  1. 1. Transition to Digital Television (DTV) Advantages, Implications & Challengesg p g Javid HamdardJavid Hamdard ICT Consultant – Internews Network 11 November, 2012
  2. 2. Backgroundg • Analogue terrestrial TV has been around for more than half a century beginning in 1927 inmore than half a century beginning in 1927 in the USA (1964 in Afghanistan). • As per the ITU’s (RRC-06) agreement all member countries (including Afghanistan) are required to switchover to DTV by June switchover to DTV by June 2015. • Post June 2015, ITU or any originating country/entity is not responsible for any cross- border interference with any existing Analogue spectrum/frequencies in use + Int. compatibilityp / q p y etc. 2
  3. 3. Introduction • In simple words, Digital Television (DTV) is a more improved and efficient medium to broadcastimproved and efficient medium to broadcast multimedia content compared to Analogue terrestrial TV. • In Digital broadcasting (DTV) multi-media content (Images, Sound, Text..) are transmitted in a high quality compressed format allowing a broad range of services/content to bebroad range of services/content to be broadcasted and delivered in less space (Spectrum). 4 – 8 Programs per single Analogue Frequency/Channel. 3
  4. 4. Standards and Platforms • Standards: The three most common standards are DVB C (cable TV) DVB T (old version) DVBare DVB-C (cable TV), DVB-T (old version), DVB- T2 (latest version). Afghanistan will most probably go for DVB-T2. • Platforms: There are four common service provision and access Platforms: 1. Digital Terrestrial Television (DTT). 2 Digital Cable2. Digital Cable. 3. Digital Satellite (D-Sat). 4. DSL-DTV. 4
  5. 5. Worldwide Transition Status Transition completed, all analog signals terminated. Transition completed for full power stations, not yet completed for low power stations.p p , y p p Transition in progress, broadcasting both analog and digital signals. Transition not yet started, broadcasting analog signals only. Does not intend to transition, broadcasting analog signals only. No information available. 5
  6. 6. Advantagesg • Government: 1. Compliance with the ITU mandate (frequency re-organization, futuristic,mandate (frequency re organization, futuristic, Intl. coordination), 2. More Frequency (more broadcasters/channels, more content, more $$ ) 3 Wid C 4 B ttrevenue $$ ), 3. Wider Coverage, 4. Better Regulation and Monitoring. • Broadcasters: 1 Wider Coverage 2• Broadcasters: 1. Wider Coverage, 2. Infrastructure Efficiency, 3. Multicasting, Better QoS, Competition (All in All more $$).p ( ) • Users/Consumers: 1. Better QoS, 2. More programs/channels/content = more choices, 3.

  7. 7. Implicationsp • Government: Strategy, Consultation, Education Regulations/Legislation Spectrum Planning andRegulations/Legislation, Spectrum Planning and Coordination (National & Intl.), Monitoring and Coordination, Investment (Full/Part). • Operators/Broadcasters: Infrastructure cost (network-operators), Studio and Equipment( p ) q p upgrade cost, Competition cost (quality of content, production/local content). • Users/Consumers: Awareness, Equipment Upgrade cost (STB etc) , Additional Service C tCost. 7
  8. 8. Challengesg • Huge Investment. • Nationwide Awareness and Education. • Legal and Regulatory Framework.g g y • Multi-Stakeholder coordination & cooperation. i i• Technical Preparations. • Business Model/s. • Transition Methodology. Transition Frustration• Transition Frustration. 8
  9. 9. Best-Practices • Consultation, Awareness and Education. • Strong Leadership. • Close Coordination and Cooperation. • Identifying Appropriate Business Model. • Gradual Phase by Phase Roll-outGradual Phase by Phase Roll out. • Consumer Oriented/Friendly Approach/Policies.
