视频信号低压差分转换的实现

Implementation of Video Signal to Low Voltage Difference Conversion

针对视频数据传输系统速度、距离和稳定性等要求的不断提高,设计了一种基于低压差分信号传输技术的长距离高速窜行数据传输系统设计方案,并付诸实施,从而有效解决了数据传输功耗大、稳定性差和数据传输较慢等技术问题。该系统将PAL制的模拟视频信号转换成RGB565格式的数字视频信号,然后通过DS90C383编码芯片,将16位的数据和行场信号以及使能信号转换成三路差分信号,从而实现视频信号的差分传输。

Aiming at the increasing demand of speed, distance and stability of video signal transmission system, designed and implemented the schemes about the long-distance and high-speed serial data transmission system based on the low voltage differential signal transmission technology, and solved the problems of large power consumption, poor stability and slow data transmission, etc. The system converted PAL analog video signal to RGB565 digital signal and by encoding chip DS90C383, transformed the 16 bits of data, sync signal and enable signal into three channels of differential signal, thereby realized video signal differential transmission.
