22.2 multichannel sound system

UHDTV'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 with built-in speakers, and headphones.
