Digital Cinema Sound (DCS)
This is the generic name of the surround sound
produced by digital signal processing
technology developed by Sony. Unlike previous
surround sound fields mainly directed at the
reproduction of music, Digital Cinema Sound is
designed specifically for the enjoyment of
movies.
Dolby Digital
This movie theater sound format is more
advanced than Dolby Surround Pro Logic. In
this format, the surround speakers output stereo
sound with an expanded frequency range, and a
subwoofer channel for deep bass is
independently provided. This format is also
called “5.1,” with the subwoofer channel
designated as the 0.1 channel (since it functions
only when a deep bass effect is needed). All six
channels in this format are recorded separately
for superior channel separation. Furthermore,
since all the signals are processed digitally, less
signal degradation occurs.
Dolby Digital EX
An enhanced compatible format of Dolby
Digital 5.1, developed by Dolby Laboratories
and Lucasfilm THX, which adds an extra
surround back channel, and can be used for
6.1(three surround speakers) channel playback,
using matrix encoding.
Dolby Pro Logic II
Dolby Pro Logic II creates five full-bandwidth
output channels from two-channel sources. This
is done using an advanced, high-purity matrix
surround decoder that extracts the spatial
properties of the original recording without
adding any new sounds or tonal colorations.

Movie mode
The Movie mode is for use with stereo television
shows and all programs encoded in Dolby
Surround. The result is enhanced sound field
directionality that approaches the quality of
discrete 5.1-channel sound.
x
Music mode
The Music mode is for use with any stereo music
recordings, and provides a wide and deep sound
space.
Dolby Surround Pro Logic
As one method of decoding Dolby Surround,
Dolby Surround Pro Logic produces four
channels from two-channel sound. Compared
with the former Dolby Surround system, Dolby
Surround Pro Logic reproduces left-to-right
panning more naturally and localizes sounds
more precisely. To take full advantage of Dolby
Surround Pro Logic, you should have one pair of
surround speakers and a center speaker. The
surround speakers output monaural sound.
DTS
Digital audio compression technology
developed by Digital Theater Systems, Inc. This
technology conforms to 5.1-channel surround.
This format comprises of stereo rear channels
and a discrete subwoofer channel. DTS provides
the same 5.1 discrete channels of high quality
digital audio. The good channel separation is
realized due to all channel data being recorded
discretely and processed digitally.
DTS-ES
An enhanced compatible format of 5.1 channel,
which adds an extra surround back channel.
There are two formats: Discrete 6.1, which
processes the surround back signal
independently, and Matrix 6.1, which processes
it along with the Surround (L/R) channels.
