2. DVD-Video
2.1. General
DVD-Video is a new media for the distribution of
home videos. The digital nature of this new media
offers several new features to the consumer.
Amongst those features are:
High video quality based on MPEG2 compression
and the ability to playback both aspect ratios of
4:3 and 16:9.
A DVD-Video can hold up to 8 different audio
tracks (streams). Each track can be used for a
different language. It can also be utilised for high
quality stereo audio with a resolution of 16 bit
and 48 kHz, or for theatre quality surround
audio, like Dolby Digital AC-3.
Up to 32 different streams of subtitles can be
placed on a DVD-Video, used as language
subtitles, as menu highlights or as instructions
for interactive functions.
Digital copy protection via CSS and analogue
copy protection via Macrovision.

Multibranching is another feature of DVD-
Video that simply offers the possibility to
playback one title with different parts of this
title, which can be interactively selected by the
viewer. In addition the multiangle option
allows a scene of a movie title to be viewed in
different angles.
Every DVD-Video player implies a region code
corresponding to one of the six regions in the
world where it is sold. This regional coding
optionally enables playback of a DVD-Video title
only in certain regions.
DVD-Video discs can be prepared with a
'Parental Lock' in order to restrict the playback
only by usage of a correct password.

Video. For detailed information please refer to our
