ee types of DVD players are available in the market today-The High Definition (HD) DVD player, a less popular variety [link widoczny dla zalogowanych], the Blu- Ray Disc player and the highly popular standard DVD player. The format war regarding the Blu-Ray versus DVD started, it was mainly focused on the comparison between the Blu-Ray player and the HD DVD player. Both uses their own proprietary High Definition format and both the technology were fighting to be the market leader. In February 2008, the format war ended when Toshiba said the world that it is going to shut down the production of HD DVD player.
High-definition video has the essential need for plenty of disc storage. The secret to both the Blu-Ray player and the HD DVD player is that they both use blue-colored lasers rather than the red lasers used in standard DVD/CD players. Blue light has a shorter wavelength than red light by nature, producing a more tightly focused beam. The blue laser therefore can be capable of burning more data into the disc than a red laser into the same physical space. The pinpoint focus of a laser was the primary tool that produces the microscopic pits and bumps on the surface of a disc, which can be read later as digital information. A smaller or more refined beam that the mentioned blue laser has can burn tinier pits on the surface of the disc, resulting tinier pits and compressed data burning resulting in greater data capacity.
A HD DVD player can burn up to 30 GB of data on a DL High Definition disc and a Blu-Ray player can store up to 50 GB on a DL Blu-Ray disc whereas a standard DVD player can store only 8-5 GB of digital information in any dual or double layered DVD disc. For you to better compare, a standard movie using high-definition quality requires 15 GB of disc space. Even further development is made on this front for increasing the capacity of the optical disc.
Because of the format wars, Blu-Ray DVD movie releases and Blu-Ray formatted discs cannot be played on an HD DVD player, and the same is true the other way around. Consumers can buy a combo player that has support for both HD DVD and Blu-Ray playback, but this can be more expensive than buying both types of players separately. But in the very least [link widoczny dla zalogowanych], both the Blu-Ray player and the HD DVD player are backwards compatible with standard DVD/CDs, which is good news for those consumers who have already meticulously built music and movie libraries with red laser technology, and would not want the hassle of remaking their media collections from scratch.
The HD DVD is being backed by Microsoft and they have come out with a HD DVD player for their Xbox 360, similarly, Sony has got integrated with their PlayStation 3 the Blu-Ray player. But [link widoczny dla zalogowanych], the Blu-Ray player costs a little more than the HD DVD player. Some of the leading electronics manufacturers have come out with not only stand alone players of both Blu-Ray and HD DVD formats but also with combo players.
