Detailed Description

To make the objects, technical solutions and advantages of the exemplary embodiments of the present application clearer, the technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is obvious that the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments.

The present application relates to a display terminal including at least two system-on-chip, and for ease of understanding, a display terminal of a multi-chip structure is described herein.

For the convenience of users, various external device interfaces are usually provided on the display device to facilitate connection of different peripheral devices or cables to implement corresponding functions. When a high-definition camera is connected to an interface of the display device, if a hardware system of the display device does not have a hardware interface of a high-pixel camera receiving the source code, data received by the camera cannot be displayed on a display screen of the display device.

Furthermore, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resources, and usually only supports video decoding with a resolution of 4K at most, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resources (usually GPU in the hardware system) to decode the network video without reducing the definition of the network video screen, and in this case, the user can only process the video chat screen by using a general-purpose processor (e.g. CPU) in the hardware system to perform soft decoding on the video.

The soft decoding is adopted to process the video chat picture, so that the data processing burden of a CPU (central processing unit) can be greatly increased, and when the data processing burden of the CPU is too heavy, the problem of picture blocking or unsmooth flow can occur. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multi-channel video calls cannot be generally implemented, and when a user wants to perform video chat with multiple other users in the same chat scene, access is blocked.

In view of the above aspects, to overcome the above drawbacks, the present application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one channel of local video).

The application layer 3912 of the a-chip may include, but is not limited to, one or more applications such as: live television applications, media center applications, and the like. It should be noted that what applications are respectively contained in the a chip and the N chip is determined according to an operating system and other designs, and the present invention does not need to make specific limitations and divisions on the applications contained in the a chip and the N chip.

The live television application program can provide live television through different signal sources. For example, a live television application may provide television signals using input from cable television, wireless network change broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

A video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. 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.

The media center application program can provide various applications for playing multimedia contents. 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.

The application program center can provide and store various application programs.

And a selector in the user interface indicating that the item is selected, the position of the selector being movable by user input to change the selection of a different item.

It should be noted that the multiple view display areas may present display screens of different hierarchies. For example, a first view display area may present video chat project content and a second view display area may present application layer project content (e.g., web page video, VOD presentations, application screens, etc.).

Optionally, the different view display areas are presented with different priorities, and the display priorities of the view display areas are different among the view display areas with different priorities. If the priority of the system layer is higher than that of the application layer, when the user uses the acquisition selector and picture switching in the application layer, the picture display of the view display area of the system layer is not blocked; and when the size and the position of the view display area of the application layer are changed according to the selection of the user, the size and the position of the view display area of the system layer are not influenced.

The display frames of the same hierarchy can also be presented, at this time, the selector can switch between the first view display area and the second view display area, and when the size and the position of the first view display area are changed, the size and the position of the second view display area can be changed along with the change.

Since the a-chip and the N-chip may have independent operating systems installed therein, there are two independent but interrelated subsystems in the display device 200. For example, Android (Android) and various APPs can be independently installed on the chip a and the chip N, so that each chip can realize a certain function, and the chip a and the chip N cooperatively realize a certain function.

On Android television equipment, for a new state of dual system, we want to show the capabilities of both systems to the user at the same time. The first controller (A chip) can be correspondingly pressed and set, mainly shows a television function, the second controller (N chip) mainly shows social contact ability of a user, and the first controller can be connected with the second controller in a data and communication interaction connection mode through a network, a serial port, a Tybe-C line, an HDMI communication mode and the like. If the second controller has an HDMI OUT channel, the first controller is connected with the second controller through HDMI, and the first controller is similar to a television in hardware and is externally connected with a set top box. As shown in fig. 8, the display content of the second controller transfers an image to the first controller through HDMI OUT, where the second controller is an HDMI input on the first controller, and the HDMI signal of the second controller is connected to the HDMI4 port of the first controller.

However, the first controller only provides tv capability, the home page with vod and info entry is on the second controller, we need to show the contents of the second controller when the user presses the home key, and the second controller jumps to the home page. The key transmission between the two systems is another module, which is not described herein, and the default key can be transmitted in the past. Since the first controller also has a home page, and the two systems simultaneously pull up the home pages of the two systems simultaneously by corresponding home page keys, there are two problems: firstly, how to coexist two homepages and only visually display one homepage; and the second is how to coordinate the relationship of the respective application displays of the two systems.

In order to solve the above problem, an embodiment of the present application provides a display device, where the display device sets a home page of a first controller as a transparent home page, and by a stack display of the transparent home page and an application display interface, a display and coordination of a dual home page of a dual system and a display and coordination of respective applications in the dual system can be achieved.

As shown in fig. 9, a display device provided in an embodiment of the present application includes:

the first controller 101 is configured to acquire a display instruction and determine whether an application displayed by the display instruction is located in the first controller.

And the second controller 201 is configured to receive the display instruction output by the first controller through the physical connection line and display the application interface according to the display instruction.

If the application displayed by the display instruction is located in the first controller, directly displaying an application interface, and displaying the application interface and a display interface of the second controller in a stacking manner; and if the application displayed by the display instruction is positioned on the second controller, the first controller switches the homepage of the application to the transparent homepage, informs the second controller to display the application interface, switches the signal source channel, and displays the transparent homepage and the application display interface of the second controller in a stacking manner.

A display 301 configured to display image content.

For convenience of description, the processor 310 in fig. 4 and 5 corresponds to the first controller 101 in fig. 9, and the processor 210 in fig. 4 and 5 corresponds to the second controller 201 in fig. 9, and will not be described below.

In this example, the first controller 101 includes an obtaining module 101-1 and a control module 101-2, and the obtaining module 101-1 is configured to obtain a display instruction. Namely, the user can send a display instruction through a remote controller key, and the acquisition module 101-1 receives the display instruction sent by the user. If the user presses a home page key, the home page is displayed; the user presses the key application open, i.e. to open an application of a certain system.

When the obtaining module 101-1 of the first controller 101 obtains the display instruction, the display instruction may be to display a home page, or to display the first controller application, or to display the second controller application, because the home page of the vod and info portal is on the second controller, when the user presses the home page key, the user wants to display the home page of the second controller, so as to distinguish whether the application displayed by the display instruction is located on the second controller or on the first controller by determining whether the application displayed by the display instruction is located on the first controller.

The control module 101-2 determines whether the displayed application is located in the first controller 101 or the second controller 201 according to the received display instruction, and performs a different control instruction therefor.

The second controller 201 includes a receiving module 201-1 and an application control module 201-2, the receiving module 201-1 is configured to receive a display instruction sent by the first controller 101, and after the receiving module 201-1 receives the display instruction, the display instruction may be a display homepage or a display of the second controller application, so that the homepage or an application interface of the second controller is switched by the application control module 201-2.

If it is determined that the application to be displayed is located on the second controller, that is, the user wants to see the application display interface of the second controller, it is necessary to switch the home page of the first controller to a transparent home page through which the application display interface of the second controller is displayed. The application display interface of the second controller may be a home interface and may also be an application display interface.

When a user presses a homepage key, namely a display instruction is a homepage display instruction, the first controller switches the homepage to a transparent homepage, namely an interface of the second controller can be seen through the transparent homepage; then the first controller informs the second controller to switch to the homepage interface, namely informs the second controller to pull up the homepage or switch the homepage to the foreground; then the first controller switches the signal source channel of the first controller to a corresponding HDMI channel, that is, the display content of the second controller is transferred to the first controller. At this time, the transparent homepage of the first controller and the homepage interface of the second controller are displayed in a stacked manner, the transparent homepage is in the front, the homepage interface of the second controller is in the rear, and the homepage of the first controller is the transparent homepage, so that the homepage interface of the second controller can be displayed through the transparent homepage, and the user sees the homepage content of the second controller.

When a user presses a control key (up-down, left-right and the like) on a homepage, namely a system display is a homepage interface, but when the homepage interface is operated up, down, left, right and the like through a remote controller, control key information is firstly sent to a transparent homepage of a first controller, the transparent homepage receives the control key information and then forwards the control key information to a second controller, the second controller receives the control key information forwarded by the first controller and directly sends the control key information to the homepage, and the homepage interface carries out up-down, left-right and the like browsing operations according to the control key information. Since the homepage of the first controller is a transparent homepage, although the first controller is actually operated, the homepage of the first controller is consistent with the homepage of the second controller which is directly operated from the user perspective, and the use experience of the user is improved.

When a user wants to open a certain application on the second controller, namely the display instruction is the second controller application display instruction, the first controller switches the homepage of the first controller to the transparent homepage, then the first controller informs the second controller to start the application, the homepage of the second controller is switched to the rear of the application display interface, then the first controller switches the signal source channel of the first controller to be the corresponding HDMI channel, and the application content of the second controller is transmitted to the first controller. At this time, the transparent homepage of the first controller and the application display interface are displayed in a stacked manner, the transparent homepage is in front, the application display interface of the second controller is in rear, the application display interface of the second controller can be displayed through the transparent homepage, and the user sees the application display interface of the second controller.

When the second controller is applied to displaying the application interface, the full-screen display may be performed, or the non-full-screen display may be performed, for example, when the arcade App at the second controller end is started, a user generally wants the application display interface of the arcade App to be the full-screen display, at this time, the homepage of the first controller needs to be switched to the transparent homepage, the transparent homepage and the arcade App display interface are displayed in a stacked manner, and the arcade App display interface can be displayed on the first controller through the transparent homepage, so that the full-screen display of the arcade App is realized.

When the application display interface of the second controller is not full screen, if a video chat application at the second controller end is started, the chat window only occupies a part of the screen, the homepage of the first controller can be switched to a partial transparent homepage, the partial transparent homepage and the non-full screen application display interface are displayed in a stacked mode, namely the partial transparent homepage is in the front, the non-full screen application display interface is in the rear, the non-full screen application display interface is displayed through the transparent part of the partial transparent homepage, meanwhile, the non-transparent part of the partial transparent homepage can display partial content of the homepage of the first controller, and multiple functions are displayed.

When the application display interface of the second controller is not full screen, the homepage of the first controller can be switched to the transparent homepage, and the transparent homepage, the non-full screen application display interface and the homepage of the second controller are displayed in a stacked mode, namely the transparent homepage is in the front, the non-full screen application display interface is in the middle, and the second controller homepage is in the rear.

If the application to be displayed is determined to be located on the first controller, namely the user wants to see the application display interface of the first controller, the first controller directly starts the application and displays the application display interface. When the first controller application is started, the first controller application is started on the homepage of the second controller, and the application interface can be a full-screen application display interface or a non-full-screen application display interface.

For the application of the full-screen application display interface on the first controller, the first controller is informed to start the application, the HDMI channel of the first controller is cut away, and the sound and the like of the application on the second controller are prevented from being transmitted to the first controller. In the scene, an application full-screen display interface, a first controller homepage and a second controller application display interface are displayed in a stacked mode, the application full-screen display interface is in the front, the first controller homepage is in the middle, the second controller application display interface is in the rear, and application contents on the first controller are directly displayed on a screen. In this scenario, since the first controller homepage is blocked by applying the full-screen display interface, the first controller homepage may be a transparent homepage or a non-transparent homepage.

And for the application of the non-full-screen application display interface on the first controller, informing the first controller to start the application, switching the home page of the first controller to the transparent home page, and displaying the non-full-screen application display interface, the transparent home page and the display interface of the second controller in a stacking manner.
