Looking for info on driving video signals

Hello all. I'm looking to build a circuit capable of driving most
NTSC input compatible devices, but having a hard time finding out what
exactly that requires. I found good info on the RS-170 standard, NTSC
voltage levels, and the like, but very little about what kind of
current/power draw I should expect from a "typical" receiver ala VCR/
TV set/LCD monitor. Anyone have any experience with this? In basic
terms I'll have a couple of video signals coming from various cameras
(all NTSC standard outputs) that will go through video multiplexors
(probably the LMH6574 from National Semiconductors) and likely finish
it off with a nice amplifier/driver to give it enough oomph for
transmission through a TBD cable to a TBD monitor. The cable will
likely be 75 Ohm impedance (might use a standard RCA style for
testing). Oh yeah, and it'd be great if there was a nice way to
protect it from ESD damage too... So what does the amplifier/driver
need to be able to handle? Any companies/lines to avoid or prefer?
Easily avaiable is a plus (Digikey is our friend), price not a big
issue so long as it works well.
Thanks for any advice!
