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: A method for decoding video data provided in a bitstream, where the bitstream includes a coding unit (CU) coded in palette mode, includes: parsing a palette associated with the CU provided in the bitstream; parsing one or more run lengths provided in the bitstream that are associated with the CU; parsing one or more index values provided in the bitstream that associated with the CU; and parsing one or more escape pixel values provided in the bitstream that are associated with the CU. The escape pixel values may be parsed from consecutive positions in the bitstream, the consecutive positions being in the bitstream after all of the run lengths and the index values associated with the CU. The method may further include decoding the CU based on the parsed palette, parsed run lengths, parsed index values, and parsed escape values.

Abstract: A method of decoding video data includes determining, by a video decoder, a neighboring block in a current frame is inter coded. The method includes, in response to determining the neighboring block is inter coded, determining, by the video decoder, a template for a current block in the current frame based on a partial reconstruction of the neighboring block. The method includes determining, by the video decoder, a reference block in a reference frame corresponding to the template for the current block and determining, by the video decoder, motion vector information for the current frame based on the reference block and the template. The method includes generating, by the video decoder, a predictive block for the current block of video data based on the motion vector information and decoding, by the video decoder, the current block of video data based on the predictive block.

Abstract: An apparatus configured to decode video data that comprises a memory configured to store the video data; and one or more processors. The one or more processors are configured to: receive a bitstream that is constrained such that escape values used in a palette mode for decoding the video data are no greater than a maximum value, wherein the bitstream includes information for determining at least one escape value representing a sample in a block of the video data to be decoded; and reconstruct the sample in the block of the video data using the information for determining the at least one escape value.

Abstract: A device for encoding or decoding video data may clip first residual data based on a bit depth of the first residual data. The device may generate second residual data at least in part by applying an inverse Adaptive Color Transform (IACT) to the first residual data. Furthermore, the device may reconstruct, based on the second residual data, a coding block of a coding unit (CU) of the video data.

Abstract: sinalização dos parâmetros de predição intra de matriz em codificação de vídeo. um codificador de vídeo determina uma pluralidade de conjuntos de parâmetros (mps) de predição intra matriz (mip) disponíveis para uma imagem de dados de vídeo. a pluralidade de mpss disponíveis é uma união de (i) um subconjunto de todos os mpss padrões e (ii) um conjunto de mpss adicionais que são sinalizados no fluxo de bits. cada um dos mpss padrões está associado a um modo de mip predefinido em um codec. cada um dos conjuntos de mps adicionais está associado a um novo modo de mip em um conjunto de novos modos de mip. o decodificador de vídeo usa um modo de mip associado a um mps na pluralidade de mpss disponíveis para gerar um bloco de predição para um bloco atual da imagem.

Abstract: A video coder may be configured to code video data by performing splitting of a coding unit (CU) of video data using intra sub-partition (ISP) to form a set of prediction blocks. The video coder may group a plurality of the prediction blocks from the set of prediction blocks into a first prediction block group (PBG). The video coder may reconstruct samples of prediction blocks included in the first PBG independently of samples of other prediction blocks included in the first PBG.
