4K Capabilities
Video Clarity is a provider of market-leading
audio and video quality measurement
and analysis systems...

A

t IBC2014, Video Clarity is
launching ClearView Shuttle
4K, a new system that adds
another 4K capable solution to our
ClearView video quality analyser
line.
Originally designed as a portable,
entry-level
solution
for
HD
video quality-of-service testing,
ClearView Shuttle now includes
record and playback capabilities
for testing 4K output on devices

Video Clarity's ClearView Shuttle 4K provides recording
& playback testing of network endpoint devices.

designed for network endpoints,
such as set-top boxes and tablets.
With the ability to record and
play back a single sequence
of uncompressed 4K video,
ClearView Shuttle is ideal for
device manufacturers as well as
media operators who need to test
new encoding technologies and
existing process devices already
installed in their operations.
Video Clarity's ClearView
Version 8.1 software interface.

Maintaining Quality
To maintain video and audio
quality as compression standards
change, everyone along the
broadcast chain needs to measure
continually the performance of
the compression engines on
which their day-to-day operations
depend.
And now, as more and more
devices with 4K capabilities
are built and deployed, device
manufacturers as well as operators
require quality testing with the
ability to record at native 4K
resolutions in addition to HD and
SD formats.
ClearView Shuttle 4K is an
evolutionary step that provides 4K
I/O device and signal path testing at
a lower price point with repeatable,
objective quality measurements
that closely resemble subjective
results.
Frame-By-Frame Results
ClearView Shuttle 4K is a small,
lightweight, and portable device
that can be used easily on a
desktop or moved from the lab to
an office environment if required. In
a typical workflow, the ClearView

Shuttle 4K records the 4K source
reference video (or an imported
4K file) and then plays back the
sequence at up to 60 Hz in realtime.
The analyser calculates the
segment's video quality score and
provides frame-by-frame results to
enable a qualitative picture quality
evaluation.
Any operation, large or small, from
hardware and software designers
to end-user producers who work
with any kind of compression in
standard or high definition, should
analyse compression performance
to know how their technical and
aesthetic choices will look to end
users.
With ClearView Shuttle 4K, we've
made it easy and cost-effective for
product R&D and QA departments
to accomplish this for 4K material.
It's one more example of how
Video Clarity is continuing to drive
quality delivery of 4K video and
bring new 4K testing features to
market as quickly as we can.
We will demonstrate ClearView
Shuttle 4K at the IBC2014 show.
Please come by for a first-hand
look at this new system.
