  4. MDTV TechnologiesA Quick Technical Fact Sheet 4

  5. DAB • OFDM based • 1.7MHz per RF channel • Targeting to be the digital alternative to FM radio • Not necessarily targeted for mobile / handheld • Deployed over VHF-III in most cases, L1 band in some cases • All DAB services are free-to-air • DVB-T • OFDM based • 6MHz-8MHz per RF channel • Developed by the DVB Organization (Europe) as the digital replacement of analog TV (PAL) • Originally not targeted for mobile / handheld • Deployed over UHF in most cases, VHF-III in some cases • Considerable use of the free-to-air model 5

  6. DVB-H • Based on DVB-T PHY, can use same infrastructure as DVB-T network with minimal additions • Adds mobility using additional FEC in the link layer • Adds power consumption provisions suitable for mobile using time slicing (the receiver is operated in TDD mode) • Very good spectral efficiency, allows up to 15 TV channels including radio and data channels • Uses the Pay-TV (conditional access) model, with FTA model used only in India • T-DMB • Based on DAB PHY (Eureka 147), can use the same infrastructure using minimal additions • Adds additional FEC in the link layer in order to achieve BER suitable for video • Inherently has less spectral efficiency than DVB-H and worse power consumption provisioningCan offer 2-3 TV channels per frequency 6

  7. DAB-IP • Based on DAB PHY • Deployed over VHF-III and L1 band • Encapsulates the service (i.e. TV channel or data transmission) in IP packets and sends them over the DAB PHY using more robust FEC • ISDB-T • Japanese standard, uses up to 13 segments of 429KHz each. Each segment can have its own characteristics (i.e. for mobile, portable, etc.) • The mobile transmission is named 1-Seg and uses a single segment of 429 KHz • 3-seg mode is considered applicable for “portable” devices • Deployed over UHF mainly, with some cases VHF • MediaFLO • No legacy “parent” standard, developed by Qualcomm • Designed for mobile TV. Uses Turbo coding for allegedly best performance • Good channel switching time and video quality (equivalent to DVB-H) • Deployed over UHF, but newer versions of the spec. add also VHF and L 7

  8. S-DMB • A hybrid network that uses satellite coverage for large, nationwide areas and terrestrial repeaters for urban regions; terrestrial technology is based on 3G networks • Uses a 25MHz bandwidth in the S-band (2.630-2.655GHz) • Used in South Korea, service started in May 1st, 2005 • Service has around 1.5M users so far; business model in most cases is a fixed monthly fee • DVB-SH • Stands for DVB-Satellite Handheld • A hybrid network that uses satellite and terrestrial, architecture similar to S-DMB, will typically use the 2.167 GHz frequency and between 5-8MHz bandwidth • Uses COFDM technology • Standard is derived from DVB-H, but adds improved error correction using turbo coding • Became an official DVB standard in February 2007 8

  9. CMMB • Chinese homegrown standard, stands for China Multimedia Mobile Broadcasting • Uses the 2.67 GHz frequency and 25MHz bandwidth and COFDM technology • Standard is based on the S-TiMi technology, a combination of satellite and terrestrial transmission • Service is in trials during 2007, will be commercial in 2008. Will offer 25 TV channels and 30 radio channels • DMB-T (China) • Chinese homegrown standard, brewed in Tshingua university in Beijing • The Chinese equivalent for DVB-T, targeted for home and portable digital TV services, but will be applied to mobile also • Allegedly outperforms DVB-T in terms of the minimum required C/N signal; using TDM-OFDM technology, uses LDPC code for error correction • Could not be adopted by the industry as the nationwide standard, will be used in principal urban locations 9

  11. Deployment – Status and Future Steps 11

  12. DVB-T 12

  13. DTT Global Overview 13

  14. Worldwide Status 14

  15. Leading DVB-T Countries 15

  16. Select Channel Line-Up (Germany and UK) • On an average, each DVB-T service offers 30 channels, sometimes even more • In most cases, the majority of the services are FREE • The content is a combination of basic and premium • Video quality is superb Germany’s DVB-T offering (partial) 16

  17. Select Channel Line-Up (Cont.) • Channel Line-Up of FreeView: 17

  18. DVB-T for MDTV – a New Trend • Mobile operators are launching mobile phones with DVB-T • This is an important trend, that shows that MNO’s are no longer hesitant from dealing with the FTA technologies, and more importantly show that they strongly believe in broadcast TV and (have a good idea) how to make money out of it. • The leader in this trend is VF Germany, but T-Mobile and others are expected to follow the same 18

  19. DVB-H 19

  20. DVB-H: Current and Forecast Deployment, WW 20

  21. DVB-H: Zooming in on Europe Source: TIM, June 2007 21

  22. Commercial Services Today • Commercially available in 5 countries today • Italy: Offered by TIM, H3G and Vodafone.H3G reported around 700K users (more than 10% attach rate) and have an aggressive target of 1M users in the next few months. TIM reports around 150K users. Vodafone numbers are unknown • Finland: Launched last December, initially had issues with content licensing but recently these were resolved • Vietnam: Service launched last December, numbers unreported yet. Device used is Nokia’s N77 • India: Service launched last May, providing Free-to-Air services using the Nokia N77 • South Africa: Service launched last May 22

  23. Mobile Operators to Drive DVB-H • DVB-H is associated and driven by Mobile Network Operators (MNO) as a premium, paid service • The leading MNO’s to drive the deployment are: 23

  24. 20 Audience (%) 10 Many channels in „long tail“ Multicast Unicast Top „mass“ channels Special interest channels & on-demand content MNO’s outlook at DVB-H • DVB-H and 3G Unicast are complementary 24

  25. Forecast DVB-H Deployments • Europe • Triggering event is the European soccer championships in 2008 • Austria, Switzerland and Netherlands will deploy by June 2008 • France will deploy by EQ4 of 2008, licensed granted recently. Broadcasters (Canal+) and Operators (Orange) will share the multiplex • Russia will deploy by June 2008 • UK will probably follow by 2010 • Worldwide • Nokia reported a commercial launch in Malaysia • Taiwan is currently trialing but is expected to go commercial in 2008 • All of these above mentioned countries have existing DVB-T networks and services, and will add DVB-H services on top of the deployed NW 25

  26. Driving DVB-H thru DVB-T • By Mid-2008, the heart of Europe will have DVB-H, covering 290 million people Source: TeleAnalytics, 2007 26

  27. MDTV: Worldwide look • As DVB-H being expected to dominate Europe and APAC, it is expected to be the leading MDTV standard worldwide 27

  28. DAB 28

  29. Commercial Services Today • Over 500 million people around the world can now receive nearly 1,000 different DAB services and these statistics are changing rapidly as more licenses are awarded and more countries adopt DAB as the future of radio • Countries where DAB radio is successful:UK, Belgium, Norway, Switzerland, Denmark, Australia, Canada, and others • Existing DAB infrastructure makes it easier (cheaper) to deploy T-DMB, or DAB-IP 29

  30. Most Immediate New Deployments • Australia will begin DAB services in January 1st, 2009 • China’s SARFT has announced that DAB is the chosen industrial standard • France adopted DAB for digital radio. Licenses will be released by the government in early 2008 30
