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: In one embodiment, a receiver front end circuit can receive and process multiple radio frequency (RF) signals and output downconverted signals corresponding to these signals. In turn, multiple signal processors can be coupled to this front end. Specifically, a first signal processor can receive and process the downconverted signals to output a first signal obtained from content of a first RF signal, and a second signal processor can receive and process the downconverted signals to output a second signal obtained from content of a second RF signal. In addition, the apparatus may include a detection circuit coupled to the receiver front end circuit to detect presence of at least the second signal and enable the second signal processor responsive to the detected presence.

Abstract: A method is provided that comprises tuning a radio system to a frequency band that contains a locally-broadcast terrestrial radio signal. The locally-broadcast terrestrial radio signal comprising a main signal component and a side data component is thereby received. In response to receiving the locally-broadcast terrestrial radio signal a determination is made as to a permissible time for processing the side data component using a time slot schedule. The side data component is processed at the permissible time. A message corresponding to the side data component is outputted to an output device. In some instances, the side data component includes the message. In other instances, the method further includes searching a message lookup list using a code included in the side data component. When a stored code is found that matches the code, the message corresponding to the matching stored code is outputted.

Abstract: A method and system is presented for coordinating the transmission of supplemental digital data to accompany broadcast data, and in particular, analog radio broadcasts, among a plurality of broadcasters. The supplemental digital data may provide information about the particular broadcast data being transmitted or may be supplemental to such data. The supplemental digital data to be presented is sorted based on particular algorithms which may take into account broadcaster-specified criteria such as target audience, time of day, type of broadcast data presented, and the like. The supplemental digital data may be audio data, visual data, or audio-visual data for presentation with the broadcast data. The supplemental digital data may further be advertisement data. The advertisement data may be sold by the broadcasters or the party coordinating the IBOC transmission of the supplemental digital data. The supplemental digital data may play simultaneously with muted broadcast data or at a user-specified time.

Abstract: Embodiments may comprise radio data system logic to enter a sleep mode and wake periodically to receive a data packet. In several embodiments, the data packet is a Radio Data System (RDS) packet and the radio data system logic is RDS logic. Further embodiments may comprise radio data system logic to process the data packet to determine a first type field and to parse the first type field to identify a first indication. In several embodiments, parsing the data packet by the radio data system logic comprises parsing the data packet to determine a program type field and parsing the program type field to identify the first indication as an emergency alert indication. In response to identifying the first indication as a trigger, many embodiments wake up NRSC-5 compliant, In-band on-channel (IBOC) radio logic to process an Active Radio message to output information associated with the first indication.

Abstract: A digital radio broadcast system includes a processing system that receives first audio content, first program data identifying a first item for the first audio content, second audio content, and second program data identifying a second item for the second audio content such that a start of the first program data is received at the processing system within 0.5 seconds of a start of the first audio content. A digital radio broadcast signal including the audio content and the program data is processed for digital radio broadcast transmission via a transmitter. The processing system stops delivery of the first program data to the transmitter upon receipt of the second program data, the first program data thereby being truncated, and begins delivery of the second program data to the transmitter. A digital radio broadcast receiver can tag content of interest based on a user command registered at the receiver.
