A new high-resolution television format has been approved by the UN's communication standards setting agency. The International Telecommunication Union (ITU) discussed the standard in May and offered broadcasters the opportunity to file objections. Because no-one did, it sent out letters confirming the format's approval.

Broadcasts in 8K will offer a resolution of 7,680 by 4,320 pixels - roughly the equivalent of a 32 megapixel photo. That is 16 times as sharp as current HD TVs offering about 2MP resolutions.

Japanese broadcaster NHK showed off the technology in London during the Olympics, where audiences said it gave them a sense of being at the events.

But it will be some time before such models become commercially available. One analyst says it could be more than a decade before the technology becomes affordable.

TV makers are currently focusing efforts on launching 4K enabled devices offering half the resolution. This is the format currently used by most digital cinema cameras.

But manufacturers are likely to want to offer 8K screens by 2020 when NHK aims to begin its first experimental broadcasts in the standard.
