DVD video discs: Digital Versatile Discs that hold world's standard video.
l
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 has been
adopted in which the volume of data assigned to the picture is changed
depending on the picture format. Audio data is stored using PCM and
Dolby digital, which enables higher sound. Furthermore, multi-angle and
multi-language features will also help you enjoy the more advanced tech-
nology of DVD video.
