Abstract (en)
[origin: WO2020157413A1] The invention relates to a method for coding data corresponding to a video sequence, in a spatial-resolution scalable bitstream, comprising a base layer and at least one enhancement layer. The method comprises, for at least one image of the video sequence, obtaining, from said image, a first image, partitioning the first image into blocks, each block having a given size, and coding at least one block of the first image to generate the base layer, obtaining, from said image, a second image, the method further comprising partitioning the second image into blocks by inferring the initial size of at least one of the blocks from the size of a corresponding block in the first image, said at least one block of the second image having an initial spatial resolution, determining a coding spatial resolution associated with said at least one block from a set of predetermined spatial resolutions, and coding data representative of said at least one block, based on the determined coding spatial resolution, to generate at least one enhancement layer.
