There are regional variations in the RDS specification,
- RDS which is the international standard, and
- RBDS which is the variant used in the United States.
And if that's not enough there's a new RDS 2.0 on the horizon which will be supported should it ever be implemented in the world outside of committees. If you want to know more about RDS please visit the RDS Forum where you can purchase a copy of the RDS specification.
This software implements almost all features of the current RDS specification.
By default RDS data is displayed as a waterfall picture-in-picture (PiP). You enable this display either from the ribbon bar's View panel or from the program options.
There are areas in the RDS decoding where I can improve the decoding - this will not make a great improvement but every little tweak helps.
