S Video connections, plugs, cables, etcetera etcetera.

I noticed that on my dead nVIDIA GeForce4 Ti 4200 video card for the TV out has a unusual connection. Unusual to me that is. It is a seven pin connection. Any has information to share? Does the seven pin S video cable have more grounding than a four pin S video cable? A schematic for the seven pin S video cable would be nice.

-TIA

I can't help you there but please tell me that little picture is not the label of a Commodore VIC-20.....

or worse.. that you use it and get real time encoding

It will use a standard S-Video cable for S-video, and with the aid of an adaptor (usually supplied with the card), the middle three are for composite video (I think thats how it goes, but I have been known to be wrong before).

That's the VIC-20 alright.. ..one of MY first computers, the VIC-20, he, he...
I remember staying up late fri/sat nights, drinking lots of coffee and
plugging in code from PC Magizine, etc... ...

VIC-20, C-16, C-64. . .

As to the nVidia card, just so happens that I picked one up today to
replace my old 2 year old ATI Rage 128 PCI card. And, I noticed the
same thing. Turns out that it's an S-Video OUT in your's and my case.
The ADVC-100 DV device has this same plug, but it's an IN, but I don't
know why, when this unit has an IN on front and back aready.

But, on the nVidia card, it's the OUT for a Composite or RCA connection
to your TV set (yellow circled plug) If you have an S-Video TV equip, then
you can just use the 7pin S-video OUT to your TV's S-Video IN.

I've ben meaning to test this OUT connection on the nVidia card to see
if the TV out quality is better than what I have in my ATIRageFuryPro
card's TV-OUT, or maybe they are just the same output quality, no
matter what. But, I'll be testing it anyways.

Some cards i.e. mpeg decoders and some TV cards have a non standard 7pin mini jack.

By non standard I mean you cannot get the plug anywhere to make up the lead or connector as it is custom.

Sometime you'll have s-vhs and composite or composite and audio and you should have been supplied with a lead.

Some of the budget computer suppliers neglect to include leads for these connects are hoard them for themselves.

You know these manufactures when you order a replacement zip disk your supprise to get a zip tools disk with no box as they have removed them from the zip drives they sell

I can still use my VIC-20!!!
Anyway the 7 pin S-video plug works well with a 4 pin S-video pin. I just put the for pin cable into the plug. I do have another question, or statement. For my old Apple LC or LLG the mouse cable has the same connection as a S-video plug. Even fits in one. strange isn't it?

Does anyone have a schematic for the seven pin S-video cable that would be willing to share? If not any ideas on where I can find the schematic?

[BJ_M]

this is one pinout - there are more ... its not standardized between companies (graphic board companies that is)..

btw - a 7 pin s-video connector is a standard connector for semipro equipment .. and is easly found and purchased -- but of course ati and nvidia dont use that pin out ...
