Digital Cinema Content Security and the DCI

This paper describes the content security system defined in the DCI digital cinema system specification. This specification is not a standard and is not a complete specification to which systems can be built. Rather it represents a sketch of how the major U.S. studios would like to see digital cinema systems develop. Many of the ideas in the specification will be implemented and others will be revised as the motion picture industry adopts and then transitions to digital cinema. As digital cinema systems are built and deployed, standards organizations such as SMPTE and ISO will further refine the functionality and interoperability requirements of various digital cinema components.
