7-pin composite-like connector

[Cartoon Moon]

A very happy x-mas to all !!

I'm searching for information about the tv-out connector I have hear. It looks like your regular composite-S connector, but instead of 4 it got 7 pins.

They look a bit alike:

I visited some of my 'nearest computer dealers' and they had some opposing idead. Two told me I needed some special kind of cable, but one told me a regular composite-s cable would do, and apparantly it does. The colors and everything are there.

Does anyone have more information on this kind of connector ?

Thanks !!

PS: sorry for the crappy asci-art
