DY/T 2.7-2020 Digital Cinema Packaging Part 7: Stereo Image Track File

This part of the "Digital Cinema Packaging" specifies a single MXF file used for encapsulating stereoscopic image content, and also specifies the new extended elements of the composite playlist (CPL) to reference this stereoscopic image track file. This part is applicable to digital cinema packaging.

DY/T 2.6-2020 Digital Cinema Packaging Part 6: Asset Mapping and File Splitting

This part of the "Digital Cinema Packaging" standard specifies a common method for mapping digital cinema packages (DCPs) to one or more file storage volumes, and defines the data structure used to map digital cinema asset identifiers to specific file storage solutions (i.e., file system paths). Assets can be stored across multiple volumes as needed, which not only enables efficient utilization of storage media but also allows for the mapping of assets that exceed the capacity of a single volume. This part specifies the structure and related details of the Asset Map and Volume Index, providing a framework for simple mapping of DCPs to various file storage systems. This part applies to digital cinema packaging.

DY/T 2.5-2020 Digital Cinema Packaging Part 5: Packaging List

This part of the "Digital Cinema Packaging" standard specifies the data format of the packaging list used for exchange in digital cinema applications. The electronic and physical forms of the complete distribution package described by the packaging list are not within the scope of this part. This part applies to digital cinema packaging.

DY/T 2.4-2020 Digital Cinema Packaging Part 4: Synthesizing Playlist

This part of the "Digital Cinema Packaging" standard specifies the structure of a composite playlist. A composite playlist is an independent presentation of a complete digital cinema work (such as a film, trailer, or advertisement). A composite playlist consists of an ordered sequence of sub-playlists, each of which references a set of external track files, such as audio track files or image track files, which will be reproduced in parallel. Each sub-playlist is similar to a sub-playlist of a film, and the composite playlist controls the order and timing of the playback of each sub-playlist. This part applies to the production of composite playlists in digital cinema packages.

DY/T 2.3-2020 Digital movie packaging Part 3: Basic data encryption of MXF trajectory files

This part of the "Digital Cinema Packaging" standard specifies the encryption syntax for non-interlaced MXF frame-wrapped track files of digital movies that comply with GY/T 293.1—2015, as well as a corresponding reference decryption model. This syntax uses the AES encryption algorithm to encrypt basic data and, as needed, verifies the integrity of the basic data using the HMAC-SHA1 algorithm. This part assumes that the keys required to decrypt and verify the integrity of encrypted track files will be provided as needed. It does not specify the management method of keys and key usage rights in digital movie distribution and screening environments, nor does it involve the use of watermarks, fingerprints, or other security technologies to provide additional protection. It does not define a universal MXF encryption framework. This part is applicable to digital cinema packaging.

DY/T 1-2020 Digital Cinema 3D projection technology requirements and measurement methods

This standard specifies the technical requirements and corresponding measurement methods for digital cinema stereoscopic projection optical systems and stereoscopic projection equipment. This standard is applicable to the measurement of digital cinema stereoscopic projection systems and equipment, and can be used to guide and standardize the research, development, production, and management of related equipment.
