Some of the Rio 2016 Olympic Games will be covered in 8K ‘Super Hi-Vision’ (for Japan), and there will be 4K Ultra HD versions created for testing and comparison purposes. The 8K versions for Japan will include ‘immersive’ audio using what Olympic Broadcasting Services (OBS) describe as “3D 22.2 channel audio surround sound”.
