3 3ETSI Starter Group on Digital Content Distribution July 7, 2008 DVB-IPDC in a Nutshell

4 4ETSI Starter Group on Digital Content Distribution July 7, 2008 DVB-IPDC in the DVB Context DVB handles multiple use cases of content distribution DVB-IPDC covers content distribution to mobiles xDSL DVB-S/C/T GERAN 3GPP/3GPP2 IP xMS A/V/D and signaling (ESG, DRM, …) Applications IPTV use cases Traditional TV use cases Cellular and Broadcast/Cellular use cases IP Mobile TV use cases IP DVB-T/H DVB-SH T-DMB DVB-T/H DVB-SH T-DMB Scope of DVB-IPDC

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

7 7ETSI Starter Group on Digital Content Distribution July 7, 2008 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

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

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

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

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

12 12ETSI Starter Group on Digital Content Distribution July 7, 2008 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

13 13ETSI Starter Group on Digital Content Distribution July 7, 2008 IPDC technologies impacted in 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

14 14ETSI Starter Group on Digital Content Distribution July 7, 2008 IPDC technologies impacted in 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

15 15ETSI Starter Group on Digital Content Distribution July 7, 2008 IPDC technologies impacted in 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

16 16ETSI Starter Group on Digital Content Distribution July 7, 2008 Meaningful Mobile SDOs in the scope of fix/mobile convergence

17 17ETSI Starter Group on Digital Content Distribution July 7, 2008 Meaningful Mobile SDOs 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

18 18ETSI Starter Group on Digital Content Distribution July 7, 2008 Meaningful Mobile SDOs 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

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

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

21 21ETSI Starter Group on Digital Content Distribution July 7, 2008 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? Shouldnt 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 SDOs to the benefit of all –Less technology fragmentation –Less resource fragmentation
