NRK Speeds Transcode Workflows
Norwegian Broadcaster NRK relies on Telestream’s Vantage platform for speed and efficiency...

RK is the national broadcaster
in Norway. In addition to its
headquarters in Oslo, it has 18
other locations around this very
large country. To minimise the
bandwidth required to transfer
content unnecessarily, each of the
regional centres has an extensive
technology platform, including a
subset of the broadcaster’s asset
management platform, based on
Omnibus technology.
One of the challenges facing NRK,
in common with many broadcasters,
is the need to transcode digital
content between different file
formats, codecs and wrappers.
This includes the necessity of
converting external content to the
house standard on ingest and the
ability to deliver content over multiple
platforms to meet the requirements
of its audience, which is now used to
accessing the broadcaster’s content
on different devices.
NRK had been using Telestream
FlipFactory for transcoding for
several years, but recognised that
they now needed greater productivity
and simplified, highly-automated
workflows. In addition to simple
transcodes, the broadcaster wanted
to implement other processes
into the same workflows, such as
inserting graphics tuned to the
requirements of the destination
platform, and replacement of online
content for which NRK does not
have the intellectual property rights.
Given the experience with
FlipFactory, NRK looked at
developing a new transcoding

platform based on the Telestream
Vantage system. Working with
Norwegian distributor Video4, NRK
established that the rich feature set
in Vantage met their requirements.
With support from the Telestream
technical team, they designed and
implemented the new platform.
According to NRK system
administrator, Jarle Igeltjørn, the
system now has instances in each
of the 19 centres, with the largest
installation in Oslo. In total there are
47 Vantage licenses, of which 20 are
hosted on Lightspeed servers, the
dedicated GPU-powered servers
developed by Telestream to provide
the maximum power for Vantage
processing, including delivering
the best image quality in the least
amount of time.

Egil Ljøstad, Head of File-based
Production at NRK Technology,
described the scale of the
requirement. “We have a broad range
of requirements, from simple file
moves to complex workflows where
we convert, make adaptive bitrate
files, cut content and superimpose
graphics, all in one workflow. We also
accept content from our audience

Roald, and Jarle Igeltjørn

and automatically convert it to
our house format. In short, we do
almost all of our conversions in the
Vantage system.
“In our main installation in Oslo
we have about 70 active workflows,
which routinely process up to 700
encodes in a single day,” Ljøstad
explained. “We have seen as
many as 1,500 jobs in a day, but
that is rare.”
Workflows are largely initiated
automatically, either on demand by
the Omnibus asset management
system or, in the case of content
arriving at NRK, by the Signiant
content exchange software. The
broadcaster can also initiate
workflows manually using a drop
folder system. They normally avoid
this, but sometimes circumstances
dictate the need for this direct access.
Where graphics need to be added–
which can include a full-screen
caption to cover content removed
for rights issues–then the Omnibus
system initiates their creation in
either Vizrt or Chyron hardware.
An NRK-developed web service
application automatically sets up in
and out points, or durations, for the
graphics insertion as part of a single
pass through the Vantage transcoder.
One of the key reasons for moving

to the new Vantage platform with
Lightspeed servers was to boost
throughput. For the online service
tv.nrk.no, the platform must create
five different adaptive bitrate
versions of each piece of content.
NRK set a goal of producing all these
versions within 1.5 times the content
running time, and with Lightspeed
acceleration the system achieves
this comfortably with margin to spare.
In addition, the broadcaster is
now able to use software standards
conversion between HD and SD
on incoming content, something
that was not possible before due
to quality concerns. Vantage
meets the broadcaster’s technical
specifications, as well as offering the
operational simplicity of including
it as just another workflow on the
standard platform.
“We designed the system and the
workflows ourselves, which was
what we wanted to do,” added
Ljøstad. “But Telestream was there
to help us from the beginning, and
whenever we needed them we
could just call.
“For us, moving from FlipFactory
to the Vantage platform was a big
success. And with the investment in
Lightspeed Servers, we gained even
more speed.”
