The BBC is to experiment with 4K broadcasting technology during the 2014 World Cup.

These tests will not be available to the public.

These tests are set to be the beginning of the BBC investigating how it can bring 4K to its viewers.

The BBC has previously been involved in testing 8K Ultra HD recordings of the 2012 Olympic Opening Ceremony.

Part of the trial will involve the BBC building its understanding of the limitations of sending 4K streams over the web, through iPlayer for example.

Sony is filming three games in 4K, including the World Cup Final itself. The footage is set to be put together into a film once the tournament is over.
