V. Digital Cinema Package (DCP)
DCP creation is the final step in film production for the delivery of a digital high-resolution master for distribution to digital cinema screens. A Digital Cinema Package is a digital film print, with a special data format for picture and sound. The specifications for it have been set by the Digital Cinema Initiatives, a cooperation of 7 big Hollywood studios in the “Digital Cinema System Specifications”. The aim was to set up one standard for digital cinema preventing concurrence of different formats, which would have made things a lot more complicated when distributing a film worldwide. Another goal was to set up a standard with a high security against piracy. The DCI standard is now widely accepted as the successor of 35 mm film, because of its open standard, the absence of any license fee, the high security level and the superior image and sound quality. A DCP consists of the media files, a packing list (PKL) and one or more composition playlist s (CPL). These composition playlists contain the information on which picture and sound files go together and in which order they should be played. It is possible to store several language versions in one DCP without having to save the redundant information (e.g. the picture files) twice, enabling an efficient usage of disk space. Depending on the bitrate a Digital Cinema Package consumes about 1.5 to 2 GB of storage space per minute of duration.
