  • Publication number: 20170111737
    Abstract: An audio processing circuit comprises an analyzer circuit that includes a plurality of energy detector units, and an equalizer circuit that includes a plurality of equalization filters. The equalizer circuit is coupled with the analyzer circuit. The analyzer circuit is configured to receive an audio signal, obtain sub-bands of the audio signal using the energy detector units, measure energy of each sub-band, compare the energy of each sub-band to a threshold energy value and, based on the comparison, determine parameters for an equalization filter for processing the sub-band. The equalizer circuit is configured to receive the audio signal concurrently with reception of the audio signal by the analyzer circuit, obtain the sub-bands using the equalization filters, receive the parameters for the equalization filters from the analyzer circuit, equalize each sub-band by applying the parameters corresponding to the sub-band, and generate an output audio signal that includes the equalized sub-bands.

  • Patent number: 8995242
    Abstract: A system and method for adjusting the radial tilt, tangential tilt, or a combination of radial and tangential tilt of an optical detection unit in an optical disc reading system can include applying different weighting factors to different signal components depending on which detection area detects the component, measuring a value of a signal characteristic, such as signal-to-noise ratio, of two signals with different sets of weighting factors, and determining an adjustment factor to the radial tilt as a function of the of the measured signal characteristic values.

  • Patent number: 8879372
    Abstract: A differential phase detector for an optical storage system is set forth. The differential phase detector includes a photodetector circuit arranged to detect light deviations associated with radial errors in the optical storage system. A non-linear equalizer is in communication with the photodetector circuit. The output of the non-linear equalizer is in communication with signal processing circuitry. The signal processing circuitry uses the equalized signals to generate one or more radial error signals.

  • Publication number: 20140115106
    Abstract: A method and apparatus is provided for delivering a content file to a client over a packet-switched network. The method begins by determining a suitable throughput required to deliver the content file to the client. Next, the throughput available in a peer-to-peer network for delivering the content file to the client is determined. The required throughput is compared to the available throughput. If the available throughput is less than the required throughput, the available throughput is supplemented with additional throughput. The content is then delivered to the client over the packet-switched network using the available throughput of the peer-to-peer network and the additional throughput.

  • Patent number: 8693300
    Abstract: A system includes a position detection module configured to detect at least a first position indicator and a second position indicator corresponding to a label side of an optical disc. A write clock adjustment module is configured to determine a number of cycles of a write clock that occur between the first position indicator and the second position indicator, determine a difference between the number of cycles of the write clock and a desired number of cycles of the write clock, and adjust a frequency of the write clock based on the difference.

  • Patent number: 8089836
    Abstract: A phase detector comprises a first slicing circuit that generates a first digital signal corresponding to a logic state of a first generally continuous signal. A second slicing circuit generates a second digital signal corresponding to a logical state of a second generally continuous signal. Phase detector logic compares triggering edges of the first and second digital signals to generate a phase difference signal having a pulse width corresponding to a phase difference between the first and second generally continuous signals. Aberration compensation circuitry is in communication with the phase detector logic to ensure generation of the phase difference signal in the presence of signal aberrations occurring at the triggering edges of the first and second digital signals.
