摘要： Disclosed is a method for decoding a current block in a current picture included in a high-level layer performed based on a reference picture included in a low-level layer and having a different resolution. A prediction mode for the current block, a decoded residual signal, and decoding information for the current block, are obtained. When the prediction mode is the inter-prediction, a prediction signal for the current block is generated based on the decoding information. A reconstructed block is then generated by adding the prediction signal to the residual signal. Filtering is then performed for correcting the different resolution that is applied to a reference block included in the reference picture such that the different resolution matches a resolution of the current block.

摘要： A video decoding method for decoding a target block using intra prediction comprises decoding, from a bitstream, boundary line information specifying at least one boundary line for partitioning the target block. The boundary line information allows partitioning the target block into a plurality of non-rectangular blocks. The method further comprises determining intra prediction modes for the non-rectangular blocks based on the boundary line information; generating a prediction block of the target block by performing intra prediction on each of the non-rectangular blocks using the intra prediction modes; reconstructing a residual block of the target block from the bitstream; and reconstructing the target block by adding the prediction block and the residual block.

摘要： For encoding and decoding images, an image encoding device divides each picture into sub-pictures that can be independently displayed, and signals layout information about the sub-pictures, and an image decoding device identifies each sub-block through the layout information and decodes the sub-pictures. A video decoding apparatus and method are configured to decode a bitstream containing an encoded sequence of pictures which are partitioned into a plurality of subpictures including a plurality of coding tree blocks.

摘要： The present disclosure is related to a method and an apparatus for generating residual signals using reference between components. The video encoding/decoding apparatus and method derive residual signals of a chroma component of a current block. In deriving the residual signals of the chroma component, the video encoding/decoding apparatus and method use the residual signals of a previously reconstructed block without transmitting residual signals of part of the chroma component of the current block.
