NGN based IPTV
Designing decisions/functions
in actual non-NGN IPTV solutions
Aggregation – bringing together all the available content from where ever its available (satellite or terrestrial, direct from content providers)
Acquisition – authorization infrastructure for the acquired rights to distribute that content to your subscribers
Processing – processing the content into your defined format, MPEG2, MPEG4/H.264, VC-1, WM9 or combinations
Encryption – protect your revenue and the rights of your programmers
Middleware – include IPTV applications and services, web-like user interface, what your customer sees, their ability to personalize, navigate; their user experience
Distribution – making it available to your network – centrally or regionally
Network – multicast or unicast, and for how far
Delivery – your last mile into the home; utilize existing or a new deployment
CPE – choices, esthetics, marketability, delivery, installation, support

Personalization for Future Multimedia
Most of the end user usually really don’t care over which technology
we provide them the service, what they care: Price
Quality of service & reliability, support
Quality & Quantity of Content (TV channel portfolio, VoD assets, HD)
Usability (friendly UI) & feature and services
What they do not know yet but probably will want it when available: changing user experience – via personalization, quality, new services, mobility, user
interactions/networking, targeted services (Ad), multi-devices, more entertainment, tele(TV)
- services
The main goal of NGN based IPTV is standard based SP solution &
UE, integration with transport network, unified infrastructure for all
services (NGN & IPTV), user data for personalization,
NG-IPTV will provide new kind of services like integration with
communication services, user generated content, content
personalization, recommendation, personalized channels, FMC
continuation, etc. Source: IPTV World Forum 2009, Technical symposium

NGN based IPTV
General
characteristics
Non-NGN based IPTV
architecture
NGN/IMS based IPTV
architecture
Standardization Vendors & industry driven First NGN standards is in focus of standard bodies (ETSI TISPAN, ITU-T)
Modularity and
Open protocols
Low, alternative and proprietary protocols
Higher, standardized open protocols should be used (SIP, Diameter, …)
Media processing
and service
control separation
Functions are highly integrated in network elements and middleware
Separated service control from delivery and media control, should be more scalable, distribution on hierarchical base
Control functions Stream delivery control oriented Session control oriented – streams, communication sessions, ..
Transport control
functions
Missing specialized elements, less mechanisms to effect from application the transport control
Elements in the architecture for providing QoS (in TISPAN - NASS, RACS), IMS control resource mang.
non-NGN based vs. IMS based IPTV architecture

NGN based IPTV
General
characteristics
Non-NGN based IPTV
architecture
NGN/IMS based IPTV
architecture
Network
convergence
Specialized architecture for fixed or mobile network (more fixed oriented)
Common service and control layer independent from multiple fixed, wireless and mobile access & delivery networks
Application &
Services
More-less limited to legacy IPTV, however, set of services may be extended by adding interfaces to middleware
Real converged services as described in ITU-T converged service framework (broadcasting & communication convergence)
Service
Capabilities and
Enablers
No common service capabilities or service enablers, usually should be used just those included in IPTV application server
Shareable service enablers to support a number of more complex applications should be also available for IPTV related applications (messaging, presence,..)
Service
integration
Limited to each IPTV service platform
Possible across service layer of IMS based NGN architecture
Security Security covered more by CA nor DRM systems, different proprietary AAA mechanisms per solutions
Specialized border and security functions incorporate in standards, Security covered also on transport layer as well as content protection
End devices Limited number of STBs interworking with IPTV soultions
More standardized devices - integrated & compatible with IMS based IPTV

TISPAN cooperates with other SDOs to offer the right solutions
Our open system allows other SDOs / groups to build on our work
Active liaison relation with many related SDOs, groups and fora:
DVB, 3GPP, OMA, ATIS, ITU-T and many more
Reuse and cross-reference existing work, a.o:
Session and media control & delivery protocols from IETF
Service discovery and selection from DVB IPTV, OMA BCAST
and TV- Anytime
Common IMS, session transfer and Generic bootstrapping from
3GPP
Presence service from 3GPP and OMA
Remote management from Broadband Forum
Targeted advertising from SCTE and OMA MobAd
OIPF reuses and cross-references TISPAN service control protocols

IPTV Use Cases selected in Netlab
Use Case 3: DVB-H and IMS interconnection
The interconnection allows:
Enable to combine DVB-H broadcast delivery with
unicast delivery over mobile IP access (UMTS, LTE)
IPTV related streaming content and file based content
delivery
Service discovery and service announcement,
through unicast network, metadata delivery
QoS monitoring allows handover from unicast delivery
to broadcast delivery
Hybrid IPTV service with IMS
43 3rd Int NGN Workshop ngnlab.eu Eugen Mikoczy, 02.11.2011, Delft, Nederland
Prototype and standardization of hybrid models using
IMS and DVB-H (contributions to ETSI TR 182 030 )
Interconnection of IMS based IPTV systems and
roaming scenarios have been evaluated and advanced
use cases have been presented
Benefits
Vertical handover on different access networks, e.g. when point-
to-point access network is congested
More flexibility in service creation and delivery, e.g. user
generated content, interactivity features
Integrated Authentication, Authorizing and Accounting
mechanisms with NGN technologies
Hybrid IPTV service with IMS
Goals: Hybrid IPTV with IMS and DVB-H

50 3rd Int NGN Workshop ngnlab.eu Eugen Mikoczy, 02.11.2011, Delft, Nederland
Summary of benefits of standardized NGN based TV
1. Single architecture for Fixed IPTV, Mobile TV, hybrid SAT products
2. More TV services as any existing non-NGN middleware solution
3. Integration of NGN (converged voice, rich communication) with TV
services
4. Multi vendor, open environment, open interfaces, vendor-lock
prevention, interoperability/test
5. Integration to NGN transport control (QoS, resource reservation, lower
cost for network), common user profiles, integration to OSS/BSS
6. Application development, standardized browser
7. Standardized end devices and integration with home network
8. Content protection and service protection for FMC environment
9. Cost savings – CAPEX/OPEX for middleware, end devices, apps
development
10. Regulatory requirements

Service and architecture achievements by TISPAN
1. Most comprehensive set of services and features (over 40) – best state of art
2. Most simple architecture (compare to ITU-T, OIPF) with well defined interfaces,
functions
3. Most detailed protocol specification and implementation guidance for IPTV
4. Full chain of consistent IPTV specifications – architecture, protocols, security,
test spec, end devices
5. Most of the deployed NGN architecture for PSTN/ISDN replacement is based
on ETSI TISPAN R2
6. Fully compatible with DVB IPTV (non-IMS) or ETSI TISPAN NGN architecture
7. Show mapping of other standards to TISPAN (ITU-T, OIPF, 3GPP MBMS/PSS,
ATIS)
8. Support for mobile and hybrid scenarios, interconnection and roaming for IPTV
9. Integrated with user profile, transport control, content delivery infrastructure
10. ETSI special task force STF413 deliver TISPAN R3 test specification for
interoperability testing in June 2011

52 3rd Int NGN Workshop ngnlab.eu Eugen Mikoczy, 02.11.2011, Delft, Nederland
IPTV standards achieve required level needed for first implementation (2-3Y)
NGN/IMS became mature solution/standard mainly deployed for fixed voice
(replacement/innovation) but mobile and enhanced multimedia can coming
soon/later … (RCS, VoLTE, NG-IPTV)
NGN based IPTV can provide converged platform to deliver advance IPTV
services (not fully available in current solutions) but just time will show us if
TISPAN or other standards will be implemented (mainly because complexity)
New multimedia services like MMTel, RCS or NG-IPTV can leveraging of IMS
investment and previous operators experience
NGN/ IMS is only telco converged and standardized architecture for common
service control platform in transition period to Future Networks architecture
(beyond 2020)
Unmanaged networks and OTT technology will be extensively growing with
better and faster access networks (Internet of X)
Telco’s and Telco vendors should focus on industry advantages and provide
environment for new converged multimedia services
