Appendix: RDS/RBDS Function Support
Many radio stations transmit additional information, such as traffic information,
radio text, real time clock etc., with their regular FM programming. The FM Tuner

are some differences between the US and European standards.
The tables in this Appendix describe information included in the standard.
