Found this thread (
Why "super upconversion" should NOT replace Blu-Ray/HD DVD - Page 15 - High-Def Digest Forums ), where people talk about "super upconversion" with Toshiba and SD DVDs (upscaling). There are some promo pictures, I assume.
Now do this just mean the normal "NTSC/PAL to 1080p upscaling" or something more?
It just feels like cheating if Toshiba is marketing something that is just as good with e.g. PS3 and even with some more expensive SD DVD-players (upscaling)..
I have compared my PS3 and Toshiba with SD DVD upscaling, and they´re at least equal (PS3 looked a bit sharper in that time).
So what´s this term "super upconversion"?

Well full HD is usually used to differentiate 1080p from 720p or even 1080i.
Beyond HD is reaching a little, though you could argue it does the same. I think they want it to resonlate as "beyond broadcast HD" since the quality on media should be superior to over-compressed, over-filtered broadcast.
They have to do something to spruce it up and give people reason to watch something other than live HDTV. And they can't say "ultra," since there's already UHDTV, which is, what 4 times the pixels each way of HDTV, not that you're likely to see it in action anytime soon.

Re: HD DVD´s "super upconversion"??
First it was that "Toshiba is great in upscaling" in every forum and some people actually believed that it would somehow magically turn their SD DVDs into something spectacular and "close to HD".
Now it´s that "Toshiba does super upconversion"!
Oh boy, people sometimes believe what they want to believe..
(This doesn´t mean that Toshiba is not great in upscaling or anything. Just that many other players have quality upscaling/de-interlacing chip - not just Toshiba)
(..and SD DVD will never look "like HD", even with "super-hyper-Toshiba-upconversion" etc)
But perhaps those "masses" will believe that, that´s probably what Toshiba is hoping for..

Re: HD DVD´s "super upconversion"??
It is simply what they call their upconversion technology. They could have used mega wonderful, better than sony, or just different than the other guys upconversion technology.
Since when was there any truth in marketing, how many SE or Ultimate DVD's have left you scratching your head.
Bad thing is that if it works Bose may come out with Super Paper Cone Technology

Re: HD DVD´s "super upconversion"??
SD is SD. Up conversion isn't going to add detail to the image that isn't there. This business of "looking almost as good as HD" is hogwash. The only thing up conversion can do is help a low resolution picture look a little smoother on a screen that has more than twice the number of scan lines. It can help the transitions from one color to another be a little cleaner. And it can help prevent noise from creeping into the signal. It will be the best that SD can look, but its still SD The only way to get HD resolution is to feed the HDTV and HD signal.
I have a VHS/DVD recorder, and guess what, it up converts VHS to 1080i, but it still look like VHS.
HDMI 1.3 can support "Deep Color". And you know what, it can! Unfortunately there is no home video format thus far that can send deep color through the HDMI cable. So even though the these companies advertise Deep Color on their HD players, its nonsense, HDTV doesn't now nor will it ever support deep color. There will have to be a new format for that.
Don't believe everything you read with these marketing gimmicks. Most of it is smoke and mirrors.

I put a test pipe and a tornado on my PS3. The extra noise ticks off the neighbors but the extra 5 pixels is worth it

Re: HD DVD´s "super upconversion"??
Does Toshiba still use the term Colorstream (and Colorstream Pro, etc.) for component video?
That was kinda confusing when they first did that. Everyone wondered if it was somehow ever so slightly better than standard component video.

I think they may still use Colorstream... it has been awhile since I was asked about colorstream compatibility with a component capable TV

If I understand correctly, Deep Color = 4:4:4 component (YCrCb) video while current HD formats continue to use 4:2:2 (like DVD), which is 1/2 resolution for the 2 color channels.
However, I wonder if future HDM titles can't actually use Deep Color above the current specs though. Do the existing specs actually make the option impossible? Of course, even if titles can be produced w/out breaking the specs, that doesn't mean existing players will output Deep Color (or even be able to play them at all). And of course, you'd also need HD displays that can handle Deep Color, if so.

The problem isn't HDM, it's the actual HDTV specs that don't allow for deep color.

Ah. So are you saying HDM does support Deep Color, but we just need actual HDTVs that support it also? If so, I can see the double-dips coming for HDM titles w/ Deep Color as soon as TV makers decide to add Deep Color support on top of the HDTV spec.
Maybe at that point, BDs will be "Beyond, Beyond HD"...

Well a display format that supports Deep Color won't be HDTV, it might also support HDTV, but it will be something else all together. Kind of like how HDTV also supports NTSC.

While I do concede that no upconverted DVD will look as good as its' counterpart on HD-DVD and/or Blu-Ray some can look damn close to HD on the right player(such as the Reon equipped XA2). I've seen DVDs on the XA2 look as close to HD as possible so I don't quite buy the "hogwash" statement. Like I said, Blu-Ray and HD-DVD are obviously superior to standard DVD, but the XA2 does an amazing job making some DVDs look better than I ever thought possible.

Re: HD DVD´s "super upconversion"??
SD has 480 horizontal lines of resolution, HD has 1080. Thats more than twice the resolution. Upconversion doesn't magically add detail to the image where it doesn't exist.
When you see the picture in picture commentary on HD DVDs, the image size of the commentary picture is no accident, that accurately represents the SD frame in comparison to an HD frame. That is how much an SD image has to be enlarged to fill and HDTV screen.
Again all you have to do is look at the fine print in the title sequence of almost any film that is available in HD and SD to see the difference.
There are some excellent screen shots taken directly from SD and HD discs here.
Blu-ray, HD-DVD & SD DVD Comparison Screenshots *WARNING - LARGE PICTURE FILES* - Page 2 - AVS Forum
Of course they aren't moving, but the are full rez HD and upconverted SD of the same frame from various films. The difference is really rather startling. Also these are computer captures not screen shots taken with a digital camera.
Yes upconversion looks great. It's the best that SD will ever look, but to say that it looks close to HD is just not realistic.

Well, to be fair, I did say "some" DVDs upconverted can look "close" to HD and this was strictly on the XA2(the best upconverting player out there) so there are many differentiating factors in play. I think we're in total agreement that HD is ALWAYS going to look better than SD DVD, but I still think that "some" DVDs have an almost HD-like quality when upconverted on the XA2. Just my .02 on the subject.

Actually the resolution of SD = 640x480 = 307200 compared to HD = 1920x1080 = 2073600. Which means the resolution of HD is 6.75 times that of SD. Absolutely no comparison and that's just in terms of resolution. I suppose the only time upconverted SD can look comparable to HD, is when it is viewed on a relatively small and a not so well calibirated display monitor.

Actually the resolution of NTSC, or SD as it is formulated in the U.S. is 720x480. 640x480 is a computer monitor resolution as it unrelated to NTSC.
