What is this exactly? Worth it? Can it be hooked up to an existing
DVD player? Heard about them (scalers) but do not have a clue what they are about. thanks in advance. peace, warren
Follow Ups:
An upscaler can do a couple things like take 480i (interlaced) video and create 480p (progressive scan) video. Modern DVD players already put out a 480p signal which will work with most recent TV sets that can handle 'progressive scan' input. Beyond that, some upscalers will actually take the 480 signal and upconvert it to 720p, 1080i, or 1080p which are higher resolutions. By upconverting the signal you are not gaining any additional detail or information. The upscaler is basically filling in, in-between the lines. Some DVD players have this capability built-in. The Denon 5900 and others can do 480p, 720p and 1080i, others might even do 1080p but of course your TV/monitor will need to be compatible with these formats.In my opinion, if you have a 'high-end' home theater setup with a large screen an upscaler might be worth the investment but it's really the source material (the DVD itself) that is limiting the picture quality. I can 'upscale' any DVD I own and none of them look even remotely as sharp as a true High-Definition TV (HDTV) broadcast with HD source / content.... Live NFL games for example or PBS programs shot in Hi-Def. Hi-Def is also 720p or 1080i but because the source was shot at those high resolutions, all the information is there as sharp as can be.... something that DVD can only 'imitate' with upscaling.
So to invest in a upscaler today or not? Hmmm, not me. Even modestly priced DVD players can do that. The real hot ticket will be higher resolution DVDs which are just around the corner.
Just my 2-cents worth from a layman's perspective.

(see link)--it does a fantastic job of creating a cinema-like image.But I'm considering getting the iScan HD, which has many features that the iScan Pro doesn't, including "infinite" aspect-ratio scaling.
I'm not interested, at this juncture, in ordering one, such as the website you provided. I would like to know what they do. "cinema like image?" What do you mean exactly? Can you be more specific. thanks, warren
line-doubler, video scaler, de-interlacer.Basically, a scaler/line-doubler turns the interlaced NTSC signal from the DVD player into progressive video, in the process removing the scan lines, or at least making them a lot less noticeable. That's why the picture from a line-doubler is often called "cinema-like."
Many monitors nowadays have built-in line doubler circuitry, but the best performance is assured from a separate unit such as the DVDO iScan Pro. Better line-doublers will have a feature called "3:2 cinema pull-down" (or similar wording) that corrects the problems (motion artifacts, etc.) that result when the 24 fps of cinema are converted into 30 fps (60 when interlaced) on conventional video. It's a complicated subject--you can read all about it here (see link).

I responded to thread over at www.audiogon.com asking for someone to post a link to better define what they actually do. All I know is that the picture resolution goes WAY up. "Cinema-Like" is a good term.There are many models to chose from, some are fairly inexpensive and some are quite expensive (like the big Farouja).
What's your budget?
P.S. Thanks again C.B. for ther link. I'll check it out later.
