IMAGE ENCODING/DECODING METHOD AND DEVICE THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18386135 titled 'IMAGE ENCODING/DECODING METHOD AND DEVICE THEREFOR
Simplified Explanation
The present invention is a video signal decoding method based on Multiple Transform Selection (MTS), which involves parsing a syntax element to determine if MTS applies to the inverse transformation of a current block. The method includes steps such as performing inverse quantization on the current block, determining vertical and horizontal transform types based on the syntax element, and deriving a residual sample array through inverse transformation using the selected transform types.

Original Abstract Submitted
The present invention relates to a video signal decoding method based on a Multiple Transform Selection (MTS). The method may comprise the steps of: parsing a first syntax element representing whether MTS applies to the inverse transformation of a current block, wherein the MTS represents a transform mode which uses a transform type other than a default transform type predefined for the current block; by performing inverse quantization on the current block, deriving an inverse-quantized transform coefficient array having the width and the height of the current block; determining, on the basis of the first syntax element, a vertical transform type applying to the vertical direction of the current block, and a horizontal transform type applying to the horizontal direction of the current block; and, by performing inverse transformation on the inverse-quantized transform coefficient array by using the vertical transform type and the horizontal transform type, deriving a residual sample array having the width and the height of the current block.
