Album
Section of a music piece on a data CD
containing MP3 audio tracks or JPEG image
files.
Auto Pause
An automatical pauses according to the signal
encorded on the disc while playing a VIDEO
CD. If the CD player does not resume play for a
long time, press nN
manually.
Chapter
Subdivision of a title on a DVD. A title is
composed of several chapters.
Dolby Digital
This sound format for movie theatres 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-band width
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.
to resume play
• Dolby Pro Logic II Movie
The Movie mode is for use with stereo television
shows and all programes encoded in Dolby
Surround. The result is enhanced soundfield
directionality that approaches the quality of
discrete 5.1-channel sound.
• Dolby Pro Logic II Music
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 rear 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.
The picture data uses the MPEG 2 format, a
worldwide standards of digital compression
technology. The picture data is compressed to
about 1/40 of its original size. The DVD also
uses the 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.
File
Section of a picture on a data CD containing
JPEG image files.
