Tell me more about this "Shield" on a J Scart, please

[Blaine]

I'm fixin' to build a Japanese SCART adapter for my enroute video scaler. I'd never looked before at the pin out, I mean... really looked. And I'm slightly confused, maybe someone can help me out.

The scaler I bought wants RGB plus some sorta sync (H/V, Composite, Sync on Green). It expects 6 pins on a 15 pin mini d-sub.

Pin 1: Red
Pin 2: Green
Pin 3: Blue
Pin 5: Ground
Pin 13: Horizontal (or H+V)
Pin 14: Vert

So am I just to ignore the 'shield'? I don't even understand what that means.

Is it

JS: 15 - DS: 1
JS: 19 - DS: 2
JS: 20 - DS: 3
JS: 21 - DS: 4
JS: 9 -  DS: 13

Or am I gonna have to do something whacky with the signal and the shield?

I might be over analyzing but.. I'd rather not destroy the video scaler the second I get it. It'd be cool to use it for a while.

The 'shield' would be the ground.

Thank you.
