detected. In support of this, the CPL assets "KeyID" and "Hash" elements shall be present inthe CPL track file asset structure.5.5. Distribution Package5.5.1. IntroductionThe Distribution Package has two major components. One is the Package itself, whichincludes all of the Track Files and the other is the Packing List. These are all of the elementsrequired for a complete delivery to the theater Digital Cinema system. It is technicallypossible to include engagement-specific licenses and keying information in a Package in theform of opaque metadata, but this is not recommended for general usage.A Distribution Package can contain a complete feature composition or a set of compositions.Alternatively, it can carry as little as a single file to update one reel’s subtitle or sound track.5.5.2. Distribution Package5.5.2.1. GeneralThe Distribution Package is required to contain a Packing List and one or more DigitalCinema Track Files.5.5.2.2. Packing for TransportThe distribution method is required to allow a DCP to be transported via physical media,satellite or network.5.5.2.3. SecurityThe distribution method is required to provide digital signatures to allow the recipient toverify integrity of the Packing List and the enclosed files. In particular, where the DCPcontains encrypted essence files, the Packing List shall be digitally signed.Preparation of Packing Lists is a distribution fulfillment or transport function. Therefore,the digital signatures come from these entities, not the content-owner who mastered thefiles. Packing List security functions do not verify the authenticity of the content, only theintent of the delivery agent. Content authenticity is verified through signed CompositionPlaylists and validated Key Delivery Messages.5.5.3. Packing List5.5.3.1. File FormatThe Packing List is required to use XML data format with XML signature (digitalsignature). It should be in English (default) but can be provided in other languages aswell.5.5.3.2. FieldsThe following data fields are required to be included in the Packing List for each file inthe Package:• UUIDDCI Digital Cinema System Specification v.1.2 Page 55
