Video technology can only get better and it seems we have only started to witness the evolution of high definition TV. Called Super Hi-Vision (and often known as 8K4K or Ultra HD), a new system has been developed by Japan’s national broadcaster, NHK, and the same engineers who worked on the original Hi-Vision tech in the 1980s.
NHK’s Super Hi-Vision Ultra high-definition TV system – to give its full name – is built around images with a 7,680 x 4,320 pixel resolution, equating to roughly 33 megapixels. The current pinnacle of hi-def, Full HD, measures just over two megapixels.
The question is how long it will be before 8K4k becomes a domestic reality. The answer is 15 years at least. And maybe never in the UK.
