    Abstract: A method comprising: at an importer of an IBOC digital radio broadcasting system: establishing a data link to an audio client configured to buffer audio from an audio source over a buffering duration, to produce buffered audio; receiving, from the audio client, an indication of the buffering duration; identifying a logical channel of an IBOC waveform assigned to the audio client and configured to transmit PDUs of the audio at a PDU rate; computing a quantized number of PDUs that is greater than one into which the buffered audio is to be divided at the audio client based on the buffering duration and the PDU rate; sending, to the audio client, an indication of the quantized number of the PDUs; and upon sending importer data requests to the audio client over the data link, receiving, from the audio client, client data responses each including the quantized number of the PDUs.

    Abstract: A data link manager includes a User Datagram Protocol (UDP) receiver for receiving HD Radio broadcast equipment communication protocol (HDP) data or non-HD Radio broadcast equipment communication protocol (non-HDP) data using a User Datagram Protocol/Internet Protocol (UDP/IP) protocol; a Transmission Control Protocol (TCP) receiver; and a router for receiving data from the UDP receiver and the TCP receiver, for searching for a destination route in a routing table, and for forwarding the data received from the from the UDP receiver and the TCP receiver to an identified destination route.

    Abstract: Methods and systems for synchronizing audio transmission in a single frequency network. Aspects of a method include preparing in a first exporter a first digital audio signal for transmission to a first exciter engine; buffering the first digital audio signal and transmitting the buffered first digital audio signal to the first exciter engine; preparing in a second exporter a second digital audio signal for transmission to a second exciter engine; buffering the second digital audio signal; transmitting the first digital audio signal from the first control unit to the second control unit; receiving control commands regarding a buffered first or second digital audio signal, wherein the second control unit transmits the buffered first or second digital audio signal dependent on the received control commands; and synchronized transmission of the buffered first digital audio signal and the buffered first or second digital audio signal based on a received trigger signal.
