The purpose of 8K is not to make us jealous of Japan (again); in fact there's only one consumer 8K TV available, Sharp's LV-85001. Rather, the nation intends to broadcast its 2020 Tokyo Olympics in Super Hi-vision, so it's using the Rio event as a trial run. OBS will also be testing 4K downscaling, high dynamic range and hi-color gamuts as well; by 2020, a lot more folks will have access to those features. However, it won't air any 4K footage for Rio; instead the games will be broadcast in 1080p video with 5.1 surround sound around the world. All told, there will be 7,000 hours of coverage broadcast to 220 countries and more than 5 billion viewers.
