• Requirement for greater spectrum efficiency – Spectrum Congested – No growth without digitisation – Increased spectrum efficiency (in

8 MHz)

• Yielding a digital dividend – Huge demand for spectrum – Huge potential for new services – Other users and services

• Consumer message – Better Sound and Pictures – More channels (services) – Enhanced viewer experience

Drive for Migration to Digital Broadcasting

Defining the desired outcomes

• Spell out the desired outcomes – Interrogates broad policy

statements

– Gives focus

– Gives clarity on goals to be achieved

– Assists in setting priorities

– Informs implementation plans

• Universal access

The Steps in Digital Migration

Dual Illumination

• Network roll-out (Digital) • Integrated Digital Receiver /

Set Top Box – Specification – Manufacturing – Distribution – Retail – Installation

• Dual illumination • Uptake • Analogue Television Switch-

off • Yield Digital Dividend • After sales support

Digital Switch-on

The Home Environment

Analogue Television

Digital Terrestrial Television Set-Top Box or Integrated Digital TV required

The Home Environment

Analogue Television

• At edge of coverage or with poor antenna “some” picture still viewable

• Many TV households today – use poor antennas

– rely on marginal analogue TV reception

Digital Terrestrial Television

• Set-Top Box or Integrated Digital TV required

• Unless sufficient signal is available no service is decoded or displayed – Poor / old antenna may not work – No “marginal” reception

• DTT will be on frequencies not necessarily covered by current antennas

• New antenna and installation may cost more than the STB

• Antenna and installation as important as STB – both to be considered in incentive schemes / subsidy

Migration is all about the Home Environment

How long has migration taken in other markets

Content is King

• The viewer has been promised more channels

• Great content = the biggest incentive to migrate

• See report and video on SOWETO trial (www.sadiba.org)

• If what is available on DTT is neither compelling nor attractive migration will stall – Slow / no uptake of STB – Self-funding gap significant – Retail might be stuck with STB not

moving – Could result in manufacturing stalling – Risk of negative consumer sentiment

towards migration and digitisation

• STB (even if given away for free) unlikely to move from retail, get installed and used if no compelling content available

11

SOWETO DVB-T2 trial update March 2011, Video available at www.sadiba.org

Regulatory and Content

• Regulatory – Content regulation

• Channel Authorisation required

• Must be simple and quick process

– Networks and Multiplexes • Paradigm shift required

• Sharing capacity

• Content – Filling the capacity with quality

content

– SD / HD

– Compelling

12

No compelling content = no or slow uptake

Number of channels on DVB-T2 trial in SOWETO = 21

Typical National Rollout • Trial

– Engineering skills – Impact on the home – Trial participants –closed group of representative citizens

• Plan and prioritise the rollout • Install transmission infrastructure and prepare for switch-on • Have a coordinated roll-out and switch-on

– National switch-on requires national DTT network on-air – Regional switch-on requires stepped approach and detailed

communication

• Dual illumination – Retail, consumer education, receiver and platform marketing

• Switch-off – National – By region – By site

14

Conclusion • Migration is about the consumer and the home environment • The receive antenna is as important as the STB (Antenna

subsidy?) • All implementation factors must be considered and in place

to ensure success • Implementation planning is critical • Migration has typically taken more that 6 years • In markets where the majority of the population relies on

terrestrial reception migration has taken more than 10 years • Retail and installer capacity is likely to be a key bottleneck /

opportunity to create jobs • Content is key to consumer uptake of DTT and successful

migration. It is essential that compelling content drives uptake

• No compelling content = No or slow migration

Migration is about the home
