  • Publication number: 20130027513
    Abstract: A system for adjusting the perceived depth of 3D content in response to a viewer input control signal. The system comprises: 1) a content source providing an input left stereoscopic image and an input right stereoscopic image; 2) a disparity estimator to receive the input left and right stereoscopic images, detect disparities between the input left and right stereoscopic images, and generate a disparities array; and 3) processing circuitry to fill in occlusion areas associated with the disparities array and apply a scale factor to the detected disparities to thereby generate a scaled disparities array. The system further comprises a warping engine to receive the scaled disparities array and generate an output left stereoscopic image and an output right stereoscopic image. The output left and right stereoscopic images have a different perceived depth than the input left and right stereoscopic images.

  • Publication number: 20120269305
    Abstract: A receive channel offset correction scheme utilizes “eye edge” samplers and demultiplexers already present and essential for operation of the CDR algorithm, and adds only simple word-rate logic, with no new analog circuitry. The result is the ability to precisely determine the offset polarity as well as to get an approximate immediate measure of the offset magnitude. The offset detected includes all of the analog circuitry in the channel, including the samplers themselves.

  • Publication number: 20120170691
    Abstract: Interference cancellation for wideband and narrowband communications systems is provided without apriori knowledge of statistical information about an interfering signal. In one embodiment a demodulator circuit can operate in an environment where a “no lock” situation would normally occur to remove the interference and acquire signals in low signal-to-noise ratio (SNR) conditions and high signal-to-interference ration (SIR) conditions. In other embodiments, performance is improved by introducing statistics of the interfering signal, and these statistics regarding the communications channel and interference properties (i.e., characteristics of the interfering signal) can be adaptive or “learned” in other embodiments.
