Digital Cinema Server – LMT-100 Media Block
10
Audio
The LMT-100 transcodes audio DCP files into AES/EBU digital
audio signals and 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 synchronisation 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.
Decryption and Unwrapping
of DCP Files
The LMT-100 can decrypt DCI-compliant DCP files that have
been encrypted using the AES (Advanced Encryption
Standard PSP 197) and 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.
The LMT-100 Media Block is a digital cinema server
that can handle DCI-compliant DCP files, which is
a key component in establishing highly secure
theatre systems. The LMT-100 server handles
DCP (Digital Cinema Package) files that consist of
picture, audio and subtitle data files that are
wrapped into an MXF (Material eXchange Format)
file. It plays back the DCP file 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 Sony LSM-100
SMS (Screen Management System) software.
