在行场消隐期间传送行场同步信号，使收、发的扫描同步，以准确地重现原始图像。

In the field blanking period of transmission line field synchronizing signal, so that the charge, the synchronous scanning, to accurately reproduce the original image.

其中的视频同步信号生成电路以及视频图像数据地址生成电路采用了PLD器件，这样就可以很方便地去改变视频制式，也便于调试。

PLD is used to produce the video synchronization signal and the logical address of the video image. So it is very convenient to change the forms of the video and easy to debug!

利用该视频同步信号发生器控制非标准图像采集卡实现了计算机辐射的随机视频信号的采集和稳定显示。

Using this generator of video synchronous signals to control an image capture card, the acquisition and steady display of the stochastic video information radiated from computer were achieved.
