Abstract (en)
[origin: WO2020058593A1] The invention relates to a method for decoding a stream of encoded data representing at least one image that is split into blocks. For at least one block of the image, referred to as the current block, information indicating an encoding mode of the current block is decoded (E42) from the data stream. When the encoding mode of the current block corresponds to a first encoding mode, the decoding (E433) of a prediction residual associated with the current block is performed using a first group of syntax elements, while, when the encoding mode of the current block corresponds to a second encoding mode, decoding (E442) of the prediction residual associated with the current block is performed using a second group of syntax elements, which is a subset of syntax elements of said first group of syntax elements.
