There is a choice, therefore, between simple error detection which will not recover
the message and full error correction which will do so.
From the results of reception tests carried out in Sweden, it would seem that the
optimum decoding strategy, both for domestic as well as in-car reception, requires
correction of single errors and adjacent double errors and the detection of long error
strings.
The application of the error detection and correction code is however left to the receiver
manufacturer.

4.4 Applications
Radiodata (RDS) has been developed principally for transmitting tuning information,
such as the channel identifier, for the control of radio networks and the control of
basic functions of the new generation of radio receivers. It also, however, offers basic
ARI functions for in-car reception besides many interesting possibilities for domestic
radio reception.
