The invention relates to a method for displaying a sequence of pictures coming in the form of a multilayer stream comprising a base layer representative of the pictures of the sequence at a first resolution and/or first quality and at least one enhancement layer representative of the sequence pictures at a second resolution and/or second quality. The method comprises the following steps: - decode (100) the base layer from a random access point of the base layer and at least up to the decoding of a random access point of the enhancement layer to reconstruct pictures of the base layer, - display (110) the reconstructed pictures of the base layer, - decode (130) the enhancement layer from the random access point of the enhancement layer to reconstruct pictures of the enhancement layer, and - display (150) the reconstructed pictures of the enhancement layer. The method further comprises a processing step (140) of the pictures of the enhancement layer before their display in such a way that the variation of the image content and/or of its quality between the picture of the base layer corresponding to the time of the random access point of the enhancement layer and the pictures of the enhancement layer is gradual. |
