Digital frames in RAM to Analog output, Please help ! Options

Hi all !
I have a memory buffer/array in my application (Builder C++ 4.0)
which represents frames of video, every 20 miliseconds I'm
refreshing the data in the buffer. I need somehow, to make this
digital frames, to come out as an Analog signals out of my PC,
I need to send it to another computer (as an analog data) for
example by using BNC cable, or just to send it directly into a
small black and white CRT screen, to see the frames as a
Black/White video.
My buffer use 8 bits for each pixel, and the buffer size is 320
x 240 pixels.
I have no Idea how to do that !
Is there any ready driver/application that I can use? Is it
possible to send this frames as an analog output through
the "TV-Out" output of my PC graphics card? (for example
Geforce card)
Please give any information you can, I really need to find a solution
very soon.
Thanks very much!
Best Regards,
Tom.

Hi Tomi,
These are mere ideas...
Definitely look at using DirectX as it
has procedures for writing image data
from main memory to you gfx cards ram.
I haven't done this myself but I read
a lot about it... Perhaps someone here
can tell you more...
I think what you want to do it quite
doable if you can find out enough about
your hardware...
HTH,
