Analog Radio
Published in Skip Pizzi, Graham A. Jones, A Broadcast Engineering Tutorial for Non-Engineers, 2014
The RDS signal can carry up to about a dozen different types of data related to the station and its content, such as station identification, station format, song titles, artist names, and other program- or station-related information. It can also accommodate other text such as weather and traffic updates, or emergency alerting. RDS data can be displayed as static or scrolling text on a receiver's display panel. It has allowed analog FM broadcasters to add metadata to describe their services and/or content, and thereby compete with digital services that inherently include such additional descriptive material.
An Introduction To HD Radio Technology

Additionally, title and artist data, called program associated data (PAD) or alternatively, program service data (PSD), is transmitted in both the AM and FM HD Radio systems. Analog FM already has the ability to transmit this information via the radio data systems (RDS), which operates on a 57-kilohertz (kHz) subcarrier in the FM baseband. PAD will be a new experience for AM HD Radio listeners, as their radios have the ability to display title and artist information for the first time.
General Managers' Overview

RDS is the Radio Data System. RDS is the name of the European standard as well. In the U.S., the standard is called the Radio Broadcast Data System, or RBDS, but for your listener, the technology is always referred to as RDS. RDS is a method of transmitting program-related data inaudibly on a 57 kHz subcarrier. The following question and answer section will answer the questions most important to you. Abbreviations particular to RDS are shown in parentheses for reference.

RTTI providers can use data from the primary stationary detectors, which in most cases are owned by the government, for broadcasting messages. However, new methods for measuring speeds and travel times such as the floating car data and floating phone data now enable private service providers to offer their services without necessarily having to rely solely on detector data. The data gathered from different sources are then fused. In Germany, service providers process the available data, integrate, and transmit them to the vehicles, smart phones, and so on of the customers through traffic message channel (TMC) technology. The processed traffic information is digitally coded into radio data system (RDS) and transmitted via conventional FM radio broadcast. It can also be transmitted on digital audio broadcasting (DAB) or satellite radio (Wikipedia, 2016). RDS-TMC can embed only a small amount of digital information.

RDS is a data broadcast protocol which carries digit data using the sub-carrier of FM radio, and its first version was published by the European Broadcast Union. Figure 1 shows the baseband coding structure of the RDS.
