Tanzania’s
long awaited journey to digital broadcasting began with Dar es Salaam amid
earlier concerns that the pricing of decoders would prevent millions of viewers
from migrating to the new and clearer transmission platform.
While some had expressed fears that
decoders were beyond the reach of many homes, a number of providers reported
last week that sales made ahead of the switch off date overwhelmed the stock
they had. "We got the right sales volumes as thousands turned up to buy
the gadgets needed to switch to digital," said Mussa Mohammed, a dealer in
Kariakoo.
The switch from analogue to digital
broadcasting requires both broadcasters and consumers to buy new equipment that
converts analogue signals to digital. In an interview with state Broadcaster
TBC, Tanzania Communications Regulatory Authority (TCRA) Manager for
Communications, Mr Innocent Mungy, said the new era would open opportunities,
noting that the migration to digital broadcasting is expected to unlock the
frequencies logjam and break the long queue for licences by those seeking to
invest in the country's vibrant broadcasting sector.
"Anyone can now invest in this
industry. Even journalists can now make their own programmes and sell to any
interested station and make money out of their efforts," he said. He said
a single analogue frequency could carry as much as eight channels on the digital
platform, offering the TCRA the opportunity to end the long queue of investors
who always wait to enter the broadcasting market.
He said an increase in the number of
broadcasters is in turn expected to spur growth down the chain, especially in
the content generation market to keep the stations running. He said this would
also help broadcasters to air more local content, something that opens up a
huge business potential for homegrown production houses. Yesterday's rollout of
digital broadcasting is the culmination of a three-year process that began in
2004.
In a statement by the Minister for
Communications, Science and technology, Prof Makame Mbarawa, yesterday, he said
the switch to digital in Dodoma and Tanga would be January 31, Mwanza February
28, Moshi and Arusha March 31 and Mbeya April 30. He said the switch changes do
not involve satellite, cable and radio broadcasting services.
Digital Broadcasting milestones in
Tanzania dates back in 2004 when the Regional Radio communication Conference
was held in Geneva to establish the technical basis to facilitate Frequency
spectrum planning and the form in which the requirements of administrations was
to be submitted.
In 2005 the Converged Licensing
Framework with accommodated Digital Broadcasting First Public Consultation
Document on Digital Broadcasting Landscape was adopted. In 2006 Regional Radio
communication Conference which was held in Geneva converted all the analogue
assignment done to Digital assignment followed by signing of agreements and
approved digital plan.
In the same year the National
Planning and Assignment of Digital frequencies, second Public Consultation
Document on Introduction of Multiplex Operators (Signal Distributors) as well
as formation of the National Technical Committee-Digital Broadcasting to
oversee the migration was established.
In 2007 a series of sensitization to
Government and stakeholders were kicked off followed by the Cabinet Policy
Document on digital migration and formation of National Steering Committee on
Digital migration the following year. In 2010 licences for three Multiplex
Operators namely StarMedia (T) Ltd, Agape Associates Limited and Basic
Transmissions Limited was granted followed by the enactment of new governing
digital migration and the Electronic and Postal Communication Act the same
year.
Migration to digital TV is a global
project that began at the 2006 telecommunications conference in Geneva that set
June 2015 as the deadline by which all broadcasters are expected to have
migrated to the digital platform. In an interview yesterday, a Telecom
Engineer, Godwin, said digital formats like PCM (Pulse Code Modulation) can
hold the exact digital format of sounds.
He also said digital signals can be
checked for errors. "Generally, all digital transmission methods use 'head
labels' to provide better checking facilities. Head label may contain how many
packets may need to complete the transmission, what is the sequence number of
each packet of data, acknowledgment labels etc," he said.
He also said a variety of services
can afford over one line. "For example, IpTV connection can be used to
watch cable TV channels while browsing the Internet through a PC using same
line. This line can also be used to make a phone call at the same time,"
he said. Other areas touched were that digital data can be compressed and
therefore possible to pass over higher bandwidths.
Any digital data; data, image, video,
voice can be compressed. He said it was more secure, and easier way to
integrate different digital formats. He said digital transmission provides
higher maximum transmission rates via medium such as optical fibres, noting
that digital transmissions use less bandwidth. He also said local assemblers
and software developers are also expected to benefit from installation business
and development of software that will help record programmes for later viewing.
He said Call centres will also
benefit as more pay-TV operators get room to enter the market and will be
looking for customer care services. A number of countries have started
migrating despite numerous challenges, US is among them but they had to push
their deadline ahead so as to come up with the incentives for both end users
and broadcasters to ensure smooth migration. South Africa is among the
countries that have migrated from analogue to digital.
