Glossary
DCS (page 19)
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 (page 18)
Digital audio compression technology developed
by Dolby Laboratories. This technology conforms
to multi-channel surround sound. The rear channel
is stereo and there is a discrete subwoofer channel
in this format. Dolby Digital provides the same
discrete channels of high quality digital audio
found in “Dolby Digital” theatre surround sound
systems.
Good channel separation is realized because all of
the channel data is recorded discretely, and little
deterioration occurs because all channel data
processing is digital.
Dolby Pro Logic II (page 18)
Dolby Pro Logic II creates five full-bandwidth
output channels from 2 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.
◆
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 (page 18)
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 centre speaker. The surround speakers output
monaural sound.
DTS
Digital audio compression technology by Digital
Theater Systems, Inc. This technology conforms
to multi-channel surround sound. The rear channel
is stereo and there is a discrete subwoofer channel
in this format. DTS provides the same discrete
channels of high quality digital audio.
Good channel separation is realized because all of
the channel data is recorded discretely, and little
deterioration occurs because all channel data
processing is digital.
