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

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
