NHK Working To Make HDTV Obsolete

Posted by Zonk on from the tech-doesn't-stand-still dept.

An anonymous reader writes "According to an article at EEtimes.com Japanese company NHK has successfully demonstrated a live relay of 'Super Hi-Vision' television, which is 16x 1080i resolution -- 7680 x 4320!" From the article: "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."

    For this I am assuming 1cmx1cmx5mm for the size of Samsung's 16Gbit flash chip. This is probably slightly larger, but we must include the board on which they are soldered

    People made do with huge VHS tapes for years, right?

    So lets see how much storage we can cram into a VHS tape using flash.

    first lets gets the area of a VHS tape... 7 3/8 x 4 1/16 x 1. Thats in inches. So, lets use Google to calculate that into cubic centimeters.
    Thats about 491 Cubic centimeters.

    Now lets see how many cubic centimeters a single flash chip is.
    Thats 0.5 cubic centimeters. Now lets divide 491 by 0.5.
    Thats a whopping 982 flash chips!

    Now, how many gigabits of storage is that?
    15,712 Gigabits of storage space in a single VHS tape filled with 16Gbit flash. Wow. What is that in GB?
    1,964 gigabytes

    Ok, so we'd need 10 of those for a 2-hour movie. But you have to remember, thats uncompressed. If we compress it, we just may get a single movie into a 1,964GB flassette (flash-cassette, something i just made up).

    Woot.

    HDTV isnt the future. A PC, Gnutella, and a HD2 projector is.

    Yep. There are too many layers in these TV specifications. What field are they in? Video or communications? There will be a need for ultra high res video in the future, but TV is dying.

    Every evening TV competes with /. for my time, and mostly loses. And I am not one of those who exhaust themselves on World of Warcraft until 3am then stagger into the office and pretend to work.

    The Broadcasting model came out of the basic physics of radio transmission. We are not limited by that anymore, so broadcasting is out.
