Definition Of Terms
Angle
Recorded onto some DVD discs are scenes, which have been simultaneously shot from a
number off 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 differ-
ent angles.
Chapter Number
These numbers are recorded on DVD discs. A title is subdivided into many sections, each of
which are numbered, and specific parts of video presentations can be searched quickly us-
ing these numbers.
DVD
This refers 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 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 oven longer duration play.
Playback Control
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
These are printed lines appearing at the bottom of the screen, which translate or transcribe
the dialogue. They are recorded on the DVD discs.

This indicates the playtime, which has elapsed from the start of a disc or a title. It can be
used to find a specific scene quickly. (Not all discs permit the time search feature to be used.
Availability is determined by the discs manufacturer.)
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 AudioCDs. They enable
