| 摘 要： | 为使图像能在Internet上传输，提出了基于VxWorks的嵌入式网络视频服务器的设计方案。方案通过SAA7113将传统的模拟视频信号转换为数字信号，由专用音视频编解码芯片AT2042对数字图像信号进行处理，在mpc860T平台上使用VxWorks实时操作系统对数据打包，经过10／100Mbps以太网接口送入Internet，从而实现图像数据的采集、压缩和在Internet上传输。

| Abstract: | In order to transmit image on the Internet, this paper gives a design scheme of embedded network video server based on Vxworks, which converts the analogue video signal to digital signal by SAA7113. The digital image signal is processed by the A/V CODEC chip AT2042, sending the compressed signal to Internet by 10/100 Fast Ethernet controller. The image capture, real time compression and online transmission thus become realizable. |
