Glossary

Album
Section of a music piece or an image on a
data CD containing MP3 audio tracks.
Chapter
Sections of a picture or a music piece on a
DVD that are smaller than titles. A title is
composed of several chapters.
Dolby Digital
This sound format for movie theaters is
more advanced than Dolby Pro Logic
Surround. In this format, the surround
speakers output stereo sound with an
expanded frequency range and a sub woofer
channel for deep bass is independently
provided. This format is also called "5.1"
because the sub woofer channel is counted
as 0.1 channel (since it functions only when
a deep bass effect is needed). All six
channels in this format are recorded
separately to realize superior channel
separation. Furthermore, since all the signals
are processed digitally, less signal
degradation occurs.
Dolby Pro Logic Surround
As one method of decoding Dolby Surround,
Dolby Pro Logic Surround produces four
channels from two-channel sound. Compared
with the former Dolby Surround system,
Dolby Pro Logic Surround reproduces left-to-
right panning more naturally and localizes
sounds more precisely.
To take full advantage of Dolby Pro Logic
Surround, you should have one pair of
surround speakers and a center speaker. The
surround speakers output monaural sound.
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
soundfield 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.
DTS
Digital audio compression technology that
the Digital Theater Systems, Inc. developed.
This technology conforms to 5.1-channel
surround. The surround channel is stereo
and there is discrete sub woofer channel in
this format. DTS provides the same 5.1
discrete channels of high quality digital
audio. The good channel separation is
realized because the all channel data is
recorded discrete and processed in digital.
DVD
A disc that contains up to 8 hours of moving
pictures even though its diameter is the same
as a CD.
The data capacity of a single-layer and
single-sided DVD, at 4.7 GB (Giga Byte), is
7 times that of a CD. Furthermore, the data
capacity of a dual-layer and single-sided
DVD is 8.5 GB, a single-layer and double-
sided DVD 9.4 GB, and a dual-layer and
double-sided DVD 17 GB.
