The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: A method of using cascaded vectors for subblock coding is provided. A video coder receives data to be encoded or decoded as a current block comprising a plurality of current subblocks. The video coder identifies a plurality of collocated subblocks in a collocated picture that correspond to the plurality of current subblocks based on a motion shift provided by a cascaded vector that is a sum of at least two recursively traced vectors, each traced vector being a motion vector or a block vector. The video coder derives predictors for the plurality of current subblocks based on motion information of the plurality of collocated subblocks. A cascaded vector is derived based on the motion information of a collocated subblock to derive a predictor for a current subblock. The video coder encodes or decodes the current block by using the derived predictors of the plurality current subblocks.
