It's an issue that's kept us all awake at night: just what should we call the new mega high-definition TV standards? Well now we have an answer...
The International Telecommunications Union (ITU) has agreed that the new standard for high-definition transmissions will be called UHDTV, or Ultra High Definition Television.
"This is the dawn of a new age for television that will bring unprecedented levels of realism and viewer enjoyment. It's a historic moment," said David Wood, Chairman of ITU-R Working Party 6C.
"Some years will pass before we see these systems in our homes, but come they will. The die is now cast, thanks to the untiring efforts of the international experts participating in WP6C."
Hurrah! No longer will there be confusion, you may be thinking, but not so fast. While the standard has a name, the numbers behind the standard seem surprising, as both 4K and 8K TV will be covered by the same umbrella UHDTV name. When the resolution of 8K (7,680 x 4,320 - 32megapixels) is four times that of 4K (3,840 x 2,160 - 8megapixels), it seems odd not to differentiate them, even if there's an argument for saying they're both 'high enough'.
Then again, this is currently only a recommendation so we could well see these names become more granular.
The first consumer grade TV to offer 4K resolution is the Toshiba 55ZL2 glasses-free 3D TV (pictured), while the first projector is the Sony VPL-VW1000ES. Costing £6,999 and £16,799 respectively, they're a strong indicator that it may be some time before the majority of us have to care too much about exactly what 4K is called, let alone give two hoots about 8K.
Invested in the 4K revolution yet or is HD still enough for you? Let us know your thoughts in the comments.
