A report on the latest field trials of SFN technology recently completed as part of Phoenix Model Market testing shows large improvements in signal level and service margin were found in nearly all test locations when single frequency network nodes were both transmitting. Error-free reception was improved in approximately 80% of the sites.
Erik Langner, president of Signal Infrastructure Group (recently rechristened from Public Media Group), has been working to identify potential applications for broadcasters’ ATSC 3.0 data pipe. Those include targeted advertising, sending software updates to IoT or auto manufacturers and public health, safety and education organizations.

The concept of operating two or more transmitters on the same frequency in the same geographic region is not new, but there’s considerable talk within the industry about the role of similar technology in the widespread deployment of ATSC 3.0, particularly after the FCC’s January decision to ease rules on DTS “spillover” that the commission believes will help NextGen TV reach its full potential.
To take full advantage of the new broadcast standard, broadcasters have begun work on single frequency networks in Dallas and elsewhere that pump broadcast signals into strategic areas of a market to make sure they reliably reach smartphones and other mobile devices.
From repacking TV spectrum to make way for wireless companies to the next-generation ATSC 3.0 television transmission standard; from IP-based workflows to news technologies and workflows, the television industry expended a lot of time, money and effort this year to position itself for where it must go. This is Part 3 of TVNewsCheck’s annual Year in Review for 2015. Part I, which appeared Monday, reviewed the year’s happenings in local and broadcast network news. Part 2, which ran Tuesday, recapped the year’s highlights in business, regulation, syndicated and broadcast network programming and new media. And Part 4 on Thursday will remember the electronic media luminaries who died during 2015. Read all of the 2015 Year in Review stories here.
