Publication number: 20250071280Abstract: Different quantization matrices may be transmitted corresponding to different block sizes, color components and prediction modes. To more efficiently signal the coefficients of the quantization matrices, in one implementation, a unified matrix identifier matrixId is used, based on a size identifier (sizeId) that relates to CU size with larger sizes listed first, and a matrix type (matrixTypeId) with luma QMs listed first. For example, the unified identifier is derived as: matrixId=N*sizeId+matrixTypeId, where N is the number of possible type identifiers, e.g., N=6. This single identifier allows referring to any previously transmitted matrix when using prediction (copy), and transmitting larger matrices first avoids interpolation in the prediction process. When a block uses the Intra Block Copy prediction mode, QM identifier may be derived as if the block uses the INTER prediction mode.Type: ApplicationFiled: November 5, 2024Publication date: February 27, 2025Inventors: Philippe DE LAGRANGE, Fabrice LELEANNEC, Karam NASER, Edouard FRANCOIS, Pierre ANDRIVON, Ya CHEN

Publication number: 20240414346Abstract: Systems, methods, and instrumentalities are disclosed for cross-component depth-luma coding. Depth information may be used as information for joint or cross-component coding of texture information (e.g., luma, chroma, or R, G, B colour component information).

In examples, a device may determine whether a coding mode, such as a joint depth-color coding mode (JDCC) (e.g., joint depth-luma coding mode (JDLC)) is used for a current block. If JDCC coding mode is used for the block, then the device may decode depth sample(s) in the block and predict the corresponding color sample(s) (e.g., luma sample(s) and/or chroma sample(s)) in the block based on the decoded depth sample(s).Type: ApplicationFiled: October 5, 2022Publication date: December 12, 2024Applicant: InterDigital CE Patent Holdings, SASInventors: Edouard Francois, Gagan Bihari Rath, Karam Naser, Tangi Poirier
