Abstract
Description
technical field
[0001] The invention relates to the field of digital media technology and digital TV communication, and mainly refers to a method for presenting information on a digital TV receiver. Background technique
[0002] At present, the process of presenting information such as text, graphics, images, and sounds (including advertisements, icons, subtitles, symbols, etc.) on a digital TV receiver is to generate a basic operation interface through a GUI (graphical user interface) written in C / C++ language Control flow and present information. Common such as application program interface (including control and display). The process of presenting information is to write special software on the receiver and solidify it in the receiver. These special software can analyze the audio, video and business information on the digital video broadcasting network through user operations and input parameters. Through C / C++ program code present this information.

Embodiment Construction
[0021] The present invention will be further described below in conjunction with accompanying drawing:
[0022] The principle of animation technology is to use ECMA script (script rules promulgated by the ECMA organization), ActionScript to describe the behavior of objects, and AVM (Action Script Visual Machine for short) to explain and execute the presentation information, using XML language (Extensible Markup Language). A way of presenting information for message communication. The design principle of the present invention is to replace the GUI layer of the digital television receiver software with the application layer where the animation player and user application program are located, and an adaptation layer is added between the original GUI layer and the system. The operation instruction is transformed into graphics operation, and the system data operation and system task management interface realizes external data exchange, as shown in Figure 1. The animation applicati...
