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, 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.
DVD
This refers to a high-density optical disc on which
high-quality pictures and sound have been recor
-
ded 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 recor
-
ded 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 bot
-
tom of the screen which translate or transcribe the
dialogue. They are recorded on DVD discs.
Track number
These numbers are assigned to the tracks
which are recorded on CDs.
They enable specific tracks to be located
quickly.
