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

4 Digital Video Broadcasting 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 DVB-H 1- Unlimited number of receivers 2- Up to 40 km coverage
DVB Transmitter 4- Supported by over 60 manufacturers 3- Around 40 channels with 300kbps

6 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 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

8 Hybrid Networks Using DVB-H

9 Convergence World of Telecom World of Broadcast

10 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) Supports DVB-H, 3GPP MBMS, 3GPP2 and mobile unicast streaming systems at the application layer Interaction with other technologies at the network and data link layer is missing and needed 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 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 How to Integrate IEEE 802.21 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 MIH Reference Model for DVB-H
Has two parts: MIH related information from DVB transmitter MIH related information from DVB interface Layer 3 or higher Mobility Protocol (L3MP), Handover Policy, Transport, Applications MIH-SAP Media Independent Handover Function (MIHF) MIH Event Service MIH Command Service MIH Information Service MIH-DVB-SAP Program Specific Information/Service Information (PSI/SI) MPEG2 DVB Device Driver MPE Higher layer Electronic Service Guide ESG

14 Integration of DVB MIH Function MIH Function 21-07-0360-00-0000
DVB Network MIH Function MIH User MIH Function MIH Function DVB Interface

15 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 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 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!

20 MIH In the case of a system with multiple network interfaces of arbitrary type, the MIH Users may use the Event Service, Command Service and Information Service provided by MIHF to manage, determine, and control the state of the underlying interfaces. These services provided by MIHF help the MIH Users in maintaining service continuity, service adaptation to varying quality of service, battery life conservation, network discovery, and link selection.

21 MIH Handover: the process by which a mobile node obtains facilities and preserves traffic flows upon occurrence of a link switch event. The scope of the IEEE (Media Independent Handover) standard is to develop a standard that provides link layer intelligence and other related network information to upper layers to optimize handovers between heterogeneous networks. The purpose of the IEEE standard is to enhance the user experience of mobile devices by supporting handovers between heterogeneous networks. The standard addresses the support of handovers for both mobile and stationary users.

22 MIH For the stationary user, handovers may become imminent when the surrounding environment changes, making one network more attractive than another. Another possibility is that the user may choose an application which requires a handover to a higher data rate channel, for example during download of a large data file. In all cases service continuity should be maximized during the handover. Various applications have different tolerance characteristic for delay and data loss. Application aware handover decisions may be enabled by making a provision for such characteristics. Network discovery is essential to provide new possibilities for network selection to suit the need of the applications and mobility. The IEEE standard defines the network information and specifies the means by which such information may be obtained for supported access networks and made available to the MIH Users. The network information could include information about link type, link identifier, link availability, link quality, etc.

32 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

33 DVB-H service of 3 Italia since 2006
Currently more than 1 million customers source: bmcoforum

34 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

35 Step 2: Integration of bidirectional DVB
MIH Function Higher Layer Trasport MIH User DVB Network MIH Function MIH Function DVB Interface 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
