In short, a Digital Cinema Package (DCP) is a specially prepared collection of video, audio, subtitles and data used specifically for Digital Cinema. DCP is the standard to create versions of a feature or short that are compatible with cinema digital playback systems, and also adds optional encryption via a KDM key (Key Delivery Message) to combat piracy. DCP’s are encoded following strict guidelines put forth by the Digital Cinema Initiatives, a governing body created by the major studios in 2002 to establish consistency and quality specifications for DCP creation.
KDM (Key Delivery Message) encryption is a tool used in the industry to curb piracy of films. When a DCP is created serve, it can be encrypted in such a way that it can only be played on a specific playback r at a set time. A KDM “key” is sent to the theater on a flash drive to “unlock” the feature for playback. Encryption is instrumental in protecting films from misuse or theft, but is not mandatory.
We can provide and highly recommend the use of a Linux formatted CRU drive, which are designed specifically for digital cinema. CRU drives are the world-wide standard for DCP, and are the preference of digital cinema projections.
