Sharp, Toshiba and Sony release 4K2K Quad-HD TV and Projectors

Posted by Charbax – October 12, 2011

At the recent CEATEC consumer electronics show in Japan (which I had tried to attend and video-blog at but I did not find a sponsor in time), Sharp, Toshiba and Sony showcased their first consumer-oriented 4K2K screens and projectors, perhaps finally leading up to more 4K2K for the mass market. Eventually more affordable, because Toshiba's 55" Regza 55×3 Quad-HD is announced to be priced at over $10 thousand. Sony's VPL-VW1000ES Quad-HD projector is even more expensive at upwards $20 thousand. Sharp did not yet announce a price for their 60" Quad-HD TV, but they showed what they call their new so-called Integrated Cognitive Creation (ICC) processor for what they claim to be higher-quality Quad-HD upscaling.

4K2K is awesome. And putting it on 55" or 60" screens and in projectors sounds like a good target. They need to sell 4K at sub-$2K. They need to price 4K at $2000 and below and not $10K and they need to mass produce 4K2K as a priority now instead of 3D.

The 4K content solution:

On the Internet, the most downloaded 1080p movies are below 10GB per movie. That means 4K movies can be compressed at a below 40GB file size. That means that a 4K movie can fit on a current Blu-ray disc. That means that more than 50 4K movies can fit on a $50 2TB hard drive.

There is no 4K distribution problem.

YouTube supports 4K streaming at below 20mbitps today.

The most downloaded 1080p movies are encoded at below 9mbitps bit rate. That means that a 4K movie can be streamed with a 36mbitps or faster Internet connection (at same "full" quality level per pixel), which more and more people can access today using a regular VDSL Internet connection over copper wires and even faster over the coaxial based network. Millions of consumers already have Fiber internet to the home, and millions more could easily get it. Those people can get 1Gbitps over the connection, that is more than enough to stream any 4K content needed.

Hollywood has already digitized most of their 35mm movies to the 4K2K format, which is already becoming the digital standard for Cinemas worldwide. And most of the new movies are being recorded using 4K2K cameras anyways and are already natively recorded in that format. So it would actually be a piece of cake for the film industry to provide every movie ever made in the 4K2K format, easily distributed on Blu-ray, on hard drives or streamed using 36mbitps or faster home internet connections and progressively downloaded using slower connections (if you only have a 20mbitps download ADSL connection, you may wait about half an hour before the 4K movie can start. Or you can get the 3K version at half the bitrate and that still would look 2x better on a 4K display than the same content in the 1080p format).

It is very common for all consumers to take digital pictures at 8megapixels or higher. Most new digital picture cameras take 8Mpix pictures or higher today. Even most new high-end smartphones take 8Mpix pictures. put the SD card from those cameras in your 4K2K TV, and for the first time, you can see the full quality of your digital photographs. Just to display your personal photography onto those 4K2K displays wil be worth the enthusiasm, even if you do not have fast enough Internet, even if you can't get a lot of 4K content on Blu-ray or directly onto hard drives, then still just as a picture viewer, the demand for 4K2K is worth it now.

Dear TV industry, please stop making 3D now and start mass producing 4K2K screens and projectors now! Get the price down below $2000 as soon as possible, than you.

    Mhh … the scaling from 1080p to 4K for file size, or Kbps for streaming, that you did hasn’t convinced me… You made a x4 multiplicatin, but moving from 1080p to 4K the pixel count is not 4, but about 16 times, I think. So is (more or less) the byte count, before and after compression. Isn’t it?

  • can’ twait for 4k2k tvs to become affordable.

    You are mistaken…!! It is correctly 4 times as much data (2 x 2 = 4 as 3840 × 2160 both are exactly twice of 1080P).

  • My personal dream: 4K projector with 10,000 lumens, 50,000:1 contrast ratio, 105% NTSC color gamut, LED or Laser light source (50K hours lifespan and low power consumption) 2.35:1 native aspect and a 60° or wider projecting angle, so it will work with large screens without having to be more than 10-12′ away from the screen.
