Hi folks,
I've looked hi and low (I've worn out my keyboard's G, O, L, E keys)
and can't seem to find anybody who still manufacturers an On Screen
Display chip that works with composite video. NEC claims to make a
couple (uPD6464A and uPD6465) but where the heck can one get small
quanities?
I'm not really interested in a solution that is also a microcontroller
with built-in OSD. Those tend to be pretty expensive (and also hard to
get samples of) or masked parts (which means you need to buy a whole
lot of them). And I've seen some pretty slick OSD implementations done
using PICs and AVRs to do the genlock and video generation, but I'm
not sure I'll be able to clean that up enough to meet NTSC standards.
I'm just trying to design a simple board that will plug between a
composite video color camera and a monitor or VCR and display some
information on the screen. Volume might be a few hundred to a thousand
a year. I'd really like to use a chip currently in production, not
something like the STV5730.
Thanks for your help,
Mark Hahn
