some of the key trends for 2018. 4K video over the internet? The end of SDI broadcast?
What are your business plans These things were unthinkable a decade ago. In fact, the TV industry was quite

and cybersecurity? But a fully digitized TV industry – still very young compared to the industry’s 90
year history – is enabling rapid, accelerated change, and the obscure acronyms of
a few years ago are ping-ponging around in every conversation you hear.
We hope this report will give you a good grounding in what is happening with
some of the game-changing technologies in the industry, and hopefully give you
an edge in strategizing how you are going to use them.

flexibility to access content no matter what they watch and where they watch it.
Bridging the technological gap between on-demand OTT content and live linear
broadcast hasn’t been easy. A few solutions have come to market, such as tun-
ers that can be plugged into a laptop via USB, or satellite services like SAT>IP that
allow a uniform satellite TV experience across multiple devices. But turning your
tablet into a true OTA capable TV has been technologically more trouble than it’s
worth. The alternative has been live streaming services, which broadcasters are
increasingly offering – but without much additional revenue in return.
“Most viewers really don’t care about the technology. They’ve got a
display in their hand. They want to watch in bed when they get up, then
have their viewing continue while they’re having breakfast and still be
able to have a discreet peek at work.”

apparent to us at SMPTE some years ago, but it’s only now that it has really come
in.“ Weitzel points out that the transition to IP is fraught with more challenges for
the TV industry than for other industries that only require commodity IT.
One theme that has been woven into every broadcast industry
conference, trade show, publication and webinar in 2017 is IP. The “IP Revolution” may grab trade magazine headlines, but the industry is being
careful and deliberate about how it proceeds.
Broadcasters are embarking on a major transition from SDI connectivity,
dominant since the 90’s, to operating fully in the IP realm. “We do have some special requirements,” notes Weitzel, “including synchroniza-
tion and easy movement of very large files. The whole issue of IP splits up into so
many different parts.”
“A definite tipping point has been reached. It was apparent to us at As we move through this transition phase, we see many case studies touting

David Smith points out that the transition may have some growing pains. “With
the old SDI system, you had to plug a cable into port xx on a router and then
somewhere on the network management system you have to type in that port xx

logging system to make the equipment talk to each other. And you still have to do
that with IP at the moment. Carrying uncompressed 4K video over IP is also un-
wieldy. It is easy enough to do with quad 3G-SDI or 12G-SDI, but a 10 gigabit link
doesn’t have enough bandwidth to carry uncompressed 4K video, and a 25 giga-
bit link is going to be an expensive option for the next few years.”
SMPTE ST 2110, which describes the application of IP within a broadcast studio,
is a work in progress. The carriage of video and audio over IP was finalized during
IBC 2017, but other parts of the standard are still being defined.

The switch from SD to HD was also a switch from analog to digital, which was
both a technological and qualitative leap. A leap from HD to 4K would just turn up

or the equivalent of digital arson. Who is doing what and with what motive can
become increasingly obscure in the digital jungle.
Every company that handles valuable content and information nowadays is a
potential target for cybercriminals. In media and entertainment companies, the
content is the key asset and every theft, damage or crime can be hazardous for
business.
In 2015, French network TV5 was taken off the air by Russian hackers pretending
to be ISIS. Sony’s series of major data breaches was blamed on North Korea, but
many have pointed to a source within the company itself.
The movie image of a chain-smoking hacker typing in secret passwords to gain
access to some digital treasure chest is now being replaced by sophisticated algo-
rithms and bots that can target and overwhelm many systems simultaneously as
well as well-educated, sophisticated organizations that may have state or corpo-
rate backing.
“There is no typical cyberattack. The variety of damage that can be
inflicted ranges from information capture, piracy, ransom, privacy data,
corporate and governmental espionage and even terrorism to using
hacking tools for simple boundary testing. And many attacks happen
from within an organization.”
Helko Koegel, Director of Consulting for cybersecurity at Rohde & Schwarz.
