Design of Wireless Video-on-demand System Based on ARM

基于传统VOD受到线路带宽影响导致传输速率较慢的特点,设计一种基于ARM和linux操作系统的无线视频点播系统。嵌入式平台作为视频点播终端,实现在QT界面中选择播放目录并调用mplayer播放的功能,并通过WiFi无线局域网实现播放目录的下载和视频文件的传输。PC端通过FTP服务器中的主目录实现视频文件的加载并提供资源。通过测试表明,终端上可得到实时清晰的视频画面,适合大型商场和家居环境的应用。

As traditional vod affected by the line bandwidth transmission rate of the defects,this paper designed a kind of system,which is based on ARM and Linux operating system.As the video on demand terminal,Embedded Platform selected Play List in the QT interface and called mplayer play.what＇s more,through wifi wireless Local Area Network the Embedded Platform got the directory to download and transfer video file.The PC-Port loaded and provided resources through the home directory of video files in the FTP server.According to the Test,the terminal can be obtained clear video images in real time,suitable for large shopping malls and home environment application.
