8k channel launched today

[Channel Hopper]

BS8K, part of NHK (Japan)

Space Odyssey to launch first 8K TV channel

 

[stonesatellite]

how is it the first 8K channel or does it mean full time channel (ie not a test/loop channel) ?

 

[Channel Hopper]

10 hours planned per day.

Do you know of another service out there ?

aye as Analoguesat said Turksat 8K

How big a screen do you need to see the difference between 4K and 8K?

That was a demo channel for the Globalsat trade show (Istanbul) last month that has spilled over, much like the demos on display at the last IBC show at RAI. There is no dedicated programming from a broadcaster, the Super High-Vision content from Japan includes sponsored content from screen manufaturer, Sharp.

OB vehicles toured Europe including the UK, visiting Kew Gardens five weeks ago to install a SHV studio in Cambridge Cottage for the week, recording content in both 4 and 8K.

hence why i asked, havent seen Turksat 8K first hand so wasnt sure if it was a test or full channel

Samsung have an 8k screen for sale in the UK now. I wasn't impressed. Only showing the usual demo content, vibrant color slow-mo. 8k might look nice on a 150" screen

The cost of producing then broadcasting a programme in 8K means it will be a few years yet before anything is out on the market. NHK has a huge task to get their channel beyond the promotional side of broadcasting, hence the dual standard of 4K just to get the content out there.

2001 would still look superb in the lower standard regardless.

I remember a story regarding NHK and its early development of UHD where they had started at first on resolutions for what would be regarded as 8K back in the mid 00's. Because of the sheer resolution size, nearly all equipment were prototypes that were often modified from what was available at the time, requiring hard drives that could handle large read/write speeds with large capacities to match (AVC/H.264 was only starting to find its feet). So with a specially adapted camera that could record 7680x4320 video (16 times the pixel of that for 1080i/p) set up on a car they drove about Tokyo to capture some sample video at this resolution. When they finished doing some editing they did a first in house demonstration to other NHK employees by using a projector (again a prototype) that could display the recorded resolution on a wall, I think the effective display size was 110 inches but I'm not fully sure. Anyway this first demonstration left a number of viewers ending up with motion sickness albeit brought on from the reverse of what is normally the case - those watching the drive around Tokyo video had their brain thinking they were moving while their body sensed it was stationary, while usually getting motor sickness in a vehicle comes from the opposite way round!

When I read about that the first time, that story convinced me that it had to be good, and surely there was little point trying to go beyond that except for some very specialised cases - well it seems that NHK is already working on development for 16K resolution!

16K resolution - Wikipedia

 

[Channel Hopper]

The answer is - partly - within the text of the link.

Today's technology, the 'VR' goggles will require something like the resolution that 16K offers, for fully immersive experiences. The goal doesn't stop there however.

Once you can capture and transmit a stable six million pixels per second electronically there is really no reason why the output has to be delivered to the eye using a set of goggles, there will be a requirement to send moving images directly via the optic nerves, removing the most common item that affects the majority of humans, physical differences (genetic or injury ) of the eyeball structure. With the exception of some experimental surgery and replacement, the best medicine has to offer currently is lens shaping or corneal replacement, with very little improvement for the foreseeable (sic) future.

The increase in delivery speed, however goes beyond immersive VR since the electronics at the front end don't actually stop at the - human- visible spectrum limits. If the camera can detect other wavelengths, there comes with it the ability to shift, or increase the current bandwidth so that the recipient gets to 'observe' realms of detail that currently only some other animals have access to without specialist detection equipment.

With the increase in bandwidth also comes the ability to play with the time base. Correctly delivered, the user will be able to have content received at higher than normal speeds. There is no reason why the brain once trained, cannot accept a revised input of information delivered for example at twice the rate, commencing with two independent streams of data, one into each optic channel, then moving onto a full departure of the normal timeline.

Uploader says its an upscale from 1080p.

Just a copy of the original maybe then ?
I think 8K is only for Cinema big screens & conference halls,
4K is just fine for my small 50 inch screen.

 

[Channel Hopper]

You will not find much film content on Youtube that is truly above 4k resolution, yet.

Gameplay however is getting there sooner.

Anyone picked up a signal yet in Eutelsat 12 West A?

 

[popovp]

NHK transmits Vatican 8K images via Eutelsat

 

[Analoguesat]

Can you watch 4k youtube on a 4 meg connection??? Nope...... It looks nice between the whirling buffering circles though!

 

[Channel Hopper]

Anyone picked up a signal yet in Eutelsat 12 West A?

It is currently in two places according to the usual suspects

FlySat Eutelsat 59A

Eutelsat 59A at 54.0°E - LyngSat

Neither show signal.
