New Content Protection System Ready For Blu-ray Disc

June 22, 2007

“Blu-ray Disc is getting another layer of content protection with the availability of BD Plus (BD+). The system, from BD+ Technologies LLC, is now complete and available to all Hollywood movie studios and content developers for implementation in Blu-ray Disc media.

Issued by BD+ Technologies are system specifications, key management rules, test specifications and various agreements. Also launched are a key issuing center, testing centers for players, and testing facilities for disc playability.”

Blockbuster Socks HD-DVD In The Gut

June 19, 2007

While my colleague Steve Wilson is much more of a high-def optical disk expert than myself, I think this decision by Blockbuster definitely puts a chink in HD-DVD’s armor. The HD-DVD promotional group was, not surprisingly, unhappy with the decision.

“I think trying to make a format decision using such a short time period is really not measuring what the consumer is saying,” said Ken Graffeo, co-president of the group.

Its not exactly the death of HD-DVD, but I think all it would take is one more departure of a studio and the writing will be on the wall in permanent ink and spray-paint. Currently HD-DVD has exclusive support from only Paramount, while Blu-ray has Columbia, MGM, Disney, Fox and Lion’s Gate. Luckily for HD-DVD, home video behemoth Warner Brothers hasn’t shown any signs of skittishness.”

AACS Remains Confident In Protecting HD DVD, Blu-ray Disc

June 1, 2007

“Efforts that began in December 2006 and continued through February 2007 lead to the discovery of the Processing Key used to encrypt high-definition media with the Advanced Access Content System. The work of a small hacking community created essentially a silver bullet that was able to defeat the copy protection of all HD DVD and Blu-ray Disc media on the market at that time.

The Advanced Access Content System Licensing Administration (AACS LA) acknowledged the effectiveness of the hack and began to enact measures to restore the integrity of its technology. Beginning May 22, which is most notably the release date of the Matrix trilogy on HD DVD, all high-definition titles shipped with Media Key Block (MKB) v3 – a new encryption key version that would render the previously discovered Processing Key obsolete.

Interestingly enough, the AACS’ updated protection measures appeared to be defeated by SlySoft, makers of AnyDVD HD software, before the new MKB versions officially hit streets. The AACS has yet to officially issue a statement and is current investigating the latest attack on the system, according to comments made by Richard E. Doherty, director of technology strategy at Microsoft, who is also actively involved with the AACS.”

NHK Demonstrates Ultra HD Signal; 16 Times Better Than HDTV

May 30, 2007

“Although high-definition formats HD DVD and Blu-ray Disc are the bleeding edge of technology in the current consumer market, a new technology from Japan makes the latest HD movies specifications look simply archaic. Last week, engineers at NHK’s (Nippon Hoso Kyokai) Science and Technical Research Laboratories demonstrated Super Hi-Vision technology capable of a 7680×4320 resolution, reports IDG.

At 7680×4320, over 33 million pixels make up the image – this represents 16 times the resolution of a 1080p image. To get a picture of the bump in resolution, a Super Hi-Vision image could be approximated by tiling 16 of today’s best HDTVs together. In comparison, a 1080p picture represents a six-fold jump in resolution over standard-definition television.”

Legalized Blu-ray, HD DVD Copying Coming Soon

May 25, 2007

“One of the biggest arguments against digital rights management (DRM) is that it restricts users from doing what they wish with the media for which they’ve paid. For owners of high-definition movie players, such restrictions may soon be a little lighter.

The Advanced Access Content System Licensing Administration (AACS LA) says that it is now working to provide “managed copy” features on the media that uses its protection technology. HD DVD had plans to implement managed copy as part of its specification – a main reason why Microsoft and Intel stood behind the format – but Blu-ray Disc had thus far ignored the concept.

The final version of AACS will supposedly introduce methods for users to legally copy their high definition media. For example, a user may wish to copy a movie from his PC HD DVD drive onto his network for play on his PVR – and with managed copy, he may now do that without breaking copyright.”

New HD DVD, Blu-ray Disc Copy Protection Defeated Before Release

May 18, 2007

“Beginning May 22, which is most notably the release date of the Matrix trilogy on HD DVD, all high-definition titles will shipping with Media Key Block (MKB) v3 – a new encryption key version that would render the previously discovered Processing Key obsolete.

“If a set of device keys is compromised in a way that threatens the integrity of the system, an updated MKB can be provided by the AACS LA that will cause a product with the compromised set of device keys to calculate a different key than is computed by the remaining compliant products,” as found written in AACS documentation. “In this way, the compromised device keys are ‘revoked’ by the new MKB.”

However, it appears that the AACS’ updated copy protection measures have already been circumvented even before the new software’s official release. SlySoft, developers of a software used to defeat the copy protections of DVD, HD DVD and Blu-ray Disc, have revealed that its latest version of AnyDVD HD is able to sidestep the new MKB from the AACS.”
