Mobile-TV - What is it?

Typically 20-30 TV channels, 100’s of radio channels or

>100 gigabytes/day one way data delivery

Mobile TV is a way to broadcast content to small hand held battery powered terminals like mobile phones.


3 Ways for Mobile TV

• DVB-H is an complementary delivery technology in addition to 3G, MBMS and LTE

• The Mobile-TV and video experience can be realized with a mix of several complementary technologies.

• Multimedia services to masses and communities

• Save 3G capacity for groups watching the same content

• Mobile TV content to communities• User-controlled personalized channels and

interactivity• “long tail” TV and video

Background

• Mobile-TV has its origins in the digitalization of TV.

• First digital TV-standards like the European DVB-T appeared in mid 1990’s.

• There was an instant interest to use these on the move as this would be something old analogue TV could not offer.

• First studies were made on car reception as hand held was seen unpractical due to the high power consumption of the basic DVB-T.

• Rather soon it became clear that even hand held battery powered terminals are possible if suitable means to save power can be found.

• Question raised:

Should something be done in standardisation?

Physical Layer Standardisation

• Studies were showing that IP-streaming solutions carried over the existing digital-TV were probably the best way to proceed.

• It would have been possible to introduce mobile-TV systems by just using existing standards and adding some proprietary technologies for power saving.

• However several companies working in the area felt that a common approach within the DVB-organization would be a better way to proceed.

• Work in DVB:• Standard Extension study group (2000-2001)• Commercial requirements for mobile transmission in

CM-MOB (2002)• Technical specification for hand held reception in TM-H

(2002-2004)

• ETSI standard for Transmission Systems for Hand Held Terminals (DVB-H) published in November 2004.


Terminal Radio (RF) Specifications

• The DVB/ETSI does not make terminal specifications. => DVB-H specification does not include things like terminal sensitivity, linearity etc.

• In the other areas of digital TV this has led to numerous country specific specifications => market fragmentation.

• For terminals like mobile phones this is totally unacceptable, one unified specification was clearly needed.

• Around 15 companies who were expecting to take the DVB-H standard in use decided to create this specification so that it would be available early enough for the first products.

• Specification work in EICTA MBRAI Group:• Work started in late 2002, two years before DVB-H was

published. • Technical work finished by the EICTA group in mid 2004• Specification forwarded to IEC TC-100 as New Proposal for Fast

Track Standardization• IEC PT 62002-1 and -2 MOBILE AND PORTABLE DVB-T/H RADIO

ACCESS was published in November 2005• Global Certification Forum (GCF) is in the process of adopting

PT62002 for terminal conformance testing in DVB-H based mobile-TV.

Upper Layer Specifications for Mobile-TV

• Full Mobile-TV system requires system specifications for upper layers:

• Audio and video formats

• Electronic program guide (EPG)

• Service Protection and Purchase (SPP)

• Work in DVB-organization• DVB IPDC specifications

• Work in Open Mobile Alliance (OMA)• OMA BCAST specifications

• Profiling work in forums like the BMCO• Standards have so many options that

profiling work for the market is needed.

Targets and Benefits – Case Terminal Radio Interface• MBRAI (IEC PT62002) Radio access specification

for mobile, portable and hand held portable devices capable of receiving DVB-T/H services.

• Unified RF-specification will enable the industry to develop cost efficiently:

• RF-components (like ICs) for the mobile, portable and hand held DVB-T/H devices.

• Mobile, portable and hand held DVB-T/H terminals.

• DVB-T/H network elements for networks supporting mobile, portable and hand held reception.

• RF-specification for DVB-T/H receivers serves as a reference document for network and spectrum planning.

Results so far:

-All available DVB-H silicon tuner ICs have been designed using MBRAI.

-Terminal Antenna designs are targeting for MBRAI.

-DVB-H terminals are targeting for MBRAI performance.

-It has been used for information source for network planning in the DVB-H pilots and first commercial networks.

-GCF has adopted MBRAI.


Open and Competitive Ecosystem for Mobile TV• Success of Mobile TV requires a similar open and competitive ecosystem that has

lead to the huge success of GSM/WCDMA based mobile telephony

• Open standards must be implemented end-to-end : Terminal and Physical layer Radio standards , Service Protection and purchase (SPP), Electronic Service Guide (ESG), Audio and video formats and codecs, all associated profiles and parameters

Open, global

standard

Several vendors able and willing

to invest

Competition at all value chain layers

Good offerings at attractive

pricesRapid market growth

Further price reduction

EconomicsOf scale


Conclusions of Open Standardisation

• Benefits:• Creates developers community• Early investments through trust to the

market • Enables component and equipment

development• Enables Infrastructure development• Faster Time to Market• Interoperability• Economics of Scale• Competition=> Quality and good price

• Drawbacks:• Attractive business possibilities can create

several competing standards• Sometimes delays in standardisation can

create delays in the market.
