GatesAir Brings New
Over-the-Air Broadcast
Innovations to NAB Show
Next-generation Maxiva over-the-air platforms for LPTV accelerate ROI and optimise digital television
spectrum, while new VMXpress IP edge device extends network capabilities for radio broadcast studios...

G

atesAir will introduce a range of
new transmitters, audio transport
system enhancements, and studio
networking technologies at the 2015
NAB Show. At press time, GatesAir
has unveiled plans for low-power
TV networks and radio broadcast
studios that align with its core
message of over-the-air efficiency and
intelligent networking, for over-the-air
broadcasters.
For
television,
GatesAir
will
introduce high efficiency, low power
transmitter and gap filler solutions,
which affordably solve the challenges
of high penetration across large DTV
networks, while delivering the lowest
total cost of ownership. The new
solutions specialise in delivering high
quality digital TV services over the air,
to regions lacking coverage by higher
power transmitters, reliably filling in
hard to reach areas.
At NAB Show, GatesAir will display
two new low power TV platforms
that address two distinct needs. The
Maxiva Ultra-Compact series offers
standalone low power translator and
on-channel gap filler solutions for UHF
and High Band VHF stations, across
four power levels (30, 50, 80, and 130
watts). The new solution cuts the rack
space requirements of its predecessor
by 50%, delivering a broadband 1RU
solution with exceptional performance
and efficiency.
The Maxiva Multi-Compact series
comprises high density, 4RU 19
inch rack-mounted UHF and VHF
transmission systems, available in
several configurations, including
N+1, N+2, or N+1+M+1 redundancy.
The
innovative
Multi-Compact
series provides a single chassis to
house up to eight separate 15 W
transmitters, translators or on-channel
gap fillers, and provides the most
compact design available, along with
multiple redundancy options and
configurations.

Both solutions share performance
and efficiency attributes with marketleading medium-to-high power Maxiva
transmitters, balancing exceptional
over-the-air quality with a green,
cost-reducing
architecture
that
slashes energy consumption, power
bills, and maintenance requirements.
Additionally, both systems are fully
broadband across UHF and High VHF,
ensuring a frequency agile design that
removes any concerns about future
spectrum re-pack. The broadband
design also greatly reduces spare
part holdings for group owners with
multiple systems to maintain.
Maxiva Ultra-Compact and MultiCompact series are available for
multiple DTV standards, including
DVB-T/T2, ISDB-T/Tb, and ATSC,
with many input interfaces to ensure
complete, interoperable solutions for
any DTV network.
"We continue to evolve our Maxiva
solutions to ensure maximum
performance, flexibility, efficiency
and lowest total cost of ownership
for our customers as they build out
digital over-the-air networks," said
Rich Redmond, Chief Product Officer,
GatesAir. "Every network is looking to
streamline operations, and these two
distinct low power solutions simplify
network deployment and enable costeffective wireless content delivery."
On
the
performance
side,
cutting-edge echo cancellation and
optimised Modulation Error Ratio
(MER) performance far outperform
competitive solutions, drastically
reducing reception problems in
difficult reception conditions. The
exceptional MER performance is
especially important for low power
and gap filler performance, eliminating
imperfections tied to signal noise
and distortion. Translators can be
configured in two distinct ways: A
simple, zero IF, direct conversion
model; or a re-generative version that

GatesAir is extending the networking
capabilities of its VistaMax portfolio with VMXpress IP

The Maxiva Multi-Compact series comprises
high density, 4RU 19" rack-mounted UHF and VHF transmission systems

provides complete down-conversion to
baseband, together with re-modulation
to RF with full adaptive correction of
the signal. The re-generative version
provides the best solution for multihop scenarios, preventing progressive
signal degradation along the path. The
net result is a more robust received
broadcast signal for viewers, providing
optimum reception over adverse
terrain and viewing conditions.
The Connected Studio
On the radio side, GatesAir is
extending the networking capabilities
of its VistaMax portfolio with VMXpress
IP, an AES67-compliant audio and logic
device that establishes a standardsbased Audio over IP gateway for
radio studios. Leveraging the nonproprietary nature of ALC NetworX's
Ravenna networking technology,
VMXpress IP drives interoperability
across the studio and signal transport
architecture through its open,
standards-based foundation.
VMXpress IP evolves the robust
networking architecture of GatesAir
audio distribution and consoles,
seamlessly integrating with existing
and
emerging
AES67-compliant
devices to help broadcasters build
the optimal connected studio facility.
Using the tremendous flexibility
of open standards IP networking,
VMXpress IP simplifies connectivity
with audio processors, satellite
receivers, phone systems and studio
support equipment, including program
delays, among other key systems. With
GatesAir's existing network-based,
minimally-wired studio networking
architecture at the core, Ravenna's

networking technology fortifies the
overall infrastructure through low
latency distribution, and full signal
transparency. Overall, broadcasters
will enjoy a highly reliable and flexible
network to move audio and data
facility-wide.
Beyond the studio, VMXpress
IP extends networking to leading
IP transport solutions, including
GatesAir Intraplex IP Link codecs, for
low latency audio contribution and
distribution. This expands connectivity
to transmitter facilities (STL), live
remote broadcast sites, and the
Internet for streaming content to
other studios and the Web. Therefore,
the limitations of AES and analogue
connectivity are eliminated, instead
leveraging intelligent networking with
IP transport systems by using AES67
over the local Ethernet.
"With thousands of stations relying
on GatesAir's robust studio networking
solutions, adopting a standards-based
approach to the rapidly evolving
transition to IP is critical," said
Redmond. "VMXpress IP represents
our extension of GatesAir's robust
studio networking into this greater,
highly flexible, and interoperable
Audio over IP environment, simplifying
how our customers create, operate,
scale, and drive revenue within digital
studio facilities."
VMXpress IP continues GatesAir's
market leading strategy of using single
network-based connections (Cat5/6)
to move hundreds of audio and data
signals across a multipoint network,
ensuring a clean studio design that is
easy to deploy, operate, and scale as
requirements evolve.
