Hello, im wondering if there is some device that will enhace the video of a normal device such as nes or ps1 or old satelite to a hd state so it looks good on a HD tv.

If im not explaning to good here a more graphic example. Connect video/yellow audio/withe&red of my oldie (nes, ps1-2, stalite) to a device that enhace the image and makes it looks good in a HD screen and not like crap like what i get when connecting directly. Some brands recomendation please. If i cant do this, i wont buy hd tv till i can.

Thanks

That exists, and it is named "scaler". DVDO Edge for instance.
But it is quite expensive.

Anyway, all screens have an internal scaler, as they can't display picture in an other resolution than their own panel one. So you "just" have to buy a screen good in this matter (Sony Bravia, LG...)

Thanks, for what ive checked buying a good hdtv + scaler (dvdo) costs lot less than just buying latest LG or sony with great scaling. Have you seen in live action this devices or just heard of them?

The best way to do this is to run emulators, which are often better than the original system itself.
Try that with an advanced system (XBOX 360, Wii, etc) are a high quality cable.
