GARLAND, TEXAS AND HUNT VALLEY, MD. —Earlier this year, TV Technology first reported on the combined effort of several broadcast related organizations, including Sinclair Broadcast Group, its ONE Media innovations division, and American Tower, in building the world’s first single frequency network (SFN) using ATSC 3.0 technology in the Dallas/Ft. Worth (DFW) television market. The plan—which was devised last fall—is to deploy the new transmission technology initially on an experimental basis, and when the last bit of data has been gleaned and reports prepared, to move forward on finalizing the SFN as a permanent component of the television delivery infrastructure for viewers in that market.
