Sun has joined the Blu-ray Disc Association (BDA) and will promote the inclusion of the JavaTM platform within the Blu-ray Disc platform. Sun's participation in the BDA is expected to be instrumental in the continued development of the multiple interactive features characteristic of the Blu-ray Disc platform.

"Blu-ray Disc offers a compelling, interactive entertainment and gaming platform that leaps substantially past current DVD standards," said Eric Chu, director, consumer and mobile systems group of Sun. "We look forward to playing a key role in supporting Blu-ray Disc's inclusion of the Java platform to provide a unique set of interactive capabilities that will create new revenue opportunities for content vendors who use Blu-ray Disc for their movies, games or other products."

The BDA is responsible for establishing format standards, promoting and further developing business opportunities for Blu-ray Disc, which is a next-generation optical disc format being developed for high-definition video and high-capacity software applications. This disc format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data.

A single-layer Blu-ray Disc can hold 25 GB, which can be used to record over 2 hours of HDTV or more than 13 hours of standard-definition TV. There are also dual-layer versions of the discs that can hold 50 GB.

The Blu-ray format uses a blue-violet laser instead of the current optical disc technologies, such as DVD, DVD±R, DVD±RW, and DVD-RAM, that use a red laser to read and write data. The benefit of using a blue-violet laser (405nm) is that it has a shorter wavelength than a red laser (650nm), which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so more data will fit on a disc that is equivalent in size to a CD/DVD. This capability, together with the change of numerical aperture to 0.85, is what enables Blu-ray Discs to hold 25 GB/50 GB.

"Sun's participation will be instrumental in the development of the many interactive features that set Blu-ray apart as a truly revolutionary step in home entertainment," said Maureen Weber, general manager, Optical Storage Solutions Business, Hewlett Packard. "Sun's addition to the Blu-ray Disc Association is another example of the tremendous, widespread support for Blu-ray Disc."

Sun will be joining an expanding list of IT organization that comprise the BDA. Represented by leading computing, consumer electronics, media, manufacturing, gaming and entertainment companies that support the Blu-ray Disc platform, this group's membership includes Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson.
