FCC Initiates Rulemaking Proceeding for DTS Flexibility to Support ATSC 3.0

The FCC has adopted a Notice of Proposed Rulemaking seeking comment on certain technical rule changes that would give TV stations greater flexibility to use distributed transmission systems (DTS) as ATSC 3.0 is deployed.  DTS uses two or more synchronized, same-channel transmission sites in a station’s service area to improve indoor and mobile reception.  Part of the rulemaking would allow minor expansions of DTS service areas beyond a station’s existing coverage, which could impact neighboring stations and low power or TV translator stations, which are secondary.  Comment deadlines have not yet been set.
