摘要 本文介绍了一种基于AT91RM9200的嵌入式网络摄像机设计方案。该系统以嵌入式Linux作为操作系统,采用MPEG-4的专用编码芯片对采集到的数字视频进行压缩编码,生成MPEG-4码流。MPEG-4码流经过AT91RM9200控制器外接的网络芯片被输送到PC机。PC机端通过内嵌MPEG-4解压插件的IE浏览器来播放视频和控制网络摄像机的状态变化。 This article introduces an embedded IP camera project based on AT91RM9200. This system uses embedded Linux as operating system, and adopts special MPEG-4 encoder chip to compress the sampling video signals, then produces MPEG-4 stream. MPEG-4 stream is sent to PC terminal through the network chip controlled by AT91RM9200. PC terminal plays live video and controls IP camera's status through IE browser embedded in MPEG-4 widget.
