Abstract: In an example, a method of decoding video data may include receiving a palette mode encoded block of video data of a picture. The method may include receiving encoded palette mode information for the palette mode encoded block of video data. The encoded palette mode information may include a plurality of instances of a first syntax element and a plurality of syntax elements that are different from the first syntax element. The method may include decoding, using bypass mode, the plurality of instances of the first syntax element before decoding the plurality of syntax elements that are different from the first syntax element using context mode. The method may include decoding, using context mode, the plurality of syntax elements that are different from the first syntax element after decoding the plurality of instances of the first syntax element using bypass mode.

Abstract: In one example, a device for coding video data includes a video coder configured to determine values for coded sub-block flags of one or more neighboring sub-blocks to a current sub-block, determine a context for coding a transform coefficient of the current sub-block based on the values for the coded sub-block flags, and entropy code the transform coefficient using the determined context.

Abstract: This disclosure relates to methods and apparatus for encoding and decoding video data. In an example an intra-mode for predicting a current block of video data and most probable intra-modes (MPMs) for predicting the current block of video data may be determined. An index for each of the MPMs based on an order in which the intra- mode for predicting the current block is compared to the MPMs may be determined. When one of the MPMs for predicting the current block matches the intra-mode for predicting the current block, the index of the matching MPM is signaled.

Abstract: An example method of coding video data includes coding, from a coded video bitstream, a syntax element that indicates whether a transpose process is applied to palette indices of a palette for a current block of video data; decoding, from the coded video bitstream and at a positon in the coded video bitstream that is after the syntax element that indicates whether the transpose process is applied to palette indices of the palette for the current block of video data, one or more syntax elements related to delta quantization parameter (QP) and/or chroma QP offsets for the current block of video data; and decoding the current block of video data based on the palette for the current block of video data and the one or more syntax elements related to delta QP and/or chroma QP offsets for the current 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 receive a slice of the video data, parse an intra block copy (IBC) syntax element to determine that an IBC mode is enabled for the slice, parse a slice type syntax element associated with the slice to determine the slice is an I slice, and decode the slice as an I slice by decoding all blocks of the slice using intra prediction coding modes.

Abstract: In one example, a device for coding video data includes a video coder configured to determine whether a transform coefficient of a video block is a DC transform coefficient, when the transform coefficient is determined to be the DC transform coefficient of the video block, determine a context for coding the transform coefficient based on the transform coefficient being the DC transform coefficient without regard for a size of the video block, and entropy code the transform coefficient using the determined context.

Abstract: For each prediction unit (PU) belonging to a coding unit (CU), a video coder generates a candidate list. The video coder generates the candidate list such that each candidate in the candidate list that is generated based on motion information of at least one other PU is generated without using motion information of any of the PUs belonging to the CU. After generating the candidate list for a PU, the video coder generates a predictive video block for the PU based on one or more reference blocks indicated by motion information of the PU. The motion information of the PU is determinable based on motion information indicated by a selected candidate in the candidate list for the PU.

Abstract: Un aparato configurado para codificar información de video incluye una unidad de memoria y un procesador en comunicación con la unidad de memoria. La unidad de memoria está configurada para almacenar la información de video asociada con una capa de acrecentamiento que tiene un primer bloque y una capa base que tiene un segundo bloque, el segundo bloque en la capa base correspondiendo al primer bloque en la capa de acrecentamiento. El procesador está configurado para predecir, mediante la predicción inter capa, el primer bloque en la capa de acrecentamiento en base a la información derivada a partir del segundo bloque en la capa base. Al menos una porción del segundo bloque se encuentra ubicada por fuera de una región de referencia de la capa base, la región de referencia estando disponible para su uso para la predicción inter capa del primer bloque.

Abstract: A method of coding delta quantization parameter values is described. In one example a video decoder may receive a delta quantization parameter (dQP) value for a current quantization block of video data wherein the dQP value is received whether or not there are non zero transform coefficients in the current quantization block. In another example a video decoder may receive the dQP value for the current quantization block of video data only in the case that the QP Predictor for the current quantization block has a value of zero and infer the dQP value to be zero in the case that the QP Predictor for the current quantization block has a non zero value and there are no non zero transform coefficients in the current quantization block.
