Definition of Terms
Angle
Recorded onto some DVD discs are scenes which have been simul-
taneously 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 subdivided into
many sections, each of which is numbered, and specific parts of
video presentations can be searched quickly using these numbers.
DVD
These refer 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 II) and
high-density recording technology, DVD enables aesthetically pleas-
ing 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
This is recorded on a video CD (version 2.0). The scenes or informa-
tion 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
These are the printed lines appearing at the bottom of the screen
which translate or transcribe the dialogue. They are recorded on
DVD discs.
Time Digit
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 recorded on
video CDs and audio 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).
