If you thought 4K picture quality was sharp, you want to get yourself to Japan. There, public broadcaster NHK has started broadcasting in eye-popping 8K, just in time for the Olympics.
4K picture quality has four times as many pixels as high definition, making for a much sharper image. Then 8K is four times as sharp as that, which is so sharp it's difficult to imagine.
8K broadcasts have a resolution of 7,680x4,320 pixels. Basically, it'll make hi-def look like VHS.
To put it in perspective, we're only just getting 4K broadcasts here in the UK. BT Sport Ultra HD broadcasts in 4K, and Sky will launch its 4K service next weekend to coincide with the start of the Premier League season. But that's about it in terms of broadcasts you can watch.
The BBC has trialled the technology, and services like Netflix offer select films and TV shows in 4K, too. But at the moment, there are too few 4K-compatible TVs in homes to make it a mainstream technology.
The NHK 8K channel will air from 10am to 5pm daily, with extended hours during the Olympics. That's right, you could be watching Usain Bolt in 8K.
The tech has been long in the pipeline – NHK has been working on it for two decades, in fact. But this is par for the course for the broadcaster. After all, it started high definition broadcasts way back in 1989.
At the moment, the 8K broadcast won't reach homes, so eager viewers will have to head down to one of NHK's public viewing areas around Japan. It hopes to broadcast 8K to homes by 2018.
