Audio Distribution System 

  Crestron Adagio™ AADS

Many radio stations transmit additional information, such as traffic information, 
radio text, real time clock etc., with their regular FM programming. The FM tuner 
contains circuitry that retrieves this information. 

The US format for such information is called the Radio Broadcast Data System 
(RBDS), and in Europe this format is called the Radio Data System (RDS). There are 
some differences between the US and European standards. 

The tables in this appendix describe information included in the standard. 

This information can be viewed on APAD devices that are connected to the AADS.
