Now , the major Hollywood film flats are split uniformly in their support fro Blu-ray and HD-DVD, but almost all of the electronics industry is presently in the Blu-ray camp. The key difference between Blu-ray disc players and recorders and current optical disc technology is that Blu-ray, as its name advocates, uses a blue-violet laser to read and write information instead of a red one. Blue light has a shorter wavelength than red light, and according to the Blu-ray Disc organisation ( BDA ), which is made of, among others, Sony, Philips, Panasonic, and Pioneer, this implies that the laser spot can be focused with larger precision. Like HD-DVD, Blue laser discs don't need a caddy and the players and recorders will be ready to play current DVD discs.
The prize is the licence charges which will be payable to the format owners when the next generation of Hi-D DVD players and recorders start shipping in volume. As hi-def TV becomes more popular , shoppers will wish to have a recordable format which has the capacity to hold at least 2 hours worth of HDTV content.
instead of get together and agree a format for Hi-D DVD, the industry has split in 2 and is manufacturing 2 different versions. Sony proposes to use Blu-ray as the format for the following generation of the PlayStation and has enrolled Disney, and MGM, and is predicted to add twentieth Century Fox to the list.
Now the major Hollywood studios are split down the middle with just about precisely half them in each camp.
HD-DVD has been developed by Toshiba and NEC and has the support of the influential DVD Forum, while Blu-ray is supported by Phillips, HP, Pointy , Pioneer, Panasonic, and Sonic Solutions.
Microsoft stands to benefit whichever format succeeds as its Windows Media nine video codec has been authorized to be used in HD-DVD and Blu-ray content.
