Radio text

from Wikipedia, the free encyclopedia

Radio text are of the radio station transmitted additional data stored in the display -capable radio text of a radio ( RDS Receivers) are displayed. This can be, for example, the station name, the title and artist of the current song or the latest news. Via VHF , radio text is a function of the so-called radio data system . Not all RDS-capable VHF radios also support the radio text, so that some radio providers misuse the program service name (PS) in order to transmit an accompanying text (pieced together).

Radiotext is not only used in RDS-capable VHF radios, but was also broadcast on some radio programs broadcast via satellite in the Astra Digital Radio format. In DVB-S format, too , the radio text is displayed either on the television or in the display of the satellite receiver, depending on the device type. In the digital radio standard DAB there is an equivalent to radio text with Dynamic Label .

Radiotext plus

Since 2005, Radiotext has been developed into Radiotext plus ( RT + ), the first standard of which was published in several versions between 2005 and 2008. RT + has now also been integrated into the current RDS specification EN 62106: 2010-07 (German version).

RT + differs from Radiotext in that it was primarily designed for the use of mobile devices with limited displays. Contents of the RT + are provided with so-called category tags, with which the software of the recipient can filter certain contents. In terms of content, the normal radio text information and the RT + content can be mixed, the RT + compatible receiver automatically filters the relevant data from the complete stream. RT + compatible ( car radio ) receivers usually have separate display areas on which RT + is continuously displayed without first activating radio text. Main use is z. B. the display of the current title / artist or similar additional information about the program. The category filter also prevents irrelevant information from being displayed and it also serves to make the information legible in mobile operation, since not every information is output, thus increasing the service life.

Analogous to RT +, DAB has the Dynamic Label Plus extension with a similar function, which is equivalent to RT.
