Avoiding the pitfalls of modern
IP broadcast workflows
A
voiding the pitfalls of modern IP
broadcast
workflows requires
modular, software defined and
virtualizable solutions.
It's easy to get caught up in the need
for the next, best, newest, shiniest
technology, and as the broadcast
industry leaves the tried and tested
world of SDI behind, IP is the next stop
in its evolution.
While SDI's days are far from over,
an IP-based infrastructure has shown
itself capable of delivering faster
and cheaper ways of creating highvalue
content. It opens the way for
new possibilities, such as remote
workflows, support for many more
cameras and the ability to easily
handle uncompressed 4K. IP-based
infrastructures
offer the greater
flexibility and capabilities that
broadcasters need to compete in a
market where disruptors, such as
Netflix and Disney+, are shaping the
landscape.
A key concern expressed by
customers is how to make the
transition from SDI to IP workflows;
do you integrate them together,
create a hybrid model connecting one
to the other, or do you make the big
leap to a pure IP infrastructure. Many
broadcasters also question whether
they will make that big step to IP
only to find they should have moved
straight to the cloud.
However, switching out SDI for IP
- whether your end game is to go all
in or choose a hybrid model - is just
one step in the process, and there are
pitfalls to be wary of along the way.
Changing how content is
created and delivered
One of the traps that broadcasters
can fall into is believing that moving
into an IP world will in itself change
everything. Broadcasters need to
be
thinking
about
the
flexibility,
scalability and remote capability that
IP enables and redefine the art of
making and delivering content.
Undertaking the transition from
SDI involves so much more than
just moving to an IP infrastructure;
you need to be thinking about how
you actually create and deliver your
programming from beginning to end
and how you need to redefine your
working model where staff, regardless
of their function, can be located
anywhere - even their own homes -
when needed.
delivery mechanisms. Migrating to IP
requires a change in mindset across
the whole organisation. What you
don't want is a situation where you
have invested in flexible, scalable
IP infrastructures but continue
to replicate old ways of working.
Everyone from technical to creative
staff must adapt to the more agile,
smarter approach to content creation
and delivery that IP enables.
Before they even look at
implementing IP, broadcasters must
also consider whether they are aiming
to deliver services via OTT, to mobile
devices, and whether they are looking
at 5G Broadcast, ATSC3.0 and so on.
In short, how are they going to create
new worlds for the consumer and how
will an IP workflow help enable that?
Staff then need to be trained so they
can switch over to this new IP-centric
world and maximise the power that IP
puts at their disposal.
Thinking in software
from the start
A major
pitfall
A good illustration of the above is
remote working, which is the goal
for the majority of customers now.
The need for, and the value of, full
remote workflow capability has been
thrown into stark relief by the global
pandemic. This showed us all just how
critical modular, software-defined and
virtualizable IP workflows are, but also
underlined the basic fact that you can't
virtualize a system if it's not software
defined, and nor can you virtualize it if
it's not IP-based.
Only in a software-defined world will
you get the flexibility to add and delete
new features, add new standards, and
leverage the power and flexibility of
IP to quickly switch to remote working
capability, where employees can be in
any location.
that
many
broadcasters have tripped over is
believing that all IP is created equal;
they move to an IP workflow only to
find it isn't virtualizable. Hardware
can't be " softwareized " , you have to
be thinking - from scratch - in software
right from conception.
Before the pandemic, we were
preparing for disaster scenarios
where you would simply move staff
from one location to another and pick
up operations from there. Nobody
imagined that you wouldn't be able
to access the back-up location!
Traditional broadcast hardware-based
playout environments cannot operate
hands-off - they need people. The
benefit of IP workflows built around
remotely accessible servers is now
very clear to us all. It gives you the
power to flip the disaster recovery
system and turn it into a remote
At Rohde & Schwarz and Pixel
Power, we have been strong advocates
of building production or playout
workflows from modular software
components, sitting on standard COTS
(commercial and off the shelf) IT
hardware, right from the beginning.
This gives you a degree of disaster
recovery protection that is as close to
perfect as you can get; broadcasters
can rapidly pivot their set-up and have
operators working remotely, from
home whenever needed.
Having this type of IP capability in
place lays the groundwork for a future
move to virtualized playout from a
private or public cloud, or having the
primary playout on premise, with
disaster recovery in the cloud and
anywhere, anytime accessibility. It's
vital to understand that if a system
isn't virtualizable, being softwaredefined
doesn't really mean much.
Deeper engagement between
customers and vendors
Right across the board at Rohde &
Schwarz and Pixel Power we offer,
and have done for some time, a
professional services toolset that
allows us to work with each customer
right from the moment they have the
idea that they need to overhaul their
infrastructures and workflows.
We've
been
doing
this
for
broadcasters all over the world, so we
have a good view into how you need to
approach the concept creation in the
first place, because we know what's
possible now and what's going to be
possible over the next couple of years.
We also have a deep level of expertise
in working with these customers right
from the moment they decide they
want to change their workflow through
to the ongoing support over the
following years.
System Integrators still have a
key role to play in the partnerships
between manufacturers and end
users. The more interesting SIs have
shifted their approach away from
the old " rack and stack " model and
become facilitators, bringing different
manufacturer's software solutions
