What is Digital Television?

Click / Touch the question to see the answer

Digital technology allows a signal to be compressed into a smaller bandwidth. This allows more data to be sent in the same bandwidth thereby allowing for more channels to be broadcast. For example, 8 new Digital TV channels can be provided in the same bandwidth as one analogue channel.
An analogue signal can have any number of values. A digital signal can have only the values zero or one. A digital signal can be more easily corrected of errors caused by unwanted electronic noise than can an analogue signal. This is why an analogue TV picture like SABC becomes gradually more snowy as the signal weakens whereas a digital TV picture like DSTV remains perfect while the signal weakens until a level is reached where the error correction electronics can no longer function, at which point the picture freezes.
These are simply different ways of broadcasting a signal. Satellite television broadcasts from a satellite in space from which you receive 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.
This is the process of moving from an analogue to a digital TV broadcast.
In keeping with other countries and advancing technological developments worldwide, the government has decided to migrate from analogue TV to digital. The benefits of digital TV broadcasting include:
  1. Excellent picture quality
  2. Clearer sound
  3. More channels
  4. A digital TV guide which can be easily updated for more accurate schedules.
  5. Interactive services like games or the Weather channel.
  6. Picture quality which does not deteriorate with a weaker TV aerial signal. Your TV picture will either be perfect or you will have no picture at all. No more snowy pictures.
  7. Allows transmission of high definition (HD 1080) TV pictures
For most TVs you will need an STB (set-top box) - which is similar to a decoder - and a TV aerial which could be indoors or outdoors depending on the signal strength in your area. Without an STB your TV won’t be able to display the digital television picture. However the new generation Smart TVs with built-in digital tuners for the DBV-T2 format don't need an STB to view DTT channels.
No - Your existing DStv or OpenView or Starsat decoder receives a satellite signal and will not be affected by Digital Broadcasting Migration.
In theory you should not need a new tv aerial, but in practice most existing TV aerials are now old and rusted so will probably need replacing. Depending on how strong the DTT signal is in your area it is possible that an indoor aerial may work.
HD television is not required to watch digital broadcasts, but if the programme content was recorded in High Definition the user of HD Television will see improved clarity and detail which was never possible on analogue broadcasts.

Field trials for DTT started in November 2008. The SABC and e.tv tested free-to-air digital transmissions while M-Net tested PayTV digital transmissions on a selected group of viewers. During 2019 Bloemfontein analogue TV transmitters were switched off and replaced by new digital DTT transmitters in the DVB-T2 format. Sentec announced that digital migration in other areas will follow. In Pretoria a bouquet of Digital channels is available even while analogue tv is still broadcast.
The government announced in 2008 that we would be using the DVB-T format for our digital terrestrial television. Then in 2010, the government called for another review of the ISDB-T format. This, despite two previous reviews in a consultation process that began in 2000 and investment of R250 million by independent broadcasters in the DVB-T system. In January 2011 the minister of communications announced the decision to use the DVB-T2 format and Sentec subsequently spent billions on digital TV technology and over 800000 set-top boxes intended for free distribution to households earning less than R3200 per month. As usual, the allocation of contracts to the politically connected caused delays. Finally in 2019 DTT was operational in Bloemfontein and the analogue TV transmitters were switched off. Other cities were expected to follow shortly but this has not happened. Pretoria for example has 14 Digital TV channels available for viewing even while analogue TV broadcast continues.
In October 2019, SABC chief executive Madoda Mxakwe announced that the SABC planned to make use of direct-to-home (DTH) satellite television technology to pursue its digital strategy and would rely less on the DTT system, so now the future of DDT in South Africa seems very limited.
Set-top boxes suitable for the DVB-T2 format of DTT are already in South Africa and were distributed from Bloemfontein post offices for free to households earning less than R3200 pm. Sentech has approximately 800000 units in warehouses but for unknown reasons, these are not freely available for purchase. It is possible to buy a combination DTT & Satellite set-top box from takealot.com and some specialist suppliers such as TV + Video Doctor
Nothing. The changeover to DTT only affects broadcasts received on a TV aerial. DSTV and OpenView and Starsat are received from a satellite dish and are already in digital format.
No, will you will need to have a TV aerial installed and a DDT Set Top Box connected to your TV in addition to your DSTV if you also want to watch DTT programs.
Only if you want each TV set to show different channels at the same time, otherwise one STB will be able to display the same program on multiple TV's provided that your TV aerial wiring is correct.
