The
Video Content Protection System (
VCPS) is a
standard for
digital rights management, intended to enforce protection or DVD+R/+RW content and related media.
It was designed to protect video recordings broadcast terrestrially with the
broadcast flag used for
digital high-definition programming, but it's use has been expanded to
cover programming obtained in other ways, such as via cable and satellite delivery. This standard is promoted by
Philips and is included in latest Scsi MMC-6 specification.
The system makes use of three different classes of encryption key, one type stored on the media
in a "Disc Key Block", one stored in player software, and one in any hardware device
that will be used to play (and hence decrypt) the media.
