ENCODING/DECODING METHOD FOR VIDEO SIGNAL AND DEVICE THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18094047 titled 'ENCODING/DECODING METHOD FOR VIDEO SIGNAL AND DEVICE THEREFOR
Simplified Explanation
The present invention is a video signal processing method and device that focuses on decoding a video signal. The method includes several steps such as checking if a transfer skip is applied to a current block, obtaining a transform index from the video signal, checking if the transform type set includes DCT2, determining the region for primary transform application based on the checking result, and performing an inverse transform on the region using the transform types included in the transform type set.
- The method checks if a transfer skip is applied to a current block.

Original Abstract Submitted
Embodiments of the present invention provide a video signal processing method and device. Particularly, a method for decoding a video signal, may comprise the steps of: checking whether a transfer skip is applied to a current block; obtaining, from a video signal, a transform index for indicating a transform type set applied to the current block when the transform skip is not applied to the current block, wherein the transform type set includes transform types applied to the current block in horizontal and vertical directions; checking whether the transform type set includes DCT2; determining a region to which a primary transform is applied based on a checking result; and performing an inverse transform on the region to which the primary transform is applied in the horizontal and vertical directions using the transform types included in the transform type set.
