In 5 years, will 8K be the 'Full HD' of today?

 

We may see that 4K ends up being the 720P of HD?

Quite a lot here at CES to see as far as 4K goes - including a demo of Samsung/Netflix demo of Netflix streaming 4K video to a Samsung TV. Will be a long time before there is any way of getting that in NZ however as it will only be available through specific ISPs who have a local cache.

Also saw the 8K prototype TV from Sharp. Incredible detail but up real close a top end smartphone still has a much higher definition (in terms of pixels per inch).

No doubt that as the production prices come down we'll probably see 4K becoming common place over the next 2-3 years. I'd think it's quite likely the next Xbox and PlayStation platforms will offer 4K (though depending on how soon we see them, maybe not in their initial release).

There are still several technical pieces that really need to be put into place on top of the content itself:
1. DVB broadcast standards don't support HEVC.
2, HDMI 1.4 doesn't support framerates of more than 24p with 4k (ie. I think 3D 4k is not possible with standard links).
3, Blu-ray standard doesn't support HEVC or resolution/frame rate greater than 1080p24.

My personal thoughts and predictions...

I estimate (2) and (3) are probably 6 to 12 months away, though reasonable gear prices are probably still 2 or even 3 years away. Who knows when (1) would happen... but I don't see it happening for broadcast TV in NZ for 5 years, if ever. DVB-T2 and DVB-S2 (or their successors) would almost certainly need to have taken hold, which would require many (the majority?) of [existing] STBs to be upgraded. Extra broadcast bandwidth is required as well of course. Depending on how the digital dividend auctions turn out, cellular upgrades to LTE[-A] may prevent terrestrial broadcast TV from acquiring the required bandwidth. On the satellite front, it is possible that extending the broadcast frequency range from 12.25..12.75 GHz to 11.7..12.75 GHz will help. My understanding is that the Optus D series satellites have this capability already. "Optus 10" may help as well, depending on where Optus puts/points it.

I'm happy to wait patiently. :)

There seems to be a lot of cunfusion with the use of 4k for consumer TV's and players. 4k is a pro standard and has a resolution of 4096x2160, while UHD (or QuadHD) has a resolution of 3840x2160. Sony, LG etc are confusing people when they refer to UHD as 4k, because it is not. Cinema 4k will still need to be down-sampled for any consumer devices/formats.
