Abstract: This disclosure proposes various techniques for limiting the number of bins that are coded using an adaptive context model with context adaptive binary arithmetic coding (CABAC). In particular, this disclosure proposes to limit the number of bins that use CABAC for coding level information of transform coefficients in a video coding process.

Abstract: A video coder decodes a coding unit (CU) of video data. In decoding the video data, the video coder determines that the CU was encoded using the color space conversion. The video coder determines the initial quantization parameter (QP), determines the final QP that is equal to a sum of the initial QP and a QP offset, and inverse quantizes, based on the final QP, a coefficient block, then reconstructs the CU based on the inverse quantized coefficient blocks.

Abstract: In an example, a method of processing video data includes splitting a current block of video data into a plurality of sub-blocks for deriving motion information of the current block, where the motion information indicates motion of the current block relative to reference video data. The method also includes deriving, separately for each respective sub-block of the plurality of sub-blocks, motion information comprising performing a motion search for a first set of reference data that corresponds to a second set of reference data outside of each respective sub-block. The method also includes decoding the plurality of sub-blocks based on the derived motion information and without decoding syntax elements representative of the motion information.

Abstract: L'invention concerne un appareil conçu pour coder des informations vidéo, comprenant une unité de mémoire et un processeur en communication avec l'unité de mémoire. L'unité de mémoire est conçue pour stocker des informations vidéo associées à une couche d'amélioration comportant un premier bloc et une couche de base comportant un second bloc, le second bloc dans la couche de base correspondant au premier bloc dans la couche d'amélioration. Le processeur est conçu pour prédire, au moyen d'une prédiction entre couches, le premier bloc dans la couche d'amélioration en fonction des informations dérivées du second bloc dans la couche de base. Au moins une portion du second bloc se trouve à l'extérieur d'une région de référence de la couche de base, la région de référence étant disponible pour servir à la prédiction entre couches du premier bloc. Le processeur peut coder ou décoder les informations vidéo.

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 device for decoding video data includes a memory configured to store video data and one or more processors configured to: receive a first block of the video data; determine a quantization parameter for the first block; in response to determining that the first block is coded using a color-space transform mode for residual data of the first block, modify the quantization parameter for the first block; perform a dequantization process for the first block based on the modified quantization parameter for the first block; receive a second block of the video data; receive a difference value indicating a difference between a quantization parameter for the second block and the quantization parameter for the first block; determine the quantization parameter for the second block based on the received difference value and the quantization parameter for the first block; and decode the second block based on the determined quantization parameter.

Abstract: An apparatus configured to code video information includes a memory unit and a processor in communication with the memory unit. The memory unit is configured to store video information associated with an enhancement layer having a first block and a base layer having a second block, the second block in the base layer corresponding to the first block in the enhancement layer. The processor is configured to predict, by inter layer prediction, the first block in the enhancement layer based on information derived from the second block in the base layer. At least a portion of the second block is located outside of a reference region of the base layer, the reference region being available for use for the inter layer prediction of the first block. The processor may encode or decode the video information.
