Album
Section of a music or picture piece on a DATA
CD or DATA DVD containing MP3 audio
tracks or JPEG image files.
Chapter
Subdivision of a title on a DVD VIDEO. A title
is composed of several chapters.
Dolby Digital
This sound format for movie theaters 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” because the subwoofer 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.
Futhermore, since all the signals are processed
digitally, less signal degradation occurs.
Dolby Pro Logic II
This technology converts 2 channel stereo
recorded audio into 5.1 channels for playback.
There is a MOVIE mode for movies and MUSIC
mode for stereo sources such as music. Old
movies encoded in traditional stereo format can
be enhanced with 5.1 channel surround sound.
Movie mode
The Movie mode is for use with stereo television
shows and all the programmes 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
As one method of Dolby Surround decoding,
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 advantages 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 that the
Digital Theater Systems, Inc. developed. This
technology conforms to 5.1-channel surround.
The surround channel is stereo and there is
discrete subwoofer 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 VIDEO
A disc that contains up to 8 hours of moving
pictures even though its diameter is the same as
a AUDIO CD.
The data capacity of a single-layer and single-
sided DVD VIDEO, at 4.7 GB (Giga Byte), is
7 times that of a AUDIO CD. Furthermore, the
data capacity of a dual-layer and single-sided
DVD VIDEO is 8.5 GB, a single-layer and
double-sided DVD VIDEO 9.4 GB, and a dual-
layer and double-sided DVD VIDEO 17 GB.
The picture data uses the MPEG 2 format, one of
the worldwide standards for digital compression
technology. The picture data is compressed to
about 1/40 of its original size. The DVD VIDEO
also uses variable rate coding technology that
changes the data to be allocated according to the
status of the picture.
The audio data is recorded in Dolby Digital as
well as in PCM, allowing you to enjoy more
realistic audio presence.
Furthermore, various advanced functions such
as the multi-angle, multilingual, and Parental
Control functions are provided with the DVD
VIDEO.
