Lots of (9 or 16) scan converters, actually it's probably not that hard
to do - doesn't need much total RAM (maximum 1Mb for a 24-bit NTSC image - they
probably use 8-16 bits, and probably get to waste a lot because they need
to partition the RAM over the 9/16 scan converters).

You could probably put it all together for under $10k (retail in volume)
