Digital Terrestrial Television (DTT)

• Applies to broadcasts that are land based

(terrestrial) i.e. ‘Free To Air’

• Impacts on existing broadcasters required to

switchover

• Impacts on new entrants granted a concession for

digital television broadcasting

3

Why Go Digital?

• Conformance to global change to digital terrestrial

television broadcasting

• Spectrum efficiency means more programmes
• Digital Dividend
• Improved quality of services delivered to the

public

4

DTT Framework Objectives

• Recommend a migration timeframe and key

milestones for analogue to digital switchover (DSO)

• Recommend a standard for DTT broadcasting
• Recommend an approach for DSO
• Highlight the role of and impact on the various

key stakeholders

5

Switchover Timeframe

• Factors contributing to the development of a

switchover timeframe:

 Global analog to digital switchover  Switch-off dates by other countries  Availability of digital TV sets and Set Top Boxes (STBs)  Readiness of existing TV broadcasters  Entities willing to deploy DTT networks i.e. signal distributors

6

Switchover Timeframe

Distinct Phases of DSO:

• Digital ‘Switch On’ - the introduction of digital

broadcasting services

• Simulcast Period - analogue and digital will be

broadcast simultaneously

• Analogue ‘Switch Off’ - termination of analogue

transmission

DTT Broadcasting Standard

• The main technology standards used globally:

 Digital Video Broadcasting (DVB-T) in Europe  Advanced Television Systems Committee (ATSC) in North America  Integrated Services Digital Broadcasting (ISDB-T) in Japan

• Region 1 countries adopted the DVB-T standard (RRC-

06)

• No recommendation by the ITU or a standardization in

the Caribbean by CITEL for a Region 2 DTT standard.

Approach To Implementation

• Policy Driven Approach – transition guided by established

processes and plans agreed upon by all stakeholders

 Moratorium placed on analog terrestrial TV roll-out  Establishment of an early and fixed ‘Switch Off’ date  Authorization of signal distributors owning and operating the transmission facilities with broadcasters seeking to provide services  Signal Distributors to be selected through a competitive evaluation process

11

Approach To Implementation

• Signal Distributor

 A common carrier which makes its infrastructure available for hire  Ensures optimal utilization of national resources and spurs rapid growth of new value added services  The traditional broadcaster is no longer involved in site acquisition, transmitting, infrastructure development and

• peration

12

Approach To Implementation

• A signal distributor introduces benefits such as:

 Lower transmission costs per broadcaster  Better efficiency in spectrum management  Lower set up costs for new broadcasters  Uniform coverage of the broadcast signal

• Single Frequency Network (SFN) vs Multi-

Frequency Network (MFN) configuration

13

Approach To Implementation

• Single Frequency Network (SFN) configuration

14

DTT Key Issues

• Framework identifies the key issues and impact

surrounding the introduction of digital terrestrial broadcasting

Policy and Regulatory Considerations Impact on Broadcasters Impact on Consumers

15

Developments To Date

• Stakeholder Consultation Process completed
• Framework for DTT broadcasting services drafted
• DTT Working Group with key stakeholders

established

16

The Way Forward

• Recommendations from DTT Working Group

Finalize DTT Framework Develop Migration Plan and Implementation Strategy

• Authorize Signal Distributors
• Develop Consumer Awareness and Education

Campaign
