DVD
Tools: DVD (sometimes known as "Digital
Versatile Disc" or "Digital Video
Disc") is an optical disc storage media
format that can be used for data storage, including
movies with high video and sound quality. DVDs
resemble compact discs as their physical dimensions
are the same (12 cm (4.72 inches) or occasionally
8 cm (3.15 inches) in diameter) but they are
encoded in a different format and at a much
higher density. "DVD" was originally
an initialism for "Digital Video Disc."
Some members of the DVD Forum believe that it
should stand for "Digital Versatile Disc"
to reflect its widespread use for non-video
applications.
Toshiba, which maintains the official DVD Forum
site [1], adheres to the latter interpretation,
and indeed this appeared within the copyright
warnings on some of the earliest examples. However,
the DVD Forum never reached a consensus on the
matter, and so today the official name of the
format is simply "DVD"; the letters
do not officially stand for anything. |
