==VIDEO CODING METHOD ON BASIS OF TRANSFORMATION, AND DEVICE THEREFOR - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18244648 titled 'VIDEO CODING METHOD ON BASIS OF TRANSFORMATION, AND DEVICE THEREFOR

==Simplified Explanation==

The video decoding method described in this patent application involves deriving transform coefficients for a current block based on residual information. This includes deriving a zero-out block that indicates the region where effective transform coefficients may exist in the current block. The zero-out block is determined using flag information that indicates whether multiple transform selection (MTS), which involves using multiple transform kernels, can be applied to the current block.
