Patent number: 9148661Abstract: A method comprises determining a plurality of time intervals Tp and Tn within a variable bit rate (VBR) representation of an image sequence. The time intervals Tp are those in which a number of blocks of information per unit time is greater than a baseline value. The time intervals Tn are those in which a number of blocks of information per unit time is less than the baseline value. A second representation of the image sequence is created in which some blocks of information Bp are removed from the time intervals Tp and interlaced with blocks of information Bn in the time intervals Tn to reduce a variation in a number of blocks of information per unit time between the time intervals Tp and Tn.Type: GrantFiled: June 2, 2014Date of Patent: September 29, 2015Assignee: AT&T Intellectual Property I, L.P.Inventors: Pierre Costa, Ahmad Ansari, John Robert Erickson

Publication number: 20150222872Abstract: A system that incorporates teachings of the present disclosure may include, for example, a process that includes obtaining three-dimensional image content having first and second images. The first and second images include first and second numbers of pixels. The first and second images are arranged according to a shared coordinate system to portray different perspectives of a common scene. A first portion of pixels are removed from the first image based on a filtering of the first image, resulting in a first remaining number of pixels. A second portion of pixels are removed from the second image based on positions of the first portion of pixels in the shared coordinate system, resulting in a second remaining number of pixels. The first remaining portion of pixels is combined with the second remaining portion of pixels to form a transport frame for delivery to a media processor.

Patent number: 8776153Abstract: A system for transporting content to subscriber premises includes a centralized content repository, a subscriber unit, and a network connecting the subscriber unit and repository. The content can be video, image, or other files and the network can include a digital subscriber line (DSL) link. The repository stores higher quality parts of decomposed content files. The subscriber unit locally stores lower quality parts of the content files corresponding to the higher quality parts in the repository. The lower quality parts can be downloaded to the subscriber unit during off-peak hours. During operation, a subscriber selects a locally stored file. In response to the selection, the repository downloads at least one of the higher quality parts corresponding to the selected file to be combined with one of the lower quality parts stored by the subscriber unit for real-time presentation of the content.Type: GrantFiled: April 25, 2001Date of Patent: July 8, 2014Assignee: AT&T Intellectual Property I, LPInventors: Ahmad Ansari, John Robert Erickson, Pierre Costa, Brad Allen Medford

Patent number: 8453183Abstract: A system and method of processing a satellite signal is disclosed. In a particular embodiment, the method includes receiving a satellite signal at a receiver, where the satellite signal includes a Moving Picture Experts Group (MPEG) portion and a radio frequency (RF) portion. The method also includes decoding the satellite signal to produce a digital MPEG transport stream signal that includes the MPEG portion, by removing the RF portion from the satellite signal without substantially altering the MPEG portion. The method also includes transmitting the digital MPEG transport stream signal to a vestigial sideband (VSB) modulator, where the VSB modulator transmodulates the digital MPEG transport stream signal to a VSB signal.Type: GrantFiled: January 23, 2006Date of Patent: May 28, 2013Assignee: AT&T Intellectual Property I, L.P.Inventors: Brad Allen Medford, Ahmad Ansari, Dinesh Nadarajah
