Patent number: 10694183Abstract: Scalable video coding is rendered more efficient by deriving/selecting a subblock subdivision to be used for enhancement layer prediction, among a set of possible subblock subdivisions of an enhancement layer block by evaluating the spatial variation of the base layer coding parameters over the base layer signal. By this measure, less of the signalization overhead has to be spent on signaling this subblock subdivision within the enhancement layer data stream, if any. The subblock subdivision thus selected may be used in predictively coding/decoding the enhancement layer signal.Type: GrantFiled: September 26, 2018Date of Patent: June 23, 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: 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: 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

Publication number: 20190158826Abstract: The coding efficiency of a multi-component picture or video coding concept is improved by reconstructing a third component signal relating to a third component of the multi-component video using inter-component prediction from both a reconstructed first component signal and a reconstructed second component signal.Type: ApplicationFiled: January 25, 2019Publication date: May 23, 2019Inventors: Tung NGUYEN, Ali Atef Ibrahim KHAIRAT ABDELHAMID, Detlev MARPE

Publication number: 20190158861Abstract: Reconstructing a second component signal relating to a second component of a multi-component picture from a spatially corresponding portion of a reconstructed first component signal and a correction signal derived from a data stream for the second component promises increased coding efficiency over a broader range of multi-component picture content. By including the spatially corresponding portion of the reconstructed first component signal into the reconstruction of the second component signal, any remaining inter-component redundancies/correlations present such as still present despite a possibly a priori performed component space transformation, or present because of having been introduced by such a priori performed component space transformation, for example, may readily be removed by way of the inter-component redundancy/correlation reduction of the second component signal.Type: ApplicationFiled: January 24, 2019Publication date: May 23, 2019Inventors: Tung NGUYEN, Ali Atef Ibrahim KHAIRAT ABDELHAMID, Detlev MARPE
