disguise and ROE Visual partner to advance
extended reality and virtual production
n 2020, disguise launched its awardwinning
xR workflow that allows
creative and technical teams to render
photorealistic graphics content from
engines like Unreal Engine on LED
surfaces developed by companies like
ROE Visual. With the help of camera
tracking technology, these graphics can
then be displayed in-camera as realtime,
3D, photorealistic environments
that immerse actors, artists, presenters
as well as the audience watching in a
whole new world. This technology from
disguise and ROE Visual has many use
cases, with the most common being in
TV broadcasts, films, fixed installations,
corporate and entertainment events.
disguise technology powers more
than 300 xR stages in over 45
countries with many powered by ROE
Visual LED.
I
Both ROE Visual and disguise
workflows have featured as an integral
part of hundreds of immersive and
real-time
productions
around
the
world including TV Azteca's coverage
of the 2020 Tokyo Olympic Games,
Billie Eilish's Where Do We Go live
streamed concert, the 2020 League of
Legends World Championship esports
event, Nissan's Thrill commercial,
Walmart's 2021 YBM and ICM virtual
events, Kaskade's hybrid concert in
Fortnite and Rocket League, and Katy
Perry's iconic performance at the 2020
American Idol finale - a performance
widely acknowledged as the first major
live broadcast to use extended reality.
With both companies' trusted
reputation for groundbreaking
technology that power some of the
greatest productions, the newlyannounced
partnership aims to
further enhance the development of
game-changing technology
to
equip
the virtual production studios of the
future.
The partnership will see ROE Visual
LED solutions powering the expansion
of disguise offices around the world
with
immediate
effect,
including
disguise xR stages and innovation
'hubs' launching in Beijing, Seoul, New
Zealand and Hong Kong towards the
end of this year. In addition, disguise
will employ its xR workflow, including
vx media servers and the rx range
of render nodes, to run ROE Visual
showrooms in the Netherlands, the US
and Japan - with the project kicking off
in the last few months of 2021.
Through this joint collaboration
and partnership, both companies
will leverage each other's technical
knowledge, innovations and customer
feedback to refine and guide their
respective product roadmaps to
ensure customers have the highest
quality technology.
The partnership is a reflection and
extension on disguise and ROE Visual's
long-standing relationship dating
back to 2017 when disguise began its
research and development into xR
workflows. Since then, disguise's xR
stages in its London and Los Angeles
offices have u-sed ROE Visual LED
volumes exclusively.
Both companies share a customercentric,
service-orientated approach.
The extensive user groups from
both ROE Visual and disguise will
feed valuable customer insight into
creating the next generation of virtual
production technology.

Dielectric Drives Breakthrough in AI-Based
Directional FM Antenna Pattern Verification
D
ielectric has changed how FM
broadcast antenna manufactures
validate directional pattern studies
for new FM broadcast antennas.
Dielectric's groundbreaking research
resulted in the recent FCC filing of a
Petition for Rulemaking, written with
leading broadcast consultancy, Merrill
Weiss Group, and expected to be
approved this fall.
The new rule paves the way for the
first directional FM pattern verification
rule change in 58 years - a rule change
that passes the torch from physical to
AI-driven simulated modeling. Merrill
Weiss, principal of Merrill Weiss Group,
offered his expertise on existing FCC
rules while assisting with the writing
and filing process.
The inspiration behind Dielectric's
effort is to provide FM broadcasters
with a more efficient and economical
antenna modeling process. FM
broadcast antenna manufacturers
today build physical models and
collect measured data to verify
antenna patterns - a time-consuming
and burdensome process. Dielectric's
petition
proposes
that
the FCC
allow FM antenna manufacturers to
transition to computer-based antenna
modeling using
computational
methods - an approach widely used in
other broadcast products. In fact, this
technique has been used for TV station
antenna modeling since 2017.
" This is simply long overdue, "
said Dielectric's Vice President of
Engineering, John Schadler. " FM is
the only FCC service that still requires
a physical range measurement, and
anyone who has worked with range
measurements knows that accurately
measuring radiation patterns is
extremely difficult. Simulated pattern
verification is much more economical
with less chance of error - it just makes
sense. "
The clearance to leverage simulated
antenna modeling will also result in
better accuracy for broadcasters.
" 3D high-frequency simulation will,
in many ways, yield results that
are
superior
to traditional
HFSS model vs scaled model in range
measurement proofs, " said Schadler.
" Since simulations are done in a true
free space environment, any issues
with the range or anechoic chamber
and with the surrounding environment
are eliminated, resulting in more
reliable azimuth patterns and H/V
ratios. "
range
The use of software also eliminates
the lengthy set-up and take down time
of models, as well as the need for a
technician to adjust the model and
take data points by hand. This removes
mechanical tolerances and human
error affecting the data. Another
