Surround Channel Information

Surround channel information is written in the following format:
A/B.C (For example 3/2.1)
A represents the number of front channels (maximum 3: front right, front left, and center).
If A is 1, the source format has a mono encoded signal for playback through the center
channel. If A is 2, the source format encodes two discrete channels for stereo playback
through the front right and front left channels. If A is 3, there is a discrete encoded signal for
all three front speakers.
B represents the number of surround channels (maximum 3: surround right, surround left,
and back). If B is 1, the source format has a mono encoded signal for playback as dual mono
through the surround right and surround left channels. If B is 2, the source format encodes
two discrete channels for stereo playback through the surround right and surround left
channels. If B is 3, there is a discrete encoded signal for all three speakers, including the back
speaker.
NOTE: There is no "4" option because, while the SSP 7.1 can output up to eight full
C represents the presence or absence of LFE (1 = present; 0 = none or absent). This is the
discrete bass information, normally designated for use with the subwoofer channel, but may
be mixed with other channels in the absence of a subwoofer.
bandwidth channels, there are presently no source formats that can pass digital
bit stream audio information containing 7.1 discrete encoded channels through
S/PDIF connections, which is the connection type that the SSP 7.1 supports.
