SPDC is basically a virtual machine system that actually allows the c
opy protection code to be stored on the disc alongside the content. Am
ong other things this allows the copy protection system to actually be
changed on a per-title basis. So if a hacker figures out how to crack
, say, AACS 1.0, then AACS 2.0 can fix the flaw and all subsequent tit
les can be released using AACS 2.0---without requiring that people rep
lace their players.
