Hi all !
I have a memory buffer/array in my application (Builder C++) 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.

Can you draw your buffer on the PC screen?
If you plug the PC into a TV, can you show the screen on the TV?
Could you send the digital data to the other computer and convert it
to analog there?
Just some thoughts,
Daniel

Yes.

Don't know, but it's not what I need, I don't want to pass all my
desktop, only my
320x240 pixels frame.

No. I must send it analog, the application on the other computer can't
read digital
video as an input.

All you need is a dumb VGA card with "TV out". It's getting hard to find
those, because they're obsolete, but they're in bargain bins,
surplus stores, and on eBay.
