Japan's NHK has started broadcasting the world's first 8K television content on a new 'Super Hi-Vision' satellite channel. NHK will air a mix of 4K and 7680 x 4320 8K content from 10AM to 5PM, with programming that includes concerts and highlights from the 2012 Olympics. There's just one problem – nobody actually owns an 8K TV, so NHK has set up six viewing stations in Japan as well as in Rio de Janeiro, and plans to air live footage from Opening and Closing Ceremonies at the Olympic Games kicking off this Friday.

NHK has had its eye on 8K broadcasts for years, hosting public viewing events as early as 2014. The company has used NAB in Las Vegas as a showcase for its latest innovations since 2006, highlighting its advances in high-resolution broadcasting in April of this year by using a 133MP 'portable 8K camera'.
