Decryption and Unwrapping of
DCP Files

The LMT-100 can decrypt DCP files that have been
encrypted using the AES (Advanced Encryption Standard PSP
197). It can also unwrap individual picture, audio, and
subtitle data files for processing that are encoded within the
MXF file.

Picture and Subtitle

The LMT-100 can decode the JPEG 2000 picture data in real
time for playback, regardless of whether the file was encoded
at 2K or 4K resolution. Subtitles in Timed-Text/XML or
PNG/XML format can be overlaid onto picture data before it
is sent to the projector.

Audio

The LMT-100 transcodes audio DCP files into AES/EBU
digital audio signals, and then outputs them to external audio
processors. Up to 16 channels can be output from D-sub
25-pin or BNC connectors. The timing of the audio output
can be adjusted for complete synchronization with the
picture, and any channel can be routed to any output to
simplify installation.

Event Log Creation

The LMT-100 can generate event logs* to record certain
information - such as the number of times a movie has been
played - which is a DCI requirement for secure content
control.

* Requires the optional SMS software.

The LMT-100 Media Block is a digital cinema server that can
handle DCI DCP files, which is a key component in
establishing highly secure theatre systems.
The LMT-100 server handles DCP (Digital Cinema Packages)
files that consist of picture, audio, and subtitle data files, and
that are wrapped into an MXF (Material eXchange Format)
file. It can play back the DCP file by using advanced
processing to decrypt and decode the picture data, and then
send it to the projector over a secure multi-pin connection
system.
The LMT-100 server is controlled with the optional SMS
(Screen Management System) software.
