Miranda @ NAB 2012

Miranda Launches End-to-End Loudness Monitoring, Logging and Correction Solutions at NAB 2012

Miranda Technologies Inc. announced the launch of its end-to-end loudness monitoring, logging and correction solutions for both automatic, real-time processing during playout and file-based pre-processing prior to air and the launch of LUMO, the company's new high-density fiber converter series. LUMO packs 36 I/Os into a 1RU frame, making it the highest density electrical-to-optical and optical-to-electrical converter available in the market.

Miranda Launches End-to-End Loudness Monitoring, Logging and Correction Solutions
"With over 7000 channels of real-time automatic loudness correction deployed worldwide, Miranda is a recognized industry leader in providing unique integration of the leading loudness algorithms," says Marco Lopez, Miranda's senior vice president of Infrastructure, Routers and Monitoring. "This allows a broadcaster to perfectly match the loudness correction to its type of content."

Three new loudness-related advancements will be unveiled at NAB 2012.First, is the introduction of segment-aware loudness monitoring and logging to the Kaleido series multiviewers and the real-time loudness correction processors. Using Miranda's iControl system, broadcasters can now accurately log the average loudness per segment, enabling easy creation of detailed reports at a later date, thus enabling them to address loudness control regulations around the world, including the Calm Act in the USA.


Secondly, because the abundance of content, including most commercials, is now file-based, broadcasters can now monitor and correct content prior to playout, using Miranda's Enterprise Suite. This file-based processing provides effective loudness correction while maintaining the full dynamic range of the original content.

Finally, Miranda is introducing Intelligent Automatic Loudness Correction, which enables broadcasters to avoid audio quality problems associated with the unnecessary processing of content that has already been through loudness correction. Through tight integration between Miranda's file-based and real-time loudness correction solutions, customers can automatically turn on and off loudness correction. For example, if a commercial has already been processed using file-based loudness correction, Miranda's real-time processor will instantly detect that this content was already corrected and will turn off the automatic loudness correction.  Intelligent Automatic Loudness Correction ensures that content will never be double processed, maximizing the audio quality of the client's programming.


As Lopez, explained, "This end-to-end solution optimizes loudness processing for different types of content ensures that the highest audio quality is achieved by only performing loudness correction once, and gives you all the tools to monitor, log, and report the average loudness per segment for all of your channels. Loudness control is not just about compliance, it's also about preventing viewers from reaching for their remotes to adjust the volume. As everyone is all too aware, that remote can also tune the television to a competitor's channel."

Miranda introduces LUMO high-density fiber converter series


Miranda expands industry-leading fiber conversion portfolio
"As facilities ready themselves to carry 3Gbps signals across their infrastructures, fiber has become the cable of choice for many," says Jean-Marc d'Anjou, Miranda's vice president, Infrastructure. "Fiber cables are much more cost effective than coax, they are lighter, and take up much less space. Additionally, many system integrators now have the experience and training for installing fiber, so the cost of installation has come down considerably. Most important, though, is quality. Fiber offers the best signal integrity for high-bandwidth 3Gbps signals, and at much longer cable distances. It's also impermeable to noise or other electromagnetic interferences."

LUMO provides the best density currently on the market, converting 36 signals in a 1RU frame. These standalone devices also boast a very low impact block when compared with other standalone converters - the modular design enables each converter to be serviced while the unit remains in operation. The unit also includes dual redundant power supplies and frame controller with dual redundant IP-connections that can be used for comprehensive system monitoring and frame health alarming.


LUMO uses the same SMPTE-compliant fiber SFP modules that are found on all 3Gbps products in the Miranda portfolio. Available in regular 1310nm and CWDM wavelengths, when married with our optical CWDM mux/demux, 2 fiber cables can now carry 36 3Gbps signals.

LUMO also offers a unique cable management approach to address cable dressing concerns. Fiber connectivity is provided on one side of the unit while coax is on the other, providing for easy separation of the heavier copper cable from the lighter fiber.

Miranda's comprehensive line of fiber products meets all broadcast installation requirements. Fiber SFPs are directly available on routers, modular processors, modular distribution amplifiers, picoLinks, Kaleido-Solo, and GigE-over-fiber products. Optical splitters and optical mux/demux round out the fiber line.
