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

This Group’s 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

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

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

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

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 ?

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 ?

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, let’s 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

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
