encoded as 2/4.0, 2/4.1, 3/4.0, or 3/4.1.
N Blu-Ray DVD players are designed to output audio from Blu-Ray DVDs,
which can carry 7.1 or more discrete encoded channels. However, that audio can
only be transmitted via the HDMI output and can only be processed by an AV
receiver that supports HDMI connections. The Blu-Ray player should support
S/PDIF connection that will output Dolby Digital and DTS multi-channel
source formats, which are also embedded in the Blu-Ray DVD and can be used
to feed into the SSP 7.1 via TosLink or coaxial connection.

Dolby Digital is a flexible, discrete, digital technology for carrying audio. Dolby
Digital is a 5.1-channel surround sound format and is the standard for DVD video.
Dolby Digital features up to five discrete, channels (front center, front left, front
right, surround left, and surround right), which gives it the "5" designation. Each
of the channels is full frequency with respect to human hearing (20 Hz to 20k
Hz). There is an additional channel reserved for low frequency effects (LFE),
which is usually reserved for the subwoofer speaker(s) or other speakers capable
of reproducing low frequency ranges (3 - 120 Hz). This gives the ".1" designation,
since the sixth channel is not full frequency.
Although referred to as 5.1, it includes a variety of combinations, including 1.0, 2.0,
2.1, 3.0, 3.1, 4.0, 4.1, 5.0, and 5.1.

is used, typically, for digital television broadcast signals and older, remastered,
movies.
