A video sequence is coded in the form of a base level and an refinement level. A group of pictures of the base level comprises intra coded or mono-predicted end images (I,P) and bi-predicted images (B1 , B2, B3), the refinement level comprises at least one image (E2, E4,...,E16) with no temporal correspondent in the base level. Use is made of predictive coding of said image with no temporal correspondent (E2, E4,..., E16) by making reference to a plurality of images, each image of said plurality being an image of the refinement level with no temporal correspondent in the base level (E4, E8, E12, E14) or an image of the refinement level (E1 , E17) corresponding temporally to an end image (I1P). |
