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.
