DCI Specs - Digital Cinema Initiatives

• This document specifies a baseline for the implementation of a Digital Cinema system.The goal of backwards compatibility in this context is to allow, for example, new contentat higher resolution and color space to be played out on a projection system that meetsthe baseline implementation.• The Digital Cinema system shall also not preclude the capability for alternative contentpresentations.• The Digital Cinema system shall provide a reliability and availability that is equal to, orbetter than, current film presentation.• Protection of intellectual property is a critical aspect of the design of the system. Thissecurity system should be designed using a single common encryption format along withkeys to decrypt the content. The method should provide a means to keep the contentencrypted from the time it is encoded in post-production until it is projected on a theaterscreen. Only trusted entities, deployed in secure environments or implementing physicalprotection, will be given access to the decrypted content. Content will be decryptedcontingent upon usage rules agreed on by content owners, Distributors and Exhibitors.The system should also be renewable in case of a breach of security in any part of thesystem, and include forensic Marking of the content for providing traceable forensicevidence in the case of a theft of the content.DCI Digital Cinema System Specification v.1.2 Page 18
