Improving Automated Intelligence
In the rapidly evolving world of transcoding, improving the efficiency of the core engines is key...

here are any number of ways
to improve efficiency but
automated encoding/ transcoding
engines and virtualised workflows
are top of the tree.
Virtualisation, or the decoupling
of plant-based hardware for IP
delivered and software resources, is
transforming many aspects of video
broadcast services.
Cloud encoding, for example,
helps lighten the load of point of
broadcast equipment and hardware.
This enables studios to focus on the
more classical aspects of quality
broadcast such as lighting and
sound, rather than worrying about
extra layers of encoding hardware
at the point of broadcast. Likewise,
the virtualisation of delivery enables
a studio to send out a single stream
and deliver to many device targets.
“Gone are the days of running
and maintaining multiple encoder
software for different ingestion
servers for different delivery targets,”
says Michael Dale, Senior Director
of Product at Kaltura. “Now a single
broadcast stream is ingested in the
cloud, repackaged and encoded for
OTT devices connected to HDTVs,
all the way down to phones with
smaller screens running different
operating systems that require
different delivery protocols.”

Senior Director of
Product, Kaltura

“…Gone are the and
days of running
maintaining multiple
encoder software

”

For optimising resources, the
overall trend towards virtualisation
cannot be understated: it enables
broadcasters to successfully string
together a seemingly impossible set
of software services in the cloud,
rather than be constrained by locally
managed, end-to-end delivery.

Virtualisation Benefits
Virtualisation can help in outsourcing
live video transcription; resource
scaling based on demand; global

CDN-backed adaptive streaming
and DVR; robust motorisation
options; ease of switching to other,
non-normalised geographically
dispersed ingestion streams;
and seamless ‘live to Video on
Demand’ delivery.
Discussions of virtualisation
almost always include the cloud,
but it’s not all just about using
external processing resources. For
many of Digital Rapids’ large media
customers, the model’s value starts
in-house, and extends outwards as
an “elastic extension” of on-premises
capabilities.
“In-house cloud dynamics can
help address the investment and
total ownership cost concerns of
new projects or expansion while
enabling resources to be allocated
and deployed dynamically in quick
response to demand,” explains Mike
Nann, Director of Marketing. “The
ability to ‘spin up’ new software
resources to expand capacity asneeded using existing underutilised
infrastructure, or to automatically
reassign the functionality being
performed on a computing resource
on-the-fly, lets organisations
maximise their efficiency and
resource utilisation.
“Of course, for those looking to
expand their capacity beyond their
facility walls, the cloud enables
elastic resource expansion without
the capital expenditure and timeconsuming effort of provisioning of
additional local physical systems.
This enables organisations to quickly
scale up to handle new initiatives or
short-term peaks in demand with
minimal investment and risk.”
According to Benoit Fouchard,
CSO, Ateme, virtualisation will
primarily deliver efficiencies by
decoupling the infrastructure from
the events and personal resources
that use them.
“A good example of this is remote
production, where infrastructure can
be utilised more efficiently if it can
remain in a central location rather
than be onsite in a truck because the
down time related to transit can be
saved,” he says. “The same applies
to people who will not need to travel.
So virtualisation will allow efficiency
in workflows, deeper specialisation of
human resources, a more flexible and
scalable platform and overall very
significant economies of scale and

savings on resources that are today
under-utilised in broadcast facilities.”
Envivio is seeing a big shift from
dedicated transcoder appliances
to software-based compression
running on servers in datacentres. In
this case, running a variable number
of transcoding instances on virtual
images can bring big benefits in
areas where processing needs are
fluctuating over time.
Benefits include offline filebased processing where number of
instances can be adjusted according
to the volume of files and the
processing speed required; and in
live events where particular events
might require more linear transcoders,
(e.g. specific sports event with multicamera views, specific shows etc.),
and additional virtualised instances
can be launched during the event.
Specific editing might also be
required and launched at that time.
“There is definitely an opportunity
for broadcast facilities to consolidate
all the applications which are not
running 24/7 on fewer servers,”
predicts Boris Felts, VP Product
Marketing, at Envivio. “This will
rely on the presence of efficient
and optimised software which is
capable of replacing hardwarespecific products, something Envivio
has been deploying for years. It will
also need virtualisation – a mature
technology that has been deployed
successfully for years in the IT
space. Finally it will require efficient
job management and scheduling,
again something that exists today
in the IT world, but might need to
be adapted to take into account the
broadcast facility constraints. We are
also working on this.”

Automated Analysis
The trend toward virtualisation which
was very apparent at IBC2013, is
inextricably linked with that of
another big trend - Big Data. Having
greater data about processes,
bottlenecks within workflows,
usage trends of various systems
- and more importantly, deriving
operational insight from that data

– enables virtualised resources to
be automatically reallocated to
maximise efficiency.
For example, Digital Rapids’ Kayak
workflow platform can automatically
adapt the running workflow on-thefly based on continuous analysis of
metadata and results from previous
processes, says Nann. From a
business standpoint, both the
gained insight itself and the resulting
ability to optimise resources lead to
cost savings, he suggests. “Better
resource utilisation means fewer
resources that the user must invest
in to achieve their job requirements,
while better insight allows them
to ensure during project planning,
that they can continually meet their
capacity requirements without overspending and over-provisioning.”
While some customers see offline
storage and transcoding as an
obvious direction, these tending to
be operators who actually own the
content that they distribute, others
are more concerned about security
during transfers and processing.
“These tend to be the customers
who distribute other companies’
product, and are worried about the
liabilities they face should the product
be pirated while in their care,” says
Paul Turner, VP, Enterprise Product
Management, Telestream.
Tools such as these can automate
management of material and
performance of repetitive processes,
freeing up creative personnel to be
able to focus on creation of new
content. Products like Telestream’s
Vantage transcoders can “intelligently”
create multiple versions of the same
material for distribution to various
consumption platforms.
Explains Turner: “Vantage’s
ability to actually look at the video
inside a file can alleviate the need
to have a human being inspect
elements, and allow the system to
make judgements based on a set
of rules, progressing the media
through the most appropriate
workflow, again without the need
