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。关键词：S3C2410；嵌入式系统；MPEG-4；流媒体Design of transmission system of video image based on the embedded System Zhang Suwen Fu Wei Liu Minglan (College of Automation ,WuHan University of Technology ,WuHan,430070) Abstract: 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 collection programme of video image. The video image be compressed by the compress arithmetic of MPEG-4. The stream medium be ransmitted by using the RTP and PTCP protocol together. The whole system based on theembedded system. It can independently complete the function of the collection, processing and transmission of the real-time video. In can be widely used in the field of long-distance monitor system, video telephone, industry control and so on.Keywords: S3C2410 ; embedded system; MPEG-4; stream medium
