Definition of Terms
Angle
Recorded onto some DVD discs are scenes,
which have been simultaneously shot from a
number of different angles (the same scene is
shot from the front, from the left side, from the
right side, etc.). With such discs, the ANGLE
button can be used to view the scene from dif-
ferent angles.
Chapter Number
These numbers are recorded on DVD discs. A
title is subdivided into many sections, each of
which are numbered, and specific parts of video
presentations can be searched quickly using
these numbers.
DVD
This refers to a high-density optical disc on which
high-quality pictures and sound have been re-
corded by means of digital signals. Incorporat-
ing a new video compression technology
(MPEG II) and high-density recording technol-
ogy. DVD enables aesthetically pleasing full-
motion video to be recorded over long periods
of time (for instance, a whole movie can be re-
corded).
DVD has a structure consisting of two 0.6-mm
thin discs, which are adhered to each other. Since
the thinner the disc, the higher the density at
which the information can be recorded, a DVD
disc has a greater capacity than a single 1.2
mm thick disc. Since the two thin discs are ad-
hered to each other, there is the potential to
achieve double-sided play sometime in the fu-
ture for even longer duration play.
Playback Control
This is recorded on a Video CD (Version 2.0).
The scenes or information to be viewed (or lis-
tened to) can be selected interactively with the
TV monitor by looking at the menu shown on
the TV monitor.
Subtitles
These are printed lines appearing at the bot-
tom of the screen, which translate or transcribe
the dialogue. They are recorded on the DVD
discs.
Time Number
This indicates the playtime, which has elapsed
from the start of a disc or a title. It can be used to
find a specific scene quickly. (Not all discs per-
mit the time search feature to be used. Avail-
ability is determined by the disc’s manufacturer.)
Title Number
These numbers are recorded on DVD discs.
When a disc contains two or more movies, these
movies are numbered as title 1, title 2, etc.
Track Number
These numbers are assigned to the tracks,
which are recorded on AudioCDs. They enable
specific tracks to be located quickly.
Video CD
This contains recordings of pictures and sound
whose quality is on a par with that of videotape.
This player also supports Video CDs with play-
back control (Version 2.0).
Dolby Digital
Many movie theatres are equipped with 5.1 chan-
nel surround systems. This same type of tech-
nology is available to you in your home. To enjoy
full 5.1-channel surround, your DVD player must
be connected to an external Dolby Digital de-
coder via the digital outputs (either coaxial or
optical).
Dolby Pro Logic
This is Dolby Laboratories’ technology to de-
code Dolby Surround encoded programs ac-
tively. Dolby Surround programs have four chan-
nels of audio (Left, Center, Right and Surround)
encoded into a standard 2-channel stereo sig-
nal. The rear channel is monaural.
LPCM
LPCM stands for Pulse Code Modulation and is
digital audio.
MPEG
Short for Moving Picture Experts Group. This is
an international standard for compression of
moving images. On some DVDs digital audio
has been compressed and recorded in this for-
mat.
