Patent number: 10694198Abstract: The handling of scalable data streams by network entities is rendered less complex by, in the data stream, accompanying packets which actually carry data by packets of a different packet type which have a scalability axes descriptor defining the number of scalability axes and a semantic meaning thereof. In another aspect, the handling of scalable data streams by network entities is rendered more efficient by conveying level and/or profile descriptors using packets other than the data carrying packets, with profile and/or level descriptors being divided up into a first set explicitly signaling the definition of the available coding option set and/or available syntax element value range for a respective operation point, and a second set of profile and/or level descriptors which signal the definition of the available coding option set and/or available syntax element value range for their respective operation points by reference another profile and/or level descriptor.Type: GrantFiled: July 2, 2018Date of Patent: June 23, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Thomas Schierl, Valeri George, Anastasia Henkel, Detlev Marpe, Karsten Grüneberg, Robert Skupin

Patent number: 10694165Abstract: The usual coding order according to which the reference view is coded prior to the dependent view, and within each view, a depth map is coded subsequent to the respective picture, may be maintained and does lead to a sacrifice of efficiency in performing inter-view redundancy removal by, for example, predicting motion data of the current picture of the dependent view from motion data of the current picture of the reference view. Rather, a depth map estimate of the current picture of the dependent view is obtained by warping the depth map of the current picture of the reference view into the dependent view, thereby enabling various methods of inter-view redundancy reduction more efficiently by bridging the gap between the views.Type: GrantFiled: May 9, 2014Date of Patent: June 23, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Heiko Schwarz, Thomas Wiegand

Patent number: 10694218Abstract: A better compromise between encoding complexity and achievable rate distortion ratio, and/or to achieve a better rate distortion ratio is achieved by using multitree sub-divisioning not only in order to subdivide a continuous area, namely the sample array, into leaf regions, but using the intermediate regions also to share coding parameters among the corresponding collocated leaf blocks. By this measure, coding procedures performed in tiles—leaf regions—locally, may be associated with coding parameters individually without having to, however, explicitly transmit the whole coding parameters for each leaf region separately. Rather, similarities may effectively exploited by using the multitree subdivision.Type: GrantFiled: January 28, 2019Date of Patent: June 23, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Philipp Helle, Detlev Marpe, Simon Oudin, Thomas Wiegand

Patent number: 10687059Abstract: A subblock-based coding of transform coefficient blocks of the enhancement layer is rendered more efficient. To this end, the subblock subdivision of the respective transform coefficient block is controlled on the basis of the base layer residual signal or the base layer signal. In particular, by exploiting the respective base layer hint, the subblocks may be made longer along a spatial frequency axis transverse to edge extensions observable from the base layer residual signal or the base layer signal.Type: GrantFiled: September 25, 2018Date of Patent: June 16, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Tobias Hinz, Haricharan Lakshman, Jan Stegemann, Philipp Helle, Mischa Siekmann, Karsten Suehring, Detlev Marpe, Heiko Schwarz, Christian Bartnik, Ali Atef Ibrahim Khairat Abdelhamid, Heiner Kirchhoffer, Thomas Wiegand

Patent number: 10687042Abstract: An apparatus for determining a measure for a distortion change of a first view synthesized from a second view, caused by a modification of a depth map of the second view from a first state to a second state, is configured starting from a current synthesis state of the first view corresponding to a synthesis from the second view having the depth map modified to the second state in an already processed portion of the depth map and having the depth map unmodified at the first state in a yet to be processed portion of the depth map—to compute a possible successor synthesis state corresponding to a synthesis of the first view from the second view having the depth map modified to the second state in an already processed portion plus a currently processed portion and having the depth map unmodified at the first state in the yet to be processed portion without the currently processed portion; and to determine a distortion change of a distortion of the current synthesis state of the first view relative to an undistortType: GrantFiled: October 18, 2019Date of Patent: June 16, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Gerhard Tech, Karsten Mueller, Thomas Wiegand

Patent number: 10681348Abstract: The coding efficiency of scalable video coding is increased by substituting missing spatial intra prediction parameter candidates in a spatial neighborhood of a current block of the enhancement layer by use of intra prediction parameters of a co-located block of the base layer signal. By this measure, the coding efficiency for coding the spatial intra prediction parameters is increased due to the improved prediction quality of the set of intra prediction parameters of the enhancement layer, or, more precisely stated, the increased likelihood, that appropriate predictors for the intra prediction parameters for an intra predicted block of the enhancement layer are available thereby increasing the likelihood that the signaling of the intra prediction parameter of the respective enhancement layer block may be performed, on average, with less bits.Type: GrantFiled: November 5, 2018Date of Patent: June 9, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Tobias Hinz, Haricharan Lakshman, Jan Stegemann, Philipp Helle, Mischa Siekmann, Karsten Suehring, Detlev Marpe, Heiko Schwarz, Christian Bartnik, Ali Atef Ibrahim Khairat Abdelhamid, Heiner Kirchhoffer, Thomas Wiegand

Patent number: 10672028Abstract: A favorable merging or grouping of simply connected regions into which the array of information samples is sub-divided, is coded with a reduced amount of data. To this end, a predetermined relative locational relationship is defined enabling an identifying, for a predetermined simply connected region, of simply connected regions within the plurality of simply connected regions which have the predetermined relative locational relationship to the predetermined simply connected region. Namely, if the number is zero, a merge indicator for the predetermined simply connected region may be absent within the data stream. In other embodiments, spatial sub-division is performed depending on a first subset of syntax elements, followed by combining spatially neighboring simply connected regions depending on a second subset of syntax elements, to obtain an intermediate sub-division.Type: GrantFiled: February 5, 2019Date of Patent: June 2, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Philipp Helle, Simon Oudin, Martin Winken, Detlev Marpe, Thomas Wiegand

Patent number: 10674134Abstract: A higher compression rate or better rate/distortion ratio may be achieved by adopting or predicting second coding parameters used for encoding a second view of the multi-view signal from first coding parameters used in encoding a first view of the multi-view signal. In other words, redundancies between views of a multi-view signal are not restricted to the views themselves, such as the video information thereof, but that the coding parameters in encoding these views in parallel show similarities, which may be exploited in order to further improve the coding rate.Type: GrantFiled: September 21, 2018Date of Patent: June 2, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Thomas Wiegand, Detlev Marpe, Karsten Mueller, Philipp Merkle, Gerhard Tech, Hunn Rhee, Heiko Schwarz

Patent number: 10674164Abstract: Parallel processing concepts such as wavefront parallel processing, are realized with a reduced end-to-end delay by giving up the usual slice concept according to which slices are either coded/decoded completely independent from areas of the picture outside of the respective slice, or at least independent from areas outside the respective slice as far as the entropy coding is concerned, namely in favor of slices of different modes, namely ones called dependent slices which allow for interdependencies across slice boundaries, and others which do not, called normal slices, for example. Combined with the aspect or not, WPP processing concept is made more efficiently by using the slices' start syntax portions to locate WPP entry points.Type: GrantFiled: October 5, 2018Date of Patent: June 2, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Thomas Schierl, Valeri George, Anastasia Henkel, Detlev Marpe, Karsten Grüneberg, Robert Skupin

Patent number: 10659754Abstract: A gain in multi-view coding is achieved as follows: the residual signal involved with coding a dependent view of the multi-view signal is predicted from a reference residual signal of the current picture of the reference view using block-granular disparity-compensated prediction, i.e. using disparity compensated prediction with a disparity defined at, and varying with, block granularity so that each block of the current picture of the dependent view has its own disparity displacement such as its own disparity vector, associated therewith. In other words, a remaining similarity between the residual signal involved with predictively coding the reference view is used in order to predict the residual signal involved with predictively coding the dependent view.Type: GrantFiled: May 15, 2014Date of Patent: May 19, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Heiko Schwarz, Thomas Wiegand, Martin Winken

Patent number: 10659776Abstract: A more efficient way of addressing different bit-depths, or different bit-depths and chroma sampling format requirements is achieved by using a low bit-depth and/or low-chroma resolution representation for providing a respective base layer data stream representing this low bit-depth and/or low-chroma resolution representation as well as for providing a higher bit-depth and/or higher chroma resolution representation so that a respective prediction residual may be encoded in order to obtain a higher bit-depth and/or higher chroma resolution representation. By this measure, an encoder is enabled to store a base-quality representation of a picture or a video sequence, which can be decoded by any legacy decoder or video decoder, together with an enhancement signal for higher bit-depth and/or reduced chroma sub-sampling, which may be ignored by legacy decoders or video decoders.Type: GrantFiled: November 14, 2018Date of Patent: May 19, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Detlev Marpe, Martin Winken, Heiko Schwarz, Thomas Wiegand

Patent number: 10659798Abstract: The entropy coding of a current part of a predetermined entropy slice is based on, not only, the respective probability estimations of the predetermined entropy slice as adapted using the previously coded part of the predetermined entropy slice, but also probability estimations as used in the entropy coding of a spatially neighboring, in entropy slice order preceding entropy slice at a neighboring part thereof. Thereby, the probability estimations used in entropy coding are adapted to the actual symbol statistics more closely, thereby lowering the coding efficiency decrease normally caused by lower-delay concepts. Temporal interrelationships are exploited additionally or alternatively.Type: GrantFiled: August 23, 2018Date of Patent: May 19, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Valeri George, Anastasia Henkel, Heiner Kirchhoffer, Detlev Marpe, Thomas Schierl

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
