In Reply to: Question for I-Scan owners posted by JoshK on February 22, 2002 at 13:21:20:
The Iscan's de-interlacing capability is much superior to most of the DVD's internal de-interlacer. For film, it auto-detects pretty well, taking care of subtitles on DVD which are not at 3:2 rate.It will also help in video based source, especially on things that has alot of motion like sports.
But, since you have a plasma that has fixed pixels. You might be better off with a doubler/scaler combo like the Quadscan. But the Quadscan is not as good on doubling as Iscan, so most of the time, you would have to manually set it to film or motion based source. Plus Quadscan does not work on parts of an image like Iscan, so if one part of the screen is in motion, it will use the same algorithm on the whole screen.

I guess I need to read up some more, I really don't know very much about video processors. So if price weren't the major issue which processor would you recommend that does all/most things well for a plasma?
Processors does de-interlacing (doubling,) scaling to your panel's native resolution, various filtering, noise reduction and picture cleanup.Probably the hardest part is de-interlacing, and that is where the native display's build-in unit are at its worst. With a doubler like the DVDO, it will do the de-interlacing, and the display will do the scaling. With a scaler, it will do de-interlacing and scaling. The misc stuff like noise reduction depends on the individual unit.
A good bet for fixed resolution device is a Faroudja NR. It only has 1 resolution, but you only need 1. It has excellent de-interlacing and scaling capability. It goes for $3-$4k. Price no object would be the Teranex, which goes for > $30k, but has 1000x the computing capability of something like the NR, so it could do video de-interlacing on a pixel by pixel basis, applying different algorithm to each pixel, depending on what that pixel's temporal properties are. Whereas the NR would apply different algorithms to different region based on a field of info, the Iscan would do a region based on a frame of info, and the Quadscan would apply the same algorithm to the whole frame.
Great info, I am just learning about video. Spent the last few years learning about audio and just started video recently. Your explanation I find very leyman and what I was looking for. The Faroudja is a bit out of my range currently. I think I will deal with it for now, wait till I buy a place and see if I can't get HDTV sat broadcast. I find a good DVD player has a great picture on the plasma and I have not yet seen a need for improvement on this front, however, cable leaves something to be desired.
