UDTV has been on the horizon for a while (that was 3840x2160). Now, the camera's the size of a shed and it goes with 22.2 channel sound and it's nominally 8k. BBC's been involved with NHK on this, and there will be some UDTV kit at the Olympics, but probably only one camera and display (you don't need more than one camera, because you can't pan the shot, the audience falls over, so a locked-off camera is just fine).

Get my test cards document, and cards for 625, 525, 720 and 1080. Thanks to Gavin Gration for hosting them.
Camera settings documents are held by Daniel Browning and at the EBU
My book, 'Circles of Confusion' is available here.
Also EBU Tech.3335 tells how to test cameras, and R.118 tells how to use the results.

What did you mean by "you can't pan the shot, the audience falls over", Alan?

When the display is really big, and I mean IMAX size, camera pans become a problem, because the display fills a large part of peripheral vision, you get the wrong clues about where the world is, and panning upsets equilibrium.

I get the same effect on the way home from the pub!;)

Aha! OK thanks.

A report on Click this week about the Super Hi-Vision tests with NHK said that the link bandwidth was 350MB/s. Although high by current standards of broadcasting, it seems that distributing images at this quality over LANs at major events and within institutions is viable.

Certainly viable, but expensive. The World Cup networks in SA (point-to-point) ran at 440MB/s, so getting networks running isn't the problem, it's in broadcasting and storage that the problems get to be difficult.
