According to an implementation, a single partitioning tree structure is shared between luma and chroma blocks from a root node of the partitioning tree down to a switching node and a dual partitioning tree structure is determined for luma and chroma blocks from the switching node down to a leaf node of the partitioning tree. Thus, this implementation optimizes the coding efficiency by allowing separated trees for smaller blocks, while limiting the complexity of decoding pipeline. | 2021-07-01 |
20210203930 | MONOCHROME PALETTE MODE FOR VIDEO CODING - A method of decoding video data includes determining that a current block of the video data is coded in palette mode, determining, between single tree or dual tree partitioning, that the current block is coded with single tree partitioning enabled, determining that the current block is coded in monochrome format, when the current block is coded with single tree partitioning enabled and when the current block is coded in monochrome format, determining that a number of color components used for palette mode decoding the current block is equal to one, and palette mode decoding the current block based on the determined number of color components used for palette mode decoding the current block being equal to one. | 2021-07-01 |
20210203931 | DEVICE AND METHOD FOR CODING VIDEO DATA - A method of decoding a bitstream by an electronic device is provided. An image frame of the bitstream is received, and a block unit having a block width and a block height is determined from the received image frame. The electronic device determines whether a geometric partitioning mode is disabled for the block unit based on a comparison between the block width and the block height. The block unit is divided to generate a plurality of sub-blocks predicted by different merge candidates of the block unit when the geometric partitioning mode is applied on the block unit. The predicted block is generated by predicting block unit based on a prediction mode different from the geometric partitioning mode when the geometric partitioning mode is disabled for the block unit. The block unit is reconstructed based on the predicted block. | 2021-07-01 |
20210203932 | PICTURE ENCODING DEVICE, PICTURE ENCODING METHOD, AND PICTURE ENCODING PROGRAM, AND PICTURE DECODING DEVICE, PICTURE DECODING METHOD, AND PICTURE DECODING PROGRAM - Provided is a picture encoding device that divides a picture into blocks and performs encoding for each of the divided blocks. A primary signal block divider divides a primary signal of the picture into rectangles having a predetermined size, and generates a primary signal block. A secondary signal block divider divides a secondary signal of the picture into rectangles having a predetermined size, and generates a secondary signal block. A primary signal predictor predicts a primary signal, and a secondary signal predictor predicts a secondary signal. The secondary signal predictor can perform inter prediction of predicting a secondary signal from an encoded primary signal, and the inter prediction is restricted based on at least one of a size of the primary signal block and a size of the secondary signal block. | 2021-07-01 |
20210203933 | METHOD, APPARATUS AND SYSTEM FOR ENCODING AND DECODING A TRANSFORMED BLOCK OF VIDEO SAMPLES - The present disclosure provides a method 1200 of decoding a transform block in an image frame from a bitstream. The method comprises decoding a single truncated unary binarisation from the bitstream, the single truncated unary binarisation being used for a horizontal transform and a vertical transform of a transform block of the image frame. The method then determines a type of the horizontal and vertical transform based on the decoded single truncated unary binarisation and decodes the transform block in the image frame by applying the determined type of horizontal and vertical transform to the transform block of the image. | 2021-07-01 |

20210203936 | Quantization Control for Variable Bit Depth - The quantization parameter QP is well-known in digital video compression as an indication of picture quality. Digital symbols representing a moving image are quantized with a quantizing step that is a function QSN of the quantization parameter QP, which function QSN has been normalized to the most significant bit of the bit depth of the digital symbols. As a result, the effect of a given QP is essentially independent of bit depth a particular QP value has a standard effect on image quality, regardless of bit depth. The invention is useful, for example, in encoding and decoding at different bit depths, to generate compatible, bitstreams having different bit depths, and to allow different bit depths for different components of a video signal by compressing each with the same fidelity (i.e., the same QP). | 2021-07-01 |
