Digital Cinema Server – LMT-300 Media Block
The LMT-300 Media Block is a digital cinema server with a large storage capacity and high reliability. It can be
seamlessly integrated into the chassis of the SRX-R320 projector, allowing for a highly secure DCI specification-
compliant Integrated Projection System. The LMT-300 can handle DCI DCP (Digital Cinema Package) 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.
Moreover, the LMT-300 incorporates the Screen Management System
(SMS) function, which lets operators manage all of the devices
necessary for digital cinema presentation from one location.

Large Storage Capacity and
Reliable RAID System
The LMT-300 incorporates HDDs with a large storage
capacity of approximately 1.7 TB. It employs a Modified
RAID 6 (Redundant Array of Inexpensive Disks) system that
allows for highly reliable digital cinema presentation.
Decryption and Unwrapping of
DCP Files
The LMT-300 can decrypt DCP files that have been encrypted
using the AES (Advanced Encryption Standard FIPS 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-300 can decode 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-300 transcodes audio DCP files into AES/EBU digital
audio signals, and then outputs them from two audio output
connectors (D-sub 25-pin) to external audio processors such
as Dolby sound processors. The audio output 1 and audio
®
output 2 can support up to 8 and 16 channels, respectively.
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.
Log Creation
The LMT-300 can generate 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.
Ingest of DCP Files During Playback
DCP files can be ingested to the LMT-300, even while
playing a movie.
