ENCODING/DECODING METHOD FOR VIDEO SIGNAL AND DEVICE THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18231662 titled 'ENCODING/DECODING METHOD FOR VIDEO SIGNAL AND DEVICE THEREFOR
Simplified Explanation
The present invention is about a video signal processing method and device. It specifically focuses on a method for decoding a video signal. Here are the key points:
- The method checks if a transfer skip is applied to a current block.
- If the transfer skip is not applied, the method obtains a transform index from the video signal. This index indicates the transform type set applied to the current block.
- The transform type set includes transform types applied to the current block in horizontal and vertical directions.
- The method checks if the transform type set includes DCT2.
- Based on the checking result, the method determines a region to which a primary transform is applied.
- Finally, the method performs an inverse transform on the determined region using the transform types included in the transform type set, in both horizontal and vertical directions.
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.
