Video Clarity At IBC2016
A

head of IBC2016, Video Clarity
will launch a new colour transfer
function in the ClearView line of video
quality analysers.
ClearView can apply Rec. 2020
appropriately to the different colour
formats and colour conversion
techniques being considered for high
dynamic range (HDR) content. In this
way, content providers, broadcasters,
and encoder manufacturers can
compare the quality of HDR source
content against its downstream
encoded version, no matter which
colour space or conversion technique
is applied.
Another colour format under
consideration is ICtCp, a potential
replacement for the YCbCr colour
space that could provide better
encoding performance downstream
when working with compression
schemes such as HEVC. Facilities can
use ClearView to ingest video, record it
in either YCbCr or ICtCp, and compare
it to encoded versions in either YCbCr
or ICtCp for significant changes in
quality. Users can activate the colour
transfer capabilities in ClearView and
select among different colour formats
with simple button presses.
With
these
colour
transfer
capabilities, which follow SMPTE
ST 2084 and ITU-Rec. BT.2100, the
ClearView system is taking another

step toward accommodating
every aspect of the wider
colour gamut in use with HDR
content. The ICtCp addition
will be available at IBC2016 in
September.
MultiPlayer
At IBC2016, Video Clarity
will demonstrate MultiPlayer, an
optional application for new and
existing Video Clarity ClearView 4K
systems. MultiPlayer is the only such
product that can automatically and
interactively select sequences for side
by side playback in multiple video
formats on up to eight screens at
once. MultiPlayer can output up to
four different HD or SD video playback
sources from a ClearView Analyzer
4K or ClearView Player 4K system
with a single quad HD-SDI interface.
In ClearView 4K systems with two

quad HD-SDI interfaces, MultiPlayer
can play up to eight HD sequences
or one 4K sequence plus four HD
or SD sequences, all with audio and
in several combinations. Users can
control each sequence playback
individually or lock all sequences to
one command. They can also apply a
fixed side by side view to each output,
which enables additional comparison
between the source and encoded/
decoded versions of video on all
screens and outputs.
Programme originators and product
developers can use MultiPlayer to
study the effect of different video
resolutions and/or bit rates on video
quality. They can also perform a visual
study of 4K versus native HD playback
or HD formats that are played on 4K
monitors.
ClearView WFM
Making its European debut at
IBC2016, Video Clarity's ClearView
WFM is a new software option for
ClearView Video Quality Analyzer
and ClearView Player systems. To
complement the colour-space and
HDR capabilities introduced in the
latest ClearView update (ClearView
8.4), ClearView WFM actively reads
and tests any imported or recorded
video file to help users understand
input or output signal parameters as
generated by waveform, colour vector,
and chromaticity charts. ClearView
WFM provides ClearView users an
integrated,
affordable,
effective
means of displaying signal parameters

- upon either input or playback -as
a graphical representation on the
desktop, and it eliminates the need for
external signal-measurement tools.
RTM 4K
Finally, IBC2016 visitors will see
RTM 4K, a 4K-capable version of
the company's RTM real-time audio
and video monitoring solutions. In
a technological milestone for the
industry, RTM 4K is the first qualitymonitoring solution that can apply
4K video sources and compare them
with encoded/decoded 4K video to
test for video quality, audio quality, lip
sync, and loudness. It is also the first
to perform those tests in real-time,
providing the full-reference MS-SSIM
perceptual quality metric on the DMOS
scale.
The 3-RU RTM 4K is built with a
variety of applications in mind, such
as testing new 4K HEVC encoders for
audio and video performance over
time, and testing the performance of
origination channels and automatically
recording and logging faults in video,
audio, lip sync, and loudness. Content
providers can also deploy RTM
4K - both in advance and during a
broadcast - for long-haul performance
testing of special large-audience live
programming, or in any instance
where 4K content quality monitoring
and measurement are required.
