Key Delivery Message (KDM)
The security key for each movie is delivered in a unique KDM for each digital cinema server. The
security key is encrypted within the KDM, which means that the delivery of a KDM to the wrong
server or wrong location will not work, and thus such errors cannot compromise the security of the
movie. The KDM is a small file, and is typically emailed to the exhibitor. To create the correct set of
KDMs for a site requires knowledge of the digital certificate in the projection system´s media block.
Digital Cinema Package (DCP)
A Digital Cinema Package (DCP) is a collection of digital files used to store and convey Digital
Cinema (DC) audio, image, and data streams. The term has been defined by Digital Cinema
Initiatives (DCI). General practice adopts a file structure that is organized into a number of usually
multi-gigabyte size Material eXchange Format (MXF) files, which are separately used to store audio
and video streams, and auxiliary index files in XML format. The MXF files contain streams that are
compressed, encoded, and encrypted, in order to reduce the huge amount of required storage and
to protect from unauthorized use. The image part is JPEG 2000 compressed, whereas the audio
part is linear PCM. The adopted (optional) encryption standard is AES 128 bit in CBC mode. The
newer SMPTE standards are used to conform the recommendations among different tool vendors
and producers. Interop, the legacy DCP standard, is still required to be supported by DCP players.
Digital Cinema Initiatives (DCI)
DCI is a joint venture of Disney, Fox, Paramount, Sony Pictures Entertainment, Universal and
Warner Bros. Studios. DCI's primary purpose is to establish and document voluntary specifications
for an open architecture for digital cinema that ensures a uniform and high level of technical
performance, reliability and quality control. Note that the DCI specification is not a standard.
Standards for digital cinema are the domain of the Society of Motion Picture and Television
Engineers (SMPTE). "DCI compliant" is a term used to describe products that conform to the DCI
specification. Products that have been tested per the DCI Compliance Test Plan (CTP) are posted
at the DCI compliance web site. Notably, DCI compliance does not require compliance to the full set
of SMPTE DCP standards. A copy of the most recent DCI specification can be downloaded from the
DCI website (

7.12 ICMP configuration via Communicator
About ICMP configuration
Following parameters are available to configure the ICMP:
•
Global settings: allows defining name of the ICMP, host name (network identifier) and IP address which
can be used for communication with external content devices.
•
User settings: definition of all users allowed on the ICMP.
•
Server settings: definition of access to servers and storage libraries of content (movies, KDM, etc.).
•
Player settings: Audio delay and audio output frequency.
•
Audio channel: allows defining the mapping of audio channels (content) on each audio output (AES
outputs of the ICMP).
•
Scheduler setting: Enable/Disable scheduler at startup, delays allowed in scheduler mode and length of
schedule history.
•
Devices: allows defining communication ports settings, to access external devices controlled by the
automation.
•
Automation Cues: event cues that are triggered from different sources and to which can be assigned
actions to be executed by the automation engine.
•
Verify internal clock of the ICMP.
All installation and maintenance operations on the ICMP are performed via Communicator, the
Barco configuration software. Please refer to the Communicator user guide for further information.
