Future Ultra HD TV will be 8K, not just 4K
Just as we start to see the arrival of 4K TVs, delivering four times the resolution of current HD TVs, it's been announced that the future standard for Ultra High Definition TV will deliver even greater definition than the new sets can handle.
And if all goes according to plan, we could have broadcasts – and TVs – capable of 7680x4320-pixel resolution, 16 times that of today's Full HD TVs, as soon as 2020.
Japanese broadcaster NHK has announced that its Super Hi-Vision – or SHV – system has been approved as an international standard for future ultra-high-definition TVs by the global broadcast standards body, the International Telecommunication Union.
And not only will the new standard have that super-high resolution, it's also planned to have a much wider colour gamut – bringing it closer to the full range of colours the human eye can see – and double the frame-rate of current SHV to 120fps for smoother motion-rendering.
There are even plans for extended sound systems, using as many as 22.2 channels of sound for a fully immersive experience.
However, the adoption of that will be part of an extension of the standard, which will also cover small matters such as how the 8K signal will be handled by the broadcast chain, which will require extremely high-speed compression.
There are also technical issues when it comes to storing and shooting the new content: it requires huge amounts of storage, and the cameras currently used are both large and limited in their portability, not to mention having viewfinders allowing their users to see only a tiny fraction of the resolution being recorded.
The Super Hi-Vision system was trialled during the London 2012 Olympics by a team from NHK working with the BBC and supported by broadcast experts SIS Live, which operates the UK's largest fleet of outside broadcast and satellite uplink vehicles.
The NHK team brought from Japan not only a specially adapted broadcast truck, but also three 8K cameras – actually the only three 8K cameras in the world.
These cameras were connected to the NHK truck, while the 22.2 channel sound was mixed using NHK audio equipment integrated into a truck provided by SIS Live, and the content sent to the Super Hi-Vision production centre using 24Gb/s links over optical fibre.
Previewing used an 85in prototype screen, and then the content was recorded for transmission and backup. Showing of the 8K coverage, including the opening and closing ceremonies and the Men's 100m final, were held in London, Glasgow and Bradford, as well as in the USA and Japan.
The viewings used 250in or 300in screens, and full 22.2-channel sound systems, but the ITU standard is for broadcast into the home as well as for public events such as this.

Bit of a shame, i don’t think i can get planning permission for an extension that big, it may encroach on next doors property, also may get a few sound complaints.
All sounds fine if you have £100k + to spend & then the room needed for a 22.2 sound system...Marketing has become totally ridiculous for the average person,of course seeing something like this makes buying that new kit easier to swallow,as all we will need is a new 4k tv &/or projector,super hd bluray player & if course a new avr with new codecs that todays 4k passthrough units simply wont have.So these 3 or 4 components will ONLY cost 5 or 6k if all goes to plan, Honestly,how many people are going to have the money or space for a SHV system in 2020,its not a million miles away...
I watched highlights from the Olympics at the International Broadcast Centre in the Olympic Park on this system. And it is staggering - both in the quality of the picture and the 22.2 sound. Truly like being there.
