NRSC Updates IBOC Digital Radio Standard

WASHINGTON, DC/ARLINGTON, VA -- The National Radio Systems Committee (NRSC), co-sponsored by the National Association of Broadcasters (NAB) and the Consumer Electronics Association (CEA), today adopted an updated version of its in-band/on-channel (IBOC) digital radio broadcasting standard, NRSC-5-C. The new version includes more than 70 modifications that address improvements and refinements to the HD Radio system benefitting both broadcasters and listeners.

"The NRSC is to be commended for its hard work in developing this important update that includes improvements to the HD Radio system that will benefit broadcasters as well as the listening public, as they provide for a more robust digital signal and improved coverage area," said Kevin Gage, executive vice president and chief technology officer, NAB. "NAB is a strong supporter of the transition to digital radio and looks forward to its continued success."

The more than 70 modifications in this new version include the ability to use asymmetric sidebands, new modes of operation, and updated RF masks. A major part of this work has been the update of "reference documents" by iBiquity Digital Corporation, which contain the technical details of the standard.

"HD Radio technology is gaining momentum in the marketplace," said Brian Markwalter, senior vice president of research and standards at CEA. "Recent announcements from automakers like Toyota, Lexus and Kia indicate that more consumers will be using this technology in their cars, and today's improvements to the standard will make the consumer experience even better."

NRSC-5-C, In-band/on-channel Digital Radio Broadcasting Standard, was adopted by the Digital Radio Broadcasting (DRB) Subcommittee, which is co-chaired by Andy Laird, vice president and chief technology officer, Journal Broadcast Group, and Mike Bergman, vice president of new digital technologies, Kenwood USA. It was developed by the subcommittee's IBOC Standards Development Working Group (ISDWG), which is chaired by Dom Bordonaro, chief engineer, Cox Broadcasting - Connecticut.

The updated Standard will be available free-of-charge on the NRSC's website, following a final, procedural review that will take approximately two weeks. Additional information about the NRSC, including information on becoming a member, is also available on the website.
