Video CD
Video CD (abbreviated as VCD, also known as Compact Disc Digital Video, abbreviated as CDDV) is a home video format and the first format for distributing films on standard 120 mm (4.7 in) optical discs. The format was widely adopted in all of Asia (except for Japan and South Korea), superseding the VHS and Betamax systems in those regions until DVD-Video became more affordable in the 2000s.
The format is a standard digital data format for storing video on a compact disc. VCD discs/disc images are playable in dedicated VCD players and widely playable in most DVD players, personal computers and some video game consoles with an optical disc drive that is programmed to understand VCD discs.
The Video CD standard was created in 1993 by Sony, Philips, Matsushita and JVC; it is referred to as the White Book standard. The MPEG-1 format was also released that same year.
LaserDisc was first available on the market, in Atlanta, Georgia, on December 15, 1978. This 30 cm (12 in) disc could hold an hour of analog audio and video (digital audio was added a few years later) on each side. The LaserDisc provided picture quality nearly double the resolution of VHS tape and analog audio quality far superior to cheap mono VHS recorders (although the difference to the more expensive VHS HiFi stereo recorders was minuscule).
Philips later teamed up with Sony to develop a new type of disc, called the compact disc or CD. Introduced in 1982 in Japan (1983 in the U.S. and Europe), the CD is about 120 mm (4.7 in) in diameter, and is single-sided. The format was initially designed to store digitized sound and proved to be a success in the music industry.
A few years later, Philips decided to give CDs the ability to produce video, utilizing the same technology as its LaserDisc counterpart. This led to the creation of CD Video (CD-V) in 1987. However, the disc's small size significantly impeded the ability to store analog video; thus only 5 minutes of picture information could fit on the disc's surface (despite the fact that the audio was digital). Therefore, CD-V distribution was limited to featuring music videos, and it was soon discontinued by 1991.
By the early 1990s engineers were able to digitize and compress video signals, greatly improving storage efficiency. Because this new format could hold 74/80 minutes of audio and video on a 650/700MB disc, releasing movies on compact discs finally became a reality. Extra capacity was obtained by sacrificing the error correction (it was believed that minor errors in the datastream would go unnoticed by the viewer). This format was named Video CD or VCD.
VCD enjoyed a brief period of success, with a few major feature films being released in the format (usually as a 2 disc set). However the introduction of the CD-R disc and associated recorders stopped the release of feature films in their tracks because the VCD format had no means of preventing unauthorized (and perfect) copies from being made.[citation needed] Despite this, as of 2013[update], VCDs were still being produced and released in several countries in Asia with additional copy-protection.[citation needed]
