NRSC Releases Study on Program Associated Data

Analysis of Artist, Song and Album Title data will assist broadcasters and receiver manufacturers in bringing PAD to consumers

WASHINGTON, DC/ARLINGTON, VA - The National Radio Systems Committee (NRSC) today released a new report which presents the results of a quantitative analysis on Program Associated Data (PAD), specifically on the number of characters needed to display song title, artist name and album title fields. The NRSC is a technical standards-setting body co-sponsored by the National Association of Broadcasters (NAB) and the Consumer Electronics Association (CEA).

NRSC-R300, Program Associated Data (PAD) Field Length Study, was developed by the Radio Broadcast Data System (RBDS) Subcommittee, chaired by Barry Thomas, vice president of engineering, Lincoln Financial Media. The principal effort was conducted within the Subcommittee's RDS Usage Working Group (RUWG), chaired by Steve Davis, senior vice president, Engineering and Capital Management, Clear Channel Radio.

An extensive PAD database developed by Clear Channel Radio was used as the basis for this study, from which over 149,000 program items were considered. The resulting Artist, Title and Album string lengths analyses are summarized in the Report using histograms and cumulative distribution functions (CDFs). This information is applicable to PAD usage in both HD Radio and RDS systems, and will help broadcasters and receiver manufacturers understand how to best transmit and display PAD.

This new NRSC Report is available free-of-charge on the NRSC's website ( Additional information about the NRSC, including information on becoming a member, is also available on the website.
