Abstract: A video coder may determine a motion vector of a non-adjacent block of a current picture of the video data. The non-adjacent block is non-adjacent to a current block of the current picture. Furthermore, the video coder determines, based on the motion vector of the non-adjacent block, a motion vector predictor (MVP) for the current block. The video coder may determine a motion vector of the current block. The video coder may also determine a predictive block based on the motion vector of the current block.

Abstract: This disclosure relates to processing video data, including processing video data that is represented by an HDR/WCG color representation. In accordance with one or more aspects of the present disclosure, one or more Supplemental Enhancement Information (SEI) Messages may be used to signal syntax elements and or other information that allow a video decoder or video postprocessing device to reverse the dynamic range adjustment (DRA) techniques of this disclosure to reconstruct the original or native color representation of the video data. Dynamic range adjustment (DRA) parameters may be applied to video data in accordance with one or more aspects of this disclosure in order to make better use of an HDR/WCG color representation, and may include the use of global offset values, as well as local scale and offset values for partitions of color component values.

Abstract: This disclosure relates to processing video data, including processing video data to conform to a high dynamic range/wide color gamut (HDR/WCG) color container. As will be explained in more detail below, the techniques of the disclosure including dynamic range adjustment (DRA) parameters and apply the DRA parameters to video data in order to make better use of an HDR/WCG color container. The techniques of this disclosure may also include signaling syntax elements that allow a video decoder or video post processing device to reverse the DRA techniques of this disclosure to reconstruct the original or native color container of the video data.

Abstract: Example techniques are described to determine transforms to be used during video encoding and video decoding. A video encoder and a video decoder may select transform subsets that each identify one or more candidate transforms. The video encoder and the video decoder may determine transforms from the selected transform subsets.

Abstract: Un codificador de vídeo puede determinar un vector de movimiento de un bloque no adyacente de una imagen actual de los datos de vídeo. El bloque no adyacente no es adyacente a un bloque actual de la imagen actual. Además, el codificador de vídeo determina, basándose en el vector de movimiento del bloque no adyacente, un predictor de vector de movimiento (MVP) para el bloque actual. El codificador de vídeo puede determinar un vector de movimiento del bloque actual. El codificador de vídeo también puede determinar un bloque predictivo basándose en el vector de movimiento del bloque actual. (Traducción automática con Google Translate, sin valor legal)
