Process of turning off the analogue terrestrial television
signal and replacing it with a digital signal
Government initiated policy, aiming at
– More channels and services
– New revenue streams and business models
The key objective in the ASO process is reducing the risk of
service interruption

Infrastructure &
Spectrum Compatibility
• Incompatibility only if:
– Simulcast
– Lack of Spectrum
Antenna space
Floor space
• Infrastructure
incompatibility:
Transmitter Space
– Lack of antenna space
– Lack of floor space
– Lack of power & cooling
• Resolving spectrum is
trading off:
– Continuing analogue TV
– Best digital coverage

Infrastructure principles
Floor & Antenna Space
• Reduce gain &
increase power
• Reduce power &
increase gain
• Pre-fab containers
(feeder cable loss!)
• Reduce power & gain
• Increase robustness
• Reduce coverage
Spectum principles
• Lowering A ERP
Improving Digital
Degrading Analogue
ITU Workshop on digital television

• Increasing D
robustness
• Reducing D coverage
• Allow more D
interference

ASO Communication Plan
• ASO strategy is phased in stages
• ASO target groups
– Viewers (including disabled, elderly
people, community centres, landlords,
public places, etc)
– Industry (including STB producers,
retailers, broadcasters, local
Governments, consumer associations &
certification institutes)
• Communication tools

Conclusions ASO
• ASO is Government initiated and led process:
– Government is responsible for DTV service (& levels)
– Government will incure (significant) costs
• ASO key decisions are:
– Simulcast or not
– When, where and how long
• ASO process requires timely & careful planning, esp.
when simulcast & infra/spectrum incompatibility exist
• ASO Key Success Factors:
