Blu-ray Disc Association Responds To Microsoft/Intel

Postby Ian on Fri Sep 30, 2005 8:28 am

And they finally respond...

Some of their facts:

Capacity: Blu-ray Disc's capacity is 50GB. This will be available at
launch for BD-ROM, BD-R, and BD-RE. This is 67% more than HD-DVD's 30GB
ROM capacity and 150% more than its recordable storage capacity -- a
critical issue for computer users.

Managed copy: Managed Copy is not a function of the optical disc format,
but a function of the content protection system. The AACS content
protection system, which is used by both Blu-ray Disc and HD-DVD, enables
managed copy and network streaming functionality. It is not format
specific.

Hybrid Disc: Blu-ray Disc was the first format to introduce a hybrid
disc that could hold both high and standard definition versions of a
movie on a single disc. The Blu-ray Hybrid Disc is the more elegant
solution as it holds both versions of the film on the same side of the
disc, which provides for easy labeling and greater ease of use for
consumers.

Backward Compatibility: Blu-ray Disc players and recorders can and will
support DVDs through the addition of red lasers in the hardware. In
order to be backward compatible with DVD, HD-DVD must also include a red
laser.

Interactivity: Blu-ray disc is built on BD-Java(TM), which leverages
years of industry investment and experience in the set-top box, PC, and
cell phone industries. BD-JavaTM provides a mature, robust platform for
authoring and delivering unprecedented interactive capabilities to the
user for movies, music, and games. BD-Java was selected over iHD, the
developmental Microsoft technology used in HD-DVD. The BDA carefully
compared both iHD and BD-J, and concluded that iHD didn't go far enough
in providing a compelling feature set beyond DVD, while BD-J offered
studios a much richer palette for providing a compelling interactive HD
experience for consumers, particularly when a player is connected to a
network.

Blu ray is clearly the future. I think they just wanted things to move along in an incremental fashon, they like having their next paycheck secure.

BluRay seems to imply that HDDVD does NOT have a dual layer HDDVDR ready yet... only HDDVD-ROM :o

it implies that HD-DVD ROM is 30GB and recordable HD-DVD is only 20GB.
is this true ?

Single layer HD DVD-R is 15GB. Double is 30GB.

I believe I read somewhere that they have a triple layer at 45GB. Blu-Ray has single layer at 25GB, double layer at 50GB, and I think a quad layer at 100GB. :o

It's been said that the largest disc expected from BluRay is a Quad 100GB disc... not sure about HDDVD though, I THOUGHT they could have up to 4 layers as well, but maybe it's only 3?

What's wrong with Verbatim DVD+RDL?

that they're the ONLY ones to get it right.
what would think of the CD-R media market if there were only one manufacturer ?

IMO you can't really say that DVD+DL as a concept has succeded.

That's because the only company competing with Verbatim is Ritek... if CMC were pushing it harder, and if Optodisc hadn't decided it was completely uninterested, I think we'd be seeing a much different market.

Well, regardless of the advantages, they ultimately chose the HD DVD format because it was progressing much faster than Blu-ray.
