摘　　要：DVI接口(Digital Visual Interface)标准作为新一代的数字显示技术通讯标准[1],以全数字化的数据码流在传输信道上传输,文章通过对DVI接口应用系统的研究,提出了一个数字视频传输到数字显示的解决方案。通过分析与DVI应用相关的DDC(Display Data Channel)和EDID(Extended Display Identification Data)的设计方法,介绍了数字视频接口DVI系统的基本结构和原理,该接口系统应用在16x32像素全彩色LED显示屏系统上,能够很好地解码计算机输出的数据流,R、G、B数据可以正确地传输到LED屏显示系统并实时显示,经测试系统能稳定运行。The standard of DVI interface as a new generation digital display technology communication standard,transmission in the channel as fully digital code stream. This paper proposed a digital video transmission to digital display solutions based on the research of the DVI interface application system. By analyzing the DVI application design methods related DDC and EDID, this paper introduces a digital video interface system of DVI basic structure and principles;this interface system apply in 16 x32 pixels full color LED display system, can decode data stream of computer, RGB data can be correctly transmitted to LED and displaying real-time. After the test, system runs stably.
