22.2 surround sound

Short description: Surround sound component of Super Hi-Vision

22.2 or Hamasaki 22.2 (named after Kimio Hamasaki, a senior research engineer at NHK Science & Technology Research Laboratories in Japan) is the surround sound component of Super Hi-Vision (a new television standard with 16 times the pixel resolution (7680×4320) of HDTV (1920x1080). It has been developed by NHK Science & Technical Research Laboratories. It uses 24 speakers (including two subwoofers) arranged in three layers.[1]

## Channels

Diagram of three major multichannel audio formats: 5.1, 9.2 and 22.2 channel layouts.

The channel numbers and labels are:[2] {| class="wikitable" |- ! AES
Pair No./Ch No. ! Channel
No. ! Label ! Name |- | 1/1 | 1 | FL | Front left |- | 1/2 | 2 | FR | Front right |- | 2/1 | 3 | FC | Front center |- | 2/2 | 4 | LFE1 | LFE-1 |- | 3/1 | 5 | BL | Back left |- | 3/2 | 6 | BR | Back right |- | 4/1 | 7 | FLc | Front left center |- | 4/2 | 8 | FRc | Front right center |- | 5/1 | 9 | BC | Back center |- | 5/2 | 10 | LFE2 | LFE-2 |- | 6/1 | 11 | SiL | Side left |- | 6/2 | 12 | SiR | Side right |- | 7/1 | 13 | TpFL | Top front left |- | 7/2 | 14 | TpFR | Top front right |- | 8/1 | 15 | TpFC | Top front center |- | 8/2 | 16 | TpC | Top center |- | 9/1 | 17 | TpBL | Top back left |- | 9/2 | 18 | TpBR | Top back right |- | 10/1 | 19 | TpSiL | Top side left |- | 10/2 | 20 | TpSiR | Top side right |- | 11/1 | 21 | TpBC | Top back center |- | 11/2 | 22 | BtFC | Bottom front center |- | 12/1 | 23 | BtFL | Bottom front left |- | 12/2 | 24 | BtFR | Bottom front right |} Channel numbers up to 6 represent the same as those in a 5.1 channel system. There are then a further 5 listener-plane channels, 9 overhead channels, arranged in a square, and a row of 3 further channels at the bottom front, plus the additional LFE channel.
