Abstract (en)

[origin: WO2020254723A1] A method for video coding comprises receiving a source picture; partitioning the source picture into a set of non-overlapping blocks (510); for a first block being coded, coding syntax elements of various coding tools into the bitstream (530) according to a pre-defined order (520); for any one or more subsequent block, determining a probability of a usage of each of the various coding tools in any one or more previous blocks; deriving a probability model according to the determined probabilities (540); defining an order for syntax elements for a block according to the probability model (550); and encoding syntax elements of the block into a bitstream (530) according to the defined order (520). In some embodiments, the probability of usage of each coding tool is determined according to a learning process involving a neural network.
