DVD Players

A DVD player is a device that plays discs produced under both the DVD-Video and DVD-Audio technical standards, two different and incompatible standards. These devices were invented in 1994 and continue to thrive. However, with the release of high definition media, sales and popularity is expected to drop in the upcoming years.

Blu-ray Disc (official abbreviation BD) is an optical disc storage medium designed to supersede the DVD format. The format defines as its standard physical media a 12 cm (same as DVDs and CDs), 25 GB per-layer optical disc, with dual layer discs (50 GB) the norm for feature-length video discs and additional layers possible later.
The name Blu-ray Disc refers to the "blue laser" used to read the disc, which allows for six times more storage than on a DVD.
Blu-ray Disc was developed by the Blu-ray Disc Association, a group representing makers of consumer electronics, computer hardware, and motion pictures. As of June 2009, more than 1,500 Blu-ray Disc titles were available in Australia and the United Kingdom, with 2,500 in the United States and Canada.[2] In Japan as of July 2010 more than 3,300 titles were released.
