West Berlin, NJ ― DaySequerra, exclusive DTS® hardware and audio partner, will introduce a
mobile media DTV loudness processor at this year’s NAB Show in Las Vegas.
Mobile handheld device speakers and ear buds have a limited dynamic range over a narrow
frequency band. This combined with noisy listening environments compromise the quality and
intelligibility of the audio content streamed to handheld mobile devices. The DaySequerra M2DTV
Mobile Media loudness processor has been optimized to keep dialog intelligible without users
constantly adjusting their volume control, even in noisy environments.
“Poor audio quality, inconsistent volume levels and unintelligible dialog, is a major challenge for
today’s mobile DTV broadcaster,” said David Day, president of DaySequerra. ”Through our
partnership with DTS and other experts, we’ve developed solid solutions to enhance the mobile
audio experience with our M2DTV,” added Day.
The M2DTV has 5.1 surround, stereo and EAS inputs, and features the industry-proven DTS
Surround Sound DownMix along with two codec pre-processing channels. Each channel is
optimized for HE AAC v2 operation at 24 kbps, 32 kbps, 48 kbps and 64 kbps to reduce artifacts
from lossy compression and low-bit rate transmissions. The M2DTV uses a proprietary perceptual
loudness model to provide accurate loudness measurements and look-ahead technology to make
large gain corrections imperceptible to viewers. It is an easy-to-operate 1RU unit complete with
industry-standard ITU-R BS.1770/1 loudness measurement on a large vacuum-fluorescent
numerical readouts and bright accurate bargraph metering, a rear panel GPIO port and Ethernet
interface for long-term logging, email alerts and field software updates.
The M2DTV will make its official debut at NAB 2011 in booth N3830. For more information on
