Changing the rules to allow broadcasters to set up SFNs on the edges of their station contours would improve coverage throughout station coverage areas, increase spectrum efficiency, and reduce the need for TV translators, they said. NAB and APTS want the FCC to seek comment on redefining station coverage areas to allow DTS transmitter signals to reach outside the service area of a station’s central transmitter, so they can better fill in gaps in the edges of an outlet’s coverage. The rule change won’t result in more interference for low-power TV stations, the groups said. “Stations could enhance service to viewers by improving coverage throughout their service areas and offering improved mobile coverage without the risk of encroaching on the service of stations in adjacent markets.” Fletcher Heald broadcast attorney Peter Tannenwald said more flexibility for DTS is probably a good thing for the public, but that it’s not clear what the proposal could mean for LPTV. Low-power s could lose some viewers outside their protected contour to interference from DTS transmitters, he said. “If the FCC encourages DTS to replace translators, new channels could open up that would benefit LPTV stations.”
