Chapter number
This refers to a high-density optical disc on which high-quality
pictures and sound have been obtained by means of digital
signals. Incorporation a new video compression technology
(MPEG II) and high-density recording technology, DVD enables
esthetically 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.
Playback control (PBC)
This is only used 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 show on
the TV monitor.

This is the appearance of the dialogue at the bottom of the screen
which are prerecorded on some DVD discs.
