DEFINITION OF TERMS

DVD Video
This refers to a high-density optical disc on which
high-quality pictures and sound have been recorded
by means of digital signals. Incorporating a new video
compression technology (MPEG II) and high-density
recording technology. DVD Video enables esthetically
pleasing full-motion video to be recorded over long
periods of time (for instance, a whole movie can be
recorded).
DVD Video has a structure consisting of two 0.6 mm
thin discs which are adhered to each other. Since the
thinner the disc, the higher the density at which the
information can be recorded, a DVD Video has a
greater capacity than a single 1.2 mm thick disc.
Since the two thin discs are adhered to each other,
there is the potential to achieve double-sided play
sometime in the future for even longer duration play.
