Figure 6: Example Show PlaylistThe final element in the Packaging system is a Packing List for the distribution package. ThePacking List contains information and identification about each of the individual files that willbe delivered in a Digital Cinema Package (DCP). This allows for asset management andvalidation, including cryptographic integrity checking, for the received DCP. A feature can besent in a single DCP or multiple DCPs and therefore could be listed in one or more PackingLists. The Packing List can be sent ahead of the DCP, for asset management purposes. Adiagram of a Packing List structure is shown in Figure 7.DCI Digital Cinema System Specification v.1.2 Page 46
Figure 7: Example Distribution Package5.3. Composition5.3.1. Track File Concepts and Requirements5.3.1.1. IntroductionThe Sound and Picture Track File is the fundamental element in the Digital Cinemapackaging system. The Sound and Picture Track File structure and requirements aredefined by the essence or metadata that they contain. Each of these essence ormetadata containers could be image, sound, subtitle (Timed Text and/or subpicture) orcaption data. However, each track file follows the same basic file structure. A track fileconsists of three logical parts: the File Header, the File Body and the File Footer asshown in Figure 8.Figure 8: Example Track File StructureThe file structure is further broken down into logical data items as defined in [SMPTE336M Data Encoding Protocol using Key-Length-Value]. The KLV Coding Protocol iscomposed of Universal Label (UL) identification Key (UL Key), followed by a numericDCI Digital Cinema System Specification v.1.2 Page 47
