Abstract: A method of decoding video data comprises receiving a bitstream of encoded video data, the encoded video data representing partitioned luma blocks and partitioned chroma blocks, wherein the chroma blocks are partitioned independently of the luma blocks, determining a respective coding mode corresponding to the respective partitioned luma blocks, decoding the respective partitioned luma blocks according to the determined respective coding modes, decoding a first syntax element indicating that the respective coding modes associated with the respective partitioned luma blocks are to be used for decoding a first partitioned chroma block, wherein the first partitioned chroma block is aligned with two or more partitioned luma blocks, determining a chroma coding mode for the first partitioned chroma block according to a function of the respective coding modes of the two or more partitioned luma blocks, and decoding the first partitioned chroma block in accordance with the determined chroma coding mode.

Abstract: A method of decoding video data comprising receiving a block of video data encoded using a position dependent intra prediction combination (PDPC) mode, the block of video data having a non-square shape defined by a width and a height, determining one or more PDPC parameters based on one or more of the width or the height of the block of video data, and decoding the block of video data using the PDPC mode and the determined PDPC parameters.

Abstract: A video decoder may receive, in a bitstream that comprises an encoded representation of video data, information indicating whether a residual block is partitioned and information indicating a partition tree type for the residual block based on the residual block being partitioned, wherein the residual block is indicative of a difference between a current block and a prediction block. The video decoder may determine, based on the received information that the residual block is partitioned and the partition tree type for the residual block, a plurality of residual sub-blocks into which the residual block is partitioned according to the partition tree type. The video decoder may produce the residual data for the current block based at least in part on the residual block being partitioned according to the partition tree type into the plurality of residual sub-blocks and may decode the current block using the residual data.

Abstract: Un método ejemplar incluye inferir, para un bloque de transformada actual de un bloque de video actual, un tipo de transformada de entre una pluralidad de tipos de transformada que incluye una o más transformadas de coseno discretas (DCTs) y una o más transformadas de seno discretas (DSTs), en donde la inferencia del tipo de transformada comprende: determinar un tamaño del bloque de transformada actual; determinar si el bloque de video actual es dividido utilizando división intra-subbloque (ISP); y en respuesta a determinar que el tamaño del bloque de transformada actual es menor que un umbral y que el bloque de video actual es dividido utilizando ISP, seleccionar una DST particular de una o más DSTs como el tipo de transformada seleccionado; transformar, utilizando el tipo de transformada seleccionado, el bloque de transformada actual para obtener un bloque de datos residuales reconstruidos para el bloque de video; y reconstruir, con base en los datos residuales reconstruidos para el bloque de video, el bloque de video.

Abstract: An example method includes inferring, for a current transform block of a current video block, a transform type from a plurality of transform types that includes one or more discrete cosine transforms (DCTs) and one or more discrete sine transforms (DSTs), wherein inferring the transform type comprises: determining a size of the current transform block; determining whether the current video block is partitioned using intra-subblock partitioning (ISP); and responsive to determining that the size of the current transform block is less than a threshold and that the current video block is partitioned using ISP, selecting a particular DST of the one or more DSTs as the selected transform type; transforming, using the selected transform type, the current transform block to obtain a block of reconstructed residual data for the video block; and reconstructing, based on the reconstructed residual data for the video block, the video block.

Abstract: Un decodificador de video puede recibir, en un flujo de bits que comprende una representación codificada de datos de video, información indicativa si un bloque residual está particionado e información que indica una partición tipo árbol para el bloque residual en base al bloque residual estando particionado, en donde el bloque residual es indicativo de una diferencia entre el bloque actual y un bloque de predicción. El decodificador de video puede determinar, en base a la información recibida que el bloque residual está particionado y la partición tipo árbol para el bloque residual, una pluralidad de subbloques residuales en el cual el bloque residual está particionado de acuerdo con la partición tipo árbol. El decodificador de video puede producir los datos residuales para el bloque actual en base al menos en parte en el bloque residual estando particionado de acuerdo con la partición tipo árbol en una pluralidad de subbloques residuales y puede decodificar el bloque actual usando los datos residuales.
