ASO will help full DVB-T deployment in Europe BEFORE ASO, 100% coverage with DVB-T is exceptionnally possible... AFTER ASO, Full coverage with DVB-T Becomes a target for 2012 ! 100% Digital TV reached With T+C+S platforms In some countries ! 100% 100% 100% 100% 95% 80% 100% 99% 90% 80% 100% 100% 90% 83% 85% 95% 100% 100% Source Digitag (www.digitag.org) 95% 85% 96% 85% SET'08 Conference - Post Analog Switch-Off Forecast in Europe
