Transition to Remote Production

Events, Remote Production
Workflows Are Here to Stay
Reducing the massive expense of
producing live events has long been
a goal for many executive producers
and organizations. The sheer costs
involved in transporting large teams
and equipment to remote locations
have been a driving factor to find
ways to streamline workflows that
could do more with less. Tried and
true methods are slow to change,
so the
remote evolution plodded
along even though new technology
innovations
existed
overnight,
and
that
support these types of changes.
Almost

the COVID-19
pandemic caused remote production
workflows
models
to become crucial to ensuring that
" the show must go on. " Sending
fewer staff into the field had tangible
safety benefits during the pandemic,
and
this
forced the industry
innovate new ways
to
to streamline
processes and collaborate. As the
pandemic wanes and more staff
are protected, it's clear that many
remote production workflows
are
here to stay - they are simply less
expensive to deploy and operate.
For example, NBC sent a relatively
small staff to Beijing for the recent
Winter Games. Content was

This is clearly a reflection of " the
new normal, " which will continue
to evolve at live events around the
world.
Smart IP Technologies
Pave the Way
The latest IP technologies have
been key to enabling the transition
to remote production workflows

The next technical challenge is to
reliably send large, camera-original,
media files over the internet

is high and parallel redundant paths

and RIST (Reliable Internet Stream

However, it takes much

The large, expensive, mobile
production vehicles with their
crew and equipment won't be
disappearing anytime soon.
But the model is changing and
adapting. No longer does every
event require a full complement
of operators and infrastructure.
An IP-based remote production

Standards
like
ST 2110 and IEEE 1588 (PTP) are
becoming critical to onsite success.
This
represents a significant
reduction in capital expense. Couple
that with the savings realized by
reducing onsite staff, and we see
exactly the business shift that was
driving the evolution, albeit slowly,
pre-pandemic. Remote production
is now enabling broadcasters
to
migrate their media workflows
beyond
hardware solutions of the past
expensive, inflexible
to
an agile, pay-as-you-go model that
other technology sectors have long
benefited from.
Remote Automated Media
Ingest/Capture
For live events, sophisticated live
capture devices can be deployed onsite
that capture full resolution, highquality
media in the format required
by
editors
while simultaneously
creating low resolution, highly
compressed proxy versions. These
files are typically
transferred into
a shared cloud bucket or to onprem
storage where editors have
immediate access to them. The realtime
transfer of growing files enables
remote editors
to engage in the
creative process even while video is
in the process of being captured.
For

from the
format, such as
50Hz material that must be converted
to 29.97/59.94Hz, additional
compute-intensive processing in the
cloud or on premises may be required
depending on the workflow. Since
it is essential to always process the
media where it resides, an intelligent
hybrid
processing workflow that
supports both cloud and on-prem
processing paths ensures maximum
value. And as more media flows
through the cloud, available compute
power can support even the most
intensive processing tasks, such as
frame rate and HDR/SDR conversions
when necessary. Automating the
creation of all these media versions
and
ensuring they
are instantly
is
available and linkable by
the
editors is critical to the success of
any remote production.
Monitoring for Quality
Remote production workflows
rely on media transported
that
over the public
internet can be
blind to problems that might occur
to the content being transported.
This is true for both live media

quality is through a technique called
" monitoring by

software is tasked with validating
stream content, timing correctness,
and network health automatically.
Coupled with in-depth diagnostics
instruments like a modern waveform
monitor/network

it comes to file quality, the ability
to QC large master quality files can
be a challenge if media is stored in

consideration when
