8. Viewers’ Preparation Towards Digitalization
DTV Support Centers
(Established by Ministry of Internal affairs and Communications)
Overview: 　　Established by Government Nationwide
　　Help Viewers for Digital TV Reception
How: 　　Notification and Announcement from the DTV Centers
Main Players:　Local governments, Retailers, and Broadcasters
More Than 100 NHK Engineers Dispatched
as Team-Leaders at “DTV Support Center”

9. DTV Support Centers Briefings for senior citizens
(2) Visits to Elderly Peoples
(Visits to more than 2 million homes)
(3) Vehicle for measuring signal quality
(Publishing of findings)
(4) Call Centers (Max. 1,200 operators)
“Quick Radio measurement”
Good reception along roads highlighted in blue

10. Three Major Difficulties of Reception Infrastructure
Houses (3.4 million)
Apartments (5.8 million)
① Change VHF Antennas to UHF
UHF
VHF
Changing Antennas for VHF to UHF required in the Area where Analog TV Service was on VHF
(Approx. 9.2 million households)
② Rural Area Reception
Community Reception Antennas are Needed for Rural Area
(Approx million households)
③ Interference Caused by Building Shadows
Technical Surveys and Agreement for Cost Sharing Required
(Approx. 8 million households)
Both Government and NHK Worked Closely for Solutions in Financially and Technically 9
