Glossary
DVD-Video
DVD-Video is a video image storing
standard determined by the DVD forum.
“MPEG2”, a global standard in digital
compression technologies, has been
adopted which compresses on average
about 1/40th of the image data and stores
it. In addition, a variable-rate coding
technology, which changes the assigned
information amount according to the shape
of the screen image, has been adopted.
Audio information can be stored using
Dolby digital instead of PCM (Pulse Code
Modulation) and more realistic sounding
audio can be enjoyed.
In addition, various, supplementary
functions such as multi-language
availability are provided for enhanced
enjoyment.
DVD-VR
DVD-VR is short for DVD Video
Recording Format; video image storing
standard determined by the DVD forum.
Multi-angle
One of the DVD player's functions.
Because scenes can be recorded in
multiple angles (camera position), users
can choose a desired angle.
Multi-language
As a function of the DVD player, audio
or subtitles for the same video images can
be stored in multiple languages and the
language can be selected freely. Region code

be played.
A disc cannot be played if the region code
assigned to the player is not indicated on
