Digital in-band, on-channel (IBOC) radio, commercially known as HD Radio, has grown from its beginnings in the first decade of this century into a significant broadcast medium. The FCC’s Media Bureau lists 1,835 FM and 240 AM stations authorized to transmit the digital audio broadcast system, and the website of iBiquity Digital Corp., the technology’s developer, reports that every 4.5 seconds, a new car is sold with an HD Radio receiver. Listeners increasingly use HD Radio, and in dozens of radio markets, drivers depend on HD Radio to receive live traffic data. For radio multicast (HD-2 and HD-3) programming, over-the-air digital reception is essential.
This importance to broadcasters and listeners raises the question: “Is it time for HD Radio to receive allocations protection by the FCC?” This article describes the real technical effects on HD Radio reception and the potential impact on the current, analog-only allocations system. I will also describe the technology to adequately measure and report this impact, which was developed over several years with public projects supported by the Corporation for Public Broadcasting and the Public Telecommunications Facilities Program.
