Abstract: Travel-related-information messages (TRIMS) are received from one or more information sources, and information included in the messages is separated into a first (e.g. TPEG™) or second (e.g. TPEG+) group. A broadcast area to which the information included in the TRIMs is to be broadcast is determined. A further determination indicates that a subset of information assigned to the first group is to be reassigned to the second group. The subset of information is reassigned from the first group to the second group based on parameters associated with the broadcast area. The information included in the first group and the second group is delivered to one or more processing modules that generate a first TRIM reporting message using information included in the first group and a second TRIM reporting message using information included in the second group.

Abstract: A method includes determining, at a device, that transmission data indicates that first data was transmitted via a digital radio channel. The method also includes determining, at the device, that reception data indicates that second data was received via the digital radio channel. The first data has a first size that is less than a second size of the second data. The method also includes determining, at the device, whether an error occurred in transmission of the first data based on determining whether each of a plurality of portions of the first data is included at least once in the second data. Other aspects are also disclosed.

Abstract: A method for processing a digital audio broadcast signal in a radio receiver, includes: receiving a hybrid broadcast signal; demodulating the hybrid broadcast signal to produce an analog audio stream and a digital audio stream; and using a normalized cross-correlation of envelopes of the analog audio stream and the digital audio stream to measure a time offset between the analog audio stream and the digital audio stream. The time offset can be used to align the analog audio stream and the digital audio stream for subsequent blending of an output of the radio receiver from the analog audio stream to the digital audio stream or from the digital audio stream to the analog audio stream.

Abstract: A method of processing a digital radio broadcast signal in a digital radio receiver includes: receiving baseband signal samples at a first sample rate; adjusting the sample rate of the baseband signals based on a difference between a receiver clock and a transmitter clock to produce adjusted baseband signal samples at a second sample rate; filtering the adjusted baseband signal samples to separate a digital component of the samples and an analog component of the samples, wherein the digital component and the analog component are synchronous; and separately demodulating the digital component and the analog component to produce a digital output signal and an analog output signal. A receiver that uses the method is also provided.

Abstract: A method and apparatus are provided for blending analog and digital portions of a composite digital radio broadcast signal by processing compressed audio packets to compute corresponding digital audio quality indicator values, storing the compressed audio packets in an audio blend buffer, processing audio information from each compressed audio packet stored in the audio blend buffer with an audio decoder to generate decompressed digital audio signal samples, and using the digital audio quality indicator values to guide a blending process for combining analog audio signal samples with the digital audio signal samples to produce an audio output by preventing unnecessary blending back and forth between analog and digital if the digital audio quality indicator values indicate that the compressed audio packets are degraded or impaired.

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: Systems and methods are described for rendering content at a digital radio broadcast receiver system. A digital radio broadcast signal comprises data for rendering content at the digital radio broadcast receiver. The digital radio broadcast signal is processed to determine whether the data from the digital radio broadcast transmission contains a data error. A portion of the data containing the data error is identified. A download request is transmitted to a computing system, where the download request requests duplicate data for the portion of the data containing the data error. The duplicate data is received at the digital radio broadcast receiver for the portion of the data containing the error via other wireless communication other than the digital radio broadcast. The duplicate data is processed to provide an uninterrupted rendering of the content.
