Title:

INTRA-PREDICTION-BASED VIDEO SIGNAL PROCESSING METHOD AND APPARATUS

Document Type and Number:

Japanese Patent JP2023105114

Kind Code:

A

Abstract:

To provide video signal processing method and apparatus for encoding or decoding video signals.SOLUTION: A video signal processing method includes the steps of determining whether an intra sub-partition (ISP) mode is applied to the current block, dividing the current block into a plurality of horizontal or vertical rectangular transform blocks when the ISP mode is applied to the current block, generating predictive blocks for the transform blocks by performing intra prediction on each of the transform blocks, and reconstructing the current block on the basis of the residual block of the transform block and the predictive block.SELECTED DRAWING: Figure 20
