Seeking Video Generator IC

I am looking for a device which will generate video from attached memory
containing bitmaps. I would like to be able to generate NTSC,PAL,RS343 and
RS170 video from bitmaps I can change in Flash or SRAM.So hopefully the
device will contain memory addressing and timing parameter registers.
Considering building our own logic to do this but I have to assume there are
solutions on the shelf somewhere.


 If anyone has experience with these device or can point me in any direction
I would appreciate it. Perhaps another newsgroup?

Thanks

a bit more stuff here
http://www.astro.uu.se/~marcus/private/newvidproc.html
and some "jungle" IC's here
http://www.search.philips.com/search/search?q=saa71+video&s=semi&l=global&h=semi
and genlock chips

If you find any dual port video ram thats easily avalable, please let
me know

Fujitsu makes a series of graphic controllers that might be suitable.
Look at

You didn't say what sort of resolution or bit depth you were looking
for.

If you only need low res monochrome, there are many options including
the SV1000 and SV2000 from speechchips.com

hmmm.. NTSC is 720x480. RS343 is ~810x1080.
