History

The first DVD player is claimed to have been created by the Japanese electronics vendor
Toshiba , commonly known as Toshiba and stylized as TOSHIBA, is a Japanese multinational conglomerate corporation headquartered in Minato, Tokyo, Japan. Its diversified products and services include power, industrial and social infrastructure system ...
in November 1996, and the first to be released to US customers is claimed to have been by Sony in April 1997. Some manufacturers originally announced that DVD players would be available as early as the middle of 1996. These predictions were too optimistic. Delivery was initially held up for "political" reasons of copy protection demanded by movie studios, but was later delayed by lack of movie titles. The first players appeared in Japan on November 1, 1996, followed by the United States on March 31, 1997, with distribution limited to only seven major cities for the first six months. Players slowly trickled into other regions around the world. Prices for the first players in 1997 started at $600 and could top out at prices over $1000. By the end of 2000, players were available for under $100 at discount retailers. In 2003 players became available for under $50. Six years after the initial launch, close to one thousand models of DVD players were available from over a hundred consumer electronics manufacturers. Fujitsu released the first DVD-ROM-equipped computer on November 6 in Great Britain. Toshiba released a DVD-ROM-equipped computer and a DVD-ROM drive in Japan in early 1997 (moved back from December which was moved back from November). DVD-ROM drives from Toshiba, Pioneer, Panasonic, Hitachi, and Sony began appearing in sample quantities as early as January 1997, but none were available before May. The first PC upgrade kits (a combination of DVD-ROM drive and hardware decoder card) became available from Creative Labs, Hi-Val, and Diamond Multimedia in April and May 1997. In 2014, every major PC manufacturer had models that include DVD-ROM drives. The first DVD-Audio players were released in Japan by Pioneer in late 1999, but they did not play copy-protected discs. Matsushita (under the Panasonic and Technics labels) first released full-fledged players in July 2000 for $700 to $1,200. DVD-Audio players are now also made by Aiwa, Denon, JVC, Kenwood, Madrigal, Marantz, Nakamichi, Onkyo, Toshiba, Yamaha, and others. Sony released the first SACD players in May 1999 for $5,000. Pioneer's first DVD-Audio players released in late 1999 also played SACD. SACD players are now also made by Accuphase, Aiwa, Denon, Kenwood, Marantz, Philips, Sharp, and others.

; there are portable devices which have an attached LCD screen and stereo speakers. Portable DVD players are often used for long road trips and travel. They often have a plug for the 12 volt power jack in cars. Some models have two screens, so that two people in the back seat can both watch the movie. Other portable DVD players have a single screen that opens up like a laptop computer screen.


Output

Due to multiple audio (and video) output devices, there are many outputs on a DVD player, such as an RCA jack, component outputs, and an HDMI output. Consumers may become confused with how to connect a player to a TV or amplifier. Most systems include an optional digital audio connector for this task, which is then paired with a similar input on the amplifier. The physical connection is typically

The three components compare well to S-Video, which uses two wires, uniting and degrading the two color signals, and composite, which uses only wire one, uniting and degrading all three signals. The connectors are further confused by using a number of different physical connectors on different player models, RCA or BNC, as well as using

component video. However, analog RGB and S-Video signals can not be carried simultaneously, due to each using the same pins for different uses, and displays often must be manually configured as to the input signal, since no switching mode exists for S-Video. (A switching mode does exist to indicate whether composite or RGB is being used.) Some DVD players and set-top boxes offer YPbPr component video signals over the wires in the SCART connector intended for RGB, though this violates the official specification and manual configuration is again necessary. (Hypothetically, unlike RGB component, YPbPr component signals and S-Video Y/C signals could both be sent over the wire simultaneously, since they share the luminance (Y) component.)

On February 19, 2008, Toshiba, creator of the former technology, announced it would cease production on all HD DVD products, leaving Blu-ray as the high definition successor to DVD players. As technology improved, various players were sold, some of which were also Blu-ray players, that could upscale and up-convert DVD content, increasing the overall perceived picture quality.
