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 pic-
ture data is compressed by 1/40 on aver-
age and stored. Variable rate encoded
technology in which the volume of data as-
signed to the picture is changed depending
on the picture format has also been adopt-
ed. 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 technology of
DVD video.
