Extensible Linux smart television operating system easy to upgrade

Abstract

The invention provides an extensible Linux smart television operating system easy to upgrade. The extensible Linux smart television operating system easy to upgrade comprises a UI, a main program, a plug-in set, a platform abstraction layer library and a basic platform function library. The main program traverses a module plug-in directory in the plug-in set, all module plug-ins contained in the module plug-in directory are loaded one by one in a dynamic loading mode, the main program informs a UI of all supported module plug-ins after traversing is completed, and after the UI receives an announcement of the main program, a corresponding UI interface is displayed according to the currently supported module plug-ins; each plug-in module calls a basic platform function library through a platform abstraction layer library to realize calling of a function interface; the coupling of codes of each layer of software is reduced, so software compiling and running are more flexible and convenient.

Description

technical field [0001] The invention relates to an easily upgradeable and expandable Linux smart TV operating system. Background technique [0002] Existing TV systems include at least multiple functional modules, such as network modules, Bluetooth modules, TV channel search modules, smart APP function modules, etc. A TV manufacturer often produces multiple types of TVs. A smart TV includes a smart APP function module, and another non-smart TV does not include a smart APP function module; another example: a TV manufacturer may produce a high-end brand product that includes a Bluetooth module, and another low-end brand product does not include a Bluetooth module. bluetooth module. These brands and models may have most of the same functional modules, but there are differences in individual functional modules. If the codes of each brand model are written separately, there will be a lot of repetitive writing work. In addition, if a module finds a BUG, ​​then it is necessary to...

AI Technical Summary

Problems solved by technology

[0004] 1. All modules are integrated in one software. If one module is changed, all modules need to be compiled, which takes a long time to compile;

[0005] 2. If all functional modules are compiled into a TV system, the upgrade requires the entire software to be upgraded together, including the modules that have not been updated. The upgrade file is large, and the upgrade takes a long time. There will be problems with unsuccessful upgrades;

[0006] 3. The module cannot be disassembled, and the software needs to be recompiled if the module is removed or added
