The Evolution Of File-Based QC
utomated QC is evolving.
Once considered primarily
for standalone islands of artifact
detection and viewing, modern
QC software is a more integral
part of the broadcaster's workﬂow.
File-based QC is bringing more
benefits across the broadcast
chain. So what is it that has helped
move QC products forward?
Smart Plans: Being able to plan
QC activity with no surprises is
becoming fundamental to content
providers. Discovering ﬁle types
that are not supported and not
applying the optimum tests based
on the ﬁle source are real issues.
Modern QC solutions feature tools
allowing for incompatible files
to stay out of the downstream
workﬂow and to apply the correct
test template to the incoming ﬁle,
based on the ﬁle attributes.
Analyse More: QC solutions
must achieve a higher throughput
of ﬁles, often using the power of
multiple CPU cores and utilising
the GPU to achieve outstanding
performance, and must be easily
scaled for increasing volumes of
ﬁ les. Modern QC solutions can
process 4K video at real-time
with HD content pushing 4x faster
than real-time. Modern software
architecture in QC solutions should
allow for constant job performance,
ensuring that additional ﬁles added
to the QC system do not impact
performance, regardless of file
type or tests.
Review Faster: QC is only a
good investment if it delivers
significant efficiency benefits.
Legacy QC workﬂ ows typically
deliver manual review times of
two to three minutes per issue by
lacking frame-accurate review links
between the QC system and an
externally provided software player.
Modern QC solutions allow for
review times to be cut substantially,
making the review process up
to eight times more efﬁcient, by
offering frame-accurate review
players with annotation capability.
Integrating human-based review
and automated QC can accumulate
the entire QC process into one
XML-based report to be used
for downstream automation or
customer delivery. Standardised
QC test deﬁnitions, provided by the
EBU QC group, ensures a common
vocabulary between operators
and QC systems.
Ta k e S m a r t e r A c t i o n s :
Traditionally it has been a
manual process to take the ﬁ le
through the correction process
after QC. Modern QC software
though can now help make that
action happen, either directly
or by enabling smart decisions
in automation systems. The QC
software itself should be able to
automate simple processes such
as moving the ﬁle to a particular
location, or provide more advanced
controlling of applications
such as performing loudness
normalisation or integrating with
third party software for cropping
out letterboxing, removing bars
and tones, or API integration with
archive or automation systems. The
FIMS effort within AMWA should
make such integration even simpler
in the future.
File-based workflows are
clearly providing advantages over
linear workﬂows by accelerating
throughput and content availability.
Legacy QC software can provide
adequate analysis, but it can also
hinder the rapidly expanding
workﬂow beneﬁts available with
modern QC solutions. Workﬂows
are evolving, and modern QC
vendors are providing evolutionary
systems to meet that need.
Omnitek Teams With Semtech For 6G-SDI 4K Technology
ne of the novel items revealed
at the 2013 IBC show was
the prototype of a 6G-SDI Input/
Output module, developed by test
and measurement manufacturer
OmniTek in collaboration with
Semtech Corporation, a leading
supplier of analogue and mixedsignal semiconductors.
The 6G-SDI module is an FMC
card which mates with OmniTek's
new OZ745 Zynq SoC-based video
development kit (which was
also on display).
The OZ745 is a unique tool for video
engineers that enables complex
algorithms to be prototyped using
the power of the latest Xilinx
XC7Z045 Zynq SoC devices.
OmniTek's 6G-SDI card offers
two SDI input channels, two
SDI output channels, and a
DisplayPort 1.2 input and output.
The SDI input and output channels
feature two of Semtech's Gennum
Product Group's 6G-SDI interface
devices: the GS6042 in the input
channels and the GS6080 in the
The inclusion of the Semtech
interface devices in the SDI
channels allows the card to provide
full coverage of all four standard
SDI bit rates: 270Mb/s, 1.485Gb/s,
2.97Gb/s, and the new 5.94Gb/s
rate (including the /1.001 variants).
The new 6G-SDI I/O channels
mean that the OmniTek FMC card is
The dual 6G-SDI 4K Input/Output module was on show at IBC in OmniTek-Semtech collaboration
compatible with both 4K x 2K @ 30p
images using one 6G channel, or 4K
x 2K @ 60p using dual-link 6G-SDI.
The DisplayPort 1.2 channels
also support 4K x 2K @ 60p for
connections to the latest ﬂat panel
displays and projectors.

Hodson said: "There is a deﬁnite
groundswell of interest in higher
resolutions and higher frame-rates
from broadcasters, ﬁlm-makers,
cinema-goers and the like which
is driving a signiﬁcant growth in
demand for 6G-SDI.
"This has in turn created a
demand for a 6G test and
"I'm happy to say that Semtech's
technology is enabling OmniTek
to address a critical gap in the
marketplace by being first-tomarket with a 6G-SDI test and
