DESCRIPTION

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.

  • 1. The 8. International Conference on Advances in Mobile Computing & Multimedia (MoMM 2010) 8.-10. November 2010 Paris, France

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 8.-10.
