大型运动会无线资讯系统

Wireless Information System for Large Sports Games

在大型运动会中为了使观众在现场观看比赛时能够获得全方位的资讯,开发了一种基于ARM嵌入式系统设计的无线多媒体资讯系统,介绍了终端系统音视频处理、资料的无线传输以及PC上位机应用层资料处理等各功能模块的工作原理,并分别从硬件结构、软件流程两个主要环节对系统实现过程进行说明,系统具有很好的应用前景。

In order to provide spectators with information of full orientation in large sports games, a wireless multimedia information based on ARM embedded system is developed. The principles of each functional module, e.g. video/audio processing of terminal system, the wireless transmission of information, and the information processing on application layer in PC server, are introduced. The system implementing procedure is discussed from the two main aspects of hardware structure and software procedure. The system offers an prospective future in application.
