20080218630 | Content-Dependent Scan Rate Converter with Adaptive Noise Reduction - A content-dependent scan rate converter with adaptive noise reduction that provides a highly integrated, implementation efficient de-interlacer. By identifying and using redundant information from the image (motion values and edge directions), this scan rate converter is able to perform the tasks of film-mode detection, motion-adaptive scan rate conversion, and content-dependent video noise reduction. Adaptive video noise reduction is incorporated in the process where temporal noise reduction is performed on the still parts of the image, thus preserving high detail spatial information, and data-adaptive spatial noise reduction is performed on the moving parts of the image. A low-pass filter is used in flat fields to smooth out Gaussian noise and a direction-dependent median filter is used in the presence of impulsive noise or an edge. Therefore, the selected spatial filter is optimized for the particular pixel that is being processed to maintain crisp edges. | 09-11-2008 |

20100074623 | THREE-WAY HANDSHAKE (3WHS) OPTICAL NETWORK SIGNALING PROTOCOL - A method for optical network signaling processing of a signal from a first node to an end node through intermediate nodes is presented. The method comprises determining, in a first pass from the first node to the end node, available wavelengths and wavelength conversion at each node, the end node optimizing wavelengths using the available wavelengths and wavelength conversions, at each node, dropping a cross-connect command, in a second pass from the end node to the first node, choosing wavelengths for connection based on the optimizing step, in a third pass from the first node to the end node, receiving at each node a signal message and releasing unused cross-connect commands, the end node identifying the chosen wavelengths and releasing the unused resources, and transmitting the signal on the chosen wavelengths. Restoration paths can also be determined. Optimizing can include selecting and marking one or more backup wavelengths. | 03-25-2010 |
20110135299 | DIFFERENTIAL EYE DIAGRAMS - Changes in a signal are detected. The signal is repeatedly sampled in a synchronous manner during a predetermined interval to generate a captured eye diagram. At least one of a positive differential eye diagram or a negative differential eye diagram is generated from the captured eye diagram and a baseline eye diagram. The at least one positive or negative differential eye diagram is analyzed to determine whether a change in signal conditions is present. | 06-09-2011 |
20120106966 | TRANSPONDER POOL SIZING IN HIGHLY DYNAMIC TRANSLUCENT WDM OPTICAL NETWORKS - A system and method for sizing transponder pools in a dynamic wavelength division multiplexing optical network having selected nodes designated to have a shared transponder pool is presented. The method comprises performing network simulations, generating transponder pool histograms (for each node having a transponder pool) based on the network simulations, performing statistical analysis using the transponder pool histograms to determine probability distribution and distribution parameters for each node and to calculate the horizontal axis location that has a specified distribution tail area, sizing the transponder pools according to the horizontal axis location that has the desired distribution tail area, executing network call blocking simulations to calculate call blocking probabilities, determining whether the call blocking probabilities meet blocking requirements, when the blocking requirements are met, using the sized transponder pools, and when the blocking requirements are not met, adjusting the distribution tail area and repeating sizing, executing and determining steps. | 05-03-2012 |

20130163983 | Signaling Protocol for Multi-Domain Optical Networks - A three-way handshake method for optical messaging in a multi-domain optical network that includes a first pass from a source domain to a destination domain through intermediate domains on candidate working paths, collecting information identifying available routing resources for each working path, calculating a working path metric and storing each of the metrics at the respective border node, determining a path key of the topology of each domain working path and using the path key to identify the path outside its domain and determining the best working paths and border nodes to use. A second pass using the path keys for identifying the working path in each domain and reserving the identified routing resources and selecting which routing resources to use. A third pass identifying the selected routing resources and establishing an optical signaling message path between the source node and the destination node. | 06-27-2013 |
