NPR Labs has launched an interactive online mapping system, reports Radio World, to give pubradio and pubTV stations a better idea of analog and digital coverage of their signal in cars, on mobile handheld devices and indoor receivers. NPR Labs Senior Technology John Kean told the site that the system allows overlays to compare analog and HD radio at original and higher FM power levels. The DTV coverage, especially for mobile devices, will predict how well viewers can receive full service and translator systems. The ATSC-M/H coverage was developed with assistance from the Open Mobile Video Coalition. “The demographic data is ideal for gauging and comparing coverage for actual populations, which planners and underwriters may use,” Kean said. The system is free and works best with online browsers such as Chrome, Firefox and Internet Explorer 9 and above.
