This paper evaluates the existing NGN based IPTV architecture and services in the context of IPTV service personalization within multi-user environment at home network and user equipment. Advanced scenarios of IPTV for providing fully personalized and interactive IPTV services using existing and new mechanisms in Converged NGN based IPTV architectures are proposed within this paper. The services can improve the quality of experience (QoE) and user expectation via new personalized IPTV service behavior. Presented at MoMM 2010 in Paris, France.

Mobile Computing & Multimedia (MoMM 2010)
8.-10. November 2010

2. } The need for personalization
} IPTV Architectures in NGN
◦ NGN integrated IPTV
◦ IMS based IPTV
} Converged NGN based IPTV
} Personalization in IPTV
} ngnlab.eu implementation
8.-10. November 2010Sebastian Schumann / MoMM 2010 2

3. } Broadcasting television (TV) channels is
where it all started
} Tele text added in the late 70s
◦ Text information on TV screen
◦ TV Guide
} TV sets got extended by set-top-boxes (STB)
◦ In the beginning only signal conversion
◦ Later on access to premium/pay TV
} Video recorder and DVD player/recorder
enabled off-broadcasting content
8.-10. November 2010Sebastian Schumann / MoMM 2010 3

4. } Digital TV and evolution in TV sets and STBs
enhanced the experience of television
◦ Extended TV guide
◦ Recording w/o medium (video cassette, DVD)
◦ Time shift
◦ "Trick mode" (pause TV, play back, chase play)
◦ Video on Demand (VoD) like services
} "Integrated back channel" from viewer /STB/
to broadcaster provided by IPTV
◦ Real video on demand
◦ Recording from the internet
◦ Interactive services, applications
8.-10. November 2010Sebastian Schumann / MoMM 2010 4

5. } P.: "to make personal or individual"
(m-w.com)
} "P. involves using technology to accommodate
the differences between
individuals." (wikipedia.com)
} Problem: Television nowadays is not
personalized
◦ No integration of personalized services
◦ No Web 2.0 integration
◦ General: No integration in systems that distinguish
between users and not only customers
8.-10. November 2010Sebastian Schumann / MoMM 2010 5

6. } Personalization requires from the system a
full understanding of the
◦ users
◦ services and
◦ content
} It can be achieved only if the system can
identify its users
} User interface presentation, services and their
behavior, content recommendation, search
and content presentation has to be adapted
8.-10. November 2010Sebastian Schumann / MoMM 2010 6

7. } TISPAN IPTV services in R2 not personalized
◦ Entertaining (trick modes, pay per view, VoD)
◦ Advertising
} TISPAN R3 new services and NGN interaction
◦ User generated content, recommendation,
bookmarks
◦ Targeted advertising, profiling and personalization
◦ Watching apart together, presence, call
management
◦ Content sharing, device switching
8.-10. November 2010Sebastian Schumann / MoMM 2010 7

8. } Broadcast TV
◦ presence, profiling
} Content on Demand
◦ profiling, recommendations, (presence)
} Personal Video Recording
◦ presence status dependant recording
8.-10. November 2010Sebastian Schumann / MoMM 2010 8

9. } Service enabler
} Basic services usually use presence to
observe the actual state of the service
◦ current channel
◦ state of VoD and watched content
} More advanced integration needed to
aggregate information not only by UE updates
but also directly from IPTV functional
elements
◦ internal state, service state or service action data
8.-10. November 2010Sebastian Schumann / MoMM 2010 9

10. } Interactive TV
◦ Interactivity between user and provider
◦ Presence identifies users, profiling suggests scenarios
} User Generated Content
◦ Sharing content
◦ "Discuss" it with online parties
} Content Recommendation
◦ Advisory based on user behavior
◦ Presence, profiling
8.-10. November 2010Sebastian Schumann / MoMM 2010 10

11. } Content bookmarks
◦ Markers in user profile
} Targeted advertising
◦ Target group or individuals based on behavior
◦ Profiling, grouping
All mentioned points require the identification
of the actual user behind the TV set.
8.-10. November 2010Sebastian Schumann / MoMM 2010 11

12. } NGN based IPTV first improvement of limited
proprietary solutions
◦ Standardized control and media delivery
◦ UPSF, RACS/NASS
} NGN IMS based IPTV with unified service
control
◦ IMS core replaces IPTV service control components
◦ IMS based services can be integrated
} Both concept allow basic personalization
