Japan Successfully Broadcasts 8K Signal Over The Air

We assumed the gorgeous 8K ultra-HDTVs we saw at CES this year were years away. But Japan's NHK has just completed the first over-the-air broadcast of a 7680x4320 signal using UHF frequencies — just when you'd finished paying off your giant HDTV display.

The compressed Super Hi-Vision signal, as the NHK calls it, was broadcast over a distance of about 4km without any errors on the receiving end. So it's not like the broadcaster has started blanketing Tokyo in a glorious 8K signal just yet, but it's an important milestone. And to facilitate all that data, 16 times the resolution of a 1920x1080 HD image, the researchers spread the signal across a couple of UHF frequencies. Which means that one day the government might have to rustle up even more spectrum space if 8K ends up replacing our recently deployed hi-def networks. [NHK via AV Watch via Engadget HD]

    If Australia had a national fibre optic cable network in place then we wouldn't need to hassle with wireless spectrum for 8K TV as the signal could be squirted down the cables.

      At a cost of $199.99 per month with a viewing cap of only 10 hours peak / 10 hours off-peak. After the viewing cap has been reached, your connection will be reduced to standard 480p until the beginning of the next viewing cycle.

      FTFY.

        This is the scenario the NBN was designed to prevent, FYI.
        My opinion is that it WILL be prevented if the NBN is successfully rolled out.

        heh true, though a broadcast (or multi cast) through a wired network should still be more efficient than individually sending the same thing to millions of users. assuming the infrastructure could handle the functionality

    I could definetly see 8K running through the NBN pipes in the future. You have to remember that optical fibre has the capability of transferring data at the speed of light :)

    Soon Fry will be right...
