Publication number: 20230283792Abstract: 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: February 15, 2023Publication date: September 7, 2023Applicant: GE VIDEO COMPRESSION, LLCInventors: Tung NGUYEN, Ali Atef Ibrahim KHAIRAT ABDELHAMID, Detlev MARPE

Publication number: 20230269398Abstract: 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: March 23, 2023Publication date: August 24, 2023Applicant: GE Video Compression, LLCInventors: Tung NGUYEN, Heiner KIRCHHOFFER, Detlev MARPE

Patent number: 11706413Abstract: A picture in a data stream is subdivided into different size transform blocks. For a transform block, a transformation is selected by checking whether the block's size exceeds a threshold. If it does, a default technique is used to select the transformation. If it does not, a transformation is used from a list of transformations as identified by an index, the list including an identity transformation and non-identity transformations. A coefficients block in the data stream is decoded, and if the selected transformation is the identity transformation, then the coefficients block is used as a residual sample array, and if the selected transformation is not the identity transformation, the coefficients block is subjected to an inverse transformation corresponding to the selected transformation to obtain a residual sample array used to correct a prediction for the transform block.Type: GrantFiled: June 29, 2021Date of Patent: July 18, 2023Assignee: Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Benjamin Bross, Phan Hoang Tung Nguyen, Paul Keydel, Heiko Schwarz, Detlev Marpe, Thomas Wiegand, Christian Helmrich

Publication number: 20230188718Abstract: A video encoder is configured to entropy encode an absolute value of a quantization level of a current transform coefficient at position (xC, yC), wherein the absolute value is encoded using context adaptive binary arithmetic encoding of bins of a first binarization. The video coder is further configured, for the current transform coefficient, to encode a bin of the first binarization by using a context which is determined based on a sum of minimum absolute values of transform coefficient quantization levels, based on encoded bins of the first binarization, at one or more transform coefficient positions among (xC+1, yC), (xC+2, yC), (xC+1, yC+1), (xC, yC+1), and (xC, yC+2).Type: ApplicationFiled: February 1, 2023Publication date: June 15, 2023Inventors: Paul HAASE, Christian RUDAT, Heiner KIRCHHOFFER, Phan Hoang Tung NGUYEN, Mischa SIEKMANN, Heiko SCHWARZ, Detlev MARPE, Thomas WIEGAND

Publication number: 20230188719Abstract: 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: ApplicationFiled: November 7, 2022Publication date: June 15, 2023Inventors: Valeri GEORGE, Benjamin BROSS, Heiner KIRCHHODDER, Detlev MARPE, Tung NGUYEN, Matthias PRIESS, Mischa SIEKMANN, Jan STEGEMANN, Thomas WIEGAND

Publication number: 20230085799Abstract: A self-balancing Two-Rotation Driving Mechanism (TRDM) uses parallelogram and has low weight, high load, high accuracy, quick response and good adaptation with multi equipment. A longitudinal rotation motor assembly is constrained fully with a base assembly and drives a longitudinal rotation assembly through connecting rod parallelogram. The lateral rotation motor assembly is assembled in the hub of a longitudinal rotation assembly and rotates an equipment clamping assembly in a lateral direction. Generally, the TRDM can drive equipment clamping assembly in two rotations, with longitudinal rotation in the range of ±45° and lateral rotation in range of ±20°. A rotation limitation is reached when limitation shafts touch the end of respective grooves.Type: ApplicationFiled: August 5, 2022Publication date: March 23, 2023Applicant: VIETTEL GROUPInventors: PHAM TUAN NGUYEN, KIM BAO LE, VAN DINH PHAM, ANH TUAN CAO, QUOC TOAN TRAN, DUY TUNG NGUYEN

Patent number: 11611748Abstract: An encoder encodes transform coefficients of a transform coefficient block representing a block of a picture using a scan pattern which sequentially traverses the transform coefficients of the transform block by encoding absolute values of quantization levels of the transform coefficients. The absolute values are binarized with a binarization comprising a first part of the binarization below a cutoff value and a second part of the binarization, prefixed by a codeword of the first part of the binarization for the cutoff value, above the cutoff value. The encoder adaptively, based on previously encoded transform coefficients, decreases the cutoff value to zero monotonically during encoding of the transform coefficients so that the binarization comprises the second part of the binarization and not the first part of the binarization.Type: GrantFiled: September 25, 2020Date of Patent: March 21, 2023Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Paul Haase, Christian Rudat, Heiner Kirchhoffer, Phan Hoang Tung Nguyen, Mischa Siekmann, Heiko Schwarz, Detlev Marpe, Thomas Wiegand

Publication number: 20230075174Abstract: The coding of a media signal is rendered more efficient by describing the media signal using a sequence of samples and sequentially encoding this sequence by selecting, for a current sample, a set of quantization levels out of a plurality of quantization level sets depending on indices encoded into the data stream for previous samples of the sequence of samples, quantizing the current sample onto one level of the set of quantization levels, and encoding a quantization index to the one level for the current sample into the data stream. In other words, scalar quantization of the individual samples of the sequence of samples is used, but it is rendered dependent on quantization indices encoded into the data stream for previous samples of the sequence of samples.Type: ApplicationFiled: November 15, 2022Publication date: March 9, 2023Inventors: Heiko Schwarz, Thomas Wiegand, Phan Hoang Tung Nguyen, Detlev Marpe
