what about 1080p upscaling our content not in the display, not in the AVR but in digital media players (just before outputting the content via HDMO to the AVR and/or display?

world's leading digital media player chipset manufacturers like realtek (chips: 1283, 1185, 1186) and sigma designs (chips: 8640, 8650, 8670 series) implement upscaling levels upto 1080p. is it only software algorithms they use? and is it comparable (of course only to a certain extent) to what the video processor like faroudja, abt, hqv do?

do you have any tehcnical details about the video upscaling features of the above chipsets and should we "not upscale" the content in the media player and leave it as it is before outputi in order to make the AVR or the display do the upscale?

you can use testcards and test sequences available on Video Essentials,
Spears& Munsil and other Reference Discs to see the difference.
The Video Processors sometimes do a better job in difficult interlaced
Video like Film (24P) mixed with Video titles or some other video materials
(Sports with on Screen Overlays) . if you only watch Movies with 23.976fps
or 24.000fps , the different media player chips do a good job.
I also use a Media Player (PCH C-200) with a Crystalio II and a Radiance XS+3D. in some cases, I prefer the Crystalio II (especially for SD sources)
and the Radiance for HD 72/75Hz tripling the org. 24/25fps framerate.

There's a great Japanese Reference Disc put out by the Plasma Supporters
that really show the shortcomings of most chips and processors.

There a Guy in Germany (Burosch) that offers the most difficult test patterns that are on the planet.
He created Test Patterns for the PAL systems since the B&W times.
I know him personally. He creates the best Test Material for any Display type.
His Expo Demos are legendary here in Europe

He proved that even 2 consecutive LCD panels don't look the same side by side.
