Application of MPlayer and Qtopia in Embedded Wireless Karaoke Demand Terminal

主要介绍MPlayer和Qtopia在嵌入式无线卡拉OK点播终端中的应用:首先分析了MPlayer的体系结构,并在此基础上给出了将MPlayer移植到三星ARM9嵌入式平台的详细过程。介绍了在宿主机建立Qtopia和Qt/Embedded交叉编译环境的过程,并基于Qtopia和Qt/Embedded体系结构,设计了嵌入式无线卡拉OK点播终端的交互式用户界面。

This paper mainly introduces the Application of MPlayer and Qtopia in Embedded Wireless Karaoke Demand Terminal. Fist, the author analyses the architecture of MPlayer, on the basis of that the author introduces the process of the transplantation of MPlayer to Samsung ARM9 embedded platform in detail. Then the author introduces the process of the establishment of cross - compilation environment for Qtopia and Qt/Embedded on the host computer. Basing on the architecture of Qtopia and Qt/Embedded, the author designs a friendly man -machine interface according to the needs of the Karaok demand terminal.
