Glossary
Analog:
Sound that has not been turned into num-
bers. Analog sound varies, while digital sound has
specific numerical values. These jacks send audio
through two channels, the left and right.
Aspect ratio:
The ratio of vertical and horizontal
sizes of a displayed image. The horizontal vs. vertical
ratio of conventional TVs. is 4:3, and that of wide-
screens is 16:9.
AUDIO OUT Jacks:
Jacks on the back of the
DVD System that send audio to another system (TV,
Stereo, etc.).
Bit Rate:
The amount of data used to hold a given
length of music; measured in kilobits per seconds, or
kbps. Or, the speed at which you record. Generally,
the higher the bit rate, or the higher the recording
speed, the better the sound quality. However, higher
bit rates use more space on a Disc.
Chapter:
Sections of a picture or a music piece on
a DVD that are smaller than titles. A title is com-
posed of several chapters. Each chapter is assigned a
chapter number enabling you to locate the chapter
you want.
Component Video Out Jacks:
Jacks on the back
of the DVD System that send high-quality video to a
TV that has Component Video In jacks (R/G/B, Y/Pb/
Pr, etc.).
Disc menu:
A screen display prepared for allowing
selection of images, sounds, subtitles, multi-angles,
etc. recorded on a DVD.
Digital:
Sound that has been converted into
numerical values. Digital sound is available when you
use the DIGITAL AUDIO OUT COAXIAL or OPTI-
CAL jacks. These jacks send audio through multiple
channels, instead of just two channels as analog
does.
DivX 3.11/4x/5x:
The DivX code is a patent pend-
ing, MPEG-4 based video compression technology,
developed by DivXNetworks, Inc., that can shrink
digital video to sizes small enough to be transported
over the internet, while maintaining high visual qual-
ity.
Dolby Digital:

oped by Dolby Laboratories containing up to six
channels of digital audio (front left and right, sur-
round left and right, center and subwoofer).

The formats were developed by different companies.
JPEG:
A very common digital still picture format. A
still-picture data compression system proposed by
the Joint Photographic Expert Group, which fea-
tures small decrease in image quality in spite of its
high compression ratio.
MP3:
A file format with a sound data compression
system. “MP3” is the abbreviation of Motion Picture
Experts Group 1 (or MPEG-1) Audio Layer 3. By
using MP3 format, one CD-R or CD-RW can con-
tain about 10 times as much data volume as a regu-
lar CD can.
Parental Control:
A function of the DVD to limit
playback of the disc by the age of the users accord-
ing to the limitation level in each country. The limita-
tion varies from disc to disc; when it is activated,
playback will be prohibited if the software’s level is
higher than the user-set level.
PCM (Pulse Code Modulation):
A system for
converting analog sound signal to digital signal for
later processing, with no data compression used in
conversion.
Playback control (PBC):
Refers to the signal
recorded on video CDs or SVCDs for controlling
reproduction. By using menu screens recorded on a
Video CD or SVCD that supports PBC, you can
enjoy interactive-type software as well as software
having a search function.
Progressive Scan:
It displays all the horizontal
lines of a picture at one time, as a signal frame. This
system can convert the interlaced video from DVD
into progressive format for connection to a progres-
sive display. It dramatically increases the vertical res-
olution.
Region code:
A system for allowing discs to be
played back only in the region designated before-
hand. This unit will only play discs that have compat-
ible region codes. You can find the region code of
your unit by looking on the product label. Some

ALL regions).

Produces a clear picture by sending sepa-
rate signals for the luminance and the color. You can
use S-Video only if your TV has S- video In jack.
