Glossary
Analog:
Sound that has not been turned into
numbers. 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 ver tical 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 set, Stereo, etc.).
Bit Rate:
The amount of data used to hold a
given length of music; measured in kilobits per
second, or kbps. Or, the speed at which you
record. Generally, the higher the bit rate 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 composed 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 set that has Component Video In
jacks (R/G/B, Y/Pb/Pr, etc.).
Disc menu:
A screen display prepared for the
selection of images, sound, 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 OPTICAL jacks. These jacks send audio
through multiple channels, instead of just two
channels as analog does.
Dolby Digital:
A surround sound system
developed by Dolby Laboratories containing up
to six channels of digital audio (front left and
right, surround left and right and center).
DTS:
Digital Theater Systems. This is a surround
sound system, but different from Dolby Digital.
The formats were developed by different
companies.
JPEG:
A still-picture data compression system
proposed by the Joint Photographic Expert
Group, which features small decrease in image
quality in spite of its high compression ratio.
MP3:
A file format with a sound data
compression system, “MPE” is the abbreviation of
Motion Picture Experts Group 1 (or MPEG-1)
Audio Layer 3. Through the MP3 format, one
CD-R or CD-RW can contain about 10 times as
much data volume as a regular CD can.
Multichannel:
DVD is specified to have all
sound tracks constitute one sound field.
Multichannel refers to a structure of sound
tracks having three or more channels.
Parental control:
A function of the DVD to
limit playback of the disc by the age of the users
according to the limitation level in each country.
The limitation 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 without data
compression.
Playback control (PBC):
Refers to the signal
recorded on video CDs or SVCDs for
reproduction control. By using screen menus
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 (P-Scan):
It displays all the
horizontal lines of a picture at one time, as a
signal frame. This system can convert interlaced
video from DVD into progressive format for
connection to a progressive display. It
dramatically increases the vertical resolution. A
progressive scan TV set is needed to receive
progressive scan output from the system.
Region code:
A system allowing discs to be
played only in preset regions. This unit will only
play discs that have compatible region codes. You
can find the region code of your unit from the
product label. Some discs are compatible with
more than one region (or ALL regions).
S-Video:
Produces a clear picture by sending
separate signals for luminance and the color. You
can use S-Video only if your TV set has S-Video
In jack.
Sampling Frequency:
Frequency of data
sampling when analog data is converted to
digital data. Sampling frequency numerically
represents how many times the original analog
signal is sampled per second.
Surround:
A system for users to create
realistic three-dimensional sound fields full of
realism by arranging multiple speakers around
the listener.
Title:
The longest section of a picture or music
feature on DVD, music, etc., in video software, or
