Tektronix Helps Content Creators
Solve Critical Challenges
N

ew technologies such as
4K, Wide Colour Gamut
(WCG) and High Dynamic
Range (HDR) allow video
content creators to create
stunning images and content
for delivery to the home, but
they also add considerable
complexity to workflows.
Tektronix has unveiled
a comprehensive set of
production tools to help
content creators minimise
and manage this complexity at its
source - the camera.
In live environments, there is often
a mix of HDR (High Dynamic Range)
and SDR (Standard Dynamic Range)
cameras used. When using traditional
waveform monitors to balance these
cameras the different trace levels
for the same luminance levels forces
operators to do a lot of guess work
as they try to balance the cameras.
In studio or episodic production

PRISM gains a 4K/WCG/HDR toolset

environments, there is a high cost
associated with scene setup and
luminance levels, therefore, operators
and DP's need quick and consistent
ways to set lighting using displays
that provide measurements and levels
that have a direct correlation to the
relative light levels (Stops), rather
than percentage scales available in
traditional waveform displays. In
addition, matching colours and skin
tones across different colour spaces

(BT2020 and BT709) is
challenging when producing
content in multiple formats
which means operators need
familiar displays (such as
BT709 Vector display) that
enable them to make these
checks quickly and accurately
across colour spaces.
As
a
software-based
platform, PRISM offers a
range of options and fieldinstallable
upgrades
for
monitoring hybrid IP/SDI networks
among many other applications. With
the addition of the new 4K/WCG/
HDR toolset, PRISM now becomes a
comprehensive production solution
that includes:
*	 A
Tektronix-patented
Stop
Waveform
Display
that
allows
operators to adjust camera exposure
in a consistent manner without having
to worry about the optical to electric
transfer function (OETF) of a camera.

It also allows cinematographers
shooting episodic dramas to quickly
create scene or subject lighting, saving
production time and expense.
*	 An industry first vector display
with a 3D LUT that allows the familiar
BT.709 vector to be used to evaluate
skin tones, match colours to familiar
reference marks and determine the
degree of colour gamut compatibility
for BT.709 conversion. Because
operators can stay in their comfort
zone even when working with different
colour systems, the vector display
helps to create high-quality content
without error and reduces the learning
curve.
*	 A combination of full, quad
or vertical display modes that give
operators extensive flexibility to view
application displays optimally for
their needs and thus maximise their
efficiency.
Available in 3RU half-rack, 1RU fullrack and standalone configurations,
the PRISM platform along with the new
production toolset will be available at
the end of September.

Kaltura Pledges High Availability
Cloud TV Service
T

he new release of the Kaltura
TV Platform ensures 99.995%
availability for live and VoD TV viewing
across all devices - the first in the
industry to commit to this level of
service, Kaltura is well positioned
to provide IP based Cloud-scale TV
solutions to large operators and media
companies worldwide.
"The TV viewing experience is
literally changing before our eyes,"
says
Shay
David,
Co-Founder,
President and General Manager
of Media and Telecom at Kaltura.
"Kaltura provides customers with
Cloud-scale TV services, with marketleading availability of "four and a half
9's", along with full flexibility to offer
a variety of end-user experiences, all
managed in a single platform, which
can seamlessly integrate with legacy
STBs and platforms that have been
heavily invested in."
David continued: "As large-scale live
TV events are increasingly streamed

over the Internet, operators simply
can't afford any glitches - just imagine
experiencing buffering just before
the final goal of a football match.
Kaltura sets your mind at ease. With
our Tier-1 global deployments and
market-leading technology platform,
Kaltura is uniquely positioned to
guide customers along their Cloud TV
transformation."
Additional
enhancements
to
Kaltura's TV Platform include;
*	 Marketing Campaign and Coupon
Engine - operators can now upsell new
TV products and special offers to their
customers through a dynamic coupon
campaign engine.
*	 Personalisation based on user
interests - users can select their
favourite content, and as a result,
enjoy a more personalised service with
more relevant content. Users will even
receive notifications when new content
that matches their specific interests
becomes available.

Modular:
Kaltura's TV Platform

*	 Churn prevention capabilities
- operators have a full toolkit to help
prevent churn. Kaltura's system
proactively measures user "happiness
scores", and churn predictability -
service providers can then send out
notifications and create dedicated
marketing
campaigns,
including
configurable discounts and coupon
codes.
*	 Search Enhancements - a search
history enhances the Kaltura search
experience by allowing end users to
retrieve previously searched queries
for fast lookups; as well as Soundex
search, which adds language-based

"fuzzy" search capabilities.
Kaltura has invested
heavily in the modularity
of its platform, allowing
customers
to
experiment with a
range of business
models, and other
features
and
functionality,
on
their journey to
finding the optimal TV solution for
their needs.
The platform's flexibility also
enables Kaltura to integrate with
legacy TV platforms and migrate
them to a hybrid Cloud solution so
that customers can still benefit from
their previous investment in STBs and
infrastructure while moving to the
Cloud.
The latest Kaltura TV Platform
release
includes
a
slew
of
features geared towards end-user
personalisation,
and
enabling
operators to market to and reach their
users in a more targeted, user-specific
way.
