As shown in fig. 4, the system of the display device is divided into three layers, i.e., an application layer, a middleware layer and a hardware layer from top to bottom.
The Application layer mainly includes common applications on the television and an Application Framework (Application Framework), wherein the common applications are mainly applications developed based on the Browser, such as: HTML5 APPs; and Native APPs (Native APPs);
an Application Framework (Application Framework) is a complete program model, and has all basic functions required by standard Application software, such as: file access, data exchange, and interfaces to use these functions (toolbars, status lists, menus, dialog boxes).

At present, the background service and the application of the intelligent display equipment based on Linux basically carry out pre-linking operation, so that the quick loading of the service/application of the display equipment is realized, and the starting speed of the display equipment/application is improved. The pre-linking operation is usually executed after the software is compiled, and then the software with the pre-linking information is packaged to generate a whole display equipment software upgrading package. Therefore, the upgraded software of the display equipment can be guaranteed to have the starting speed improving effect brought by the pre-linking every time. However, there is a need for individual upgrades of applications in display devices: only a certain application is updated and the display device is not upgraded as a whole. The traditional pre-linking based on the whole software cannot achieve the original effect. The update of the application may cause the shared library in the display device system to change, resulting in the failure of the pre-link and even affecting other programs in the system.
In order to solve the above technical problem, an embodiment of the present application provides an application upgrading method, as shown in fig. 5, the method includes:
the server is configured to perform step S501: executing a pre-linking operation on the basic service and the basic shared library and reserving pre-linking cache information;
in some embodiments, programs in a display device system can be broadly classified into two categories by their function: basic services of the display device and applications of the display device.
The basic service of the display device is responsible for managing basic functions of the display device, such as managing network connections, receiving remote control signals, managing sound and image output, and the like.
Applications of the display device include applications other than basic services of a conventional basic display device, such as Netflix, YouTube, and the like.
Whether an application or a service program, often depends on some shared libraries themselves, and in some embodiments, shared libraries on which multiple services/applications depend simultaneously are referred to as common shared libraries, and shared libraries on which only a single program depends are referred to as proprietary shared libraries. The shared libraries depended on by the public shared library and the basic service are used as basic shared libraries to be distinguished from the exclusive shared libraries depended on by the application. As shown in fig. 6, the proprietary shared library 1, the proprietary shared library 2, and the proprietary shared library 3 only have a single service/application dependency, and the base service 1, the base service 2, the application 1, and the application 2 all depend on a common shared library. The private shared library 1, the private shared library 2 and the public shared library form the basic shared library.
In some embodiments, the pre-link cache information includes a correspondence between a shared library and a memory address.
The server is configured to perform step S502: and packaging the basic service and the basic shared library which have executed the pre-link operation and the pre-link cache information to generate a whole software package.
The controller is configured to perform step S503: downloading complete machine software package from server
The controller is configured to perform step S504: and installing the whole software package.
After the whole software package is installed on the display device, the display device system will have the pre-link cache information of the basic service and the basic shared library.
The server is configured to perform step S505: and generating an application upgrading package.
When a single new application is upgradeable in a server, there will be an application upgrade package in the server. When a single application is upgraded, only the application itself or the library on which the application depends can be updated, other parts in the system cannot be changed, and only the application which is actually updated is failed in the pre-link function.
The controller is configured to perform step S506: the application upgrade package is downloaded from the server,
the controller is configured to perform step S507: and installing an application upgrading package.
In some embodiments, the application upgrade package includes an upgrade application and/or a shared library on which the upgrade application depends;
the controller is configured to perform step S508: performing a pre-linking operation on the upgraded application and/or the shared library on which the upgraded application depends based on the pre-link cache information.
In some embodiments, like the application 1 in fig. 6, when the application 1 is upgraded, the application upgrade package of the application 1 only includes the upgraded application, and then only the pre-linking operation is performed on the upgraded application based on the pre-link cache information. Like the application 2 in fig. 6, when the application 2 is upgraded, if the application upgrade package of the application 2 only includes the exclusive shared library 2, only the pre-linking operation is performed on the exclusive shared library 2 based on the pre-link cache information. If the upgrade application and the exclusive shared library 2 are included in the application upgrade package, a pre-linking operation is performed on the upgrade application and the exclusive shared library 2 based on the pre-link cache information.
An embodiment of the present application provides another application upgrading method, as shown in fig. 7, the method includes:
the server is configured to perform step S701: executing a pre-linking operation on the basic service and the basic shared library and reserving pre-linking cache information;
the server is configured to perform step S702: performing pre-linking operation on the built-in application and/or a shared library corresponding to the built-in application based on the pre-linking cache information;
the built-in application generally refers to an application carried by a display device during production and delivery, and does not need to be downloaded and installed by a user.
The server is configured to perform step S703: and packaging the basic service and the basic shared library which are subjected to the pre-link operation, the built-in application and/or the shared library corresponding to the built-in application, and the pre-link cache information to generate a whole software package.
The controller is configured to perform step S704: and downloading the whole software package from the server.
The controller is configured to perform step S705: and installing the whole software package.
After the whole software package is installed on the display device, the display device system will have the pre-link cache information of the basic service and the basic shared library.
The server is configured to perform step S706: and generating an application upgrading package.
When a new application is upgradeable in the server, there will be an application upgrade package in the server.
The controller is configured to perform step S707: and downloading the application upgrading package from the server.
The controller is configured to perform step S708: and installing an application upgrading package.
In some embodiments, the application upgrade package includes an upgrade application and/or a shared library on which the upgrade application depends;
the controller is configured to perform step S709: performing a pre-linking operation on the upgraded application and/or the shared library on which the upgraded application depends based on the pre-link cache information.
The result of the whole software pre-linking is that for each software version, the application program and the shared library are strongly dependent, wherein the change of any shared library can cause the pre-linking of the application depending on the shared library to fail. I.e., if the application in the different version of the software package is to be validated, the shared library is not mixable. However, there is a need for individual upgrades of applications in display devices: only certain applications are updated and the television is not upgraded as a whole. The traditional pre-linking based on the whole software cannot achieve the original effect. The update of the application may cause the shared library in the television system to change, resulting in the failure of the pre-link and even affecting other programs in the system.
In order to solve the above technical problem, an embodiment of the present application provides another application upgrading method, as shown in fig. 8, where the method includes:
the server is configured to perform step S801: storing a basic shared library of each complete machine software version, which is executed with a pre-linking operation;
