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

Considering that there is no valid data in the vertical blanking intervals of the video signal, bulk transfer with one field as a unit is used in the input channel.
针对视频图像场消隐期间无有效数据的特点，输入通道中外设以场为单位分块传输实时泄漏截获数据至主机。

The signalblanking procedure is an effective measure to enhance the RF signal compatibility of all synthetical electronic systems.
