Angle
Recorded onto certain special edition DVD discs are scenes that 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.
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
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 tech-
nology, 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 even longer duration play.
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 spe-
cific 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 num-
bered as title 1, title 2, etc.
Track Number
These numbers are assigned to the tracks which are recorded on audio CDs. They enable specific tracks to be
located quickly.
