Patent number: 8958481Abstract: Methods and systems are provided for encoding and decoding a video stream. Each picture in a video stream can be divided into slices, each of which contains a contiguous row of macroblocks. All the blocks corresponding to a single video component within each slice can then be used as the basis for encoding the picture. By decomposing each picture into slices, the video stream can be efficiently converted for displays of varying size and/or quality. The encoded bitstream can include a slice table to allow direct access to each slice without reading the entire bitstream. Each slice can also be processed independently, allowing for parallelized encoding and/or decoding.Type: GrantFiled: November 8, 2013Date of Patent: February 17, 2015Assignee: Apple Inc.Inventors: Ken Kengkuan Lin, Peter Hungye Chou, Mitchell Howard Oslick, Gregory Kent Wallace, Shahriar M.

Patent number: 8437392Abstract: Systems and methods for editing and selectively encoding video. In general, in one implementation, the method includes generating video segments from portions of one or more video sources, at least one video source being encoded to have interframe dependencies; generating a video sequence from the video segments; scanning the generated video sequence to identify invalid interframe dependencies; and selectively reencoding portions of the generated video sequence to generate an output video sequence having valid interframe dependencies. The method may further comprise generating the output video sequence without reencoding valid portions of the video sequence. Valid portions of the video sequence may comprise portions lacking invalid interframe dependencies or buffer violations.Type: GrantFiled: April 15, 2005Date of Patent: May 7, 2013Assignee: Apple Inc.Inventors: Peter Hungye Chou, Gregory Kent Wallace, Sachin Agarwal, Jian Lu

Patent number: 8208789Abstract: Video program authoring systems and methods in a processor-based system removes an author from consideration of low-level configuration functions during authoring. The authoring systems and methods provide an authoring engine having an interactive graphical authoring interface, a data management engine, an emulator, a compiler, a multiplexer and a simulator. Using summary authoring data, the compiler builds a skeleton-faun layout structure comprising abstracted components that include movie chapters, menu buttons and command segements. The compiler then resolves abstracted connections between combinations of the abstracted components to produce a video program. Instructions associated with the command segments and a configuration of the command segments within a video program video space and domain structure are abstracted.Type: GrantFiled: September 27, 2006Date of Patent: June 26, 2012Assignee: Apple Inc.Inventors: Rainer Brodersen, Gregory Kent Wallace

Patent number: 8180194Abstract: A storage medium is encoded with a video program created using authoring systems and methods. The processor-based authoring system removes an author from consideration of low-level configuration functions during authoring. The authoring system includes an authoring engine having an interactive graphical authoring interface, a data management engine, an emulator, a compiler, a multiplexer and a simulator. The authoring methods include the use of summary authoring data, a compiler that builds a skeleton-form layout structure comprising abstracted components that include movie chapters, menu buttons and command segements. The compiler resolves abstracted connections between combinations of the abstracted components to produce a video program. Instructions associated with the command segments and a configuration of the command segments within a video program video space and domain structure are abstracted the functional during authoring.Type: GrantFiled: February 27, 2007Date of Patent: May 15, 2012Assignee: APPLE Inc.Inventors: Rainer Brodersen, Gregory Kent Wallace

Patent number: 7873225Abstract: Embodiments of the present invention provide a coding system that codes data according to a pair of coding chains. A first coding chain generates coded video data that can be decoded by itself to represent a source video sequence of a small size, such as a size sufficient to support the real time playback and display features of a video editing application. The second coding chain generates coded video data representing supplementary data, which when decoded in conjunction with the coded video data of the first coding chain, yields the source video sequence for full-size display. The output of the first coding chain may be stored in memory in a file structure that can be accessed independently of the second chain's output and, therefore, it facilitates real time decoding and playback.Type: GrantFiled: March 6, 2009Date of Patent: January 18, 2011Assignee: Apple Inc.Inventors: Gregory Kent Wallace, Haitao Guo, Mitchell Howard Oslick

Patent number: 7200836Abstract: A DVD authoring system in a processor-based system removes an author from consideration of the DVD Specification during authoring. According to a preferred embodiment, the authoring system provides an authoring engine having an interactive graphical authoring interface, a data management engine, an emulator, a compiler, a multiplexer and a simulator. Using summary authoring data, the compiler builds a skeleton-form PGC layout structure comprising control PGC abstractions and router PGC abstractions. The compiler then resolves the PGC abstractions according to source-target connections. During playback on a DVD player, the PGC abstractions form elements in a connection-switching abstraction superstructure. Accordingly, in response to DVD-consumer and other control events, a source PGC preferably determines target PGC information and then transfers control, via virtual connections through necessary router PGC abstractions, to a target PGC abstraction.Type: GrantFiled: August 5, 2002Date of Patent: April 3, 2007Assignee: Apple Computer, Inc.Inventors: Rainer Brodersen, Gregory Kent Wallace
