DVD
This refers to a high-density optical disc on which high-quality pictures and
sound have been recorded by means of digital signals. Incorpor-ating a new
video compression technology(MPEG II) and high-density recording
technology, DVD enables 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 0.6mm thin discs which are ad-hered
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 1.2mm 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.
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.
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.
Recorded onto some DVD discs are scenes which have been simult-
aneously shot from a number of different angles(the same scene is shot
from the front, front the left side, from the right side, etc.). With such discs,
the ANGLE button can be used to view the scene from different angles.
Track number
These numbers are assigned to the tracks which are recorded on CDs.
They enable specific tracks to be located quickly.
