    • The invention relates to a method for deriving motion data for a macroblock of a high resolution picture, called high layer macroblock, from motion data of macroblocks of a low resolution picture, called base layer macroblock. The method comprises the following steps: - dividing (2100) the high layer macroblock in elementary blocks; - computing (2200), for each elementary block, an intermediate position within the low resolution picture from the elementary block position depending on the coding modes of the high layer macroblock and of the high and low resolution pictures; - identifying (2300) the base layer macroblock, called base_ MB, comprising the pixel located at the intermediate position; - computing (2400) a final position within the low resolution picture from the virtual base layer position depending on the coding modes of the base_ MB, of the high layer macroblock and of the high and low resolution pictures; - identifying (2500) the base layer macroblock, called real_ base_ MB, comprising the pixel located at the final position; and deriving (2600) motion data, for the high layer macroblock, from motion data of the identified real_ base_ MB.

    • The invention relates to a method for coding a sequence of pictures in the form of a scalable stream comprising a base layer and an enhancement layer. The method comprises the following steps: determine (E101, E102) in each picture of the sequence, called first sequence of pictures, a cropping window (W1); subsample (E103), for each picture of the first sequence, the picture part delimited by the cropping window (W1) in such a manner as to construct a second sequence of pictures, and code (E12, E14, E16) the second sequence of pictures as base layer of the scalable stream and the first sequence of pictures as enhancement layer of the scalable stream. According to the invention, the cropping window (W1) is determined in a picture of the first sequence according to the following steps: determine (E101), in the picture, a first cropping window (WO), and determine (E102) a second cropping window surrounding the first cropping window (WO) such that the second cropping window is compliant with at least one predefined constraint imposed by the coding step (E12, E14, E16), the cropping window (W1) of the picture being the second cropping window.
