RCA Question...

This is the closest tab to my question...

I was thinking about trying to make a program that
would function just like an RCA video out, except
that it goes through the soundcard (RCA is all
waveform, including video) It would put out the
waveform that would go to the TV as a picture,
because then you wouldn't need to go out for a
new video card. My problem is this:

I cannot find any docs online that will explain how
this works, and how it all comes together. I've heard
that the frequency works as color, and amplitude as
intensity, but beyond this (Such as individual pixels,
and definition/resolution detection) I don't know.

I would appreciate any links you could provide...

    This really isn't graphics programming related, but I'll leave this thread here. You cannot do what you're asking without at LEAST writing a custom driver for your soundcard, and more likely without being able to modify the firmware on your soundcard. I suppose you could write a program that could convert video into waveform and send that to the soundcard as that waveform, then run a line from your line-out to your video-in on the TV, but the video waveform may be out of scope (too high or low-pitched sounds) and some of the wave may be clipped by the hardware or driver.
