the position when actually switching Relational layout, that is, the desktops of the five major application services are arranged horizontally, and the desktops that can be expanded up and down (such as the desktop of application 1 and the desktop of application 2) are arranged up and down. The focus is on the current desktop. Press the "left/right" key to move the focus horizontally, press "OK" key to enter the selected desktop. In this embodiment, by pressing the HOME key to call out the cross-shaped navigation desktop, the user can have an overall understanding of the desktops of all application services in the cross-shaped navigation desktop, which helps the user understand the positional relationship of each desktop, and conforms to The user's consistent understanding of the HOME button can return to the unified interface, which is easy to remember, and on the premise of retaining the advantages of multiple desktops, making full use of the HOME button can effectively reduce user confusion and reduce operation steps.
