Why Digital Broadcasting ? Cont .. (2)

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

Strategy Objectives: Increase understanding and

awareness on the impact of the migration to digital broadcasting by key stakeholders in the country;

Increase awareness to service providers regarding new business opportunities brought about by the introduction of digital broadcasting.

Strategy Cont.. (2)

Formation of National Technical committee to chart roadmap for the migration process,

Consultation with stakeholders in the broadcasting sector

Splitting of functions: Content provision: CSV (broadcaster) Signal distribution: MUX (Multiplexer)

Strategy Cont..(3) Phase Implementation Double illumination Awareness campaign Digital Dividend The use of freed spectrum Replanning of the band What new services are proposed to be

introduced (Mobile services on International perspective – IMT 2000)

Strategy Cont.. (4) More on Regulator: Licensing MUX; STB standardization; Put in place the necessary laws and

regulations to govern the migration process and beyond;

Harmonization: To minimize cross border interference between neighbors, harmonization on the spectrum use across the borders is a must.

Implementation Issues- The case of Tanzanian

2004 – Tanzania made consultations with neighbors: Kenya, Uganda, Burundi, Rwanda, Zambia, Malawi, DRC, Mozambique on Digital Plan

Produced coordinated national draft plans for consultation at African Regional Broadcasting Conference and final submission to RRC 2004 (digital TV draft conference)

2005 – Consultation with stake holders at Annual Broadcasting Conference (ABC)

1st PCD on migration from Analogue to Digital Broadcasting; July 2005

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) 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) 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 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)

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!
