Abstract (en)

[origin: WO2006003063A1] 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.
