Publication number: 20200154141Abstract: An idea used herein is to use the same function for the dependency of the context and the dependency of the symbolization parameter on previously coded/decoded transform coefficients. Using the same function—with varying function parameter—may even be used with respect to different transform block sizes and/or frequency portions of the transform blocks in case of the transform coefficients being spatially arranged in transform blocks. A further variant of this idea is to use the same function for the dependency of a symbolization parameter on previously coded/decoded transform coefficients for different sizes of the current transform coefficient's transform block, different information component types of the current transform coefficient's transform block and/or different frequency portions the current transform coefficient is located within the transform block.Type: ApplicationFiled: January 17, 2020Publication date: May 14, 2020Inventors: Tung NGUYEN, Heiner KIRCHHOFFER, Detlev MARPE

Patent number: 10644719Abstract: Decomposing a value range of the respective syntax elements into a sequence of n partitions with coding the components of z laying within the respective partitions separately with at least one by VLC coding and with at least one by PIPE or entropy coding is used to greatly increase the compression efficiency at a moderate coding overhead since the coding scheme used may be better adapted to the syntax element statistics. Accordingly, syntax elements are decomposed into a respective number n of source symbols si with i=1 . . . n, the respective number n of source symbols depending on as to which of a sequence of n partitions into which a value range of the respective syntax elements is sub-divided, a value z of the respective syntax elements falls into, so that a sum of values of the respective number of source symbols si yields z, and, if n>1, for all i=1 . . . n?1, the value of si corresponds to a range of the ith partition.Type: GrantFiled: July 11, 2019Date of Patent: May 5, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Detlev Marpe, Tung Nguyen, Heiko Schwarz, Thomas Wiegand

Patent number: 10645388Abstract: A decoder includes an entropy decoder configured to derive a number of bins of the binarizations from the data stream using binary entropy decoding by selecting a context among different contexts and updating probability states associated with the different contexts, dependent on previously decoded portions of the data stream; a desymbolizer configured to debinarize the binarizations of the syntax elements to obtain integer values of the syntax elements; a reconstructor configured to reconstruct the video based on the integer values of the syntax elements using a quantization parameter, wherein the entropy decoder is configured to distinguish between 126 probability states and to initialize the probability states associated with the different contexts according to a linear equation of the quantization parameter, wherein the entropy decoder is configured to, for each of the different contexts, derive a slope and an offset of the linear equation from first and second four bit parts of a respective 8 bit initialType: GrantFiled: June 26, 2019Date of Patent: May 5, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Valeri George, Benjamin Bross, Heiner Kirchhoffer, Detlev Marpe, Tung Nguyen, Matthias Preiss, Mischa Siekmann, Jan Stegemann, Thomas Wiegand

Patent number: 10630988Abstract: An entropy decoder is configured to, for horizontal and vertical components of motion vector differences, derive a truncated unary code from the data stream using context-adaptive binary entropy decoding with exactly one context per bin position of the truncated unary code, which is common for horizontal and vertical components of the motion vector differences, and an Exp-Golomb code using a constant equi-probability bypass mode to obtain the binarizations of the motion vector differences. A desymbolizer is configured to debinarize the binarizations of the motion vector difference syntax elements to obtain integer values of the horizontal and vertical components of the motion vector differences. A reconstructor is configured to reconstruct a video based on the integer values of the horizontal and vertical components of the motion vector differences.Type: GrantFiled: June 27, 2019Date of Patent: April 21, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Valeri George, Benjamin Bross, Heiner Kirchhoffer, Detlev Marpe, Tung Nguyen, Matthias Preiss, Mischa Siekmann, Jan Stegemann, Thomas Wiegand

Publication number: 20200092366Abstract: The concepts and technologies disclosed herein are directed to peer packet transport. According to one aspect disclosed herein, a scheduler system can receive a content delivery request to transport a data payload of content to a destination location by a specific time. A prediction system can identify a data path that meets connectivity between an origin location and the destination location with delivery of the data payload of content by the specific time. The prediction system can inform the scheduler system of the data path that meets connectivity between the origin location and the destination location with delivery of the data payload of content by the specific time. The scheduler system can coordinate, among a plurality of data courier devices, transport, along the data path, of the data payload of the content from the origin location to the destination location by the specific time.Type: ApplicationFiled: September 18, 2018Publication date: March 19, 2020Applicant: AT&T Intellectual Property I, L.P.Inventors: Jeremy T.

Patent number: 10587884Abstract: A higher coding efficiency for coding a significance map indicating positions of significant transform coefficients within a transform coefficient block is achieved by the scan order by which the sequentially extracted syntax elements indicating, for associated positions within the transform coefficient block, as to whether at the respective position a significant or insignificant transform coefficient is situated, are sequentially associated to the positions of the transform coefficient block, among the positions of the transform coefficient block depends on the positions of the significant transform coefficients indicated by previously associated syntax elements. Alternatively, the first-type elements may be context-adaptively entropy decoded using contexts which are individually selected for each of the syntax elements dependent on a number of significant transform coefficients in a neighborhood of the respective syntax element, indicated as being significant by any of the preceding syntax elements.Type: GrantFiled: May 14, 2019Date of Patent: March 10, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Heiner Kirchhoffer, Heiko Schwarz, Tung Nguyen, Detlev Marpe, Thomas Wiegand
