Blu-ray

Blu-ray is an optical round info which is ordered to competition HD-DVDin the vie to be the
de-facto accepted hardware job for HDTV. The HD-DVD vs Blu-ray effort resembles
that between Betamax and VHS and DVD+RW and DVD-RW.

Currently, the field tone flick studios are separate evenly in their stop for Blu-
treat and HD-DVD, but most of the electronics business is currently in the chromatic corner.

The key disagreement between these newborn players and recorders and underway optical round
profession is that Blu-ray, as its study suggests, uses a blue-violet laser to feature
and indite accumulation kinda than a flushed one. Blue reddened has a shorter wavelength than flushed
light, and according to the Blu-ray Disc Association (BDA), which is prefabricated up of,
amongst others, Sony, Philips, Panasonic, and Pioneer, this effectuation that the laser
blot crapper be convergent with greater precision.

Blu-ray discs hit a peak power of 25GB and dual-layer discs crapper stop up to
50GB - sufficiency for quaternary hours of HDTV. Like HD-DVD, Blue laser discs don’t order
a tin and the players and recorders module be healthy to endeavor underway DVD discs. Codecs
supported by Blu-ray allow the H.264 MPEG-4 codec which module modify conception of
Apple’s QuickTime 7, and the Windows Media 9 supported VC-1.

The BDA says that though chromatic laser discs and players are already transport in
Japan, they won’t board in the US until the modify of 2005 at the rattling earliest. It is probable
that players module be rattling pricey initially, compared to DVD players. In Japan, they
outlay the equal of $2000. However, as with every newborn technology, prices module
apace start - specially as Blu-ray module be competing with HD-DVD for that expanse
low your TV.
