摘　　要：随着移动多媒体在人们生活中的日益应用,移动数字电视逐渐成为人们关注的热点。本文通过描述DVB-T USB Tuner设备在基于PXA270处理器的ARM开发平台上应用的具体设计与实现方案,阐述了移动数字电视功能在ARM开发平台上实现的可行性。文章中首先介绍了如何把Linux2.6.15内核和相关文件系统移植到基于PXA270微处理器的开发板和Linux系统的启动过程,然后描述了TwinhanDTV Magic Box(VP7041)的DVB设备的驱动安装和测试过程,最后阐明通过MPEG-2TS的数据流解码实现移动数字电视播放的功能。Along with the increasingly applying of mobile multimedia in people＇s lives, Mobile digital television has gradually become the focus of attention of people. This paper describes the specific scheme of implementing the DVB-T Tuner device in an ARM platform with a PXA270 processor, and discusses the possibility of utilizing an ARM platform for digital television function. First of all, the method of porting the Linux 2.6.15 kernel to the development board with a PXA270 processor is introduced. Later on, the process of installing the TwinhanDTV Magic Box （VPT041） device driver in Linux is described. Finally, the MPEG-2 TS decoding algorithm is provided.
