Introduction
This unit is a digital line doubler which is designed to take both NTSC and PAL video
inputs, double scan their horizontal frequency to 31 KHz, and output as analog RGB
signal in VGA format. It is used as an interference unit between composite video sources
and high-resolution large screen TV. The unit will eliminate the flickering associated
with most composite video sources and enhance the picture quality by doubling their
horizontal resolution.
