标准摘要
[中文适用范围]： 本文件规定了密钥传递消息捆绑包（KDMb）。KDMb 旨在将一组密钥传递消息 [KDM] 从数字电影内容处理中心交付给消费者或 KDM 元素的再分发者（例如，从后期制作到发行，或从发行到放映）。KDMb 可以代表整个影院、电路或其他接收者分组。KDMb 是一个压缩归档文件，包含一个映射文件和包含一个或多个 KDM 文件的目录。映射文件定义了构图播放列表 [CPL]、接收者和 KDM 之间的关系。映射文件允许快速查找与 CPL 或接收者相关的 KDM 元素。KDMb 的意图是在单个压缩容器中分发一组 KDM 元素，以提高分发效率。 [外文原描述]： ISO 26430-9:2009 specifies the Key Delivery Message bundle (KDMb). The KDMb is designed to deliver a set of Key Delivery Messages (KDM) from a D-cinema content processing centre to a consumer or redistributors of KDM elements (e.g. from post production to distribution, or from distribution to exhibition). The KDMb can represent an entire theatre, circuit or other grouping of recipients. The KDMb is a compressed archive that contains a mapping file and a directory containing a collection of one or more KDM files. The mapping file defines a relationship between a Composition Playlist (CPL), a Recipient and a KDM. The mapping file allows for a fast look-up of KDM elements for CPL or Recipient. The intent of the KDMb is to distribute a set of KDM elements in a single compressed container for improved distribution efficiencies.
