Abstract (en)

[origin: WO2018167419A1] The invention relates to the encoding of at least one image (ICj) divided into blocks, implementing the following: - encoding (C2) a first syntax element (ES) associated with a characteristic of said at least one image; - encoding (C8), for a current block to be encoded associated with at least one encoding parameter, the data of the current block, said encoding method being characterised in that: - if the first syntax element (ES) is encoded according to a first predefined value (VCES) representing the characteristic of the image, a second syntax element (ES2) representing the value of said at least one encoding parameter is encoded (C7) only if the current block belongs to a predefined zone (Z2) of the image; - if the first syntax element (ES) is encoded according to a second predefined value (VCES2) representing the characteristic of the image, the second syntax element (ES2) is encoded (C7), whether or not the current block belongs to the predefined zone.
