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 sub-divided into many
sections, each of which is 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 obtained by means of digital signals.
Incorporation a new video compression
technology (MPEG II) and high-density
recording technology, DVD enable esthetic
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 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 adhered to
each other, there is the potential to achieve
double-sided play sometime in the future
for even longer duration play.
Playback control (PBC)
This is recorded on a Video CD (version
2.0). The scenes or information to be
viewed (or listened to) can be selected
interactively 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 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 re-corded on Video CDs and
CDs. 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 playback control (version 2.0).
