摘要
介绍一种基于ATMEL公司ARM9微处理器AT91RM9200的嵌入式多路视频监控系统方案。系统以嵌入式Linux操作系统为平台,采用TECHWELL公司的TW2834芯片对4路视频进行A/D转换,然后通过IMTIME公司MPEG-4的专用编码芯片IME6500对采集到的多路视频信号进行压缩编码,生成MPEG-4视频流。
In this paper, an embedded multi-path video monitoring system based on ARM9 microprocessor AT91RM9200 of company ATMEL is introduced, This system adopts the embedded Linux operation system, and does the A/D conversion of 4 video streams by using the chip TW2834 of company TECHWELL, and also compresses and codes the adopted multi-path video signals by using the MPEG-4 special coding chip IME6500 of company IMTIME. And thus, the MPEG-4 video stream is generated.
