All Rights Reserved © Alcatel-Lucent 2008, XXXXX 3 | Presentation Title | Month 2008 Scope and Use Cases 1
All Rights Reserved © Alcatel-Lucent 2008, XXXXX 4 | Presentation Title | Month 2008 Working Assumptions Convergence of IPTV and MobileTV Any use case where both have a role to play Implies interworking/interoperability between IPTV and mobileTV Problems well identified Many MobileTV standards in existence, many upcoming IPTV standards Defined as Silos without any interoperability path Convergence not addressed or very limited (e.g. within the silo) Technology islands, fight for supremacy, reduced services and content for each Many existing IPTV systems without any interoperability path Heterogeneous solution should be assumed (new common architecture unlikely) Content Offer without standard interfaces Content Distribution without standard interfaces
All Rights Reserved © Alcatel-Lucent 2008, XXXXX 5 | Presentation Title | Month 2008 This Groups Scope Transversal problems (spanning more than one technical solution) Convergence of IPTV and mobileTV : multi-screen Could cover interworking between iptvs and mobileTVs Content Distribution (applied to fixed networks, wifi, wimax, mobile,…) Facilitate timely content transfer from source to sink with efficient resource usage Use cases that cannot be addressed adequately in existing bodies Bodies centered on one technology or silo Bodies centered on specific constituencies or areas Problems that naturally span several bodies (content origination ?) Overall Goal Enable new uses and business models Enable more technical solutions into the game, including existing ones
All Rights Reserved © Alcatel-Lucent 2008, XXXXX 6 | Presentation Title | Month 2008 This Group Originality and Legitimacy Not betting on a given Technology Island or Silo Aims at providing interoperation between Existing technical solutions (DVB-IP, proprietary, DVB-H/SH/IPDC, OMA BCAST,…) Upcoming technical solutions (IMS,…) Consequences Must not make overly large assumptions on common elements or concepts (network…) Need to concentrate on higher level of abstraction Offers an interworking interface Technical solutions (products) can elect to support … or not
All Rights Reserved © Alcatel-Lucent 2008, XXXXX 7 | Presentation Title | Month 2008 Nonexhaustive list of possible Use Cases Transfer program from phone to TV (or Tv2Tv, Ph2Ph, sync or async) Common program production and formatting Cross-platform profile access and billing Cross-platform content access Cross-platform nPVR control and access PC access to IPTV/MTV « User experience » portability (not only video) Same program on all screens … What probably cannot be achieved (non goals) Same content protection, same management
All Rights Reserved © Alcatel-Lucent 2008, XXXXX 8 | Presentation Title | Month 2008 Example Use Case : IPTV-MobileTV session transfer John is watching soccer on his TV, must pickup wife at station Select « transfer program » in IPTV client Select « destination device » as « my mobile phone » - Signaling happens between IPTV system and MobileTV system - Phone client receives notification Asks confirmation, then displays channel with soccer program IPTV system MobileTV system Mobile Network i/w i/f Internal i/f

All Rights Reserved © Alcatel-Lucent 2008, XXXXX 12 | Presentation Title | Month 2008 Content Distribution Proposed Goal Enable timely distribution of content from source to sink with efficient resource usage Motivation Distribution not always efficient, or timely (especially from internet) Possible Subjects Content provider interface Content Distribution interfaces P2P or not P2P : why, where ? An implementation issue ? Content Protection impact ? PVR in content distribution ?
All Rights Reserved © Alcatel-Lucent 2008, XXXXX 13 | Presentation Title | Month 2008 Convergence in *TV Proposed Goal Enable interoperation between *TV systems and support specific use cases Motivation Convergence not specified outside of Silos Possible subjects Billing, Profile access Cross system notification, program correlation Support of rich content guides ? …
All Rights Reserved © Alcatel-Lucent 2008, XXXXX 14 | Presentation Title | Month 2008 A word on Content Protection Many competing technical options in the marketplace OMA DRM, DVB CA, DVB CPCM, Marlin,… Huge dispute, not going to be settled here, lets avoid the debate Potential to be a significant roadblock for many use cases Some of it technical, some of it business models What is remaining ? Impact of content protection aspects on some use cases –Opacity of transmitted content (no access to I-frames,…) –Per-session encryption impact on caching DRM extensions to support right export/import ? Defining key roadblocks to use cases –Use as a tool for CP solution selection ? Define required support for richer business models, ultimately provide it ? –Not selecting business models, but enabling –Ultimately decision belongs in business partners

All Rights Reserved © Alcatel-Lucent 2008, XXXXX 16 | Presentation Title | Month 2008 Working with others Partnership is key This initiative threatens many other organisations They claim a similar scope with their SILO Must avoid competition to avoid creating ANOTHER solution Must talk to stakeholders in different IPTV and MTV organisations (DVB, TISPAN, OMA, OIPTVF, ATIS IIF, ITU-T IPTV GSI, 3GPP,…) Must defer to others when this makes sense Same use cases, same operational constraints and features in same environment When work programme is realistically more timely
