摘要
分析了传统视频墙显示系统的应用现状,针对目前视频墙系统存在的传输距离短以及信源位置固化等问题,提出了一种基于多媒体通信的数字视频墙解决方案,并研究了视频图形阵列(VGA)编解码、同步传输和拼接控制等关键技术,最后给出了该方案具体实现方法和处理流程。
The status of a traditional large screen system in command center is analyzed. Aimed at problems of short transmission distance and fixed sources, a digital screen display system based on multimedia communication is proposed. Key technologies of video graphics array (VGA) encode and decode, transmission synchronization and image joint control are studied. The realizing method and the process flow are given.
