Detailed Description

For the purpose of making the objects, technical solutions and advantages of exemplary embodiments of the present application more apparent, the technical solutions of exemplary embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the exemplary embodiments of the present application, and it is apparent that the described exemplary embodiments are only some embodiments of the present application, not all embodiments.

For convenience of use, various external device interfaces are usually provided on the display device, so as to connect different peripheral devices or cables to realize corresponding functions. When the high-definition camera is connected to the interface of the display device, if the hardware system of the display device does not have the hardware interface of the high-pixel camera for receiving the source code, the data received by the camera cannot be presented on the display screen of the display device.

Also, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resource, and usually only supports video decoding with a resolution of 4K at maximum, so when video chat while watching the network television is to be implemented, in order not to reduce the definition of the network video picture, it is necessary to decode the network video using the hard decoding resource (typically, GPU in the hardware system), and in this case, only the video chat picture can be processed in such a way that the video is soft decoded by a general processor (e.g. CPU) in the hardware system.

The soft decoding is adopted to process the video chat pictures, so that the data processing load of the CPU is greatly increased, and when the data processing load of the CPU is too heavy, the problems of picture blocking or unsmooth can occur. Furthermore, due to the data processing capability of the CPU, when the video chat frame is processed by adopting the soft decoding of the CPU, the multi-channel video call cannot be realized, and when the user wants to perform video chat with a plurality of other users at the same time in the same chat scene, the situation of access blocking occurs.

Based on the above-mentioned aspects, to overcome the above-mentioned drawbacks, the present application discloses a dual hardware system architecture to implement multiple video chat data (at least one local video).

The concept of the present application will be described with reference to the accompanying drawings. It should be noted that the following descriptions of the concepts are only for making the content of the present application easier to understand, and do not represent a limitation on the protection scope of the present application.

Since the functions of the operating system 3911 of the a chip and the operating system 2911 of the N chip are similar, the relevant parts only need to be referred to the operating system 2911, and the description thereof will be omitted.

A schematic configuration of an application in a display device according to an embodiment is exemplarily shown in fig. 6 b; as shown in fig. 6b, the application layer of the display device contains various applications that may be executed on the display device 200.

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

It should be noted that the multiple view display areas may present different levels of display images. For example, the first view display region may present video chat item content and the second view display region may present application layer item content (e.g., web page video, VOD presentation, application screen, etc.).

Optionally, the presentation of different view display areas has priority difference, 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 the 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 affected.

The same level of display may be presented, in which case the selector may switch between the first view display region and the second view display region, and the size and position of the second view display region may change as the size and position of the first view display region changes.

Since separate operating systems may be installed in the a chip and the N chip, there are two independent but interrelated subsystems in the display device 200. For example, android and various types of APP can be independently installed on the A chip and the N chip, so that each chip can achieve a certain function, and the A chip and the N chip can cooperatively achieve a certain function.

With the increasing attention to the user experience, the requirement on the operation performance index of the product becomes higher, and how to quickly execute and restore the factory setting and reduce the starting initialization time is a problem to be solved under the condition of meeting the function foundation. The method for quickly restoring the factory setting provided by the embodiment of the invention can shorten the time for restoring the factory setting, and when the factory setting is restored, the system does not enter the Recovery stage, so that not only can other data in the system be prevented from being completely emptied, but also the startup initialization time after the factory setting is restored can be optimized, thereby improving the user experience.

A flowchart of a method of quickly restoring factory settings is illustrated in fig. 8, according to one embodiment.

Referring to fig. 8, the method for quickly restoring factory settings provided by the embodiment of the invention is applied to an Android system, and the method comprises the following steps:

s1, acquiring a factory setting restoration instruction.

The operation of restoring the factory setting of the system is triggered by a user, and the user can execute the process of restoring the factory setting through a key control system for restoring the factory setting on the remote controller and can also execute the process of restoring the factory setting through a key control system arranged on a host computer of the system.

After the user selects the system to restore the factory setting through the factory restoring key or the local key, the system sends a command for restoring the factory setting to the system, and after receiving the command for restoring the factory setting, the system executes a corresponding process for restoring the factory setting.

S2, calling a data clearing service according to the factory setting restoration instruction, and performing data clearing operation on data needing to be cleared in the system.

And after receiving the command for restoring the factory setting, the system starts the data clearing service. The data clearing service is a novel data clearing mode provided by the embodiment, which can clear only the data which needs to be cleared in the system, and the data which is not cleared and does not affect the operation of the host and also affect the starting performance cannot be cleared.

The data to be cleaned in the system comprises pre-installed data of pre-installed application programs in the system, user data of third party application programs installed by users, cache data, data generated by WiFi communication, data generated in the Bluetooth use process and the like. And dex optimization information for preset applications of system files and vendor partition files in the system, which is stored in the data partition. If the dex optimization information is cleared when factory setting is restored, the system needs to be subjected to a startup initialization process in the restarting process, namely, the installed application is optimized again, so that the subsequent starting and running performances of the system and the application are ensured. However, the time for starting up and initializing is generally long, and generally takes 5-10 minutes according to different quantity of installed applications in the system, so that the time for restoring factory settings is too long, and the user experience is affected. Therefore, the data which is not cleared and does not influence the operation of the host and the starting performance can be cleared, and the data is not cleared when the factory setting is restored.

When the data clearing service is started to restore the factory setting of the system, a file list to be cleared, which needs to be cleared, of the system is created, wherein the file list to be cleared comprises pre-installation data of pre-installation application programs, user data and cache data of third party application programs which are installed by users, data generated by WiFi communication, data generated in the Bluetooth use process and the like. When the factory setting is restored, only the data needing to be cleared in the system is cleared, the system does not enter the Recovery stage, the data in the system can be prevented from being completely cleared, the startup initialization time after the factory setting is restored is optimized, the factory setting restoration time is shortened, and therefore user experience is improved.

When the system is in an operating state, such as that a certain application program or a certain service in the system is running, the operation of the application program is abnormal, so that the core application in the system needs to be stopped.

Specifically, after invoking the purge data service, further comprising: the operation of all services and applications in the system is stopped.

Before the data clearing operation, after the core application in the system is stopped, the efficiency of restoring the factory setting can be improved, and the time spent is shortened.

S3, restarting the system under the condition that the data clearing operation is completed, and achieving recovery of the system from factory setting.

After the data to be cleared in the system is subjected to data clearing operation, restarting the system, entering the main system, and realizing the recovery of the system from factory setting.

In the method provided by the embodiment, in the process of restoring factory settings, only one-time restarting system operation is performed after data clearing is completed, and the system is restarted back to the main system. In the factory setting restoration method provided by the prior art, two restarting operations are needed, the actual data clearing operation is performed when one restarting enters the Recovery mode, and the main system is returned after one restarting. Compared with the prior art, the method provided by the embodiment reduces the consumption of one-time restarting, shortens the time for clearing the data and does not need the startup initialization process, further shortens the time for restoring the factory setting, improves the efficiency for restoring the factory setting, and has good user experience.

As an optional embodiment, in the method provided in this embodiment, when factory setting is restored to the system, a clear data service is adopted to screen data types in the system, and clear data operation is performed only on data that is needed in the system and can be cleared, for this purpose, according to a factory setting restoration instruction, the clear data service is called to perform a process of clear data operation on data that needs to be cleared in the system, and fig. 9 is an exemplary flowchart showing a method for calling the clear data service according to an embodiment; as shown in fig. 9, includes:

s21, acquiring a file list to be cleaned, which is required to be cleaned of data, in the system according to the factory setting restoration instruction.

After receiving a factory setting restoration instruction triggered by a user, the system sorts the data of each service in the system, the user data and the cache data of each application program, and determines that a file list needs to be cleared.

S22, traversing the files to be deleted in the file list to be deleted, and judging whether the files to be deleted are white list files or not.

The data in the file list to be cleaned are files to be deleted, and the files to be deleted comprise the data to be cleaned and the data which can influence the starting performance and can not be cleaned and can not influence the operation of the system. Therefore, in determining which data in the file list to be cleared is available and which data is not cleared, the embodiment makes a determination through the white list file.

The white list file comprises data which can influence the starting performance and the operation of the whole machine when the white list file is not cleared.

In particular, a flow chart of a method of determining a whitelist file according to an embodiment is exemplarily shown in fig. 10; as shown in fig. 10, the present embodiment determines a white list file according to the following steps:

S221, acquiring all service types and all application program types in the system.

Each service in the system generates data during use, and each third party application program installed by each user generates data, such as user data and cache data, during use.

Each service type can generate different service data according to different provided functions, each third party application program can also generate different application program data, and whether each data in the system needs to be cleared or not can be judged according to the service data and the application program data.

S222, judging whether the service data corresponding to each service type can be subjected to data cleaning or not, and judging whether the application data corresponding to each application type can be subjected to data cleaning or not.

And respectively judging whether the data clearing operation can be performed on the determined different service data and application program data, wherein the judging basis is whether the data can influence the starting initialization process if being cleared and whether the running state of the system can be influenced if not being cleared.

S223, if the service data needs to be cleared and the application program data cannot be cleared, a white list file is established according to each service data and each application program data which cannot be cleared.

After the different service data and application program data are judged, if a certain service data or application program data is cleared, the starting initialization process is affected and is not cleared, the data does not affect the running state of the system, and then the data meeting the condition is determined as the non-cleared data.

And establishing a white list file according to all the non-cleanable data determined according to the judging conditions. The white list file can accurately determine which data in the system can be cleared and which data cannot be cleared, so that the efficiency of restoring factory settings is improved.

S23, if the file to be deleted is not the white list file, the data clearing operation is carried out on the file to be deleted.

Traversing a file list to be deleted, if a certain file to be deleted is matched with a certain file in the white list file, the file to be deleted is non-cleanable data, and the data cleanup operation is not executed on the file to be deleted. If the file to be deleted is not matched with any one of the white list files, determining that the file to be deleted is data which can be cleared, and carrying out data clearing operation on the file to be deleted.

Therefore, in the method provided by the embodiment, after receiving the command for restoring the factory setting, the system immediately acquires the file list to be cleared, which needs to clear the data, in the system. When the factory setting is restored, only the files to be deleted, which do not belong to the white list files, in the file list to be deleted are subjected to data clearing operation, so that the influence on the starting initialization process after data clearing is avoided, the time for restoring the factory setting can be shortened, and the efficiency for restoring the factory setting is improved.

Typically, the system can provide multiple functions, and can also install multiple third party applications on its own, resulting in a large amount of data in the system. When the factory setting is restored by adopting the method provided by the embodiment, a large number of files to be deleted need to be removed from the file list, and if the large number of files to be deleted are compared with the white list file, confusion is easy to occur, so that accurate data needing to be removed cannot be performed.

Therefore, according to the method provided by the embodiment, the data in the system are partitioned, the data in each partition are judged in sequence, and after the judgment of one partition is completed, the data of the next partition is judged, so that the judgment of the data in all the partitions in the system is completed more orderly, and the accuracy of determining the data to be cleared is ensured.

In particular, a method flow diagram for invoking a purge data service in accordance with another embodiment is illustrated in FIG. 11; as shown in fig. 11, before determining whether the file to be deleted is a white list file, the method further includes:

S31, traversing the files to be deleted in the file list to be deleted, and judging whether the files to be deleted are partition files corresponding to the current partition.

The large amount of data existing in the system belongs to different file types, so that each data can be divided into a plurality of partitions according to the file types, for example, data (data) partitions, cache (cache) partitions and the like.

And each partition comprises a large amount of data, and the data is used as a partition file to be used as a basis for judging that the file currently judged belongs to the corresponding partition.

In the method provided by the embodiment, when the judging process of the current partition is performed, the file list to be cleaned needs to be traversed, and whether the attached file to be deleted is the partition file corresponding to the current partition is sequentially judged.

The current partition refers to a partition where data is located when the system is recovering from factory setting, and whether the partition is the partition where the data need to be cleared is judged.

S32, if the file to be deleted is the partition file of the current partition, executing the step of judging whether the file to be deleted is a white list file.

When judging whether each file to be deleted in the file list to be deleted belongs to the current partition in sequence, if the file to be deleted which is judged currently does not belong to the current partition, the step of judging whether the file to be deleted is a white list file is not executed, and the next file to be deleted is continuously judged; if the file to be deleted currently judged is matched with the partition file of the current partition, the step of judging whether the file to be deleted is a white list file or not is continuously executed on the file to be deleted, namely, the steps from S22 to S23 are executed.

For example, taking a data partition as an example, if a file to be deleted in the list file is a partition file of the data partition, continuing to execute the step of judging whether the file to be deleted is a white list file, and if the file to be deleted is not the white list file, executing the data deleting operation on the file to be deleted. If a certain file to be deleted in the list file is not the partition file of the data partition, discarding the file to be deleted, and continuing to judge whether the next file to be deleted is the partition file of the data partition.

Therefore, according to the method provided by the embodiment, by sequentially judging whether each file to be deleted in each partition belongs to the current partition, when the file to be deleted belongs to the current partition, the step of judging whether the file to be deleted is a white list file is executed, so that whether all files to be deleted in the file list to be deleted are white list files can be orderly determined, confusion in the judging process is avoided, data clearing efficiency is improved, and the time for restoring factory settings is shortened.

When executing the data clearing operation on all the data in the system in the partition mode, the method provided by the embodiment adopts the data clearing operation on the data needing to be cleared in one partition, and then executes the data clearing operation on the data needing to be cleared in the next partition, so that confusion is avoided, and the data clearing efficiency is influenced. Only after all the partitions in the system are cleared, the system is re-used to enter the main system, and factory setting recovery is completed.

Specifically, a method flow diagram for restarting a system according to an embodiment is exemplarily shown in fig. 12; a method flow diagram for performing a data purge operation on partitions in a system according to an embodiment is illustrated in FIG. 13; as shown in fig. 12 and 13, in the method provided in this embodiment, a process of restarting a system includes:

S41, after the data of the current partition is subjected to data clearing operation, the partition file of the next partition is subjected to data clearing operation.

Taking the data partition and the cache partition in the system as an example, after all files to be deleted in the data partition are removed, the data removal operation on the files to be deleted in the cache partition is executed, so that the system can orderly remove the data, confusion is avoided, and the data removal efficiency is ensured.

Specifically, when the data partition is cleared, whether the current file to be deleted in the list file to be cleared is the partition file of the data partition is judged first, if so, the step of judging whether the file to be deleted is a white list file is continuously executed, and if not, the data clearing operation is executed for the file to be deleted. If the current file to be deleted in the list file is not the partition file of the data partition, discarding the file to be deleted, and continuing to judge whether the next file to be deleted is the partition file of the data partition.

After the data clearing operation of all the files to be deleted in the data partition is completed, the data clearing operation is carried out on the files to be deleted of the cache partition. Firstly judging whether the current file to be deleted in the list file to be deleted is a partition file of a cache partition, if so, continuing to execute the step of judging whether the file to be deleted is a white list file, and if not, executing the data deleting operation on the file to be deleted. If the current file to be deleted in the list file is not the partition file of the cache partition, discarding the file to be deleted, and continuing to judge whether the next file to be deleted is the partition file of the cache partition.

And if the files to be deleted of the cache partition are all subjected to data clearing operation, carrying out the data clearing operation process of the next partition until all the partitions in the system are subjected to data clearing operation.

S42, if all the partitions in the system complete the data clearing operation, synchronizing the data clearing result of each partition in the system.

After all partitions in the system complete the data clearing operation, the data clearing operation of each partition needs to be synchronized to accurately determine the time point of restarting the system, so that the condition that a certain partition in the system is carrying out the data clearing operation and the system is restarted to cause the process of restoring the factory settings to be abnormal is avoided.

S43, restarting the system under the condition that the synchronous operation is completed.

After the synchronous operation is finished on the system, the system can be restarted, and the factory setting recovery process is finished.

According to the technical scheme, the method for quickly restoring the factory setting comprises the steps of calling the data clearing service according to the instruction for restoring the factory setting, carrying out data clearing operation on data to be cleared in the system, restarting the system under the condition that the data clearing operation is completed, and achieving restoration of the factory setting of the system. Compared with the prior art, the method provided by the embodiment reduces the consumption of one-time restarting, is simple to operate, and the system does not enter the Recovery stage, so that the data in the system can be prevented from being completely emptied, the starting initialization time after factory setting Recovery is optimized, the factory setting Recovery time is shortened, and the user experience is improved.
