Chips which decode NTSC-encoded color video into RGB and sync are available
from a number of sources; check out a recent Motorola "Linear and Interface
ICs" databook for several.  However, you're likely to run into a problem with
timing - standard NTSC video is a 15.734 kHz-horizontal, interlaced format,
and nearly all monitors intended for computer use - including those in the
PS/2 line - are intended for considerably higher rates.  Thus, even if you
get the RGB and sync signals sorted out, the monitor still won't like 'em.
(Yes, there are ways to put NTSC video on a computer display - but they're
not easy/cheap, at least compared to what I think you want here.)
