A method and device for the transmission of additional data in an analog radio transmission system, wherein the additional data also contains information relating to alternative transmission frequencies of a respective program, and the alternative transmission frequencies relate to digital radio transmission systems. The alternative transmission frequencies for digital radio transmission systems are transmitted in an amplitude modulation data system (AMDS) format by transmitting said service description channel data (SDC) by mapping into the AMDS format.
La présente invention concerne un procédé et un dispositif pour transmettre des données supplémentaires dans un système de transmission radio analogique, les données supplémentaires contenant des informations relatives à des fréquences d'émission alternatives du programme respectif, et les fréquences d'émission alternatives concernant des systèmes de transmission radio numériques. Les fréquences d'émission alternatives destinées aux systèmes de transmission radio numériques, sont transmises dans le format AMDS (Amplituden Modulation Data System / système de données à modulation en amplitude), alors que ces données SDC (Service Description Channel / canal de description de service) sont transmises par mappage dans le format AMDS.
