  2. 1990 2000 1950 2010 1970 1960 1980 Time for mobile TV and digital radio MHz GHz 1000 x clock kbyte Gbyte 1000 000 x memory Technology Enablers: Microelectronics Radio technology Compression technology Display technology battery technology etc. Technology enabler: Transistor Tube radio Transistor radio

  3. Interactivity & transactions Call Web Application VideoOnDemand SMS Filecasting Up to 50 TV channels, 100s of radio channels or>100 gigabytes/day one-way data delivery capacity with almost zero marginal cost/user enabled by Digital Rights Management (DRM) DVB-H fundamentally changes mobile media delivery Electronic Service Guide TV/Video Radio/Audio

  4. Benefits of DVB-H for radio applications • Share the network infrastructure built for DVB-T/H • High network capacity, low cost per program • Future proof IP based technology • Extremely low power consumption, >30h with AA size battery • Integrated antenna -> easy to integrate in headset or in to a pocket receiver with BT (Bluetooth) headset • DVB-H supports several alternatives for service and content protection • Technology integration to portable devices on going (phones, PDAs, etc) This slide could be replaced with the next 3 slides?? May be not time to go throuth all

  5. DVB-H digital radio, benefits for broadcast network operator • Service provider can share network capacity between mobile TV, radio and other broadcast multimedia service providers • No need for separate digital radio networks • Transmission capacity can be freely allocated depending on actual needs • Transmission capacity and audio codecs for different radio services can be freely changed • Each service can allocate just the capacity it needs • Like commentary audio could use 24 kbps, but 128 kbps could be reserved for high quvality services. • DVB-H standard support also toolbox model where additional codecs can be as well used. • System scales also dor multi channel audio (5.1) • Encryption system can e common for mobile TV and radio services

  6. DVB-H digital radio, benefits for service provider • Low distribution costs (minimum investments for a single service operator) • IP based technology makes multi channel (via different medias; broadcast, internet, ) offering easier • IP technology rely on standard components and existing intranet connectivity to the broadcast station • System is future proof (All IP) • Visual elements can be linked to the radio service (still pictures, animations, video) either via H.264 or via file cast mechanisms • Interactivity can be linked to the radio service

  7. DVB-H digital radio, benefits forconsumer • The devices will be cheap (high volumes for silicon, same chips for mobile TV) • Long battery life (due to time slicing) • Automatic handover (possible with a single tuner due to time slicing) • Receiver antenna can be integrated inside the terminal (due to short wavelength and good propagation in the UHF (470-750 MHz) • Very good mobility and functionality in multipath environment (due to wide 8 MHz RF channel and 3 layer error correction) • Good indoor coverage (due to needs for mobile TV indoor coverage) • Radio can be used to receive mobile-TV sound channel

  8. Example: DVB-H radio services cost in Finland • Radio services January 2008 including service encoding, service composition, transmission, transmitting, monitoring 24/7 and as an option encryption and interface to manage program information and transmitting the program info. • National coverage 40% (Jan 2008) • Enhanced radio service 9600 €/month • Radio service (audio) 8400 €/month • Regional services (some cities) • Helsinki: Enhanced radio service 4400 €/month • Turku: Enhanced radio service 2500 €/month • Oulu: Enhanced radio service 1400 €/month Source: http://www.mobiilitv.fi/Yrityksille

  9. Time Slicing –Key element of DVB-H Transport Stream • Time Slicing alters the Transport Stream functionality • Each service is split in to time sliced bursts (A,A,A.., B,B,B…) • DVB-H receiver is switched on only when receiving time slices of the selected service • Power saving is achieved by switching receiver on only for time periods receiving the desired service • Receiver has to switch on slightly before the next burst to have time for tuning and synchronisation, Synchronization Time A B C D E A B C D on Receiver off Cycle time A B C D Synchronization time

  10. Time Slicing gives Handover Support • In normal DVB-T systems Smooth handover would require two front ends in single terminal • Time Slicing offers, as an extra benefit Chance to monitor neighbouring cells with same receiver during off-time Soft handover possible Maintaining the service F3 Adjacent Cell A B C D E A B C D E A B C D E A B F3 B C D E A B C D E A B C D E A B C F2 F2 Adjacent Cell A A A A F1 Off time to listen F2 Off time to listen F2 Off time to listen F3 F1 Serving Cell

  11. DVB-H system suitable for all radio applications • High mobility and low power consumption enables all conventional radio receiver applications • Use of the UHF spectrum 470-750 MHz for transmission gives several benefits • Small receiver antenna, can be integrated to all devices • Good signal propagation leads to economic network infra and indoor reception

  12. Economic of scale can be reached only via Multimedia networks – heavy competition IP Radio over GSM & 3G Car Radio Radio in Train Radio Receivers In Cellular Phones Higher mobility Portable Radio Receivers HiFi Home Radio IP Radio over BT & Wimax Radio over Broadband IP Lower power consumption

  13. EU Commission decision 17th March 2008 • “DVB-H is currently the most widely used standard for Mobile TV in the EU. DVB-H is currently between trials and commercial launch in 16 countries. Commercial DVB-H services are already available in Italy, with further launches expected later this year notably in Finland, Austria, France, Switzerland and Spain”. • After publication of the Commission decision in the EU List of Standards in the EU's Official Journal, Member States will be required to encourage the use of DVB-H.

  14. 17th March 2008 DVB-H added to list of EU official standards

  15. History of DVB-H Mobile TV & Radio Terminals Nokia N96 Nokia 7700 Nokia 7710 NokiaN92 Nokia N77 • Mobile TV Server Solution 2.2 • over 15 pilots Commercial mobile TV Server Solution 3.0 - First commercial services 2003 2007 2008 2005 2006

  16. Example: Mobile TV and radio combined to a single DVB-H multiplex • DVB-H parameters: 16QAM, CR=1/2, GI=1/8 MPE-FEC=¾ --> 11.08 Mbps • 11 time slices --> 1 Mbps/time slice • 750 kbps / time slice after MPE-FEC • Very short channel switching time can be reached by transmitting radio programs within the same time slice • This example gives net bitrate 64 or 96 kbps for each radio service • Statistical multiplexing for TV services (min +20% capacity) 1 second Radio 1, 2, 3, 4, 5, 6, 7, 8, 9 Radio 20, 21, 22, 23, ...32 Radio 1, 2, 3, 4, 5, 6, 7 Radio 8, 9, 10, 11, 12,...19 Radio 19, 20, 21, 22, ...31 Mobile-TV9, TV10 Radio 1, 2, 3, 4, 5, 6, 7 Radio 8, 9, 10, 11, 12,...19 Mobile-TV11, TV12 Mobile-TV13, TV14 Mobile-TV15 ESG Mobile-TV7, TV8 Mobile TV1, TV2 Mobile TV3, TV4 Mobile TV5, TV6 • 32 pcs radio services: 62 kbps or 107 kbps / service (including 5...10 % for IP and Conditional access etc) • 15 Mobile TV services: min.384 kbps /service • Electronic Service guide , ESG (375 kbps)
