摘　　要：本文介绍了一种基于嵌入式Linux和S3C2410平台的视频传输系统。该系统通过USB摄像头采集视频数据,采用Video4Linux模块提供的编译接口进行视频采集程序的设计,经MPEG-4压缩算法对视频流进行压缩编码,通过实时传输协议(RTP)和实时传输控制协议(RTCP)配合使用实现流媒体数据的网络传输。整个系统建立在嵌入式构架上,能独立完成实时视频的采集、处理及传输功能,可广泛应用于远程监控系统、可视电话、工业控制等领域。The paper introduce a video image system based on the embedded Linux and S3C2410. The system catch the video image through the USB camera. The design use the translate and edit interface providing by Video4Linux module to design the eolleetion programme of video image. The video image be compressed by the compress arithmetic of MPEG-4. The stream medium be transmitted by using the RTP and PTCP protocol together. The whole system based on the embedded system. It can independently complete the function of the collection, processing and transmission of the real-time video. In ean be widely used in the field of long-distanee monitor system, video telephone, industry control and so on.
