3 DAIDALOS /18 Outline DVB Summary DVB-H Survey Results on DVB-H Hybrid Networks Why integrate DVB into IEEE How to Integrate Conclusion

4 DAIDALOS /18 D igital V ideo B roadcasting DVB Initiated in 1991 for digital TV More than 260 broadcasters, manufacturers, network operators in over 35 countries Currently more than 150 million DVB receivers are in use Traditional broadcasting (TV Channels) over different media types DVB-C (able) DVB-S (atellite) DVB-T (errestrial) DVB-H is based on DVB-T standard but designed for small, portable devices like Mobile Phones. Optimized reception in mobile environments through new modulation and error correction mechanisms (better signal quality) By the use of time-slices is perfect suited for small, battery- powered devices

5 DAIDALOS /18 DVB-H DVB Transmitter 1- Up to 40 km coverage 2- Around 40 channels with 300kbps 3- Unlimited number of receivers 4- Supported by over 60 manufacturers

6 DAIDALOS /18 DVB-H Mobile TV with DVB-H has been tested in more than 40 countries 7 countries launched commercial services Finland, Italy, India, Albania, Philippines, Vietnam, Nigeria Other countries are planning initial services for 2008 (Germany, Russia, Spain, USA, UK…) Example United Kingdom (Arqiva - Oxford) : 85% satisfied customers, 72% willing to pay for the service within 12 months 37% of usage while commuting to and from work An average of 24 minutes of view per session / 4 hours per week Traditional TV programs more attractive than made-for-mobile content Customized and interactive services are demanded such as video Blogging

7 DAIDALOS /18 IP Datacast DVB was initially designed for Digital TV reception One-to-many unidirectional connections No Interactivity, passive TV watchers MPEG2 streams No IP, no other service IP Datacast Developed by the DVB CBMS (Convergence of Broadcast and Mobile Services ) Working Group Enables traditional IP based services over DVB Defines service enabler for broadcast services Purchase, Service Description, schedule and acquisition… Supports the integration of cellular networks as service enablers Return Channel

9 DAIDALOS /18 Convergence World of Broadcast World of Telecom

10 DAIDALOS /18 The missing part In the following years we will dominantly witness services using hybrid networks Devices capable of UMTS, DVB-H, WLAN… are already there For a common user interface an interactive mobile TV standard with a media independent Java API (JSR 272) is also there Open Mobile Alliance (OMA) Mobile Broadcast Services Enabler Suite (BCAST) Open Mobile Alliance Supports DVB-H, 3GPP MBMS, 3GPP2 and mobile unicast streaming systems at the application layerDVB-H3GPPMBMS3GPP2unicast Interaction with other technologies at the network and data link layer is missing IEEE is currently the best candidate to fill in this gap! Different than other networks: Hybrid Networks fundamentally need cooperation among existing technologies hence need IEEE more than others

11 DAIDALOS /18 DVB and Handover Intra-technology handover for DVB is already defined Inter-technology handover reasons given in the current draft are also true for DVB deployments QoS concerns, service availability, mobility, price, power management, network selection… Some handover scenarios: Especially in suburban and intra-urban areas handover between DVB and UMTS/WIMAX is needed Automobiles equipped with DVB - UMTS- WIMAX already being tested by some manufacturers Price issues might foster use of WLAN when available In case of service unavailability on a specific DVB network choose UMTS or Wimax

12 DAIDALOS /18 How to Integrate IEEE assumes bidirectional connection Information can be exchanged between peer MIHF entities This is not directly possible for DVB Needs an uplink channel for bidirectional connection Communication with own MIHF is possible in all cases Integrate unidirectional DVB

13 DAIDALOS /18 MIH Reference Model for DVB-H MIH Event Service MIH Command Service MIH Information Service Media Independent Handover Function (MIHF) MIH-SAP Layer 3 or higher Mobility Protocol (L3MP), Handover Policy, Transport, Applications MIH-DVB-SAP DVB Device Driver MPE Has two parts: MIH related information from DVB transmitter MIH related information from DVB interface Program Specific Information/Service Information (PSI/SI) Electronic Service Guide ESG MPEG2 Higher layer

14 DAIDALOS /18 Integration of DVB DVB Interface MIH Function DVB Network MIH Function MIH User

15 DAIDALOS /18 Integration approach A study group should work on definitions of MIIS information elements for DVB MIES and MICS parameter mapping/definitions for DVB definition of MICS, MIES, MIIS interfaces between drivers of DVB and IEEE recommendations for DVB driver implementations

16 DAIDALOS /18 Next Steps Further discussions within IEEE and DVB Formation of a study group (feasibility analysis) Analysis and evaluation of compatibility Unidirectional Connections Definition of parameters Definition of interfaces to MIES, MICS and MIIS Preparation of implementation recommendations Consider integrating bidirectional DVB-H Definition of requirements Definition of bidirectionality related parameters Definition of new primitives and protocols if needed Implementation recommendations

18 DAIDALOS /18 Conclusion Hybrid Broadcast/Mobile Networks composed of 3GPP and IEEE technologies have significant financial advantages for all mobile network operators Initial mobile TV services using hybrid networks in different countries have shown that customer acceptance is very high We will witness more and more hybrid networks in the following years Hybrid Networks need more cooperation among different technologies than vertical handovers do IEEE is the best candidate to provide with the required cooperation An amendment of IEEE supporting vertical handovers with DVB will have high impact on offered services, hence on the market value of hybrid networks!

25 DAIDALOS /18 DVB-H Development in Nord America MDA : Mobile DTV Alliance promote the adoption of Mobile TV technology via DVB-H Disney, HiWire, Intel, Microsoft, Modeo, Motorola, Nokia and Texas Instruments currently two broadcasters in North America (Modeo and HiWire) building out mobile TV broadcast networks based on DVB-H. MediaFLO the only serious competitor

26 DAIDALOS /18 Survey Results in USA (DVB-H) 99% of users were satisfied or very satisfied (64%) with the picture clarity. 87% of users were satisfied or very satisfied (37%) with service availability 98% of users like or very much like (75%) having live TV and radio available on their cell phone Average viewing sessions lasted minutes with most viewing on weekdays; Average number of minutes viewed per day averaged around 15 minutes. 52% of users said they watched more TV overall as a result of having the service available to them.

29 DAIDALOS /18 Advantages of Hybrid Networks DVB-H network operators profit from: Virtual bidirectional channel AAA support Enabling more services as a result of interactivity Customized advertisements, Mobile TV, live polls, purchase banners, interactive games, chat services, webcasting, file transfers… 3GPP/3GPP2, IEEE network operators profit from: Market penetration with little investment DVB-H supported by the EU commission as the mobile TV standard 20 billion expected revenue in 2011 (2 million subscribers in 2006, 6 million in 2007) Use of existing broadcasting brands New services as with DVB-H Multicasting with much better quality, to a larger set of customers with one transmitter

31 DAIDALOS /18 Step 2: DVB with virtual bidirectional link No changes needed in the standard as long as L3 is used for interaction with peer MIHF entities Handover with DVB in virtual bidirectional case includes handover of the downlink channel handover of the uplink channel (other technologies) Task group should define required interfaces in order to: determine the need for virtual bidirectional channel manage the choice of the uplink channel for DVB build virtual bidirectional channel for interactive services manage handovers of the uplink channel (stable virtual bidirectional link) manage changes from virtual bidirectional to bidirectional or vice versa

32 DAIDALOS /18 Step 2: Integration of bidirectional DVB DVB Interface MIH Function Higher Layer Trasport MIH User DVB Network Transport of MIH protocol for DVB is over L3 MIHF protocol at link layer would require changes in the standard MIHF must be aware of unidirectional interfaces If no other technology with L3 connectivity exists, it is not possible to send MIH information, although MIH relevant information can still be received over DVB Network
