Magewell Unleashes Mac SDK for
Video Capture Solutions
M

agewell, the award-winning
developer of innovative video
interface and IP workflow solutions,
has expanded its support for the
Mac platform with a new SDK for the
company's popular PCI Express capture
cards and plug-and-play, external
capture devices.
Available immediately, the SDK lets
third-party developers directly access
the advanced capabilities of Magewell
capture devices in their macOS and OS
X software applications.
Magewell's USB Capture Gen 2, USB
Capture Plus and Pro Capture products
were already automatically compatible
with popular OS X and
macOS software through
native operating system
support
or
universal
drivers, but the new SDK
lets third-party software
vendors easily integrate
the
hardware's
rich
capture functionality into
their own solutions.

The SDK provides APIs based on the
macOS AVFoundation framework for
all three product families,
while custom Magewell
APIs for Pro Capture
PCIe cards enable deeper
control
over
capture
parameters, access to
ancillary metadata, and lower latency
for capturing video up to 4K at 60fps.
Example GUI-based and command line
tools help developers get up to speed
quickly.
"Windows and Linux programmers
have already enjoyed that our
SDKs make it faster and easier to

incorporate sophisticated
capture functionality into their
custom software, and we're excited to
bring the same advantages to macOS
and OS X developers," said James
Liu, VP of Engineering at
Magewell.
The new SDK for macOS
and OS X is available as
a free download on the
Magewell website at www.
magewell.com/sdk.
Founded
in
2011,
Magewell designs and
develops hardware and

software for video and audio
capture,
conversion
and
streaming.
With guiding principles of continuous
innovation and providing outstanding
customer service, Magewell has
earned a strong reputation for the
exceptional quality, performance and
reliability of its solutions.
Distributed
globally,
Magewell

GatesAir Upgrades Rocky Mountain
PBS Stations' TV Transmitters
O

wner of a statewide Colorado
network of PBS member stations,
Rocky Mountain Public Media has
purchased multiple GatesAir Maxiva
UHF transmitters and ATSC 3.0-ready
XTE exciters as part of an extensive,
multi-station upgrade.
The investment will improve
efficiency,
strengthen
coverage
and reduce maintenance across the
network's over-the-air operation,
and prepare transmitter sites for
next-generation IP-based content
management and delivery.
Rocky Mountain PBS, owned and
operated by Rocky Mountain Public
Media (RMPM), is taking a phased
approach to transmission upgrades
that will address the entire network
over several years. The first phase
was initiated through a repack project
for KRMA- DT in Denver, a 30kW
station, 100kW ERP, repacked from
UHF Channel 18 to 33. The Channel
33 assignment required a new
transmitter, with Rocky Mountain
PBS purchasing a Maxiva ULXTE-50

liquid-cooled model and a backup
UAXTE-6 air cooled transmitter,
transmitting at 3kW.
During the KRMA project,
station engineers also evaluated
vendor
options
for
several
other transmitter sites. Rocky
Mountain PBS exclusively selected
GatesAir Maxiva UAXTE air-cooled
transmitters for all additional
stations in the first phase, providing
station engineers with a common
high-efficiency,
solid-state
transmitter for each site. To date,
Rocky Mountain PBS has purchased
UAXTE medium to high power
transmitters for three full-power PBS
member stations, and low-power
UAXTE systems for several translator
sites. The translator sites deliver overthe-air programme signals across rural
areas of Colorado, and portions of
neighbouring states.
"Colorado's challenging terrain
and rural communities require
transmission equipment that is
powerful and reliable enough to

GatesAir Maxiva ULXTE at KRMA

maximise signal coverage, using
high-efficiency technology that keeps
our operations costs to a minimum,"
said Doug Houston, Chief Technology
Officer for Rocky Mountain Public
Media, Denver. "GatesAir's Maxiva
family also offers a broad range of
advanced options to serve all power
levels, ensuring a good fit for each
station's unique requirements. The

ability to remotely control each
transmitter and support IP content
delivery from our studios provides
greater value for our investment."
The
Rocky
Mountain
PBS
transmission equipment upgrade
coincides with the move of two
of RMPM's media properties KRMA-DT and KUVO-89.3FM radio
- to the new Buell Media Center
in downtown Denver. This threestorey,
multi-purpose
facility
houses studio and master control
facilities for these stations, along
with other local non-profit media
organisations.
Rocky Mountain PBS plans to
install an IP-based networking
platform to distribute TV content
to the KRMA transmitter site on Mt.
Morrison and build out similar IPbased connections to serve other
transmitter sites.
"The Rocky Mountain PBS upgrade
project is a prime example of the
versatility that GatesAir offers for
any broadcaster as we begin to move
beyond the spectrum repack," said Joe
Mack, Vice President of Sales, North
America, GatesAir.
