World’s first 8K TV broadcasts begin for Rio 2016 Olympics
The world's first broadcast using 8K TV technology has begun on Japan's public channel NHK. With a resolution of 7680i-4320, "Super Hi-Vision" as the company calls it-don't worry, the name won't catch on-has about four times the detail of a 4K broadcast, or 16 times what you're probably watching at home (normal HD, 1920i-1080).
The 8K broadcast will be tested over the next five days, and from August 6 it will be used to broadcast parts of the Rio 2016 Olympic Games, which are being filmed in 8K by special NHK cameras.
This shows you the relative resolution of 8K vs. 4K and HD.
Of course, viewing an 8K broadcast will be rather difficult even in Japan, as none of the equipment required to receive and display the 8K signal has yet been commercially released. Instead, NHK has set up two special 8K viewing theatres in Tokyo and Osaka for the duration of the trial. For really determined home users, Sharp apparently sells an 85-inch 8K TV for about 120,000, but I couldn't find it in stock anywhere.
