It's called a Scaler and the "iScanPro" is one such part.
But your TV automatically up-scales the video to it's own internal 720 or 1080 resolution so the outboard scalers dont really improve anything.
Standard Def video is from the 1950's designed to compress a nine-inch screen. You can magnify/up-scale the doll - but you cannot add information to craft these channels look dutiful on a high res display. Yes, in attendance should be a setting on your HD box (satelite or cable) for how the signal is output to your TV. Choices are usually 480i/p, 720p, and 1080i. Sometimes there is a "native" setting so that it will of late output the original resolution of the program. Since you enjoy an HD box and an HDTV, you probably have a scaler contained by both. It's usually recommended to set your HD box to match the original resolution of your HDTV. You could also set to "native" on your box and let your HDTV to adjectives the scaling.
The switch is to scale the picture as few times as possible, i.e. once. For example: let's right to be heard you're watching a standard def show that's presented in 480i and you own your HD box converting it to 1080i but your HDTV has a local display of 720p. The TV has to size the 1080i back to 720p to show it, so the pictures is man scaled twice.
Hopefully I've given you some philosophy and you can play around with the settings on your HD box and HDTV and see what you resembling better. Good luck!
