Abstract: A method and device for controlling coding tools are provided. The video decoding method includes decoding, from a high level of a bitstream, an enable flag indicating whether one or more coding tools are enabled. The coding tools includes a first coding tool that encodes sample values using luma component mapping based on a piecewise linear model. The method includes acquiring a value of an application flag depending on a value of the enable flag, by setting the application flag indicating whether to apply the coding tools to a predetermined value, or by decoding the application flag from a low level of the bitstream, the application flag including a first application flag indicating whether to apply the first coding tool. The coding tools are operated when the value of the application flag is a value indicating that the coding tools are applied.

Abstract: A method and an apparatus for performing inverse transform on transform coefficients of a current block are disclosed. The method comprises: decoding, from a sequence parameter set (SPS) level of a bitstream, one or more intra multiple transform selection (MTS) syntax elements that control the MTS of an intra prediction mode and one or more inter MTS syntax elements that control the MTS of an inter prediction mode; determining one or more transform kernels to be used for the inverse transform of the transform coefficients, on the basis of a prediction mode of the current block, the one or more intra MTS syntax elements, and the one or more inter MTS syntax elements; and performing the inverse transform on the transform coefficients by using the determined one or more transform kernels.

Abstract: A video decoding apparatus is provided for decoding pictures using inter-prediction. The video decoding apparatus includes a predictor that generates affine prediction samples for respective subblocks in a target block in a current picture to be decoded by performing affine motion prediction on a subblock-by-subblock basis using control point motion vectors which respectively correspond to corners of the target block. The predictor also modifies sample values of the affine prediction samples by executing a first coding tool, the first coding tool compensating for motion according to sample positions in each of the subblocks using the control point motion vectors.
