Abstract:

Mobile TV is a promising new service that

looks poised to become hugely importantfor the mobile industry. Almost everyone

on the planet is familiar with the concept of

TV and it is a part of everyday life. MobileTV is instantly understandable to

consumers and therefore provides a way of attracting even the most technologically

conservative users to access mobile dataservices. Market research indicates that

many consumers show an interest in

watching their favorite programs on their mobile devices. Furthermore, analysts

predict that consumers are prepared to pay

several Euros per month for the service,which will bring a significant boost in

overall data ARPU. Opening the door to

mobile data in this way could help tosignificantly boost user adoption of other applications and increase traffic on

existing, high-capacity WCDMA

infrastructure.

TELEVISION ON YOUR MOBILE

Strategy Analytics predicts that 116 million people will be watching TV on their mobile

device by 2010, bringing annual revenue of

more than USD 5 Billion. There are severalmethods for bringing TV services to mobile

devices, notably on-demand or real-time

delivery over cellular networks likeWCDMA and dedicated mobile broadcast

networks such as DVB-H. All systems have

their advantages. Right now enabling

consumers to access video content over cellular networks provides the major

opportunity for mobile operators.

Video services evolutionTV has proved to be a

continuously evolving technology and inrecent years the pace of change has

accelerated. Recording devices have

already made the idea of time shiftingcontent a familiar one, with viewers

watching programs whenever they choose.



Mobile TV will deliver the added ability to

location-shift content so users can also

view it wherever they happen to be. Moreefficient digital TV is beginning to replace

analog TV channels, which will free up

radio spectrum that could be used to provide High Definition TV (HDTV) to

residential users and for broadcasting

mobile TV using, for example, DVB-Htechnology. Interactivity is a growing trend,

with highly popular reality TV programs

already attracting considerable SMS

revenue from viewers voting for their favored contestants. In the future,

interactivity may evolve with quick access

to information on the Internet. For example,

during a broadcast football match, a wholerange of results and statistics could be

accessed just by pressing one button. Time-shifted TV is commonplace with Personal

Video Recorders (PVR) using recordable

DVDs or their internal hard disk to store

programs for later viewing. With mobileTV, recording to the device’s memory will

also be possible. Telecom operators that

already provide residential broadbandaccess are increasingly offering live and on

demand TV services over the Internet,

known as IPTV (Internet Protocol TV).Many operators are striving to become

triple-play and even quad-play providers

offering combined fixed, mobile, Internetand TV services to compete against

conventional cable and satellite TV

providers. IPTV content may be transferred

to mobile devices for watching on themove. Mobile connectivity could also be

used to set recordings or remote settings to

home devices or to pull content from ahome server to a mobile device when

traveling. Technological evolution is

helping to drive today’s mobile videoservices closer to true, always-on mobile

TV. Several mobile operators have already

piloted and launched mobile video services,

which are opening up more business

opportunities with the addition of high-

quality video streaming and real-time

person-to-person multimcommunication. It’s potentially a lucrative

market, with consumers happy to spend up

to Euro 12 a month for mobile TV(Unstrung Insider, Sept 2005) and one in

six mobile device owners “interested” or

“very interested” in seeing their favorite programs on their mobile devices (Strategy

Analytics Wireless User Survey, August

2005).

According to Roth Capital PartnersResearch, Mobile TV revenues fall into

three categories, which are Broadcast TV,

Streaming TV and advertising. The first

two of these categories include subscriptionand Video on Demand revenues. Over 100

operators have already launched mobile

video services, and the market is set for rapid expansion. For example ARC Group

estimates that the number of mobile video

users may grow ten-fold from 24 million in2004 to 247 million in 2008 (Mobile video

– worldwide market analysis and strategic

outlook 2003–2008).

The future looks rosy, but there

are challenges to be addressed. The

capacity restrictions of existing cellular networks may be an early brake on the take

up of mobile TV services. The limitations

of devices, such as small screens and battery drain, may deter some users. Apart

from time sensitive programming such as

news and sports services, simply providingexisting TV content may not be enough for

users to adopt mobile TV. Compelling

content for the mobile must be developed

and provided with attractive pricing. All of



these issues are largely solvable. Of course,

capacity will continue to be the ultimate

limiting factor, but this should increasingly become more of a theoretical limit than a

practical restriction on the success of

services.

Figure 2. Mobile TV service and

technology evolution trends

An introduction to mobile TVWith dedicated mobile

broadcast solutions on the horizon,3Gallows mobile operators to achieve afoothold in the mobile TV market today.

The opportunity lies in streaming live TV

or downloading video over 3G networks.Mobile TV services are similar to media-

file download services offered by all 3G

providers, apart from the fact that the live

TV feed is encoded and made available in

real time. Today’s mobile video services

generally fall into three categories.Content-to-person video messaging refers

to a case where the video clip originates

from a commercial service on a pull or subscription push basis. Digital Rights

Management (DRM) will define the usage

rules for commercial quality content, whilethe available memory capacity of the

device will determine the amount of

content that can be stored. Video download

refers to the delivery of video clips to amobile device, usually through discovery

such as mobile browsing and then followed

by a TCP/IP session where the clip is sent

to the device to be viewed or stored.Similarly, DRM and available device

memory apply regarding local storage onthe device. Video streaming indicates

immediate consumption of on-demand or

live video content on a mobile device. The

content is not stored on the device, so thismethod allows the consumption of large

video files regardless of the on-board

memory. The elimination of data storagealso simplifies the situation regarding

DRM. Numerous consumer studies and

Mobile TV pilots run by a variety of industry players show that it is conceivable

that mobile TV will create a new form of

prime time TV as viewers gain moretimeslots and more places in which to

watch. The main reasons for subscribing to

mobile TV services include:

• Spare time: People can use their spare

time to watch TV when travelling on trains,

planes, buses, or simply when waiting• Must see: Consumers will use their

mobiles to keep up to date wherever they

are to ensure they do not miss their favoriteshows

• Catch up: Devices are used to watch key

moments unfold, such as important

breaking news or during sports events



• Quick escape: Users can get some quick

entertainment when they need a break In

the background: Many people like to havesome form of background music or other

entertainment playing when they are

concentrating on tasks either at work or inthe home

Evolving cellular technologies to

enable mobile TVMobile TV and video services can

consume considerable network resources.Operators must find solutions to prevent their

3G networks becoming overloaded when

several users are accessing mobile TV

simultaneously. Reliability of the service and

credible access times are vital to viewer satisfaction.

Mobile TV use patterns affect radio

network performance :Mobile TV services demand application bit

rates of the order of 100 to 300 kbps. Theyrequire both excellent coverage and

capacity from the radio network. In

addition, transport capacity out to the basestations is a potential bottleneck for high bit

rate applications in cellular networks.

Operators need to consider the followingfactors when assessing the demands thatmobile TV will make on their networks:

• How many hours a day will users watch

mobile TV?• How many users does each base station

need to serve?

• What is the overall capacity requirement?• How will the network cope with peak

demand generated, for example, by popular

programs?

Figure 3. The average daily Mobile TV

usage time available for each user

decreases as the number of users increases.MBMS will support longer view times

particularly during peak capacity times.

WCDMA networks can already provide agood level of service, although the capacity

will need to increase in future. EDGE can provide services beyond the WCDMA

network coverage areas. Even better, 3G provides a strong evolution path with the

adoption of High Speed Downlink Packet

Access (HSDPA) and MultimediaBroadcast Multicast Services (MBMS) and

further into the future, Long-Term

Evolution (LTE) technology.

What can cellular technologies

achieve today and in the future?

• WCDMA enables cost-effective mobileTV today via point-to-point streaming.

• EDGE enables mobile TV beyond the

areas covered by WCDMA.• HSDPA further improves the efficiency of

Mobile TV over WCDMA.

• 3G MBMS provides peak capacity via

multicast and broadcast support.• LTE will provide enhanced broadcast

efficiency using OFDM modulation.

Avoiding network congestion is a strong

driver for a broadcast solution to replaceexisting unicast services. The point-to-point

approach of WCDMA and HSDPAeffectively enables an infinite number of

channels for a limited number o users. The

multicast and broadcast support provided in

MBMS instead offers operators the ability



to deliver a limited number of channels to

an infinite number of viewers.

WCDMA – the leading 3G

technology:

WCDMA is a well-established technology that enjoys

worldwide support from regulators,

operators, network suppliers and terminalvendors. By mid-2006, 108 commercial

WCDMA 3G networks in Asia and Europe

had brought the benefits of fast delivery of services to more than 64 million

subscribers. WCDMA can deliver high-

quality Mobile TV at bit rates up to 384

kbps.

EDGE – essential for 3G success:An evolution of GPRS

technology, EDGE brings three times the performance of GPRS, achieve in an

average data rate of 80 to 160 kbps per user

with 2–4 timeslot mobiles.3G subscribersare most commonly handed over from

WCDMA to GSM/EDGE when they move

out of the WCDMA network coverage area.The performance of EDGE is vital to

maintain good service continuity in such

situations.HSDPA – evolving to greater

performance:With Mobile TV, the

available downlink bandwidth is thelimiting factor in the delivery of video

streaming services. Already being deployed

y several operators, High Speed Downlink Packet Access (HSDPA) provides a major

capacity, performance and speed boost to

existing 3G WCDMA networks. In addition

to higher bit rates of up to 14.4 Mbpsdownlink, HSDPA crucially offers lower

cost per bit by enabling higher cell

throughput for Mobile TV services.Although a major evolution of 3G radio

access technology, HSDPA is available as a

simple upgrade to existing WCDMAnetworks and provides new performance

levels that coexist with existing WCDMA

usage. Not only does this bring more value

to operators’ existing investments inWCDMA, but it also makes HSDPA low

cost and quick to implement. Being based

on proven and well-established commercialWCDMA technology is a big advantage.

Operators can be certain that HSDPA is a

mature technology with proven performance throughout the chain – from

terminals through the radio access system

to the core network.

MBMS – delivering content to many

users:Multimedia Broadcast

Multicast Services (MBMS) is an extension

of 3GPP cellular standards for providingmultimedia broadcast and multicast

services in 3G.MBMS offers an efficientway to transmit data over the radio network

from a single source o multiple

simultaneous recipients. MBMS is part of 3GPP Release 6.Although HSDPA

provides sufficient capacity for average

viewing, MBMS with HSDPA provides

capacity advantages for providing identicalcontent to a large number of users at peak

times or in capacity hotspots. It effectivelyoffers existing cellular operators anopportunity to plug the gap between the

unicast and broadcast solutions.

MBMS is a cellular solutionthat can be built into existing2G/3G

networks and supports two modes of

operation –multicast and broadcast. As wellas streaming data, MBMS can deliver

content via download and play or by

carousel, in which content is delivered and

updated cyclically. The technology offerslow-to-medium bit rates of between40 and

256 kbps and promises operators significant

transport cost savings by deliveringmultimedia content to several recipients in

the same radio cell.

For users, MBMS will enable afamiliar, TV-like experience of channels



broadcasting content in real time and with

easy discovery. The biggest potential for

MBMS is in replacing current point-to- point multimedia content services with

point-to multipoint solutions that yield

significant capacity savings. ImplementingMBMS will entail a software upgrade to

future mobile networks. The first

commercial, standards-compliant MBMSinstallations are expected in 2008.

LTE – the longer term solution:Long-Term Evolution (LTE)

is the proposed 3GPP standard that aims tosubstantially reduce the cost of mobile

networks through increased performance

and simplified network architecture. The

other key benefit is that its single-frequencyapproach uses the energy in multiple cells

more efficiently, in a similar way todedicated mobile broadcast technologies.

Supporting packet switched domains, LTE

will provide up to three times the capacitycompared to Release 6 reference scenarios

with HSDPA or HSUPA, and bring radio

network user plane latency to below 10 ms

(RTT) with 5 MHz or higher spectrumallocation. Although the practical

application of LTE remains to be shown, itholds the key to multi-channel, always-onTV over 3G networks.

Content delivery over cellular

networks – unicast, multicast and

broadcast:Today’s mobile video services are unicast,

but the multicast and broadcast modes promised by MBMS will lead to significant

savings for operators.

Unicast:Unicast services set up a dedicated

session between the users’s mobile and a

streaming server. But this approach

requires a dedicated bearer channel for eachuser, even if several users are watching the

same program at the same time in the same

area. This is an inefficient use of capacitycompared to broadcast TV. So, while

unicast will remain the solution for the on-

demand delivery of clips, multicast or

broadcast solutions will take over as the preferred modes for delivering real-time,

always-n TV. Unicast is aimed at, for

example, a high variety of either live TVchannels or pre-recorded programs for

individuals, based on personal selection, as

can be seen from Figure 4.Mobile TV ondemand over WCDMA/HSPA bearers

provides more flexibility and a richer

choice than MBMS.

Multi cast and broadcast:

In MBMS, both multicast and broadcastmodes operate using a shared radio bearer

channel, which delivers services to all the

receivers within a given area. The broadcastmode requires a new network element,

called the Broadcast Multicast Service

Center (BMSC), to provide service

provisioning and delivery mechanisms. It

also acts as the entry point for content- provider MBMS transmissions into the

mobile network. A broadcast may involve asingle ongoing media stream or a

succession of streams or messages over

time. Multicast mechanisms mean that theservice need only be transmitted to cell

sites where there is an active user who is



subscribed to that service. This makes even

more efficient use of radio resources.

MBMS is most suitable for :• Coping with peaks in traffic, either

geographically (such as inside a football

stadium) or at certain times (during a popular TV show)

• Broadcasting important or popular content

(for example traffic information)throughout the service area without

knowing the number of receivers

.• Efficient content delivery through one

dedicated site to places where a largenumber of people are gathered

• Multicast of most popular nationwide

content to identified cells where enough

subscribers are watching the same content,for example, a scheduled news push

Charging:In the case of broadcast

services, charging data is generated in the

Core Network – in the Packet Core, BMSCor both. For broadcast services, only

MBMS bearer-based service charging is

possible. This generates charges based on

the MBMS sessions or data volumes per user, but it takes no account of whether the

session was successful in terms of goodreception or correct content. MBMS bearer charging is one option in the case of

multicast services, but multicasting also

allows for the following alternatives:• Charging based on session duration.

• Charging based on membership to a

multicast group.

• Charging based on the volume of contentdownloaded during a multicast session.

A consistent user experienceis critical to success:

Whatever the access

technology, and no matter what the contentdelivery mode, it is vital that users are able

to enjoy consistent and high quality

viewing. Like any new service, mobile TVmust be easy to access and easy to use in all

circumstances, otherwise users will quickly

abandon the concept.

With mobile TV, users must have access tothe same

functions and channels in a consistent

way .An integrated interactive service is a particular strength of mobile TV. TV

programmes that ask viewers to vote on

what they want to see next, or on theoutcome of a reality TV show, for example,

must work consistently across all

technologies . So when a user decides to

vote ‘A’, the hand set automatically sendsan SMS to the relevant channel. Similar

interactive mobile TV concepts include the

downloading office files from Internet links

provided by the TV show.

Operator building blocks for a

successful service launch:The creation, launch, marketing

and running of a successful mobile TVservice involves many differentconsiderations, each of which demands

methodical analysis. It takes more than just

launching a mobile TV service to generateworthwhile revenue. The service must be

easy to activate and use and must also

provide users with value for money and be



capable of enriching their lifestyle. A

logical five-stage process helps to ensure

that all aspects of creating and launching aMobile TV service are covered ,starting

with a clear understanding of the

opportunity and market need.

1. Innovate: Creating more value through

innovation

2. Create: Ensuring all players in the valuechain contribute efficiently to the

development of the service

3. Launch: Reaching the largest possible

relevant audience

4. Grow and capture the mass market:

Creating ease of use to achieve mass

market penetration

5. Maximize service profitability: Ensuring

service Longevity Close management of theservice’s life cycle is essential for the

efficient use of operator assets and to retain

customers.

Conclusion:Mobile TV over cellular

networks represents a major opportunity for mobile operators. This is partly thanks to its

direct revenue-generating potential and

partly because the concept is so easy tounderstand that it will encourage any mass

market consumers to make their first forayinto data services. Operators can also

benefit from additional traffic via the returnchannel embedded in the broadcast

environment (programme interaction,

purchasing, data and web-based

services).Furthermore, the service is viablewith existing WCDMA networks.

Emerging technologies such as HSDPA

will increase the available bandwidth andcapacity on existing WCDMA networks

and ensure that unicast services continue

to offer opportunities for operators in themedium term. Beyond this, multicast and

broadcast services will significantly

improve bandwidth and efficiency using theMBMS standard. However, even MBMS-

based services are likely to be more

efficient versions of today’s intermittent,

clip-based video services, rather thanalways-on TV channels. Looking further

ahead, 3GPP is already drawing up

proposals for LTE, which will boost datarates by two or three times compared to

WCDMA. The LTE networks will be able

to provide the type of always-on TVchannels that viewers are familiar with.
