Digital Television - Public Consultation (aiming
at finding out the needsand preferences of
Brazilian people)
  • To stimulate and to extend the debate on the
    definition of DTV standard
  • Given the complexity of the aspects involved in
    the definition of the digital terrestrial
    television broadcast standard, it is not
    recommended to take this decision only based on
    the laboratory and field tests
  • To collect information in order to promote the
    convergence in the business model
  • It is necessary to conciliate the most convenient
    DTV business models to the service providers,
    equipment manufacturers, content producers and
    the consumers, seeking for the best solution for
    the country

    telecommunication services according to the bit
    transport capacity of the system.
