Homemade Composite Video Quad Processor Help

[Jbax1899]

Hello,

For a project I am working on I need to somehow convert a single Composite Video (from RCA cable) to four Composite Video outputs, each a quadrant of the output. It is a bit hard to explain at times, so I attached a sketch.

My idea is this: With a raspberry pi or something similar I can build a "calculator" that runs numbers and spits out a quarter of the input across four outputs, so that I can essentially hook up four monitors to that one input. If there are devices that would do this for me, they are too expensive. Trust me I've looked. VGA and HDMI ones cost a fortune and are way to bulky for my project, and ones for RCA are even less in demand.

 

Anyway, is this feasible at a low cost? Is it feasible at all?

Nope, if you knew what you are doing you could reverse engineer the a fpga or something, but it won't be easy. The best and easiest way is to get a computer with multiple video outputs and use something like nvidia mosaic or amd eyefinity.
