HD Radio Rules Take Effect September 14, 2007
August 22, 2007
Introduction
The FCC's HD radio rules are to take effect September 14, 2007. Subject to the limitations noted below, AM stations will be able to broadcast HD at night and FM stations can operate HD2 and HD3 streams without a need for special authorization.
At this point, HD radio remains a "hybrid" IBOC (in-band, on-channel) system that permits the transmission of both analog and digital signals within the spectrum occupied by a single AM or FM channel. Among the benefits of the digital carriers that can be added to a station’s analog signal are improved fidelity and reception, added information services, and compatibility with existing receivers (although new HD-capable receivers, currently scarce and expensive, are needed to receive the digital streams).
The Commission anticipates moving toward an all-digital radio service, but intends to rely upon marketplace forces in lieu of a timetable or a formal conversion policy. This seems particularly appropriate since, unlike HDTV, the IBOC technology neither requires new spectrum nor frees up existing radio channels for other uses. The Commission plans to explore technical and policy issues germane to an all-digital radio environment, but once HD receiver penetration reaches a critical mass.
