piracy experience as frustrating as possible.”
“Because all devices are connected, the
reason people will attack devises will change:
people’s viewing history and personal data
may be vulnerable, an operator may be
vulnerable to
ransom
malware and
denial of
service
attacks.
They’re low

impact if they
occur. So

will be IP.”
“With live events, of course, the main
piracy is in re-distribution. We are
constantly monitoring for pirate streams and
the first line of defence is take down notices
with the ISPs. In the World Cup this had an
effectiveness of 50 to 60 per cent in real or
near real time and we constantly work on
those relationships to improve that. The
other approach is to watermark and monitor
and identify the source
of the illegal stream and
shut it down.”
“Unfortunately we
often see, particularly in
OTT, that the usability,
presentation and video
quality of pirate streams is actually very
good; it’s often comparable to locally
available pay-TV services. This is the real
threat to services in the long run. The
“Make your
service as
compelling
as possible”
Using the data OTT delivers
access metadata around content to
give a common look and feel across all
the different devices the user can
access the service on.”
“I think speed to market for TV
Everywhere is very important, even if it
means fixing up a few problems afterwards.
This is because a key driver for piracy is if
you don’t have a solid service offering.
Certainly in security it presents a new
paradigm. Before it was all about
making sure the smart card wasn’t
hacked. Now there are different
threats; the re-broadcast of
content – that’s definitely a big
growth area, the other area is
attacks on the unmanaged devices
used in TV Everywhere.”
“This is where you need a managed
security solution. There will always be
multiple DRMs and I think we are showing
that’s quite possible to cope with. Some of
the standardisation that is coming – like
MPEG-DASH and the common container
format - will help, it holds the promise of
encrypting once and then using multiple
DRMs for the same piece of content.”
“What we feel is becoming more
important is managing the complexity
around DRMs and around the piracy
management - we know content is going to
leak and it is a more complex problem to say
where is it leaking, how is it leaking, what
monitoring and forensics, when it comes to
devices it is less about content and more
about other services that are going through
those devices.”
“Smart homes, home automation, brings
that vulnerability into the home and the
crucial thing is to think about it in terms of
Internet security – how you lock down
devices; a lot of work now is about how you
can embed security modules inside devices
which are providing real time
monitoring and real time access
control at a software level. So, if
