Blu-ray Disc (BD) is
a next-generation optical disc format meant for storage of
high-definition video and high-density data. The Blu-ray standard was
jointly developed by a group of consumer electronics and PC companies
called the Blu-ray Disc Association (BDA). As compared to the HD DVD
format, its main competitor, Blu-ray has more information capacity per
layer, 25 instead of 15 gigabytes, but may initially be more expensive
to produce.
Blu-ray gets its name from the shorter wavelength (405 nm) of a "blue"
(technically blue-violet) laser that allows it to store substantially
more data than a DVD, which has the same physical dimensions but uses a
longer wavelength (650 nm) red laser. Blu-ray unveiled their plans for
a Spring 2006 launch at the Consumer Electronics Show (CES) in January
2006. It will be released on May 23rd, 2006.
Blu-ray has an experimental digital rights management (DRM) feature
titled BD+ that allows for dynamically changing encryption schemes.
Should the encryption be compromised, manufacturers can update the
encryption scheme and put it on all new discs, preventing a single
crack from opening up the entire specification for the duration of its
lifetime. It also uses the Mandatory Managed Copy system allowing users
to securely rip a file into a secure format, a feature originally
requested by HP. [8] The lack of a dynamic encryption model is what
made DeCSS so disastrous in the industry's eyes: once CSS was cracked,
all DVDs from then on were crackable. See Advanced Access Content
System (AACS).
The Blu-ray Disc Association also agreed to add digital watermarking
technology to the discs. Under the name "ROM-Mark", this technology
will be built into all ROM-producing devices, and prevent content from
being reproduced in the event that a watermark is detected. Through
licensing, the BDA believes that it can eliminate the possibility of
mass producing BD-ROMs without authorization.
In addition, Blu-ray players must follow AACS guidelines pertaining to
outputs over non-encrypted interfaces. This is set by a flag called the
Image Constraint Token (ICT), which restricts the resolution for
outputs without HDCP to 960x540. The decision to set the flag to
restrict output ("down-convert") is left up to the content provider.
According to CED Magazine, Sony/MGM and Disney currently have no plans
to down-convert, and Fox is opposed to it as well. Warner Pictures is a
proponent of the ICT, and it is expected that Paramount will also
implement it. Other studios releasing Blu-ray content have not yet
commented on whether or not they will use down-conversion. AACS
guidelines require that any title that implements the ICT must clearly
state so on the packaging.
