NRSC Announces New PI Codes for FM Translators

RDS Usage Working Group resolved a metadata issue December 6, 2017

WASHINGTON — The National Radio Systems Committee has introduced a unique Radio Data System Program Identification code for U.S. FM translators, Alan Jurison announced on the NAB Pilot website in late November.

Jurison is chair of the RDS Usage Working Group at the National Radio Systems Committee and also serves as iHeartMedia’s senior operations engineer.

He explains that one type of metadata transmitted by RDS subcarrier is the PI code, which is used by the receiver to uniquely identify the audio program being broadcast by the FM station. In the US, the PI code has historically been derived from a radio station’s call sign, which is complicated by FM translators.

To resolve this issue, Jurison writes, “the NRSC’s RDS Usage Working Group developed a new algorithm just for FM translators, which can assign a unique PI code to each FM translator in the US. This algorithm has been implemented using a web-based tool and a list of PI codes for all FM translators in the US is now available at http://picodes.nrscstandards.org/.”
