摘要
本文通过对DVI通信协议,TMDS的链路构成、信号特性、编码及解码算法分析。提出针对数字电视中的实际应用方案,简化了数字→模拟→数字繁琐的转换过程,解决了模拟传输环节中难以抑制的噪声干扰问题,有效避免了信号的损失和受到的干扰。有效消除拖影现象,使图像的清晰度和细节表现力都得到了大大提高,电视画面色彩更纯净,更逼真。
This paper discusses the applications of digital visual interface technique, including DVI communication protocols, the setting up of TMDS active digital visual link, signal characteristics, signal encoding, transmitting and decoding, and also introduces the requirement and notes in PCB layout of digital visual differential trace on the basis of implementation .
