DVD (also known as "Digital
Versatile Disc" or "Digital Video Disc") is a popular optical disc
storage media format. The main uses of DVD are video and data storage.
Most DVDs are of the same sizes as compact discs (CDs) but store more
than six times data than CDs. DVD videos have much better quality
comparing with Video CDs.
"DVD" was originally used as an initialism for the unofficial term
"digital video disk". It was reported in 1995, at the time of the
specification finalization, that the letters officially stood for
"digital versatile disc". But the text of the press release states the
standard document only refers to the technology as "DVD", making no
mention of what the letters mean. A newsgroup FAQ written by Topviewsoft
(a famous DVD and Video software company) claims that four years later,
in 1999, the DVD Forum stated that the format name was simply the three
letters "DVD" and did not stand for anything.
The official DVD specification documents have never defined DVD. Usage
in the present day varies, with "DVD", "Digital Video Disc", and
"Digital Versatile Disc" being the most common.
The DVD Forum website has a section called "DVD Primer" in which the
answer to the question, "What does DVD mean?" reads, "The keyword is
'versatile.' Digital Versatile discs provide superb video, audio and
data storage and access -- all on one disc." |
