Each frame corresponds to a group in the RDS specification. The information words from the four blocks in the group appear first, in big-endian byte order, followed by an encoding of the offset words from the four blocks in the group.
The offset words contain a value that is one of:
- 0, for offset word
A
; - 1, for offset word
B
; - 2, for offset word
C

D
