MDTV 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

Leading DVB-T Countries
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

DVB-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

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 Nokias N77
• India Service launched last May, providing
  Free-to-Air services using the Nokia N77
• South Africa Service launched last May

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 MNOs to drive the deployment are

24
MNOs outlook at DVB-H

• DVB-H and 3G Unicast are complementary

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

26
Driving DVB-H thru DVB-T

• By Mid-2008, the heart of Europe will have DVB-H,
  covering 290 million people

27
MDTV Worldwide look

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

28

• DAB

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 successfulUK,
  Belgium, Norway, Switzerland, Denmark, Australia,
  Canada, and others
• Existing DAB infrastructure makes it easier
  (cheaper) to deploy T-DMB, or DAB-IP

30
Most 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

• Other Standards

44
DVB-SH

• Alcatel has practically invented this standard
  and is also driving it
• Terrestrial trial is taking place in France,
  satellite will be launched only in 2009
• Alcatel has signed an agreement with ICO, an US
  infrastructure company specializing in satellite
  and terrestrial equipment, to deliver DVB-SH
  systems to the US market
• Trial is expected to start in Spring 2008
• European MNOs are not ruling out the possibility
  of adopting DVB-SH

47
OFDM Modulation scheme
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.

MDTV Source coding format

• DVBT Standard definition (SD) bitrate can be from
  3Mbit to 8Mbit !!
• Most CPU (for PDA) is capable of H.264 decoding
  but NOT MPEG2
• MPEG2 stream require HW support or stand alone
  CPU that does the job

52
DVB Characteristic

• DVBT
• Weak in Mobility
• Require HW MPEG2 decoder
• High power consumption
• Free to Air
• DVBH
• Require CAS
• Design for Mobile device (Strong in Mobility)
• Low power consumption
• Most CPU is capable of decoding H.264

53
DVBT capable interface

• USB
• USB 2.0 HS fast enough for all stream data
  throughput
• SDIO
• Constrain
• Platform SDIO spec
• 1 bit or 4 bit??
• Max frequency? 10Mhz? 20Mhz? 25Mhz?
• SDIO host stack performance
• Maximum throughput?
• HIF
• Fast enough to stream SD HD.
• Not popular as it require many pins.
• SPI
• Technically capable with throughput of 10 to
  15Mbit
• Very dependent on Host clk speed, with or without
  DMA, ect.

54
MDTV Frequency band

• VHF 174Mhz 230Mhz
• TDMB, DAB, ISDBT 3seg
• UHF 470Mhz 862Mhz
• DVBH, DVBT, ISDBT 1seg, DMB-T, MediaFlo
