Method and device for transmitting complementary data in an analog radio transmission system, the complementary data including information with respect to alternative transmitting frequencies of the respective program, and the alternative transmitting frequencies relating to digital radio transmission systems. The alternative transmitting frequencies for digital radio transmission systems are transmitted in the AMDS (amplitude modulation data system) format, in that these SCD (service description channel) data are copied into the AMDS format, using mapping.

Method and device for transmitting complementary data in an analog radio transmission system

A method for adjusting transmission parameters of a transmitter for digital radio signals, for example, broadcast signals, is described, in which context a receiving apparatus receives the digital radio signals emitted by the transmitter and transfers data to the transmitter via a return channel, transfer data and reception parameters being contained in the data. The transmitter then optimizes the transmission parameters as a function of these data. It is possible in this context that in the data, the transfer data either contain the received digital radio signals, or already have evaluation data from the receiving apparatus. The method is suitable in particular for digital radio signals that are transferred below 30 MHz. The return channel is operated either in simplex mode from the receiving apparatus to the transmitter, or in duplex mode.

Method for adjusting transmission parameters from a transmitter for digital radio signals

A method for transmitting traffic announcements via Digital Audio Broadcasting (DAB), making use of the TMC code, where it is possible to have a simple allocation of the audio signals to the TMC data. In this context, the allocation is predetermined by the data frame of the digital transmitter and by the corresponding data protocol.
