Here come the 4K tellies

JoeZhang said:
High-definition TVs roughly quadrupled the resolution of the sets that came before them. Now, the industry is poised to do it again.

By December, U.S. stores will sell a TV set with four times the resolution of today’s best HDTVs, Sony Corp. said Wednesday. The set will measure 84 inches on the diagonal, making the screen area four times as large as the common 42-inch set.

Executives said Sony will reveal the price of the set next week.

There is, for now, very little video content available that can take advantage of the higher resolution. With some work and know-how, a computer connected to the set can display video in the ultra-HD “4K” resolution. The set will also do its best to “upscale” TV, DVD and Blu-ray movies, so they look better.

Obviously the first generation of sets are going to silly priced and content is going to be thin on the ground but we can look forward to people complaining that they don't want it and they will not be switching from bluray/dvd.

You rang? ;)
 
In the next, next, generation of HD TVs scientists can actually use electron microscopes in order to study the covalent bonds int he water molecules in the beads of sweat in the brow of a politician!

Seriously, at some point we're going to hit a wall where the finer detail is pointless because it's more detail than can be seen with the human eye. I suspect we're nearing there as it is. Sure there are plenty of times even on HDTV where details are still blurry or muddy but sooner or later we'll reach digitally the limits of what was captured originally on film. Then, say, we upgrade to these super-HD cameras and then we'll reach the limits of even what the human eye can see without aid.

Sure, maybe, someday a video recording of someone will allow the use of microscopes or whatever to study infinitely small details on a recording but what's the point in that?

The BBC had a demo of the Olympics in 8k(7680 × 4320) with 22.2 sound, which I got to see in Glasgow.

The picture was amazing on the 15m screen, not quite like being in the crowd more like being in the corporate box with glass between.
The sound was what I thought was the stand-out, when the crowd were cheering and clapping it was like being there. Not sure how I'd fit 24 speakers in my place though.
The BBC demo was using according to the leaflet I picked up 330 megabits per second.

Well this new Sony set is much higher resolution, but it is also 4 times the size that most people have now, which I imagine is the point. Not to make small TVs in excruciatingly fine detail, but to make TVs bigger.

I think those bemoaning the lack of content are missing the point as well. The standards for HDTV were put in place long before any HD sets were realistically available to the public, they started testing in the 70s, and that is what is happening here. They are betting on the future rather than just assuming things will stay the same, which is kind of what companies like Sony are all about.

This TV is coming out now "because they can", because it is good for their brand to do it. They are not trying to sell it to Joe Bloggs, they just want Joe Bloggs to see that they can and will develop this stuff.
 
This might explain the fact that a buddy just got a 38" for about $200 at Hhgregg this weekend.
 
Currently in the professional broadcast monitor world only about a handful of minitors are available with 4k.
4k projectors are available in many movie theaters.

4k tvs may happen but TV wont be moving to 4k as standard before 2022.
2025 is the time we are looking at for 8k UHDTV in the usa.
Wall-sized screens like in Back to the Future II will be how it goes with 8k.
Yes 4k screens will allow for multiple picture-in-picture viewing also how Marty,Jr. Watched tv in Back to the Future II. 4 1080p HD channels at once.
 
I'd be more excited if my local cable provider (Shaw) didn't compress the image so much. You can actually see the jpg type of blockiness. Kinda makes the HD pointless.
