摘　　要：基于ARM9架构的微控制器S3C2440以及Linux操作系统成功实现数字视频传输。通过采用V4L2提供的接口函数,实现数据的采集。V4L2是linux2.6内核所具有的视频设备驱动规范。采集到的视频信息可以利用TCP/IP协议传输,局域网内的用户可实时地获得视频图像,从而实现实时视频监控。实验结果表明:系统性能稳定、实时性好,具有广泛的应用价值。Realtime digital video transmission is successfully implemented based on ARM9-based microcontroller S3C2440 and embedded Linux operating system. It captures the video data by using V4L2 ,encodes the video by u- sing the encoding modules which is integrated in S3C2440. V4L2 is the API（ Application Program Interface） of video capture device driver video data can be translated by TCP / IP protocol remote real-time monitoring video can be displayed to users. The experimental result shows that the system has high practical value, and this system can be widely used in many occasions.
