CODING OF INFORMATION ABOUT TRANSFORM KERNEL SET - A simplified explanation of the abstract

This abstract first appeared for US patent application 18412045 titled 'CODING OF INFORMATION ABOUT TRANSFORM KERNEL SET

Simplified Explanation

The image decoding method described in the abstract involves acquiring a multiple transform selection (MTS) index and residual information from a bitstream, deriving transform coefficients for the current block based on the residual information, and generating residual samples of the current block based on the MTS index and the transform coefficients. Context coding is performed on at least one bin of the MTS index, using values of increase and decrease in a context index related to the MTS index.
