DVD video disc glossary—
DVD video discs: Digital versatile disc that holds video. DVD
video discs have adopted "MPEG2", one of the world
standards of digital compression technologies. The picture
data is compressed by 1/40 on average and stored. Variable
rate encoded technology in which the volume of data assigned
to the picture is changed depending on the picture format has
also been adopted. Audio data is stored using PCM and Dolby
digital, which enables higher quality of sound. Furthermore,
multi−angle and multi−language features will also help you
enjoy the more advanced technology of DVD video.
Viewer restrictions: This feature limits what can be viewed
in conformity with a level of restrictions of the country. The level
of restrictions varies depending on the DVD video disc. Some
DVD video discs cannot be played at all, or violent scenes are
skipped or replaced with other scenes.
Level 1: DVD video discs for children can be played.
Level 2 − 7: DVD video discs for children and G−rated movie
can be played.

the same region code as the DVD player, you cannot play the
