4.1 General
The RBDS standard uses the same data modulation as in IEC 62106.1. It also uses the same RDS features and group type coding as in IEC 62106-2. Open Data Applications coding and registration for application identification are specified in lEG 62106-2 and IEC 62106-3, respectively. Any exceptions for RBDS to these specifications are described in 4.2.
4.2 Exceptions
4.2.1 P1 coding
The P1 code nibbles are composed differently. The methods used are described in Annex A.
4.2.2 PTY coding
The 5-bit PTY codes are defined with a different meaning in RBDS. The code definitions given in Annex B shall be used for RBDS.
4.2.3 PS
For RBDS, there is no prohibition on using PS for displaying sequential information and there is no requirement that PS be static. For RBDS, there are no restrictions on the content or update rate of the PS field.IEC 62106-9 pdf download.
