Default S-Video to RCA adapter


Anyone know where to get one cheaper than $20 with shipping from ATi?
Will any old adapter do? I've heard that ATi is kinda picky when it
comes to adapters and the one I've got from Radio Shack either doesn't
seem to be working with this particular card, or my card's messed up.
Either could be a possibility.

Thanks,
Andy

The 7-pin type is required because it is not just adapting the signal
but actually has both incorporated into the connector (as opposed to
normal 4-pin S-Video). You could try eBay.

....or ATI uses a different pin configuration then the standard from
Radio Shack. I have one for an older ATI Radeon and if I remember
right, the pins were different. I did find the pin locations
somewhere, but I don't think it was Google. If I come across the link,
I'll post it.

A standard S-video works with the 9700, but if he has an older
adapter it might have the different pin locations. I have an S-video
adapter that came with a Radeon 64 and it won't work with my 9700
because of the different pins.

S-VHS is a VCR format. The machines have have S-Video connectors on
them. The older Radeons usually had both RCA and S-Video jacks because
there was room for 'em on the plate. Those with DVI only have the
S-Video/combined RCA jack that requires an adapter if the RCA output
is used. On my 8500, a common adapter produced black and white output.
Only the ATI 7-pin worked correctly.

S-video has nothing at all to do with S-VHS.

As the earlier poster put it, S-video runs separate cables for chrominance
and luminance, which solves a host of problems with higher resolution color
video, compared to composite video in which both run on the same cable.

S-VHS refers to a higher-end VHS tape recording format.

It does actually.

It was introduced by JVC at the same time as they introduced s-vhs and both
s-video and s-vhs share the same philosphy; i.e. to keep the luminance and
chrominance signals separate in order to avoid interference.

Yes, many people confuse s-video and s-vhs. But to say they have nothing to
do with one another is an overstatement.
