Successful DTV reception depends more on received signal strength than on modulation scheme or receiver quality, according to in-depth report by Advanced TV Systems Committee (ATSC) Task Force on RF Performance. Report suggests that perceived DTV problems may be result of inflated expectations, that broadcasters shouldn’t count on receiver improvements to solve any problems and that signal improvements, such as use of on-channel receivers, could provide big reception improvements.
Advanced TV Systems Committee (ATSC) said its RF Task Force had completed work on DTV radio signal performance technical issues. Work included performance assessment of ATSC transmission system, ATSC Exec. Dir. Mark Richer said.
