nternational market research
fi rm Parks Associates recently
reported that a growing number
of consumers are using their
smartphone and tablet devices to
watch TV and use video apps.
In fact, 44% of tablet owners
and 32% of smartphone users
have increased their video
consumption on these mobile
platforms compared to 12 months
ago. Given the rising consumer
demand for high-quality video
content on every screen, today's
broadcasters must be equipped to
produce and deliver content for the
multiscreen environment.
Unfortunately, the current
video infrastructure is based
on bespoke hardware that
lacks versatility, elasticity, and
ease of provisioning, thereby
limiting broadcasters' ability
to adapt to the changing
business needs of multiscreen.
By embracing virtualised video
infrastructure (VVI), which unifies
previously discrete hardwarebased functions for broadcast and
multiscreen, broadcasters can
address current bespoke hardware
limitations concerning dynamic
resource allocation, scalability, and
flexibility. This article examines the
benefits and opportunities provided
by a virtualised approach to video
production and delivery.

Virtualised Video
Infrastructure
The purpose of VVI is to abstract
broadcast functionality from
the underlying hardware. With
virtualisation, broadcasters can
host functionality, such as media
processing, from a single software
platform across a number of virtual
machines. More impor tantly,
functions can be dynamically
assigned rather than permanently
assigned, as is this case with
bespoke hardware.
Unlike the limited capabilities
of fixed broadcast installations
based on bespoke broadcast
hardware, VVI enable broadcasters
to efficiently address fluctuating
demand based on capacity and

Migrating to V VI opens up
numerous oppor tunities for
broadcasters. First and foremost
is the opportunity to adapt to new
technology. We can all agree it
is hard to predict what is going
to happen in the multiscreen
environment. For example, there
are currently several packaging
and adaptive bitrate streaming
mechanisms (eg: Apple HLS, Adobe
HDS, Microsoft Smooth Streaming)

a next-generation protocol that
