4MDTV TechnologiesA Quick Technical Fact Sheet
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
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
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
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
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

15Leading DVB-T Countries
16Select 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
Germanys DVB-T offering (partial)
17Select Channel Line-Up (Cont.)
- Channel Line-Up of FreeView
18DVB-T for MDTV a New Trend
- Mobile operators are launching mobile phones with
DVB-T - This is an important trend, that shows that MNOs
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
19 20DVB-H Current and Forecast Deployment, WW
21DVB-H Zooming in on Europe
Source TIM, June 2007
22Commercial 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 Nokias N77 - India Service launched last May, providing
Free-to-Air services using the Nokia N77 - South Africa Service launched last May
23Mobile Operators to Drive DVB-H
- DVB-H is associated and driven by Mobile Network
Operators (MNO) as a premium, paid service - The leading MNOs to drive the deployment are
24MNOs outlook at DVB-H
- DVB-H and 3G Unicast are complementary
25Forecast 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
26Driving DVB-H thru DVB-T
- By Mid-2008, the heart of Europe will have DVB-H,
covering 290 million people
Source TeleAnalytics, 2007
27MDTV Worldwide look
- As DVB-H being expected to dominate Europe and
APAC, it is expected to be the leading MDTV
standard worldwide
28 29Commercial 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 successfulUK,
Belgium, Norway, Switzerland, Denmark, Australia,
Canada, and others - Existing DAB infrastructure makes it easier
(cheaper) to deploy T-DMB, or DAB-IP
30Most Immediate New Deployments
- Australia will begin DAB services in January 1st,
2009 - Chinas 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

Olympics - Terrestrial coverage in the 6 major Olympic
cities - Service will offer around 30 channels, about 5
free-to-air and the rest Pay-TV - Business (and technical) model among the various
entities is complex - With the expected peak of 30 cities by the
Olympics. Official service launch is 1/1/2009,
but the Olympics are used as the triggering event
and the wide-media approach.

DVBT DVBH
Constellation QPSK / 16QAM / 64QAM QPSK / 16QAM / 64QAM
- Higher constellation/modulation needs strong
signal to process e.g. Induce lower sensitivity. - Higher constellation/modulation has greater data
density e.g. Can store more data information.
