Hybrid Live Video Services Delivery
A hybrid architecture delivers the economic benefits of the
cloud while ensuring the broadcast-grade performance argues
Eric Gallier VP of Marketing, Thomson Video Networks...

T

he challenges of live video service
delivery affect every broadcaster
and network operator, and live video
networks are required to satisfy
customer expectations in many
diverse, if not conflicting, ways. With
pressure to deliver premium video
quality to any screen, from HDTVs to
tablets and smartphones, operators
are looking for solutions that free
them to concentrate on the business of
designing differentiated services.
This means technologies and
systems that can automatically handle
such complex tasks as resource
provisioning, load balancing, and
redundancy in a simple and efficient
way, with the ability to scale and
protect the operator's investment in
the face of fast-paced changes in the
ecosystem.
These disruptive changes mandate a
new type of architecture. Reacting to
the effervescence of today's live video
networking landscape, some operators
are tempted to adopt a restrictive
technology scope. Such an approach
might meet today's most immediate
needs, but will certainly lead to
structural dead-ends in the future.
Instead, we propose a much broader
approach - a hybrid architecture that
mixes on-premises and cloud-based
resources to support both broadcast
and multi-screen services.
In a hybrid cloud architecture for live
video delivery, operators can deploy
services on video-optimised hardware
or using software-based encoding
running on lower-cost and generic
physical servers, virtualised servers
and cloud infrastructures.
