Abstract

A video coder receives data for a block of pixels to be encoded or decoded as a current block of a current picture of a video. The video coder receives a set of transform coefficients of the current block. The video coder identifies multiple transform hypotheses. Each hypothesis includes two or more predicted transform parameters. The video coder computes a cost for each hypothesis by performing inverse transform on the transform coefficients of the current block according to the predicted transform parameters of the hypothesis. The video coder signals or receives a codeword that identifies a first transform mode of a first transform parameter. The codeword is assigned to the first transform mode based on the calculated costs of the multiple transform hypotheses. The video coder encodes or decodes the current block by reconstructing the current block according to the identified first transform mode.
