"Methods And Devices For Coding And Decoding A Data Stream Representing At Least One Image"
Abstract: The invention relates to a coding method and a method for decoding a coded data stream 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 a coding mode of the current block is decoded (E42) from the data stream. When the coding mode of the current block corresponds to a first coding mode, the current block is decoded (E43) using a first determined quantization step (E430) for de-quantifying, in the transformed domain, a prediction residual associated with the current block. When the coding mode of the current block corresponds to a second coding mode, the current block is decoded (E44) using a second determined quantization step (E441) for de-quantifying, in the spatial domain, a prediction residual associated with the current block. According to the invention, the first quantization step and the second quantization step are determined according to a same quantization parameter.
