Ultra High Definition Video
hovermike writes "This story about UHDV (Ultra High Definition Video) comes from the NY Times. Here are a few specs from the article: 'picture size of 7,680 by 4,320 pixels'; 'UHDV's beefed-up refresh rate of 60 frames per second (twice that of conventional video), projected onto a 450-inch diagonal screen with more than 20 channels of audio'; '22.2 sound: 10 speakers at ear level, 9 above and 3 below, with another 2 for low frequency effects'; AND THE KICKER, 'All those sound channels and all those image pixels add up to a lot of data. In test, an 18-minute UHDV video gobbled up 3.5 terabytes of storage (equivalent to about 750 DVD's). The data was transmitted over 16 channels at a total rate of 24 gigabits per second.' Don't think I'll wait to buy regular 'old' HDTV..."
So *that's* what powers the view screen on the Enterprise. Cool! :)
The post-production touch-up jobs on porn acresses is going to have to get a *lot* better at that kind of resolution!
Please note: first thoughts != best thoughts
We're about a decade away from reaching the point where there increasing the resolution of the screen will not be detectable to the human eye, at which point, one could go about collecting a collection of Ultra-High Def DVD's without worrying about a 'better' version coming out soon. So you can get all of your 20th century and early 21st century media and know that your great grandkids will view it exactly the same.
I have to change my underwear now.. and have a smoke...
I have been a user for about 10 years. This ends Feb 2014. The site's been ruined. I'm off. Dice, FU
I like the resolution and all, but in all seriousness... with ever decreasing space for our living, this is not exactly customer product. Your 68" tv does not need such high resolution, I hardly have space to put my 5.1 system in the 2 bedroom condo I am staying in...
Even if the price is within our reach, this piece of technology is going to be left to corporations and ultra rich people with lots of real estate. I fail to see point of having this, except for new digital cinemas.
My god, watching the latest holycrud with mind boggling resolution...

On the other hand, perhaps this may be better as an educational tool:
"And here you can see the distribution of Influenza cases superimposed across this landsat image lower manhattan... and my apartment. Hey! There's me! And I have the flu."
The power of modern GPU's could be put to use with this resolution, and we could once again have a resolution war between the various chip makers.
Let's learn to "walk" with images of this resolution, before we try and run.

Damnit!

well, that's one way to keep people from sharing the files...
Anybody got a bittorrent link to the 3.5 terabyte file?
What, only 2 dimensions?
Synergy is your friend
What kind of porn are you watching, anyway, where they bother with post-production touch-up -- or plot, for that matter?
...When we were doing text, people thought having 100kb pictures would keep them from sharing.
...When we were doing pictures, people thought having 3mb music files would keep them from sharing.
...When we were doing music, people thought having 100mb applications would keep them from sharing.
...When we were doing applications, people thought having 700mb movies would keep them from sharing.

Information (as in raw bytes/sec) will continue to become cheaper and cheaper. The price of content is quite stable. Add 2+2 and see where it is going. More, faster and more "profitable". I know several people that are probably "millionaires" by now.
At the estimates for piracy, using the full penalty of the law, the total piracy is more than the GNP of the world - not just this year - but (estimating like a geometric sequence) for all eternity since the dawn of time.
How's that possible? Simple. We make "money" out of thin air. You give me a million, I give you a million, and we both keep it as well. At $0/content, we could all have all the content in the world. So the loss = 7 billion people * millions of CDs/DVDs/Apps/Games/whatever * full retail price. Yeah. Right.
Copyright will have to change because pretty soon everyone will have millions in liability - it will simply be common. I've seen it in every age group from 8 to 80, both sexes, all sorts of people. It's bigger than prohibition in the sense that "everybody" is doing it. There's simply no stopping that.

I can understand the incredibly high resolution, but why so many audio channels?
Two channels does quite a good job of reproducing all the sounds of an environment, assuming the stereo speakers are appropriately far apart.
5.1 channel sound added a sub-woofer, which is a positive development, and then 3 more speakers. Okay, the two rear channels I can understand, because most people don't have their speakers located well, and there's a certain gee-wiz factor in hearing something that is distinctly behind you. However, the center channel still makes little sense to me, since the stereo speakers can handle that area just as well (center channel is usually a crappy little set of treble-only speakers anyhow).
Now, I am really at a loss to understand why you need even more, especially 20+... Put on a pair of stereo headphones and pick any location, 360 degrees, and I'll make it sound like a noise is comming from that exact spot. So what can 20+ channels do for you?
Even if we start getting holograms comming out of the screen, I could still make a sound seem like it's comming from whatever position that object is located with just 4 speakers, and I could do a pretty good job with just 2 if needed.
