S-video doesn't handle RGB signals. That's why you need a scart cable. Alternatively you can use a component cable I think. But what he means is that you need a custom cable to get RGB signals out of it. So you need to order that from somewhere as well. Since it's going to be hooked up to a framemeister (which is made in and for Japan) I assume that means you can order a JP21 RGB cable. JP21 connectors are basically the japanese SCART standard. Even so I think you also need an adapter for the JP21 cable to hook it up to the upscaler since the framemeister doesn't have JP21 connectors on it.
