#10things you need to know about DTT switchover

It’s been a long time coming, but the switch to DTT (Digital Terrestrial Television) is finally here.

It’s been a long time coming, but the switch to DTT (Digital Terrestrial Television) is finally here. And despite more than a decade of chatter around it, there are still people confused about DTT and what it means for them, says Megan Walker, media strategist at The MediaShop. This is after Government missed the International Communication Union cut-off deadline of 2015. “So, for TV planners the days of multi-TV channel stacking to achieve bigger reach will be over, and we are likely to need to employ a stacking model that incorporates a mix of multiple content platforms to achieve bigger reach. The job for TV strategists and planners is about to become infinitely more complicated.”

“Ministry reshuffles, corruption, and repeated litigations have slowed the transition process over the past 10 years but it’s finally happening. The Minister of Communication and Digital Technologies, Khumbudzo Ntshavheni, switched off the last analogue SABC TV transmitter in Limpopo province on 8 February 2022. The switch made Limpopo the fifth province — after Free State, Northern Cape, Northwest and Mpumalanga — to switch from analogue transmitters to digital terrestrial television (DTT) as part of the government’s Broadcasting Digital Migration (BDM) programme,” explains Walker.

1. The difference between DTT and satellite television

DTT employs a network of TV transmission towers on earth instead of satellites in space to transmit signals that are digital instead of analogue. DTT offers better picture and sound quality, more options (additional channels) for consumers, and frees up the radio frequency spectrum for mobile broadband service. These are simply different ways of broadcasting a signal. Satellite television broadcasts from a satellite in space from which you receive the signal, via a satellite dish that is mounted to your house. Digital Terrestrial Television uses transmitters on the ground to broadcast the signal which you then receive using a TV aerial and set top box.

2. It is the process of moving from an analogue to a digital TV broadcast

So, when people talk about “digital migration” or “digital switchover” – what this means is the process of moving from an analogue to a digital TV broadcast.

3. What this means for all South Africans with a TV

When South Africa goes fully digital, everyone currently using a TV aerial will need a decoder (also called a set top box or STB), which will decode the digital signal. Without a STB (like an Openview or M-Net decoder), your TV won’t be able to display the digital television picture.

4. The role of Government

Government has been responsible for developing the policy for Broadcasting Digital Migration (BDM). They are also responsible for ensuring that funding is available for the Scheme for Ownership Support (SOS) for poor households and for the development of a STB manufacturing strategy. The Department of Communications is driving this process on behalf of government and is working with other government departments such as the National Treasury.

5. Terrestrial broadcasters need to migrate their services onto digital.

Signal Distributors are responsible for rolling out the digital network infrastructure on behalf of broadcasters. The main signal distributor affected is Sentech. Other signal distributors such as Orbicom (for M-Net) are also involved.

6. Five million STBs will be distributed to TV households

The role that the South African Post Office plays is primarily one of disbursing the subsidised STBs to approximately five million of the poorest TV-owning households considered needy and deserving. For people wanting to purchase a box there are several outlets available including Makro and Takealot, and a DTT set top box will cost between R600-R800.

7. The benefits to the consumer

The consumer benefits arising from digital switchover are widely recognised, happen relatively quickly and are primarily driven by increases in programming choice and quality. There are also broader benefits to our society of introducing digital TV including the potential to use digital broadcasting to narrow the digital divide, reach unserved areas, and to provide e-government and other digital services. Cheaper access to the internet will mean greater access to information and education, upskilling, access to ecommerce and therefore overall growth and empowerment.

8. The impact to the industry

The DTT roll out impact to advertisers is some loss of TV audiences, and the job of media planners and strategists is one of managing these audience fluctuations. We believe the initial drop off will be the worst, after which some stability will return as people find their feet with whatever viewing solutions they land on. With so many new options being available to people who were once constrained by access to internet services, it is unlikely that the audience numbers of ‘traditional’ TV will ever return to what they were.

9. The overall TV universe is likely to decline

Achieving the same audience reach levels will not be possible – in fact we have seen this for some time now, even prior to the DTT transition. This is due both to the proliferation of content available for consumption and the fact that it can be consumed via multiple devices, many not yet able to have the audience numbers captured.

10. The sale of portions of the spectrum will mean there will be new players to the party

Even the established players have plans. SABC in partnership with TelkomOne will offer live streaming of SABC 1,2,3 and SABC Sports. SABC Sales are in the final preparations to adapt the bookings system with Telkom1 and are making sure it’s tested properly. Once this has been finalised, they will be launching it to the industry. Viacom plans to launch the free streaming service Pluto in SA in August this year, and while there is awareness of the paid streaming services in SA, there seems to be a gap for free streaming services.
