摘要

The invention relates to the encoding of an image (ICj) divided into blocks, said image containing two separate zones (Z1,Z2). Said encoding method is characterised in that it implements the following: only in the event where the current block (Bu) pertains to one (Z1) of the zones of the image: encoding (C8a) the current block using a prediction, the current block being predicted using a previously encoded and then decoded block located in the other zone of the image, the blocks of said other zone having been previously encoded and then decoded, and encoding (C100a)) information (ibc_flag) indicating the application of said prediction; and for any decoded block pertaining to the other (Z2) zone of the image, storing (C101b)) the decoded block data.
