  1. Is Digital Audio Broadcasting viable for South Africa? Presented by Thabani Mkhize and Andy Leve Radio goes Online course 2012

  2. Discussion points • Introduction • explanation of Digital Audio Broadcasting (DAB) • Positives • Negatives • South African context

  3. Introduction • Broadcast and telecommunications networks like radio, are being digitised worldwide • Quality service, greater choice, interactivity and multimedia are important now. • DAB is one of the ways radio is achieving this

  4. How does DAB work? • audio is encoded to a digital signal. • This goes to a multiplexer and is transmitted to a network distributor on AM/FM and then to the receiver. • Multimedia • Carries “radio text”

  5. Positives • real time information, song titles, genre, album details, programme guides etc (similar to RDS found in some cars) • Better functionality- no frequency finding • More stations on spectrum • Pause and rewind feature • Less pirate stations • Clear sound

  6. Negatives • If the signal is weak you get no transmission at all. • Expensive to maintain ( equipment, transmission sites ) • Questionable audio quality because we are “squashing “more stations “on spectrums • High humidity could damage the internal parts thereof not working at all

  7. Digital Radio in South Africa • in the “thought stage” so the viability is still in question... • Radio is the most popular medium- if we go digital what will it mean for the common man ? • expensive for consumers -will people afford the headsets ? • Rise in transmission costs of stations?

  8. South African situation • No clear direction • More focus on TV • Trial runs from 1997 -2010 on 5FM, Highveld, Metro FM, Radio Pulpit,YFM,702, and Classic FM only.

  9. South African situation SADIBA says: Radio in SA requires • Expansion into new markets • No FM frequencies in key metro areas • Universal access to all language services in all centres • New broadcasters

  10. Niche services • Lower / new cost structures • FOR THEM DAB CAN DO THIS

  11. Government released a digital migration document and noted the developmental issues we face : • Digital divide • social cohesion • Employment • Common identity SO HOW WILL DIGITAL AID THIS?

  12. For government: • DAB = Curbing the divide: more platforms to provide information • Facilitating e-government services • ICT services for all • Digital content hubs

  13. Jane Duncan ( 2010) wrote with TV : • digital migration can lead to more channels with fewer owners. • They could only broadcast commercially-driven programming that fails to address even the most basic informational and educative needs of society. • Is that what could happen with radio ?

  14. What must be done to give it a shot? • commercial broadcasters, broadcast network operators and industry collaborate • quality assessment trials countrywide • Transmitter network rollout – how and cost • Clear regulations and licensing • Inform the public
