22.2 multichannel sound system

Super Hi-Vision's 22.2 channel 3D sound system soars far above the conventional 5.1 channel system.

We are researching and developing ways for people to enjoy the 22.2 multichannel sound experience in limited audio environments, such as those with fewer speakers, displays width built-in speakers, and headphones.

Technological developments

NHK develops technologies for all phases of the 8K Super Hi-Vision experience - from production equipment such as cameras and microphones, to broadcasting systems through which programs will be delivered.
