"Ultra HD Signal; 16 Times Better Than HDTV"

Hello! Can you imagine the media that this would need to store an entire movie?

"To help ease that burden, NHK is enlisting the help of ATEME, a provider of MPEG-4 and H.264 solutions, to compress the 7680 x 4320 "Ultra HD" video – creating a new video standard."

Can you imagine the amount of compression needed to make this even manageable for a storage medium?

Holographic Versatile Discs currently hold 3.9 TB - which according to the above stats equals 20 minutes of uncompressed Ultra HD. Even at 22.2, the UberHD Sound is going to be an insignificant increase in storage required.
With only a 2:1 compression that's 40 minutes already. Also, I suspect that with the very high pixel count (i.e., smaller changes in shading/color between two adjacent pixels) the compression algorithms are going to be even more efficient. Now, bandwidth is going to be another story. For three colors that's going to be pretty hefty - but certainly not a huge worry compared to making 8000X4000 pixels affordable! That has to be at least 16x what a 2000x1000 panel costs now in the best case scenario, but it's going to be a lot more, of course.
And forget cable/sat broadcasts for the forseeable future.
