NRSC Updates IBOC Digital Radio Standards

Updated Standards

THE NATIONAL RADIO SYSTEMS COMMITTEE (NRSC), co-sponsored by the NATIONAL ASSOCIATION OF BROADCASTERS (NAB) and THE CONSUMER ELECTRONICS ASSOCIATION (CEA) has 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.

"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 NAB EVP/CTO KEVIN GAGE. "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.

The updated Standard will be available free-of-charge on the NRSC's website at www.NRSCstandards.org, 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.
