The method includes partitioning a block of video data into a plurality of sub-partitions, obtaining a number of most probable intra predictions based on intra prediction modes of neighboring blocks of a current block and determining an intra prediction mode to predict the samples of the block sub-partitions, selecting an optimal transform combination from DCT-II, DST-VII and DCT-VIII transform kernels for each sub-partition, obtaining residual coefficients of a first sub-partition and deriving dequantized residual coefficients of the first sub-partition, deriving residual samples of the first sub-partition by performing inverse transform on dequantized residual coefficients of the first sub-partition in horizontal and vertical directions, deriving prediction samples of the first sub-partition, and deriving the reconstructed samples of the first sub-partition, and deriving prediction samples of a second sub-partition."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and devices for intra sub-partition coding mode","description":"The present disclosure relates to an intra sub-partition (ISP) method of decoding a video signal.
