Las Vegas - Apr 12, 2008 - The National Radio Systems Committee (NRSC) has adopted an updated version of its in-band/on-channel (IBOC) digital radio broadcasting standard. NRSC-5-B, 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, director of research and development, Digital Broadcast, Kenwood Americas Corporation. This latest version includes some editorial updates as well as a revised FM IBOC RF mask that was submitted to the NRSC by Ibiquity Digital Corporation, developers of the HD Radio technology upon which NRSC-5-B is based.

The document will be available to the public through the NRSC website following a final, procedural review that will take approximately four weeks.
