Abstract: An audio delivery system (100) can include an alert processor (108) configured to parse alert content. The alert processor can receive first data representing the alert content. The alert processor can convert the alert content to an alert message that includes alert text and parameters. A connected radio server (120), coupled to the alert processor via internet protocol, can insert the alert content into a data stream. The connected radio server can receive second data representing the alert message from the alert processor via internet protocol. The connected radio server can receive instructions from the alert processor via internet protocol to incorporate the alert message into the data stream. The data stream can include an audio stream and the alert message. The connected radio server can provide the data stream to a connected radio receiver (102) via internet protocol.

Abstract: Service modes specify how digital content is formatted in sidebands of an FM radio channel. In an improved service mode, encoded bits can be distributed between an in-band encoded component and a cross-band encoded component, where the encoded bits in the in-band encoded component are desynchronized by a specified duration with respect to the encoded bits in the cross-band encoded component. The encoded bits in the in-band encoded component can be allocated into frequency partitions that are used by a legacy service mode, such as MP1 or MP3, which can provide backward compatibility with the legacy service mode. The encoded bits in the cross-band encoded component can be allocated into frequency partitions that are not used by the legacy service mode, and are found in the opposite sideband, compared with the legacy service mode, which can provide time diversity within a single sideband.

Abstract: Enhanced digital broad cast signals are transmitted on a digital radio broadcast signal by allocating spectral resources of the digital radio broadcast signal to simultaneously serve existing receivers (which can decode default content but not new content from the enhanced digital broadcast signal) and new receivers (which can decode default content and can decode new digital content from the enhanced digital broadcast signal) by modulating a first plurality of reference subcarriers with a first signal constellation, and modulating a second plurality of reference subcarriers with a second modified signal constellation such that a receiver processes the digital radio broadcast signal to produce a first coherent reference signal estimate for the first plurality of reference subcarriers to extract the default content for playback and to produce a second coherent reference signal estimate for the second plurality of reference subcarriers to disregard the new content.

Abstract: A method of block deinterleaving data received at a digital radio broadcast receiver is described. The method includes providing a block of memory having a n×k addresses, wherein the block comprises a single table, receiving a digital radio broadcast signal at the receiver, and demodulating the digital radio broadcast signal into a plurality of interleaved data units. For at least one series of n×k data units a pointer step size is determined, and for each data unit in the series, an address in the block is calculated based on the pointer step size, and an output data unit is read from the block at the address, such that said output data units represent block deinterleaved data units. An input data unit from the plurality of interleaved data units is then written to the block at the address. Associated systems and computer readable storage media are presented.

Abstract: A server includes a communication port connected to an internet of things (IoT) cloud, at least one hardware processor connected to the communication port, and memory including instructions. The instructions, when performed by the at least one hardware processor, cause the at least one hardware processor to perform operations comprising identifying, to a client application of a separate computing device, one or more available radio broadcast stations available for transmitting a message in a radio broadcast signal to one or more end devices of an IoT; receiving a message from the client application indicating one or more of the available radio broadcast stations for transmitting the message; and sending the encrypted message via the IoT cloud to one or more other servers included with radio broadcast automation equipment of the one or more indicated available radio broadcast stations.
