The Digital Terrestrial Television (DTT) Switchover: Why Completion of Implementation Process So Important

From about 2015, there has been talk of a national switchover of television viewing from analog to digital with deadlines missed severally in 2016 and 2017 and now virtually in 2018 with a new time table of switch over. In summary, Digital Terrestrial Transmission abbreviated DTT is a technological evolution of broadcast television and an advancement over analog television which involves the use of technology to transmit several channels over one transmitter and antenna system. Let me just draw the attention of all of us to the enormous benefits industry players, consumers and government stand to gain if this process is taken more seriously and implemented.

  1. Consumers would now have the luxury of as many quality picture channels as are licensed by the regulator to watch without having to change antenna positions to watch their favorite channels.
  2. There’s no longer the strain challenge posed by analog television channels where one struggles to view pictures amidst snowy transmission. With digital transmission, it’s either clear pictures or nothing at all
  3. The industry players (content providers), now have the equal platform in terms of reach, and quality of pictures to reach consumers.
  4. It reduces the proliferation of TV masts and the associated effects of the radiations which has been a challenge for the environmental agencies to deal with
  5. Industry players also have one major headache of Operations Cost associated with the installation and maintenance of transmission sites taken off their shoulders hence releasing enough cash to provide better content to the consumers
  6. Government now has some superintending level of control and can hence implement any tax or license regime using easy control measures to switch on or off any defaulters from both provider ends and customer ends
  7. For statistical purposes, it is easy to estimate any data related to television viewing with easy deployment and use of the software and hardware packages available
  8. Government has enough spectrum frequencies released for other transmission purposes after the switchover that will rake in more revenue into the national coffers
  9. Other service providers like data services (internet) could also take advantage and reach a larger population of viewers through technologies available in the digital stream, increasing revenue to government
  10. The technology will promote the businesses of indigenous companies who are into production of set top boxes and digital sets hence increasing job creation to a high crescendo
  11. It saves the government some power from the generation mix, hitherto over 20 transmitters per region would have consumed
  12. Competition amongst content providers will improve content greatly and provide viewers with the satisfaction desired
  13. Regulators can then monitor and enforce regulations regarding local content, alcohol time bands, parental control and any other regulation aimed at sanitizing television broadcasting
  14. For the frequency regulator, it saves time and energy retrieving subscription since at the click of a button, defaulters could be reached with ease

The most important ingredients however lie within the implementation process. If all stakeholders (consumer representatives, industry players – GIBA and GBC, government and regulators – NCA) will continue to dialog with effective timeliness, the country will benefit tremendously from the switchover and on the world stage be recognized as one nation ready to embrace technology to enhance growth. The experts in every sector of the process must be engaged to ensure a smooth switchover.

In Kenya for example, the initial push for the Digital Switch over three years ago was stiffly resisted by many industry players but having been implemented has proven to be a great success to both Spectrum managers and content providers or the mainstream media. Quality of transmission has improved while costs have reduced and also frequencies have become available for other uses to raise more revenue.

In Ghana, GBC has been able to successfully run tests with their T1 transmissions over Accra and Kumasi which currently handles over 20 channels. GoTV runs a paid T2 system nationwide and has a larger number of channels. First Digital also runs a paid T2 system which has proven to be largely successful and provide equal viewing opportunities to all within the transmission catchment areas. It’s time to switchover yet we must ensure the topical issues posed by industry players are effectively addressed
