Patent ID: 8320692

Claim:
A method for encoding image data, an image being sub-divided into blocks, said method implementing the steps of: predicting the data of a current block as a function of at least one other already encoded block known as a reference block, delivering a predicted block, wherein predicting takes account of a set of encoded blocks that are neighbors of said current block, comprising blocks not yet considered according to a predetermined write scan order; determining information on residues by comparison of said current block and of said predicted block; encoding said information on residues; transmitting and/or storing a data signal comprising a set of data associated with each block, comprising said information on residues according to said predetermined write scan order for scanning the writing of the data associated with the blocks encoded in said signal; building a dependency tree associating, with a current block, at least one reference block from which the predicted block associated with said current block has been predetermined; and inserting information representing said dependency tree in said set of data associated with each block.
