This configuration is known as 5.1, with the “.1” referring to the
LFE source (also known as a subwoofer). Dolby Surround Digital
is the home video version, available on digital video discs (DVDs).
A competing system called DTS (Digital Theater Systems),
introduced with Jurassic Park, also uses the 5.1 configuration.
Circle Surround analog decoding system also supports 5.1.
IMAX uses a 6.1 system, adding a top channel to the 5.1 standard.
This configuration was supported by the original Holophone H-1
(now discontinued).
Dolby, DTS and SRS Labs (among others) introduced extended
surround formats that use a 6.1 configuration. These are Dolby
