Data Services and Metadata (DSM) Subcommittee

The DSM Subcommittee develops standards and guidelines for digital information that radio broadcasters send to their audiences via the growing number of data transmission technologies in use today.  This Subcommittee focuses on data (content and metadata) protocols, in contrast to the NRSC DRB Subcommittee which principally focuses on the transmission aspects of in-band/on-channel AM and FM digital radio systems.

This Subcommittee owns and maintains the body of work from its predecessor, the NRSC Radio Broadcast Data System (RBDS) Subcommittee. This Subcommittee also has responsibility for working with other standards bodies in this area of focus, specifically including the RDS Forum and the International Electrotechnical Committee for the maintenance of the Radio Data System (RDS) Standard currently embodied as IEC-62106.
