Presentation by Dirk Jaeger, CTO - Divitel, on Sep 8, 2012. This installment of the Multi-network Solutions in the Real World Forum series discussed real-world examples of multi-network video rollouts from across Europe. It was offered on-site during IBC 2012, with the goal to break down the technical and business challenges that operators face with multi-network services.

3. Paradigm changes
 Multiple Service Operators: network operators
offered an increasing portfolio of dedicated
services (TV, Internet, voice, mobile, …)
 Full service provision: provider attempts
integrating all applications to a single service
 Next OTT ?
 Will finally global content players provide their services to
a global society?
 National, regional, and local elements will continue to be
important for customers
 Information, news, services, contacts etc.
 OTT provides opportunities for enrichment of service
offering but is not a new paradigm

4. Experience based on customer
requirements
 Global communication & community services
 International & local content
 Diversity of & infinity access to services
 Content provision and network operation are
orthogonal businesses
 Regional networks hamper MSOs for global content
provision
 QoS: service consumption in best possible quality
 Multi-/heterogeneous- network solutions optimized
for provision of rich media services

5. Heterogeneous Network
Architecture – basic layout

Managed (e.g. SAT) users
Service with
Providers multiple
e.g. devices
Managed (e.g. SDH) e.g.
Central Managed (e.g. Cable,
+ Broad-
point WiMAX, 4G)
caster Unmanaged (e.g. + TVs
e.g. HE
+ ISP Internet) + PCs
+ OTT + Tablets
+ „Smart‟
Unmanaged (e.g. Internet) devices

6. Multiple networks
 Managed networks
 QoS mechanisms available at different layers of transport
system need to be aligned to service requirements
 Unmanaged networks
 No opportunity providing adequate QoS mechanisms for
transport
 Varying QoS parameters: delay, BER, bit rate etc.
 Signal needs to dynamically adapt to current network
conditions for best quality
 Technologies: adaptive robustness, adaptive bit rate
coding etc.

9. Summary
 Media world is evolving
 OTT will potentially change the medial environment
 Services to travel through multi- and heterogeneous-
networks
 Well established platforms to serve customers‟ needs
 “Inter-technology” knowledge for system integration
 Good partnership with leading manufacturers
 Open standards
 Technology is available, however, good business ideas and
commercial experience fundamental for successful service
launch and operation
