SMPTE 430-9 – D-Cinema Operations – Key Delivery Bundle

This document specifies the Key Delivery Message bundle (KDMb). The KDMb is designed to deliver a set ofKey Delivery Messages [KDM] from a D-Cinema content processing center to a consumer or redistributors ofKDM elements (e.g., from post production to distribution, or from distribution to exhibition). The KDMb canrepresent an entire theatre, circuit or other grouping of recipients. The KDMb is a compressed archive thatcontains a mapping file and a directory containing a collection of one or more KDM files. The mapping filedefines a relationship between a Composition Playlist [CPL], a Recipient and a KDM. The mapping file allowsfor a fast look-up of a KDM elements for CPL or Recipient. The intent of the KDMb is to distribute a set ofKDM elements in a single compressed container for improved distribution efficiencies.
