Widget middleware system based on smart television

Abstract

The invention discloses a widget middleware system based on a smart television. The widget middleware system based on the smart television comprises a widget middleware, a widget application layer and an operation system. The widget middleware comprises a three-dimensional figure engine, an extensive makeup language (XML) parsing engine, an information engine, a network transmission engine and a file operation interface, wherein the three-dimensional figure engine is used for displaying of figures and interfaces, the XML parsing engine is used for parsing XML files, the information engine is used for coordinating information process of communication between a task and a progress, the network transmission engine is used for supporting a file transfer protocol and building a network connection to achieve information transmission, and the file operation interface is used for supplying a programmatic interface for a widget application program to carry out file operation. The widget application layer comprises a main control module and a download module. According to the widget middleware system, a widget technology is adopted to structure a widget application on the smart television, the advantages of being flexible, light, convenient, small in occupied system resource, standard in interface and the like of widget can be expressed, common-used functions such as figure display, XML parsing and network transmission are integrated on the widget middleware, and the widget middleware system facilitates application and development of the application layer.

Description

Technical field [0001] The invention relates to the field of smart TVs, in particular to a widget middleware system based on smart TVs. Background technique [0002] Smart TV is a new TV product with a fully open platform and an operating system. While enjoying ordinary TV content, customers can install and uninstall various application software by themselves, and continue to expand and upgrade their functions. Smart TVs can continue to provide customers with a rich and personalized experience. Currently, desktop applications on embedded systems such as smart TVs are becoming more and more abundant, and their display effects are becoming more and more in line with user habits. As the hardware architecture of smart TVs still adopts embedded architecture, resources are still relatively scarce, and engineers are required to develop programs using resources rigorously and economically. [0003] Widget is a component technology that is gaining more and more recognition. It is characte...
