DVB-IPDC in a Nutshell


DVB-IPDC in the DVB Context• DVB handles multiple use cases of content

distribution

• DVB-IPDC covers content distribution to mobiles

Some use cases in fix/mobile TV convergence


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


Some use cases infix/mobile TV convergence

• Terminal access to mobile TV services through mobile networks (DVB-H, 3G):

IPDC technologies impactedin fix/mobile convergence


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



• 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



– 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



• 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


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



• 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



• 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


Conclusions (?)


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
