DVD-Video is a standard for storing video content on DVD media. In the U.S., mass retailer sales of DVD-Video
titles and players began in late 1997. By June 2003, weekly DVD-Video rentals began out-numbering weekly VHS
cassette rentals, reflecting the rapid adoption rate of the technology in the U.S. marketplace. Currently
DVD-Video is the dominant form of home video distribution worldwide. (1)
Although many resolutions and formats are supported, most consumer DVD-Video discs use either 4:3 or
anamorphic 16:9 aspect ratio MPEG-2 video, stored at a resolution of 720×480 (NTSC) or 720×576 (PAL)
at 29.97 or 25 FPS. Audio is commonly stored using the Dolby Digital (AC-3) or Digital Theater System (DTS)
formats, ranging from 16-bits/48 kHz to 24-bits/96 kHz format with monaural to 6.1 channel "Surround Sound"
presentation, and/or MPEG-1 Layer 2. Although the specifications for video and audio requirements vary by global
region and television system, many DVD players support all possible formats. DVD-Video also supports features
such as menus, selectable subtitles, multiple camera angles, and multiple audio tracks. (1)
In 2006, a new format called Blu-ray Disc (BD), designed by Sony, Philips, and Panasonic, was released as
the successor to DVD. Another format, HD DVD, competed unsuccessfully with this format in the format war of
2006 to 2008. A dual layer Blu-ray Disc can store 50 GB. (1)
However, unlike previous format changes (e.g. audio tape to compact disc, VHS videotape to DVD), there is no
immediate indication that production of the standard DVD will gradually wind down, as they still dominate with
around 87% of video sales and approximately one billion DVD player sales worldwide.Consumers initially were slow
to adopt Blu-ray, partly due to the cost. By 2009, 85% of stores that sold DVD sold Blu-ray Discs. Currently,
Blu-ray players are selling for $198 USD, while titles retail for as cheap as $9.86 USD (but are usually
significantly higher in price than SD DVD releases, at a more common $20-$30 USD price). A high-definition
TV and appropriate connection cables are also required to take advantage of Blu-ray disc. Some analysts suggest
that the biggest obstacle to replacing DVD is due to its installed base; a large majority of consumers are
satisfied with DVDs. The DVD had succeeded because it offered a compelling alternative to VHS. In addition,
Blu-ray players are designed to be backwards compatible, allowing older DVDs to be played since the media are
physically identical; this differed from the change from vinyl to CD and from tape to DVD, which involved a
complete change in physical medium. (1)
