4. MDTV Technologies A Quick Technical Fact Sheet4

5. DAB DVB-T 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
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 provisioning Can offer 2-3 TV channels per frequency 6

7. Deployed over VHF-III and L1 band
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 ( GHz)
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 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 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

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

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
