VIDEO SIGNAL PROCESSING METHOD AND APPARATUS USING SECONDARY TRANSFORM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18341936 Titled 'VIDEO SIGNAL PROCESSING METHOD AND APPARATUS USING SECONDARY TRANSFORM'
Simplified Explanation
The abstract describes a video signal decoding apparatus that includes a processor. The processor is designed to perform certain tasks related to decoding a video signal. It parses a syntax element that is associated with a secondary transform of a coding unit. The parsing is based on whether the prediction method of the coding unit is MIP (Matrix based Intra Prediction). The processor then checks whether the secondary transform is applied to a transform block within the coding unit, using the parsed syntax element. If the secondary transform is applied, the processor obtains one or more inverse transform coefficients by performing an inverse transform of the secondary transform. Finally, the processor obtains a residual sample for the transform block based on the obtained inverse transform coefficients.
Original Abstract Submitted
A video signal decoding apparatus, comprising a processor, wherein the processor is configured to: parse a syntax element related to a secondary transform of a coding unit based on whether a prediction method of the coding unit is MIP (Matrix based Intra Prediction), check whether or not the secondary transform is applied to a transform block included in the coding unit based on the parsed syntax element, obtain one or more inverse transform coefficients based on an inverse transform of the secondary transform when the secondary transform is applied to the transform block, obtain a residual sample for the transform block based on the one or more inverse transform coefficients.
