Amazingly, in a research laboratory in Japan, the public broadcast service is secretly beavering away at new technology that will go beyond HD. NHK calls this (so far) Super Hi-Vision – it’s all very Japanese isn’t it!
The future is around 2025 apparently and it requires a screen size of 60 inches – which really limits how the average viewer will be looking at Super Hi-Vision. The usual math tells me that if it requires a screen that size then you should be sitting about 1.5x the diagonal viewing area. That’s some distance away!
Interestingly, a few varied uses for these screens with amazing clarity include showing off works of art and for use during concerts. The actual viewing area is made up of 7680 x 4320 pixels – sixteen times the number normally seen on a modern ‘HD’ screen.
Unfortunately, there are only two models of camera that shoot in such high resolution and they require 3.5 terabits of data just for 20 minutes of filming. This is fine for showing art but not much use for anything else. Nonetheless, another interesting development from the land of the rising sun…
