Converters.TV Digital Line Doubler is a device that takes both NTSC and PAL video inputs, doubles their horizontal frequency to 31 KHz, and outputs as an analog RGB signal in VGA format. It can be used as an interference unit between composite video sources and high-resolution large-screen TVs.
The Digital Line Doubler eliminates the flickering associated with most composite video sources and enhances the picture quality by doubling their horizontal resolution.
It has four separate video inputs (2 (Video or S-Video), 1 CGA, 1 VGA) that can be converted into high-resolution RGB output with no flickering.
