I read on the BBC newslink to my mobile that a TV station in Japan has just started to broadcast in 8k definition although there are only a handful of people that can see it at the moment. It mentioned that they had done an 8k digital transfer of 2001:A Space Odyssey to demonstrate its superiority as they had done the transfer from a 70mm copy, and they also soon intend to do a 70mm transfer in 8k of My Fair Lady. Has anyone else heard about this?

Maybe Jason could comment ?

Just as an afterthought.... How many "k" would it need for definition to go beyond what is receptive to the human eye?

No-one seems to commit themselves on how many k it would need. I think there are too many variables. For a start only the main centre part (the yellow spot) of the eye is of high resolution do if the picture is very small it doesn't need many but a larger one you need much more even though only the part you were concentrating on would benefit.

The peripheral vision is more frequency conscious and changes register more then details I remember demonstrations of 100Hz refresh TV's had one in the centre of a bank of nine (the outer 8 being 50hz) which showed flicker. If they had been the other way round none would have. I don't think I made myself very popular when I pointed this out to the Philips rep at the exhibition.

I just heard the news here in Japan a few days ago. NHK, the national broadcaster will start broadcasting in 8K but you will need to spend a lot to receive the broadcasts. NHK broadcasts Over the air and offers satellite broadcasts which require a special NHK sateliitte antenna. Just about every home in here has a dedicated satelitte dish to receive NHK broadcasts but will need new satelitte dished capable of receiving 8k broadcasts.

I heard that you would need a special tuner to receive the NHK satelitte broadcast. I believe that most 8k tvs now should have a tuner built in. Here is a link to a 8k tuner for sell on Amazon Japan. It will set you back more than 8,000 USD.

NHK will be broadcasting the Olympics in 8K here in Japan. So all of this is in preparation for August 2020. I have seen 8k content at a NHK office here and the image quality is amazing. You have to see it to believe it.

They broadcast 2001 A Space Oddessy in 8K this past Saturday here in Japan.

IMHO the transition from 4K(or even FHD in several areas) to 8K would have much,much less impact than SD>>>HD transition. Since we'd need that large display to realize its potential,which would be impractical/too much for home use. [Roll Eyes]
(Do we really absolutely need that wall-sizedTV screen?)

But for cinema use...that's another story. [Wink]

I project on a six foot wide screen with a 1080p projector. I'm a big fan of 2001 and I have the DVD and Blu Ray of the film. The DVD looks great but the BD is better in respect of definition and 'naturalness' but has anyone else noticed that the Blu Ray disc reveals a bit too much. You can see the texture of the backdrop in the 'apes' prologue which I believe was front projection. I'm guessing that an 8k transfer would reveal even more shortcomings...
