IEC 62106-4:2018 provides a number of tables for use in the implementation of the RDS system. This document specifies the procedure for registering a new value in an existing table or the registration of a new table.
IEC 62106-4:2018 together with IEC 62106-1, IEC 62106-2, IEC 62106-3, IEC 62106-5 and IEC 62106-6, cancels and replaces IEC 62106:2015, and constitutes a technical revision.

•    Provision has been made to carry RDS on multiple data-streams (RDS2).
•    The country identification table has been updated by adding some countries.
•    Translated PTY terms for 20 languages have been added.
