RT+ has been designed to let the listener (or user) derive additional
benefits from the RDS RadioText service. It enables FM RDS
receivers to “understand” the RadioText – to recognize designated
objects, to make those objects manageable by the user and thus
offer the user direct access to specific elements of RadioText
messages. Such an element can, for example, be programmeassociated metadata such as the Title and the Artist of the currently
playing song, or it can be news headlines. This provides the listener
with an “mp3-player feeling” while listening to analogue FM radio. The elements can also carry additional service messages or information about the Radio Station such as the telephone number or the
web address of the Radio Station’s hotline. A full list of the RT Content types can be found at [1].
