LTN Global Agrees To Acquire Crystal
LTN® Global enables end-to-end managed
broadcast operations, transmission, and content
monetisation...

L

TN® Global has entered into an
agreement to acquire Crystal, a
provider of software that automates
the monitoring, control, and metadata
management of end-to-end broadcast
and digital media operations.
Together, LTN and Crystal will offer
mission-critical ad insertion, digital
watermarking, and other unique tools
that will allow networks and digital
platforms to monetise their content
across a fully managed IP multicast
network.
"Over the past three decades,
Crystal's
customised
software
solutions
have
provided
a
management and control backbone
for the world's leading broadcast,
cable, and satellite networks," said
Malik Khan, co-founder and Executive
Chairman at LTN Global. "Now, LTN
will integrate Crystal's innovative
technology into our software-managed

IP production and transmission
workflows. This integration allows our
customers to leverage the power of a
managed network to greatly reduce
high CAPEX costs and puts essential
content monetisation tools at their
fingertips."
By combining forces, Crystal and LTN
solve one of the most pressing issues
faced by video content distributors the RF spectrum consolidation caused
by the advance of 5G that results
in a reduction of valuable C-band
satellite capacity - the bedrock of TV
distribution.
LTN lays claim to be the only fully
managed IP network offering a "five
nines" or greater SLA to its customers
alongside the content customisation
and control solutions of Crystal.
Crystal's patented technology signals
key data from all traffic, scheduling,
and playout systems consistently

through any delivery platform,
including OTT, CTV, and TVE.
The integration of Crystal technology
into the LTN portfolio brings customers
the benefits of working with a common
GUI across key services, NOC support
for the end-to-end workflow, and
scalable workflows that leverage LTN's
data centre resources.
"Crystal's goal is to be a ubiquitous
element
across
a
network's
distribution chain, providing the
mission-critical ad signalling and
marking associated with all of the
current and emerging MVPDs and
vMVPDs," said Crystal CEO Roger
Franklin.
"By joining forces with LTN, Crystal
now has the ability to transport these
properly marked video feeds with fully
managed reliability and latency and in

any required format."
Crystal's AdConnect software is
in high demand. Currently, over
100 linear networks have deployed
AdConnect to provide customised
digital markings to OTT platforms.
Crystal is adding an average of
five new networks every month as
content owners and distributors
face an increasing number of unique
monetisation challenges.
The company's technology enables
TV ad inventory owners to sell
advertising on an addressable basis
on any platform, whether delivered via
Over-the-Air to smart TVs (e.g. Open
Addressable Ready, OAR), traditional
distribution, or OTT.
