In order to solve the technical problem, the embodiment of the application discloses the following technical scheme:
in a first aspect, an embodiment of the present application discloses a display device, including:
a display configured to display image content;
a second controller comprising a second control schedule configured to receive an application jump instruction and determine whether a jump-to application is located at the second controller according to the application jump instruction; if the jumped application is located in the second controller, directly starting the jumped application; if the application of the jump is not positioned in the second controller, sending a scheduling instruction;
a first controller including a first control schedule configured to receive a scheduling instruction sent by the second control schedule, and to start a skipped application according to the scheduling instruction.
In a second aspect, an embodiment of the present application further provides a control method for application jump, which is applied to the display device in the first aspect, and the method includes:
a second control schedule of a second controller receives an application jump instruction and judges whether the jumped application is positioned in the second controller or not according to the application jump instruction;

if the application of the jump is positioned in a first controller, the second control schedule sends a scheduling instruction to the first control schedule of the first controller; and the first control scheduling starts the jumped application according to the scheduling instruction.
Compared with the prior art, the beneficial effect of this application is:
aiming at the display equipment with a dual-system structure, the second controller comprises a second control schedule, the second control schedule receives an application jump instruction, and whether the jumped application is positioned in the second controller is judged according to the application jump instruction; if the jumped application is located in the second controller, directly starting the jumped application; if the application of the jump is not positioned in the second controller, sending a scheduling instruction to the first controller; the first controller comprises a first control schedule, the first control schedule receives a scheduling instruction output by the second control schedule, and the skipped application is started according to the scheduling instruction. According to the method and the device, the application jump between the second controller and the first controller is realized by sending the scheduling instruction, so that the mutual switching of the applications of the two parties on the double systems is realized, namely, when the second controller application jumps to the first controller application, the first controller directly operates the second controller application to jump to the first controller application from the HDMI after receiving the scheduling instruction, the jump is similar to the common application jump, a user cannot feel content services provided by the two systems, and therefore the application switching performance between the double systems and the use experience of the user can be greatly improved.

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 concept to which the present application relates will be first explained below with reference to the drawings. It should be noted that the following descriptions of the concepts are only for the purpose of facilitating understanding of the contents of the present application, and do not represent limitations on the scope of the present application.

Here, 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, which will not be described below.
In order to realize application jump of a first controller and a second controller, a scheduling service is provided at each end of a dual system, and a general scheduling interface is provided for mutual jump between applications built in a television, namely a first control schedule is set at the first controller, a second control schedule is set at the second controller, and the first control schedule and the second control schedule are connected with each other. When the first controller monitors an application jump instruction, the application jump instruction is sent to the first control dispatch, if a certain application 101-1 of the first controller is displayed, a user wants to jump to another application through a remote controller, the first controller generates the application jump instruction, the application jump instruction is sent to the first control dispatch, and application jump is achieved through the first control dispatch.
Similarly, when the second controller monitors an application jump instruction, the application jump instruction is sent to the second control schedule, if a certain application on the second controller is being displayed, and a user wants to jump to another application through the remote controller, the second controller generates the application jump instruction, sends the application jump instruction to the second control schedule, and realizes application jump through the second control schedule.
When the user performs application jumping, the user may jump to the same application or different applications, for example, a certain application 101-1 displaying the first controller, the user may want to jump to another application of the first controller, or the user may want to jump to another application of the second controller. Therefore, the first control schedule 101-2 is required to determine whether the application to be jumped is located at the first controller according to the application jump instruction.
The first control schedule 101-2 may query whether the first controller 101 has an application to be skipped according to the application interface, and the second control schedule 201-1 may also query whether the second controller 201 has an application to be skipped according to the application interface, that is, the system schedule may query the application at the home terminal. If the first control schedule 101-2 inquires that the application to be jumped is located in the first controller 101 according to the application jump instruction, the application jump instruction is a jump of the application between the same end systems, and a mature solution is provided.
If the first control schedule 101-2 does not inquire that the application to be jumped exists in the first controller 101 according to the application jump instruction, the application to be jumped may be located in the second controller 201, at this time, the first control schedule 101-2 sends an inquiry instruction to the second control schedule 201-1, the second control schedule 201-1 inquires whether the application to be jumped exists in the second controller 201 according to the inquiry instruction, the second control schedule 201-1 inquires that the application to be jumped is located in the second controller 201, the first control schedule 101-2 item of the second control schedule 201-1 sends a schedule instruction, and the second control schedule 201-1 opens the application 201-2 according to the schedule instruction.
As shown in fig. 10, when the user starts the application AppN of the first controller 101, and wants to jump to the application AppN1 through the remote controller, the generated application jump instruction is sent to the first control schedule 101-2, the first control schedule 101-2 queries that the application AppN1 is located in the first controller 101 according to the application jump instruction, and the first control schedule 101-2 directly sends an application start instruction to the local application AppN1, so as to directly start the application AppN1 of the first controller 101.
If a user starts an application ApPN of a first controller 101 and wants to jump to the application AppA through a remote controller, a generated application jump instruction is sent to a first control schedule 101-2, the first control schedule 101-2 inquires that the application AppA is not located in the first controller 101 according to the application jump instruction, the application AppA may be located in a second controller 201, the first control schedule 101-2 sends a scheduling instruction to a second control schedule 201-1, and the application AppA is started through the second control schedule 201-1.
The first control dispatch 101-2 sends an inquiry instruction to the second control dispatch 201-1, the second control dispatch 201-1 inquires that the application AppA is located in the second controller 201, the second control dispatch 201-1 feeds back to the first control dispatch 101-2, then the first control dispatch 101-2 sends a dispatch instruction to the second control dispatch 201-1, the second control dispatch 201-1 determines the application to be jumped according to the dispatch instruction, the application AppA is started through the second control dispatch 201-1, meanwhile, the second control dispatch 201-1 sends a switching instruction to the first controller 101, a signal source is switched to an HDMI signal, and the content of the jumped application AppA is displayed.
In this example, the first controller provides a television capability, can play the content of the ATV/DTV/HDMI physical channel, and collectively refer to the physical channel and the Android channel as a signal source, and the switching operation between them is referred to as signal source switching. When the application on the first controller jumps to the application on the second controller, namely the application AppA of a certain application AppN of the first controller jumps to the second controller is converted into the application LiveTV which jumps to the first controller from the application AppN and provides HDMI signal input, therefore, through the display device provided by the application, the application jump between the two systems on the first controller is the switching of two common applications, LiveTV and the application AppN.
The application starts the application on the second controller through the scheduler and then informs the first controller to switch to the signal source HDMI4 because HDMI4 accesses HDMI OUT of the second controller, thus displaying the content on the second controller. The application starting on the second controller is informed firstly, so that the user is prevented from seeing the process that the second controller is switched to the AppA to be skipped from a homepage or other application interfaces, the HDMI signal from the AppN to the LiveTV is visually stopped, and then the process that one application of the first controller is switched to the AppA is avoided, the situation that the content of the AppA to be skipped can be seen after one scene passing is ensured, and the use experience of the user is greatly improved.
The application transferred to the second controller on the first controller is only to switch the current channel to the HDMI, and since switching from the simple Android APK to the signal source is similar to switching to a Video playing view, and since the signals such as the HDMI are displayed on a Video layer in a common way, the phenomena of screen flashing, screen flashing and the like which are generated by unstable connection of the HDMI signal in the initial stage inevitably occur, namely when the application ApPN on the first controller jumps to the application AppA on the second controller, due to the unstable signal in the initial stage of the HDMI, the screen flashing and the screen flashing easily occur when the application AppA content is displayed, and the use experience of a user is influenced.
In order to solve the problem, a gray mask is set in the first controller 101, when the first controller 101 receives an application signal of the second controller 201, the first controller 101 shields the application signal through the gray mask, the shielded application signal is not displayed on the first controller 101, that is, the first controller 101 displays a black screen, after the application signal received by the first controller 101 is stable, the gray mask is removed, the first controller 101 displays the application signal sent by the second controller 201, so that a user cannot see the problems of screen flashing and screen blooming when jumping between applications, and the use experience of the user is greatly improved.
The HDMI signal transmitted by the second controller 201 to the first controller 101 includes three states: the method comprises the steps of signal connection, signal decoding and signal stabilization, wherein when the first controller 101 receives the signal connection of the HDMI signal, the signal is superposed on a page of the applied AppA through a gray shade in the signal decoding state, the content of the applied AppA is not displayed on the first controller 101, and when the HDMI signal state is the signal stabilization state, the gray shade is removed, so that the content of the applied AppA is displayed on the first controller 101, and the jump of the applied AppA from the first controller 101 to the second controller 201 by the applied ApPN is realized.
When the application is jumped, if the application to be jumped is abnormal or the system where the application to be jumped is abnormal, the jump between the applications may not be realized, but the user cannot know that the application or the system is abnormal, and may wait for a long time to jump the application, which affects the user experience.
In order to solve the problem, the application jump preset time is set, if the application jump time exceeds the preset time, it is indicated that an application to be jumped or a system where the application to be jumped is abnormal, at this moment, the first controller 101 pops up prompt information to prompt a user to retry or power-off retry, and the user is prevented from waiting for too long time.
As shown in fig. 11, if the user starts the application AppN of the first controller 101, but wants to jump to the application AppN1 of the first controller 101 through the remote controller, the application jump time is recorded, and if the application jump time exceeds a preset time, it indicates that the application AppN1 is abnormal, or the first controller 101 is abnormal, and the jump of the application AppN1 cannot be realized, at this time, the first control schedule 101-2 generates a timeout instruction and sends the timeout instruction to the notification center of the first controller 101, and the notification center pops up prompt information according to the timeout instruction to prompt the user to retry or retry power failure.
If the user starts the application ApPN of the first controller 101, but the user wants to jump to the application AppA of the second controller 201 through the remote controller, the application jump time is recorded, if the application jump time exceeds the preset time, the application AppA is abnormal, or the second controller 201 where the application AppA is located is abnormal, the jump of the application AppA cannot be realized, at this moment, the second control schedule 201-1 sends a timeout instruction to the first control schedule 101-2, the first control schedule 101-2 transmits the timeout instruction to a notification center of the first controller 101, and the notification center pops out prompt information according to the timeout instruction to prompt the user to retry or power failure retry.
Similarly, as shown in fig. 12, when the user starts the application apa of the second controller, and wants to jump to the application apa 1 through the remote controller, the generated application jump instruction is sent to the second control schedule 201-1, and the second control schedule 201-1 queries that the application apa 1 is located in the second controller 201 according to the application jump instruction, that is, the application apa and the application apa 1 belong to application jump between the same systems, the second control schedule 201-1 directly sends an application start instruction to the application apa 1 at the local end, and directly starts the application apa 1 of the second controller 201.
If a user starts the application AppA of the second controller 201 and wants to jump to the application AppN through a remote controller, the generated application jumps to the second control schedule 201-1, the second control schedule 201-1 inquires that the application AppN is not located in the second controller 201 according to the application jump instruction, the application AppN may be located in the first controller 101, the second control schedule 201-1 sends an inquiry instruction to the first control schedule 101-2, and the first control schedule 101-2 inquires that the application AppN is located behind the first controller 101, namely the current application and the application to be jumped are located in different systems. And the first control dispatch 101-2 feeds back to the second control dispatch, the second control dispatch 201-1 sends a dispatch instruction to the first control dispatch 101-2, the first control dispatch 101-2 determines an application to be jumped according to the dispatch instruction, the application ApPnN is started through the first control dispatch 101-2, and the content of the application AppN after the jump is displayed.
The application AppA of the second controller 201 notifies the first control schedule 101-2 to start the application AppN of the first controller 101 through the second control schedule 201-1, that is, the first control schedule 101-2 directly operates the application AppN to jump to the first controller 101 after receiving the schedule instruction, which is similar to ordinary application jump. However, there is a problem that if the application on the second controller 201 is playing music or watching video, and at this time, when the current application jumps to the application on the first controller 101, it is not desirable that the current application on the second controller 201 continues the music or video playing action, so it is necessary to think of triggering the onPause lifecycle of the current application on the second controller 201 to stop playing audio or video.
In order to solve the above problem, an Activity is set on the second control schedule 201-1, and the Activity can trigger the lifecycle of the current application of the second controller 201 to control the start and stop of the current application. Specifically, an Activity is made in the second control schedule 201-1, and when the user jumps from the current application of the second controller 201 to the application of the first controller 101, the second control schedule 201-1 controls the current application to stop playing audio and video through the Activity.
Activity translates directly into 'Activity', and more in android is a representative screen, which is one of four large components of android, an important constituent unit and provides a visual interface for interaction with a user, and most Apps are composed of multiple screens. The Android system uses tasks to store Activities, which can be understood as Activity stacks, namely last-in first-out, when one Actity starts another Actity, the second Actity is pressed into the stack of the first Actity, the two Activities are placed in the same Task, when a backspace key is pressed, the second Actity is popped from the stack, and the first Actity returns to the top of the stack, namely the current screen is displayed.
Activity lifecycle is: the onGreate method is called when Activity is first created, then onStart when displayed to the user, and the onResume method is called if Activity is to be placed in the foreground, at which time Activity is at the top of the stack. When another Activity overrides the current Activity, this time the onPause method is called to save the data of the previous Activity. At this point, invoking the onStop method stops the Activity if you want the previous Activity not to be displayed any more, but may invoke the onResume method if you want to get back to the foreground, get focus again. After onStop, the onDestory method may be called to destroy the Activity, which may be closed by finish the last time the Activity was called. When memory resources are scarce, it is possible to kill the process with Activity in onPause, but this extreme case is rare.
Based on the Activity lifecycle, the created Activity can trigger the onPause lifecycle of the current application of the second controller 201, pause the current application, stop playing the audio and video, and display the content of the application to be skipped by the first controller 101.
If the user wants to jump back to the current application apa after jumping to the application AppN of the first controller 101 from the current application APPA, the Activity can be removed, and the content of the current application apa is displayed again. Specifically, as shown in fig. 13, when the user wants to jump back to the current application of the second controller 201, the user sends an application jump instruction to the first control schedule 101-2, because the current application is located in the second controller 201, the first control schedule 101-2 sends a schedule instruction to the second control schedule 201-1, and when the second control schedule 201-1 receives the schedule instruction, the Activity is removed, the onResume lifecycle of the current application of the second controller 201 is triggered, the current application is restarted, and audio and video are continuously played.
Because the current application is located in the second controller 201, after the current application is restarted, the second control schedule 201-1 sends a signal source switching instruction to the first control schedule 101-2, and the first control schedule 101-2 switches the signal source to the HDMI channel according to the signal source switching instruction, so as to display the current application content.
The display device provided by the embodiment of the application is provided with a first control schedule and a second control schedule respectively on a first controller and a second controller, monitors whether an application jump instruction exists in the first controller and the second controller in real time, and sends the application jump instruction to the first control schedule if the application jump instruction exists in the first controller; after receiving an application jump instruction, a first control schedule inquires whether an application to be jumped is located in a first controller according to the application jump instruction, if the application to be jumped is located in the first controller, the application belongs to application jump between the same system ends, and the first controller directly starts the application to be jumped; if the application to be jumped is not located in the first controller, the first control schedule sends a query instruction to the second control schedule, whether the application to be jumped is located in the second controller is queried through the second control schedule, if the application to be jumped is located in the second controller, the first control schedule sends a scheduling instruction to the second control schedule, the second control schedule starts the application to be jumped according to the scheduling instruction, meanwhile, a switching instruction is sent to the first control schedule, the first control schedule switches a signal source HDMI4 according to the switching instruction, the content of the application to be jumped is displayed, and application skipping between different systems is achieved. According to the display equipment, jumping between different systems is converted into switching between two common applications on the first controller through scheduling of different ends, namely switching between the LiveTV and the applications on the first controller, and a user cannot feel content services provided by the two systems, so that switching performance of the applications between the two social television systems and user experience are greatly improved.
If the second controller has an application jump instruction, the application jump instruction is sent to the second controller for scheduling; after the second controller schedules and receives an application jump instruction, whether an application to be jumped is located in the second controller or not is inquired according to the application jump instruction, if the application to be jumped is located in the second controller, the application belongs to application jump between the same system ends, and the second controller directly starts the application to be jumped; if the application to be jumped is not located in the second controller, the second controller schedules and sends a query instruction to the first controller, whether the application to be jumped is located in the first controller is queried through the scheduling of the first controller, if the application to be jumped is located in the first controller, the second controller schedules and sends a scheduling instruction to the first controller, the first controller schedules and starts to jump to the application according to the scheduling instruction, the content of the application to be jumped is displayed, and the application jump among different systems is achieved. According to the control method, the jump between different systems is converted into the switching of two common applications on the first controller through the scheduling of different ends, namely the switching of the applications on the HDMI and the first controller, and a user cannot feel the content service provided by the two systems, so that the switching performance of the applications between the two social television systems and the use experience of the user are greatly improved.
And the Activity can be set in the second control schedule, and when the user jumps from the second controller media application to the first controller application, the second control schedule starts the Activity, triggers the onPause life cycle of the current media application, and naturally pauses the current media application. When the user wants to jump back to the media application from the first controller application, the Activity is removed, the onResume life cycle of the media application is executed, the current media is continuously played, the situation that the user restarts the media application and reloads the audio and the video is avoided, and the use experience of the user is greatly improved.
