本文介紹了一種基于嵌入式Linux 和S3C2410 平臺的視頻傳輸系統。該系統通過USB
攝像頭采集視頻數據，采用Video4Linux 模塊提供的編譯接口進行視頻采集程序的設計，經MPEG-4 壓縮算法對視頻流進行壓縮編碼，通過實時傳輸協議(RTP)和實時傳輸控制協議(RTCP)配合使用實現流媒體數據的網絡傳輸。整個系統建立在嵌入式構架上，能獨立完成實時視頻的采集、處理及傳輸功能，可廣泛應用于遠程監控系統、可視電話、工業控制等領域。

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 the
embedded 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.
