State of Broadcasting and
Digital Migration in the Region

Overview of digital broadcasting migration
The digital broadcasting migration is a costly
process for both the governments and citizens.
There are costs for digital production equipment,
transmission equipment and decoders or digitally
enabled television sets. It is anticipated that
the benefits derived from the digital migration
process far outweigh the costs involved. The
transition from analogue to digital transmission
impacts television viewers, media companies
and existing television channels in varying
degrees.

Generic benefits of Digital Migration
Digital broadcasting enables utilisation of the
scarce frequency spectrum far more efficiently
than analogue technologies. Consequently the
first benefit is the freeing up of valuable radio
frequency spectrum that is used for analogue
TV transmission. The freed space is referred to
as digital dividend1 and has been earmarked
for mobile broadband.
The migration to digital broadcasting creates
opportunities for the development, use and wide
dissemination of local content. This advances the
expression and the efficient communication of
the knowledge and experience of all communities
and nations. The creation and use of local content
contributes to the integration of people from
all walks of life. Digital migration therefore
creates avenues for media freedom and content

creation which subsequently ensures access
by media practitioners to diverse information
and views. This is also beneficial to ordinary
citizens who are also guaranteed of further
access to information. Access to information is
also important for exercise of rights for purposes
of promoting transparency and accountability
and more broadly good governance.

Technical benefits of digital broadcasting
•

the digital platform offers superior
video and audio quality

•

the efficient spectrum use allows
different content providers to be
carried in a single frequency channel.
The same frequency channel that
carries one analogue TV service can
carry up to 20 standard definition
TV services or 6 high definition
services plus 20 radio channels.

•

Digital broadcasting lowers
transmission costs as the
transmitters use a fifth of analogue
power for the same coverage.

•

Digital transmission infrastructure
allows optimum utilisation of resources
since content service providers
share the same infrastructure

•

The digital environment stimulates
an increased participation in the
broadcasting sector resulting
from high demand for content and
low investment start-up costs.
