Abstract:
1. An FM transmitter, comprising: a processor configured to identify text data providing ancillary information descriptive of digital audio signal responsive to receiving a data type, to convert the selected text data into digitally encoded speech, and to encode the digital audio signal and the digitally encoded speech according to an FM standard into an FM digital signal responsive to receiving a transmission mode; a converter configured to convert the FM digital signal into an analog FM signal; and a transmitter configured to transmit the analog FM signal; wherein the data type is configured to identify a type of ancillary information that is descriptive of the digital audio signal; wherein the transmission mode is configured to identify a mode in which to encode the digital audio signal and the digitally encoded speech such that the digitally encoded speech is annunciated after decoding responsive to the transmission mode; and wherein the processor includes a signal combiner configured to time-division multiplex the digital audio signal and the digitally encoded speech to generate the FM digital signal responsive to the transmission mode.
