Glossary

Chapter (page 9)
Sections of a picture or a music feature that
are smaller than titles. A title is composed of
several chapters. Depending on the disc, no
chapters may be recorded.
Dolby Digital (page 24, 63)
Digital audio compression technology
developed by Dolby Laboratories. This
technology conforms to 5.1-channel
surround sound. The rear channel is stereo
and there is a discrete subwoofer channel in
this format. Dolby Digital provides the same
5.1 discrete channels of high quality digital
audio found in Dolby Digital cinema audio
systems. Good channel separation is realized
because all of the channel data are recorded
discretely and little deterioration is realized
because all channel data processing is
digital.
Dolby Surround (Pro Logic) (page 23)
Audio signal processing technology that
Dolby Laboratories developed for surround
sound. When the input signal contains a
surround component, the Pro Logic process
outputs the front, centre and rear signals.
The rear channel is monaural.
DTS (page 24, 64)
Digital audio compression technology that
Digital Theater Systems, Inc. developed.
This technology conforms to 5.1-channel
surround sound. The rear channel is stereo
and there is a discrete subwoofer channel in
this format. DTS provides the same 5.1
discrete channels of high quality digital
audio.
Good channel separation is realized because
all of the channel data is recorded discretely
and little deterioration is realized because all
channel data processing is digital.
DVD (page 6)
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 is 4.7 GB (Giga Byte),
which is 7 times that of a CD. The data
capacity of a double-layer and single-sided
DVD is 8.5 GB, a single-layer and double-
68
sided DVD is 9.4 GB, and double-layer and
double-sided DVD is 17GB.
The picture data uses the MPEG 2 format,
one of the worldwide standards of digital
compression technology. The picture data is
compressed to about 1/40 (average) of its
original size. The DVD also uses a variable
rate coding technology that changes the data
to be allocated according to the status of the
picture. Audio information is recorded in a
multi-channel format, such as Dolby Digital,
allowing you to enjoy a more real audio
presence.
Furthermore, various advanced functions
such as the multi-angle, multilingual, and
Parental Control functions are provided with
the DVD.
Index (CD)/Video Index (VIDEO CD) (page
9)
A number that divides a track into sections
to easily locate the point you want on a CD
or VIDEO CD. Depending on the disc, no
index may be recorded.
MPEG audio (page 24, 63)
International standard coding system used to
compress audio digital signals authorized by
ISO/IEC. MPEG 1 conforms to up to 2-
channel stereo. MPEG 2, used on DVDs,
conforms to up to 7.1-channel surround.
Scene (page 9)
On a VIDEO CD with PBC (playback
control) functions, the menu screens, moving
pictures and still pictures are divided into
sections called "scenes."
Title (page 9)
The longest section of a picture or music
feature on a DVD, movie, etc., in video
software, or the entire album in audio
software.
Track (page 9)
Sections of a picture or a music feature on a
CD or VIDEO CD (the length of a song).
