摘要
论文提出了一种基于多路视频服务器的字符叠加系统的方案,该系统通过AT89S52单片机控制MB90092字符叠加器进行多路视频的字符叠加;制定了一套通信协议,使本系统能够通过RS485与上位机进行通信,并实现远程用Web页面控制字符叠加内容,该方案已应用在监控系统上。
This paper provides a new plan of multi-channel OSD system based on DVS, and in this system, MB90092 OSD chip is controlled by AT89S52, thus to make multi-channel video signal display characters. Also a communication protocol is proposed, thus to let this system communicate by websever with RS485, so administrator could control the OSD with webserver on DVS.This system has been successfully used in surveillance system.
