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
7
Switchover Timeframe
2008 2009 2010 2011 2012 2013 2014 2015

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.

DTT Broadcasting 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
operation
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
