Japan trying to make HDTV Obsolete

TOKYO ? Aiming at next-generation broadcasting, Japan Broadcast Corporation (NHK) has demonstrated a live relay of a 4x x 8k resolution Super Hi-Vision program connecting a 260-km distance by a fiberoptic network.

NHK's next-generation broadcasting system can convey the sensation of reality to viewers. Super Hi-Vision is the provisional format for that purpose, achieving 7680 x 4320 pixels.

It already demonstrated the images of Super Hi-Vision at the 2005 World Exposition, Aichi, Japan, held from March to September in Aichi this year using a preliminary prepared video footage.

NHK developed a Super Hi-Vision camera equipped with 8 megapixel CCD image sensors that can take 4k x 8k images. In the field test, it sent the two cameras to a sea park and sent baseband signals without image compression using an fiberoptic network formed by multiple network companies.

The signal of the total 24 gigabits per second was divided into 161.5 Gbps HD-SDI signals to sent using the DWDM (dense wavelength division multiplex) method.

"Super Hi-Vision has huge information and was difficult to transmit. Using 16 waves on optic fiber, we succeeded a live relay over a long distance. This means that Super Hi-Vision proved the possibility of being a future TV broadcasting technology," said Mikio Maeda, senior research engineer of the laboratory.

I remember walking into a Japanese department store back in 2002 and having my jaw hit the floor when I saw the TVs there. When I saw the prices, my jaw fell off, but the picture quality was out of this world. They have some cool stuff over there about two years before it appears here.
 
it's totally unrealistic to expect people to have DWDM fiber optics to their homes to watch TV in the near future; the cost would be enormous.
 
I think HDTV is just about enough for normal people. I'm all for advancement, but be realistic. HDTV is relatively new, and it's great. No need for someone to come in and say, here, not good enough. It's perfect!
 
Think of the percentage of current HDTV owners verus the vast majority of regular TV owners still. It'll take awhile before even HDTV is the norm, let alone fiber optic networks replacing cable and phone, let alone AGAIN this new kind of TV.
 
Once again they chase numbers and have no idea about quality or the human eye.

But hats off for the advancements in video technology that we've seen in the last 7 years.

-edit-
And using DWDM at 16 lambdas to the home is just ludicrous.
 
Only the japanese would name something Super Hi-Vision.

Japanese must not translate well, haha.

HDTV will only be eclipsed by rate of adoption by the DVD (the all time winner). Its on par to take over the DVD.
 
Is this the same tech they were bragging about a few years ago where the images look real? Where it doesn't look like a "picture", but that you could walk through the screen because it was that realistic looking?

I definitely think HD-DVD or Blu-ray will catch on fast for anything being put on media, but I'd give it awhile still before MORE people own hi-def TVs than regular TVs.

heh, we'll see.

The DVD broke all the rules. the number of sales of HD vs SD TVs should be a good indictor. (see sales of DVDs and DVD players vs. VHS rentals and sales)

Its never been a better time to be into AV than right now. Its amazing really the advancements that are coming out year over year. I've been a proud owner of a HDTVs for over 6 years and have enjoyed watching the progression and adoption. Especially after going through the laser-disc.

Simply amazing.

Nah, that's what we call High Definition.

Nothing compares to the cost and creation of the US highway system.
 
grumble. we don't even have hd media formats yet. maybe they should concentrate on making sure that roll out isn't totally bungled. where its going now doesn't look pretty with the draconian copy protection and format wars bullsh*t.
 
I remember watching HDTV at the Sony Center(at the Ginza) 18 years ago and was highly impressed then. This summer, I was there again with my family and you should see some of the new camcorders coming out of Japan soon - it will knock your socks off...

And we all know the cost of technology never decreases with time. 😕

Hey I was there over summer 🙂

Some very cool stuff 🙂

Don't worry about HDTV becoming obsolete anytime soon. We don't have a fiber optic infrastructure ready to broadcast widespread signals like that, HDTV's still aren't in the "everyone can buy one" price range yet (can you imagine what these things would cost?), and TV stations just started accepting HDTV last year. If this new technology gets produced, it won't be in living rooms (at least in the US) for at least a decade.
 
I have a 50" HDTV and my only gripe is the lack of enough HDTV programming even though the majority of real estate at BestBuy for TVs is taken up by HDTVs... Watching standard def TV on a HDTV looks horrendous. They should just cut off standard def TV which will force people to buy HDTV and it'll also cause the price to come down. But, I know I'm only dreaming.
