Another delay...

When Blu-ray announced their additional protection measures in August of last year, it was largely thought that the extra lockdown was there to woo content owners, especially FOX. BD+ is a dynamic encryption scheme that allows for changing encryption schemes midstream. Should the encryption be cracked, the Blu-ray Disc group can update the encryption scheme and put it on all new discs, thus preventing a single crack from opening up the entire BD spec for the duration of its lifetime. 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. AACS attempts to deal with this problem, but Blu-ray's members believed that additional protection was necessary.
Damn Sony.
