A DCDM is the post-production step prior to a DCP. The frames are in XYZ TIFF format and both sound and picture are not yet wrapped into MXF files. A DCP can be encoded directly from a DCDM. A DCDM is useful for archiving purposes and also facilities can share them for international re-versioning purposes.
DCI-P3 is an RGB color space defined in 2005 as part of the Digital Cinema Initiative, for use in theatrical digital motion picture distribution [1] (DCDM [2]). Display P3 is a variant developed by Apple Inc. for wide-gamut displays.
The white point is approximate to the chromaticity of CIE Daylight with a Correlated Color Temperature (CCT) of 6000K. [2] Most ACES compliant image files are encoded in 16-bit half-floats, thus allowing ACES OpenEXR files to encode 30 stops of scene information. [1] The ACESproxy format uses integers with a log encoding.
Version 1.4.2 also implements post-show log record collection utilizing SMPTE 430-17 SMS-OMB Communications Protocol Specification. Additionally, Version 1.4.2 incorporated two prior addenda: the Digital Cinema Object-Based Audio Addendum, dated October 1, 2018 and the Stereoscopic Digital Cinema Addendum, Version 1.0, dated July 11, 2007.
Adaptive differential pulse-code modulation (ADPCM) is a variant of differential pulse-code modulation (DPCM) that varies the size of the quantization step, to allow further reduction of the required data bandwidth for a given signal-to-noise ratio.
Data Carrier Detect (DCD) or Carrier Detect (CD) is a control signal present inside an RS-232 serial communications cable that goes between a computer and another device, such as a modem.
The XYZ file format is a chemical file format. There is no formal standard and several variations exist, but a typical XYZ format specifies the molecule geometry by giving the number of atoms with Cartesian coordinates that will be read on the first line, a comment on the second, and the lines of atomic coordinates in the following lines.

Dynamic systems development method (DSDM) is an agile project delivery framework, initially used as a software development method. [1] [2] First released in 1994, DSDM originally sought to provide some discipline to the rapid application development (RAD) method. [3]
