Definition of terms

DVD
This refers to a high-density optical disc on which high-quality pictures and sound have been
obtained by means of digital signals. 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.
Video CD
This contains recordings of pictures and sound whose quality is on a par with video tape. This
player also supports Video CDs with playback control (version 2.0).
MUSIC
These contain recordings of music which are compressed, allowing a significantly larger
amount of music to be stored on a CD.
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.
Subtitles
This is the appearance of the dialogue at the bottom of the screen which are prerecorded on
some DVD 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.
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.
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.)
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.
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.
