嵌入式視頻圖像傳輸系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)

本文介紹了一種基于嵌入式Linux 和S3C2410 平臺(tái)的視頻傳輸系統(tǒng)。該系統(tǒng)通過USB
攝像頭采集視頻數(shù)據(jù)，采用Video4Linux 模塊提供的編譯接口進(jìn)行視頻采集程序的設(shè)計(jì)，經(jīng)MPEG-4 壓縮算法對(duì)視頻流進(jìn)行壓縮編碼，通過實(shí)時(shí)傳輸協(xié)議(RTP)和實(shí)時(shí)傳輸控制協(xié)議(RTCP)配合使用實(shí)現(xiàn)流媒體數(shù)據(jù)的網(wǎng)絡(luò)傳輸。整個(gè)系統(tǒng)建立在嵌入式構(gòu)架上，能獨(dú)立完成實(shí)時(shí)視頻的采集、處理及傳輸功能，可廣泛應(yīng)用于遠(yuǎn)程監(jiān)控系統(tǒng)、可視電話、工業(yè)控制等領(lǐng)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.
