Tanzania Communications Regulatory Authority Migration from Analogue to Digital Broadcasting Presented by: Eng. Taha A. Usi Consultant Broadcasting Affairs TCRA tahausi@tcra.go.tz
Agenda • Background • Why digital broadcasting ? • Features of Digital Terrestrial Television • Strategy • Implementation Issues • Challenges • Conclusion
Background • International Scene • 1990’s First Tests on Digital Broadcasting – Europe • 2000 Adoption of Digital Broadcasting in Europe and USA • 2004 ITU consultations on Digital broadcasting at international level
Background Cont .. (2) • RRC -2004 • ITU consultations on Digital broadcasting for regions 1 and part of region 3 of ITU member administrations. • Draft digital plan was produced for the whole planning region • Prior to takeoff of RRC – 2004 Conference; consultations and coordination were made on the individual draft national plans, among regional groupings of member administrations
Background Cont .. (3) RRC – 2006 • ITU coordinated Conference on Digital Migration. • Adoption of Digital plan. • Adoption of Digital Migration Strategies and Principles. • Revision of GE 89 analogue plan • Two Analogue cut off dates:2015 UHF band; 2020 VHF band
RRC06 Planning Area for region 1 • Region1:Europe, Middle East, Africa.Region2:AmericasRegion3:Asia, Pacific Region 6
Background cont…(4) WRC –2007 • Stressed on the need of Digital Dividend. • 790 – 862 MHZ (IMT 2000) ie Channel 61 – 69 of the Broadcast band) • Concretize on the plan • Confirmation of cut off deadlines 2015 and 2020
Why Digital Broadcasting ? • Information can easily be coded ANALOJIA DIGITALI
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 (see next slide)
Why Digital Broadcasting ? Cont ..(3) More channels Analogue Transmitter Digital Transmitter Ch 1 Ch 2 Ch 1 Ch 3 Ch 4 Ch 12; 16; 20 8 MHz channel; One service; New frequency per site 8 MHz channel; 6 or more services; Same Frequency re-use in SFN
I book my holidays… I manage my bank account… I do my shopping… I choose a movie for tonight… Why Digital Broadcasting? cont..(4) • Supports Multimedia services Digital Tv
Why Digital Broadcasting? Cont.. (5) High Quality and more details Aspect ratio: 4:3 Aspect ratio: 16:9 KAMATI YA BUNGE MAENDELEO YA JAMII_KUUELEKEA DIGITALI_12-07-2009 12 07/23/09
Features of DTT • Standard • DVB – T (region 1 and part of region 3) • Reception Mode • Networks: MFN; SFN • Multimedia nature
Features of DTT Cont.. (2) 1 2 5 4 3 Encoder Satellite feeds Encoder Studios c) Signal feed MUX DVB-T Server Other feeds DVB-T IPDVB Encoder Internet Service d) Broadcasting MHP Interactive Services a) Network Management System b) Multiplexing: Another feature of Digital Terrestrial TV
Features of DTT Cont.. (3) • Possible distribution modes: • Satellite • Cable- fiber • Microwave for short distances (see following slide)
Digital Terrestrial Transmission Chain Fiber cable
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)
Implementation Issues- The case of Tanzanian Cont .. (2) • 2005 – Consultation with stake holders at Annual Broadcasting Conference (ABC) • 1st PCD on migration from Analogue to Digital Broadcasting; July 2005 • 2nd PCD on migration from Analogue to Digital Broadcasting; August 2006
Implementation Issues- The case of Tanzanian …(3) • 2006 – Further consultations with stakeholders at ABC – Dec. 2006 • Formulation of migration plan on Establishment of Multiplex Operators • Recommended: • Two CMUX and one PMUX • Phased implementation • MUX to operate under Network facility licensing category
Implementation Issues- The case of Tanzanian Cont .. (4) • 2007: Consultation with Stakeholders • 2007: Consultation with Government • 2008: Meeting of the National Technical Committee on Digital Migration • 2008: Instituting guidelines to be followed in the implementation of digital broadcasting
Implementation Issues- The case of Tanzania Cont .. (5) • 2008 Licensing of MUX process started: • Expression of Interest and Request for Proposal for securing MUX • Service Level agreements verification • By First part of 2009 to have MUX in place • Public Awareness Campaign 2008/2009 financial year • Cabinet Approval
Implementation Issues- The case of Tanzanian Cont .. (6) • Public Awareness Campaign financial implication: • Budget for 6 years, 2010 to 2015 :- • Details of the budget are being worked out
Implementation Issues- The case of Tanzanian Cont .. (7) • Specification of Set Top Box • Importation of Set Top Box • Simulcast plan to start 2009 • Digital (National) plan ready • Simulcast cut off date 2012 • Switch off Date of Analogue 2015, May • Switchover to full Digital 2015 June
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!
