Systems and methods for detection of signal quality in digital radio broadcast signals

Systems, methods, and processor readable media are disclosed for detection of signal quality problems and errors in digital radio broadcast signals. First monitoring equipment is located in an over-the-air coverage area of a first radio station. ... Ibiquity Digital Corporation

Method and apparatus for analog and digital audio blend for hd radio receivers

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.. . ... Ibiquity Digital Corporation

Systems and methods for emergency vehicle proximity warnings using digital radio broadcast

Systems and methods are disclosed for communicating an emergency alert message from a digital radio broadcast transmission system of a mobile vehicle to a digital radio broadcast receiver system. A digital radio broadcast signal including first and second data is broadcasted using the digital radio broadcast transmission system to end-user digital radio broadcast receivers. ... Ibiquity Digital Corporation

Systems, methods, and computer readable media for digital radio broadcast receiver memory and power reduction

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. ... Ibiquity Digital Corporation

Method and apparatus for implementing signal quality metrics and antenna diversity switching control

A method for detecting the digital quality of a radio signal includes: receiving a radio signal including an analog modulated portion; digitally sampling an analog modulated portion of the radio signal to produce a plurality of samples; using a ratio between an average magnitude and an rms magnitude of a block of the samples to compute an analog signal quality metric. Receivers that implement the method are also provided.. ... Ibiquity Digital Corporation

Fm analog demodulator compatible with iboc signals

A method includes: receiving an fm radio signal including an analog-modulated portion; digitally sampling an analog-modulated portion of the radio signal to produce a plurality of samples; using a ratio between an average magnitude and an rms magnitude of a block of the samples to compute a signal quality metric; detecting sum and difference components of the baseband multiplex signal content; using the baseband content to produce an output signal; and blending the output signal from stereo to monaural as the signal quality metric falls below a threshold value.. . ...
