Special characteristics of DVD-Video:
• Up to 8 hours of feature films on a single DVD.
• Up to 8 audio tracks and 32 subtitle tracks.
• Greater picture quality than VHS or SVHS.
• Time-frame navigation and picture stills.
• Selection of different camera angles in some media.
• Parental Control, in which certain scenes or an entire
film or rating of films can be made accessible only to cer-
tain age groups. DVD players can, for example, be set so
that scenes or films which have not been approved for
younger audiences will not play.
In spite of the high storage capability of the DVD the data must
be extremely compressed in order for a complete feature film to
be stored.

Regional Playback Information for DVD

The playback of DVD movies includes the decoding of MPEG2 vid-
eos, digital AC3 audio data and the deciphering of CSS protected
contents.
CSS (sometimes called copy guard) is the name of a data protec-
tion program incorporated by the movie industry as an action
against illegal copies.
Among the numerous regulations for CSS licensees the most im-
portant ones are the country specific playback restrictions.
In order to facilitate the geographically restricted release of mov-
ies, DVD titles are released for certain regions.
Copyright laws require the restriction of each DVD movie to a cer-
tain region (usually the region, in which it is sold).
DVD movie versions can be published in several regions but the
CSS regulations require that each CSS decipherable system may
only be used in one region.
