Abstract: A method of decoding video data including receiving a bitstream that includes a sequence of bits that forms a representation of a coded picture of the video data, partitioning the coded picture of the video data into a plurality of blocks using three or more different partition structures, and reconstructing the plurality of blocks of the coded picture of the video data. Partitioning the coded picture of the video data may include partitioning the coded picture of the video data into the plurality of blocks using the three or more different partition structures, wherein at least three of the three or more different partition structures may be used at each depth of a tree structure that represents how a particular block of the coded picture of the video data is partitioned.

Abstract: In an example, a method of coding video data may include selecting, as part of an entropy coding process, a context for a syntax element associated with a current coding unit (CU) based on information relating to CU depth of one or more neighboring CUs relative to the current CU. The syntax element may represent whether the current CU is split into sub-CUs. The method may include entropy coding the syntax element based on the selected context.

Abstract: Coding a motion vector difference (MVD) during an inter-prediction process. Example techniques may include determining a particular coding and/or signaling method for an MVD from among two or more MVD coding and/or signaling techniques. A video coder (e.g., a video encoder and/or a video decoder) may determine a particular MVD coding and/or signaling technique based on characteristics of video data or coding methods, including MV precision, Picture Order Count (POC) difference, or any other already coded/decoded information of a block of video data.

Abstract: A device for decoding video data includes a memory configured to store the video data; and one or more processors configured to decode syntax information that indicates a selected intra prediction mode for the block of video data from among a plurality of intra prediction modes. The one or more processors apply an N-tap intra interpolation filter to neighboring reconstructed samples of the block of video data according to the selected intra prediction mode, wherein

Abstract: A method of decoding video data includes constructing a motion vector candidate list of merge candidates for the current block of video data based on motion information from a number of neighboring blocks relative to the current block, wherein the number of neighboring blocks considered for the motion vector candidate list is based on the size of the current block, and wherein the number of neighboring blocks is greater than 5. In some examples, the method includes deriving a histogram of motion vector information for the neighboring blocks, and constructing the motion vector candidate list based on the derived histogram.

Abstract: An example method of entropy coding video data includes determining a window size of a plurality of window sizes for a context of a plurality of contexts used in a context-adaptive coding process to entropy code a value for a syntax element of the video data; entropy coding, based on a probability state of the context, a bin of the value for the syntax element; updating a probability state of the context based on the window size and the coded bin. The example method also includes entropy coding a next bin with the same context based on the updated probability state of the context.

Abstract: Un procedimiento de decodificación de datos de vídeo, el procedimiento comprendiendo: almacenar (172) un vector de disparidad de un bloque particular de un segmento de una imagen actual de los datos de vídeo como un vector de disparidad derivado (DDV) para el segmento, en el que el segmento incluye múltiples bloques y sólo hay un DDV para el segmento; determinar (174), realizando un proceso de derivación de Vector de Disparidad Basado en Bloques Vecinos (NBDV), un vector de disparidad para un bloque actual, en el que el bloque actual es uno de los bloques del segmento, en el que realizar el proceso de derivación de NBDV comprende establecer el vector de disparidad para el bloque actual como el DDV para el segmento cuando el proceso de derivación de NBDV no identifica ningún vector de movimiento de disparidad disponible a partir de bloques vecinos en el tiempo o a partir de bloques vecinos en el espacio; y almacenar (176), como el DDV para el segmento, el vector de disparidad para el bloque actual.
