Yes and no.
Practically, yes. You'll see the terms used interchangably.
Scaling is the process of re-scaling a video source. For example, DVD is natively 720x480 (for NTSC sources). If you converted that to 1024x768, that's scaling. Even if you converted it to 320x240 or such, it's scaling.
Processing is a more general term, and can refer to a bunch of things (deinterlacing, scaling, etc).
2. DVDO iscan HD is a scaler??!!! ... then which are the processors??!... faroudja DCDi ??
DVDO IScan HD is a processor which scales. It also deinterlaces.
Faroudja DCDi is a technology which helps with deinterlacing video sources as opposed to film sources. See the FAQ for descriptions (3:2 pull down, etc.).
3. sooo... if i have a $100 dvd player (panasonic s47) and i use DVDO iScan HD , wud it give better results in video than $3000 dvd player ??... as in better black levels, good images,colors etc etc. ??
It all depends on what the $3k player does.
Remember the old adage of "garbage in, garbage out" - a processor can't create new information - it can only reinterpret the existing video signal. So, while it can make the signal appear better, it is an illusion - there is no more information present than in the original signal.
So, the question is more one of which DVD player/processor combination produces a better video - the $3k one, or the $100 one. And it doesn't all depend on price - back in the day, there were Panasonic models which ran $300 or so which were top of the line, beating out much more expensive alternatives.
Hope this helps,
