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 different angles.
Chapter number
These numbers are recorded on
DVD
discs. A title is subdivid­
ed into many sections, each of which is numbered, and specif­
ic parts of video presentations can be searched quickly using
these numbers.
Digital audio output connector (Optical)
The digital audio output connector (optical) converts electrical
signals into optical signals and transfers them to the amplifier.
Consequently, it has a number of features including its immu­
nity from electrical interference from external sources and its
ability to prevent the generation of noise and its minimal effect
on the external environment.
DVD
This refers to a high-density optical disc on which high-quality
pictures and sound have been recorded by means of digital
signals. Incorporating a new video compression technology
(MPEG 2) and high-density recording technology, DVD en­
ables esthetically pleasing full-motion video to be recorded
over long periods of time (for instance, a whole movie can be
recorded).
DVD has a structure consisting of two 0.6 mm thin discs which
are adhered to each other. Since the thinner the disc, the high­
er 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 adhered to each other, there is the
potential to achieve double-sided play sometime in the future
for even longer duration of play.
Field
Half of the video information (video signal) in a frame is called
a field. With conventional TV systems, a signal frame (a single
screen) consists of two fields.
Field still
Only one field (half of the video information) is displayed on the
TV screen, so the apparent resolution is low. However, there is
no blurring on the screen.
Frame
Individual images in a video or on the TV are called frames.
Frame still
The two fields are displayed, alternately, on the TV screen, so
the image is blurry. However, the image quality is better than
field images.
Playback control
This is recorded on a Video CD (version 2.0). The scenes or
information to be viewed (or listened to) can be selected inter­
actively with the TV monitor by looking at the menu shown on
the TV monitor.
Subtitles
This is the appearance of the dialogue at the bottom of the
screen which are prerecorded on some DVD discs.
Time number
This indicates the play time which has elapsed from the start of
a disc or a title. It can be used to find a specific scene quickly.
(It may not work with some discs.)
Title number
These numbers are recorded on DVD discs. When a disc con­
tains 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 Video CDs and CDs. They enable specific tracks to be lo­
cated 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 playback control (version 2.0).
