Patent number: 8621532Abstract: Video-coded information is transmitted over a network at a priority level that is determined based on feedback from the network. In an embodiment, the feedback comprises a response to a request for information on whether the network currently has the available capacity to transmit additional high priority traffic. In an embodiment, a candidate base layer frame is transmitted over a network as a base layer frame if permission to send high priority data was granted and is transmitted over the network as an enhancement layer frame if permission to send high priority data was denied. In a further embodiment, the candidate base layer frame is deleted if permission to send high priority data was denied.Type: GrantFiled: May 23, 2006Date of Patent: December 31, 2013Assignee: AT&T Intellectual Property II, L.P.Inventors: Baldine-Brunel Paul, Glenn L. Cash, M. Reha Civanlar, Barin Geoffry Haskell, Paul G. Howard, Atul Puri, Robert Lewis Schmidt

Patent number: 8489954Abstract: Methods and apparatuses to model the relation between the delay samples and congestion losses and to protect media flows against congestion losses are disclosed. In one embodiment, the method comprises measuring congestion by delay samples, and performing a dynamic FEC algorithm that uses convex hull clustering for loss-event classification, including determining an FEC rate according to the loss-event classification. In another embodiment, the method comprises measuring congestion by delay samples, modeling loss events associated with the delay samples by grouping loss events as unions of convex hulls to identify a period of potentially increased congestion, dynamically changing the FEC rate based on the modeling, and applying FEC protection to the media flow during the period based on the FEC rate.Type: GrantFiled: July 23, 2009Date of Patent: July 16, 2013Assignee: NTT DoCoMo, Inc.Inventors: Hulya Seferoglu, Ulas C. Kozat, M. Reha Civanlar, James Kempf

Patent number: 5313567Abstract: An imaging system apparatus and operating method thereof utilize a volumetric resampling technique with interpolation to determine sample point values on user-defined paths traced through a volumetric image comprising a group of predefined data values, which are themselves samples of a continuous volumetric object. Data values to be displayed are determined from the sample point values using user-selected interpolation and visualization operating modes.Type: GrantFiled: June 13, 1991Date of Patent: May 17, 1994Assignee: AT&T Bell LaboratoriesInventors: M.

Patent number: 5187660Abstract: A facility is provided for greatly enhancing the rate at which volumetric data is processed by display on a two-dimensional display. Specifically, the volumetric data is first divided into a predetermined number of sub-blocks, in which a predetermined voxel in each sub-block is then transformed into an associated picture element. The sub-blocks and their associated pixels are then supplied to respective processors forming an array of processors. Each processor then completes the transformation of its sub-block as a function of the coordinates of the associated picture element and respective incremental vectors.Type: GrantFiled: December 1, 1989Date of Patent: February 16, 1993Assignee: AT&T Bell LaboratoriesInventors: M.
