Simplified Explanation

The abstract describes a method for decoding a video signal using a reduced transform. The method involves obtaining a transform index that indicates the transform kernels applied to the horizontal and vertical directions of a current block in the video signal. Based on the transform index and the size of the current block, a region is determined where the transform is applied. The coefficients of the remaining region in the current block are derived as zero. Finally, an inverse transform is performed on the region where the transform is applied using the indicated transform kernels.


Original Abstract Submitted

A method for decoding a video signal based on reduced transform includes the steps of: obtaining, from the video signal, a transform index indicating transform kernels applied to horizontal and vertical directions of a current block; determining a region in which a transform is applied to the current block based on the transform kernels indicated by the transform index and a size of the current block; deriving, as zero, coefficients of a remaining region other than the region to which the transform is applied within the current block; and performing an inverse transform on the region to which the transform is applied using the transform kernels indicated by the transform index.
