Ultra HD for Olympics

[Michael Panfeld]

So, I just got an invitation to view part of the Olympics in Ultra HD. It is co-sponsored by Comcast and NBC-Universal. I assume this is the same as Quad TV, which is a bit off of 4K. Does anybody know which camear platform and workflows might be involved? Is it an EPIC, or something else on the acquisition side? A projector or some prototype flat screen on the viewing side?

Its NHK (by Twinscam), A new camera developed by Japanese public broadcaster.

 

[Subhadip Sen]

As far as I know, acquisition will be NHK cameras, 7680 x 4320 at 60 fps.

 

[Patrick Grossien]

UHD should be more like 8K.

Workflow? I believe it's live.

 

[Jay Birch]

Yep, it's 8K live

 

[Petr Dvorak]

8K ...

As far as I know, acquisition will be NHK cameras, 7680 x 4320 at 60 fps.

I thought they were targeting 120 fps for Super Hi-Vision.

 

[Sulekh Suman]

I like where this is going

DAMN... how are they debayering all that rez in real-time ?? Or is the NHK's format output-ready for live broadcast?

 

[Phil Holland]

I believe it's scaled down on the camera on the output, however, it is very large. Think a couple tool boxes.

Worth checking out, if you're in the UK

"There are three public viewing theaters in the UK: BBC Broadcasting House in London; BBC Pacific Quay in Glasgow; and National Media Museum in Bradford."

What i'd like to know is how they're compressing 8K and broadcasting it to 3 locations and at what rate they're sending it on Japan in.

 

[Chris Foreman]

As far as I know they are using H264 encoders and it's being compressed from 24Gb/s to 280Mb/s. The Data streams to the theaters are 350Mb/s. I've seen the demo and I have to say it's impressive...most impressive. It's come a long way from the test material I saw a few years ago.

The first thing that hits you is that it's not like typical TV coverage, the shots are all quite wide, which is a bit odd and I feel it could do with a few closer shots especially having seen the normal TV coverage of the opening. Then when you reaslise that this is a completely different experience you can sit back, relax and take it all in. The screen I saw it on was 300" and I was only sitting about 15" from it (3 rows back). The sound is astounding, the whole experience is akin to IMAX. At one point I had to stop myself getting up and cheering during the swimming coverage. It gave me goosebumps more than once. It is the closet thing to actually being there, when they can get weather in there as well :emote_rainshower:it'll tick all the boxes.

If you want a bit more of the detail...

Get to see this if you can, it'll change the way you look at TV sport forever.

This is a very good question.
