20090161196 | SYSTEM AND METHOD FOR SPECKLE REDUCTION FROM A COHERENT LIGHT SOURCE IN A PROJECTION DEVICE - Embodiments of the present invention are directed to a system and method for reducing speckle phenomenon caused by a coherent light source. Particular embodiments of the present invention are directed to a system and method for temporally varying the interference pattern generated by a coherent light source to homogenize the speckle pattern so that the speckle phenomenon is less observable. In accordance with an exemplary embodiment, an oscillating refractive element may be disposed within an optical system to create a temporally variable phase shift in the lights rays emanating from a coherent light source to eliminate static interference patterns on a light receiving element, reducing the speckle phenomenon. | 06-25-2009 |
20090174867 | SYSTEM AND METHOD FOR REDUCING IMAGE ARTIFACTS IN A PROJECTION DEVICE USING A SCROLLING REFRACTIVE ELEMENT - A system and method for reducing speckle and smearing phenomena caused by a coherent light source. The light beam from the coherent light source is preferably refracted by a rotating refractive element. The refracted beam is focused and projected through a light valve by a plurality of optical components. The rotation of the refractive element causes the beam to scroll across the surface of a light receiving element, which reduces the smearing effect. The rotation of the refractive element also causes the propagation path of the beam to vary, causing rays of the light beam to undergo relative phase shift, varying the interference pattern on the light receiving element, resulting in a reduction in the appearance of the speckle phenomenon. | 07-09-2009 |

20090080644 | SIGNAL PROCESSING - The present invention relates to detection of echo in telecommunications networks. The invention provides a method of echo detection comprising the steps of: generating a series of inbound vectors for an inbound signal; generating a series of outbound vectors for an outbound signal; repeating a predetermined number of comparison steps comprising the sub-steps of selecting an outbound vector from the outbound vectors; selecting an inbound vector from the inbound vectors; comparing said outbound vector with said inbound vector and with successive inbound vectors to generate a plurality of similarity metrics; and determining a relative position of the compared outbound vector having maximum correlation with said inbound vector; and counting the number of times each relative position is determined to be the position of maximum correlation. | 03-26-2009 |

20130083203 | System and Method for Diagnostic Modeling of Audio and Video Quality of Service - Systems and methods are described for determining a set of three quality metrics for audio and/or video signals transmitted through a packet network. The set of three metrics provide more insight into which factors are affecting the quality of the received signal as perceived by the end-user. These three quality metrics measure reductions in quality due to lossy media transmission, packet loss concealment from packet loss and/or packet/frame jitter, and long periods of silence and/or frozen video. Because each metric quantifies a different aspect of transmitted quality, a deficiency in the transmitted signal can be identified by reference to the set. | 04-04-2013 |

20090279777 | METHOD AND APPARATUS FOR ALIGNING SIGNALS - This invention relates to alignment of signals, particularly for use in a quality assessment system. The invention provides a method and apparatus for aligning a first signal comprising a sequence of frames with a second signal comprising a sequence of frames, the method comprising the steps of: determining a similarity measure between each of a plurality of frames of the first signal and each of a plurality of frames of the second signal; assigning a matching value to each frame of the first signal wherein the matching value indicates a relative position of a matching frame in the second signal, by repeating the sub-steps of: generating a relative delay histogram the histogram comprising a set of values corresponding to each of a set of relative delays by: selecting a subset of frames of the first signal and for each frame of said subset identifying the frame of the second signal having the greatest similarity with said frame; determining the relative delay between the identified frame of the second signal and said frame of the first signal; and incrementing the value of the histogram corresponding to said relative delay; identifying one or more peaks in the relative delay histogram; and assigning the matching value to each frame contributing to a peak in dependence upon said identified peaks. | 11-12-2009 |
