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.

Since the functions of the operating system 3911 of the a chip are similar to those of the operating system 2911 of the N chip, reference may be made to the operating system 2911 for relevant points, and details are not repeated here.

As shown in fig. 6b, the application layer of the display device contains various applications that can be executed at the display device 200.

For example, a live television application may provide television signals using input from cable television, radio 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.

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.

When the dual systems are started simultaneously, the startup time sequence is definitely asynchronous due to the difference of hardware and software structures at two ends of the dual systems, and therefore, the startup state synchronization of the key nodes needs to be ensured, so that a user can normally operate the functions of the main system N and the auxiliary system A when entering the main system.

In order to solve the above problem, an embodiment of the present application provides a display device, where a synchronization point and a strict synchronization point are defined, and a start process of a primary system N and a secondary system a is controlled according to the synchronization point or the strict synchronization point, so as to ensure synchronization of start processes of the primary system N and the secondary system a.

As shown in fig. 8, which is a flowchart of starting a key node for an Android system, from power-on to system start, the Android system goes through a series of stages in the diagram, and finally the system starts up, and a homepage is entered to allow a user to operate.

In the dual-system startup, because the display device is on the main system N, the auxiliary system is ensured to be started up when the main system N enters the main system, so that the user can use the functions of the main system N and the auxiliary system a at the same time when entering the system. Therefore, a synchronization mechanism is needed to synchronize the start-up completion status of the secondary system a to the primary system N, where synchronization is only needed once. However, in the scenes of starting up for the first time, recovering from factory and the like, the initialized progress information needs to be displayed on the main system N, the current station entering of the system initialization needs to be displayed in real time, and the system starting process needs to be synchronized.

According to the starting process of the Android system, a key point is selected for dotting in the Android starting process, which is called as a synchronization point, the starting progress displayed by the first application of the system is default to 100%, the key points in the starting stage are distributed according to the proportion, the set attribute sys.

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

the first controller 101, including the first state synchronization process 101-1, is configured to obtain current startup state information of the first controller 101.

The second controller 201, which includes a second state synchronization process 201-2, is configured to acquire current startup state information of the second controller 201 and transmit the current startup state information of the second controller 201 to the first state synchronization process.

Wherein, the first state synchronization process 101-1 determines whether the current detection point is a synchronization point or a strict synchronization point according to the current startup state information of the first controller 101 and the current startup state information of the second controller 201; if the current detection point is a synchronization point, continuing to execute the starting process of the first controller and the second controller; if the current detection point is a strict synchronization point, the starting process of the first controller or the second controller is suspended until the starting states of the first controller and the second controller are synchronized.

A display 301 configured to display image content.

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.

On Android television equipment, aiming at a new state of a social dual system, in order to realize the start synchronization of the two systems, a first state synchronization process (high system _ sync process) is arranged at a first controller end, a second state synchronization process (high system _ sync process) is arranged at a second controller end, and starting can be carried out. The first controller 101 and the second controller 201 communicate with each other by calling the process 101-2(HIRPCServer process), and the first controller 101 is responsible for displaying the content, so the first controller 101 needs to know the percentage of the second controller 201 that is activated to determine whether to let the main system enter the system and display the homepage.

As shown in fig. 10, the first state synchronization process 101-1 actively queries the percentage of the second controller 201 to be started, and then sets a property sys.b.startup.progress.percent to indicate the current starting progress of the second controller 201, so that the starting stage data of the second controller 201 can be obtained at the first controller 101. Specifically, the first state synchronization process 101-1 sends an inquiry instruction to the second state synchronization process 201-2 through the calling module 101-2, and the inquiry module 201-1 obtains the current start state information of the second controller 201 in the second state synchronization process 201-2 according to the inquiry instruction.

The starting modes of the Android system include the following modes:

on Android television equipment, a general starting mode and a recovery mode are concerned, the general starting mode is a scene which is used most, and a user normally enters a main system to use various functions. The recovery mode is an update mode of the system through which OTA upgrades of the system are made. In the process of starting progress synchronization, the progress of two ends needs to be synchronized, but the systems at the two ends still operate normally, however, in some scenarios, strict synchronization is needed, the systems stop in the state and do not go down continuously, and the systems do not go down together until the synchronous states at the two ends are all the time, and this point is defined as a "strict synchronization point". The starting of the Android system is divided into a plurality of scenes, such as the first starting of a main system or the first starting of factory restoration, the non-first normal starting of the main system, the starting synchronization of a main system STR, the starting in a recovery mode and the like.

(1) The first controller 101 is first started or factory restored first.

For a scene that the first controller 101 is started for the first time or is restored to factory first start, the start information of the second controller 201 is synchronized to the first controller 101 according to the dotting synchronization, and the current initialization progress of the first controller 101 and the second controller 201 is displayed by the first controller 101. Although there are two systems, it is only one device for the user and two progress bars cannot be displayed, so it is necessary to simultaneously display the start-up progress information of the auxiliary second controller 201 and the start-up progress information of the first controller 101 on one progress bar, the percentage display scheme may simultaneously display the progress information of the first controller 101 and the second controller 201, the odd number displayed on the progress bar may be assigned to the second controller 201, and the even number may be assigned to the first controller 101.

And for the scene of the first time starting or the first time starting of the factory restoration of the main system, defining a dotting position in the starting process of the system as a synchronization point. The system initialization must be strictly synchronized to enter the first controller 101, so as to prevent the first controller 101 from entering the system after the initialization is completed, and the second controller 201 is not yet completed, so that a point where the current start-up progress displayed by the first controller 101 is 100% is defined as a strict synchronization point.

The percentage display scheme can not only display the progress information of the first controller 101 and the second controller 201 at the same time, but also judge the current problem system and the problem position according to the progress information if a certain system has a problem.

The odd number displayed on the progress bar displayed by the first controller 101 is allocated to the second controller 201, the even number is allocated to the first controller 101, the first state synchronization process 101-1 obtains the current progress value percentage displayed by the first controller 101, calculates to obtain the next progress value next _ percentage (next _ percentage +1), and judges whether the next progress value next _ percentage is an odd number or an even number.

If the next progress value next _ percentage is an odd number, it indicates that the progress information of the second controller 201 is to be acquired, and then it is determined whether the progress information of the second controller 201 is the same as the next progress value next _ percentage, if the progress information of the second controller 201 is not less than the next progress value next _ percentage, it indicates that the second controller 201 is normally started, and the currently displayed progress information is the starting progress of the second controller 201 and is the next _ percentage; if the progress information of the second controller 201 is smaller than the next progress value next _ percent, it indicates that the start process of the second controller 201 is blocked, and at this time, the progress information displayed on the interface of the first controller 101 is an even number of percent, so that it can be determined that the second controller 201 has a problem, and the place where the problem is the next _ percent does not go, and needs to be processed.

If the next progress value next _ percent is an even number, it is indicated that the progress information of the first controller 101 is to be acquired, then whether the progress information of the first controller 101 is the same as the next progress value next _ percent is judged, if the progress information of the first controller 101 is not smaller than the next progress value next _ percent, it is indicated that the first controller 101 is normally started, the currently displayed progress information is the starting progress of the first controller 101, and the value is the next _ percent; if the progress information of the first controller 101 is smaller than the next progress value next _ percent, it indicates that the start process of the first controller 101 is blocked, and at this time, the progress information displayed on the interface of the first controller 101 is an odd number of percent, so it can be determined that the first controller 101 has a problem, and the problem is not processed at the next _ percent.

Thus, for a scene in which the first controller 101 is started for the first time or restored to factory first start, the progress value percentage currently displayed by the first controller 101 is obtained, the next progress value next _ percentage is obtained through calculation, the starting progress value of the second controller 201 or the first controller 101 is obtained according to the parity of the next progress value next _ percentage, and then the starting progress value of the second controller 201 or the first controller 101 is compared with the next progress value next _ percentage to determine whether the second controller 201 or the first controller 101 has a problem.

(2) The first controller 101 is not normally started for the first time.

For a scenario that the first controller 101 is not normally started for the first time, it is determined whether the first controller 101 is normally started for the first time, if the first controller 101 is normally started for the first time, it is determined whether the first controller 101 is started completely, if the first controller 101 is not started completely, it is determined that a current detection point is a synchronization point, and if the first controller 101 is started completely, it is determined that the current detection point is a strict synchronization point.

For the starting scenario, when the first controller 101 finishes starting and is about to enter the system, it is necessary to wait for the completion of starting of the second controller 201, so as to ensure that the user can use the functions of the first controller 101 and the second controller 201 after entering the system, therefore, when the first controller 101 finishes starting, the bootstrapation is not exited, and it is detected that the first controller 101 end synchronization process hisystem _ sync is queried from the second controller 201 until the starting progress of the second controller 201 is 100%, that is, the second controller 201 can enter the system when the system.b.startup.progress is 100, so as to ensure that the second controller 201 also finishes starting. Therefore, for this scenario, defining the dotting point in the system startup process as the synchronization point, the real-time startup state of the second controller 201 can be known. The system startup completion must be strictly synchronized to prevent the first controller 101 from entering the system after startup completion, and the second controller 201 has not yet completed startup, so the startup completion of the first controller 101 is defined as a strict synchronization point.

When detecting that the second controller 201 is not started completely, that is, the current detection point is the synchronization point, continuing to execute the starting process of the first controller 101 and the second controller 201; when the completion of the startup of the second controller 201 is detected, that is, when the current detection point is the strict synchronization point, the startup process of the first controller 101 or the second controller 201 is suspended until the startup states of the first controller 101 and the second controller 201 are synchronized.

(3) The first controller 101STR is powered on.

In a scenario of STR startup (hibernation startup) of the first controller 101, it is determined whether the first controller 101 is STR startup, if the first controller 101 is STR startup, it is determined whether STR startup of the first controller 101 is completed, if STR startup of the first controller 101 is not completed, it is determined that a current detection point is a synchronization point, and if STR startup of the first controller 101 is completed, it is determined that the current detection point is a strict synchronization point.

When the two systems are started up simultaneously in an STR mode, the first controller 101 needs to obtain the starting progress of the second controller 201 through a state synchronization process hisystem _ sync (a first state synchronization process 101-1 and a second state synchronization process 201-2), and when the second controller 201 is started up, the shielding of the first controller 101 is removed, so that the second controller 201 can be started up completely. Therefore, for this scenario, the start time of the system STR is defined as a synchronization point. The two systems STR start-up completion must be synchronized to prevent STR start-up completion of the second controller 201, while STR start-up of the second controller 201 is not completed, and therefore, the STR start-up completion point of the first controller 101 is defined as a strict synchronization point.

When detecting that the STR of the first controller 101 is not started completely, that is, the current detection point is the synchronization point, continuing to execute the starting process of the first controller 101 and the second controller 201; when it is detected that the STR startup of the first controller 101 is completed, that is, the current detection point is the strict synchronization point, the startup procedure of the first controller 101 or the second controller 201 is suspended until the startup states of the first controller 101 and the second controller 201 are synchronized.

(4) Start in recovery mode.

For a scenario that two systems are in a recovery mode at the same time, it is determined whether the first controller 101 and the second controller 201 are both started in the recovery mode, if the first controller 101 and the second controller 201 are both started in the recovery mode, it is determined whether the first controller 101 or the second controller 201 succeeds in checking, if the first controller 101 or the second controller 201 fails in checking, it is determined that a current detection point is a synchronization point, and if the first controller 101 or the second controller 201 succeeds in checking, it is determined that the current detection point is a strict synchronization point.

When two systems are in Recovery mode at the same time, the first controller 101 needs to query the start information, the check information and the installation information of the second controller 201 through a state synchronization process hisystem _ sync (a first state synchronization process 101-1 and a second state synchronization process 201-2), so that the start synchronization of the two systems can be ensured. Therefore, for this scenario, synchronization of the system startup process, synchronization of the installation progress, and synchronization of installation completion are defined as synchronization points. The two systems must be successfully checked at the same time to perform the installation action at the same time, and both ends must be successfully installed at the same time to enter the restart process, so that the successful check of the first controller 101 or the second controller 201 and the successful installation of the first controller 101 or the second controller 201 are defined as strict synchronization points, and the two strict synchronization points must wait for each other.

When detecting that the first controller 101 or the second controller 201 is not successfully checked and the first controller 101 or the second controller 201 is not successfully installed, that is, when the current detection point is the synchronization point, continuing to execute the starting process of the first controller 101 and the second controller 201; when the first controller 101 or the second controller 201 is detected to be successfully checked and the first controller 101 or the second controller 201 is successfully installed, that is, when the current detection point is the strict synchronization point, the startup process of the first controller 101 or the second controller 201 is suspended until the startup states of the first controller 101 and the second controller 201 are synchronized.

When the current detection point is the synchronization point, it is described that the first controller 101 and the second controller 201 are both executing the startup procedure and do not reach the system entry level, so the startup procedure of the first controller 101 and the second controller 201 is continuously executed.

When the current detection point is the strict synchronization point, it indicates that the first controller 101 or the second controller 201 has been started completely, or successfully verified, or successfully installed, and the other system may reach the strict synchronization point, so that the system that has reached the strict synchronization point is suspended, and the start process of the other system is continuously executed until both systems reach the strict synchronization point, thereby ensuring the synchronization of the entering systems.
