(b) 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.
