摘要
为使图像能在In ternet上传输,提出了基于V xW orks的嵌入式网络视频服务器的设计方案。方案通过SAA 7113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AT 2042对数字图像信号进行处理,在m pc860T平台上使用V xW orks实时操作系统对数据打包,经过10/100M bps以太网接口送入In ternet,从而实现图像数据的采集、压缩和在In ternet上传输。
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.
