DVD video
A DVD which has moving pictures recorded on it. DVD video utilizes
MPEG2, which is one of the global standards in digital compression
technology, to compress the video data by 1/40th (on average) of its
original size.
In addition, it also incorporates variable rate encoding technology
which allows the data volume to be changed in accordance with the
shape of the picture.
Audio data can be recorded in Dolby Digital format in addition to
PCM format in order to provide a greater ambience for the sound.
A number of additional functions such as multiplex angle and
subtitling are also available to further enhance listening and viewing
enjoyment.
Parental lock (audio-visual restriction level)
This is a DVD video function which limits the ability to play back the
disc in accordance with restriction levels determined on an individual
country basis. The limits applied vary depending on the type of DVD
video, so that the disc may be completely unplayable, or scenes with
excessive violence, for example, may be cut or other scene may be
inserted in their place automatically during playback.
Titles
These are the larger of the units which are used to divide the pictures
and audio tracks which are recorded on DVD video discs into
sections. Normally it corresponds to a single movie for video
program, and a single album (or a single track) for audio programs.
The numbers which are assigned sequentially to each title are called
"title numbers". The contents of the disc can be played back by
selecting title numbers.
Chapters
These are the smaller of the units which are used to divide the
pictures and audio tracks which are recorded on DVD video discs
into sections. A single title may consist of several chapters, and the
numbers which are assigned sequentially to each chapter are called
"chapter numbers". If chapter numbers have been recorded on the
disc, they can be used for chapter search operations to skip quickly
to a desired section.
