Does the Pioneer VSK-32(Marvell Qdeo) support digital upscaling?

I have tried searching Pioneers, Marvell, and the rest of the internet for this but my question was never answered explicitly.

Pioneer says:
Pioneer has long been the leader in video processing and combining. The VSX-32 benefits even further with Marvell's advanced Qdeo video processing, which lets you upscale your picture to digital 1080p/24fps from virtually any source, including analog.

Marvel says:
Today, innovative technology enables consumers to customize their lifestyle by working with various avenues of media that best fits them. However, this in-turn requires handling of a wide variety of material ranging from:
...
digital cable at a variety of bit-rates
HD broadcast at a variety of formats and quality
SD (DVD) and HD (Blu-ray) optical media
...

Reason why I want confirmation is I bought the Denon AVR 791 then realized the ABT 1xxx only upscaled from analog. It wouldn't make sense for me to have my HD box connected through component to use the upscaling feature for SD channels yet downgrade the quality on my HD ones.

Also, it seems that consensus on the web for video scalers is: Reon HQV>Marvel Qdeo> ABT. In that case, too bad the only Onykyo uses HQV although I did find a retailer selling the 876 for less than one grand but none of them ship to Canada.

Thanks in advance guys.

Confirmed. Pio converts signals from HDMI.

IMO upconverting is not only desirable but necessary in an AVR. All but the entry level AVRs will upconvert. Upscaling isn't near as important IMO because most displays upscale to their native resolution as well - and often better than an AVR.

Well I beg to differ I think the SDTV and DVD upscaling on the Marvell is better than my TV (I think most 1080P TV are not good at up-converting 480i signals My 5 year old Pioneer Plasma did a better job on SDTV and DVD than most of the current displays) I agree analog to digital conversion is necessary now.

I too have been disappointed with the upscaling (if you can even call it that) of both my Pioneer 5020 and Sony XBR9 when it comes to standard def via D TV. The Marvell in the 1120k does a better job and you have many more adjustments at your disposal. As for which chip is better I have yet to see any thing perform better than the ABT chip in my Oppo 83 - too bad I can't use it for SD too. Some day AMC will be in HD on D TV.

Supports digital upscaling?

A product that has digital output supports digital upscaling. My iScan VP 50 has ABT chip and it takes in analog and digital without discrimination and outputs HDMI.

Your Denon 971 can input both analog and digital and its video processor will upconvert and output through HDMI.

Your mistake is in the notion of upscaling. "Upscale" in regular English means "improved, upgraded," for example a Lexus is an upscale Toyota, an Acura is an upscale Honda, and an Infiniti is an upscale Nissan.

In the world of video products, "to upscale" means "to convert picture as needed by the display." This conversion doesn't improve the picture, although the properly upscaled picture seems better detailed.

For picture improvement, you have to add info, add more detail, and a processor can't fabricate info that's not there. A video processor can't upgrade SD DVD to HD DVD or BD DVD but a movie is great stuff anyway.

To my understanding, the 791 and below simply pass through HDMI so it is not converted or scaled even thought one may want for SD channels. Also from what I have read, the video processors by ABT, Reon, and friends precisely do what you stated: they take existing information and take a best guess to add information to improve picture quality.

Thanks for the help guys.

The models below yours (591/1611, 391) simply pass through HDMI, however, the 1911/791 and above will indeed upscale HDMI video. Simply set the i/pScaler setting to either "Analog and HDMI" or "HDMI" and voila ... you get upscaled HDMI.

Thanks for the clarification. I thought the 791 could not upscale from an HDMI source but after combing through the manual a few moments ago, I realized it could.

I thought otherwise because of this website:
The Pioneer and Denon send unmolested video signals via HDMI, but can only upscale analog sources.
