中文摘要：
随着嵌入式处理器运算能力不断增强，影音娱乐已经成为人们日常生活中必不可少的一部分。设计以博创公司 ARM9开发板（UP -TECH2410）为平台，以 Linux 为开发环境，Qt 为开发工具，详细介绍了硬件平台搭建，嵌入式操作系统选型，Qt Designer 以及视频播放器的设计方法。实现了 Linux 下对 LCD 的显示功能及开发板触摸屏控制的实现。通过测试，系统运行正常，性能稳定。开发过程以 ARM9与 Linux 操作系统结合开发的模式突破了以往的嵌入式开发架构，为嵌入式系统开发开辟了一种新途径。
英文摘要：
With the increasing of embedded processor capacity,the video entertainment activity has become the necessary part of people ＆#39;s life.The ARM9 development board from UP -TECH2410 BO CHUANG Company is used as the platform,Linux as the development environment,and Qt for the development tool.The construction of the hardware platform,the selection of embedded operating system, the design methods of the Qt designer and video player are introduced in detail.The function of LCD display and touch screen control are completely implemented under Linux.The results show that the system runs normally and stably.The system design mode,combining ARM9 with Linux operating system,breaks through the previous embedded development architecture and provides a new way for the embedded system development.
