摘 要: 设计并实现了一种基于嵌入式Linux和达芬奇(DaVinci)系列数字多媒体处理芯片DM355的网络摄像机。该系统利用嵌入式Linux操作系统的视频设备内核驱动(Video4Linux2, V4L2),编写驱动程序实现视频的采集,经DM355的协处理器对采集到的视频流进行MPEG-4压缩编码后,通过嵌入式Web服务器与流媒体服务器的实时传输协议(real-time transport protocol, RTP)和实时传输控制协议(real-time transport control protocol, RTCP)实现编码视频数据流的网络传输。
关 键 词: 计算机应用;网络摄像机;DM355;Video4Linux2;实时流协议

Abstract: The design and implementation of network camera are put forward based on embedded Linux and DaVinci Series digital media processor TMS320 DM355. The system uses the V4L2 (kernel driver of video device) of embedded Linux operating system to write drivers for video capture. The video streams are compressed based on MPEG-4 standard which are collected by the co�processor of DM355, and it is realized that the compressed streams are transmitted in network based on real-time transport protocol (RTP) and real-time transport control protocol (RTCP) of embedded Web server and streaming media servers.
Key words: computer application; network camera; DM355; Video4Linux2; real time streaming protocol
