The BBC will show live 4K broadcasts of the Commonwealth Games this year in the host city of Glasgow.
If you want to see what all the fuss is about with 4K, head down to the Clyde Suite in the Glasgow Science Centre during the games (which start on 23 July) to catch the live broadcast.
4K is much sharper than high definition, with four times as many pixels.
The BBC will broadcast "certain elements" of the games between 10am and 5pm at the public showcase.
Other demonstrations will also take place, featuring partners and collaborators to be announced soon.
The BBC trialled 4K broadcasts during the World Cup, but didn't share them with the public.
The Commonwealth Games broadcast will be the first major live event to be produced and distributed entirely over Internet Protocol (IP) networks. The BBC will deliver it using a prototype version of what it hopes will become a new broadcasting system that takes advantage of the nippy speeds and ubiquity of internet networks and IT technology.
Matthew Postgate, controller, BBC R&D, said in a statement: "We may well look back at this trial as a watershed moment in the history of broadcasting. By proving for the first time that complex events can be created and delivered completely over IP technology, we're opening up a world of possibilities to programme makers and the wider industry.
"Not only could BBC R&D's vision for a new broadcasting system help producers create programmes more efficiently and cost-effectively, but it allows them to take advantage of data like never before, offering new editorial options and ways of improving the experience for audiences."
