Cobalt® LMNTS (Loudness Management for n-Transport Streams) is a first in comprehensive transport-based loudness processing. LMNTS represents a new level in multi-stream loudness processing integration, ease, economy, confidence, and consistency. Operating at the MPEG transport layer, LMNTS provides a practical loudness management solution for MVPD operators without the need or complexity of external codecs transferring between baseband and MPEG interfaces.
Using unique depacketing/repacketing processing and decode/re-encode, LMNTS extracts and decodes audio codec packets from the program stream, performs high-quality PCM loudness processing, and then re-encodes and re-packets the audio with its stream. An ASI option provides additional ASI transport stream support. Physically, all data connection to LMNTS is via GigE IP or ASI interfaces using an industry-standard IT hardware platform with no intermediary breakouts.
Because LMNTS uses the same high-quality Linear Acoustic® Aeromax™ loudness processing for each stream, perfect loudness consistency is assured for all programming passing through the system. For AC-3 streams, LMNTS can accommodate varying received loudness and dialnorm, and repackage the audio using consistent loudness and consistent re-authored dialnorm for perfect loudness matching for all programming.
LMNTS is fully scalable, with licenses available to progressively add the number of audio programs accommodated.
Key Features
Unmatched integration ease and practicality for multi-stream head-end loudness processing. Directly interfaces with GigE-based playout servers.
Integrated HTML5 user interface for easy setup and local or remote monitoring
ASI option provides ASI transport stream processing
Low delay latency (500 msec)
Consistent, uniformly controlled loudness processing across all program channels (including interstitials). Loudness processing performed in PCM domain.
Post-processed AC-3 is re-encoded using re-authored matching dialnorm across all programming
Full compatibility with MPTS and SPTS streams
Integrated video/audio delay re-alignment compensates for any internal processing delays
Transparent processing maintains payload size and video/audio quality. No added re-compression or de-compression.
Three year warranty with extension options available

Capacity
LMNTS-500
Data throughput: (3) GigE (1000 Base-T) RJ-45 Media Ports
Channel capacity: Up to 10 surround audio PIDs; up to 25 stereo audio PIDs (see Note
below)
Processing latency delay: 500 msec
LMNTS-1000
Data throughput: (5) GigE (1000 Base-T) RJ-45 Media Ports
Channel capacity: Up to 60 surround audio PIDs; up to 100 stereo audio PIDs (see Note
below)
Processing latency delay: 500 msec
LMNTS-2000
Data throughput: (5) GigE (1000 Base-T) RJ-45 Media Ports
Channel capacity: Up to 100 surround audio PIDs; up to 140 stereo audio PIDs (see Note
below)
Processing latency delay: 500 msec
Note: Channel capacities above are typical maximum capacities. Practical capacity is a function of licenses added. Capacity is based on processing “credits”.
For example on LMNTS-500, 100 credits are available for which each surround PID consumes 10 credits, and each stereo PID consumes 4 credits. Any combination of stereo and surround PIDs can be supported, noting the total available processing credits.
For any of the models listed above, a Cobalt Sales Manager can assist you in determining the maximum processing capacity to support your requirements.
