  6. Some use cases in fix/mobile TV convergence ETSI Starter Group on Digital Content Distribution July 7, 2008

  7. Why focusing on use cases? • They are essential to: • Make the link with business models, essential to justify the effort • Define clearly what to achieve • Define the role models and interactions, particularly complex in converging world ETSI Starter Group on Digital Content Distribution July 7, 2008

  8. TV programming TV programming TV programming Some use cases infix/mobile TV convergence • Terminal access to mobile TV services through mobile networks (DVB-H, 3G): Baseline IPDC use case 3G System IPDC DVB-xH System ETSI Starter Group on Digital Content Distribution July 7, 2008

  9. TV programming TV programming TV programming TV programming Some use cases infix/mobile TV convergence • Terminal access to mobile TV services from semi-static environment (home, office, hotspot, etc) Local network System 3G System IPDC DVB-xH System ETSI Starter Group on Digital Content Distribution July 7, 2008

  10. TV programming TV programming TV programming TV programming Some use cases infix/mobile TV convergence • Terminal access to fix (home) services from mobile environment Inter-connecting System Local network System 3G System IPDC DVB-xH System ETSI Starter Group on Digital Content Distribution July 7, 2008

  11. IPDC technologies impactedin fix/mobile convergence ETSI Starter Group on Digital Content Distribution July 7, 2008

  12. IPDC Technologies • IPDC toolbox currently allows for • ESG over broadcast and interaction networks • Content distribution over broadcast and 3G • Service purchase & protection based on OSF, 18Crypt and soon BCAST Smartcard profile • Mobility within DVB-xH networks and session re-selection over 3G • Fix/Mobile « convergence » are expected to bring new requirements on existing building blocks ETSI Starter Group on Digital Content Distribution July 7, 2008

  13. IPDC technologies impactedin fix/mobile convergence • Technology ingredients in current scope of IPDC that are impacted • ESG for the fix/mobile context • Evolved IPDC ESG toolbox should allow for: • Discovery of ESG and access over « local networks » • Aggregation from multiple ESG sources • Duplicate programming consolidation • One challenge to resolve is the Coexistence and/or convergence with other ESG specifications within the same environment (IPDC / BCAST, IPDC / IPI) • Extensions to support local (home) network specific content could/should be considered as well, particular to handle user content ETSI Starter Group on Digital Content Distribution July 7, 2008

  14. IPDC technologies impactedin fix/mobile convergence • Adaptation of IPDC specs for other IP bearers (eg Wifi) • Content Delivery Protocols (CDP) • Delivery profiles commonly available on identified bearers should be supported by IPDC terminals (eg RTSP profile) • Electronic Service Guide (ESG) • Instantiation of IPDC ESG in local network environment • Distributed ESG • « User-generated » ESG • Service Purchase & Protection (SPP) • IPDC SPP profiles in local network ETSI Starter Group on Digital Content Distribution July 7, 2008

  15. IPDC technologies impactedin fix/mobile convergence • Technology ingredients going beyond current scope of IPDC • Interworking with network domains • Discovery and authorization resolution to access « non-home » networks (sometimes known as « roaming » networks) • Media adaptation (e.g. format & bit rate adaptation) • Mobility support • Matching of similar services available in different domains • Media adaptation • « Seamless » handover ETSI Starter Group on Digital Content Distribution July 7, 2008

  16. Meaningful “Mobile” SDO’s in the scope of fix/mobile convergence ETSI Starter Group on Digital Content Distribution July 7, 2008

  17. Meaningful “Mobile” SDO’s in the scope of fix/mobile convergence • OMA-BCAST • Specified solutions similar to IPDC • Looking at extending use of BCAST specifications in IPTV context • Have BCAST Service Guide referenced in ETSI/TISPAN • BCAST IPTV vision seems not totally clear • Might be worth considering in context of IPDC/BCAST convergence ETSI Starter Group on Digital Content Distribution July 7, 2008

  18. Meaningful “Mobile” SDO’s in the scope of fix/mobile convergence • 3GPP • Started Work Item on « Extending PSS and MBMS User Services for Optimized Mobile TV Services » for Release-8 • Started Work Item on « IMS initiated and controlled PSS and MBMS User Service » • May be worth considering for 3G/DVB handover tools ETSI Starter Group on Digital Content Distribution July 7, 2008

  19. Meaningful “Mobile” SDO’s in the scope of fix/mobile convergence • IEEE • Has Study Item on DVB integration in 802.21 framework aiming at designing link layer capability for handover between heterogeneous networks • May be worth considering for DVB/IEEE802.xx handover scenarios ETSI Starter Group on Digital Content Distribution July 7, 2008

  20. Conclusions (?) ETSI Starter Group on Digital Content Distribution July 7, 2008

  21. Conclusions • Fix/Mobile convergence from IPDC perspective is a multi-dimensional problem • Technical • Are the current tool concepts are suitable for convergence? • How do we balance between convergence and coexistence of technologies? Shouldn’t the focus be on interworking? • How do we deal/liaise with relevant organizations? • Commercial • Which use case roadmap has to be considered for generating sensible commercial requirements? • Do we make the right balanced between the « traditional » TV and new TV paradigms? • How to ensure the right players are involved in this topic? • Marketing/Strategic • How to ensure that the right groups are doing the right things • How to liaise/cooperate with the relevant SDO’s to the benefit of all • Less technology fragmentation • Less resource fragmentation ETSI Starter Group on Digital Content Distribution July 7, 2008
