DVD VIDEO DISC GLOSSARY
DVD video discs: Digital Versatile Disc
that holds video. DVD video discs have
adopted "MPEG2", one of the world stan-
dards 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 as-
signed to the picture is changed depend-
ing 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
users enjoy the more advanced technolo-
gy of DVD video.
