AES3 (also known as AES/EBU) is a standard for the exchange of digital audio signals between professional audio devices.
AES it is symmetric block cipher algorithm (128-bit block size, key 128/192/256 bit), adopted as an encryption standard.
A color-corrected film print made directly from the cut film negative. It is also the culmination of the creative color timing process, where final creative approval is granted before the film is duplicated for release.
Digital Audio file format developed and standardized by the EBU (European Broadcast Union, a standardization organization).
Where visual data that is normally supplemental to a motion picture is irrevocably added to the motion-picture image by compositing the data with the underlying image.
Text that is a representation, often in the same language, of dialog and audio events occurring during scenes of a motion picture. (Generally associated with a dialog and audio event translation for the deaf and hard of hearing.)
A central location where the packaged Digital Cinema content is stored for a multiple screen installation.
A section of a PNG file. Each chunk has a type indicated by its chunk type name. Most types of chunks also include some data. The format and meaning of the data within the chunk are determined by the name.
Referring to visual data that is supplemental to a motion picture being displayed off-screen.
A motion picture, or a trailer, or an advertisement, etc. Composition consists of a metadata Composition Playlist along with the essence and other metadata track files that define the work.
The definitive Playlist for specifying how a Composition is played and what track files are required.
Metadata that indicates the size of the image/structure container and the frame rate of the images – this does not indicate the image structure or resolution.
A master set of files that have not been compressed, encrypted, or packaged for Digital Cinema distribution. The DCDM contains essentially all of the elements required to provide a Digital Cinema (DC) presentation.
When the DCP is unpackaged, decrypted and decompressed, it is referred to as the DCDM*. The DCDM* is visually indistinguishable from the original DCDM.
Digital Cinema Package (DCP) the set of files that are the result of the encoding, encryption and packaging process.
Digital Source Master (DSM) a digital master created in post-production from which different versions and duplication masters may be created.
The collection of files delivered by the distributor to the exhibitor. A Distribution Package may contain pieces of a Composition or several compositions, a complete Composition, replacement/update files, etc.
A credit sequence generally shown at the end of a motion picture.
Image, audio, subtitles, or any content that is presented to a human being in a presentation.
A playlist of Compositions, describing an assembly of Compositions in sequence. An Event Playlist is typically created by a content distributor and transferred to exhibition.
Dynamic playback or distribution watermark.
Forensic Marker (FM) – Inserts markings (data indicating time, date and location of playback) in both image and audio essence in realtime at time of playback (i.e., a fingerprint or watermark inserter).
Data embedded in essence to provide forensic tracking information in the event of content theft. Such marking can be visible or non-visible, audible or non-audible.
The FMID is a unique fixed identifier of the specific instance of the Forensic Marking application.
In this architecture, metadata is first created at authoring that contains: 1) locations within the title where forensic marking may be inserted, and 2) commands that set the type of steganographic marking to be used to encode the actual forensic information. In the theater, at the time of playback, the metadata is used to instruct the inserter in the Media Block how, where, and when the required information will be hidden within the sound and/or picture.
Electronic data used to allow data encryption and decryption.
The period of time during which a given decryption key is valid. The key epoch defines a minimum practical time period for use of encrypted track files.
Key Length Value – used by the MXF to parse binary data.
Link Decryptor (LD) – Decrypts content encrypted by a Link Encryptor (LE)
Link Encryptor (LE) – Encrypts content transmission over links between physical devices in exhibition.
A storage device that is associated with an individual playback device.
Text on screen representing either non-source language dialog or information pertinent to the story such as time and place. This is specifically the text that is absent in text-less masters. This text is localized or translated for various markets either through subtitles or entire image replacement.
A credit sequence generally shown near the beginning of a motion picture.
The Media Block is the hardware device (or devices) that converts the packaged compressed and encrypted data into the streaming data that ultimately turns into the pictures and sound (raw image, sound and subtitles) in the theater.
Media Decryptor (MD) – Transforms encrypted (image, sound, etc.) content to its original plaintext form. The device located in the Media Block that decrypts the compressed content.
Data about data or data describing other data. Information that is considered ancillary to or otherwise directly complementary to essence. Information that is useful or of value when associated with the essence being provided.
National Television System Committee, which developed the NTSC television broadcasting standard.
Referring to visual data that is supplemental to a motion picture being displayed on-screen.
An MXF construct to define file structures.
A list describing the files and providing a means for authentication of the files as delivered in a package.
Exploiting limitations in the Human Visual System for data compression.
PAL - television broadcasting standard.
Playlist - conceptually, the format and structure of the various lists used to define the playback of content in Digital Cinema.
An extensible file format for the lossless, portable, well-compressed storage of raster images defined by the PNG Development Group.
A conceptual period of time having a specific duration.
A software component is renewable if it can be remotely, smoothly and possibly automatically upgraded or replaced without significantly disturbing system operations. A system shutdown and normal restart is acceptable, provided that after the restart, the system can be operated as before.
A component is said to be replaceable if it can be upgraded or replaced without significantly disturbing system operations. A system shutdown and restart is acceptable, provided that after the replacement, the system can be operated as before.
Show - the presentation that the audience sees and hears in the theater auditorium
A Playlist of Composition Playlists and Event Playlists, describing a sequence that occurs at a particular screen. A Show Playlist is typically created by exhibition and transferred to the equipment controlling a particular screen.
A multiple-image file format for the transport of visual data supplemental to a motion picture that is intended only for graphic overlay with the main image output of a digital projector.
Text that is a representation, in a different language, of dialog occurring during scenes of a motion picture. Generally associated with dialog translation for localization of a motion picture in a particular territory.
SECAM - television broadcasting standard.
Render text data onto a graphics overlay with the main image output of a digital projector.
The smallest element of a package that can be managed or replaced as a distinct asset. A track file may contain essence and/or metadata, and its duration matches an associated Reel.
A list of specified security devices which are approved to participate in playback of a particular composition at the exhibition facility.
The Universal Multiple-Octet Coded Character set, the [ISO/IEC 10646:2003] standard that defines a single code for representation, interchange, processing, storage, entry and presentation of the written form of the world’s major languages.
