Renewing the AACS encryption key
You may have to renew the AACS encryption key to play content such as movies on commercially available BD video software (BD-ROM). The encryption key is renewed when you perform a system software update.
AACS (Advanced Access Control System) is a copyright-protection technology that is used on Blu-ray Discs. The copyrighted content is protected by setting an encryption key on both the disc and the device used to play the disc.
An AACS encryption key expires in 12 to 18 months and must be renewed. There may also be other times when the key has to be renewed.
