hifting demands in consumer
behaviour, portable devices,
streaming formats and
encoding standards have
raised the bar on what it takes to
compete effectively in the TV industry
and more broadly across the video
marketplace. Broadcasters and pay-TV
operators are accelerating their IPbased video services to compete more
effectively with over-the-top TV (OTT)
providers.
Keeping pace with these rapid changes in

allowing for the best architecture and

particular application, even if that
application changes over time. Support for
new services and video formats can be
integrated seamlessly through simple
software upgrades.
The Shift to Software in
Video Processing
Though fixed-function hardware may
continue to provide high performance and
good picture quality for specific applications
video providers can immediately respond to
changes in consumer demand. Support for
new features and standards can be added
through upgrades and API integration of
third-party software. Broadcasters and payTV operators who choose software-defined
video solutions don’t have to wait for new
custom video chips to be released to market,
they can continually update and enhance
their platform in line with increased
consumer demand and technology
advancements to create new revenue
generating video services. Ideally, a
Defining the Future of Video
technology and consumer demand is a
significant challenge to video providers.
Relying on traditional video processing
infrastructure is becoming increasingly
difficult and costly, yet video distributors
simply do not have the option of ignoring
demand for multiscreen video services as
they risk permanent loss of customers to
Internet-based OTT alternatives.
Within a highly fragmented technology
landscape, the return on investment of new
infrastructure purchases has become harder
to assess. Video providers who invest in
legacy technologies can find themselves
burdened with outdated equipment in need
of replacement. Choosing additional
infrastructure based on fixed-function
hardware might offer good performance
initially, but can be quickly surpassed by
more cost-effective software-based
approaches that keep pace with the
industry’s rate of change.
Software-defined video (SDV) solutions
offer a way around the trade-off between the
need for long-term investments in
technology for video delivery and the
expectation of short-term return on
investment. Thanks to Moore’s Law,
software running on general purpose
processors can now surpass task-specific
video processing equipment in terms of both
