  • One of the benefits of Digital Broadcasting:

Spectrum Efficiency

    • Spectrum a finite national resource
    • Digital makes far more efficient use of the available spectrum
    • Allows for expansion and new services

challenges
Challenges
  • Digital Dividend
  • The position of communication service providers world wide is that regulators should migrate all broadcasting services from frequencies 790 – 862 MHz so that the band can be used exclusive for telecommunications services. As such
  • There is need for re-planning of the whole broadcasting band so as to give way for the new services
challenges cont 2
Challenges Cont .. (2)
  • A number of existing infrastructure is obsolete
  • This will result into high investment costs in the implementation of digital broadcasting.
  • Local content is extremely low
  • This might result into the gap being filled by unhealthy content from external sources.
challenges cont 4
Challenges Cont.. (4)
  • We need to resolve the unprofessional planning of antennae masts and towers at broadcast transmission sites:
  • The number and the way masts and towers have been constructed at Kisarawe for instance might cause screening effect among TV stations;
  • Facility sharing under MUX should be the focus in resolving this problem.
conclusion
Conclusion
  • Get prepared for the big change:
  • More contents;
  • Surround sound audios and Wider screen experiences;
  • Video on demand;
  • Personal video recorders (PVR): the convenience you get of latter watching of your favorable programs.
conclusion cont 2
Conclusion Cont.. (2)
  • Hybrid network and services allow you to better plan your day:
  • Internet, e-education, e-commerce, e-ticketing, e-government;
  • mobile TV;
  • Internet banking;
  • Quality TV via IP based networks;
  • The limit is the sky!
