infrastructure.
By using both ground and cloudbased resources, video providers
can fine-tune the balance between
CAPEX and OPEX in deploying
video processing capabilities. In
many cases, providers may keep
core video processing and delivery
in an appliance-based deployment
with cloud-based resources
handling spikes in demand, testing
of new services and providing
system redundancy. Virtual
machines can be allocated for video
processing and delivery tasks
alongside other business
applications like CRM and
BSS/OSS. As processing and storage
capacities of cloud infrastructures
improve, video processing can
benefit from increased performance while
legacy hardware can then be re-purposed for
less computationally intensive applications.
Software-defined video solutions
minimize system downtime as upgrading or
enhancing a codec or feature involves a
simple software update or upgrade.
Underlying hardware does not need to be
switched out and software instances can be
re-assigned to standby units or cloud-based
resources to assure continual service. For
example, the manner in which softwaredefined H.264 and HEVC video processing
can share off-the-shelf and cloud-based
processor resources can greatly mitigate the
risks associated with a new service launch.
Adding New Multiscreen Capabilities
As the number of consumer viewing devices
and video formats continue to multiply, video
providers need to keep costs under control
and streamline management of their
broadcast workflows by consolidating their
video processing and delivery systems. On
the content delivery side, whether over cable,
satellite or the Internet, this means moving to
IP-based video technology including HTML
video and adaptive bitrate streaming formats
such as HLS and MPEG-DASH, allowing for
universal support across multiple types of
devices such as smart TVs.
IP networking enables
distributed storage for
greater levels of content
backup and redundancy,
over internal infrastructure
as well as commercial cloud
services. The IP standard
also allows for more
efficient transport of video
from broadcast studios, to
head-ends, and local edge
all sorts of advanced features and
capabilities to be fully integrated
into a single unified system.

With software defined-video, live-to-VoD
features such as nPVR and catch-up TV can

more flexibility and scalability. In dedicated
