Title (DVD video discs only)

example the main feature could be title 1, a documen-
tary describing how the film was made could be title 2,
and cast interviews could be title 3. Each title is
assigned a reference number enabling you to locate it
easily.
Chapter (DVD video discs only)
A chapter is a segment of a title such as a scene in a
film or one interview in a series. Each chapter is
assigned a chapter number, enabling you to locate the
chapter you want. Depending on the disc, chapters
may not be recorded.
Scene (VCD)
On a video CD with PBC (Playback control) functions,
moving pictures and still pictures are divided into sec-
tions called “Scenes”. Each scene is displayed in the
menu screen and assigned a scene number, enabling
you to locate the scene you want. A scene is com-
posed of one or several tracks.
Track
A distinct element of audiovisual information, such as
the picture or sound track for a specific language
(DVD), or a musical piece on a video or audio CD.
Each track is assigned a track number, enabling you to
locate the track you want. DVD discs allow one track of
video (with multiple angles) and several tracks of
audio.
Types of video CDs

Video CDs equipped with PBC (Version 2.0)

with the system via menus, search functions, or other
typical computer-like operations. Moreover, high reso-
lution still pictures can be played if they are included
on the disc.
Video CDs not equipped with PBC (Version 1.1)
Operated in the same way as audio CDs, these discs
allow playback of video pictures as well as sound, but
they are not equipped with PBC.
